Day One 
Driver: Felipe Massa
Chassis / Engine: FW40-01 / Mercedes-AMG F1 M08 EQ Power+
Location: Circuit de Barcelona-Catalunya, 4.655km
Weather: Warm and Dry
Maximum air & track temps: 21ºC / 26ºC
Rod Nelson, Chief Test & Support Engineer:
It was a very good day. It was a fillip for the guys who have been working on the car. We had a very straightforward day, particularly in the afternoon. We did some pretty good tests – short runs, long runs, compared the soft and medium tyres. We are still getting to know the FW40, so it is an interesting time of year and it is looking pretty reasonable at the moment. There is a massive amount to do, particularly this year with the huge regulation changes. The tyres are going to take a lot of time getting to learn with the different compounds and sizes. There is a good chunk more downforce on the car. It’s a change for the drivers as their driving technique is quite different with this amount of grip, and the way we look after the car is different too, however the winter preparation seems to be paying off. 
Felipe Massa:
Today was a good day. The first day of the test is always one where you hope everything on the car works well and that it’s reliable, and with 103 laps on the board I’d say that wasn’t bad at all. In the morning, we made a few set-up changes and checks so we knew that everything on the car was working in the right way. There was some waiting around whilst that was done thoroughly. That said, the lap count racked up in the afternoon after all those initial checks and changes were carried out. It’s early to say where we are whilst we’re still in this learning stage, but I’m really enjoying driving. There’s much more grip and they go much quicker in the corners. We can brake much later and reach high speeds much quicker. Overall, it was a great first day which is really positive for the whole team. We completed more than 100 laps and I really hope we learn new things day by day and prepare ourselves as best as we can for the first race in Australia

Day Two  
Driver: Lance Stroll 
Chassis / Engine: FW40-01 / Mercedes-AMG F1 M08 EQ Power+
Location: Circuit de Barcelona-Catalunya, 4.655km
Weather: Cool and Dry
Maximum air & track temps: 16ºC / 24ºC 
Rob Smedley, Head of Performance Engineering:
Lance was on lap six of his second run when he had a spin. The grip was particularly low and so he spun and went through the gravel backwards. Even though the accident was entirely innocuous we’ve unfortunately had quite a bit of accident damage, which we’re now in the process of repairing. We’re having to send some composite parts back to the factory, which will be back with us at some point tomorrow. We’re doing the upmost we can now to get back out on track at the earliest opportunity tomorrow. We will be able to recover the program in the coming days.
Lance Stroll: 
It is still early days and I have only done a handful of laps. I am just getting to grips with the FW40, and there is still a lot of time ahead of us. It was good to finally get behind the wheel to just get a feel for it. Like I said, it is still early days, so I need to do a lot more running before I know exactly where I am and where the car is at. I will have a much better picture once we have more laps under our belts, but it was good to break the ice and I am looking forward to some more running.
