The Brooklands Test Hill opened. Built to encourage use of the track for development and test work, it was 352 feet long and divided into three sections, starting with a gradient of 1 in 8, then 1 in 5 and the top third has a gradient of 1 in 4. Manufacturers to test both the ability of cars to climb steep hills and also of their brakes to stop them coming down used it.
