During the first few years, the Lord Drayson owned team fielded a variety of E85-fueled machines in international events, including an Aston Martin V8 Vantage and a Lola LMP1 racer. In 2010 the latter became the first to win a major endurance race running on bio-fuel and also formed the basis for Drayson's most ambitious project yet; the all-electric Lola-Drayson B12/69EV.

Launched at the 2012 Low Carbon Racing Conference at the NEC in Birmingham, the B12/69EV was not built to any specific set of regulations, so it could explore the available technology to the fullest. While it shares the design with the Lola donor car, it does, for example, feature moveable aerodynamic devices, which are banned in most major series. These include the front dive planes, rear wing and rear gurney. When activated, drag is reduced by 30%. In keeping with the green philosophy, the actual body panels are all made from recycled materials.

The area previously occupied by a conventional Judd V10 is now filled with a bespoke electric drivetrain developed by Drayson Racing Technologies. It consists of no fewer than four YASA electric motors. These produce 160 kW each and the combined 640 kW is fed to the rear wheels through a single speed gearbox. The final drive ratio can be adapted to suit the particular needs of a circuit. Housed in a fully stressed carbon fibre box mounted between the chassis and final drive unit, is a 30 kWh battery. Helped by regenerative brakes, a single charge should allow the B12/69EV to run at full power for at least 15 minutes.
