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.

Ricciardo confident Red Bull hasn’t missed last F1 win chance in 2017

Red Bull Formula 1 driver Daniel Ricciardo is confident the team has not missed its last chance to win a race in 2017 after losing out to Mercedes’ Lewis Hamilton in Singapore.

Red Bull ran strongly throughout the Singapore race weekend, with Ricciardo boldly stating the team would win after qualifying third for the race.

A wet-dry affair marred by a start-line crash allowed Hamilton to sweep from fifth to first, while Ricciardo was left to settle for P2 for the third straight year in Singapore.

With none of the remaining circuits appearing to suit Red Bull’s RB13 car as well as Singapore, Ferrari and Mercedes are expected to share the spoils through the final six races of the year.

However, Ricciardo is sure that Red Bull will get another opportunity to add to its surprise victory in Baku earlier this season, which came about in surprising circumstances.

“Malaysia, obviously there were a few incidents last year but I think our general pace wasn’t too bad so we might be stronger than we think there,” Ricciardo said, looking ahead to next weekend’s race in Kuala Lumpur.

“Malaysia, Japan and then we’ll see. I think we can be podium cars, probably Malaysia, Japan, Austin.

“We might need some alternate conditions to really give us raw pace to fight for a win.

“I’m not going to sit here and say we’re not going to win one.

“I believe we’ll get at least one chance somewhere.”

F1 teams allowed to use current-year cars for demos from 2018

Formula 1 teams will be allowed to use their latest-spec cars at demonstrations organized by the sport from 2018, the FIA has confirmed.

F1 hit the streets of London, England ahead of the British Grand Prix in July for a live demonstration that attracted a crowd of over 100,000 fans.

Due to restrictions on the use of current cars outside of official testing and grand prix weekends, all teams were required to appear with older chassis models in London, most coming from 2015, the most recent year allowed to be used freely.

The restrictions meant that Haas, which only became an F1 team in 2016, could not field a car at all in London.

As part of the updated sporting regulations approved by the World Motor Sport Council and issued by the FIA earlier this week, a rule tweak was confirmed to let teams use their current-year cars at “demonstration events organized by the Commercial Rights Holder”.

Teams are still allowed to complete two filming day events with their current cars, with the majority opting to use one prior to pre-season testing to act as a shakedown of their new models.

While no further demonstrations such as the one in London have been confirmed by F1 yet, they are understood to be in the works after the success the July event enjoyed.

Maverick Viñales will start Sunday’s MotoGP race at Motorland Aragon from pole position after topping qualifying for Yamaha as teammate Valentino Rossi made a stunning return from injury.

Having broken his leg during a training accident at the end of last month, Rossi was cleared to race this weekend by MotoGP’s medical officials on Thursday, with the nine-time world champion gingerly returning to action in practice.

Rossi battled through to Q2 by finishing final practice 10th-quickest, before then producing a rapid final lap in the session to secure third place on the grid for Sunday’s race.

Teammate Viñales bagged his fifth pole of the season with a best lap of 1:47.635, lapping one-tenth of a second quicker than Ducati’s Jorge Lorenzo. Rossi was a further 0.08 seconds behind in P3.

Cal Crutchlow took fourth for LCR Honda ahead of Marc Marquez, who fell ahead of his final run and was unable to improve his initial lap time in Q2.

Marquez’s chief title rival Andrea Dovizioso will start seventh behind Dani Pedrosa, while Aleix Espargaro, Alvaro Bautista and Andrea Iannone completed the top 10 in qualifying.

McLaren ‘a little behind’ on 2018 F1 car plans after delayed engine call

McLaren racing director Eric Boullier has conceded the team is “a little behind” in developing its Formula 1 car for next year after only finalizing its 2018 engine plans last week.

McLaren saw its long-running engine saga end in Singapore when it agreed a deal to end its current Honda supply and link up with Renault from the start of next season.

The move is expected to give McLaren a lift in performance and allow it to fight further up the field, but the delay in being finalized has put the team slightly behind schedule in developing its new car.

“We are flat out working on the 2018 car. There are a lot of changes in terms of layout of the engine, so we have to redesign some of the parts we already had in our mind,” Bouller told the official F1 website.

“We are a little behind in terms of decision. I would have loved this decision to have been made a couple of weeks ago.”

McLaren will no longer enjoy exclusive works status in 2018 as it has done with Honda, with Renault also supplying engines to Red Bull and its own factory team.

Boullier remains confident of a strong partnership between McLaren and Renault, though, and is sure it is the best path for the future.

“We are ‘privileged customers’ with Renault. We have the same engine and access to information as Enstone or Red Bull Racing, so this is a real partnership with Renault,” Boullier said.

“We also have the possibility to work with them – to put ideas in the box for the future that might be taken into consideration. That will allow us to influence in the future. But yes, a full works team is different from our situation in 2018.

“But it is like in school: you look at the plusses and the minuses, and looking at all the plusses and minuses we made our decision, which we believe will be the best one for McLaren for at least the next three years.”
