Mercedes-Benz MLC AMG

First BMW, now Mercedes-Benz. The German luxury manufacturer appears hard at work on its very own challenger to BMW's four-door coupe/crossover, the X6. It's called the MLC, and we've shown it to you before. Just a few weeks back, in fact.

Unlike the last set of spy photos we showed you, though, this particular tester gives us our first glimpse at the MLC's brawnier AMG variant. Our spies report that under hood will be the same 5.5-liter, biturbocharged V8 found in the ML63 AMG, and that it will sing its boisterous song with the tune of 557 horsepower. That means Mercedes is set to challenge the BMW X6M for the title of most unlikely ridiculously fast vehicle on the planet.

Beside the extra boost in power, we can spot a number AMG styling cues here. Most noticeable are the more substantial wheels and tires, bigger brakes and the larger front intakes. AMG-style exhaust tips jut out the back, which are accented with larger vents in the rear bumper and swollen fenders at all four corners.

According to our spies, we should expect to see the regular-strength MLC at the 2015 Geneva Motor Show, while the AMG model will arrive a few months after that. So basically, we should have all the details on the MLC AMG in about a year.
