Sport Auto's road test editor Christian Gebhardt has sent us his latest test video, this time for the Mercedes-Benz SLS Roadster.

As a refresher, the SLS AMG Roadster debuted at the Frankfurt motor show in 2011. Without gullwing doors it is the roadster variant of the SLS AMG which features the same power plant - a 6.3-liter (6,208cc) V8 engine that produces 563 hp (420 kW / 571 PS) and 479 lb-ft (650 Nm) of torque. Transmission is a seven-speed dual-clutch gearbox.

In the video we can see Gebhardt taking the SLS Roadster on a top speed flight which hits 327 km/h (203 mph) on speedometer and 325 km/h (202 mph) according to GPS readings.

In Sport Auto's performance test at Germany's Hockenheimring the SLS AMG Roadster impressed with a lap time of 1:11.6 minutes as compared to other drop top types (except SL65 Black Series):

  • Porsche 911 Turbo S Cabriolet 1:11.9 min
  • Mercedes SL 65 AMG Black Series 1:12.2 min
  • Audi R8 Spyder 5.2 FSI quattro 1:12.7 min
  • Mercedes SLR McLaren 1:13.5 min
  • Ferrari California 1:13.5 min
  • Aston Martin DBS Volante 1:14.8 min

Out of the range of vehicles the magazine has had the opportunity to test, the only production roadster to beat the SLS so far is the Lamborghini Gallardo LP 560-4 Spyder with a time of 1:11.1 minutes.

All impressive numbers but perhaps the most surprising number which shows how badly performance is compromised in the roadster variant is when you look at the time for the regular SLS AMG Gullwing which posted 1:10.8 min - almost a full second slower.
