While it may seem ill-advised to anybody who has ever pushed a G-wagen’s dynamic envelope, the 850 6.0 Biturbo Widestar will imbue the block-shaped SUV with an eponymous 850 horsepower and a mountainous, 1069 lb-ft of torque. That’s enough to send it to 62 mph in a claimed 4.0 seconds—which is about as quick as the new Mercedes-AMG C63 sedan.
