Infiniti G
Encyclopedia
The Infiniti G is a compact executive
/entry-level luxury car produced by Nissan's luxury brand Infiniti
. The first two generations of the Infiniti G (P10 and P11) were sedan
s based on the Nissan Primera
. Beginning with its third generation (V35), the Infiniti G have been rebadged versions
of the Nissan Skyline line of sedans and coupe
s that were exported to the United States and Canada. The current incarnation is the fourth generation (V36) which introduced the hardtop coupe convertible
. The Nissan FM platform
, on top of which the third and fourth generations (V35 and V36) of the Infiniti G have been built, also underpins the Nissan 370Z
and has shared components with the Infiniti M
, Infiniti EX
, and Infiniti FX
.
The Infiniti G20 was Infiniti
's entry-level luxury car in the United States during most of the 1990s and into the 2000s. Similar to the Japanese/European market Nissan Primera sedan, the G20 offered higher levels of standard equipment. It was launched in 1991 as Infiniti's first small car as an entry-level alternative to the Q45; later advertisements emphasized its European heritage with the tag line "Born in Japan. Educated in Europe. Now Available in America." Two generations of the G20 exist in the United States, the HP10 (P10), built from 1991 to 1996, and the HP11 (P11), built from 1999 to 2002. All G20s were front-wheel drive
and were built in Oppama
, Japan.
The first 1991 G20 was completed on July 10, 1990. The final 1996 G20 was completed on July 19, 1996. The P10 featured the first application of Nissan's multi-link front suspension in a front-wheel-drive car, with an independent MacPherson strut
setup in the rear. It came standard with a 5-speed manual transmission
. The only options to begin with were an automatic transmission
, leather interior, and a power glass moonroof; a Touring package (labeled G20t) was introduced in 1994 and featured a black leather interior with sport front bucket seats and fold-down rear seats, as well as a limited-slip differential in the transmission and a spoiler
on the rear decklid.
. It was a transversely
mounted dual overhead cam naturally aspirated
reciprocating
internal combustion engine
. Displacement was 2.0 litre (1998 cc) with a square (Bore × Stroke: 86.0 × 86.0 mm). This engine was also shared with the US-spec Nissan Sentra
/Nissan 200SX
SE-R, Nissan NX
2000, and a host of non-US Nissan vehicles. The particular version used in the G20 produced 140 hp crank in the US at first, and 145 hp in '00+ editions (116 to 126 whp; stock range) and 132 lbft or 136 lbft torque
(111 to 120 wft·lbf
; stock range). These engines were also fairly high-revving with a redline
of 7500 rpm for 1991 through 1996 editions, 6950 rpm for the 1999 edition, and 6750 rpm for 2000+ editions. Due to the SR20DE engine's flexibility, reliability, fuel economy and high power-handling capabilities, as well as a low buy-in cost, pre-owned NX2000, SE-R powered Sentras/200SXs and G20s have become popular and prominent in the "tuner" or "import scene
" subculture.
There were three major variants of the SR20DE used in the G20. The first, used from 1991 to 1993.5, was the highport, in which the injectors and fuel rail were located above the intake plenum. In 1994, due to tightening emissions restrictions, Nissan switched to a lowport design, in which the injectors and fuel rail switched places with the intake plenum. This design also featured a milder intake camshaft
. (Switching it out for the highport intake cam is a popular upgrade to gain more power.) This design was used from 1994 to 1996 and again in 1999. In 2000 Nissan replaced the valvetrain
with a roller-rocker arm lifter design in place of the (non roller) rocker arm previously used, but kept the lowport intake design; many performance parts are not interchangeable between roller-rocker and highport/lowport engines, most notably camshafts.
transmission
or an optional 4-speed automatic. Stock manual transmissions are typically usable up to approximately 250 whp, while stock automatic transmissions can only handle about 155 whp. Most front wheel drive transmissions from other SR-powered cars can be used with few modifications. The stock transmission as well as other SR20 transmissions are often upgraded with various modifications in order to handle more power. Common manual transmission
modifications include cryo treating, shot peening
, transmission case welding
, aftermarket limited slip differential
, aftermarket axle
s, and upgraded clutch
es. Common automatic transmission modifications include built valve bodies, aftermarket torque converter
s, automatic transmission fluid
(ATF) coolers, additional ATF filters, and aftermarket TCU
s. Higher rated transmission swaps from front-wheel drive VQ
or QR25DE powered cars such as the 2002–2006 Nissan Sentra SE-R Spec-V have also been performed.
