The Aston Martin Valkyrie has been a surprise element from a long time. This ambitious project from the British marque is essentially a road-legal version of a Le Mans prototype racer. The $3.3 million hypercar has been teased on multiple occasions and always left us so close to the real thing. Now, Cosworth has confirmed that the Valkyrie will have the world’s most powerful N/A engine ever equipped in a street-legal car. The engine supplier said that the Valkyrie will be offered with an all-atmosphere V-12 unit producing around 1,100 horsepower!
