Formula 1: Pastor Maldonado's Williams had a piston failure at Sepang says Renault

Rémi Taffin, head of Renault Sport F1 track operations said in an interview, "We used the intervening time between Malaysia and China to thoroughly investigate the engine failure we had on Pastor's car in Malaysia and quickly identified it as a piston failure. As a result we are looking to put in place safeguards to prevent it happening again to Williams or our other clients."
