Re: Predicting Range & Value of LEAF Gen 2

The Hyundai Ioniq achieves a 124 mile range with a 28 KWhr battery. Assuming Nissan has learned something about aerodynamics and efficiency in the last 6 years, this could equate to 177 miles of range with a 40KWhr battery. If Nissan gets this kind of range out of a 40KWhr battery and keeps the Leaf price around $25 it would be an absolute game changer.

Yes, lower aerodynamic drag, and better drivetrain efficiency get more range out of any given battery pack.

Another article up at PushEvs predicting a 38.1 kWh battery but also a 160mi range. He is also predicting the closure of the TN and Japanese battery factories but that seems very thinly sourced.

Nissan released a new teaser touting aero improvements. I like that their solution to range isn't just brute-force adding more batteries. This should hopefully keep the price of the car down.

I agree. The efficiency of the current model drops like a rock at 55mph and above (just based on my experience). If they can shift this efficiency drop to 65mph it would make a big difference in the overall utility of the car.

I agree.

Also lol at your username!

The chemistry needs to be improved so cooling isn't needed. Once the cooling crutch is used it's hard to get off of.

I applaud Nissan for making the right, but difficult choice.

If you're in a climate that the Leaf doesn't work as well in, by all means buy a Garbage Motors Bolt.
So in your opinion the right choice for nissan is to treat the battery now as if it's a battery from the future; give or not give active cooling based not on the current chemistry actually in the car, but the chemistry that they have in a power point presentation of their hoped-but-currently-unavailable state?

Highly doubt that is his opinion more than it is yours.

It is correct to state that using TMS is a bandaid solution because it is. Even Musk admits that. The reality is TMS would add to the price. I choose to not pay that price. It is a personal decision we must all make.

Except, as I've pointed out, Volts have a TMS and they are quite reasonably priced. Sacrificing the longevity of your vehicle for a short term, and TINY, difference in price is myopic.

Hopefully Nissan has learned their lesson and won't repeat that mistake. Has it been determined whether latest chemistry still suffers from significant degradation in heat?
