The new Porsche 918 Spyder concept synthesizes racing abilities and electric mobility, offering an amazing suite of qualities: emission levels of about 70g CO2 per kilometer, when utilizing an average of 3 liters/100 kilometers. Its fuel consumption is about 78 mpg. Also, weighing only 3,285 (1,490 kg), the prototype offers supercar performances such as: accelerating from 0 to 100 km/h in just 3,2 seconds and a maximum speed of 62 mph (320 km/h). More than that, it scored a less than 7:30 minutes record on the Nurburgring track, outranking the Porsche Carrera GT – the pinnacle of the German company’s series.
Porsche 918 is one of the three hybrid propulsion models which have been revealed at the Geneva Motor Show. This trio of the new Cayenne S Hybrid, the 911 GT3 R Hybrid and the 918 Spyder Hybrid concept, demonstrates not just the qualities of this new technology, but also Porsche’s innovative power, as a pioneering force in hybrid propulsion systems.
The new two-seated 918 Spyder model consists of a hybrid plug-in system, with a V8 engine that operates with the aid of air-cooled lithium-ion batteries, generating over 500 hp, at a maximum of 9,200 rpm, and 2 electric motors, placed on the two axes, with a maximum power of 218 hp (160 kW). The V8 engine is a version of the 3,4 liter one which is included in the RS Spyder racecars. Batteries also recharge while braking, using KERS, and while coasting. Chassis materials include carbon fiber reinforced plastic and magnesium and aluminium for a lower weight.
In the electric mode, 918 Spyder is capable of driving on a 25 km track. In hybrid mode, the car uses both the electrical engines and the fuel engine, depending on driving conditions, offering both great efficiency and dynamic ultra-performances. When you are in Sport Hybrid Mode, the car uses both propulsion systems, but tends to improve performance. Most of the generated power is directed to the back wheels. When in Race Hybrid Mode, systems are focused solely on pure performance, at the highest standard of track racing, pushing the engines to their limit. Read the rest of this entry »
If the best classic cars have great looks, are great to drive and are exotically rare, then the Porsche 924 Carrera GT is up there with the best of all classic cars. The 924 Carrera GT had supercar looks, sounds and scats like a Carrera too.
Had anyone else built the 924 it probably would have been hailed as a brilliant little sports car. It was strong, remarkably efficient and deceptively quick, making the most of its rather modest two-litre engine but in the opinion of Porsche fans it was thought to be a bit timid. Then the incredible 924 Carrera GT appeared, setting the critics back in their seats. Not only was the 924 Carrera GT stunningly quick, it had style and street fighter aggression.
Of the 406 units built 200 are earmarked for Germany and 75 for the UK, which was about the only place you could still get full value from a Carrera. A speed of 130 mph at the 6400 rpm rev limiter then, you shift into 5th, and 150 mph is well in sight. This is a true 150 mph automobile which will accelerate from zero to 60 in less than seven seconds, despite a turbo that doesn’t really go to work until 3000, coupled to typical Carrera gearing not designed for drag racing.
it is not enough then as it is now simply to make a powerful monster; fuel consumption figures were noticed then as well. Porsche fitted a digital ignition control to keep the engine at max efficiency, and improved aerodynamics. With and eye for detail work on the body keeps, the GT is the same as the Carrera’s plain cousin, despite wide fenders, extra scoops a larger rear spoiler lip helps considerably. In a combined European consumption test, readings were taken at a steady 55 and 75 mph and averages those figures with a city reading, the Carrera GT received a rating of 25.8 mpg against 26.1 for an unblown European 924!
The hood scoop was the first indication of a surprise in the engine compartment that contained a new configuration. Compression is raised on number to 8.5:1, and the scoop leaded to a flat intercooler, The engine reaches is 210 horsepower potential at 6000 rpm. The power-plant is coupled to a heavy shifting five-speed, with top four in an “H” and fifth place in a dogleg to the left rear. Gear speeds are 35-65-100-130 and beyond.
The ride is firm to the point of bounce on the rougher surfaces,but if you let it seek out its own path, it can be blindingly fast and a ball to drive. 215/60 tires help with stability, and even lower section 55/50 series tires are optional. Fender flares were made of the same bounce-back material as a 928 nose, warding off small blows. The 924 Carrera GT was available in black or Guards Red, with “Carrera” embossed on the front right wing. Read the rest of this entry »