version of the Nissan Primera, but because Infiniti was pitched as a premium brand, it featured a high level of equipment compared to its European and Japanese relatives. The only engine available was the 2.0 litre SR20DE Inline 4-cylinder
; in Europe this was the top-of-the-line engine for the Primera lineup. 5-speed manual and 4-speed automatic transmissions were both available, with the 5-speed being praised as "one of the best in the business." Power windows, power locks, power mirrors, air conditioning, four-wheel disc brakes with ABS
, alloy wheels, a Bose stereo, a theft-deterrent system
, cruise control
, floor mats, and a leather-wrapped steering wheel and gearshift knob were all standard. Heated mirrors, leather seats and a power moonroof were common options, and were later offered in a package that included power seats and keyless entry. Later models also featured dual front airbags. The standard trim was called Luxury. Two major trim package upgrades were offered: Touring, badged G20t, available from model years 1994 to 1996 and 1999 to 2001, and Sport (with no badge modification) which was offered during model year 2002. These packages featured a limited-slip differential in the transmission, sportier, more highly bolstered front bucket seats and fold-down rear seats, fog lamps, and a spoiler on the rear decklid. The details of these trims varied from year to year.
s replaced motorized seatbelts, leather interiors came standard with power front seats, matte-black side moldings replaced body-colored ones, the refrigerant
was converted from R12
to R134a, the audio system was upgraded to six speakers with a CD player instead of the previously-standard cassette deck, and other new options such as remote keyless entry were added. In addition, the 1994 model year was given a new larger chrome-plated
grille and door handles, a lowport engine (replacing the original highport SR20DE, in which the intake plenum is below the fuel injectors and fuel rail), a change in the vehicle's self-diagnostic system to OBD
-II, and larger 195/65R14 tires. The Touring models, introduced in 1994, featured a limited-slip differential in the transmission; 195/60R14 tires, sportier, more highly bolstered black leather front bucket seats and fold-down rear seats; fog lights; and a spoiler on the rear decklid.
The G20 was temporarily discontinued after the 1996 model year, leaving the I30 as Infiniti's lowest-priced car for the 1997 & 1998 model years.
The second-generation G20 underwent several changes, including adopting the multi-link
beam
rear suspension very similar to the 1995–1999 Nissan Maxima
with a continued use of the independent multi-link strut front suspension of the P10 (similar to the 300ZX
and Skyline GT-R). Despite enthusiasts' aversion to the beam, several publications praised the handling of the updated G20, as a technically good method of avoiding lateral suspension movement (which would compromise handling) while still offering a compliant ride. The P11 has a lateral grip figure of between 0.80 and 0.94g plus a 61/39 weight distribution
(61% front/39% rear). It grew in size, with a 2.7 inches (68.6 mm) length increase and 0.4 inches (10.2 mm) height increase over the P10, resulting in 1.4 inches (35.6 mm) more legroom for rear-seat passengers. The new model's increased size and luxury options, however, added to the car's weight (which rose to 3000 pounds); the stock 140-145 crank horsepower engine provided lower performance (the MY1999 automatic, for example, had a 10.9-second 0-60 mph time and did the quarter-mile in 18.4 seconds at 77 mi/h.
