Watch Jay Leno driving an incredible 1911 firetruck through the streets of LA

US-based talk show host and car collector Jay Leno has a vast and varied collection of rare and interesting vehicles – and what's best is he keeps as many of them as possible in usable and roadworthy condition.

This week, Leno decided to give one of his most unusual vehicles an airing. It's a 1911 Christie fire truck, one of the first ever deployed, and it's little short of majestic. It's powered by a 20-litre (that's right... 20 litre) four-cylinder engine which powers the front wheels in an unusual arrangement. At the rear sits a massive pumping machine, which would have been horse-drawn before the remainder of the Christie system was bolted on.
