Aston Martin DB9 Volante, Aston Martin introduced a  revised version of the company’s critically  acclaimed Aston Martin DB9  at the 2008 Geneva Motor Show, which includes  significant enhancements  to standard specification. These changes  include a revised version of  Aston Martin’s 6.0 litre V12 engine to  deliver improved power and  torque. Peak power of 470bhp (350kW) –  increased by 20bhp (30Nm) – is  now reached at 6,000rpm, resulting in a  power to weight ratio of 267bhp  per tonne (199kW/tonne) – an increase of  11bhp per tonne over the  existing Aston Martin DB9.
Peak torque of 600Nm is delivered at 5,000rpm, providing even more   accessible power for the driver, as well a greater performance feel   overall. Accordingly, top speed is now 190mph (306km/h) and the   benchmark 0-60mph time improves by 0.3 seconds for the Touchtronic   transmission – which benefits from a new valve box and integrated   transmission controls to achieve quicker gear shifts – to 4.6 seconds   and by 0.1 seconds to 4.6 seconds for the manual gearbox.
The latest Aston Martin DB9 also  incorporates a series of chassis  developments for both the Coupe and  Aston Martin DB9 Volante derivates.  Bilstein dampers are introduced in  addition to revised upper suspension  arms and retuned suspension bushes  to deliver improved ride quality;  aiding greater refinement in the  Aston Martin DB9 Volante and an  enhanced sporting feel in the Coupe.  The Aston Martin DB9 Volante also  benefits from revisions to the front  shear panel which increases  torsional rigidity by 10%, further  improving refinement.
The Aston Martin DB9 manages to combine  all facets of style, quality  and usability of a traditional Aston  Martin without relying on  retrospective detail or design. Accordingly,  styling changes to the  revised Aston Martin DB9 are subtle, reflecting  the car’s timeless  design and understated elegance.
Exterior styling changes include the  introduction of a new standard  19” 10-spoke alloy wheel, new door  mirrors and a revised anodised  aluminium five-bar grille. In the cabin  changes include a new centre  console constructed from die cast zinc  with a painted iridium silver  finish and the introduction of a new  Emotion Control Unit (ECU) – first  seen on the Aston Martin DBS in  2007. The ECU – constructed from glass,  polished stainless steel and  polycarbonate – replaces the key used  previously for the Aston Martin  DB9.
The innovative Aston Martin DB9  introduced an exciting new era for  Aston Martin. The 2+2 sports car set  new standards in its class due to  its astonishing combination of  technology, agility and design. The car  marked the beginning of a new  era for Aston Martin and became the first  car to be hand-made at the  company’s state-of-the-art facility in  Gaydon, Warwickshire.
Sales of the Aston Martin DB9 started in  spring 2004, and to date,  more than 10,000 examples have been produced  and delivered to customers  around the world – surpassing the Aston  Martin DB7 as the most  successful Aston Martin of all time. Deliveries  of the updated Aston Martin DB9 begin during quarter two  2008, with  prices from £113,950 for the Aston Martin DB9 Coupe and  £122,950 for  the Aston Martin DB9 Volante.
