• BMW considered V10 and V8 motors for the i8 - Cooling problems killed it

      The BMW i8 is a gorgeous car. Finally a high end BMW with looks to rival sports cars from competitors and with a $135,925 point of entry it is placed in some elite company. The only problem with the car is that at that lofty price point just about everything else in the range is far more powerful. A report from a Dutch publication states that BMW originally considered a V10 or a V8 for the i8 which makes far more sense for a sports car in this price range.

      What killed the V10 or V8 off? The hybrid drivetrain. Once the decision was made that the i8 would be the halo car for the 'i' brand a premium was put on the electric efficiency aspects. The batteries and electric motors generate heat and so does a high horsepower V8 or V10. One would think BMW engineers would be able to resolve those issues but they decided instead to pair a 1.5 liter turbo direct injected three-cylinder to the electric drivetrain. Would the more powerful 2.0 liter four-cylinder N20 engine generate much more heat than the 1.5 liter turbo motor though?

      Someone at BMW perhaps should have considered the car might make far more sense without the electric drivetrain. This is not a high volume model that will revolutionize transportation worldwide but a statement vehicle for BMW. The car is to show off as they do not include those doors because they are cheaper to manufacture.

      The problem is since this car is partially designed to get attention for the BMW 'i' brand it really is the 'i' brand that killed any chance of a V10 or V8 in this sports car. What about a simple resolution? An i8 M? Well, BMW is saying no to that for now. The thought that BMW considered a V10 version though and opted against it definitely hurts enthusiast appeal. An S85 V10 under the hood with 500+ horsepower in an even lighter car without the electric batteries and motors? That would have been special. It would have been a proper M1 homage. And That is what we should have. That is what we still could have.

        If they want an icon it should perform like one.
        I agree with you, but reallistically I don't think an N20 will come close to the low mileage goals BMW set for this car.
        The performance is always designed to first come from the electric engines.
        Mind you, The 3-cylinder as tuned for the i8 is still pushing 231 hp/320 Nm which gives a combined torque of 570Nm, and a 0-62 of 4,5 seconds.
        Not at all what the package suggests, but not too dramatic.
        It's just not supercar performance. It wil keep up with a FBO 135 though Click here to enlarge

        So the goal is a $130k Prius?

        I mean either build a sports car or don't. Do not go in-between and then make excuses. But whatever...

        Basically, yes, I guess.
        BMW really wants to promote their "i" brand.
        The built an i8 with a 6-cylinder engine and found out it ran too hot.
        Apparently they were not prepared to:
        1. change the looks of the car
        2. drop the electrical engine and batteries

        In the end it's their decision.
        Let's see who is gonna buy this car other then feel-good moviestars who will be delighted to actually ditch their Prius.

        You want to know who will buy this car? The most pretentious douchebags on the planet. "Oh look at my new $130k BMW but I'm also saving the planet hrrpy derp come smell my farts."

        I can't wait until I waste one of these on the street hopefully with some nice flames shooting out my exhaust pipe which will light the i8 owners own farts.
