Driving force: the Cosworth V12 powering Aston Martin's Valkyrie
Aston Martin’s Valkyrie is one of the most hotly anticipated supercars of the decade, and its Cosworth V12 powerplant has been hailed as the ultimate expression of the internal combustion engine. Jon Excell reports
Even behind two hermetically sealed doors, three layers of bullet-proof glass, and several layers of acoustic damping, the scream of the chunk of precision-engineered metal strapped to a dynamometer deep inside the HQ of UK powertrain specialist Cosworth is frighteningly impressive.
