2009 Porsche Boxster S

Displacing 2.9-litres, the engine of the Boxster develops 255 bhp (188 kW) in the Boxster, an increase of 10 horsepower over the prior 2.7-litre model.

The 3.4-litre power unit in the Porsche Boxster S now features Direct Fuel Injection, and delivers 310 bhp (228 kW), up by 15 bhp.

An impressive power-to-weight ratio imbues the two Boxster models with optimum driving dynamics. For example, with the new six speed manual transmission fitted as standard, the Boxster accelerates from 0-62 mph (100 km/h) in 5.9 seconds. And the Boxster S, when fitted with PDK transmission and Launch Control (featured in the optional Sports Chrono Package Plus), accelerates from 0-62mph (100km/h) in 5.0 seconds.

When combined with PDK, the new 2.9-litre engine fitted to the Boxster clearly breaks through the 30.0mpg fuel consumption boundary. Indeed, the figure of 31.0mpg (9.1 litres/100km) is approximately 10 per cent better than the previous model with the Tiptronic S automatic transmission. Increasing fuel economy by an even more significant 15 per cent to 30.1mpg (9.4 litres/100km), the 3.4-litre Boxster S with PDK offers an even greater saving over its predecessor with Tiptronic S.

In parallel with the improvement in fuel economy, so emissions of the engines have decreased also. Depending on model, emissions have been reduced by up to 16 per cent. The Boxster with the standard six-speed manual gearbox emits 221g/km CO2, and 214g/km CO2 when fitted with PDK. The Porsche Boxster S manual emits 223 g/km CO2, and 221 g/km CO2 with PDK.

Significantly, these developments move every Boxster model – whether manual or PDK – into Band F for Vehicle Excise Duty and company car taxation purposes.
