Just how fast is this thing? Well, Porsche says the 918 Spyder Concept hits 100 km/h (62 mph) in less than 3.2 seconds, and it blasts to a top speed of 198 mph. Not only that, it laps the Nürburgring in less than 7 minutes 30 seconds, which means it’s even faster than the hallowed Carrera GT.

The 918 Spyder Concept is powered by a high-revving V-8 related to the 3.4-liter in the Porsche RS Spyder racing car. In 918 Spyder form, this mid-mounted engine revs to 9200 rpm and produces more than 500 bhp. Electric motors at the front and rear axles add an additional 218 horsepower to the output. The V-8’s power, and that of the rear electric motor, reaches the Spyder Concept’s rear wheels via a 7-speed PDK gearbox. The drive to the front wheels is pure electric, via a fixed ratio. The liquid-cooled lithium-ion battery pack behind the cockpit can be charged at home, or by brake regeneration.

The word ridiculous comes to mind. But in a good way. A very overengineered, yet still good... way. And from the tiny pictures you posted, it looks pretty good. A little busy, but good. I kinda like it.

Looks like Spyker had a hand in designing it...which means I f***ING LOVE IT.And it's about time a sports car manufacturer makes a serious Electric-Powered AWD system. Lets just hope it doesn't way 4,000 lbs.

I was interested until I got to the "electric motors" part.

Think of how much MORE awesome that thing would be if they left the electric motors and batteries on the ground. These stupid "performance hybrids" are fine from companies like Lexus. But I expected better from Porsche.

ehh...sounds more like KERS than hyrbid.

it's kinda neat.

[jbracy7]

my qustion why 9200 rpm redline for a v8 thats kinda crazy.why does it need to rev that high. i think this is porsche's "look we can do green too" car i wonder what the price is going to be 100k+ 200? 300?..... bet the leaf could bet it on electic alone... jk

IT in NO way resembles KERS...It's a hybrid system with batteries being charged by the engine with what seems like power on demand depending on traction and throttle conditions.If done correctly...it could really blow the competition out of the water. IF it's buggered up...Porsche will have an overweight quick AWD Prius.

The perfect locomotive system for a car would be all four wheels powered individually by electric motors of sufficient power. Supplying those motors with juice could either be full electric via a fuel cell or a small diesel hybrid system. Even steam power would work in this case. Combine this with a suite of sensors, super-fast computing, a good chassis, and light weight and you WILL have the fastest car on the road.

This is assuming all you care about is outright speed and effeciency...which is only one part of the equation when driving a car. Experiencing the whail of a V10 just cannot be matched by whirring motors and rushing wind.

it has push to pass teehee

That is the sickest looking Porsche in a loooong time!

Well, since the Carrera GT.

or the 2010 Turbo.

That is the system Chevy's Volt, Cadillac's Converj, and Fisker's Karma use. Unfortunately, GM's system is still "wrong." Rather than running at a specifically tuned RPM at all times, offering a good blend of power and efficiency, the gas engine actually generates electrical power on-demand. Which means even though each wheel has its own electric motor, when you nail the throttle, the gas engine revs up just like it would in a normal car. So where the hell is the benefit? At that point, you might as well just get rid of the electric motors altogether.The right way to do it, like you said, is to use a turbodiesel powerplant. Design it to run at <1000rpm constantly. You use the batteries as a power buffer. The engine is always recharging the battery, except under heavy acceleration, during which time the battery capacity takes up duties of delivering "extra" power. You never increase engine RPM because then efficiency starts to drop. You simply take advantage of mixed driving and battery as a combined effort. Battery gets drained (beyond engine charge capacity) during acceleration but gets recharged (beyond power drain from motors) during steady cruise.This design doesn't look good on EPA papers, though, because they will never operate as a ZEV. And everyone knows the EPA is more important than real science. So maybe that's why no one is doing a correct electric-drive hybrid-electric car. No PZEV cert means less tax breaks. I love it when politics get in the way of science.

Because the that's the only way aside from adding boost to get 500 HP from a 3.4L gasoline motor.

0rowing the gears in that thing must be like...i have no f-ing idea ive never had a car that revs that dawm high

Its not really anything that different. Gear spacing will be such that it will feel pretty much like anyother car with a similar amount of power.

yeah i guess just sounds high a** hell just seams like a waste to me
