Contary to reports, Sebastien Buemi drove in icy conditions in Canada last weekend.

The Swiss driver's demonstration run in a Red Bull car on the frozen waters of the Olympic Basin, located behind the Circuit Gilles Villeneuve, was called off due to "unstable ice conditions".

But around the snow-lined Canadian GP circuit itself, and at the Lac-a-l'Eau-Claire in Quebec, Toro Rosso's Buemi got up to speed with his set of special tungsten-studded tyres.

"(It was) a bit cold but in the end, it is good to be back!" said the 21-year-old.
