This is the very definition of a range extended electric vehicle.

Those are not mainstream (the i3 comes the closest). The Volt does NOT fit this... the Volt is a full hybrid electric vehicle. The ICE drives the powertrain at times. It's not simply an electric vehicle that gets additional range from an ICE acting as a generator.

The Volt is a pure EV for 53 miles. When the Volt is in EV mode the engine is never connected to the drive wheels.
The engine provides torque in two of the three range extending modes.

I'm not sure how familiar you are with cars, but the Volt is a hybrid electric vehicle. The fact that it can only run in EV mode for the first 53 miles (just like certain models of the Prius that can run in EV mode for the first 22 miles) and then relies on the engine to assist with the powertrain (i.e. propel the vehicle), makes it a hybrid vehicle. This is different than the BMW i3 which only uses the electric motor to propel the vehicle. The BMW is a true range extended EV.

As soon as you floor a Prius the engine will kick on even with a charged battery. It's always a hybrid.

Green Car Reports titled their article "Chevy Volt - Range Extended Electric Car Ultimate Guide".
I think Green Car Reports knows more than you and they agree with me.
Actually, let's take it a step further. Go here:

https://en.wikipedia.org/wiki/Range_extender_(vehicle)

Anyone can edit it, so go on in there and delete the Volt from this article.
I predict your level of expertise in this area will be challenged very quickly.

These arguments favoring gasoline-hybrids tend to ignore a number of factors: 1) diesel engine vehicles depreciate slower than conventional gas engines or gas-hybrid power plants. 2) diesel engines last longer. 3) if properly maintained, costs for maintenance and repairs are not higher than for gas engines.

So total cost of ownership is very favorable for diesel power plants: depreciation, fuel, maintenance and repairs. Insurance is about the same for each power plant option.

Same kind of goes for hybrids but it really just depends on the price of gasoline. When I bought my hybrid, gas was high and the resale values were out of this world. I was looking at four-year-old cars with 100,000 miles that were selling for about 68% of what I paid brand new, and that's after I waived the $1,500 on the hood for five years at 0%. Those were the needles in the haystack. Now I'd have trouble selling mine for that much and it's 2 1/2 years old with 60,000 miles. Still not terrible depreciation but not that great either.

Maintenance is a bit more complicated. There's the battery issues, but the failure rate on 12-year-old cars is less than 5% so it's pretty unlikely. It's an added expensive. Otherwise there's no real maintenance to the hybrid systems. Similarly, diesels are more expensive. The other issue with cars is there's all the smog garbage I'd worry about. Probably looking at around $2,000-$3,000 based on VW dieselgate and estimates on what it would cost to fix the diesel VWs... the other problem being the reduced performance. Given, that's trying to put a band-aid on a diesel engine that was never intended to be able to pass US smog requirements. I've been in the new 320d BMWs and they're not slouches. Not very exciting but not as slow as you might think a diesel would be.

Prius Electric motor is constantly active regardless of speed, it depends on engine speed. Any Prius owner will see that the minute you let you foot off the gas the electric motor kicks in.

More miles per gallon when driving, diesel doesn't save gas. It's not a gas saving tech. Hybrid saves gas by preventing gas use.

You can go only max gas mileage while continous driving with diesel. It doesn't factor the car on stops and loss of energy on braking. Diesel is no longer viable in the US. Just look at where it is today.

You are obviously not technical enough to know the distinction.
You obviously missed my point when I said a diesel is not for "saving gas," whatever that means, it just gets better mileage on the highway. It can go longer between fill-ups, so effing duh max mileage is with continuous driving. Whilst you're on your Personal attack bullspit, I don't keep up with hybrids, the only one I know that uses it's electric motors at almost any speed is the 918. Diesel wasn't invented for economy, it's just used for it...now. I believe is very well is still viable as a fuel source...if you expand past penny pinching.

The electric motor is most certainly active past 45mph. It continuously aids the ICE while accelerating and charges the battery when decelerating.

Regenerate braking saves the brakepads from wearing down as fast as on traditional cars because regenerative breaking does all the heavy lifting.
Naw, I think I'll do as I see fit. I know/knew how they work ir used to work. Sorry I'm not dying to know how they work and keep up with their technology. If I'm wrong, then I'm wrong. I honestly don't really care for them that much, and the only one I sort of like is the Volt, seeing I drew out the same idea, way back when the Insight was new.

The chevy volt and others fall into this category. A hybrid where the engine is only responsible for charging the battery and not for driving the car. This type of hybrid should give you fantastic range as well as great fuel economy.

There is a clear distinction between this type of hybrid and a toyota prius where the gas engine drives the car.
The Volts engine is connected to a generator that powers the motors and charge batteries, the engine doesn't even need to idle high.
