Yes it is, but it defeats the purpose. One HP takes 745 watts to produce. X1000 and you have 74.5 kW (at 100% eff. which is not possible). The batteries will be so big there will be no room for the passengers. Or, you will only make very short, fast, fun trips. I thought we were after efficiency?

It's supposed to reduce car weight by like 500kg over all the components, which would increase range. Its also supposed to improve regenerative breaking.

You're also not also going to always be using all 1k of those hp, unless you keep it floored all the time.

I think 1k hp is initial output, like 4-500 hp when cruising.

It would be a huge step forward, but 500 kg?? That's 1100 lbs. A big block V8 doesn't weigh that much. Color me skeptical. Also, regenerative breaking is way over hyped. At 100% it can only recover your deacceleration energy from the time you brake to when you stop. Maybe 6 or 7 seconds worth?

It never hurts to be skeptical, that's just what they said it would reduce the weight across all the components of the ev that will bea redesigned for the axial flux motor.

I get a few percent kicked back by regenerative braking. It's a convenient range boost, but the real nice thing is that I almost never need regular brakes to stop. That'll save a few bucks in maintenance down the road.

One interesting thing is that due to the speed of the tech changes in the EV industry is that the cars are becoming more like computers. They are obsolete when they roll off the lot.

Merry Christmas All!

You aren't wrong, but that is true of all new cars, not just EVs. The new gadgetry in terms of GPS, music, and other displays, is in all cars, and the stuff in line is already two years ahead of what's on the lot.

EV battery technology is not advancing as fast as I had hoped, in terms of range in particular. Most cross-over SUVs are at about 320 miles, give or take, on a full charge, and thought that is far more than necessary for every day driving, its going to take battery tech to get you close to 500 I think before the confidence scales tip in their direction.

My unrealistic expectations about improving range caused me first to lease a Model Y, now I have a Cadillac Optiq. Same range, effectively, three years apart. That just isn't going to get them over the hump, imo.

That and charging networks seem stalled in terms of expansion. That also needs to be improved.

Ford Motor Company has lost $30 Billion over a handful of years betting
that consumers would want electric vehicles. They believed the big lie
that was coming from politicians. I don't know of anyone who wanted one.
The rest of the article is to be read behind a paywall.
