Porsche has boosted the Boxster and Boxster S, with more power and more torque, and a tweaked Tiptronic S auto transmission.
The entry-level 2.7-litre engine now develops an additional 5bhp, bringing max power to 242bhp. Torque is also up (from 199 to 201lb ft), but fuel consumption now 1mpg better, at 30.4mpg average.
The Boxster S engine has been increased from 3.2 to 3.4 litres, and now develops 291bhp 15 bhp more than its predecessor – and 251lb ft of torque (up 3lb ft), taking a tenth of a second off the 0-62mph time, and top speed up to 169mph.
The power and torque increases are largely thanks to the introduction of VarioCam Plus valve control, with variable valve timing and changeover valve lift.
The revised optional Tiptronic S transmission has new hydraulics and electronics, plus variable shift programs, making for swifter changes, especially in conjunction with the Sport Chrono Package.
Other changes to the Boxster range include the improved access to the coolant and engine oil filler caps, making the rear boot more practical, and the option of new 19-inch forged alloy two-tone wheels that were developed for the new 911 Turbo.
The upgraded roadsters are available from August.
