Caterham’s Seventh All-Electric Concept Track-Ready

Caterham has unveiled the all-electric Seven EV concept to explore the possibility of equipping its vehicles with electric technology. Working with Swindon Powertrain’s E Axle, this concept produces 240bhp at 9,000rpm and 250Nm of instant torque. This is expected to allow it to get to 60mph in around 4.0 seconds. The EV Seven is also fitted with a limited slip differential, adjustable Bilstein dampers, regenerative brakes and quad-piston brake calipers.

The aim of the project was to replicate the performance characteristics of the current model without sacrificing anything by going electric. This means that the electrification keeps the car under 700kg with added accessories of less than 70kg. The overall design of the car remains the same as the battery is housed in the engine bay and transmission tunnel.

To make the battery technology suitable for road and track use it is designed for 20 minutes of driving on the track, then 15 minutes of 152kW DC charging to get another 20 minutes of track time. The 51kWh battery is immersion cooled, meaning the liquid is in direct contact with the cells to improve temperature control. This type of battery cooling technology is generally found in high-end computers that get very hot.

Bob Laishley, CEO of Caterham, says: “Any future EV design we produce must adhere to Caterham’s DNA: lightweight, fun-to-drive and driver-focused. The ultimate goal of this project is to create a vehicle with a zero-emission delta weight. and have passengers on board. We’ll never launch a ton of Seven – we’d rather not.”

“Building a Seven that can drive on Sunday morning is possible with current battery technology, but the challenge is for track use where energy consumption is very high. At the moment, immersion battery cooling is one of the best solutions in terms of dealing with cycles of fast charging and discharging that can be found on the race track.

Laishley says, “We have no plans to put the EV Seven into production at this stage – it’s a test bed to see how well the electric EV works for our customers’ specific use cases. We’re doing this project with our eyes open so we can learn how to deliver Caterham-specific features needed for the Seven. We will bring this to market in due course, when the next generation of battery technology allows, and that’s why now is the time for us to test this idea.
