Formula 1 Teams and Drivers report from Barcelona shakedown after Day 1

Seven teams took part on the opening day of the test at Barcelona: Mercedes, Red Bull Racing, Racing Bulls, Alpine, Haas, Audi, and Cadillac.

Isack Hadjar posted the fastest time in the RB22 while Esteban Ocon accumulated the highest number of laps in the Haas VF-26.

Mercedes were solid in terms of mileage which can also be said about Red Bull and Racing Bulls given their new Red Bull Ford Powertrains power unit, the DM01.

On the other hand, Audi and Cadillac struggled to put in some useful running after being hit with several issues

Kimi Antonelli: "It was nice to be back in the car this morning and, more importantly, we've had a productive first day here in Barcelona. There is lots for us to learn with these new machines so it's important that we complete as much mileage as we can and build our knowledge. The team at Brackley and Brixworth have done a great job to get us to this position, developing and building a car that has been able to complete over 150 laps on its first proper day of running.

"It is early days though. There will be things we discover in the coming days that we can improve but that is the point of testing. For now, though, the package overall feels good, and we will look to build on this start over the following two days of running we're allowed here in Barcelona."

George Russell: "It's great to be back out on track driving an F1 car once again! The cars looked really cool out on the circuit and that's positive for our sport. They are quite different for us as drivers but, once you get your head around it, driving them is quite intuitive. It's enjoyable being behind-the-wheel and I think there's a lot for fans to look forward to with these new regulations.

"We are pleased with our day, but I've also been impressed by several other teams too. The Red Bull power unit has completed a lot of laps which, given that it's their first engine they've built, means they've clearly done a good job. Haas also managed a similar amount of running to ourselves, so the Ferrari power unit has also put together plenty of mileage. It's not quite how it was in 2014! The sport has evolved so much since then and the level, in every single aspect, is so high now."

Andrew Shovlin, Trackside Engineering Director: "We are happy with how today went overall. The main thing we are looking for in the early running of any new car is to make sure we can get plenty of laps in. That enables us to get into the learning of our programme in subsequent days. Today was all about understanding the car, therefore, making sure it stabilised at the correct temperatures, and ensure we could do our long runs. It is positive that we were able to achieve that.

"It has been a monumental project to get this car ready both on the chassis and Power Unit side; at Brixworth they have been working on this for years. We don't know where we stand in terms of performance, but we've proved we are able to keep the car out on the track and that is testament to the hard work of everyone at both our factories."

Franco Colapinto: "Firstly, it's a good feeling to be going into my first Formula One pre-season with a new car. It's very different with the new regulations, such big changes, and that is very exciting for everyone. The team has done a great job in preparing everything in order to have the car ready to run on the first day of the shakedown here in Barcelona. There's always a lot to learn at this stage of the year with so many new things to understand. It's nice to see so much positivity and optimism in the garage and to see everyone putting in a lot of effort. We have two more days to run on-track here where we need to add more mileage and complete more laps. We will focus on ourselves, continue putting the hard work in, keep the energy positive and aim to make the most of this week's shakedown."

Steve Nielsen, Managing Director: "First of all, well done to the whole team trackside and at the factory for getting the car on track almost immediately when the light went green at the end of the Pit Lane on the first day of the Shakedown. It really is testament to their hard work for getting us into this position to hit the track at the first available opportunity in this new regulation era and new era for the team. After the Filming Day last week in Silverstone with Pierre driving the A526 for the first time, today was Franco's turn in the car. In the end, it was a typical first day of a test session, going through various programmes and systems checks. We experienced a few minor issues that set us back but are to be expected with a completely new car. At these events, the task is primarily about learning and understanding, rather than rushing too much too soon. So, today has largely been a thought-out decision to limit some of our running at times in order to ensure our systems and processes are running correctly. We have two more days in the car for the week, which we'll decide based off a number of factors including weather and the conditions, where we will aim to maximise our track time and continue to learn more about the entire package."

Esteban Ocon: "First off, it's been an unbelievable effort from the whole team to get the car ready and out on track at 09:20 this morning. We were ready at 09:00 but wanted to see an improvement in track conditions and some other things just to be perfect before we went out. From the Fiorano run out with Ollie on Saturday, to being here running from the morning today, people have moved mountains to make it work. We've worked through our plan, we've learned as we've progressed through the day – and of course it's a busy plan obviously focusing on getting mileage onto the car. We'll keep pushing to make sure all the details are covered, but at least this year we have more days than usual. We'll see what we can improve, so we can ensure that we take the right development path and put the resources where they matter the most. For the first real day of driving a new car though, I think it's gone well."

Ayao Komatsu – Team Principal: "In terms of the mileage we've been able to do today it's been really good, but behind the scenes it's been a huge amount of work – I'm sure it's been the same for everyone. To have completed Saturday's full permitted mileage at Fiorano was monumental, and then to come here and be ready to run first thing Monday in Spain, it's been an incredible effort from the whole team and honestly very satisfying to achieve. As the day's progressed, we've been able to start to look into the details more, but with these new regulations it's just been so important to be running – every time we go out we learn something new, that's what we're here for. We're gathering data and identifying issues that need to be solved, but we're only getting started. That said, I'm happy with how we've started this week. We all have a huge challenge ahead of us but you'll see a lot of evolution through testing and then through the season which will be interesting for everyone."