The first second-generation 1999 G20 was completed on May 18, 1998. The final second-generation 2002 G20 was completed on January 11, 2002. All models featured a higher level of standard equipment than the P10, including automatic climate control on all but cloth-seat Luxury models, 15" 16-spoke alloy wheels, a higher-quality double-DIN
Bose radio/CD/cassette player standard, keyless entry, standard power moonroof, and later, side-impact airbags. The Touring models continued to feature a limited-slip differential, but also had unique 12-spoke alloy wheels, and the upgraded sports seats were now available in beige leather and "sport cloth" (the latter as a factory-order option) in addition to the previously-offered black leather.
variant of the SR20DE engine was implemented, newer automatic and manual transmission variations were introduced, anti-theft immobilizer circuitry was added, anti-glare side mirrors became standard, and a remote trunk release was added to the keyless entry fob. In 2002, the G20t was dropped and a Sport model was introduced. In addition to the prior G20t's limited slip differential and decklid spoiler, this model featured two-tone leather/suede sport seats, 16" wheels, and a variety of minor cosmetic modifications. The 2002 base G20 received the 12-spoke Touring alloy wheels as standard.
of $23,000. The G35, significantly larger and more powerful than the G20, was aimed more at the entry level luxury-sports sedan
market instead of the G20's luxury-sport compact
market. The Nissan Primera was continued outside the United States as the slightly restyled HP11-144 and the significantly restyled HP12 markets with a final end to all production in 2006 as a 2007 model.
The third generation G (V35) was introduced to North America for the 2003 model year
, as the G35. It had little in common with the Infiniti G20, and continued in the same tradition as the Infiniti J30, which was also a RWD sedan utilizing the same powerplant as its contemporary Nissan Z model, the Nissan 300ZX
. According to Carlos Ghosn
, CEO of Nissan Motors
, the letter G was chosen "for marketing purposes and its similarity in sound to the letter J", apparently in deference to the Infiniti J30.
shared with the Nissan 350Z coupe and roadster
sports car
and Infiniti FX
crossover SUV
. The FM platform stands for "front midship" design where the engine is moved back towards the rear of the engine bay which in turn improves the weight distribution. The G35 was Motor Trend
s Car of the Year
for 2003 and has been well-received by both the media and customers as a viable alternative to other luxury cars. The G35 was also nominated for the North American Car of the Year
award that year and was on the Car and Driver Ten Best list
for 2003 and 2004.
Sporting the ubiquitous VQ35DE engine, the Infiniti G35 uses a front-midship engine, rear-wheel drive layout (all-wheel drive is available for the G35x sedan) to achieve a 52% front/48% rear weight distribution
. Both body styles are available with either a 5-speed automatic or 6-speed manual transmission
, although the automatic is the only transmission available for the AWD sedan.
A 6-speed manual transmission
became available in 2003 as a 2003 model on the sedan (the coupe always had the option). For the 2003-04 model years, the V6
produced 195 kW and 350 newton metre of torque in the sedan, 210 kW and 365 newton metre in the coupe. In the 2005 and 2006 model years, those with automatic transmissions (both sedan and coupe) produced 210 kW and 365 newton metre of torque, while those with manual transmissions produced 222 kW and 350 newton metre of torque (again, both in sedan and coupe form). There is speculation that the output did not actually change, and that Infiniti was simply taking advantage of the outdated SAE standard of rating horsepower. The G35 is assembled in Tochigi, Tochigi
, Japan, and the first G35 was built on March 12, 2002 as a 2003 model.
The AWD model of the G35 sedan is called the G35x in the United States and the Angelax elsewhere. Although the automatic transmission
for the G35x is manufactured by Aisin-Warner, the AWD technology uses Nissan's proprietary ATTESA E-TS AWD system. The system will make the car 100% rear wheel drive when driving at a steady speed. When the driver uses the throttle to accelerate from a stop or constant speed, the AWD system can send up to 50% of torque
to the front wheels. When the car's speed becomes steady again, the drivetrain will return torque to the rear wheels. The AWD system will also transfer torque to the front wheels if the system detects loss of traction. The process is made by the system in a matter of milliseconds. This technology was first used in the 1989 Nissan Skyline GT-R
, and has since been used in subsequent Skylines, and other vehicles in Japan and overseas, including the Nissan Bluebird
, and Nissan Stagea
.
There are few differences between the 2003 & 2004 G35 coupes. Both '03 & '04 six-speed manual models had the option of Brembo brakes and the Performance Tire and Wheel Package. On the 2005 coupes, three new colors, 'Athens Blue', 'Lakeshore Slate', and 'Serengeti Sand', replaced 'Twilight Blue', 'Caribbean Blue', and 'Desert Platinum' respectively; also, Willow Cloth interior was removed, and Stone became available.
