The first pre-season test of 2018 was a memorable week. When the paddock was greeted by freezing temperatures on Tuesday morning and a thin layer of snow on Wednesday, it was clear that the best laid plans of all ten teams would go awry. As is the nature of Formula One, the paddock made the best of a bad situation but the majority of the big questions ahead of the new season remain unanswered.
Why did the cold weather have such an impact?
The seasonal average temperature at the Circuit de Catalunya in late February is 15 degrees Celsius, but for the first three days of testing the mercury struggled to rise above zero when the pit lane opened.
