One-77 will only be produced in limited numbers, or else, the 77 its own name mentions. It will be powered by a tweaked V12 engine, the same one used by DBS, but increased to 7.3 litres instead of 6 litres. Cosworth has given Aston Martin a help and the V12 is 25% lighter than the original engine. It can also produce over 700 bhp, what will allow the car to surpass 360 km/h and to go from 0 to 100 km/h in about 3.5 s. All this in a vehicle that weights 1,500 kg and is sophisticated as any other Aston. We can't wait to see it reach the streets.
