Sebastian Vettel has named his latest RB6 chassis 'Randy Mandy'.

Giving his cars an amorous female name has become one of the 22-year-old German's several F1-related superstitions.

He religiously steps into his cars and dismounts from the left-hand side, and slides a lucky coin behind the laces of his boot.

Vettel called his original 2010 Red Bull 'Luscious Liz', following on from its 2009 predecessor 'Kate's Dirty Sister'.

But Luscious Liz has been retired after the team found damage in the wake of the Spain/Monaco double-header, dominated emphatically by his teammate Mark Webber.

It emerges that Vettel will now be at the wheel of the fully-updated test car.

It has been a warm and sunny day at Istanbul Park, and more of the same 't-shirt weather' is expected throughout the Turkish GP weekend.
