As a result, 911 Carrera S with the PDK dual-clutch transmission in Sport Plus mode completes the 0-100km/h sprint in 4.0 seconds (0-60mph in 3.8 seconds), an improvement of 0.3 seconds over the regular PDK Carrera S model and 0.1 seconds when fitted with the Sport Chrono package.

Porsche says the kit also increases the top speed by four km/h (~3mph) to 306 km/h (190mph) with PDK and to 308 km/h (191mph) with a seven-speed manual gearbox.

The main elements of the Powerkit are special cylinder heads with different camshafts, a new variable resonance intake system design with six air flaps and a resonance flap, plus an additional center radiator to keep temperatures under control and a sport exhaust system with two sets of twin tailpipes.

The Powerkit also includes the Sport Chrono package as standard along with a titanium colored engine cover and carbon inlays.

To mark the 60th anniversary of the first Porsche Clubs in Germany, the Stuttgart sports car maker has readied a special edition version of the 991 aptly named the 911 Club Coupe.

Based on the latest 911 Carrera S, the new model is available exclusively to Porsche Club members with production limited to only 13 units, one of which will remain with Porsche.

All 13 examples of the 911 Club Coupe are painted in a classic “Brewster Green” hue and feature the standard Sport Design Package that adds a new front bumper and a ‘ducktail’ rear spoiler, while riding on 20-inch SportTechno alloy wheels.

The interior package includes dark brown leather sport seats with decorative beige stitching, illuminated door entry guards bearing the model designation and anniversary logo, and an aluminum trim kit with a personalized laser engraving “911 Club Coupe – personally built for” and the name of the client.

Under the sheetmetal, the standard PASM sports suspension allows the driver to drop the 911’s ride height by as much as 20mm, while the newly developed Carrera S Powerkit provides an extra 30-ponies lifting output from 394hp (400PS) to 424hp (430PS).
