The Porsche 917, McLaren MP4/4, Gilles Villeneuve, AJ Foyt and Hans-Joachim Stuck are among the nominees for this year's Motor Sport Hall of Fame awards.
A 15-stong shortlist across five categories – including a new one for racing cars – has been announced, following a poll that attracted more than 40,000 respondents.
The winners will be revealed, and inducted into the Hall of Fame, at the Royal Automobile Club Woodcote Park estate on 4 June. Previous inductees have included Ayrton Senna and Stirling Moss.
Each of the five categories has three nominees, and none is likely to be more closely contested than the new Racing Cars shortlist, which will see the Porsche 917 go up against the McLaren MP4/4 and the Audi Quattro.
The Porsche was near-unbeatable in 1970 and '71, winning at Le Mans both years and taking victory in 14 out of the 17 World Sportscar Championship races in which it was entered. The Quattro, meanwhile, revolutionised rallying when it appeared in 1980 as the first full-time four-wheel drive entrant. Three wins followed in 1981 – including one for Michele Mouton, the first woman ever to win a WRC event.
