The 29-year-old Scot was appointed as a test driver this year for Williams, the famous British team that is co-owned by her Austrian husband Toto Wolff.

She said her second outing will also be for an aerodynamic test.

"I'm lucky that I'm very good at driving straight," she joked.

Wolff revealed that she expects to enjoy a 'real' circuit test in the 2012 Williams later this year.

"I'm ready and I'm waiting but I think it won't be until October," she said. The regular young drivers' test is scheduled for Abu Dhabi in November.

"I still have some time to prepare my neck," Wolff explained, smiling: "I think in the future I'll have to either wear a scarf all the time or my hair very long, my neck will be so big."
