SPIELBERG, Austria - The Ferrari Formula 1 team has blamed a wheel nut for Sebastian Vettel missing podium step from the 2015 Austrian GP on Sunday (June 21) and said it must not happen again.
Vettel pitted in the lead, with company chairman Sergio Marchionne watching - after the dominant Mercedes drivers had already stopped and lost an agonising amount of time as the pit crew wrestled with the right rear wheel.
