Whether you like 'em or not....they are definitely a wave of the future.
Not sure what I think about the whole idea myself. Still have the rear luggage boot which is nice. It's pretty slick the bolt in rear cradle that holds some of the batteries, Tesla motor, cooling, etc. The "custom" look is pretty bad as to me. https://www.youtube.com/watch?v=hJTNsH-SIqk |

Batteries will get lighter.
And you can put the electric on the transmission. It doesn't help with range but I would definitely do it for fun. |

Batteries will get lighter. Keep drinking the Kool-Aid. (IMG:style_emoticons/default/lol-2.gif) The promised land of battery technology is always 10 years away . . . as it has been for the last 20 year or more. It's always a trade off between range and weight. |

It's always a trade off between range and weight. What the heck are you talking about (IMG:style_emoticons/default/confused24.gif) Sure it's a compromise between range and weight, but the range batteries get for the same volume/weight today is many times more than just a decade ago. Maybe the weight of the battery hasn't changed so much, but the amount of juice inside it certainly has. Remember that 30 years ago these cars would have been crammed full of lead acid batteries that just "might" get you to the grocery store and back.

Point being Lithium is the lightest metal (and 3rd lightest element) so not likely to find a new metal to replace it anytime “soon”. Yes, battery energy density is increasing but it is still a long way from the energy density of gasoline. Always fun to (IMG:style_emoticons/default/stirthepot.gif) on the EV topic (IMG:style_emoticons/default/happy11.gif) My end point being that the weight of the batteries is what destroys the handling - especially with a 914 conversion. That’s OK if you only drive in a straight line to go get ice cream as your fun drive. I prefer something that handles better than that. |

My end point being that the weight of the batteries is what destroys the handling - especially with a 914 conversion. That’s OK if you only drive in a straight line to go get ice cream as your fun drive. I prefer something that handles better than that. Well, let's consider these two examples. They said the rear battery pack plus Tesla drive train weighs about the same as a Six engine and trans. Okay, I've heard people argue even the extra weight of a six takes away some of the nimbleness of a four, but people seem to be pretty happy with the handling of their sixes. Let's just consider that if they dropped the front battery pack, the weight has been held about the same. It's hard to know how the distribution of weight between battery pack and motors affects moment of inertia compared with a stock ICE. It looks like maybe it would be moved toward the axles a bit more, but seems it would be close(ish). Seems like you should be allowed at least a small battery pack in the fuel tank compartment to make up the weight of a full tank. Overall, some range would be lost but how much? The point being that even with current tech, you should be able to EV a 914 without destroying the handling if that were the priority. It's all good because I know that you secretly fantasize about your own 914 EV (IMG:style_emoticons/default/lol-2.gif) |
