The New Mercedes E63 AMG Will Be A 603bhp Twin-Turbo Monster

When we drove the latest Mercedes-AMG C63 in December of last year, we were blown away by its monstrous 4.0-litre, 469bhp turbocharged V8 engine. We even went so far as to call it the ‘super saloon king’, and as a result, we have high expectations for its bigger brother, the hotly-anticipated 2016 E63 AMG.

Now, thanks to a confidential two-page document - leaked on a German car forum - we know just how potent it’ll be. According to the brief document, the regular E63 will produce an impressive 563bhp and 553lb ft of torque from its AMG GT-sourced twin-turbo 4.0-litre V8 engine, giving the car a 0-62mph time of 3.7 seconds and a top speed of 155mph.

The S model, as expected, will receive a dose of extra power - 40bhp to be precise - giving the four-door saloon an ungodly 603bhp and 627lb ft of torque. The 0-62mph time is two tenths quicker than the standard model, and we expect that the S will be the most popular variant.

Both top speed numbers (see above) are adorned with asterisks, indicating that a performance pack with a raised limiter could be an option. Oh, and for those of you who will be ordering the faster car, you’ll be pleased to know that the fuel economy figure remains the same as the standard model, at a respectable 32.8mpg.

The document also suggests that the E63 will be the first ever AMG model to receive Mercedes’ nine-speed MCT automatic gearbox. We can’t wait to try the system, but it will have to be utterly brilliant to beat the ZF eight-speed gearbox that’s so popular at this end of the market.

Order books are expected to open after the big reveal at the Paris motor show.
