UM. 2016 Mercedes-Benz G65 AMG. “As much as we love to drive at high speed, that 143-mph limiter is probably a good idea. At that speed, the chassis will put the fear of God into you. The imprecise steering, perfect for negotiating rocks and off-road obstacles, begins to feel positively vague; body roll becomes excessive; and the driver needs to stay laser-focused to keep the G65 AMG in its lane. He won’t have to stay focused for long: The real-world appetite of 7-to-9 mpg quickly drains the 25-gallon tank. Off road, the AMG versions of the G lose some capability, not least because of their 275/50 high-performance tires on 20-inch wheels.”
