Although Lando Norris set the pace on the opening day of testing at the Circuit de Barcelona-Catalunya as he took his McLaren around the track in 1m19.568s on the Soft (C4) tyre, McLaren were actually one of the teams to accumulate the least mileage over the day.
With sheer lap count being a primary goal of pre-season testing as teams strive for mileage to better understand their new cars, there were a few clear winners on the opening day of action.
Ferrari finished in second and third place on the timing sheets, but their cumulative 153 laps between Carlos Sainz and Charles Leclerc has given the engineers plenty of useful data to pore over.
Red Bull were in second place, with 147 laps in total completed by Max Verstappen, as the Dutch driver kicked off his World Championship defence by putting in a full day behind the wheel.
Williams, underlining how far they have come in recent seasons after their testing troubles of three years ago, achieved the third highest lap count as Nicholas Latifi and Alex Albon delivered 132 laps of Montmelo between them.

Verstappen the most productive driver
In terms of the individual lap charts, Verstappen led the way as one of only four drivers to complete a full day at the wheel.
Yuki Tsunoda, Fernando Alonso (after some confusion as to who was driving the Alpine) and Norris all spent the day on track and unsurprisingly join Verstappen towards the top of the rankings.
Charles Leclerc completed the most laps (80) out of the drivers who spent half a day at the wheel, while George Russell, Sainz, Lance Stroll, Albon and Latifi also completed race distances at the venue.
