Caterham introduces the EV Seven Concept
Caterham has built an electric sports car based on its legendary Seven model. It will never reach production, but all the technical specifications are available.
In terms of design, the all-electric ride is nearly identical to its gas-powered counterpart (see video). The British automaker says it is only around 70 kilos (154 pounds) heavier than the donor car and comes in at roughly 700 kilos (1,543 pounds). Therefore, the electrification only increased the weight by 10 percent.
The only engine drives the wheels with 240 PS (237 hp / 177 kW). The standard 0-60 mph (0-96.6 km/h) launch time is around 4 seconds. The top speed is unknown, but the traction battery capacity is 40 kilowatt-hours.
The car was specifically designed for the following use scenario: 20 minutes of continuous driving on the racetrack, 15 minutes of charging and 20 more minutes of track driving. The whole powertrain is said to be optimized for track use, and the charger is compatible with power sources rated up to 152 kW.
On the technical side of things, the EV Seven Concept has a limited-slip differential, adjustable shock absorbers and four-piston brakes. It also features regenerative braking, the one feature its petrol-guzzling counterpart lacks.
The live reveal of the one-off prototype will take place at this year’s Goodwood Festival of Speed.
