As the name would suggest, the G65 ditches the 536-hp, twin-turbo 5.5-liter V-8 found in the G63 AMG, and shoehorns in a twin-turbocharged V-12 churning out 621 hp and a monumental 738 lb-ft of torque. This is enough to hustle the 5,700 lb beast from 0-60 in 5.3 seconds, on to an electronically limited top speed of 143 mph.
The sturdy G-Wagen structure ensures that the 2016 Mercedes-AMG G65 is just as capable off-road as it is on-road. As is standard on the rest of the G-Class lineup, the G65 features three individual locking differentials, making it capable of navigating some seriously rough terrain.
The 2016 Mercedes-AMG G65 makes its official debut at the 2015 New York auto show. In the meantime, check out the most powerful production SUV on the market in the photos below.
