@roger I agree! A 50-100 mile EV with a 50 hp range extender / backup generator is my preferred configuration.

@sd "@charlesH. I have never driven more than about 150 miles and I have never charged using DC fast charging" "so you would spend at least 2 hours" Yes, EV s work best for local miles. ICE work best for road trips. A PHEV puts both technologies in the same car. That's why many of us like them best. ( And they're currently cheaper.)

@sd How much time do you spend charging on a 600 mile road trip with your Bolt?

I'm a PHEV fanboy. I currently drive a kia Niro PHEV. 80% of my miles are EV. NIRO is 26 mile range, 60 HP motor, 100 HP ICE. My ideal PHEV would be 50 mile range, 200 HP motor, 60 HP ICE.

A step in the right direction, but the use of sodium as the coolant is risky. There are better alternatives.

ID4gtx AWD 0-100km 6.2s 10-80% recharge ~40min Ionic 5 AWD 0-100km 5.2s 10-80% recharge ~20min

PHEV. The best of both worlds for me. Cheaper thanEV. Home/solar charging for local miles. Gas infrastructure for road trips.

flywheel charges at 5kw from grid over 10hr and discharges to EV at 150kw for 20 min.

KIA Niro PHEV is my current car. Hyundai Tucson PHEV is probably my next car. I'm a PHEV fanboy. It allows me to utilize gas or electricity with ever is cheaper and/or more convenient.

Half the country (mostly Democrats) thinks global warming is a serious threat but only 2% of consumers buy electric vehicles. Pass the popcorn?

that's expensive. I pay 0.035/kwh off peak at home to charge my PHEV.

1000 free miles.

rav4 prime does have a heat pump.

costs $1B returns $3M/yr? Taxpayer ROI 3/1000 / yr = 0.3% / yr ? Am I missing something?

I have a Niro PHEV and like it very much. About 50% of my miles are now EV. Cross country fill-ups take 5min (vs 50min) and $10,000 cheaper. Any bets as to when BEVs reach 50% market share? Now <2%? Wake me up when it reaches 10%.

"If you're going to go PHEV, today's batteries are more than adequate (they were adequate 5 years ago). Getting 2/3 of energy from the grid and 1/3 from a liquid fuel supply should be good enough." I agree with this. Most richer people who buy EVs (to virtue signal) also have a gas SUV. The PHEV configuration combines both functions in one car, at a much lower price point. I just purchased Kia Niro PHEV. My driving is bi-modal, local miles electric and long trips gas.

This car is on my short list (the other being the Hyundai Kona). I was hoping the Niro PHEV would have the e4WD option developed by Hyundai Wia as rumored. Now I have to decide between highest mpg (Niro) and 4WD capability (Kona. I live in snow country).

Tesla used 7 cents/kwh in their ev ($1.26/mi) vs diesel ($1.51/mi) operating costs comparison. Where do they expect truck drivers to be able to purchase electricity on demand for 7 cents/kwh? Certainly not in California! I suspect the ev operating cost advantage disappears if they assume California rates (15-30 cents/kwh).

Looks very promising. I'm holding off buying a new car to see if I can get this engine. Hopefully in a year or two.

My take. New OPGCI engines will extent the life of the ICE for decades to come. HEV/PHEV will achieve large penetration but EV will be very slow to gain acceptance until battery cost and charge time improves significantly.

"The development of an engine for a light-duty truck demonstration vehicle, which will surpass the United States 2025 Corporate Average Fuel Economy (CAFE) targets. The vehicle will debut at the 2018 North American International Auto Show, in Detroit." WOW! That's next January. I had been planning to buy a atchisen cycle plug in hybrid (Niro) next Jan. Now I'm going to wait and evaluate if I should wait for a OPGCI based plug in.
