Caterham unveils electric Seven prototype

Weighs less than 700 kilograms

The Caterham Seven is a lightweight car, but wouldn't an electric version be very heavy? Not at all. Caterham has now unveiled an electric prototype of the Seven which is expected to weigh under 700 kilograms. The manufacturer has used the same chassis as the fossil fuel version and Swindon Powertrain has developed an electric motor that has been placed at the rear. It delivers 178 kW/243 horsepower and has a torque of 250 Newton meters. The car is expected to go from 0-100 km/h in around four seconds. The battery pack has a capacity of 51 kWh, of which 40 kWh is usable, and it is located under the front hood for optimal weight distribution. Cooling is achieved using a liquid that is in direct contact with the cells which is expected to provide better control of heat development. This should make the battery perform better during, for example, track driving. According to Caterham the car can handle 20-15-20 cycles, which means 20 minutes of driving, 15 minutes of charging and then another 20 minutes of driving. The car has regenerative braking and the battery can be fast-charged up to 152 kW.

The premiere will take place at the Goodwood Festival of Speed in mid-July. In addition to this Caterham is working on another fully electric sports car which they will reveal more about in the coming months.
