Audi A4 B8
Encyclopedia
Audi A4 is the 4th generation of Audi A4
. The B8 A4 is built on a variant of the Audi Modular Longitudinal Platform
, a platform which is also used in the Audi A5
coupé
. Whilst prior A4 chassis were limited in wheelbase
due to the relationship between the engine
, transmission
and front axle
, the MLP allows for a reduced front overhang, resulting in a greater wheelbase length without the same increase in overall length. This effectively redistributes the centre of gravity slightly rearwards, improving handling by better balancing vehicle mass between the front and rear axles. The estimated static front:rear weight ratio of the B8 A4 is approximately 55:45, depending on body style and engine. The relocation of the steering
rack in front of the axle also improves handling over previous A4 platforms.
The B8 A4 has increased in wheelbase by 160 millimetres (6.3 in) and in length by 117 millimetres (4.6 in) over the prior B7, which has allowed for increased rear seating legroom. Although the overall dimensions have increased, the kerb weight has dropped some 10%. The boot (trunk) has also increased to 480 litres (17 cu ft) for the saloon (sedan) version. The A4 Avant will have a maximum capacity of 1430 l (50.5 cu ft) with the rear seats folded down.
Reception has been mixed, with praise for the Audi A4's increased size, giving it best-in-class rear legroom and trunk space in the compact executive car segment. Its inline-four 2.0 TSFI engine, while efficiently providing plenty of torque, was considered lacking and less refined compared to six-cylinder engines of lighter rivals who posted faster acceleration times. However, the Audi S4
has been well-received for its V6
3.0 TSFI engine's power and efficiency.

The quattro permanent four-wheel drive
system uses the latest Torsen
T-3 centre differential, with a default 40:60 front to rear asymmetric torque distribution ratio (used first on the B7 RS4) as standard. (Previous A4 quattro models split torque with a default front:rear 50:50). The additional torque bias applied to the rear wheels helps mimic the driving dynamics of rear wheel drive cars.
Audi was reported to stop offering 3.2L V6 models in 2010 model year, but still offers them as of August 2011 (Germany).

Safety
The Audi A4 (B8) passed the Euro NCAP crash tests, and was awarded the following car safety ratings:- AdultAdultAn adult is a human being or living organism that is of relatively mature age, typically associated with sexual maturity and the attainment of reproductive age....
occupant = - ChildChildBiologically, a child is generally a human between the stages of birth and puberty. Some vernacular definitions of a child include the fetus, as being an unborn child. The legal definition of "child" generally refers to a minor, otherwise known as a person younger than the age of majority...
occupant = - PedestrianPedestrianA pedestrian is a person traveling on foot, whether walking or running. In some communities, those traveling using roller skates or skateboards are also considered to be pedestrians. In modern times, the term mostly refers to someone walking on a road or footpath, but this was not the case...

A4 TDI concept e (2008)
It includes a common railCommon rail
Common rail direct fuel injection is a modern variant of direct fuel injection system for petrol and diesel engines.On diesel engines, it features a high-pressure fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding unit injectors...
1968 cc TDI diesel engine rated at 120 PS and 290 newton metre, a stop-start system
Start-stop system
In automobiles, a start-stop system or stop-start system automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby improving fuel economy and reducing emissions...
and regenerative braking
Regenerative brake
A regenerative brake is an energy recovery mechanism which slows a vehicle or object down by converting its kinetic energy into another form, which can be either used immediately or stored until needed...
. It can achieve a fuel consumption of 3.99L/100 km (58.95 mpg) and CO2 output of 105 g/km. It can accelerate 0-100 km/h (62.1 mph) in 10.7 seconds, with top speed of 206 km/h (128 mph).
Other features include electric motor
Electric motor
An electric motor converts electrical energy into mechanical energy.Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force...
-based power steering, revised aerodynamics
Aerodynamics
Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with...

Tire
A tire or tyre is a ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground...

Model year changes
During a model cycle changes are made to integrate new technologies and to keep the model competitive. These changes are referenced based on the model year (MY) of the car.In Australia, the B8 has undergone 2 revisions leading to three variants, the B8, B8 MY10 and B8 MY11.
