Encyclopedia
The Chevrolet Tahoe are full-size SUV
s from General Motors
. Chevrolet
and GMC
sold two different-sized SUVs under their Blazer/Jimmy
model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1992. Chevrolet
waited until 1994's introduction of a four-door version to rebadge the mid-size S-10 Blazer
as the Blazer
, renaming the full-size Blazer as the Tahoe.
The Chevrolet Tahoe and GMC Yukon currently serve as General Motors' full-size SUVs. Lengthened wheelbase models are available for both as the Suburban
for the Tahoe and Yukon XL
for the Yukon. A luxury Denali model joined the Yukon lineup in 1998. As of 2002, a Denali
version of the Yukon XL was also available as the Yukon XL Denali.
The new GMC Yukon was introduced for 1992, while Chevrolet
continued calling their version the Blazer. All were 2-door models through 1994. In 1995 the Chevy changed the name of the Blazer to Tahoe and introduced a 4-door version. The Tahoe was Motor Trend
magazine's Truck of the Year
for 1996.
The Tahoe/Yukon were shorter than the Suburban
on which they were based, but shared that vehicle's GMT400
platform
. This was a true truck chassis, and was based on that used in the Chevrolet Silverado
full-size pickup truck
. Both two-door and four-door models were produced, as well as rear- and four-wheel drive
.
The two door weighs roughly 4500 pounds while the four door weighs approximately 5500 pounds.
"AutoTrac" full-time all-wheel drive and a programmable Homelink transmitter were added for 1998. The upscale Denali trim line to the Yukon appeared around this time as the vehicles became popular with wealthy families.
The standard engine was Chevrolet's 350 cu in (5.7 l) LO5 small-block V8, while a turbocharged 395 cu in (6.5 l) Detroit Diesel V8 was available beginning in 1994.
In Mexico
, the Tahoe 2-door was released in 1995, called the Chevrolet Silverado, and in 1998 the 4-door was released as the Silverado 4-door, and both were available in Base, LS and luxury LT trim lines.
In Venezuela
, the Tahoe 2-door was released in 1993 (Only 4WD), called the Chevrolet Grand Blazer, and in 1996 the 4-door was released as the Grand Blazer 4-door (2WD). In 1996 the 2 Doors was discontinued. In 1996 only Grand Blazer 4-doors 4WD is available.
In Bolivia
, 1995 the 4-door was released as the Tahoe 4-door (4WD) build in USA.
Beginning in 1994, GM began making numerous annual changes to the Blazer/Yukon, including:
When the GMT800 platform based Chevrolet Tahoe/GMC Yukon was released for the 2000 model year, a 2WD Tahoe Limited and 4WD Tahoe Z71 remained in production on the GMT400 platform as special edition vehicles. These special edition vehicles were produced in the Arlington, Texas assembly plant for the 2000 model year only.
The Chevrolet Tahoe Limited was based on the Chevrolet Tahoe SS concept vehicle introduced in 1996 that never made it to production. It is reported that GM disliked the idea of an SS badged vehicle at a time when insurance companies were already demanding higher premiums for SUVs. The Tahoe SS prototype vehicles made in 1996 were painted either an unspecified metallic green or metallic blue, but the Tahoe Limited was produced only in black onyx metallic. The Tahoe Limited had a distinctive exterior appearance that included a factory equipped ground effects, a monochromatic theme with bumpers and grille painted in the same high gloss black as the body, removal of the roof rack, and fog lamps integrated into the front bumper. Other notable features of the Tahoe Limited included the Z60 high performance chassis package (commonly known as the police package) which places the body of the vehicle 2 inches lower than the 4WD Tahoe, two tone gray and charcoal leather interior seating surfaces, a 120 mi/h gauge cluster, 46mm Bilstein shock absorbers, a 3.42 or optional 3.73 rear gear ratio, a limited slip rear differential, an engine oil cooling system, and distinctive 16 inch Ronal R36 five spoke aluminum wheels.
The Chevrolet Tahoe Z71 also exhibited a monochromatic appearance similar to the Tahoe Limited, but instead of black onyx metallic the Tahoe Z71 was offered in either light pewter metallic, victory red, emerald green metallic, or indigo blue metallic. Features of the Tahoe Z71 were similar to those of the Tahoe Limited with a few key differences to distinguish the 2WD Tahoe Limited from the 4WD Tahoe Z71. Features that differ from those previously mentioned on the Tahoe Limited included the Z71 off road chassis package, two tone leather seating surfaces in either a gray or neutral theme, a standard 3.73 rear gear ratio, distinctive tail lamp lens covers, tubular side assist step bars, brush guard, body colored fender flares, and distinctive 16 inch Alcoa five spoke polished aluminum wheels.
The L31 5.7L Vortec V8 powerplant and 4L60E four speed automatic transmission shared with other GMT400 Chevrolet Tahoe vehicles were not modified in these special edition vehicles, and as such these special editions were mostly appearance packages.
on the new GMT800 platform, still shared with the full-sized pickups. Two new engines replaced the old 5.7 L (350ci) small-block V8, and while both were smaller, both produced more power. The manual transmission
was dropped, leaving only the automatic transmission
. In Mexico
, the GMT800 Chevy Tahoe is called a Chevrolet Sonora. A 2 door GMT800 Tahoe prototype was made but never entered production.
Both vehicles received significant updates with only the grille and headlights distinguishing one from the other. Both vehicles now featured softer lines as part of a more aerodynamic design. The interior was also updated with new seats, dashboard, and door panels.
"StabiliTrak" stability control was offered for the first time in 2003, as were XM Satellite Radio
, Bose audio, and a DVD
entertainment system as the models continued to climb upmarket. Both engines received 10 hp
(7.5 kW) more for 2004. It was the first generation of Tahoe, where the FlexFuel engine was available.
4800
[edit]LR4
The Vortec 4800 LR4 is a Generation III small block V8 truck engine. Displacement is 4.8 L (290 cu in) with a 96.01 mm (3.78 inch) bore and 83 mm (3.27 inch) stroke. It is the smallest of the Generation III Vortec truck engines and was the replacement for the 5.0 L 5000 L30. The LR4 produces 370 horsepower (280 kW) to 390 horsepower (290 kW) and 385 lbf·ft (522 N·m) to 405 lbf·ft (549 N·m), depending on the model year and application. LR4s are manufactured at St. Catharines, Ontario and Romulus, Michigan.

