Porsche


Porsche........One of the most famous car manufacturers in the whole world. Its cars are cheaper, better and also the fastest cars when compared to others. The Porsche 997 Turbo is one of most powerful car ever built. But to us bad luck Porsche's are very rare in India and I heard that Porsche 911 Carrera S costs about 88 Lakhs. Specifications The Turbo version of the 997 series featured the same 3.6 L twin-turbocharged engine as the 996 Turbo, but this time it developed 480 PS (353 kW) and 620 N·m (457 ft·lbf) of torque. This was in part due to the 997's new variable-geometry turbocharger, which essentially combines the low-rev boost and quick responses of a small turbocharger with the high-rev power of a larger turbocharger. As well as producing more power and flexibility, the new turbocharger improved fuel consumption over the 996 Turbo. With these performance upgrades, it accelerates to 100 km/h (62 mph) in 3.9 seconds (3.7 with the Tiptronic transmission) and reaches a top speed of 310 km/h (193 mph). However, these are official figures and Porsche is notable for being conservative about their power and performance ratings. Motor Trend Magazine has clocked the 997 Turbo's 0–60 mph time in 3.2 seconds with the Tiptronic S transmission. The optional Sports Chrono overboost package increases torque to 680 N·m (502 ft·lbf) for short periods (maximum 10 seconds) but over a narrower rev range.
