About Audi S4



The Audi S4 dates back to 1991 with the C4 platform, it was originally a spin off performance version of the Audi 100 which is now known as an Audi A4. The B5 chassis S4 was based off of the A4 with a powerful 2.7 liter biturbo version S4 model released in the US for 2000 to 2002. Aside from the impressive performance the exterior and interior styling was also enhanced to further set it apart from a standard A4. The B5 Audi S4 has larger rims, aluminum look mirror caps, updated bumpers and the interior featured S4 specific seats with more substantial side bolstering.A third generation B6 Audi S4 was released in North America for 2004 on an all new platform with an entirely different engine. Even though the platform was new for the third generation the highlight of the S4 was the highly talked about naturally aspirated 4.2 liter V8 engine producing a stout 340 horsepower and 302 ft lbs of torque. This was enough power to get the luxury sedan up to 60 mph in the 5 second range. The B7 S4 was available half way through the 2005 model year with some cosmetic changes along with minor revisions made to the suspension. The Bose sound system was made standard on the B7 S4 instead of having it be an option like it was on the Audi B6 S4.The all new B8 Audi S4 quattro wasnt available in the US until 2010, built on the VW Group MLB/MLP platform and based on the B8 A4 Quattro. This luxury sports car has a force induction 3.0 liter TFSI V6 engine with a roots style Eaton supercharger keeping power on tap with an advertised 333 hp. Many claim that the actual horsepower output is closer to 375 horsepower. This is enough power to propel the German luxury sedan to 60 in a sub 5 second range with a quarter mile run of high 12s. One of the most notable performance features would be the optional rear sport differential which greatly improves weight balance in corners and overall driving dynamics. It almost makes the S4 feel like it has 4 wheel steering because of the power transfer.
