The updated Mercedes-AMG GT and a new GT R Pro variant have been unveiled at the 2018 Los Angeles motor show.
The new Mercedes-AMG GT R Pro is a limited edition model said to incorporate learnings from AMG's GT3 and GT4 race cars, adapted for life on the road.
As such, the driver is able to mechanically set (without tools) the suspension's spring pre-load length, and adjust the compression and rebound rate of the dampers.

Other changes include an adjustable front axle torsion bar, spherical bearings for the rear upper wishbones, and retuned dynamic mounts for the engine and transmission.
There's also a carbon-fibre shear panel to stiffen the rear end, ceramic composite brakes, lightweight forged alloy wheels, a new lip for the rear spoiler, vents above the front wheel arches, and a front fascia with an extended front splitter held up by metal braces and new flics.
To make the Pro stand out even further, it is fitted as standard with plenty of visible carbon-fibre elements and a racing stripe package.
Above and below: Revisions to the rest of the GT two-door range.
Buyers of 'lesser' AMG GT models will benefit from a host of small updates, including a now-standard 12.3-inch instrumentation screen, a grippier steering wheel design first seen in the GT four-door, revised LED headlight graphics, revised wheel designs, and a new rear bumper and diffuser.
There's also AMG Track Pace, a track-only data logging mechanism, and the AMG Dynamics stability control system with a variety of new driver selectable modes.
Power from the 4.0-litre twin-turbo V8 is unchanged. The base GT is credited with 350kW/630Nm, the GTC boasts 410kW/680Nm, and the GT R and GT R Pro both have 430kW/700Nm.
Mercedes-Benz Australia has confirmed the refreshed GT is bound for our shores in the second half of 2019. The new Pro model hasn't been confirmed, with the brand telling CarAdvice it's "under consideration" for Australia.
