Porsche's 911 is venerable--is it also vulnerable? Like the Aston Martin V-8 Vantage, the aluminum-intensive, mid-engine R8 is designed to take on the 911. On sale in spring 2007 and based on the Le Mans quattro concept (shown), the R8 will come in many variations, launching with a 4.2-liter FSI V-8 and a 500-plus horsepower, 5.2-liter V-10 based on the Lamborghini Gallardo's engine (the R8 also uses the Lambo's basic chassis). A 280-horse, 3.6-liter V-6 bows for 2009 and T-top versions launch in 2010. Transmissions are six-speed manual for all, a six-speed DSG for the V-6, and an optional seven-speed DSG for V-8 and V-10 models.
Bottom line: Audi backs up its sports-car cred with a true 911-fighter.
