Bahrain recap: Tire tests, rare DRS failure, hot/cold temps made for wild race

1 Comment

Amid a backdrop of complaints and concerns about this seasons Pirelli tire compounds, the Bahrain Grand Prix delivered one of its most exciting yet.

Whereas the Chinese GP used the soft and medium compound tires in cooler conditions, giving a delta of nearly one and a half seconds per lap between the two, Pirelli’s choices for this race were a lot closer in performance and durability levels.

The medium and hard tires worked well here and, in the extreme heat of the desert, seemed to be the perfect selection.

The two compounds offered a choice of strategy, though of the top 10, only Ferrari’s Filipe Massa opted to start on the hard tire. It could’ve been an inspired move by the team to cover both scenarios, but we’ll never really know as a disastrous race for both drivers ended their hopes.

A rare DRS failure while running second on lap seven meant an emergency pitstop for Alonso. The DRS rear wing flap is designed to stay closed if the system should fail, but on this occasion the hydraulic actuator managed to push the flap beyond its normal 50-millimeter opening limit. This meant that, whereas the airflow over the wing would normally force the flap shut, being ‘over-center’, the aerodynamics had the opposite effect and held it in an open position.

Mechanics were able to push the wing back into its closed state at the stop, fit new tires and send him out without major time loss, but inexplicably appeared to fail to tell Alonso not to use the system and the same thing happened a lap later. Another stop to close the wing and the loss of DRS meant the predicted challenge for the win was effectively over. He did well to salvage eighth.

After a slightly strange looking tire failure for Hamilton on Saturday morning, Filipe Massa suffered a similar looking delamination to his right rear in the race, followed by a major blow out on the next set not long after. Pirelli were quick to suggest debris on the track had caused all three issues, but will investigate further in the coming days. One thing’s for sure, following much recent criticism, the last thing the Italian tire manufacturer needs is the perception that the rears weren’t capable of withstanding the heat and demands of the Bahrain circuit.

The ambient temperature, always pretty warm, did fluctuate this weekend, as did the wind speed and direction and the effect on different teams cars was notable.

Kimi Raikkonen was ominously quick in Friday practice, yet in the cooler temperatures of Saturdays qualifying struggled considerably more. The high race day temperatures meant the car came back to him and teammate Romain Grosjean and both managed brilliant podiums from lowly grid slots. Conversely, the Mercedes of Nico Rosberg worked well on Saturday to gain pole position, but found himself with a different car altogether in the hot race. Teams are still learning about the critical relationship between tire temperature and their performance levels and more importantly, how to manage them through driving styles or technical developments. Most teams now use adjustable brake duct slots to allow some of the enormous heat from the brakes to escape and soak into the wheels and tires when needed. Many of the leading teams also use a passive, hydraulically linked suspension arrangement to control the cars pitch and, or roll during braking and cornering, allowing the car to be more aerodynamically stable and less aggressive on its tires.

Kimi showed in the race that the ability to make the tires last and do one less stop than the rest can be a huge advantage.

McLaren found strong headwinds on the main straight for the race a help as they were running a shorter top gear and would’ve otherwise been held back by the rev limiter and therefore vulnerable in the DRS zone. As ever setup is always a compromise and this is something Red Bull have used in the past to aid qualifying, whilst they work on the basis that they can get so far out in front that they won’t be under attack by DRS.

Others found the strong cross winds at the higher points of the circuit unsettling the cars on turn in.

With Barcelona three weeks away (May 12) and closer to home for the teams, we can expect some significant upgrades and developments on the way.

Sebastian Vettel does not feel frustrated about Ferrari’s reliability problems at the start of the 2016 Formula 1 season, saying “it’s part of racing”.

Ferrari entered 2016 hopeful of mounting a serious challenge to the all-conquering Mercedes team, only for issues on its cars in Australia and Bahrain to limit it to a one-car finish.

Vettel’s plight continued on Friday in Russia when an issue forced him to stop out on track during practice, ultimately resulting in a gearbox change and a grid penalty.

Vettel qualified second at the Sochi Autodrom on Saturday behind pole-sitter Nico Rosberg, but will drop back to seventh for the start of the race.

“Of course I would have liked the gap in the end to have been a bit smaller but we saw in Q2 Nico in particular was very strong getting the lap in,” Vettel said.

“I think for us it was the maximum. We benefitted from what happened to Lewis [Hamilton]. I’m not sure what exactly it was, but it allowed us to go P2 which helps tomorrow with the penalty.

“We’re a bit closer starting on the clean side of the track. I think we can have a good race from there. It should be quite exciting. The car feels good. I think all weekend has been quite strong. We lost some time, but I think we made it up this morning so it shouldn’t be an issue.”

Vettel said that he does not feel frustrated about Ferrari’s reliability issues, saying that there is still a long way to go in the season.

“Not frustrated at all. Obviously it’s not nice if these things happen because they don’t make your life easier,” Vettel said.

“But equally it’s part of racing. These things can happen. They didn’t happen on purpose, they weren’t planned. We’re been pushing very hard to try and catch up which I think especially in race pace we’ve proven already this year.

“Obviously we didn’t have a properly clean race yet this year. Maybe we’ll have tomorrow, you never know, it’s a long race and a long way especially around here. There’s a lot of things that can happen.

“I think we have to wait and see. It’s still April, tomorrow is May, and there’s a long, long way to go. It’s a long championship. It’s important to do your best to get the maximum points every single time and the rest you’ll find out anyway.”

