Audi A4 (Germany, 2008-present)

The fourth generation Audi A4, otherwise known as the B8, was first publicly seen in September 2007 at the Frankfurt Motor Show. Audi initially introduced the sedan model only and not until the Geneva Motor Show of March 2008 did the company release the ‘Avant’ wagon version.

The new model has slightly larger dimensions than its previous generation, which subsequently allows for more legroom in the backseat. Although larger, the B8 is actually lighter, given that its weight dropped around 10% from the previous model. The B8 A4 is currently in active production.

Petrol engines available are 1.8- and 2.0-liter units, plus a 3.2-liter V6, all with FSI (fuel stratified injection) system. The diesel engine range comprises a 2.0-liter TDI (turbocharged direct injection) and 2.7- or 3.0-liter V6 TDI engines. Power outputs available place between 118 hp and 261 hp for petrol engines, while going from 118 hp to 237 hp in the diesel engines. The fourth series A4 reaches its top speed at 155 mph (250 km/h).

This model can either come with front-wheel drive or ‘quattro’ permanent four-wheel drive system. The A4’s standard transmission is a 6-speed manual, but 6-speed ‘tiptronic’ automatic and 8-speed ‘multitronic’ CVT transmissions were also made available. In 2009 Audi added a new option for the European markets: a 7-speed dual-clutch ‘S-tronic’ transmission.
