Audi S4 B7
To compete with the C Class AMG and BMW M3, Audi introduced the S4, a compact four-door executive sedan or wagon with powerful engines. The first generation from the late 1990s was decent. However, when the third generation S4 was introduced in 2005, this car became independent from the rest of its German counterparts. The B7 generation was introduced in 2005 and immediately became one of the hottest four-door cars in the world. From the outside, Audi gave the S4 a stealth look with just a few minor details showing its true nature. On the inside, a perfectly designed interior, the finest leather, and loads of options created one of the best driver’s habitats in the industry. But all of that is secondary to the engine and drivetrain (via Car Throttle).
Hiding in the front is a 4.2-liter V8 engine with 344 hp and 302 lb.-ft of torque that sends all of its power to all four wheels through an intelligent AWD system. Buyers could choose between manual or automatic transmission. Regardless of the transmission choice, acceleration times are well below the five-second mark. With its understated looks and quality interior, the Audi S4 B7 produced from 2005 to 2008 is an ideal proposition for people looking for a German muscle car with a stealth package.
