What hadn't been divulged until today was the SLS AMG Roadster's powertrain and performance figures. Motivation is provided by AMG's trusty 6.2 litre V8, producing 420kW and 650Nm of torque - figures shared with its hardtop sibling.
With power transferred to the wheels through a seven-speed Speedshift dual-clutch transmission, the Roadster hits 96km/h (60mph) from standstill in 3.7 seconds. Another figure the Roadster has in common with the Coupe.
As with most supercoupes-cum-convertibles, the SLS AMG Roadster gets a number of chassis-strengthening modifications. Despite these enhancements, the Roadster is a mere 40kg heavier than the Coupe.
On the styling front, the Roadster and Coupe are largely identical front and rear. But, unlike the iconic gullwing design of the SLS AMG hardtop, the Roadster gets conventional doors and an electric folding fabric roof.
Available in black, red or beige fabrics, the roof can be packed away or locked in place in just 11 seconds, at speeds up to 50km/h.
Inside, the Roadster offers the same classic 300SL inspired features, including an upright dash and gimball-mount air vents.
Speaking with TMR today, Mercedes-Benz Australia's David McCarthy confirmed that the SLS AMG Roadster will make its local debut in the first quarter of 2012.
He added that four buyer orders have been placed already, with pricing to be confirmed closer to launch.
