Spielberg, Austria: Russian Daniil Kvyat will start Sunday's Austrian Grand Prix from the pit-lane in a new Toro Rosso chassis following his rear suspension failure during qualifying on Saturday.
The former Red Bull driver, whose car was damaged badly after he ran across the controversial new kerbs at the Red Bull Ring circuit and then smashed into the barriers, was unhurt.
He will have an advantage in being able to set his car up for the cooler conditions, with rain forecast, that on Sunday replaced the hot weather in the Styrian Alps on Saturday.
Race organisers overnight rejected a plea from Mercedes boss Toto Wolff to revise the kerbs, suggesting instead that drivers should keep off them.
Several drivers experienced problems with the kerbs, particularly the new yellow 'baguette' kerbs, and three - championship leader German Nico Rosberg of Mercedes, Mexican Sergio Perez of Force India and Kvyat - suffered suspension failures.
Defending three-time world champion Briton Lewis Hamilton, who took pole position for Mercedes, also suggested a re-think was needed "before somebody gets hurt".
After a track inspection late Saturday, however, race director Charlie Whiting said there was no need to change the kerbs.
The change of weather on Sunday may favour Hamilton who starts the race on ultra-soft tyres, which have lacked durability in hot conditions. He and Rosberg suffered blistering on their tyres on Saturday.
