2020 Mercedes-Benz GLC300 and GLC63 first drive: Above and beyond

The GLC63 engine is the same as last year, a 4.0-liter twin-turbo V8 making 469 hp and 479 lb-ft. The GLC63 S goes a bit higher to 503 hp and 516 lb-ft. That S version is, by the way, now the fastest SUV at the Nurburgring with a time of 7 minutes, 49.369 seconds. It can also blast to 60 mph in 3.8 seconds, honestly supercar numbers not long ago. The base engine in the GLC300 is a new version of the 2.0-liter turbo four making 255 hp and 273 lb-ft. That’s a gain of 14 hp over the 2019. Euro versions do get the new 48-volt EQ Boost setup, but we won’t see that here, yet.
The AMG has a nine-speed multiclutch transmission while the base model gets a conventional nine-speed automatic. The AMG comes standard with 4Matic Plus all-wheel drive; on the GLC300 it’s a $2,000 option.
All GLCs get adaptive suspension damping with comfort, sport and sport plus modes. AMG versions come standard with the Mercedes’ new three-chamber air suspension.
That new off-road mode comes with off-road-mode specific information in the new MBUX (Mercedes-Benz User eXperience) infotainment system. The 10.25-inch, high-definition central screen has a bunch of different view modes and features including augmented reality navigation, a multitude of camera angles and the rest of the usual stuff (radio/phone/media) just like its bigger GLE brother.
