The Volt uses a gasoline fueled internal combustine engine after the first 25-50 miles of pure electric drive.

True. I was focused on the word usage & just used the Volt, to illustrate the difference between “engine” and “motor”. The English language has (far) more words than any other language. There are good reasons for having the word “motor”, as well as the word “engine”. A quasi-technical article should get the words right. As Mark Twain said: “The difference between the almost right word & the right word is really a large matter—it's the difference between the lightning bug and the lightning.”
