Contrasting strategies at India show why Vettel continues to win

1 Comment

The Indian Grand Prix proved to be another fascinating tactical battle between teams and drivers, showing that there’s often more than one way to get the best out of a race situation.

When the teams ran in Friday’s free practice sessions, it quickly became clear that the two nominated tire compounds had vastly different characteristics. The soft tire, or option, delivered a lap time around a second faster than the medium, or prime, but deteriorated significantly within a handful of laps. The medium was slower, yet withstood the abrasive surface of the Buddh International Circuit and showed almost no signs of degradation or wear for long spells, even on heavy fuel loads.

This all meant that race strategy, even more so than normal, had to be planned out before qualifying on Saturday afternoon.

The two most obvious race strategies were to qualify, and therefore start the Grand Prix, on the faster option tire, run that for a short spell, before doing two long stints on prime to the end; or conversely qualify and start on prime, even though it meant taking a hit on lap time and therefore grid position, before another stint of the same and switching to the options right at the end of the race.

There wasn’t much on paper between the two, but in fact most simulations had the latter version coming out as being slightly quicker by four or five seconds over the course of the entire race. Both were therefore feasible options and a few teams chose to cover both bases and split their two drivers.

You might ask why, if one strategy shows up as being four seconds faster than another, doesn’t everyone just go with that one?

There’re many factors to be taken into consideration before deciding on race plans, some aren’t always obvious to the outside world.

First, teams need to look at their two drivers and pinpoint their individual strengths and weaknesses. If one driver is clearly better than the other at looking after tires, he could manage a longer stint on options, or even in extreme cases, look at one less stop than his teammate. We saw this in Japan between the two Red Bull drivers.

Another consideration is a driver’s ability to cleanly overtake the pack if he comes out into traffic after a pitstop. Again, we saw the difference between Sebastian Vettel and Mark Webber in Japan when both of their strategies needed them to catch and pass Romain Grosjean’s Lotus. Vettel did it quickly and cleanly, without losing time or hurting tires behind his rival. Webber spent two laps fighting under the Lotus’ rear wing and lost time on the track to his teammate, but took valuable life from his Pirellis, which meant his strategy failed.

The ability to deliver a qualifying lap late in the session, under pressure and without the need to do multiple runs will determine how many new sets of tires the team have to use in the race. This obviously has a big impact on strategy.

In India, those who qualified and started on options had already taken three laps of life from their tires before the race had even begun, those who were able to save options and then set Q3 times on primes, were able to keep a brand new set for the last race stint. On a circuit where soft tires only lasted a few short laps, that was where part of those four or five seconds difference would come from over the alternate race strategy.

The team know their drivers inside out and so the best strategy for one, may not be necessarily the best for the other.

Other factors that come into play when deciding how to approach a race include the nature of the circuit. The first one or two turns can be crucial after the race start when the field’s bunched up, adrenaline’s high and nothing’s quite up to temperature. If the run down to turn one’s short and the corner tight, a team might prefer to go all out in qualifying to be at the front and in relative safety, over a seemingly preferable race strategy that might have them on alternate tires but further down the pack, like Webber did on Sunday. While Vettel got through the first few turns in the clear and unscathed, his teammate got caught up with other cars and compromised his original plan just a little bit.

The statistical chance of a safety car at any particular circuit can have a huge impact on deciding a team’s race decisions. The chance of the safety car playing a part generally diminishes after the first two laps of any race. In India, those who started on option, like Vettel, would’ve benefited had that happened early on, enabling them to pit and ditch the soft tire, spending the rest of the race on mediums.

When Webber stopped on lap 29 today, he took soft, option tires, perhaps not the ideal tire for that part of the race, but he did it with a safety car in mind. If an incident had occurred, he too could’ve used the ‘free’ pit stop to switch back to the prime and finish the race on them. If he’d taken primes at the stop and the safety car had then come out, it would’ve ruined his Grand Prix as he’d have been forced to stop and take options, having not yet used them, and been left with an unmanageably long last stint.

