2014 Mercedes-Benz C63 AMG Edition 507: First Look

• Competes with: BMW M3, Audi S4, Cadillac CTS-V
• Looks like: The family man's SLS AMG
• Drivetrain: 507-hp, 6.3-liter V-8; seven-speed automatic transmission; rear-wheel drive
• Hits dealerships: Late 2013

Perhaps you've considered the current Mercedes-Benz C63 AMG, the German uber sports coupe and sedan based off of Mercedes' C-Class and stuffed with a monster 6.3-liter V-8, but felt that its 451-horsepower rating was only just adequate. Well you're in luck: Mercedes-Benz just announced the new 2014 C63 AMG Edition 507, which takes the current car and miraculously boosts output by another 56 hp to a solid 507.

It's done by borrowing heavily from components that go into the fire-breathing SLS AMG gull-wing coupe, including the SLS engine's connecting rods, lightweight crankshaft, forged pistons and composite brake system. This drops the C63 AMG's zero-to-60 time from 4.4 seconds to 4.1 seconds and raises the car's top speed to 174 mph - but to get that top speed, one must attend a course at the AMG Driving Academy, which is included in the car's price.

Mercedes-Benz' New Turbo V-8 Engines

Today, Mercedes-Benz revealed more details about its V-8 engine lineup. The two new V-8 powertrains promise more power, improved emissions and better fuel efficiency.

The more important of the two is the new twin turbo 4.6-liter V-8. It will replace the successful 5.5-liter V-8 that powers most Mercedes with the “550” behind their class designations.

The engine’s decreased displacement is offset by the power boost of the twin turbochargers, which have a fairly high 10.5-to-1 compression ratio. The 4.6 promises 10 percent better fuel economy while producing 30% better torque. In the 2011 CL500, it produces 429 horsepower and 516 pounds-feet of torque. That’s 12% better power and 32% better torque than the outgoing 5.5-liter V-8 found in the 2010 CL550. This engine will likely find its way into the E-Class and the S-Class in the near future.

2008 Mercedes-Benz C63 AMG: A Really Fast C-Class

Just as Mercedes dealers are preparing for the arrival of the new C-Class in early August, we hear word of the car’s more powerful sibling, the C63 AMG. AMG is the designation the company gives to its most powerful models, just like BMW’s M and Audi’s S and RS designations. The C63 is so named because a 6.3-liter V-8 producing 457 hp is housed under its hood. 

That gets the new C63 to 62 mph in 4.5 seconds, though buyers will have to accept the fact that the C63 comes with a seven-speed automatic transmission with shift paddles on the steering wheel, not the standard — and often preferred — stick shift. There are three modes for adjustable shifting between Sport, Comfort and Manual. The Sport mode will shift gears 30% faster than Comfort mode and 50% faster than the default Manual mode.   

Enthusiast drivers will also appreciate an adjustable electronic stability system that can be turned off completely or set to Sport mode, which allows for safely pushing the car closer to its limits.

Of course, the C63 also has a beefed-up look to match its enhanced performance. The hood is larger, with two “power domes,” and both the front and rear bumpers are more aggressive than the standard C-Class. There are also available 19-inch wheels and standard 18-inchers. Inside, the seats are of the sport variety, and there’s even a different steering wheel aimed at enthusiast drivers. All this work should make the C63 formidable competition for the Audi RS4 and upcoming BMW M3. We won’t know for sure until early 2008, when the C63 will go on sale.
