Compared to earlier prototypes of the high-performance E63 sedan and new E-Class wagon, this car has shed some layers of disguise, with much of the doors, rear flanks and tailgate doing without the swirly camouflage that still adorns the sills, bumpers, rear windows, and the entire front end.
With the sedan already launched, the smooth styling of the E-Class wagon's hindquarters shouldn't be a surprise to anyone. For the first time, though, we can see the shape and the graphics of the wagon's tail-lights, which, in the E63 at least, utilises LEDs for the indicators and brake lights.
Up front, the E63 sports a large single-bar grille, and very amply-sized lower air intakes. The E63's brake discs are of the cross-drilled variety and are clamped by can't-miss-'em red callipers. Out the back, four rectangular exhaust tips hint at the wagon's performance potential.
Under the bonnet, the E63 sedan and wagon will ditch the current car's 5.5-litre V8 in favour of AMG's 4.0-litre twin-turbo V8, which also powers the Mercedes-AMG GT coupe, and the C63 and C63 S.
If a Russian dealer brochure leaked in April is accurate, the E63 and E63 S will feature the most powerful versions of the engine yet.
The alleged 420kW/750Nm motor in the E63 can propel the sedan from 0-100km/h in under 3.7 seconds and on to an electronically limited top speed of 250km/h.
For those whom too much isn't quite enough, the E63 S will have an even more fiery 450kW/850Nm version of the 4.0-litre V8. In the sedan, the 0-100km/h time is reportedly reduced to 3.5 seconds. The electronically limited top speed is unchanged at 250km/h.
The Mercedes-AMG E63 sedan is expected to debut at the Paris motor show, which takes place at the beginning of October. The wagon is likely to surface a few months later.
An Australian debut for the new E63 sedan will probably take place in the first half of 2017. The wagon should follow in the second half of the year.
