It's big. It's green. So our spy photographer has decided to call what is essentially a four-wheel variant of the Mercedes G63 AMG 6x6 the "Green Monster," and/or "the Hulk." Caught testing in southern Europe, we prefer to call it the G63 AMG 4x4 – because that's what the German marque will probably call it. As you can see, it wears the same body modifications as the 6x6, with wider fender flares, restyled side skirts and a new rear bumper.

It also boasts a significantly increased ride height, roof-mounted auxiliary lights and massive offroad wheels covering five-spoke alloys. Power will come from AMG's 5.5 liter twin-turbo V8 developing 544 horsepower 560 lb-ft of torque, which will be sent to all four wheels via the seven-speed G-tronic automatic transmission. The Mercedes Green Monster (there, we said it) is expected to debut sometime in 2015.
