This might just be the most raucous drop-top you can buy – the new Mercedes-AMG GT R Roadster. AMG’s 4.0-litre, twin turbo V8 engine always sounds absolutely filthy, particularly in the AMG GT R coupe. Take the roof off and it will probably sound like being sat in the middle of a medium-sized tornado.
In the AMG GT R Roadster, that engine produces a fullsome 585hp and 516lb/ft of torque, sent to the rear wheels via a seven-speed dual-clutch gearbox.
It’s not exactly a light car, but even so the open top AMG GT R dispatches the 0-62mph sprint in just 3.6secs – as quick as the hardtop – and tops at a limited 197mph. If you’re lucky, you’ll see a combined 22.6mpg.
The roof opens and closes in 11secs at speeds up to 31mph. The triple-layer top has a lightweight structure and an acoustic mat to reduce noise. But why you would ever want to drive it with the roof up is beyond us. It’s got seat heaters, furnace-like blowers and the ingenious Aircalf, so you’ll be snug and warm even in the depths of winter.
Gadgets include a 12.3in digital instrument panel, 10.25in infotainment screen, LED headlights with adaptive high beam, Burmester stereo and a full suite of driver assistance aids. Ceramic brakes are an option.
As you’d expect, all this doesn’t come cheap. The AMG GTR R Roadster will set you back £178,675 – a whopping thirty grand more than the coupe.
Is it worth the extra just to have unfettered access to that thunderous exhaust note? We think so.
Orders are being taken now for deliveries towards the end of this year.
