The 2018 Mercedes-AMG GLC63 and GLC63 Coupe are your insane compact SUVs

The 2018 Mercedes-AMG GLC63 Coupe and SUV will be the eighth application of the AMG badge onto an SUV frame (joining GLA45, GLC43, GLE43, GLE63, GLS63, G63, and G65). The GLC63 will be offered in the SUV body shape, while the SUV “coupe” gets GLC63 and GLC63 S variants. All come witha  bi-turbo V-8 and up to 503 horsepower. The GLC63 and GLC63 S are separated by 34 horsepower, producing 469 hp and 503 hp, respectively. The engines are rated at 479 and 516 pound-feet of torque, respectively.

Regardless of body style or engine configuration, the GLC63 will get standard all-wheel drive, which Mercedes calls “4Matic,” and a 9-speed automatic that’s used widely across the AMG range. According to the automaker, the GLC63 will hit 60 mph in 3.9 seconds, while the GLC63 S does the deed in 3.7 seconds.

When they go on sale early next year, the GLC63 will feature performance upgrades that will help manage its prolific speed.

First, the GLC63 gets AMG’s multi-chamber adaptive air suspension as standard; it toggles among Comfort, Sport, Sport+, and Race settings. The front axles keep the same four-link setup with AMG-specific knuckles and tuning to tame torque-steer from the high-po V-8. The rear axles on the GLC63 come from the E63 S sedan and feature a wider track to handle the 20-inch, 255-millimeter wide tires in back (295-millimeters wide for GLC63 S models). A standard limited-slip differential handles power along the back axle; the GLC63 gets a mechanical differential, while the GLC63 S upgrades to an electronic limited-slip differential.

Visually, the GLC63 separates itself from the rest of the AMG SUV range with the automaker’s Panamericana grille, which is lifted from the AMG GT. A wider rear bumper is stretched around the quad-tipped tailpipes and rear diffuser, and a hatch-mounted lip spoiler makes all the downforce.

Inside, the usual AMG upgrades include leatherette and microfiber buckets up front, with a leatherette instrument panel and upper dash, and aluminum trim with carbon fiber accents. The application of carbon fiber in a 2-ton SUV is just our kind of channeled dementia.

Upgrades for the GLC63 include deeper AMG buckets with nappa leather, a Night appearance package, 21-inch wheels, and a selectable active exhaust that will likely terrify neighbors. (All models come with an automatically adjusting exhaust flap, but you have to pay more to do it yourself.)

The GLC63 will compete against the Porsche Macan Turbo for now, but we expect that other contenders will emerge fast and thick. Already we know BMW is prepping a X3 M, Jaguar is working on an F-Pace SVR, and Audi is considering an RS Q5.

Mercedes-AMG hasn’t yet announced pricing for the GLC63, but we should know more before it arrives next year.

The 2018 Mercedes-AMG GLC63 will appear in the flesh at the New York auto show next week, and a week later at the Shanghai auto show. To learn about the other vehicles appearing at the New York auto show, head to our dedicated hub.
