Mercedes-Benz C63 AMG

Contrary to what most marketing tells us, progress is not always forward. Sometimes a product nails the balance of what consumers want so perfectly that it's nearly impossible to improve on it – just compare the original Ford Mustang to the atrocious Mustang 2. Drive's Chris Harris is worried the same fate is about to befall the Mercedes-Benz C63 AMG, which he reckons is at the top of the heap of German sport sedans.

The next-generation, AMG-tuned C-Class is rumored to use a 4.0-liter, turbocharged V8 with between 450 horsepower and 500 hp to replace the C63 AMG's legendary M156 6.2-liter V8 with 451 hp and 443 pound-feet of torque. Even Harris admits that the new engine will likely improve on the C63's dismal fuel economy, but he doesn't believe that it will drive any better. And if the E63 AMG's downsized M157 5.5-liter V8 engine is any indication, it certainly won't sound any better, either.
