The trigger for the multi-car pile-up was an oil spill on the approach to the Klosterthal curve, near the Steilstrecke section. The first car to hit the barriers was the #503 BMW 330i, which crashed head on into the tire barrier.
Miettinen, following closely in his BMW 325i, spun on the same spill. His car slid sideways and struck the rear of the stationary 330i at a 90-degree angle, driver side first.
These T-bone collisions remain among the most dangerous scenarios in modern motorsport, reminiscent of the fatal accidents of
Anthoine Hubert and Dilano van’t Hoff.
