the Mercedes-Benz G550 has a V8 engine that helps deliver quick acceleration, according to reviewers. They say the G63 AMG, with its twin-turbocharged V8, is even faster, with incredible power that belies its size and weight. The seven-speed automatic transmission in both models is praised for its quick, smooth shifts, though critics find it occasionally hesitant to downshift when more power is needed. At an EPA-estimated 13/14 mpg city/highway. Auto journalists write that the G-Class has a firm ride over highway imperfections and exhibits quite a bit of body lean in turns, and as a result, generally feels clumsy on paved roads. Others mention that it requires fairly long distances to bring it to a complete stop. Still, reviewers say the G-Class has impressive off-road capability, and can tackle nearly any trail it is put on.
Reviewers say the G-Class has superb cabin build quality and first-rate materials. Critics mention that the G-Class’ front seats are comfortable, but have somewhat limited legroom. Others mention that legroom in the rear seats could be better as well. The G-Class offers less cargo space than many rivals, and reviewers say that the rear wheel wells can get in the way when loading wide cargo. Test drivers agree that the standard COMAND infotainment system takes a while to master but is generally easy to use once learned. Most features on the G-Class come as standard equipment, including a Harman Kardon stereo system, navigation, a rearview camera, blind spot monitoring, Bluetooth, leather seats, heated front and rear seats, ventilated front seats and dual-zone automatic climate control. Upgraded leather and a heated steering wheel are optional.
Mercedes rarely updates the G-Glass but the 2021 model is more significantly updated than you might think upon a quick glance at its familiar exterior design. For 2021, the G-Glass gets updated with a new interior, new independent front suspension, more interior room, and a new nine-speed automatic transmission.
