Spied on several occasions now, here are more photos of the coming Mercedes-AMG E 63 test mule. As before, our spy photographers say that this unit has also been spied in Spain, under very different weather conditions this time.

While the E63 here maintains the same level of camouflage as before, this is probably the closest photographers have ever gotten to the car. Finer details of the new E 63’s unique items are visible, such as the large air intakes on the AMG-specific front bumper, grille and AMG-badged quad exhaust tips at the rear.

Also visible in close detail are the new headlights and tail lights from the latest-gen W213 E-Class, a set of 19-inch multi-spoke AMG wheels wrapped in Michelin Pilot Alpin (winter) rubbers and perforated disc brakes with gold calipers at the front and rear.

For power, the next-gen E 63 will feature the same 4.0 litre biturbo V8 engine from the C 63 and AMG GT. However, the M178’s application here could be in the most powerful state we’ve ever seen it yet – reports suggest that the higher-tune ’S’ version could have up to 600 hp. The regular E 63 will offer close to 550 hp.

Rumour has it that rear-wheel drive versions of the E 63 will be discontinued. The model will pick up a 4Matic all-wheel drive system instead, possibly so to cope with the immense power output. Another possible surprise for the E 63 is that for the first time ever, Affalterbach could sign off on a coupe body style too – joining the expected sedan and estate versions.
