Toyota works to develop advanced electric-car battery
More to compete with Tesla really. I mean Toyota are committed to FCEV over BEV - if only hydrogen didn't cost more to fill up than petrol does on the Prius..

Security Indicator warning light
I have a 2011 Prius bought new. Last night the indicator light began flashing. I don't know what to do about it. My manual does not talk about the light at all. -
Nice KIA Optima PHEV review
Ok,
I am skeptical of non-EPA reports of cars whose existence is documented by press releases and rewrites by automotive press. There are a few exceptions but for the most part, I am skeptical. However, I have grown fond of Robert Llewellyn's efforts over the years and I found something in his latest review:
Apparently Kia is feeding the electric motor power through the transmission. Today's EVs are often single gear-ratio transmissions. At low speed, the torque makes gears redundant but at higher speeds, the back EMF limits the power. If you want high speed, the motor needs to be geared for slow rpm and that is what Kia has done. But how fast do you need to go?
Recently there is a report that the Hyundai Ioniq has set a speed record for hybrids. Piece of cake if you run the motor through a transmission to gear it down.
