Delta E-4 Coupe - gull-winged electric prototype - Oxford to London on half a charge
Born at Silverstone, the Delta E-4 Coupe is a compact 4-seater with optimised aerodynamics, mechanical efficiency and minimal weight. Delta Motorsport believe these should be the fundamentals of energy consumption in road cars. The torque-rich electric motor was developed by an Oxford University spin-off company and the 2 or 4wd E-4 has phenomenal performance and handling. The focus on achieving a viable selling price poses a whole new set of challenges.
The distinction between ULEV (Ultra Low Emissions Vehicle) and ULEnV (Ultra Low Energy Vehicle) is a subtle but important one. Powering an Audi Q7 or a BMW X5 from batteries would turn either into a low emissions vehicle, but we believe this is missing the point since they would still consume a huge amount of energy in any journey. All this energy ultimately has to come from somewhere, even if it’s from renewable sources, and we believe that over the next few years a sharper focus will gradually fall on reducing all cars’ energy consumption.
Building a car that consumes significantly less energy will allow us to consider a wide variety of choices for energy storage, from hydrogen to batteries. We’re not ruling anything out however – we’ll also consider gasoline and diesel versions in the future if we feel there’s a suitable market. The most important thing is to get the fundamental architecture of the vehicle right, and the rest will follow.
