With six launches now complete, only Haasf1, Williams, Red Bull and Toro Rosso remain to pull the wraps off their 2017 Formula One contenders, three of which will do so on Sunday on the eve of the first pre-season test at the Circuit de Catalunya in Barcelona Spain.

With schedules all finalized, it now appears as if one of the new cars will be a little late with Scuderia Toro Rosso announcing that their unveiling will be delayed by 90 minutes….

“Due to circumstances beyond tour control, the launch presentation of our new car, the STR12, has been delayed by 90 minutes.”

The new car will now be revealed at 6 pm local time instead of the originally planned 4:30.

“The location remains the same, the pit lane outside our garage at the Barcelona-Catalunya Circuit and the rest of the programme will follow on from the new start time.”
