Aston Martin V8 Vantage 4.7 (MY09) (2008 - date)

Speculation of a bigger engine for the V8 Vantage was extensive before the surprise announcement in late May 2008. The MY09 V8 Vantage was announced with an extensively re-worked 4.7 litre engine featuring both increased bore and stroke. Not sure if this engine will be seen in the N24 but I would expect so.

Externally the MY09 is identical to the pervious models. The interior centre console now matches that of the DBS (and MY09 DB9) complete with crystal ECU in place of a key and also receives a hard driver sat-nav system. Standard cars get new, unique 20 spoke 19 inch wheels. Of note is that the 'bee-sting' rear radio antenna has been deleted from the 4.7

The V8 Vantage transmissions have also undergone changes to improve performance and to handle the increased levels of power and torque. Both the standard manual optional Sportshift benefit from a modified clutch and flywheel, reducing clutch pedal efforts and delivering a 0.5kg weight saving, reducing the rotating masses within the powertrain, and hence increasing engine responsiveness. Sportshift has undergone a series of specific changes to broaden the capabilities of the gearbox. Changes include a revised control strategy, allowing the transmission, rather than the engine, to dictate how best the engine torque should be deployed to optimise performance and deliver power smoothly and consistently. The coupe now has fitted the stiffer suspension first seen on the Roadster and also has Bilstein dampers as standard.

I have seen this model described as N420 (since it has 420bhp) but I'm unsure that this is a factory designation. Unexpectedly, the clear rear light clusters as seen on the N400 models has not been carried over to the 4.7 and, apparently, it isn't easy to have them retro-fitted either.

Above, the new standard 20 spoke 19 inch wheel for the 4.7 litre V8 Vantage. Sports pack cars, receive the lightweight 5 spoke (I'd call it 10 spoke myself) 19 inch wheels as seen on pervious Sports Pack and N400 models.
