A New Zealand businessman has bought a $2.6 million Aston Martin supercar, one of only 77 the famous British marque will produce.

Aston Martin's NZ general manager Lee Small wouldn't name the buyer of the One-77 coupe, saying "he wanted something unique but he wouldn't want the publicity".

But it is known that the man flew to the carmaker's headquarters north of London to sign off on the car and its appointments with Aston Martin CEO Dr Ulrich Bez.

The One-77 - so named because only 77 will be built - is expected to land around the middle of next year. It has been described as the "ultimate expression of Aston Martin" and will be tailored to suit its owner's desires.

The One-77 is a carbon-fibre tub with aluminium body panels. Under the bonnet is a 7.3-litre V12 engine, a development with specialists Cosworth of the 6-litre unit used in the DBS, DB9, and new V12 Vantage.

The One-77 engine delivers 560kW of power and 750Nm of torque, making it the most powerful naturally aspirated road car engine in the world.

The two-door is expected to come off the production line weighing around 1500kg.

Aston Martin reckons the mix of power and weight will get it from zero to 100km/h in a tad over three seconds and on to a top speed of upwards of 330km/h.