The G35 was refreshed inside and out in 2005. The interior was given sportier gauges with better backlighting and higher quality trim and knobs. Genuine aluminum trim replaces "tinted" interior trim, and the dash and center console layout were revised. Rosewood trim becomes available as a package on the 2005 models. MP3/WMA playback was added to the now standard 6 disc in-dash CD player, and the cassette player was removed. Brembo
brakes were removed for the 2005 and 2006 models, and the brakes were redesigned with larger discs and a different caliper design. This was partly in response to a number of complaints about the previous years' brakes, which included a class action lawsuit filed in California related to premature wear on 2003–2004 models. A sport-tuned suspension package was standard on all six-speed manual equipped models, which included a viscous limited slip differential
and the higher output VQ35DE "Rev-UP" engine. The 2006 models received minor updates. On the exterior there were new headlights, taillights, spoiler, sport side sills, and front bumper. Bluetooth
capability was added to the interior for hands-free phone use. Rear active steering was an option for the '06 coupe.
redesigned the G sedan and coupe for the 2007 and 2008 model years, respectively. The fourth generation G sedan launched in November 2006 as a 2007 model with a heavily revised 3.5 L VQ35HR
engine and a 5-speed automatic as the standard transmission, a 6-speed manual was also available. The redesigned second generation G coupe launched in August 2007 as a 2008 model with a larger 3.7 L VQ37VHR, the first Infiniti
engine to feature VVEL. It too came with either a 5-speed automatic or 6-speed manual. All manual G models include a sport package. The 2009 model convertible G37 launched in June 2009. The 2009 model G sedan followed suit using the same VQ37VHR engine. Also for 2009 the 5-speed automatic was replaced with an all-new 7-speed and both the sedan and coupe gained a self-healing paint finish from the EX 35
. The V36 platform continued for 2010 with numerous interior changes and upgrades as well as a mid-product cycle exterior update for the sedan. In late 2010 the Infiniti G25 went on sale as a 2011 model, featuring a smaller 2.5L version of the VQVHR engine to allow the G to better compete with the Lexus IS250 and BMW 328i.
E-TS all-wheel drive system.
Along with these chassis refinements sport package equipped models get firmer rear shocks, bigger front brake calipers, and larger 13 inches (330.2 mm) rotors all around (up from 12.6/12.1-inch front/rear). Sport package equipped cars also get a viscous limited slip differential
. An all-new Active Steering
package can be ordered for sport package equipped models. It features a planetary gearset on the steering shaft (similar to BMW), that varies the steering ratio between 12.0:1 and 18.5:1. A rear-wheel steering system that induces up to one degree of rear steer is also included in this package. The Active Steering package includes even stiffer shocks than the sport package at all four corners and the ride has been repeatedly reported as being too stiff for most customers except the most "enthusiastic" drivers. Base and Journey model 17 inches (431.8 mm) tires bump up from 215s to 225s, while the 18 inches (457.2 mm) upgrade (included in sport or wheel package) with 225/50-ZR18 front and 245/45-ZR18 rear is now a size smaller in front and larger in back than the 1st gen model's all-around 235/45R18s.
The updated VQ35HR is more powerful (306 hp at 6,800 rpm and 268 ft.lbf at 4,800 rpm), more fuel efficient, and more responsive than the previous VQ35DE
. The "HR" stands for "High Revolution" or "High Response". A dual-path intake (two air cleaners, throttle bodies, etc.) lowers intake tract restriction by 18 percent and new equal-length exhaust manifolds lead into mufflers that are 25 percent freer flowing. The intake is said to benefit from a ram-air effect adding three horsepower at 60 mph. Electrically actuated variable valve timing
is new on the exhaust cams which broadens the torque curve. The new engine block maintains the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. 80% of the internal components have been strengthened or redesigned to handle the increased 7,500 rpm red line, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle. With an increase in compression ratio from 10.3:1 to 10.6:1 these changes add 26 more horsepower. Torque is down 2 ft.lbf from the old DE engine (268 vs. 270). The engine now sits 15 mm lower in the chassis for a lower center of gravity.
