- bmw i8 Electric Vehicles
Well, it is not really an electric car - is it?
Having said that, what an odd design decision on the part of the i8 engineers - to have just a tiny trunk in the back with the ICE (where anything you haul gets extra hot), yet not offer a frunk. Judging by those pictures, there would seem to have been some opportunity for a frunk space-wise, but it went unused for whatever reason?
BullS**t. I see at least 3 fluid reservoirs and the 12v battery under that hood. That's plenty reason.
The BMW technician (who is training BMW dealership folks) says on the video that the i8 gas tank can sometimes take 1-1.5 minutes to open due to pressurization.
Water can be filled up without opening the front. You don't need to open that.
Furthermore: That pressurization issue only applies with the tank being completely empty.
Not a top speed issue (at least for me), it's a range issue. The amount of energy used at Autobahn speeds is enormous so the recharge frequency is the problem from my perspective.

@Realist: I'm very interested to know, if you have experience enough yet to answer, how much range you get at your typical high autobahn speed with at fully charged and fully fueled i8???
According to bmw.com there is an optional equipment 'Large fuel tank', did you get that? I was unable to find a definitive answer to the tank size, one site said "10.5-gallon" tank but didn't specify if it was US or Imperial gallons and, as I mentioned, it seems there are two tank sizes available as options?

I'll reserve judgement until I see evidence for that. Aerodynamic impact on range increases geometrically with speed.

with what, a radio controlled airplane? Passenger cars take at least 20l/100km @200kph

That is simply amazing! It would suggest an extremely high efficiency of the engine/drivetrain and/or extremely good aerodynamics. I'll do some calculations when I get home but... Wow... Are you sure though that the numbers are correct?
The main difference is the electric motor still assisting at that speed with its 2-speed gearbox. Therefore it's always in its optimal efficiency band. Furthermore I have the small ultra low resistance tires.
There is of course a big difference between cruising at 200 and going full throttle. But the car will stop you at 250 anyway. Without the limiter 270 should be possible.

Do you have full acceleration and top speed the entire 400km? I'm still surprised you bought this car. You've gone on and on for over a year about the drawbacks of the Model S on the autobahn and how expensive it is. And how it can't be taken to the track at full speed. You bought a car that costs as much as a Supercar but even you said doesn't perform like one. It is a cool looking car so I guess that was your primary consideration.
