Mercedes-AMG is currently hard at work developing and testing its latest model, the E63 AMG. Set to be offered in two body styles and potentially, three variations, the German company’s latest and craziest model was recently filmed up close.

This particular spy video opens on a prototype of the latest-generation E63 AMG sedan. It can be clearly differentiated from the standard model thanks to a modified trunk lid, a new rear bumper with AMG’s characteristic quad exhaust pipes, a set of flared side skirts, widened wheel arches and an extensively modified front fascia.

Beneath the new front end will be the company’s 4.0-liter twin-turbocharged V8 engine. In standard guise, this powertrain should deliver 571 hp and 553 lb-ft of torque while the E63 S version may bump those figures up to 612 hp and 626 lb-ft. Offered exclusively in conjunction with an al-wheel drive system, the new E63 AMG will be the most potent car of its kind.

Also being tested in the Estate version of the car. Looking very similar to the latest C63 AMG Estate, it could prove the most visually appealing of the pair.

As if the standard model won’t be insane enough, there’s talk that a Black Series badged version is also being developed. If this is the case, such a model could quite easily deliver up to 650 hp.
