It's a good question regarding "how long is it 770bhp for". But, I guess like many cars, it doesn't actually need to be that long?

Any car only produces it's peak power in a specific place. Isn't Ferrari's new Enzo gonig to have something similar, but it's all done with the throttle pedal rather than a KERS-type button? So, because you don't actually need that boost throughout the rev range, I wonder if it's ability to produce that power will be ok. Not inifinte, but ok.

You could do the same with cylinder shut off etc., presumably. It's just that the electric motors give the car a headline grabbing 'green supercar' element, which is obviously nonsense. Most cynical supercar perhaps...

So Porsche come up with an awesome looking thing with 770 brake, and you all bh that it might not get 94mpg at all times? Is this Priusheads?

I only get 20mpg to get 412 horse*, a mate gets 17mpg for his 500. If the 918 can get 770hp (even on short bursts) with anything over 15, it's ahead of the curve. 30mpg would have it better economy than a 2.7 boxster (228HP), ffs.

  • average over 10k miles, a run to the evo triangle gives 11....
+1

It's an awesome car with or without the hybrid tech. If Porsche can build a supercar and still bring down the average CO2 of their range then they should be applauded. It's better than building a cygnet clone!

the Author refers to 'GULF' livery several times, am I missing something but I don't seem to recall 'Michael Delaney' driving a matt black and white car around Le Mans?

I, for one, think it's an utterly fantastic car. For the record.

I understood it to be on the combined cycle, and every manufacturer plays around with their cars to try and beat the system because the official combined cycle impacts tax through CO2 emmissions level, initial purchase tax (I think), Benefit in Kind (starts working out man maths to see if I could run one on wifes company biggrin )and Road Fund Licence.

You're actually forgetting this:



Very, very similar to the 918....
But even more efficient. I very much doubt the Porcshe could maintain that 94mpg over a distance due to the fact that once the batteries are dead it's just another V8 Hypercar. The Jag concept involved electric only power and a range extender. Okay, the one in this was a pair of gas turbine engines but Jag have already been testing an XJ with a tiny little Lotus engine being used to generate electricity when the batteries get low. Don't get me wrong, I love the idea of this Porshce. It's one of the few genuinely pretty cars out there and it'll definately be getting a look in in my lottery win garage, I just take the 770bhp and 94mpg figures with a pinch of salt.

Also, it's all great saying that the electric part is zero emmisions, but as the majority of the country still gets it's power from coal and gas, it really isn't.

They really need to do something about the way the combined fuel cycle deals with plug-in hybrids to get rid if ridiculous figures like this.

Nice looking car though.
They allow it to start the test with a fully charged battery. hence the nonsense. That also applies to KERS cars.

Start the test with an empty battery would be better.

Its a short test cycle so any plugging in is bound is skew a drive massively but its relative. Who would use a Plugin but not plug it in?


This car offers supercar performance, a showcase for Porsche Technology and something that can be used to reduce the fleet average CO2 and save an awful lot of money if the EU start fining OEMs for C02 over the limits (120g/km or 130g/km?)

In the US they have 'mpg-e' or 'Miles per gallon gasoline equivalent' which electric vehicles have to have listed.

Not sure how they work it out, however.

The Ford Focus Electric is listed at 105mpge I believe. When you consider what a lot of lower power diesels are listed at and add in the probably worse depreciation from the batteries (or battery rental where you have to), suddenly it doesn't seem quite so amazing.

Think the leaf is listed at 99mpge - when a (very carefully driven no doubt) Citroen AX diesel chas managed 100mpg, it doesn't seem that great considering how much you're paying.

Hmm. I'd like to see the quoted CO2 output on this thing.

There's likely to be a big financial incentive for people to buy these new supercar hybrids. Many of the customers will be *actual* company directors, as opposed to the powerfully built sort we have on this site. hehe The tax bills will be slashed for low CO2 cars compared to, say, a Ferrari 458, and the driver still gets a 770bhp motor with posing ability.

Even if it is a giant tax dodge, I still think it looks great. biggrin

The problem there is that battery packs don't like being entirely discharged, plus the fuel burning part of the system would have to simulataneously recharge and drive the car - higher fuel use than a non-hybrid version of the same thing.

We need a new test, even for simple petrol engined cars the test is confusing to the average driver, who seems to think it should predict the MPG he gets when he drives to work without the slightest attempt not to burn lots of fuel.

This is great- everyone should stop moaning!

Sorry if I've latched on a previous post that people don't care about, but cars like this are absolutely required to move technology on. Yes, battery technology is due for a big change but you need stuff like this to get people interested & talking about it before industry starts to invest the billions that are needed to make the next step. Apart from anything else, I'm sure you'll find the battery can be replaced with a similarly-packaged item when new technooogy comes along. And the existing one can always be recycled e.g. mobility scooters & Segways!

How could you fall from the heights of the Carrera gt to this poop ? 90 bleeding mph , who gives a god damn ? You've just spent almost a million euros do they think a few mpg is going to kill the deal ? Who wants a hybrid Supercar ?
Short sighted madness .

I knew it would be crap when they showed me the cruise control .

No thanks , I'll get an f40 and a 959 and spend the change in stringies .

Only 770BHP?! It's 160BHP more than a CGT FFS. And where did you get 1700kg from?

I think the black and white colour scheme hides the lines of the car. Think it's stunning in a solid colour. There is a lot of awesome in this car and it's design.

Also, I recently found out Porsche bought/use the KERS design off the Williams F1 team.

6% BIK is still ALOT of money on a £600k hypercar... there is no tax dodge really.

Point taken. But it's less than 35% which a non-hybrid supercar would get you.
