The upcoming 2015 Mercedes-Benz C63 AMG has been spied testing yet again and many of the visual changes can now be seen thanks to the absence of some camouflage.
At the rear in the spy shot you see above, a more aggressive bumper can be seen joined by AMGs aggressive rectangular quad exhaust pipes. These differ from those in the previous generation C63 AMG as they were rounded. This particular prototype may be riding on mismatched wheels but hiding behind them are cross-drilled discs along with golden calipers.
Under the hood, the new C63 AMG will receive a 4.0-liter twin-turbocharged V8 engine in favour of the naturally-aspirated 6.2-liter V8 currently used. This new engine will continue with Mercedes-Benzes introduction of smaller capacity engines and will eventually replace the current 5.5-liter twin-turbo. For those that didn’t know, the AMG 6.2-liter V8 engine has been largely phased out and replaced by the 5.5-liter powertrain.
Currently codenamed M177, the new 4.0-liter twin-turbo V8 is predicted to produce between 454 hp and 493 hp depending on the specification ordered. It will then be mated to the 7G-MCT SpeedShift automatic transmission currently used in a selection of other AMG models.
While it remains to be confirmed, a debut later this year is likely.