version of the Yukon, which uses the shared GM/Chrysler
Advanced Hybrid System 2, followed with the 2008 models. The GMT900 based Tahoe and Yukon exceeded initial sales expectations and continue to sell well despite a weakening market for large SUVs. For the first time, GM used the Tahoe name in Mexico
.
For 2007 the GMC Yukon and Chevrolet Tahoe received different front fascias and hood. The GMC Yukon features a monolithic grille and headlights, while the Chevrolet Tahoe grille is divided by a body colored bar similar to the chrome bar found on most GMT800 Tahoes. While the Tahoe's hood now features a design attribute obtruding from its otherwise smooth contour, the Yukon features a smooth hood with two slight curves on both sides of the hood. Both the new Yukon and Tahoe feature a more angular design that gives the vehicles a more upscale appearance. The interior was significantly redesigned as well. It features a new real wooded trim dashboard with new chrome accented instrument controls. New door panels as well as new seats were also added to the interior.
Short-wheelbase and police Tahoe production began at Arlington Assembly
on December 1, 2005. SWB Yukon production began in early 2006, with Janesville Assembly
coming on line as well. Long-wheelbase versions began at Janesville and Silao Assembly in March.
Highway mileage has improved from 19 mpg (12.4 L/100 km) to 21-22 mpg (11.2 L/100 km) with the addition of Active Fuel Management
cylinder deactivation. Both the old and new versions get 15-16 mpg (15.7 L/100 km) in town.
The 2007 Tahoe was featured on, and promoted through Donald Trump
's The Apprentice
, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored an online contest where entrants could create their own commercial for the new Tahoe.
For 2009, the 6.2 L engine in the Yukon Denali got a power increase to 403 hp, while a 395 hp 6.2 L was added as an option for the Tahoe LTZ. A 6-speed 6L80
automatic transmission replaced the 4-speed on all trucks except 2WD models with the 4.8 L engine.
2010 models underwent a mild mid-cycle refresh including a slightly raised bumper, revised door trim, improved side structure, and side torso air bags.
The Chevrolet Tahoe, GMC Yukon, and the Cadillac Escalade will be overhauled when the next-generation Chevrolet Silverado debuts, likely in 2013, and although rumours were the vehicles could go to monocoque crossovers, those were shelved, as General Motors plans to add to the traditional body-on-frame truck-based SUV, as the 2012 Chevrolet Colorado
-based Trailblazer
is debuting in 2013 for international markets, and the Colorado debuting in 2013 for North America, and truck owners wanting a smaller truck-based SUV, instead of the monocoque crossover.
nameplate started as the luxury version of the Yukon for the 1998 model year. The Denali trim is as in the GMC Envoy
available on both standard and XL versions.
In 1998, at the time of its introduction, the Yukon Denali was GM's answer to the Lincoln Navigator
, but then GM introduced a clone to the Yukon Denali and rebadged it "Escalade" under the Cadillac nameplate. The Yukon Denali's exterior was shared with the Cadillac Escalade
, with the entire front clip and lower side body panels differing from the standard Yukon. In the interior, however, the Denali features luxury options not available in the Yukon. These included an upgraded leather interior, power seats, heated seats front and rear, Bose stereo system, and some woodgrain on the dashboard.
Even though the Yukon was redesigned alongside the Chevrolet Suburban
and Tahoe in 2000, the Denali and Escalade
retained their 1990s base design. It was not until 2001 that the Denali and Escalade were redesigned. While the Escalade
departed from its Yukon based exterior design scheme in attempt to hide its roots, the Yukon Denali's exterior is almost the same as that of a post-2000 GMT400 model year Yukon. Embossed side body panels and slightly reworked headlights with projector-beam lenses along with 17" polished wheels and different grille and front bumper differentiate the Yukon Denali from the regular Yukon. 2001 also saw the introduction of the billet grille which now has become the hallmark of the Denali nameplate.

