Toro Rosso has officially launched its STR13 after posting a teaser image online last week.
The car will be driven by Pierre Gasly and Red Bull returnee Brendon Hartley with both taking alternative days at the first pre-season test which starts on Monday.
With Toro Rosso taking over Honda’s engine supply, many believe it will be a difficult year for the Red Bull junior squad unless Honda pulls something out the bag.
