Starting from August 1st, all Porsche Boxsters come with a power gain with small improvements in performance. At the same time, changes have been made to models equipped with the Tiptronic S gearbox and the Sport Chrono Package.
Both Boxster and Boxster S engines are now equipped with VarioCam Plus, with variable inlet valve timing (VarioCam) and cam profile switching (Plus). The bucket-type tappets consist of one tappet inside another; the two tappets can be locked together hydraulically by a pin. These technologies allow tweaking of the engine's power/torque curve at the same time as optimising fuel economy at certain times.
The entry-level 2.7-litre Boxster receives a modest 5bhp increase in peak power, to 245bhp and a marginal improvement in fuel consumption. Even this model accelerates to 62mph from rest in 6.1 seconds on its way to 160mph.
Porsche has fitted the larger capacity 3.4-litre flat-six engine from the
Cayman S to the improved Boxster S. That means an increase in peak power from 280bhp to 295bhp. Maximum torque is 251lb.ft. The new Boxster S does the 0-62mph sprint in 5.4 seconds and will hit 169mph on a long enough road.
Other detail changes include a sportier calibration for the Tiptronic S automatic gearbox when it is combined with the optional Sport Chrono Package. Boxster buyers will also have the option to specify the same five-spoke 19-inch alloys as fitted to the Porsche 911 Turbo.
Deliveries start in August, with the regular Boxster at £33,170 and the Boxster S retailing at £39,850 (up from £32,640 and £39,160 respectively).
