The GBA engine was first road tested by Haas Lola's lead driver, World Champion Alan Jones in the new Lola THL2 at the Boreham Circuit in Essex just north-east of London on 21 February 1986. In freezing, snowy conditions (−6° Celsius) at approximately 10 AM, the V6 turbo, running a conservative 2.5 BAR boost setting, ran cleanly although the engine management electronics developed by Motorola in the United States and Cosworth had not yet been finalised and the engine ran with the same electronics that were used on the dynamometer. Also present at the test were Duckworth, Goddard, the THL2's designer Neil Oatley, the teams #2 driver Patrick Tambay and other staff from both Haas Lola, Ford and Cosworth.
