“Because of the high degree of tyre wear and degradation, we would expect to see a number of different strategies at work, as was the case last year – with teams deciding whether to go for a 'sprint' strategy or to do fewer stops and put the accent on endurance,” Hembery continued.
“Last year, the 'sprint' approach won the race but, with so many different parameters at work, the teams will have to analyse the data – not to mention the weather forecast – very carefully before committing to any particular tactics. Often a flexible approach works best in Canada, so we can also expect many teams to be leaving their options open, allowing the drivers to really make the difference when it counts.”
The 2012 race, run on the soft and supersoft compounds, was won by Lewis Hamilton, who stopped twice, while the second and third-placed finishers – Romain Grosjean and Sergio Perez - stopped only once. The strategy choice throughout the top ten was split half and half, with five drivers stopping twice, but the tactic did not pay off for either Fernando Alonso or Sebastian Vettel, who were both passed by Hamilton in the closing stages.
As the teams found in 2011, adverse weather conditions can also play a key role in the Canadian Grand Prix, and Pirelli will bring both its intermediate and wet compounds in the expectation of at least one wet session.
The revised medium compound tyres planned for introduction in Montreal will now not be raced until Silverstone, although each team will get two sets per car to evaluate during Friday free practice in Canada.
