So you bought an Aston Martin V8 Vantage with a 4.3 litre engine, not knowing the company would soon offer a stronger 4.7 litre engine down the line. And now you're feeling a bit inadequate. Well, good news for you.

Owners of a 4.3 Vantage are getting a new performance option. AM is making available a 20 horsepower upgrade to the engine in the form of a retro-fit induction system based on a similar unit in the DBS.

This system has two switching airbox-valves which open up at 5,500rpm to give an increase in air intake to the engine. To keep combustion under control, the engine ECU has been reprogrammed to improve ignition timing. These changes let the car better utilize high octane fuel, getting better overall performance.

Top speed of an Aston Martin V8 Vantage 4.3 with the engine upgrade is now 177mph (285 km/h). 0-62 mph (100 km/h) has been slightly improved from 4.7 seconds.

Also available is a retrofit of the Sports Pack option introduced with the new 4.7 litre V8 Vantage earlier in the year. The package includes better springs, Bilstein dampers, and lightweight forged-aluminum five-spoke wheels. This gives the car better response, and a lighter total weight.

The two options are fitted at dealerships, and prices are set locally.
