Smaller, turbocharged V8 set to replace today's mighty 6.2-litre unit.
Mercedes-Benz’s bellowing 6.2-litre V8 is on its last legs.
AMG’s head of development, Tobias Moers, has confirmed that the next-generation C63 AMG will be powered by a downsized turbocharged engine.
But, unlike its arch rival BMW’s upcoming new M3/M4, AMG won’t be reducing the number of cylinders with Moers adding that the top-secret powerplant will still retain its V8 configuration.
He would not divulge any more details, including whether it would adopt the 5.5-litre twin-turbo V8 that now powers the majority of the AMG range - including the E63, CLS63, ML63 and S63 - or if it will debut the 4.0-litre twin-turbo V8 that is reportedly under development.
“All I will say is that it will be a good engine,” he said with a wry smile.
“The 6.2-litre V8 is, as you can see, now only available in the C63 and SLS and we have turbocharged engines in most of our other cars. There is not a lot of room for speculation.”
Drive sources have indicated the new C63 AMG, which is due to debut in 2015 after the base model C-Class is revealed at the end of next year, will adopt a lot of the latest turbo technology AMG has developed for its A45 hot hatch, which produces benchmark outputs of 265kW and 400Nm.
That could indicate the 4.0-litre V8 may possibly be two four cylinders sharing the same crank, which provides massive potential for the 2014 C63 AMG to increase power outputs beyond the 373kW produced by today’s top-spec C63 AMG Edition 507 but with significant improvements in fuel consumption.
Although Moers admitted that all-wheel drive transmissions would play a more critical role in future AMG variants, following in the wheel tracks of the A45 and revised E63 which is available with Benz‘ 4Matic system in left-hand drive only, he confirmed the C63 AMG would remain a rear-driver only.
“C63 AMG is a more aggressive car,” he said.
“The competitive set is very clear with one direct rival [BMW M3/M4] and I think we have achieved a level of performance as our main competitor. It is a car where fun-to-drive is very important, so we don’t have any plans for 4Matic in this car today.”
