Toro Rosso driver Brendon Hartley has ruled out competing in other motorsport categories this season, saying he will solely focus on Formula 1.

The New Zealander made his F1 debut at the backend of 2017 as a replacement for Pierre Gasly and the Faenza-based squad have opted to retain him for the upcoming season.

Hartley, though, has been competing in the World Endurance Championship for the last six years and many were wondering if he would again take part in the 24 Hours of Le Mans after winning it with the Porsche Team last year.

However, the 28-year-old will prioritise Formula 1.
