Mercedes-AMG is now offering the running gear of the GT S with the Roadster body, plugging a gap in its sports car line-up for a middle-ground drop-top.
Powered by a 515bhp and 494lb ft-producing turbocharged V8, the new convertible GT S sits between the entry-level 469bhp GT Roadster and the 549bhp GT C Roadster.
As such, the performance enabled by the GT S-spec 4.0-litre engine places the car directly between its two siblings, with a 0-62mph sprint time of 3.8sec and a top speed of 191mph.
Like the rest of the GT range, the GT S drives its rear wheels through a seven-speed dual-clutch automatic gearbox. However, it also gets a standard sports exhaust and an electronically controlled limited-slip differential that isn't offered on the lesser GT. Also included are adaptive dampers, along with 19in front and 20in rear alloy wheels.
The GT S has the same driveline as the GT, rather than the wider tracks of the GT C and GT R (which isn't available as a Roadster). However, the four-wheel steering system of the GT C and GT R is an option on the GT S.
In addition, buyers can specify the AMG Dynamic Plus package, which brings firmer suspension, active engine mount and quicker-responding steering. Inside, the pack adds Nappa leather and Dinamica upholstery.
Mercedes-AMG is taking pre-orders for the GT S Roadster now, although it won’t be launched in the UK until July. Prices start from £126,730 - directly in the middle of the GT roadster and more hardcore GT C roadster, and £11,400 more than the GT S coupé. Ceramic brakes are a £5995 option, while the £1695 Driving Assistance package adds blind spot monitoring, lane keep assist and other safety systems.
