You hear Cosworth", what do you think? The Sierra Cosworth? The Ford Sierra Cosworth? The Ford Sierra RS Cosworth? Sure, that might have been the case 30 years ago, but Cosworth"s big project right now involves the Aston Martin Valkyrie"s engine. While the magic numbers are still under wraps, Cosworth has revealed the 6.5-litre V12 currently being created for the hypercar will have "two to three hundred more horsepower" than any other V12 road car engine, and that it"ll be the most poweful naturally aspirated road car engine ever. That ought to translate to around 1100bhp, given where Aston and Ferrari have taken nat-asp V12s up to now.
