The Ford Sierra and its Escort successor aren’t exactly the best-remembered cars for road driving, judging by the glowing reception of the Ford Focus that took over their job. But enthusiasts still adore them, and they have the Cosworth versions to thank.

What you’re watching here is just a testing video for the Sierra RS Cosworth, the Group A race car that competed both in touring car racing and in full-on stage rally. It ended up giving its guts to the later Escort RS Cosworth, currently enjoying full-on Gymkhana treatment.

At the wheel is Ari Vatanen, the legendary champion who wrangled the then-ancient MK2 Ford Escort to a driver’s title in 1981 as a privateer. The man could wheel, as you’d know by reputation. And you’d know that from watching him get so much speed out of this 1987 Sierra. He’s off the ground as much as he is on, shooting fire as he goes.
