The next generation S4 will be unveiled in 2009 as a 2010 model. The super-sedan will be powered by a supercharged 3.0-liter V6 and will have enough power to compete with models like BMW 335i.
In 2011 Audi will also unveil a RS4 version, powered by a V8 engine. It will compete with M3.
The 2010 S4 will loose weight and will have improved fuel economy.