Although the horsepower rating increases only 8 hp compared to the latest version of the previous "DE" engine, the real horsepower difference was much greater due to Nissan adopting the 2006 SAE hp measurement guidelines for horsepower ratings in 2007. According to Consumer Reports an Infiniti G35 Journey sedan with a 5-speed Automatic transmission can reach 0–60 mph (0–96.6 km/h) in 5.4 seconds, and the 1/4 mile (~400 m) 13.8 seconds. According to the also newly revised EPA guidelines, fuel economy is estimated at 17 miles per US gallon in the city and 24 miles per US gallon on the highway. Fuel economy is virtually identical between generations, with the second generation earning a 1 miles per US gallon edge in highway driving (both measured using EPA 2008 guidelines).
Second generation G35 performance: According to Motor Trend
and Automobile Magazine
, a previous model 2005 G35 6MT sedan reached 0-60 mph in 5.7 seconds and the 1/4 mile in 14.1 seconds. This gives the new 2nd gen G35 V36 sedan a solid 0.4 and 0.3 second performance advantage respectively. Five Speed automatics are on par with manual transmission cars from a performance perspective. In a 2008 Road & Track comparison test with the new 2008 Cadillac CTS a 5-speed automatic transmission equipped G35 sedan achieved a 0-60 time of 5.3 seconds, a 0-100 time of 13.1 seconds and a 1/4 mile time of 13.8 seconds at 102.9 mi/h. Generally a V36 G35 reaches 60 mph in the low 5 second range; 100 mph in around 13 seconds and runs the quarter mile in about 13.8 seconds. The 200 lbs. heavier all wheel drive versions are only approx. 0.3 seconds behind in each of these measurements.
Models (including the since 2009 G37):
In addition, a special edition of the G37 was entered into the SEMA
Gran Turismo
Awards in 2008.
The vehicle was unveiled in 2006 North American International Auto Show.
In 2007, the redesigned G coupe was unveiled at the 2007 New York International Auto Show
and was available for sale as a 2008 model. Unlike the 2007 and 2008 G sedan it was given the new 3.7 L 330 hp V6
VQ37VHR engine but for this one model year still paired with the 5-speed automatic transmission and was named the "G37." In Japan, the G37 joined the updated G Sedan under the Nissan Skyline
(V36) nameplate. This also marks the first use of Nissan's VVEL (Variable Valve Event and Lift
) system on a production vehicle in the US market.
For the 2009 model the G35 sedan was replaced by the G37 sedan. The G37 sedan was first unveiled at the Geneva Motor Show for the European market. Exterior, interior and options remain identical to the 2008 G35 model range but the sedan now also sports the 3.7-liter VQ37VHR "VVEL" V6, rated 328 hp at 7,000 rpm and 269 ft.lbf at 5,200 rpm that was previously introduced in the G37 Coupe. Although the engine gains only 0.2 kg.m peak torque over the VQ35HR and this torque value arrives at a later 5,200 rpm vs. 4,800 in the VQ35HR, the torque curve itself is improved and flattened across the rpm range via Nissan's new VVEL (Variable Valve Event and Lift
) variable valve timing resulting in better throttle response and low rpm torque. The G37s VQ37VHR engine has been touted by car magazines and reviewers as an improvement over the VQ35HR engine mostly adding much more refinement and smoother engine operation, especially at high rpm where the VQ35HR engine was frequently criticized for NVH and sounding strained, harsh and loud. The often criticized too aggressive clutch engagement, notchiness of the 6-speed manual in the G35 and engine vibrations transferred through the shifter and pedals in the G35 6MT cars was also addressed in the new G37 models.
All 2009 models came standard with Infiniti's new 7-speed automatic transmission
that was also introduced on the 2009 FX35 and FX50. A much welcomed improvement over the previous 5-speed box. To equip the G37 Sedan or Coupe with a 6-speed manual transmission
the Sport 6MT model must be specified. Base, Journey and X models cannot be ordered with manual transmissions, however the Sport Package including all sport options of the 6MT model (except the manual transmission) can be added to the Journey and X models.