Lewis Hamilton’s run of bad luck continued in qualifying for the Russian Grand Prix on Saturday as an issue on his power unit prevented him from taking part in the final session.

Hamilton has slipped 36 points behind Mercedes teammate Nico Rosberg after the first three races of the 2016 season, with an issue on his power unit forcing him to start last in China two weeks ago.

Hamilton arrived in Sochi hopeful of cutting the gap to Rosberg, and looked set to run the German close for pole position on Saturday afternoon.

After lapping almost half a second slower than Rosberg in Q2, Hamilton was sent back out by Mercedes later in the session despite not being at risk of losing his place in Q3.

It soon unfolded that Hamilton was in fact heading out to test his power unit, and he soon reported a loss of power similar to the one that prevented him from taking part in qualifying for the Chinese GP.

As a result, Mercedes had to bring Hamilton into the pits and end his day after Q2, leaving him 10th in the final qualifying classification.

While Rosberg was able to ease to his second pole position of the season, Hamilton was left deflated, telling reporters: “I went out at the end of Q2 to get a feel and I lost the same power as I lost in China.

“There’s nothing I can do. I never give up.”

Formula 1 championship leader Nico Rosberg remains wary of the threat posed by the opposition in tomorrow’s Russian Grand Prix despite seeing chief rivals Lewis Hamilton and Sebastian Vettel both drop back on the grid.

Defending champion Hamilton was forced to sit out of Q3 in Sochi after an issue similar to the one he suffered in China arose on his power unit.

As a result, Hamilton will start tomorrow’s race from P10 at best, leaving him with a huge task if he is to cut into Rosberg’s 36-point lead at the top of the drivers’ championship.

Vettel took advantage of this to qualify second for Ferrari, but he drops back to seventh on the grid after taking a new gearbox earlier in the weekend.

Rosberg eased to his second pole position of the season by seven-tenths of a second despite only completing one fast run in qualifying, but he is refusing to get ahead of himself.

“I was just focused on myself out there, really going for it and feeling great about it,” Rosberg said.

“It’s really going really well today. From Q2 onwards it felt awesome. The others have been unfortunate today, definitely, extremely unfortunate.

“That makes my race a little bit easier tomorrow, but an F1 race is never easy. Even from where Sebastian is and where Kimi [Raikkonen] is and with Valtteri [Bottas] behind and everything, the opposition is still there.

“So I still need to keep focused and try and get the job done as good as possible.”

Rosberg was able to get out of his car long before the end of qualifying safe in the knowledge he had pole thanks to the advantage Mercedes has enjoyed at the Sochi Autodrom.

“To be honest I was quite confident that the lap was good enough out there because in Q2 Ferrari was quite far away and I knew that Lewis was not able to participate in the last part of qualifying,” Rosberg said.

“So I was very sure it was going to be enough. You never know, there’s still the remaining uncertainty so I was glad eventually when Sebastian crossed the line that it was good enough.”

Nico Rosberg will start Sunday’s Russian Grand Prix from pole position after easing to P1 in the final stage of qualifying at the Sochi Autodrom.

Rosberg arrived in Russia 36 points clear of Mercedes teammate Lewis Hamilton at the top of the Formula 1 drivers’ championship, and is chasing a seventh consecutive grand prix victory on Sunday.

The two Mercedes drivers exchanged fast times in both Q1 and Q2, with Rosberg finishing half a second clear heading into the final fight for pole in Q3.

However, there was no battle as had been anticipated after a power unit issue arose on Hamilton’s car, meaning that he could take no part in Q3.

Using the same unit that had caused trouble in China two weeks ago, Hamilton reported a loss of power at the end of Q2, forcing him to sit out of the final session.

As a result, Rosberg was able to ease to his second pole position of the season by posting a fastest lap of 1:35.417 in the final stage of qualifying.

The German went eight-tenths of a second faster than nearest rival Sebastian Vettel with his first lap in Q3, but an error on a later lap meant he could not improve on his time.

Nevertheless, it was more than enough for pole, with Vettel finishing seven-tenths of a second back for Ferrari in P2. However, he will drop to seventh for the start of Sunday’s race due to a grid penalty.

Valtteri Bottas enjoyed his best qualifying of the season to date to finish third ahead of fellow Finn Kimi Raikkonen in the second Ferrari, while Williams teammate Felipe Massa qualified fifth.

Daniel Ricciardo led Red Bull’s charge in P6 ahead of Force India’s Sergio Perez, with home favorite Daniil Kvyat finishing eighth. Max Verstappen finished ninth ahead of the luckless Hamilton in P10.

McLaren’s hopes of scoring a first Q3 berth since the end of 2014 were dashed late on in Q2 as Jenson Button missed by just one-tenth of a second. Carlos Sainz Jr. finished just ahead of the Briton in P11, while Force India’s Nico Hulkenberg followed in 13th ahead of Fernando Alonso in the second McLaren in P14.

Haas’ recent difficulties continued in qualifying in Sochi as Romain Grosjean and Esteban Gutierrez could only finish the session 15th and 16th. Grosjean struggled with the balance on his VF-16 car, sliding off the track late in the session, but managed to outqualify his teammate once again by six-hundredths of a second.

Renault once again struggled for pace in qualifying as Kevin Magnussen and Jolyon Palmer failed to make it out of Q1 once again, finishing 17th and 18th. Felipe Nasr’s new Sauber chassis did not give him the boost required to make it into Q2 as he ended up 19th. Manor drivers Pascal Wehrlein and Rio Haryanto impressed by outqualifying Marcus Ericsson in the second Sauber, who propped up the timesheets.
