Caterham unveiled the EV Seven today, showing us its technology development plan for a future all-electric Seven.
The concept will test the feasibility of a lightweight electric Seven and allow Caterham to move one step closer to launching an electric model that will be just as driver-focused as its petrol counterpart.
The EV Seven is built in partnership with Swindon Powertrain, and is based on the larger Seven chassis. This means that its length reaches 3,350 mm, its width 1,685 mm, and its height 1,115 mm. The weight of the car is estimated to reach 700 kg, which was an increase of almost 70 kg over the existing Seven 485.
It is powered by a Swindon Powertrain electric motor, producing 240 hp and 250 Nm of torque, which is fed by a 51 kWh battery (40 kWh useful), with 0-100 km/h coming in almost 4 seconds, while the final will reach 210 km/h.
Battery cooling uses dielectric fluid, in this case provided by Motul. The liquid is in direct contact with the cells allowing for better thermal management during charge and discharge cycles. This cutting-edge technology is at the forefront of battery electric vehicles and, until now, has typically been used to cool supercomputers that generate massive amounts of heat.
The battery is located in the engine compartment and in the transmission tunnel, and is capable of fast charging with DC up to 152 kW. In addition, the EV Seven features a limited-slip differential, Bilstein adjustable shocks from the Seven 420 Cup, four-piston brake calipers, and brake energy recovery.
The EV Seven can be driven on the track for 20 minutes and recharged in 15 minutes with enough energy to drive for another 20 minutes. The EV Seven will make its debut during this year’s Goodwood Festival of Speed in July, while another Caterham electric concept will be revealed later this year.