The 2009 sport package (standard on Sport 6MT cars, optional on Journey and X models) now also included larger sport brakes with 4-piston front/2-piston rear calipers with 14 inches (355.6 mm) ventilated front rotors and 13.8 inches (350.5 mm) ventilated rear rotors, a new sport wheel design 18 inches (457.2 mm) for the Sedan and 19 inches (482.6 mm) on the Coupe, and Viscous Limited-Slip Differential (VLSD). The Sport Package on G37 x AWD Sedans does not include the larger opposed piston brakes. Brakes on non Sport models are front 13 inches (330.2 mm) ventilated discs and rear 13 inches (330.2 mm) ventilated discs with sliding calipers. The G37 is available as G37, G37 Journey, G37S 6MT and G37x AWD models. Major option packages remain to be the Premium Package, Sport Package, Nav Package, Tech Package. All 2009 models come standard with self healing "Scratch Shield" paint which employs a soft polymer top coat that can self heal small scratches and swirl marks.
Even though the final drive ratio for vehicles equipped with the 7-speed automatic has been (numerically) reduced from 3.69 to 3.36, the new 7-speed automatic has much lower first through fourth gear overall ratios than the old 5-speed automatic and the 6-speed manual in the 6MT cars (which retain the old 3.69 final drive ratio). Giving it closer gear ratios in all gears, to match engine rpm better with power demand, brings better acceleration while overdrive ratios in 6th and 7th gears reduces highway cruising rpm and improves fuel mileage. The new 7-speed automatic retains the Drive Sport (DS) shift mode and Downshift Rev Matching (DRM) feature of the previous 5-speed automatic. Paddle shifters are standard on G37S models equipped with the 7-speed automatic. The new engine/transmission combo did add some weight the car (3,590 lb. for the G37 vs. 3,508 for the G35 in identical trim).
G37x Coupe uses an ATTESA
E-TS all-wheel drive system.
G37 coupe and sedan were set on sale in September 2008 as 2009 models.
G37x Coupe and G37 sedan were unveiled in 58th annual Pebble Beach Concours d'Elegance
. Pictures of G37 convertible was first shown in Monterey, while the vehicle itself would be unveiled in 2008 Los Angeles Auto Show in November.
The 2009 Infiniti G37 Anniversary Art Project Vehicle - This is a version of G37 Sport Coupe inspired by Cirque du Soleil
to commemorate Infiniti's 20th anniversary. The vehicle was designed by Montreal artist Heidi Taillefer. The vehicle was set on tour at various Cirque du Soleil shows and other events, with eventual vehicle sale at charity auction.
The G Convertible came equipped with a standard 325 hp 3.7-liter V6, backed by a choice of a 7-speed automatic transmission with available magnesium paddle shifters or a responsive close-ratio 6-speed manual transmission.
The Coupe received a refresh for the 2011 model year.
Priced lower than the G37, the G25 is aimed to compete with entry-level luxury rivals such as the Lexus IS
250 and BMW 328i
. Compared to the G37, other than a smaller engine and fewer options (no six-speed manual transmission available, no Navigation, no Premium or Technology packages in the U.S. market), the G25 is otherwise identical and features a choice of rear-wheel drive or ATTESA
all-wheel drive.
As a result of the G25 being the entry-level offering in the lineup, the 2011 G37 will be positioned more upmarket than the 2010 G37. In Canada, for the 2011 model year, the G25 and G37 Sport M6 are the only rear-wheel drive cars in the G lineup, with all other trims having all-wheel drive.

's entry-level luxury car in the United States during most of the 1990s and into the 2000s. Similar to the Japanese/European market Nissan Primera sedan, the G20 offered higher levels of standard equipment. It was launched in 1991 as Infiniti's first small car as an entry-level alternative to the Q45; later advertisements emphasized its European heritage with the tag line "Born in Japan. Educated in Europe. Now Available in America." Two generations of the G20 exist in the United States, the HP10 (P10), built from 1991 to 1996, and the HP11 (P11), built from 1999 to 2002.

