Romain Grosjean ended the first day of practice for the Canadian Grand Prix with the third fastest time, whilst team-mate Kimi Räikkönen – fifth fastest in the morning – saw his afternoon session curtailed as the team investigated a brake issue on his E21.

The morning session saw a damp but drying circuit, with afternoon running conducted in cool, dry conditions. Pirelli’s wet and intermediate tyres were used in the morning; the medium, super soft and developmental medium compound dry tyres in the afternoon.

Technical programme notes:

- Both drivers ran with new, Montréal downforce level front and rear wing specifications today
- Pirelli’s wet (blue), intermediate (green) and medium compound dry (white) tyres were used in the morning session, the medium, developmental medium and super soft (red) in the afternoon
- Kimi had a brake issue in the afternoon which ended his session early

What we learned today:

- The Montréal-spec front and rear wings and related aero package work well
- The E21 looks good in damp conditions but did not display its customary high-fuel pace

Kimi Räikkönen, E21-03
Free practice 1: P5, 1:21.608, 22 laps
Free practice 2: P11, 1:15.599, 35 laps

"We improved the car through the day"

Kimi: “We improved the car through the day and by the end of the session it was ok; not ideal but certainly not a disaster either. It wasn’t easy to get the tyres up to temperature today, but it’s pretty cold at the circuit so that’s not too much of a surprise. If we can get the tyres working better it will be an improvement for sure, but it’s not going to change the world. We’ll be looking at how to get them a bit warmer for qualifying tomorrow and then see what the weather does. After that, we’ll do the best we can.”
