Wiesmann has revealed technical details of Project Thunderball, the world's first electric convertible roadster.
The two-seater, rear-wheel drive car sees twin electric rear-mid mounted motors delivering up to 500kW (680hp) to the rear wheels and 1100 Nm of torque, resulting in a targeted 0-62mph (0-100km/h) sprint acceleration time of 2.9 seconds.
Thunderball is built on a bespoke chassis architecture with its powertrain components packaged to provide the lowest possible centre of gravity, the company said.
The vehicle weighs 1,700 kg (3,747lbs) and provides 2.5kg per HP of performance. It comes equipped with a 92 KWh bespoke battery pack for 500 km (310 miles) range.
The vehicle's state-of-the-art 800V high-voltage architecture enables ultra-rapid 300 kW DC fast charging at a public charger or charging domestically via its 22-kW onboard charger. Charging is provided via a standard CCS charging port.
To implement the idea of how an emotional EV drives, a unique Intelligent Regenerative Braking System has been specifically developed.
With five setting levels available, the steering wheel-mounted paddles allow instant adjustment of the car’s regenerative braking power, much like the shifting of gears on an ICE car, so drivers are more involved.
Moreover, the driver can change the twin electric motors’ feel to give a powerful engine braking effect when going downhill or braking into corners, which recharges the battery to regain additional range, and allowing optimum use and minimal waste of energy, the company said.
“The continued development of Project Thunderball is bringing Wiesmann ever closer to the goal of producing what will be the world’s most exciting electric sports car,” said the CEO of Wiesmann, Roheen Berry.
Since opening the reservations list at the end of September, the company has three-fourth of the first year of production slots allocated, it said.
