The last action ahead of Formula One's summer break is taking place at Mugello on Thursday as Red Bull completes its second day of testing with Pirelli's 2017 tyres.
After Ferrari debuted the new wider rubber at its private test facility Fiorano on Monday and Tuesday, Red Bull hit the track on Wednesday with the latest prototype tyres attached to its mule car and test driver Sebastien Buemi at the wheel. The mule cars have been adapted from a 2015-spec chassis to run with a wider track and to accommodate the new tyre dimensions, which are 60mm wider at the front and 80mm wider at the rear than F1's current competition tyres.
From the handful of photos released from Wednesday's test, Red Bull's mule car did not appear to be running a wider rear wing like the one Ferrari had equipped its SF15-T with on Monday and Tuesday.

The next time the 2017 tyres will hit the track will be on September 6 as Ferrari and Mercedes commence parallel tests at Barcelona and Paul Ricard respectively. Ferrari's test will last for two days whereas Mercedes will test for three; both tests will be used to develop the slick tyres.
