Both Cadillac drivers forced to retire from Austrian Grand Prix just five laps in

Disaster struck for Cadillac in the Austrian Grand Prix as they had one of the worst starts to a race in recent history.

An electric start at the Red Bull Ring saw F1 leader Kimi Antonelli avoid a punishment for going off the track while Lewis Hamilton pushed his former teammate George Russell hard in the opening laps.

But it was a nightmare start for Cadillac as both of their drivers were forced to retire a mere five laps in.

Valtteri Bottas came into the pits early on and complained that his brakes were on fire. It followed a similar incident in practice and let to an early withdrawal.

Liam Lawson of Racing Bulls also said "I've got my car on fire" on team radio but then it was Bottas' teammate Sergio Perez who headed into the pits with a carbon-copy situation.

Perez told his teammate that he had "a lot of smoke in the cockpit" and he too had to exit the race prematurely.

According to journalist Chris Medland, Cadillac said that brakes on both cars were overheating as a result of the high temperatures.
