High downforce wing works for McLaren in first session (FP1 interactive data)

Posted on | Author Keith Collantine

The teams were testing different aerodynamic solutions in first practice at Monza and getting very different results.

Those who set the fastest lap times, like McLaren and Renault, were among the slowest through the speed traps.

The interactive data below shows more of what we learned from the first session.

One of the most interesting developments in first practice at Monza was McLaren choosing to use a normal-style rear wing in addition to their F-duct while others used conventional Monza ‘tea tray’ rear wings.

Despite running these wings McLaren were able to set the fastest lap of the session. But it clearly hurt their straight-line speed.

The fastest driver through the speed trap was Sebastien Buemi at 345kph. Buemi tested a new F-duct for the team at Vairano on Monday and may have been using that. But as he was 6kph faster than anyone it’s likely he was helped by running in the slipstream of another car.

Even so Button was 9.2kph slower than the next-fastest driver, Nico Rosberg in the Mercedes. Button was 16th fastest in a straight line and Lewis Hamilton was 18th, clocking 328.5kph.

Other cars that set good lap times but had slower straight line speeds were the Ferraris. Felipe Massa was 19th fastest, 328.2kph, and Fernando Alonso was 21st on 327.8kph.

The Ferrari drivers mirrored each other closely in their on-track activities and there wasn’t much to choose between their lap times, despite Massa usually faring less well on the hard tyres.

Robert Kubica, who set the fourth fastest lap time, was only 20th fastest through the speed trap, at 328kph. Look out for these teams trying more conventional Monza aerodynamic solutions in the second session.

Interestingly, Sebastian Vettel was fourth-fastest at the speed trap at 336.3kph – not an area that has been a Red Bull strength.

We’ve still got some way to go before we start seeing the best times this weekend. Vettel did his quickest lap at the end of a six-lap stint on 20-lap-old tyres.

Also, these were the hard compound tyres, not the mediums the teams had last year. Even so Button’s best time was three-tenths faster than the best time set in this session last year.
