Updated Mercedes-AMG GLC 63 S revealed as fastest SUV to lap the Nurburgring

Mercedes-AMG has unveiled its facelifted GLC 63 and GLC 63 Coupé at the 2019 New York motor show and proclaimed the former to be the fastest SUV to have ever lapped the 12.9-mile Nürburgring Nordscheife.

The performance SUVs have received a series of subtle changes, most of which are focused on the exterior styling and upgrades to its interior.

New features include redesigned LED headlights and tail-lights and new trapezoidal twin tailpipes. Customers can now also specify new 21in alloy wheels and Graphite Grey Magno matt paint.  

The most significant upgrades are found inside, however. Included is a revised instrument binnacle and Mercedes’ new MBUX operating system with touchscreen, touchpad, voice and (optional) gesture control. There’s also a new AMG steering wheel that features touchpads within its horizontal spokes and offers additional upholstery options.

Power for the SUVs continues to be provided by AMG’s twin-turbocharged 4.0-litre petrol V8. Its output remains unchanged, so the standard cars make 469bhp and 442lb ft and the S versions 503bhp and 516lb ft.

As standard, drive is channelled through AMG’s nine-speed Speedshift MCT dual-clutch automatic gearbox and fully variable 4Matic+ four-wheel drive system. As an upgrade, all models now come as standard with an additional ‘slippery’ driving mode for damp or wet conditions as well as an electronically controlled locking differential.

AMG quotes a 0-62mph time of 3.8sec for both the GLC 63 S 4Matic+ and GLC 63 S Coupé 4Matic+. Their top speed is nominally limited to 155mph, but it can be increased to 174mph with the optional Driver’s Package.

The two also feature AMG-tuned suspension with adaptive dampers and so-called Ride Control+ air springs at the rear.

AMG claims the facelifted GLC 63 S 4Matic+ has become the fastest SUV to have lapped the Nürburgring, with a time of 7min 49.4sec.

“The lap record on the Nordschleife has proven the GLC 63 is right at the top of its segment in terms of dynamics,” said AMG chairman Tobias Moers. “With our V8, we hold a decisive unique selling point in the competitive environment. We were able to hone the dynamic even more and also further increase the suitability for every day.”
