No sources for the information are provided, although speculation is that AMG's signature twin-turbocharged 4.0-litre V8 petrol engine will return to the C63 and E63 – the latter possibly running an E Performance PHEV set-up with a rear-mounted electric motor and lithiummion battery similar to that used by the recently launched new 791bhp S63.
Autocar contacted AMG for comment on the report, but a spokesperson refused to be drawn into divulging any possible plans, saying: “We do not actively comment on speculation surrounding our business activities." Speculation surrounding AMG engine's plans has been rife since reports allegedly confirmed the Mercedes-Benz performance division wasn't planning a successor model to the E63.
The unsubstantiated reports, first aired in the German media, claimed the sole AMG model in the new E-Class line-up would be a six-cylinder E53. In an interview with AMG CEO Michael Schiebe in early July, Autocar was told the company planned to engineer its twin-turbocharged 4.0-litre V8 engine to comply with upcoming EU7 emission regulations.
