The top speed of the Alpine A480-Gibson run by the Signatech team was four or five kilometres per hour lower than last year during Sunday's Le Mans test day as a result of changes to the Balance of Performance that have reduced its engine power by 40bhp.
Signatech team boss Philippe Sinault refused to criticise the BoP, saying that the onus was on the team to make improvements to its grandfathered LMP1 design.
