So it actually work as a sports car?
For the most part, like a charm. In sports mode, using the paddle shifters, it disguises its hybridness entirely. It'll leap ahead with lag that's barely perceptible. Honestly it does an amazing impression of a 340bhp big six, rather than a 231bhp little triple. In sport mode some of the engine's natural frequencies are amplified through the hi-fi, and it's a strong, gutteral sound. The real pity is it doesn't rev beyond 6500, and for some reason its shifts up by itself on the red-line, even if you're in manual mode.
Even when the battery is pretty much depleted, by the way, you still get all the power of petrol plus electric. Remember, you never drive any car flat-out all the time, and so in the i8 (and any other hybrid), when all the engine's power isn't needed, spare is syphoned off to charge the battery just enough that for the next squirt of acceleration you can have the full petrol-plus-electric beans.
Is it 911 fast? Doesn't feel quite at that level. You don't get the high-rev drama or violence. But it's ruddy quick, be in no doubt. I believe the 4.4sec 0-62mph claim, because traction's so good.
So was this re-invention of the car worthwhile?
Well, it costs £95k after the Government grant, and a 350bhp 911 Carrera 4 PDK is £80k if vastly more tax-heavy. Now, was it worth all this BMW brainpower and new tech to make a car slightly less sporty than the Porsche that uses rather less fuel? That's a very dull question. For a start the 911 is 50 years into its development; the i8 is a first stab. I suspect different tyres and a firmware flash will soon improve it. But more than that, the i8 is exploring the future. It bestows lightweight construction, hybrid expertise, and a quick-thinking highly creative engineering mentality onto the whole BMW group.
It's an enormously satisfying thing to drive, because if you're thinking about it you can use its different characteristics in different ways to suit the moment - in fact it's at its very best either wafting in pure-EV mode, or being thrashed in sport mode.
And it makes everyone point and smile.
