Aston Martin One-77 — spec data and generation history.
Aston's first proper hypercar — carbon-fibre monocoque, hand-formed aluminium body, 7.3 V12 NA (750 bhp) developed by Cosworth from the 6.0 V12. Hardest road-Aston engine ever built — naturally-aspirated, dry-sumped, push-rod inboard suspension. 77 cars, all sold before launch. Q-by-Aston bespoke trim, exposed carbon spine on the dash. Q-Series followed (One-77 Q) for serious specifications. The car that put Aston back on the hypercar map after the Vanquish.
