Lotus has shown the world's first fully electric hypercar, based around a 2,000 kW lithium-ion battery and management system from Williams Advanced Engineering (WAE).
Lotus has shown the world's first fully electric hypercar, based around a 2,000 kW lithium-ion battery pack and a battery management system from Williams Advanced Engineering (WAE).

Production of the Lotus Evija electric hypercar will be limited to 130 vehicles when it starts in 2020 and has a target power of 2,000 PS and 1,700Nm of torque. This is the first completely new car to be launched under the stewardship of Geely, which also owns the Volvo group.

The battery pack is mid-mounted immediately behind the two seats and supplies energy directly to four motors. With a target weight of just 1,680 kg, it will be the lightest pure electric hypercar to go into series production. Power is fed from the battery pack to a bespoke in-line axial arrangement of two high-power density e-motors. These feature integrated silicon carbide (SiC) inverters and epicyclic transmission on each axle of the four-wheel drive powertrain. The motors and inverters being supplied by the e-Drives division of Integral Powertrain.

The electric hypercar will have a range of 250 miles (400km) and a top speed of 200 mph (320 km/h).

“Integral Powertrain is committed to extending the boundaries of e-drivetechnology and enabling our clients worldwide to produce amazing products. This is exemplified in this project with Lotus Cars for which we will be engineering and supplying one of the most power dense integrated motor inverter packages available. It is a privilege to work with Lotus and we are looking forward to seeing the Evija on the road,” said Luke Barker, director of Integral Powertrain .
