Malfunctioning development car allows us to snap closer shots than ever; leaked info suggests the car will produce 603bhp from its twin-turbocharged V8 engine

A development mule for the 2016 Mercedes-AMG E 63 has been photographed broken down in Germany, offering us our most detailed look at the next-gen super saloon yet.

The test mule confirms the look of the upcoming E 63 will add muscle to the latest E-Class's exterior, but in a predictably subtle way. More aggressive bumpers and quad-exit exhausts are the biggest give away for the car's added potency, but much of the design is unchanged from the regular car.

Our photographers also snapped a picture of the car's dash, which uses the same digital display as the regular E-Class but with a speedo that reads up to 330kmh. No doubt the car's top speed will fall short of this number (which equates to 205mph), but it confirms some of the menus and infotainment pages will be bespoke to the AMG.

What caused this particular mule's break down has not been revealed, but the development drivers were able to re-start it after following instructions on the phone, suggesting it was a minor electrical or software issue.

Performance

The new pictures follow a leak on a German car forum from earlier this year, which revealed the performance figures of the upcoming super saloon months ahead of its global reveal.

When translated, the two-page document suggested the E 63 will produce 603bhp and 627lb ft of torque from its twin-turbo 4.0-litre V8 engine in S spec, while the regular E 63 will produce 563bhp and 553lb ft of torque. This backs up earlier claims that the engine (which is a wet-sumped version of the dry sump unit featured in the 510bhp AMG GT) would be capable of more than 600bhp, and ensures the 2016 model will be significantly more potent than the Audi RS6 and BMW M6, both of which currently produce 552bhp.

The leaked photos also reveal straight-line performance figures. The E 63 is claimed to be capable of accelerating from 0-62mph in 3.7sec; the E 63 S is two 10ths quicker. Both are limited to a 155mph top speed, although the asterix next to that figure suggests the new car will be available with a raised top speed, should owners want one. Both models share the same claim for a 32.8mpg combined fuel economy figure, too.

Mercedes has refrained from commenting on the leaked documents, nevertheless insiders are confident the information they contain is genuine.

It is thought that the new E 63 will be lighter than the outgoing version and will be the first AMG model to use the new nine-speed automatic transmission. This second claim is backed up the aforementioned leaked document, which mentions a nine-speed MCT gearbox. It also suggests Mercedes' air body control suspension will be included, which comes as no big surprise.

Four-wheel-drive only

AMG boss Tobias Moers has promised that these changes mean the car itself will be “not an evolution but a pure revolution - the biggest step an AMG E-Class has made”.

Speaking to Autocar, Moers revealed that the performance E-Class will be four-wheel-drive-only in all markets, but added: “Don’t worry - it will still do skids, drifts and all the stupid stuff we love.”

The car isn't due to be revealed until the Paris motor show in October, so the only images currently available have come from our spy photographers, who recently spotted a development E 63 testing in the Arctic Circle.

Order books are expected to open after the car's reveal, with first UK deliveries arriving at the start of 2017. BMW's rival model, the M5, will arrive later in 2017. That car is expected to stick with a rear-wheel-drive layout.

Our Verdict

Mercedes-Benz C-Class
The C-Class shares a lot of its looks with the new S-Class, furthering its desirability

Can our perennial runner-up in this class finally reach the top spot?

"It would be the first time that the super-saloon power war hit 600bhp for a standard production car."

I think Tesla got there before - and then blew through 750bhp for good measure.

M5 Competition & M6 now have the same engine tune from the 30 jahre special edition, which has 600BHP.
Tired of these in accuracies by Autocar, as long as its not a JLR product they don't seem to care about the articles and also their star ratings.

Let's not forget the Audi S8 Plus with over 600bhp too.

...the RS6 Performance, with 605 PS, and 553lbft in 'overboost'.

That is not more than 600bhp. 605ps = 596.8bhp.

The S8 Plus has 596bhp you idiot.

Looks like the horsepower arms race is back on then. Good luck achieving the claimed mpg, clearly not why you'd buy such a car but what conditions were they achieved in?

Also good to see the usual anti-JLR crowd have ticked the box with their comments.

....as claimed in the article, then why are they able to see anything on the digital dash?
