Increased horsepower from 3.8-litre engine
The engine of the 911 Sport Classic features a newly-developed resonance intake system with six switching butterflies. The 3.8-litre flat-six power unit with Direct Fuel Injection is based on the engine already featured in the 911 Carrera S. However, working carefully on various details in the intake manifold has allowed Porsche engineers to increase engine output and torque, particularly in the medium speed range. Combined with modified cylinder heads, a new intake system and new engine management, the upgrades serve to raise engine output by 23 hp to 408 horsepower.
A particular highlight is the new, variable resonance intake system featuring six vacuum-controlled flaps switching between a more power- and a more torque-oriented geometry. Opening or closing simultaneously as a function of engine speed and the position of the throttle pedal, these flaps optimize the oscillation of air in the intake manifold for a better cylinder charge. The result is an optimum supply of fresh air into the combustion chambers under all conditions, maintaining maximum torque and optimizing the torque curve - together with an increase in engine output.
The exhaust system specially developed for this unique model provides exactly the right exhaust gas counter-pressure, the high-gloss tailpipes with their classic grid inserts likewise purpose-built for the 911 Sport Classic. Beneath the rear lid, on top of the engine, lays a carbon fiber air filter housing to add a particularly powerful look.
As is typical of Porsche, the increase in engine power is achieved with maximum efficiency, and the 911 Sport Classic maintains the full fuel economy and CO2 emission ratings of the 911 Carrera S.
Sports-oriented chassis
Clearly reflecting its name, this limited edition model is consistently sporting in every respect, with appropriate equipment and exactly the right dynamic set-up. The Sport Chrono Package Plus, for example, comes as standard and the 911 Sport Classic is available only with a manual gearbox. Furthermore, the gearshift travel has been reduced, and offers a perfect match for the car.
In addition to its Porsche Active Suspension Management (PASM) sports suspension and ride height lowered by 20 mm (0.79"), the 911 Sport Classic also comes with a rear limited slip differential for very dynamic performance on the road.
Yet another standard feature in the 911 Sport Classic is Porsche Ceramic Composite Brakes (PCCB). Cross-drilled and inner-vented, these composite ceramic brake discs measuring 350 mm (13.8") in diameter weigh approximately 50 per cent less than comparable brake discs made of grey-cast iron, providing a reduction of unsprung masses beneficial above all to the car's driving dynamics. In conjunction with the likewise purpose-built brake linings, the ceramic brake discs immediately build up a very high and in particular consistent frictional coefficient whenever required. In comparison with conventional brake discs, surface abrasion is limited to a minimum thanks to the extremely hard surface of the ceramic discs. The service life of the PCCB brake system, as a result, is very long indeed.
Iconic wheel design
One of the most striking features on the 911 Sport Classic is the new 19-inch Sport Classic wheels with their rim centre finished in high-gloss black paint. Bearing a clear resemblance to what must be the most classic Porsche wheel of all times - the world-famous Fuchs rims designed by Porsche in the Sixties and subsequently produced by Fuchs - the new wheels are nevertheless simply perfect for today's world, adding to the striking look of this small, exclusive series.
