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.

NASCAR Truck drivers feel the earth move sitting in NHRA powerhouses

Several NASCAR Camping World Truck Series drivers got to see how the other half lives – namely, their counterparts in the NHRA – on Thursday at Charlotte Motor Speedway and across the street at zMax Dragway.

To say it was an eye-opening experience is putting it mildly.

Top Fuel drag racers Shawn Langdon and Troy Coughlin Jr., as well as Funny Car driver J.R. Todd – all from one of the top teams in the NHRA, Kalitta Motorsports – are in Charlotte for this weekend’s 4-Wide Nationals at zMax Dragway.

NASCAR Trucks driver Noah Gragson gets to feel the 10,000 horsepower of a Top Fuel dragster.

Thursday, they invited NASCAR drivers Ryan Truex, Christopher Bell, Grant Enfinger and Noah Gragson to show how it’s done NHRA-style.

Todd, Langdon and Coughlin started the day taking Toyota Camry pace cars around the 1.5-mile CMS oval.

Then everyone moved across the street to see some real horsepower, namely, 10,000 horses worth – which is roughly about 13 times the power they have under the hood of their race trucks.

Truex and Bell got a chance to “warm up” Todd’s Funny Car, while Enfinger and Gragson did the same with Langdon’s Top Fueler.

 

Meanwhile, Todd and Langdon both did smoky burnouts that, if the Truck guys thought they could do burnouts, they learned a lot to the contrary.

“It was a cool to do a big smoky burnout,” Todd said. “It was cool to see the guys reactions. We had a great time today and I think we created several new fans.”

Added Langdon, “Days like today is what makes me love our sport even more. Bringing these guys over here and letting them hit the throttle and sit in the car when it warms up gives them a look at what we do. To see the smiles on their faces after a badass burnout and how excited they are, just gets me pumped.”

Here’s what the NASCAR guys thought about the experience.

Bell: “J.R. Todd let me sit in his Toyota Camry Funny Car and they even cracked the throttle open for me when we were warming up the motor. It is something that I will remember for the rest of my life. It is a feeling like none other.”

Enfinger: “Just a crazy experience, something I have never done. Been able to do a lot of cool things with Toyota, but it is not every day that you get to make your dad jealous.”

Gragson: “This was awesome. It was the experience of a lifetime. It was great to hang out with J.R. Todd, Shawn and Troy Jr. Definitely a cool experience; one that I will remember forever.”

Truex: “This has probably been the craziest experience that I have ever been a part of. I got to sit in a Funny Car; they hit the throttle, which really scared me. When I was outside the car, I jumped about three feet in the air. It was cool to get inside and experience that. The nitro was all in my face, and I think they gained a new fan with me today.”

F1 drivers split on new ‘shield’ protection

SOCHI, Russia (AP) Formula One drivers are split over plans to test a new “shield” device to protect against flying debris.

The FIA will trial the transparent screen in the coming months for a potential introduction in 2018, as it pushes for greater head protection for drivers. Recent years have seen major head injuries in several motorsport series.

“I wouldn’t mind trying out the shield, seeing how is the visibility,” Mercedes driver Valtteri Bottas said on Thursday. “In terms of safety it would be a good step compared to what we have now.”

Red Bull’s Daniel Ricciardo was another supporter, saying “we’ve still got to see a bit more, but first impressions seem OK.”

The FIA previously seemed to favor a metal frame known as the “halo,” which was designed to stop a flying wheel hitting a driver’s head but was criticized by some drivers on aesthetic grounds.

Toro Rosso’s Daniil Kvyat said on Thursday he was “quite against” the shield and the halo. “The way Formula One should look should remain the same,” he added. “We have enough protection.”

Romain Grosjean of Haas voiced concern the “next step” would be completely closed cockpits.

Recent years have seen several high-profile head injuries, including the deaths of Formula Two driver Henry Surtees in 2009 when he was hit by a loose wheel and IndyCar driver Justin Wilson, who was struck by debris, in 2015.

In Formula One, Brazilian driver Felipe Massa missed the second half of the 2009 season when a loose spring from another car hit his helmet, leaving him needing surgery.

Haas changes F1 brake supplier ahead of Russian Grand Prix

Haas has switched from Brembo to Carbon Industrie brakes ahead of this weekend’s Russian Grand Prix in a bid to remedy its long-running braking issues in Formula 1.

NASCAR team co-owner Gene Haas took his eponymous operation onto the F1 grid in 2016, with Romain Grosjean scoring all 29 of its points through its debut season.

Grosjean and then-teammate Esteban Gutierrez had their efforts spurned on a number of occasions by brake issues which continued to arise through pre-season testing in 2017 and the early races.

Haas pushed to remedy the issue by testing new Carbon Industrie brakes in the post-Bahrain Grand Prix test, with Grosjean and new teammate Kevin Magnussen conducting running.

The team duly decided to fit the new Carbon Industrie brakes for this weekend’s race in Russia, with both VF-17 cars to run with them from Friday onwards.

“To be fair to Brembo, the last update in brakes we had that arrived in China were much better. It took a long time to get them,” Grosjean explained.

“So then I was not screaming to change to Carbone Industrie but it was in the pipeline, so we tried them, and both drivers were pretty pleased with them. We felt like we had more control under braking.

“I’m very sensitive to my left pedal, so I really need to get good brakes to get good confidence and push the car to its maximum limit. So we are going to run them here.

“There is still a little bit of work we need to be doing around the mapping and finding the solution around those brakes but I think yeah, definitely it’s going to help me a little bit to find the last few hundredths.”

Alexis DeJoria will miss this weekend’s NHRA Four-Wide Nationals in Charlotte, with her Kalitta Motorsports team confirming DeJoria will need to tend to a family matter.

Chad Head, Kalitta Motorsports Director of Safety, will step into the Tequila Patrón Toyota Camry this weekend. No timetable was given for DeJoria’s return; after Charlotte this weekend, the NHRA Mello Yello Drag Racing Series continues for its third consecutive race weekend next week in Atlanta.

This isn’t the first race DeJoria has had to miss recently, as she also was diagnosed with a concussion and missed the 2016 NHRA season finale in Pomona.
