The limited-edition Ultimate marks the end of the line for the current DBS.

Aston Martin is presently in the final stages of developing the next-generation DBS sports car. To commemorate the current model before it drives off to the big parking lot in the sky, Aston has announced it will build a special Ultimate edition with a production run of just 100 examples.

Distinguishing the Ultimate from the "standard" DBS are a bevy of aesthetic upgrades inside and out. Exterior changes include Diamond Black wheels, Zircotec-coated exhaust pipes, carbon-fiber mirrors and and taillamp trim, a dark finish grille, smoked taillight lenses and brake calipers painted in the buyer's choice of red, yellow or black. Ultimate badges will of course be part of the package, and three unique exterior colors will be on offer: Silver Fox, Quantum Silver, and Carbon Black.

The cabin benefits from quilted Black Obsidian leather seats with red stitching, quilted synthetic suede headliner, DBS headrest embroidery and red-leather trim on the shift paddles.

No revisions are planned for the 510-horsepower 5.9-liter V12, but unlike in recent DBS special editions, a six-speed manual gearbox will be available as an alternative to the six-speed automatic.

The Ultimate edition will command $287,576 in coupe form and $302,576 for the drop-top Volante; for those who haven't committed DBS pricing to memory, those figures represent sizable $14,301 and $15,666 increases over the standard models. It is estimated that 25 to 30 examples will be offered for sale in the United States in late 2012.
