Porsche has released the first official pictures of the new Boxster, due to go on sale in the UK from 27 November.

The new Porsche Boxster offers increased power from its 2.7-litre and 3.2-litre flat-six engines in addition to a host of other developments introduced with the intention of keeping the mid-engined sports car at the top of its class.

The 2.7-litre six-cylinder engine now develops 240 bhp, 12 bhp more than previously. The performance of the Boxster S, which will be launched simultaneously, has also been increased to 280 bhp from 260 bhp, while cubic capacity has remained unchanged at 3.2 litres. The Boxster needs only 6.2 seconds to sprint from 0-62 mph, while the S model achieves this in 5.5 seconds. Top speed is 159 mph for the Boxster and 167 mph for the Boxster S.

In addition to the power increase, a revised chassis offers greater driving pleasure and at the same time enhanced active and passive safety. Larger wheels and a wider track emphasise the further development of the body shape and symbolise the increase in performance of the two models. The new nose shows the relationship with the 911 series but still features the characteristic Boxster appearance. The new lighting concept with the separation of main headlamps and front lamps with integrated fog lamps exemplifies this.

When viewed from the side, the larger rear air vents, the bold door sills, the larger window glass area, and the newly-designed, larger diameter wheels are dominant. The 2.7-litre Boxster now has 17-inch wheels as standard, while the Boxster S features 18-inch wheels.

The new Boxster also features a revised five-speed manual transmission, with the S model benefiting from a new six-speed gearbox. The gearshift has been revised for both transmission variants so that shift travel is now considerably shorter. Both vehicles can be optionally equipped with the five-speed Tiptronic S transmission.

The Boxster is the first roadster in the world to offer passengers protection against lateral impact using head airbags. In combination with a thorax airbag, concealed on the outer side of the backrest, the airbag deploys from the side window rail of the door and provides a high level of protection for the head.

The Porsche Boxster will be priced at £32,320 and the Porsche Boxster S at £38,720.
