1985 Austrian Grand Prix

Prost took his fourth victory of the season by 30 seconds from Brazilian Ayrton Senna in a Lotus-Renault, with Italian Michele Alboreto third in a Ferrari.

This was the last F1 race until the start of 1987 in which a car with a naturally aspirated engine was entered, Martin Brundle failing to qualify his Cosworth-powered Tyrrell.

Before Saturday morning practice triple and defending World Champion (and 1984 Austrian Grand Prix winner) Niki Lauda, flanked by a very unhappy McLaren team boss Ron Dennis, announced to the media that he would be retiring for good from Formula One following the season ending Australian Grand Prix to concentrate on running his airline Lauda Air.

Elio de Angelis' Lotus dived left to avoid Fabi and was hit by the Ferrari of Michele Alboreto.

On lap 13 Andrea de Cesaris survived one of the biggest and most spectacular crashes ever seen in Formula One when his Ligier-Renault went off-line at the left hand Panorama Curve and slid onto the outside grassy embankment at high speed.

The grass, wet from overnight rain caused the Ligier to initially slide sideways before his right rear hit a slight bank launching the car into a series of 4 consecutive mid-air rolls and flips with de Cesaris's head bouncing around freely in the cockpit.
