Audi A4

Audi released the first official pictures of the B8 series A4 in August 2007, and unveiled the car to the public at the September 2007 Frankfurt Auto Show. Saloon/sedan and Avant (estate/wagon) models are offered. The Avant was unveiled to the public at the March 2008 Geneva Auto Show.

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 center 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 length by 117 mm (4.6 in) over the prior B7, which has allowed for increased rear seating legroom. Although the overall dimensions have increased, the curb 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 1,430 litres with the rear seats folded down.

A long wheelbase version called the A4L was launched for the China market in November 2008 with a 60 mm (2.4 in) longer wheelbase and 50 mm (2.0 in) longer length.