The Chevrolet Tahoe Hybrid uses a combination of its dual displacement 3.0/6.0-liter V8 engine and two 60 kW (continuous) electric motors that charge a 300-volt nickel-metal hydride battery. The vehicle can run on either gasoline, electricity or a mixture of the two using automatic Two-Mode Hybrid system that monitors the vehicle's torque, and state of the battery to choose the most efficient source of power. The battery is charged either directly by generating electricity through driving one or both electric motors using the gasoline engine (while the vehicle is coasting or being driven by the gasoline engine), or by the wheels driving one or both electric motors through what is called "Regenerative braking" when the vehicle is decelerating, thus regaining some of the energy invested in forward momentum. The Tahoe is considered a strong or full hybrid, in that it can run entirely on the battery (for a limited range) at low speeds. In city driving, the EPA
rating of fuel consumption for the 2WD version of the hybrid is 21 miles per US gallon. In comparison, non-hybrid varieties of the Tahoe are rated no higher than 15 mpg in city driving. In highway driving, the EPA rating is 22 miles per US gallon.
, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored an online contest in which anyone could create a commercial for the new Tahoe by entering text captions into the provided video clips; the winner's ad would air on national television. This viral marketing campaign initially appeared to backfire however, when hundreds of environmentally conscious parodies flooded YouTube and Chevy's website critiquing the vehicle for its low gas mileage. Over 400 negative ads were created in total, however over 20,000 positive ads were created making the campaign, according to Chevrolet, a success, despite the negative media attention.
the Tahoe GMT400 was sold under the name of "Grand Blazer". The GMT400 is used by Brazilian elite police units, such as the BOPE (Batalhão de Operações Policiais Especiais) in Rio de Janeiro
and the ROTA (Rondas Ostensivas Tobias de Aguiar) and GATE (Grupo de Ações Taticas Especiais) in São Paulo
. It is also used by the São Paulo State Police and the Rio Grande do Sul
State Police. But as the cars grew old, the great majority of them were substituted, mainly by smaller Chevrolet Blazer
s, the only midsize SUV currently offered by GM in Brazil.
In North America
, the Tahoe is used by many law enforcement agencies, fire departments
, and EMS agencies
. Chevrolet currently offers two versions of the police package Tahoe; a four-wheel drive version and a two-wheel drive version.
Chevrolet refers to the four-wheel drive (4WD) version as "Special Service Vehicle" (SSV). This version of the Tahoe can be used for all purposes except pursuits and high speed responses due to its high center of gravity, thus having a higher probability of rolling-over at high speeds. This version is preferred by agencies where snow, ice, flooding, rough terrain, and ground clearance are common issues.
Chevrolet refers to the two-wheel drive (2WD) version - also known as the rear-wheel drive (RWD) version - as "Police Pursuit Vehicle" (PPV). This version of the Tahoe can be used for all purposes including pursuits and high speed responses. The center of gravity in this vehicle is lower than that of the four-wheel drive version and the ground clearance is about one inch less. Highway patrol
agencies prefer the two-wheel drive version, where pursuits and long distance responses are more common. It should be noted that the two-wheel drive version of the Tahoe is the only pursuit-rated SUV on the market today.

