Speedster E Development

Developing a cutting edge electric drive train for our 356 Speedster chassis

Speedster E - Designing our electric Chesil

A changing world

The last 10 years have seen a monumental shift in the worlds views on personal transport. End of life recycling, low emissions and energy consumption now all play a key role in the buying process. It is too easy to say that niche vehicles like our 356 Speedster are immune from this. 

At home in town and open road

We believe that city centres are the perfect place to use and be seen in a Chesil and that, increasingly, is going to demand an emission free propulsion system! Although the city centre would seem to be the ideal home for the Speedster E, it will be just as happy out in the countryside and on longer trips.

Range and dynamics

Weighing in at just 950 kgs the Speedster E's 36 kw battery pack will give a nominal range of between 175 and 200 miles before requiring a 45 minute CCS* re-charge.

The motor produces 120 kilowatts or 160 bhp. A sprint to 60 mph will take just 7 seconds, but it is the in gear performance where the car really shines. EV drive trains provide instant peak torque so there is always power on demand.

Chassis, steering and brake design have come a long way since the 356 was designed and the Speedster E's chassis has been created from the ground up around our EV drive train.  This  ground up re-design has allowed us to use rack and pinion steering, all round disc brakes and fully independent suspension.

Our aim is to produce a totally analog, electric sports car that is not only thrilling to drive, but stops and handles in a predictable modern manner.
