When Mercedes-AMG created the GT family it was quite open about the fact that it was aiming for the likes of Porsche’s 911 range. To do so, Mercedes needed to offer many options to give potential buyers the exact car they wanted.

Plenty of options

To date, the company has launched an entry level GT, a hotter GT S and the apex model, which is called the GT R. Each uses the company’s twin-turbocharged V8 motor in various states of tune. That’s the hard-top, two-door branch of the family tree.

Then there are three versions of the four-door model called: GT53, GT63 and GT63 S; the latter two use the same engine, with different power outputs. The 53 model uses a turbocharged inline six. Still with me?

Topless motoring

If you’re a sun-seeker then there are options for you, too. There are currently topless GT and GT C variants. And now Mercedes expands the drop-top range by adding a new model to the mix. A GT S Roadster takes up station in the range between the existing drop-top cars.

In the GT S the ubiquitous twin-turbocharged 4,0-litre V8 makes 384 kW, which is 34 more than the GT, and 26 less than the GT C. Peak torque is rated at 670 N.m only ten shy of the GT C.

As with all the two-door GTmodels power is sent to the rear axle via a seven-speed dual-clutch transmission. Mercedes claims a 0-100 km/h time of 3,8 seconds, just one-tenth shy of the GT C, but 2/10ths quicker than the GT roadster. Flat out it’ll do 308 km/h.

The GT and S look quite similar except for the wheels. The GT C uses a wider body that the other open-top models, hence a slightly more aggressive stance.

Upgraded

The S badge brings more than just a few kilowatts extra, there are quite a few differences between the GT and S.

Under the skin it gets adaptive suspension, an electronically-controlled limited slip differential, variable-sound exhaust, 10-mm wider front tires, one-inch taller rear wheels, and an extra driving mode called ‘race’.

Not too different inside

The interior treatment of the GT S roadster is similar to that of its siblings. That is to say, it has a wide centre console with a driver-centric layout. If you prefer to enjoy your roadster in winter you’ll be happy to note that the seats feature the company’s warm-air system referred to air scarf.
