Hi OP, I hope you don't mind that I'm adding some content to your thread, I frequent a site called Gizmag, they have latest of everything Tech
related, to date, they have over 18,000 articles.
Here is a small sampling from the article on this new car, visit the link for the rest including the origins of it's Hybrid unit,
from the article;
Porsche's hybrid 918 Spyder is a 770 bhp supercar that can top 320 km/h (200 mph), accelerate to 100 km/h (62 mph) from standstill in under three
seconds and lap the Nurburgring Nordschleife circuit in seven minutes 22 seconds. The largely-carbon-fiber 918 Spyder will hit showrooms before the
end of 2013, with pricing beginning at around US$1 million. It's all standard fare for a supercar except for one small thing - its fuel consumption of
3.0 l/100 km (94 mpg).
Porsche's hybrid 918 Spyder first broke cover in 2010, creating a sensation with its combination of 500 bhp V8 plus three electric motors totaling 215
bhp for a total of 715 bhp.
At that time, the car was officially quoted as running 0-100 km/h in 3.2 seconds, having a top speed of 320 km/h (198 mph) and was reported to have
done a lap of the Nordschleife Nurburgring circuit under 7:30 minutes.
The order books were officially opened for the 918 Spyder in March 2011 with an asking price of US$845,000 and the news that no more than 918 units of
the new two-seater supercar would be produced, beginning in September 2013.
Main propulsion: the eight cylinder engine
The main source of propulsion is the 4.6-litre, eight cylinder engine delivering more than 570 hp of power, which was directly derived from the power
unit in the successful RS Spyder and explains why it delivers engine speeds of up to 9,000 rpm. Like the RS Spyder’s racing engine, the 918 Spyder
power unit features dry-sump lubrication with a separate oil tank and oil extraction. In order to save weight, the four extraction pumps are made of
Further extensive lightweight design measures resulted in, for example, titanium connec- ting rods, thin-wall, low-pressure casting on the crank case
and the cylinder heads, a high- strength, light-weight steel crankshaft and the extremely thin-walled, alloy steel exhaust system. The result of the
weight and performance optimisations is a power output per litre of approx. 125 hp/l, which is significantly higher than that of the Carrera GT (106
hp/l) and outstanding for a naturally aspirated engine.
That's just a very small amount of info from the article, for those of you that love this kind of stuff, I suggest a visit to the website, they go
into a comparison to the famous "917s", that was Porsche's race car that produced about 1200 HP, I saw one of those things on the Laguna Seca race
track in Monterey Ca, it shook the grandstands when it came by, just awesome.
There's lots of stuff to see on that site for any Tech minded person, Enjoy
