New Mercedes-AMG GLC 63 SUV and Coupe break cover

MERCEDES-Benz has detailed its new hardcore AMG SUVs.

The German brand's ever expanding performance arm has released its latest ferocious combination - the Mercedes-AMG GLC 63 S SUV and Coupe - at the 2019 New York motor show.

The SUVs are built on the same platform but one uses a more conventional SUV body and the other the out-there swoopy styling.

Mercedes-AMG claims the GLC 63 S is the fastest SUV around the Nurburgring.

Australia will get only the more potent all-wheel drive S versions, powered by a twin-turbocharged 4.0-litre V8 (375kW/700Nm) paired to a nine-speed automatic transmission.

AMG claims the pair can sprint from 0-100km/h in a blink-and-you'll-miss-it 3.8 seconds on the way to a top speed of 280km/h. Mercedes-Benz maintains that the AMG 63 S is still the fastest SUV around the benchmark Nurburgring racetrack.

All are impressive numbers for a machine that weighs well over two tonnes. Mercedes-AMG also says the pair drink (an irrelevant claim) 12.3L/100km.

2019 Mercedes-AMG GLC 63 S Coupe comes with a new Slippery driving mode.

There are six driving modes including a new Slippery setting that is used in low traction onditions and reduces power to the wheels. Cornering stability and traction are assisted by the electronically locking differential which reduces slip on the inside rear wheel when cornering.

Mercedes-Benz has loaded the performance pair with its latest technology including the M-BUX (Mercedes-Benz User eXperience) digital assistant.

This controls the car's navigation, climate and infotainment settings and responds to simple "Hey Mercedes" voice prompts.

The GLC’s interior has been reworked rather than receiving a full revamp.

The GLCs keep the brand's conventional digital display layout with a separate digital instrument and central infotainment screen, as opposed to the continuous dual-screen layout available in the new A-Class.

Mercedes has also given the AMG pair a few styling tweaks, adding new head and tail-light designs, fresh 21-inch alloy wheels and larger twin tailpipes.

The two range-topping GLC versions will arrive in Australia in October with prices expected to start about $170,000 before on-road costs.
