Aston Martin has revealed the race car with which it will aim for its first overall victory in the Le Mans 24 Hours in more than 60 years, reports Autocar.

Based on the road-going Valkyrie, it has been developed to the Le Mans Hypercar (LMH) rulebook.

It will be the only car in the top flight of endurance racing to be powered by a V12 engine; all other competitors use either a V8 or a V6.

It will also be one of just two naturally aspirated engines in the class, joining the V8 of the Cadillac V-Series R.

The Valkyrie’s hybridized 6.5-litre Cosworth V12 has, however, been redeveloped to better suit endurance racing.

It's detuned from 1140bhp down to the 680bhp mandated by the rulebook.

Meanwhile, the Valkyrie’s bodywork has been redesigned to allow any damaged components to be removed and replaced more quickly, as well as for better aerodynamic performance.

A pneumatic jack system has been added to the chassis to speed up tire changes.

The car will be entered into this year’s FIA World Endurance Championship (WEC) and the US-based IMSA Sportscar Championship.
