Mercedes has staged the North American debut of the GL63 AMG at the Los Angeles Auto Show.

Designed to be one of the fastest seven-seat crossovers on the planet, the GL63 AMG is distinguished by an aggressive front fascia, LED daytime running lights and 21-inch alloy wheels. There's also a unique rear bumper and a four-tailpipe exhaust system.

Power is provided by a twin-turbo 5.5-liter V8 engine that develops 550 bhp (410 kW) and 560 lb-ft (760 Nm) of torque. It is connected to a seven-speed AMG SPEEDSHIFT PLUS 7G-TRONIC transmission and a 4MATIC all-wheel drive system which enables the model to accelerate from 0-62 mph in 4.9 seconds, before hitting a top speed of 174 mph (280 km/h).

The 2013 GL63 AMG will go on sale in the United States early next year and pricing starts at $116,925.
