Bahrain Grand Prix: Renault Sport F1 Practice report 5 April, 2014 116 Renault F1 Sport report from the first day of free practice of the Bahrain Grand Prix weekend, Round 3 of the 2014 Formula 1 World Championship, at Sakhir; Key practice points: F1 back in Bahrain after two pre-season tests. For first time in its history, Bahrain Grand Prix will be run in night conditions under floodlights. FP2 was therefore run after sunset. Infiniti Red Bull Racing’s Daniel Ricciardo finished FP2 in fourth, with Sebastian Vettel 7th. Scuderia Toro Rosso continued their top 10 pace. Lotus F1 Team completed significant mileage. Lots of laps on the board for Caterham F1 Team; overall Renault powered cars complete 429 laps of the Bahrain International Circuit. Rémi Taffin, head of track operations: ‘It’s good to be back in Bahrain [and] in better shape than in winter testing.’ Across all our teams we have covered a lot of mileage, more than 2,300 km – equivalent to one race distance per car, and collected a lot of information that we can use for the rest of the weekend. Compared to where we were just one month ago, this is clearly a big step forward in reliability, although we are still not where we want to be in terms of performance. We saw a big drop in temperatures between the first and second session, in the order of around 10 °C track and ambient temperature. While this has not necessarily affected the PU set up or maps used, it does have an impact on the cooling level and inlet temperatures so it’s something we have to monitor very closely to stop any issues occurring. There have been a lot of positives from today. The pace of the Red Bulls on the longer runs is strong and we had no major issues. Both Lotus cars were also able to complete a lot of mileage. Romain reported a misfire in FP2, which we later traced to a problem with the wastegate. We will fix this overnight to work on pure performance with the team tomorrow. Toro Rosso again had a strong day in the top 10. The only issues were relatively small: an oil leak in FP1 and then issue on the wastegate for Daniil in FP2, but once both were identified they were easy to fix and did not impact the programme. For Caterham it was again a day of two halves. While Kamui’s car worked fine, there were problems on the ERS and then MGU-K on Marcus’ car, which ultimately put paid to his day in FP2. We’ll change the parts overnight to hope for a better day tomorrow. Overall however it’s been a productive day with lots of data and mainly clean running, which means we can look to work on performance tomorrow. Subbed by AJN.
