The facelift version of the Audi A4 is on sale in Europe and will go on sale in the USA in the summer of 2012. In this short time, the model has already received a number of significant upgrades, but German tuner, ABT Sportsline , is adding another one to the faster version of the A4, the S4. Their package, called the AS4, includes a series of exterior upgrades and some serious engine boosts to allow the A4 to excel.
The exterior changes were made to improve the car’s aerodynamics and were kept to a minimum. These changes include a new air dam, new side sills and wing inserts, aerofoils, rear apron inserts, a two-pipe exhaust system, and, of course, a new set of alloy wheels.
Under the hoods of the different versions of the A4, the most impressive changes were made for the S4 . The Audi S4’s 3.0 L TFSI V6 engine was pumped up to 435 HP from the standard 333 HP. The top speed limiter has also been removed, providing the luxury sedan with a top speed of 175 mph, while the 0 to 60 mph sprint is made in 4.8 seconds. The 3.0 TDI engine has also been increased from 245 HP to 282 HP, while the tiny four-cylinder version, the 2.0 TFSI, goes from 211 HP to 275 HP.
