Dirty diesel versus pure electric.

Or Audi SQ7 versus Tesla Model X 100D.

This is not the performance version of the Model X, so it's not necessarily a given that the electric SUV will come out on top.

Video description:

"Imagine you have around £100,000 to spend on an SUV and six friends to carry. The thing is, you're always in a massive hurry, so you absolutely must own the quickest car for the job. To answer this most first-world of problems, I pitch the diesel-powered Audi SQ7 - complete with magnificent 4.0-litre V8 - against the Tesla Model X 100D to find out which is fastest."

"In the last of my internal combustion vs battery power face-offs, the Tesla Model S managed to edge out the Nissan GT-R. So can the pride of fossil fuels really rely on a diesel SUV? Find out as I put the pair through their paces."

Even this lesser version of the Model X proves its might though. And it even wins in some other less-expected tests.
