Wiesmann, the German luxury sports car marque, has revealed technical details of its all-electric vehicle codenamed Project Thunderball – which it claims is the world’s first electric convertible roadster.
The two-seater, rear-wheel drive Project Thunderball sees twin electric rear-mid mounted motors delivering up to 500kW (680hp) to the rear wheels and 1100 Nm of torque, bringing phenomenal straight-line performance and a targeted 0-62mph (0-100km/h) sprint acceleration time of 2.9 seconds.
Project Thunderball has been built on a bespoke chassis architecture with its powertrain components cleverly packaged to provide the lowest possible centre of gravity. To keep the typical roadster proportions, the position of the driver and passenger are positioned as far backward as possible, presenting a challenge to integrate the drivetrain and large battery into the vehicle’s small footprint.
The vehicle’s powertrain combined with its carbon fibre body weighs in at little more than 1700kg (3747lb), providing an outstanding 2.5kg per HP of performance.