There were three major variants of the SR20DE used in the G20. The first, used from 1991 to 1993.5, was the highport, in which the injectors and fuel rail were located above the intake plenum. In 1994, due to tightening emissions restrictions, Nissan switched to a lowport design, in which the injectors and fuel rail switched places with the intake plenum. This design also featured a milder intake camshaft

It grew in size, with a 2.7 inches (68.6 mm) length increase and 0.4 inches (10.2 mm) height increase over the P10, resulting in 1.4 inches (35.6 mm) more legroom for rear-seat passengers. The new model's increased size and luxury options, however, added to the car's weight (which rose to 3000 pounds); the stock 140-145 crank horsepower engine provided lower performance (the MY1999 automatic, for example, had a 10.9-second 0-60 mph time and did the quarter-mile in 18.4 seconds at 77 mi/h.

variant of the SR20DE engine was implemented, newer automatic and manual transmission variations were introduced, anti-theft immobilizer circuitry was added, anti-glare side mirrors became standard, and a remote trunk release was added to the keyless entry fob. In 2002, the G20t was dropped and a Sport model was introduced. In addition to the prior G20t's limited slip differential and decklid spoiler, this model featured two-tone leather/suede sport seats, 16" wheels, and a variety of minor cosmetic modifications. The 2002 base G20 received the 12-spoke Touring alloy wheels as standard.

brakes were removed for the 2005 and 2006 models, and the brakes were redesigned with larger discs and a different caliper design. This was partly in response to a number of complaints about the previous years' brakes, which included a class action lawsuit filed in California related to premature wear on 2003–2004 models. A sport-tuned suspension package was standard on all six-speed manual equipped models, which included a viscous limited slip differential

The 2009 model G sedan followed suit using the same VQ37VHR engine. Also for 2009 the 5-speed automatic was replaced with an all-new 7-speed and both the sedan and coupe gained a self-healing paint finish from the EX 35

. The V36 platform continued for 2010 with numerous interior changes and upgrades as well as a mid-product cycle exterior update for the sedan. In late 2010 the Infiniti G25 went on sale as a 2011 model, featuring a smaller 2.5L version of the VQVHR engine to allow the G to better compete with the Lexus IS250 and BMW 328i.
2007–2008 G35 Sedan
The G35 sedan underwent a major revision for the 2007 model year. This 2nd generation front-mid (FM) platform underpinning the new G is shared in part with the Infiniti M and has several structural reinforcements around the engine and rear floor area. Along with three times more laser welding and 16 percent more spot welds than the old version, overall body stiffness was improved by 40 percent. Single-pivot lower control arms in front replace the 1st gen model's twin lower links. The G35x sedan uses an ATTESAATTESA

Along with these chassis refinements sport package equipped models get firmer rear shocks, bigger front brake calipers, and larger 13 inches (330.2 mm) rotors all around (up from 12.6/12.1-inch front/rear). Sport package equipped cars also get a viscous limited slip differential

package can be ordered for sport package equipped models. It features a planetary gearset on the steering shaft (similar to BMW), that varies the steering ratio between 12.0:1 and 18.5:1. A rear-wheel steering system that induces up to one degree of rear steer is also included in this package. The Active Steering package includes even stiffer shocks than the sport package at all four corners and the ride has been repeatedly reported as being too stiff for most customers except the most "enthusiastic" drivers. Base and Journey model 17 inches (431.8 mm) tires bump up from 215s to 225s, while the 18 inches (457.2 mm) upgrade (included in sport or wheel package) with 225/50-ZR18 front and 245/45-ZR18 rear is now a size smaller in front and larger in back than the 1st gen model's all-around 235/45R18s.

A dual-path intake (two air cleaners, throttle bodies, etc.) lowers intake tract restriction by 18 percent and new equal-length exhaust manifolds lead into mufflers that are 25 percent freer flowing.

is new on the exhaust cams which broadens the torque curve. The new engine block maintains the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. 80% of the internal components have been strengthened or redesigned to handle the increased 7,500 rpm red line, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle. With an increase in compression ratio from 10.3:1 to 10.6:1 these changes add 26 more horsepower. Torque is down 2 ft.lbf from the old DE engine (268 vs. 270). The engine now sits 15 mm lower in the chassis for a lower center of gravity.
