Mercedes-Benz GL 63 Biturbo by Brabus

It seems like the AMG catalog grows exponentially with every passing year. The Mercedes performance division offers versions of just about every Benz in the range, save one: the GL-Class crossover. Oh, they offer performance versions of the ML, the G, even the ML, but not the GL. For that, you'll need to look to the aftermarket. And Brabus is glad to help.

The venerable Mercedes tuner shares a close relationship with the manufacturer, and has transplanted the AMG-sourced 6.3-liter V8 engine into the GL, with a couple of turbochargers thrown into the mix. With 650 horsepower and 620 lb-ft of torque, the Brabus GL 63 Biturbo hits 100 km/h (62 mph) in 4.7 seconds and tops out at an Autobahn-crunching 300 km/h (1867 mph). Nice work.

There's also a fully customized interior with special leather, carbon fiber trim and LCD screens, and a Widestar body kit to give the truck a suitably aggressive upgrade. The cost? An eye-watering €368,000 ($518k). See for yourself in the gallery below in advance of the truck's official launch at the upcoming Geneva Motor Show in March.
