Teased last month, the VLF Force 1 Roadster – the drop supercar being codeveloped by acclaimed car designer Henrik Fisker, former GM head honcho Bob Lutz and racing driver Ben Keating – has been spied as it makes its way to Shanghai in time for next week's auto show. As predicted, the Viper-powered roadster will come with a retractable cloth roof. The design mimics that of the coupe, right down to the stunning twin four-spoke alloys.

Powertrain details have yet to be disclosed, but it's fair to assume it will have the same 8.4-liter V10 as its coupe counterpart with around 745 horsepower on tap. The extra weight of the convertible will translate into a slightly slower 0-60 mph time , but we're still expecting the century sprint to happen in around 3 seconds, while top speed should be around the 210 mph mark. Power in the VLF Force 1 coupe is sent to the rear wheels through either a six-speed manual gearbox, or an optional six-speed automatic paddle shifter setup, and we expect the same options to be available in the convertible.

Standard equipment also includes 21-inch wheels wrapped in Pirelli P Zero tires, Brembo performance brakes and a lightweight carbon fiber body construction. The VLF Force 1 Roadster will be unveiled at the Auto Shanghai on April 19, and we'll be standing by at the show to share live photos of the reveal with you.
