Kimi Raikkonen won the Australian Grand Prix using a two-stop strategy, having started the race on the P Zero Red supersoft tyre and then completing two stints on the P Zero White medium tyre. His tyre strategy gave him a decisive advantage over all his rivals, with the remainder of the top six all adopting a three-stop strategy. But what could it tell us about Lotus F1’s chassis this year?
Only four drivers started on the medium tyre: Adrian Sutil (Force India), Daniel Ricciardo (Toro Rosso), Sergio Perez (McLaren) and Pastor Maldonado (Williams).
Pirelli’s motorsport director Paul Hembery said:
“We took the deliberately bold decision to come here with the supersoft tyre in order to spice up the action. We believe that this worked very well, with a variety of different two and three stop strategies just as we expected and seven different leaders. Kimi Raikkonen and Lotus understood the tyres perfectly, making a two-stop strategy work when many of their rivals couldn’t. It was a true masterclass in tyre management. Although they were often in different places on the track, Raikkonen and Lotus were effectively racing Ferrari and Alonso throughout the second half of the race, who were on a three-stop ‘sprint’ strategy. Seeing how those different approaches played out at the end was the intriguing part of the strategy, which led to a spectacular finish and three very deserving world champions on the podium. It’s also worth pointing out that Raikkonen drove the fastest lap of the race on lap 56: the penultimate lap, on medium tyres that were 22 laps old. We are very happy with the performance and durability of both compounds, particularly as both track and ambient temperatures were very low, causing a bit of graining. The conditions next weekend in Malaysia will be very different however!”
Fastest times of the day by compound:
Supersoft Medium Intermediate Wet
First BIA – 1:30.454 RAI – 1:29.274 N/A N/A
Second SUT – 1:30.710 VER – 1:29.498 N/A N/A
Third RIC – 1:30.881 ALO – 1:29.560 N/A N/A
Longest stint of the race:
Supersoft 14 (Rosberg)
Medium 30 (Gutierrez)
Pirelli called the right strategy for the race but not all the teams listened:
The winning two-stop strategy that we predicted turned out to be correct. We predicted the first stop to change from supersoft to medium on lap 14, with a second stop for medium tyres on lap 36. Raikkonen followed exactly this tactic, making his first stop on lap 9 and his second stop on lap 34.
The reality could be that the teams were very aware or leery of just how the Super Soft compound would react to their strategy. No one knows their car better than the team and perhaps they felt there was no logical way their chassis was going to be easy enough on the options in order to make a two-stop strategy work. Regardless, Lotus F1 may be gentle on tires again this year but that was their achilles heel in qualifying last year. The wet/dry nature of this weekend’s qualifying sessions may have masked a still lagging issue for Lotus F1 but perhaps a dry qualifying in this weekend’s Malaysian Grand Prix will tell us more.
