Modified rules for Le Mans Series from 2010

Updated: 

ACO, the body responsible for Le Mans racing, has published its new set of technical regulations for 2010. These will apply to the Le Mans 24 hour race as well as the LMS. And there are a few changes in store for Le Mans racing in general. The main idea is to boost competitiveness and make the events more attractive to the public. In LMP1, for example, steps will be taken to equal out the difference between diesel and petrol cars, with the latter being permitted more horsepower.

LMP1 will require further changes in vehicle construction while LMP2 will operate with reduced engine capacity. There are also new specifications concerning weight, with LMP1 diesels tipping the scales at a minimum 930 kilos – this season's 30kg handicap will be abandoned.


ACO Sport Director Vincent Beaumesnil: "We need to frame our rules in such a way that everyone has a level playing field. Given the global financial crisis, we wanted to keep vehicle modifications to a minimum, so that the current generation of cars can be used next season and perhaps even further into the future – as the contestants themselves have requested."

Safety is still the paramount consideration, and it was a stated objective that lap times should be kept above the 3 minute 30 seconds mark.
