Drayson’s EV Speed Record Run On Michelin Le Mans Tires

Lord Drayson was successful in his bid to break the World Electric Land Speed Record for an EV type of car under 1,000kg by posting an average of 204.185mph over two runs completed within one hour.

Following the announcement earlier this month of a strategic partnership between Drayson Racing Technologies and Michelin, Drayson’s electric car made its performance runs wearing Michelin tires.

At the weekend, Michelin’s LMP1 tires helped Audi to victory in the 90th Le Mans 24 hour race, the second in a row for a hybrid car, and last night the same tires helped Drayson Racing’s electric race car reach a new electric land speed record.

The Drayson B12 69/EV electric Le Mans Prototype smashed the previous 175mph record, which had stood for 40 years, by 29.2mph. The record-breaking run took place at Elvington Airfield near York last night.

The Michelin tires used by Drayson Racing were confidential-specification LMP1 tires which have been developed for the sustained high speeds encountered in endurance racing and were designed in association with world-class endurance racing teams.

The sizes were 33/68R18 up front and 37/71R18 out back.

Michelin said the tire design chosen for the record attempt offered performance characteristics optimized for the conditions of the challenge and followed Michelin’s Total Performance ethos by managing to combine these often conflicting requirements.

They needed to offer low rolling resistance to reduce battery drain; high traction levels to enable the car to accelerate to maximum speed as quickly as possible; good stability to enable the car to safely run with minimal down-force; and excellent braking performance to ensure the car could be stopped safely before the end of the runway.

Michelin was quick to point that this isn’t the first record for an electric vehicle fitted with Michelin tires. In 1899 La Jamais Contente broke the 100km/h barrier fitted with the Company’s pneumatic tires when most cars were still running on solid tires.
