The Australian Grand Prix will get underway with just 15 cars on the grid after Kevin Magnussen and Daniil Kvyat suffered car failures.
With Valtteri Bottas having already been ruled out of the race after failing fitness tests, the grid was reduced even further when both the McLaren and the Red Bull stopped on the way to the grid in the final half an hour before the start.
Magnussen stopped on the approach to Turn 6 as his engine failed, while Kvyat's RB10 came to a halt with a gearbox problem.
With the grid having already been published - with everyone moving up a spot due to Bottas' absence - Kvyat's spot of P12 will remain vacant while Magnussen had been due to start from last place. Jenson Button is now the last car on the grid in the only remaining MP4-30.
The race will see the lowest number of cars to start a grand prix since the 2005 United States Grand Prix, when just six cars started as a number of teams pulled out due to safety concerns.
