British engineering consultancy Delta Motorsports has launched its Delta E-4 Coupé, a battery-electric two-door coupe with a range of 320 km on a single charge. Not that the car isn’t quick – it has a 0-100 kph time of under five seconds.

Built from the ground up, the E-4 – officially unveiled at Silverstone – features a carbon composite chassis, designed by Delta and manufactured by KS Composites, that weighs just 85 kg, which is two-thirds less than a comparable steel structure despite being designed to pass EU crash tests.

It’s powered by high performance direct-drive electric motors designed in partnership with Oxford University and its spin-out, Oxford YASA Motors. These produce over 120 hp each and well over 600 Nm of torque, while only weighing 23 kg. The batteries are mounted under the floor to help reduce aerodynamic drag.

Delta Motorsports, which was founded in 2005 by Simon Dowson and Nick Carpenter, has been working on the E-4 since 2007. Development of the prototype was supported by a grant for research and development by EMDA, an East Midlands regional development agency. A further five vehicles have been produced for the UK’s Technology Strategy Board’s Ultra Low Carbon Vehicle Demonstrator Program.

The E-4 Coupe will be taking part in this year’s RAC Future Car Challenge, which takes place in November.
