Wow, it takes two hours to charge to then go 15 EV miles?
Working backwards from Specifications it appears to have a 10 gal. tank for gasoline

Why is the AER zero? I thought the i8 could go a few miles in pure electric mode.
Regardless, those EPA in numbers are pathetic. The i8 is all about form over function.

The Chevy Volt EPA sticker shows 38 miles all electric range(AER)
The BMW i8 EPA sticker shows no AER. 15 miles electricity+gasoline and the rest gasoline only.
What the MPG is on sports cars like the i8 is really hard to determine.
The reason is the regenerative breaking. The Porshe 918 is a hybrid that never has to be charged, the massive breaking on a sports car recharches the car. In the interview the porsche guy says the electric engine never needs to be charged. The breaking alone will provide so much power to the EV engine that it is enough to keep it ful non-stop.
I found this fact extremely interesting.
The i8 needs to be recharged, but it will recharge a lot if you do a lot of breaking.

The i8 is a light carbon sports cars, the tesla is a family sedan at about twice the weight but much more functionality, it's comparing apples and oranges.
Which car you prefer depends entirely on what you're looking for in a car, the i8 isn't a car to take the kids to school, the Tesla isn't a car to take on a track.
Depends on what you want.

I'm not even going to give you "in it's price bracket." The i8 is a nonsensical set of compromises. It makes no sense at all to me. I wouldn't pay 40K for one. Why? What does it do that a conventional car doesn't, other than have sweet almost-Lambo doors and gee-whiz look at me styling? Honestly, I'd rather have a used Boxster. At least the top goes doesn't and you can shift it yourself.
I'm retaining a bit of an open mind--if and when I see someone really wring it out on a track AND demonstrate that it's performance remains consistent for more than a lap or two, I will retract some (though certainly not all) of my criticism.
I'll give you that the low weight is impressive. It would be even more impressive without the battery and electric motor. Put a decent ICE in the back and maybe it'd be a neat car.
As it is, it's like a screen-doored submarine. Jack of no trades, master of nothing.

Ex got M3 in the divorce, waiting for EU Model Y!
As I said earlier in this thread the i3's lightness paired with the amazing 1.5 litre 3 cylinder ICE are the things that stand out.

Perhaps this was posted up thread? In any event, the powertrain sounds intriguing, but I stand by what I said before--for my money, the 911 is the much more convincing sports car. And if the i8 isn't a sports car, what is it?
Edit: note the car being compared here is the base 3.4 911, not the S (which is a little bit closer in price).

And I would also be curious on how the i8 performs after the first couple miles of track time. Just based on the electric-assist range, seems that it would run out of e-assist in <5 miles of track driving -- assuming there's no thermal or battery discharge C-rate limiting before then.

Anyone know the highway number for the i8?

One answer could be that it doesn't matter, because current "supercar" (I am not sure which cars that term includes) buyers don't buy based on fuel efficiency.
But another answer could be that is only because no current offering is efficient; perhaps more people will buy more efficient models. For example, I never in a million years would have bought a Porsche 911 cabrio, even though I always wanted a car like that - I just couldn't justify the fuel use. I did buy a Tesla Roadster. I don't care how it performs on the track because I don't drive it there.
Of course now that I have a Roadster, the i8 is not efficient enough for me. But there may well be people out there that think it is. There doesn't have to be a lot of them, because the i8 is a halo car that is more about bringing people in to the showrooms rather than selling in quantity. And, hey, I probably will stop by a showroom to see it...
