Mercedes AMG GT R Roadster

The Mercedes-AMG GT range has grown again, this time with the arrival of an open-topped GT R Roadster. Affalterbach says the new car will be limited to just 750 units, and is aimed at ‘a new, lifestyle-oriented target group which lives life to the full.’

The Roadster GT R keeps the same 4.0-litre V8 biturbo block as the standard car, while 0-62mph comes in just 3.6 seconds – just as fast as the Coupe. Top speed is down by 1mph though; the GT R Roadster maxes out at just 197mph.

We’ll update this article when Mercedes reveals pricing information for the new car.

AMG GT: what’s new for 2019?

Both Coupe and Roadster get exterior and interior tweaks, with a (slightly) less cluttered centre console as per the new AMG GT 4-door, a new digital instrument panel and a new wheel, with swipeable Touch Control pads as per the CLS, A-Class, AMG GT 4-door and others.

The range still starts with the entry-level AMG GT, followed by the AMG GT S, AMG GT C and AMG GT R, and now the new GT R Pro variant.

All cars still feature the impressively responsive hot-in-vee 4.0-litre V8, with power on a sliding scale according to model from 469bhp to 577bhp.

AMG GT R Pro: new GT racing-inspired range-topper

Headline act for the updated AMG GT range is the limited-edition Mercedes-AMG GT R Pro.

AMG claims lessons learned in its GT3 and GT4 racing exploits have been directly applied to its raciest grand tourer yet, with a built-in rollcage, racing-style coil-over springs and adjustable dampers and an evil looking aero kit, diveplane flicks and all.

A road-legal GT racer that can lap the Nurburgring in almost seven minutes flat (AMG factory driver Maro Engel recorded a 7min04sec lap in November in a disguised GT R Pro), it’s one of the least practical cars on display at LA but the most alluring if you have a one-track mind.

What else is new?

Redesigned LED headlights, with more distinctive daytime running lights that double up as indicators, set against a darker background. Likewise the tail-lights appear deeper-set against a newly darkened background.

Sentient stability control: a new AMG Dynamics control mode for the ESP system is claimed to be able to predict what the car will do before the driver does, and has a sliding scale (no pun intended) of assistance levels from Basic through Advanced and Pro to Master, best left for circuit use.

If you do fancy a track day, the new AMG Track Pace function within the multimedia system can record telemetry from a set of race circuits around the world so you can analyse a raft of data from each lap.

AMG GT, GT S, GT C and GT R: how to spot the difference

The entry AMG GT model has round twin exhaust outlets, and the AMG GT S and GT C have twin trapeze-shaped outlets. All three core AMG GT models have been given a new rear diffuser apron.

The hardcore AMG GT R has a cavernous central exhaust outlet, with two further round exhaust exits either side.
