Now a days we all talk about V8 engines. Every sports car today has it. But what exactly to an engineer a V8 engine means? What does 8 cylinders provide that 6 cylinders engine are not able to provide except power and all that general stuff???? This article will talk about it.
New Porsche 911 with Direct Fuel Injection and Double-Clutch Gearbox
Stuttgart. Starting on 5 July, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is introducing the next generation of the 911 model series. The four new models – two Coupés and two Cabriolets – with classic rear-wheel drive offer an even higher standard of dynamic performance thanks to their all-new flat-six power units displacing 3.6 and, respectively, 3.8 litres. And the introduction for the first time of direct fuel injection on a Porsche sports car, together with the optional double-clutch gearbox Porsche-Doppelkupplung (PDK), makes the new 911 even more sporting and dynamic.
At the same time these new technologies enhance the already outstanding efficiency of the 911 to an even higher level than before: Featuring PDK, the Carrera Coupé offers outstanding fuel economy of 9.8 litres/100 kilometres, equal to 28.8 mpg imp. And with all new Carreras remaining significantly below the fuel consumption benchmark of 11 litres/100 kilometres, equal to 25.7 mpg imp, CO2 emissions are down by up to 15 per cent.
Maximum output of the 911 Carrera with its 3.6-litre power unit is up by 20 bhp to 345 bhp (254 kW). Output on the 911 Carrera S with its 3.8-litre power unit is equally impressive, up by 30 bhp to 385 bhp (283 kW). With this extra power, the Carrera S Coupé now offers a top speed of slightly over 300 km/h or 186 mph.
The new generation of the 911 is available for the first time with the new Porsche-Doppelkupplung (PDK), Porsche’s double-clutch gearbox. Offering no less than seven forward gears, the new gearbox combines the driving comfort of a converter automatic transmission with the dynamic gearshift of a sequential racing gearbox. And since PDK also boasts an automatic gearshift function, it replaces the former Porsche Tiptronic S automatic transmission on both the Carrera and Carrera S. Through its optimised and adaptive gearshift programs, PDK improves the car’s acceleration and reduces fuel consumption to a level even lower than before.
Porsche developed this gearshift principle featuring two clutches to shift gears without the slightest interruption of traction and pulling power and without even the slightest break in between gears no less than 25 years ago for motorsport. Porsche works drivers benefiting from this technology were able to accelerate faster than their competitors and keep both hands on the steering wheel while shifting gears, thus avoiding even the slightest distraction while shifting. The pioneering achievement from back then now gives the new 911 Carrera even better performance: Equipped with seven-speed PDK, the Carrera S Coupé accelerates in 4.5 seconds from 0-100 km/h, another 0.2 seconds faster than with a manual six-speed gearbox. And the customer in search of optimum driving dynamics even has the option to combine PDK with Porsche’s optional Sport Chrono Plus including Launch Control. The result is high-speed acceleration free of slip from a standstill and a racing gearshift, with the car accelerating to 100 km/h in a truly outstanding 4.3 seconds.
The new generation of the 911 stands out clearly at first sight through innovations in design both front and rear as well as new lights with LED technology. LED daytime driving lights and bi-xenon headlights now standard on all new models in the Carrera range give the silhouette of the 911 even more distinctive style and a truly unique look, interacting with new LED rear lights to ensure an unmistakable and striking appearance also at the rear. And as a further safety option, Porsche now also offers Dynamic Bending Lights on all models.
Prices start at Euro 69,600.- for the Carrera (Euro base price). The Carrera Cabriolet and Carrera S both retail at Euro 78,000.- (Euro base price), and the Carrera S Cabriolet is entering the market at Euro 88,000.- (Euro base price).
