Wow, I hope they put a description like this onto their web page.

Because when I saw that word "acceleration", the first thing up in my head was a buffed bald man doing a car race with that truck. LOL.

Oh, I watch too many movies.

For quantifying discrete objects, you should use "fewer", not "less". "Less" is used for aggregates, continuous media, and numeric values. So, "fewer people", but "less water".

Thanks for the clarification. However I’m a truck driver, I passed my English requirements for CDl. :)

You needn't do this. Some random bloke thought it'd be a good idea years ago, wrote it down in a book. A certain type of pedant says to themselves, oh somebody wrote it down in a book - that's the rule them. Nope.

You can't use fewer in some places, but the insistence that if you can use it then you must is an zombie rule. If "less" sounds right it's fine.

Thanks for that, but it doesn't sound right.

Also doesn't that torque helps when going uphill?

It definitely sounds like it, considering they advertise the speed on a grade.