Although the horsepower rating increases only 8 hp compared to the latest version of the previous "DE" engine, the real horsepower difference was much greater due to Nissan adopting the 2006 SAE hp measurement guidelines for horsepower ratings in 2007. According to Consumer Reports an Infiniti G35 Journey sedan with a 5-speed Automatic transmission can reach 0–60 mph (0–96.6 km/h) in 5.4 seconds, and the 1/4 mile (~400 m) 13.8 seconds. According to the also newly revised EPA guidelines, fuel economy is estimated at 17 miles per US gallon in the city and 24 miles per US gallon on the highway. Fuel economy is virtually identical between generations, with the second generation earning a 1 miles per US gallon edge in highway driving (both measured using EPA 2008 guidelines).

, a previous model 2005 G35 6MT sedan reached 0-60 mph in 5.7 seconds and the 1/4 mile in 14.1 seconds. This gives the new 2nd gen G35 V36 sedan a solid 0.4 and 0.3 second performance advantage respectively. Five Speed automatics are on par with manual transmission cars from a performance perspective. In a 2008 Road & Track comparison test with the new 2008 Cadillac CTS a 5-speed automatic transmission equipped G35 sedan achieved a 0-60 time of 5.3 seconds, a 0-100 time of 13.1 seconds and a 1/4 mile time of 13.8 seconds at 102.9 mi/h. Generally a V36 G35 reaches 60 mph in the low 5 second range; 100 mph in around 13 seconds and runs the quarter mile in about 13.8 seconds. The 200 lbs. heavier all wheel drive versions are only approx. 0.3 seconds behind in each of these measurements.

) variable valve timing resulting in better throttle response and low rpm torque. The G37s VQ37VHR engine has been touted by car magazines and reviewers as an improvement over the VQ35HR engine mostly adding much more refinement and smoother engine operation, especially at high rpm where the VQ35HR engine was frequently criticized for NVH and sounding strained, harsh and loud. The often criticized too aggressive clutch engagement, notchiness of the 6-speed manual in the G35 and engine vibrations transferred through the shifter and pedals in the G35 6MT cars was also addressed in the new G37 models.

the Sport 6MT model must be specified. Base, Journey and X models cannot be ordered with manual transmissions, however the Sport Package including all sport options of the 6MT model (except the manual transmission) can be added to the Journey and X models.
The 2009 sport package (standard on Sport 6MT cars, optional on Journey and X models) now also included larger sport brakes with 4-piston front/2-piston rear calipers with 14 inches (355.6 mm) ventilated front rotors and 13.8 inches (350.5 mm) ventilated rear rotors, a new sport wheel design 18 inches (457.2 mm) for the Sedan and 19 inches (482.6 mm) on the Coupe, and Viscous Limited-Slip Differential (VLSD). The Sport Package on G37 x AWD Sedans does not include the larger opposed piston brakes. Brakes on non Sport models are front 13 inches (330.2 mm) ventilated discs and rear 13 inches (330.2 mm) ventilated discs with sliding calipers. The G37 is available as G37, G37 Journey, G37S 6MT and G37x AWD models. Major option packages remain to be the Premium Package, Sport Package, Nav Package, Tech Package. All 2009 models come standard with self healing "Scratch Shield" paint which employs a soft polymer top coat that can self heal small scratches and swirl marks.
Even though the final drive ratio for vehicles equipped with the 7-speed automatic has been (numerically) reduced from 3.69 to 3.36, the new 7-speed automatic has much lower first through fourth gear overall ratios than the old 5-speed automatic and the 6-speed manual in the 6MT cars (which retain the old 3.69 final drive ratio). Giving it closer gear ratios in all gears, to match engine rpm better with power demand, brings better acceleration while overdrive ratios in 6th and 7th gears reduces highway cruising rpm and improves fuel mileage. The new 7-speed automatic retains the Drive Sport (DS) shift mode and Downshift Rev Matching (DRM) feature of the previous 5-speed automatic. Paddle shifters are standard on G37S models equipped with the 7-speed automatic. The new engine/transmission combo did add some weight the car (3,590 lb. for the G37 vs. 3,508 for the G35 in identical trim).
