One stop strategy was the unconventional strategy at the Canadian Grand Prix, and it worked differently for different drivers. Fernando Alonso who lead the race twice, couldn't manage his tyres properly and finished in 5th place. At the same time, Sergio Perez who started the race down in 15th place scored his second podium with a 3rd place finish. So, in this strategy analysis, we tell you how Alonso and Vettel got their one stop strategy wrong and lost their podium places to Grosjean and Perez who in turn beat them with the same strategy.
Vettel vs Hamilton vs Alonso
Vettel got a clear start and made a small gap to Lewis Hamilton and rest of the field which ranged from 1.5 to 2.5 seconds. Vettel was the first one to make his first stop(lap 16), Hamilton pitted the following lap and came out ahead of the former. It was so because Hamilton was able to set a quick in-lap on lap 17 while Vettel posted a slower lap as his new set of prime tyres didn't have enough heat. Alonso beat both of them when he pitted on lap 19. However, Hamilton on much warmer tyres overtook the Spaniard on latter's outlap using DRS. The order now was - Hamilton, Alonso and Vettel.
Hamilton then made a three second gap to Alonso and made his second stop on lap 50. He soon found that Alonso and Vettel were going for a single stop strategy. And Hamilton on much fresher tyres was able to overcome a 15 second gap and overtook Vettel on lap 62 and Alonso on lap 64 to regain race lead.
Vettel decided to make a late second pitstop on lap 63 having lost a position to Hamilton on the previous lap. While Alonso continued on his worn tyres. Completing 51 laps on a single set of prime tyres was always gonna be tough and Fernando Alonso lost three more places to Grosjean, Perez and even Vettel. Had both the drivers made their second stop around lap 50, they would have finished on podium instead of 4th and 5th.
Grosjean and Perez's one stop strategy
High track temperature on Sunday worked in Lotus' favour and Romain Grosjean made the most of it. He made a rather early stop for a single stop strategy on lap 21 but managed his tyres beautifully for 49 laps. He overtook Rosberg and Webber on 37th and 52th lap respectively, Vettel came in behind Groshean after his late stop. He then overtook Alonso on lap 66 to finish the race in 2nd place.
Sergio Perez started the race down in 15th place. Sauber is very light on tyres, and one stop strategy was the right strategy for the Mexican. Since Perez was eliminated in Q2, he was free to start the race on whichever tyres he like. He chose the prime tyres and his first stint lasted 41 laps. He came out in 8th place after his stop and overtook Rosberg and Alonso on track, and Massa, Webber and Vettel came behind him after their pitstops. The Mexican thus went on to finish in 3rd place, his second podium of the season and career.
