Perhaps it was part of a Christmas bonus for the employees, or a renegade draftsman who broke into his piggy bank in an act of selfless charity towards his fellow coworkers, but someone has gifted the designers in Ingolstadt a set of curved stencils. This is nowhere more evident than the seventh-generation of Audi’s B-chassis cars, first introduced to us as the mid-year 2005 A4 and now embodied in the 2006 S4 Wagon.
The Audi S4 is a sport version of the German automaker's entry level sedan powered by a 2.7 Liter Biturbo V6 that sent 251 HP and 258 lb-ft of torque through a Quattro all wheel drive system in 1997. In 2003 the S4 was redesigned with a few new bloated body lines and Audi placed a 4.2 Liter V8 making 339 HP and 302 lb-ft of torque under the hood that would accelerate the four door from 0 to 60 MPH in under 5 seconds. In 2005 the S4 became a bit more curvaceous but retained the same power plant. The latest generation S4 went on sale in 2008 and is powered by a smaller supercharged V6 that produces a more efficient 333 HP and can get to 60 MPH in 4.9 seconds.
The S4, a high-performance offshoot of the compact A4, rejoined Audi’s lineup for the 2004 model year. The S4 is powered by a 340-horsepower, 4.2-liter V-8 that teams with either a six-speed-manual gearbox or a six-speed-automatic transmission that incorporates a manual-shift provision.
