Fresh off the G-series first complete redesign in nearly 40 years, Mercedes has unveiled the AMG G63. Simply put, the G63 is more of everything that makes the G-series great. A twin-turbo V8 makes 577 horsepower, mated to a nine-speed transmission and rear-biased all-wheel drive. Wider fenders, side-exit exhaust, and a new grill make certain it won't be mistaken for the lesser G550. Expect more details when Mercedes officially debuts the G63 at the Geneva International Motor Show in March 2018.