For 2007 the GMC Yukon and Chevrolet Tahoe received different front fascias and hood. The GMC Yukon features a monolithic grille and headlights, while the Chevrolet Tahoe grille is divided by a body colored bar similar to the chrome bar found on most GMT800 Tahoes. While the Tahoe's hood now features a design attribute obtruding from its otherwise smooth contour, the Yukon features a smooth hood with two slight curves on both sides of the hood. Both the new Yukon and Tahoe feature a more angular design that gives the vehicles a more upscale appearance. The interior was significantly redesigned as well. It features a new real wooded trim dashboard with new chrome accented instrument controls. New door panels as well as new seats were also added to the interior.

departed from its Yukon based exterior design scheme in attempt to hide its roots, the Yukon Denali's exterior is almost the same as that of a post-2000 GMT400 model year Yukon. Embossed side body panels and slightly reworked headlights with projector-beam lenses along with 17" polished wheels and different grille and front bumper differentiate the Yukon Denali from the regular Yukon. 2001 also saw the introduction of the billet grille which now has become the hallmark of the Denali nameplate.
2007
The Yukon Denali was redesigned for the 2007 model year alongside the regular mainstream Yukon. The biggest change was in the styling, such as the flattened tailgate reminiscent of the new Tahoe, and particularly the grill and headlight shapes, which made the Yukon look less aggressive than previous models. The only exterior difference between the Yukon Denali and the standard Yukon are the chrome grille and extensive use of chrome accents; and of course the insignias, embeveled rockerpanels, chromed headlights and the Vortec 6200 engine which it shares with the Cadillac EscaladeCadillac Escalade

The Chevrolet Tahoe Hybrid uses a combination of its dual displacement 3.0/6.0-liter V8 engine and two 60 kW (continuous) electric motors that charge a 300-volt nickel-metal hydride battery. The vehicle can run on either gasoline, electricity or a mixture of the two using automatic Two-Mode Hybrid system that monitors the vehicle's torque, and state of the battery to choose the most efficient source of power. The battery is charged either directly by generating electricity through driving one or both electric motors using the gasoline engine (while the vehicle is coasting or being driven by the gasoline engine), or by the wheels driving one or both electric motors through what is called "Regenerative braking" when the vehicle is decelerating, thus regaining some of the energy invested in forward momentum. The Tahoe is considered a strong or full hybrid, in that it can run entirely on the battery (for a limited range) at low speeds. In city driving, the EPA

, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored an online contest in which anyone could create a commercial for the new Tahoe by entering text captions into the provided video clips; the winner's ad would air on national television. This viral marketing campaign initially appeared to backfire however, when hundreds of environmentally conscious parodies flooded YouTube and Chevy's website critiquing the vehicle for its low gas mileage. Over 400 negative ads were created in total, however over 20,000 positive ads were created making the campaign, according to Chevrolet, a success, despite the negative media attention.

. Chevrolet currently offers two versions of the police package Tahoe; a four-wheel drive version and a two-wheel drive version.
Chevrolet refers to the four-wheel drive (4WD) version as "Special Service Vehicle" (SSV). This version of the Tahoe can be used for all purposes except pursuits and high speed responses due to its high center of gravity, thus having a higher probability of rolling-over at high speeds. This version is preferred by agencies where snow, ice, flooding, rough terrain, and ground clearance are common issues.
Chevrolet refers to the two-wheel drive (2WD) version - also known as the rear-wheel drive (RWD) version - as "Police Pursuit Vehicle" (PPV). This version of the Tahoe can be used for all purposes including pursuits and high speed responses. The center of gravity in this vehicle is lower than that of the four-wheel drive version and the ground clearance is about one inch less. Highway patrol
