, 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.

rack in front of the axle also improves handling over previous A4 platforms.

The B8 A4 has increased in length by 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 longer wheelbase and longer length.

In Malaysia auto market, Audi A4 B8’s depreciation rate falls faster than Japanese Executive car equivalent, probably due to unconvincing after sales service.

In 2009, Audi announced the S Tronic transmission option for A4 in UK market.

The convertible model will not return. It is scheduled to be replaced by the A5/S5 cabriolet.

A4 allroad quattro

An allroad variant of the A4 Avant, similar to the Audi A6 allroad quattro, was announced by Audi in February 2009. This features a wider track, increased ground clearance, quattro permanent all-wheel drive, a distinctive radiator grille, stainless steel underbody guards and roof rails.
