Somewhat oddly, BMW chose to accompany the news of their imminent departure from F1 with this video showing their first shakedown test in 1999.
The car was driven at Miramas in France by Jorg Muller, who is now a BMW touring car racer. It was a 1998 Williams chassis fitted with a BMW engine.
The BMW-Williams partnership fizzled out after six years and ten Grand Prix wins. BMW may have beaten Williams to the next Grand Prix win, but Williams are sticking around and haven’t given up yet.
