The 2010 Mercedes-Benz G55 AMG is a performance-tuned variant that stands out in the class of luxury large SUVs for its bold, military-inspired exterior design and superb off-road capabilities. Some critics have taken issue with its mediocre on-road handling, poor gas mileage and expensive price tag. Powering the G55 AMG is a 500 horsepower AMG-built V8 engine that's quite powerful but still doesn't deliver much in the way of on-road refinement.
A noted critic of the G55 AMG is that the vehicle is too stiff, heavy, and boxy to handle. While that may be the case, it's important to recognize that this luxurious SUV is geared more towards drivers seeking exclusivity than sports performance. That doesn't mean that the G55 AMG is now fast. The engine under the hood helps this SUV propel itself from 0 to 60 mph in just 5.5 seconds. There aren't too many SUVs out there on the road that can boast about those numbers.
