SPIELBERG, Austria (Reuters) - McLaren's Carlos Sainz and Toro Rosso's Alexander Albon will start Sunday's Austrian Formula One Grand Prix from the back of the grid due to penalties for taking new power unit elements.
Spaniard Sainz will have Renault's latest specification power unit, incurring an automatic grid drop for exceeding his allocation.
McLaren, fourth overall and eight points ahead of engine provider Renault's works team in the standings after eight races, had opted not to make the change and incur penalties in France last weekend.
Stewards said Albon will also start at the back as a result of an engine change.
