I keep forgetting to post this video because I always end up leaving it open and listening to the rockin' boppin' mid-'80s soundtrack. Trust me, this could not be more '80s if it was doing lines and tagging a subway train.
The car you're seeing getting tested is the RS200, Ford's Group B rally contender. A little midengined beast, bodied in fiberglass and never quite as successful as the company hoped.
This video was shot in '85, and Group B was shut down just a year later, because it was too fast and too dangerous for its own good.
