Harry Metcalfe of evo magazine gets a chance to spend a day with Aston Martin’s current ultimate expression of the car, the One-77. We haven’t really seen too many of the details of the One-77 because Aston Martin didn’t let any reporters drive it since the entire production run was only 77 units; so this video is a bit of a treat. The One-77 is powered by a 650 horsepower naturally aspirated 7.3 liter V12 that starts out as the standard Aston Martin 6.0 liter bored out with special cylinder liners. Metcalfe says the variable valve timing and lighter flywheel give the engine a completely different attitude than the standard engine making the One-77 an edgy high rpm horsepower car. We also get a view of the beautiful carbon fiber enclosed engine bay and the pushrod suspension at all four corners. It’s another intimate look at one of the most exquisite cars in existence.
