Takao Asami, Nissan senior vice president for research and advanced engineering, says the company's upcoming electric all-wheel-drive system will be "a true breakthrough" and will allow the automaker's future EVs to match sports cars when combined with its latest chassis tech.
Nissan making possible decent cars again? Color me surprised.

Just break away from the French enough to use their money and get back on top.
"Twin-motor" you mean. No engines on a Leaf.

semantics at this point
NickD said:"Twin-motor" you mean. No engines on a Leaf.
I think you might be making up definitions. Go look up engine.
Im interested.

A motor is defined as converting any type of energy to work (so, in this case, electrical energy to work, making it an electric motor). An engine is defined as converting only thermal energy to work. So, all engines are motors, but not all motors are engines, and in the case of an electric car, they are not engines. Hence why the big dog Tesla 3 is a Tesla 3 Dual Motor.
In reply to NickD :
Oxford says "a machine with moving parts that converts power into motion" - nothing about thermal energy. Just power. Electricity is power just as combustion is power.
Webster says "a machine for converting any of various forms of energy into mechanical force and motion." Again nothing about thermal energy.
In reply to dculberson :
I' don't think I've ever heard anybody talk about Electrical Engines or an AC Engine or a DC Engine though.
Sure but that's because motor flows better when spoken or written not because engine is exclusively thermal power
If you're going to stick to common terminology for the sale of clarity, "twin engine" has pretty much always referred to ICE cars while EVs always use the term "motor". A headline about a twin engine Nissan is going to raise very different expectations than one about twin motors. I know I was a lot more excited at first.
I'm with Nick on the definitions. All engines are motors, but not all motors are engines. Oxford seems to be at odds with some of the other dictionaries.
If I can't have my Oxford comma, I at least want this Leaf.
Geez, calm down and talk about the car instead of arguing semantics.

What about a Difference Engine?

NOT HELPING
;)
If you consider an "engine" to be an engineered device with a bunch of moving parts and mechanism and stuff, like the "difference engine" or a "train engine", I wonder if somebody would be crazy enough to make an electric "engine" with pistons on connecting rods, and the pistons are moved by powerful electromagnets, switched by points on a camshaft...
That sounds wonderfully Goldbergian.
If it's switched by points, how do you control engine speed?
I'd like to think that's something that comes to the mind of the builder the first time he connects the battery...

Ya nailed it stu. Quoted for the oblivious.
I love an opportunity to revisit that XKCD, but I'm not clear when anyone was not "calm." People seem to very readily confuse discussion with arguing.
@Keith: I'd love to see a dictionary that defines it that way, honestly. I see the "engine = gas" thing every now and then but only in a "because I think so" sense. I think it's like "sports car = convertible" - a common belief that's not really true.
@Knurled: Or "siege engine."
Don't see too much gas being burned in that thing. Lots of ass being kicked, though.
Seems to me Motor is derived from Motivate or Move, Let's Motor to Moms in the Motor City in our MotorHome.
Engines can do things other than Move, like Convert Dollars to Yen, Encrypt Messages, Convert Energy, etc, so an Electric Motor in a washing machine isn't really motoring is it? It is an Electric Cleaning Engine. LOL The English Language sucks, Mahalo nui loa
Oh I forget to mention, i think it is Volvo that calls their Hybrid "Twin Engine", with both a gas engine and an electric motor.
I ran across this when researching cars that couple two engine together.
I'll use motor if it's electric and engine if it's ICE.
I might be wrong to do that but I don't care. I also drive 70mph in a 65 zone, sue me.
I've always wondered why the marketers don't use the "traction motor" name. Makes it sound like your EV will blast through the winter!
Seriously though, my neighbor got a new leaf and it's fine. Certainly the only Nissan product I'd even consider buying new.
The press release of how the dual motor system works reminds me of how Mazda described its G Vectoring Control system.
From Nissan:
By controlling the two electric motors delicately, the vehicle is controlled to prevent it from swinging. For example, when decelerating in urban areas, in addition to the normal front motor regenerative brake, the rear motor regenerative brake is also used to suppress changes in the posture of the vehicle body and reduce occupant swaying in the longitudinal direction. By reducing the back and forth shaking, the effect of suppressing car sickness is expected. In addition, when accelerating or passing on uneven road surfaces, the motor is optimally controlled to reduce changes in body posture and provide a comfortable ride.
Color me interested if this comes to fruition.

Condensed: "it has regen braking at both ends like any other all wheel drive car"
