Breꩵndon Hartley will switch to a new, permanent Formula 1 car number for this weekend's Mexican Grand Prix after using Toro Rosso's reserve number for his debu💛t last weekend.

Porsche LMP1 driver Hartley was drafted in by Toro Rosso to make his F1 debut in the United States G🦩rand Prix last weekend in place of Pierre Gasly, who was ruled out due to a clash with the Super Formula finale at Suzuka.

Hartley enjoyed a solid first outing for Toro Rosso, finishing 13th, and was swiftly confirmed to be returning fo🍰r the final three races of the season in place of Daniil Kvyat, who will not return to the team.

Hav๊ing raced with #39 in Austin, Toro Rosso's designated reserve number, Hartle🔴y will now switch to #28 from this weekend's race at the Autodromo Hermanos Rodriguez.

""I'm so excited to head t🎉o Mexico for my second Formula 1 Grand Prix. It was a steep learning curve in Austin last week, so I'm looking forward to put🔥ting some of the lessons learnt into practice this weekend here in Mexico," Hartley said.

"It's a tricky venue for the engineers, as the high altitude plays havoc 🌜on downforce and cooling, but from a driving po𝕴int of view it's a great track and one I really enjoy."

#28 was previou🍎sly used by Will Stevens during his sole full season in F1 with Manor back in 2015.
