The 2019 has three new wood trims: a glossy brown burl walnut, satin-finish ash gray, and something called Designo Magnolia Flowing Lines which is really striking. Most important to AMGers is the powerplant, led by a hand-built 4.0-liter twin-turbo V-8 engine that builds to 603 hp and 664 pound-feet of torque. It delivers the 4,800-pound bull-turned-cheetah to 60 mph in just 3.4 seconds. It's not a punishing sprint but a smooth, forceful run through the nine gears. The multi-clutch transmission will, however, lurch aggressively when the accelerator is mashed. And, it's not overly loud unless you want it to be _ there is a button to ramp up the exhaust volume. Credit Merc's 4Matic all-wheel-drive system for the superb handling, balance and traction on curves.