In hindsight this was over-cautious. In the three years we’ve been racing in India, the safety car hasn’t yet made an appearance and at that middle stage of the race, it was highly unlikely it was going to. His fastest way to the end was to stay on primes and take the new options for a very fast, but short final stint, when the car was at its lightest and the field at its most stretched. In the end it was academic as he retired with an alternator failure.

Weather; track evolution; the amount of time lost in pitlane for each stop; the car’s characteristics like top speed or traction and many other parameters are all carefully considered before heading into qualifying. Of course depending on the outcome of Saturday afternoons, the whole thing needs looking at again, the simulation models updated with grid positions, another look at the forecasts, start performance and so on.

Many people, both at the track and back at the team’s European bases work through the night to give the drivers and engineers the best possible scenarios before Sunday’s race, but once the lights go out it’s a constantly morphing model and the team need to be able to react as the race unfolds.

Often it’s the ability to think on one’s feet, that sets a good team apart from a great one.

Raikkonen leads topsy turvy first free practice session in Russia

Kimi Raikkonen has topped the timesheets in the first 90-minute free practice session for this weekend’s Russian Grand Prix, although times are never entirely representative in this first running of the weekend on the notoriously low-grip to start Sochi Autodrom.

Naturally then it took longer for the fastest times to come in. Raikkonen posted a 1:36.074 on Pirelli’s supersoft tires, with just under half an hour remaining, which eclipsed the pair of Mercedes AMG Petronas entries of Valtteri Bottas and Lewis Hamilton, who were 0.045 of a second and 0.607 of a second behind, respectively.

Vettel was fifth without really getting a proper lap in – more than one second back of his not-under-fire but perhaps under-duress teammate – just behind Red Bull’s Max Verstappen in fourth.

This marks the last race that Verstappen will be racing as a member of Red Bull Racing for the first time, as it marks the one-year anniversary since local hero Daniil Kvyat’s first-lap nightmare here last year. The Toro Rosso driver in his special edition “torpedo” helmet he’s made this weekend clocked in 11th.

Raikkonen’s fastest time was more than two seconds up on FP1’s fastest time last year, and times will only get quicker the rest of the weekend.

Both Hamilton and Vettel got away with “moments” during the session. Early on, Hamilton had had a quick moment over the Turn 2 curbs but landed without damage. In the final 15 minutes Vettel spun as well at Turn 17, but again without hitting anything. Hamilton then ran wide at the exit of Turn 14, looping his car, but stopping it before it hit the barriers.

Meanwhile Ferrari stated both Vettel and Raikkonen are using new turbochargers this race, and didn’t cite any potential reliability concerns as a reason why.

Raikkonen’s overall best time looked set to be bettered before the first red and only flag of the session occurred in a fairly abnormal manner.

With less than 25 minutes to go in the session, a bizarre incident occurred as Esteban Ocon’s engine cover off the back of his Force India Mercedes popped off as he closed his DRS on the run to Turn 2. Ocon limped the wounded Force India back to the pit lane with no additional damage but it put the session under a red flag, which thus provided a green flag for Twitter snark.

Meanwhile the young Frenchman wasn’t the only driver with issues this session. Stoffel Vandoorne reported in a loss of power to his Honda-powered McLaren inside the final 10 minutes of the session; the Belgian has had woeful luck of late with power units, notably at Bahrain, and the team was hopeful it had made a step forward in the post-Grand Prix test there. A grid penalty would loom with another power unit change.

To start the session, Renault test driver Sergey Sirotkin, in a run-out in his home Grand Prix weekend, didn’t even get to complete a timed lap as he stopped on the backside of the circuit with a mechanical issue. Reboot attempts failed and left him without a lap, same as the driver he was filling in for in Nico Hulkenberg, who will be back in for FP2.

Speaking of, FP2 comes up live at 8 a.m. ET, 5 a.m. PT on NBCSN and the NBC Sports App.

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.”
