Pirelli’s test program for its 2017 Formula 1 tires continued in earnest at Mugello as Sebastien Buemi and Red Bull racked up the miles on Wednesday.
As part of an overhaul of F1’s technical regulations for next season, Pirelli will provide a wider, more durable tire to teams that should see lap times improve by multiple seconds.
Ferrari enjoyed the first run with the wider tire on Monday and Tuesday at Fiorano with a modified version of its 2015 car, the running being split by Sebastian Vettel and Esteban Gutierrez.
Red Bull took over the reins on Wednesday and Thursday as Formula E and WEC champion Buemi enjoyed his first F1 test in over two years.
The Swiss driver raced for Red Bull’s junior team, Toro Rosso, in F1 until 2011, but has remained in a test and reserve role since then while also racing in Formula E with Renault e.dams and Toyota in the WEC.
Buemi completed 82 laps behind the Red Bull RB12 ‘mule’ car on Wednesday, and has been putting in the laps today at the Italian circuit.
