More photos of the Mercedes-Benz SLS AMG Roadster have come about, as well as further details on features and kit. The vehicle, which rolls in at 1,660 kg (40 kg more than the Coupé), is of course due to make its official debut in Frankfurt in September before beginning to enter European markets before the year is out.

The car wears the same 6.3 litre V8 engine as the Coupe, and with the AMG Speedshift DCT 7-speed sports transmission in attendance, offers comparable performance – the 571 hp and 650 Nm on call offers a 0-100 kph sprint time of 3.8 seconds and an electronically-limited 315 kph top speed.

The fabric soft top, which can be opened and closed in 11 seconds while on the move at up to 50 kph, will come in three colour choices – black, red and beige, to suit the nine exterior and eight interior colours available for the vehicle. Boot capacity is 173 litres, just three litres less than the Coupe version, and this is the same with the roof open or closed.

As for interior trim, owners will be able to pick from the finest leather, matt-finished solid metal or optional, real carbon-fibre trim. Standard issue on the SLS AMG Roadster include black designo leather, AMG sports seats with heating, a slot-in glass draught-stop, Comand APS with DVD player, anti-theft alarm system with tow-away protection and interior monitoring, Thermotronic luxury automatic climate control and Keyless-Go start.

Single-tone or two-tone designo leather in espresso brown is available as a new interior colour – this dark shade of brown matches an optional new metallic paint finish called AMG Sepang brown. Leather-lined roll-over bars with integrated mesh in a “Silver Shadow” look are available with the optional designo Exclusive leather, and ambient lighting is integrated into the optionally available, electrically folding exterior mirrors.

Other available options include the Airscarf system, integrated into the backrests of the AMG sports seats, and a Bang & Olufsen BeoSound AMG surround sound system, as well as an Android-based AMG Performance Media system, replete with vehicle telemetric data displays and high-speed mobile internet access.

In addition to the standard-fit AMG seven-spoke light-alloy wheels, 5-twin-spoke wheels and weight-optimised 10-spoke forged wheels – painted in matt black with a high-sheen rim flange – are on the options list, and the SLS AMG Roadster wears 265/35 19-inch front and 295/30 rear 20-inch rear tyres, with a tyre pressure monitoring system fitted as standard.
