Arcspeed electric roadster will have a rear-mounted electric motor that makes 385 lb-ft (521 Nm) of torque.

Australian automaker Arcspeed is building an electric roadster that is set to rival the Tesla Roadster.

The Arcspeed roadster features the same electric motor used in the Varley evR450 which reportedly makes 385 lb-ft (521 Nm) of torque. Arcspeed says the new roadster will do the 0 to 60 mph (96 km/h) sprint in less than 3.8 seconds.

The roadster will have a very low center of gravity, as one can tell just by looking at how low-cut the car is. The electric motor will be rear-mounted and the car will, of course, be a rear-wheel drive. The lithium-ion phosphate battery pack will be fitted beneath the cockpit floor.

The roadster was initially designed to be a petrol-powered car when difficulties led Arcspeed founders to change direction and go emmissions free. The electric roadster will be sold on the Australian market but could also be exported to other countries. Arcspeed says it is aiming for a selling price of less than $100,000 (U.S.), which would make it a little cheaper than the Tesla Roadster.

The car could possibly go on sale as early as the end of 2012.
