Mercedes-Benz’s updated E63 AMG has made its debut at the 2013 Detroit Auto Show and these are the first live images of the new brute.

Looking every bit as menacing as its numbers would suggest, the new E63 AMG is now officially the fastest four-door in production.

This is made possible due to two key reasons: the car is now available with 4Matic all-wheel drive, an option that is standard in the U.S., and it’s also available in a new range-topping S-Model trim that sees its output lifted to 577 horsepower and 590 pound-feet of torque.

Combined with the added traction of all-wheel drive and a supercar-like power rating, the Mercedes-Benz E63 AMG 4Matic S-Model will rocket to 60 mph from rest in just 3.5 seconds. It can also reach an electronically limited top speed of 186 mph.

The regular model is no slouch either, with its increased output of 550 horsepower and 531 pound-feet of torque, able to accelerate it to 60 mph in less than 4.0 seconds as well.

These live photos show the sedan though an E63 AMG wagon is still available.

Sales of the latest AMG sledgehammer, which will list as a 2014 model, commence this summer. The BMW M5 and even the recently revealed Audi RS 7 look like they're not quite up to matching the E63 AMG in the performance stakes. We'll have to reserve judgement until we're driven all three.
