Nissan Wins Environmental Award for its e-POWER technology (REx BEV)
7 replies, posted
Nissan won a renowned environmental award in Japan for its e-Power electric powertrain technology on the basis of its contributions to the reduction of carbondioxide emissions. The e-Power electric powertrain technology played a key role in making the Nissan Note the most popular compact car in Japan in 2017.

The Nissan Note e-POWER is powered by an electric motor that is powered by a gasoline engine. The electric motor drive system is 100 per cent electric and provides motorists with the benefits of quiet operation, powerful acceleration, and high fuel efficiency. The gasoline engine is used exclusively for generating electric power. Hence, the engine always operates at its optimum condition and the Note e-POWER demonstrates 30 per cent more fuel efficiency when compared with cars which are powered by conventional petrol engines having similar output. The Note e-POWER has a fuel economy rating of 34.0km/L which exceeds 2015 fuel economy standards in Japan by 97 per cent.

EU debut later this year apparently.
I would absolutely buy one of those. Don’t get me wrong, I love my twin turbo Audi wagon, but 22MPG on premium makes you REALLY appreciate fuel efficient cars.
Good on them, they deserve the award. 80MPG is phenomenal.
You know what sucks? I'm incredibly happy about the news and very impressed. Yet, I'm having a hard time thinking of myself driving a hybrid or full EV car. I have an itty bitty Chevy Sonic LT and I enjoy driving it because it doesn't sound awful like most i4s and has semi-manual transmission and it is the best feeling car I've ever owned. I'm fully aware ICEs are inefficent and pollute but...I can't see myself not driving one because it's kind of the only enjoyment I get out of life right now, even if it's a rather low performance car. (Frankly, it's probably best I don't get a high performance car, I'd be unable to resist driving like a maniac)
However, I wouldn't complain if I was a passenger in an EV/hybrid. So maybe self driving cars will help me help the environment because I don't need the fun factor as a passenger.
Wait I'm dumb how did they get petrol->generator->motor to be more efficient than petrol->motor
EVs are extremely efficient, engines aren't. But when you can run the engine at it's optimal rev range constantly then they are a lot better. Plus you get regen braking. Diesel trains work this way as well.
The engine runs at a constant speed to generate electricity, always having the optimal load. The electric motors are absurdly more powerful at every speed than an engine. And the engine doesn't have to be always running, either. And since the engine is only generating electricity, it doesn't have to be big.
For example, freight trains use electric motors, the giant engine is a generator for those lucriously powerful electrical motors.
I love ICE-electric powertrains. Such a smart way to bridge the gap while battery technology fully matures. Locomotives that use it are far and away more efficient and comfortable than simple diesels - the regional line in my area has just recieved DEMU's to operate on the non-electric part of our network, replacing Intercity 125s, and I think that's brilliant. Should have been done long ago.
The petrol engine is running at its optimal range, so you are not using more gas than you should, the electric power train has an easier time putting out torque to get the car moving, etc.
also iirc petrol powertrains have very low efficiency.
