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. |
