Spy Shots: 2015 Mercedes-Benz C63 AMG Sports Sedan will Likely get Twin-Turbo V8

|

The go-faster crew at Mercedes-Benz's AMG division has its hands full these days with an army of new models including the BMW M3-rivaling C63 AMG edition of the upcoming W205 series that will replace the current C-Class.

The next C63 AMG, scheduled for a release within the next 18 months, was captured by our spy photographers running a few hot laps on the Nürburgring track. The camouflaged test car featured slightly wider fenders and bigger brakes than its lesser siblings.

We anticipate that the styling of the W205 C-Class series in general will draw heavily on the design of the larger W222 S-Class sedan that will be unveiled next year, with the AMG variant adding a muscular aero package and beefier wheels to the recipe.

Like the other C-Class models, the C63 AMG will be built around the brand's new MRA “Mercedes rear-wheel drive” architecture.

There are more changes to be found under the hood as according to sources, the German firm will replace the current models naturally aspirated 6.2-liter V8 (marketed as the "6.3" to commemorate the brand's first V8 engine that had a displacement of 6.3L), with a bi-turbocharged unit.

The new force-fed V8 will likely deliver the same output as the current model's V8 at 451Hp (457PS), but will make more torque from a lower engine speed, while also offering reduced C02 emissions and better fuel economy. An optional performance package as well as the limited Black Series Edition should push output closer to 500-ponies.
