Aston Martin is wrapping up production of the iconic DBS grand touring car with the 770 Ultimate, an extensively reengineered special edition that arrives this fall.

The supercar is powered by a revamped version of Aston’s 5.2-liter twin-turbo V-12, now rated at 770 hp. The suspension and chassis have also been tweaked to sharpen performance.

Pricing starts at $391,486 for the coupe and $419,937 for the Volante convertible model, Aston said, including shipping and at current exchange rates.

Aston is building just 499 units, all of which have been sold, the company says.
