Mercedes drivers were placed fastest times on the average frame while using McLaren smoothly for their weapons.
Norris was testing a new front suspension design aimed at improving the feeling of “numbness” in the front axis that affected his ability to trust the car in the absolute limit in the qualifiers this season.
The upgrade was available to both drivers, but Norris only used it on Friday. PiaSSTRI was more comfortable with the front of the vehicle's front, and partially explained the shift in the shape between them since last year.
The Lance Stroll of Aston Martin crashed early in the session, the barrier hit a great blow to a way out of the Seven Seven and broke his left front hanging.
His car suffered a retreat at the exit of the corner and washed the front in the wall. Stroll had witnessed the situation earlier in the roll, but it exacerbated the accident by “Air Dirty” from the traffic forward.
A number of other drivers have offended the braking points and surpassed the grass in one of Chicanis without any damage.
Franco Kulapinto of the Alps was the second a day per day, after a precedent in the first session. The Argentine ended the second session slower than the drivers who set time.
