The carbon fibre-bodied roadster will command a premium over the £215,000 coupe.

VLF Automotive is set to reveal the roadster version of its Force 1 sports car more than a year after the coupe made its official debut at the Detroit Auto Show. Ahead of its official debut at next week's Auto Shanghai in China, we've bagged these revealing images of the show car spotted in transit.

It looks just as aggressive as the coupe, but with a soft top instead of the fixed carbon roof. Speaking of which, all of the body panels are made from carbon fibre to keep the weight down low. While the coupe tips the scales at 1,538kg, its droptop counterpart might be a tad heavier because of the increased roof complexity.

Assuming the roadster has the same engine specification as the coupe, it means there’s a Dodge Viper-sourced V10 8.4-litre naturally-aspirated engine upgraded to push out a meaty 745hp and 638lb ft of torque. In charge of sending all that power to the rear axle will likely be a six-speed manual or a six-speed automatic gearbox.

As far as performance is concerned, it should be very similar to that of the coupe. The hardtop model needs approximately three seconds to hit 62mph and maxes out at 218mph.

There’s no word on price just yet, but taking into account the coupe costs $268,500 (around £215,000), it wouldn’t be too far-fetched to assume the roadster will be more expensive.

Besides the Force 1 duo, VLF Automotive is also making the Destino. It’s a thoroughly upgraded Fisker Karma with a Corvette ZR1-sourced 6.2-litre V8 and a hefty $229,000 (£185,000) price tag. All three cars are being put together at a factory in Auburn Hills, Michigan.

The Auto Shanghai show begins on April 19th - and Motor1 will be reporting on all the big reveals, including the full details on the new VLF Force 1 Roadster.
