Ferrari boss worried about Vettel's gearbox

Ferrari boss Maurizio Arrivabene left Russia concerned that Sebastian Vettel's crashes with Daniil Kvyat might have caused damage to the gearbox.

According to Speed Week, an investigation showed that there was damage, and so a new gearbox will be installed for the Spanish Grand Prix in Barcelona. The German driver will not suffer a penalty.

As for the current Mercedes versus Ferrari pecking order, Toto Wolff warned that not too much should be read into Sochi.

"Our conclusion is that, if our lead was bigger at Sochi, then primarily it was due to the circuit characteristics," said the Mercedes team boss.
