The Hethel Test Track is 2.2 miles in length and can be divided into 2 separate circuits - North and South. The total land occupied by the track and surrounding run-off areas covers approximately 30 acres of the 50 acre Group Lotus site.
The test track meets FIA specification, but is not formally FIA approved, as it is used for testing purposes only.
