Drayson Racing Technologies announced recently its intention to break the current FIA World Electric Land Speed Record. The attempt will be made on June 25 at RAF Elvington in Yorkshire with a low-drag version of the Drayson B12 69/EV electric Le-Mans Prototype. Behind the wheel will be racing driver and former UK science minister Lord Drayson.
According to the first details we have the company aims for a top speed of about 200 mph – quite an increase over the current 175 mph record set by Battery Box General Electric in the United States which has stood since 1974.
This record has held firm for nearly 40 years due to the immense technical challenge of running an electric vehicle consistently and reliably at such speeds when weighing less than 1000 kg (2200 pounds).
Drayson B12 69/EV
The B12 69/EV was developed on a carbon Lola LMP1 chassis and is powered by 4 axial flux motors (2 per rear wheel) with integrated transmission. This system delivers a total of 850 horsepower and takes its power from a carbon battery cell integrated into the chassis.
However, for the land speed record attempt the output will be limited to 600 horsepower and for the battery the company will use a 20 kWh lightweight, high-power configuration. This way Drayson ensure a total weight of less than 1000 kg (2200 pounds.)
To challenge for the record some changes have been made to the set-up of the car and drivetrain that are consistent with racing at a low downforce circuit. This will give the B12 69/EV the traction to achieve maximum acceleration in the short distance available, sustain maximum speed over a measured mile and stop safely.
