The world’s most powerful naturally aspirated engine in a road car. That’s the claim Aston Martin is making for its V12-shaped work of art tucked into the engine bay of another work of art: the One-77. It displaces 7.3 liters and spins out 750 hp and 553 lb-ft of torque. Getting to feel the thrill will probably be even more difficult than working out the variable valve timing, since only 77 examples of the car will be produced. And they’re all sold. But that hasn’t stopped AM from taking it to the Nrburgring for a thorough shakedown. Or perhaps it was just because the idea sounded too good to resist.
