Race12 – 44 Laps – 7.004km per lap – 308.052km race distance – low tyre wear

Belgian GP F1 Strategy Report Podcast – our host Michael Lamonato is joined by Phil Horton from Motorsport Week.

Formula 1 returned to action at Spa-Francorchamps after the seemingly never-ending summer break, and the iconic track hosted another action-packed and exciting race.

Lewis Hamilton started from P1 on the grid after smashing the lap record and matching Michael Schumacher’s all-time pole position record of 68, looking in command throughout the race.

He withstood pressure from title rival Sebastian Vettel and negotiated a safety car restart well to hold onto first place and pick up his third Belgian Grand Prix victory, as well as his fifth of the season.

Vettel picked up second place, his championship lead being cut to seven points, with Red Bull’s Daniel Ricciardo making a late charge to third – ahead of Kimi Raikkonen and Valtteri Bottas.

Spa is the longest track on the F1 calendar and threw up a range of different strategy stories. Here are the main strategic headlines from the Belgian GP:

Hamilton pits first

Interestingly, race leader Hamilton was the first of the frontrunners to pit for a fresh set of tyres, diving into his box on lap 12 and going for the soft tyres. It was a lightning-quick stop of 2.3 seconds. Ferrari kept Vettel out two laps longer to try the overcut, feeling his tyres and pace were good enough to continue.

However, his stop wasn’t quite as quick as Hamilton’s, and strong outlaps from the Mercedes gave him a slightly increased advantage after the first round of stops. With both drivers going onto the soft tyre, it appeared they were going for a one-stop, which seemed to be the slightly quicker strategy.

A mix of tyres

Interestingly, all three tyre compounds worked well at Spa, meaning all of them were used for the first stint. Pascal Wehrlein was the only driver to start on the softs but he retired early on, meaning we didn’t get to see what strategy Sauber were going for with that decision.

Felipe Massa, Lance Stroll, Daniil Kvyat, Stoffel Vandoorne and Marcus Ericsson all opted for the super-soft tyres for the first stint, looking to go longer on the more durable and less grippy tyres. However, a few of them pitted before the ultra-soft runners.

This was either because they expected a virtual safety car or safety car from Max Verstappen’s stopped car or wanted to ditch the super-softs, as they weren’t working as well as expected, and looked to go onto a different tyre.

Kimi ruins his race

Kimi Raikkonen’s chance of a podium took a big hit with a 10-second stop/go penalty for failing to slow for yellow flags, when Verstappen retired. This cost him time and track position, which proved costly further down the line.

On the replays, it was clear Raikkonen failed to lift through the yellow flags, and Raikkonen had to serve the stop/go penalty on its own, as the team were expecting a one-stop race. Had he lifted under yellows, he would’ve been in a better position to score a podium.

Safety car shake-up

The deployment of the safety car proved to be perfectly-timed. It was brought out due to the amount of debris from Sergio Perez and Esteban Ocon’s contact, at a pivotal time in the race. One-stoppers could effectively get a ‘free’ stop and avoid the possibility of degradation and wear at the end of their final stints.

It came out at a prime time for those stopping for a second time, therefore fitting into their strategy and giving them a free stop too. So, it worked out quite well, although it didn’t particularly mix up the order.

However, it did give us a fascinating prospect – a late sprint to the flag. All three tyre compounds appeared for this final stint, with the two leaders going for different strategies. Hamilton was on the softs, Vettel on the ultra-softs.

This gave Hamilton more tyre life, but Vettel had more performance and the threat of running out of tyres towards the end of the race. The ultra-soft was around one second quicker than the softs but Vettel couldn’t find a way through on Hamilton, and probably lost time trying to follow the Mercedes so closely.

In the end, Vettel couldn’t get close enough, with Hamilton taking the win and Vettel fading slightly in the closing laps.

Ricciardo fights back

With Verstappen retiring, that left Daniel Ricciardo in fifth place. He moved up to fourth with Raikkonen’s stop/go penalty and went onto the super-softs for the second stint, clearly going for a two-stop. The safety car helped effectively give him that second stop for free.

Red Bull gave him ultra-soft tyres for the last stint and this allowed him to attack on the restart, passing Valtteri Bottas for P3. The Mercedes ran wide and lost a place to Raikkonen as a result. Ricciardo’s fast reactions and speed on the restart proved pivotal in him scoring a podium.

Two lots of contact

Force India’s two drivers had a messy race after colliding with each other twice. On the first lap, Sergio Perez was running alongside Nico Hulkenberg on the run to Eau Rouge when Esteban Ocon joined the party. Perez moved across and squeezed Ocon against the wall.

On lap 30, the two clashed at a similar point on the track, Ocon trying to make a move and Perez moving across. The resulting contact gave Perez a puncture and Ocon damaged his front wing, which the resulting safety car helped with.

But, the clashes cost Force India a double points finish, as Ocon recovered to ninth and Perez was down in 17th. Both were running well within the top 10 at the time of the second clash.

Race11 – 70 Laps – 4.381km per lap – 306.630km race distance – low tyre wear

Hungarian GP F1 Strategy Report Podcast – our host Michael Lamonato is joined by Abhishek Takle – F1 Journalist.

Formula 1’s annual visit to the Hungaroring featured a fascinating, but not particularly thrilling, 70-lap race. Ferrari took a controlled 1-2 finish, with Sebastian Vettel picking up his second Hungarian Grand Prix win, ahead of Kimi Raikkonen.

The first lap was frenetic and fast-paced, before an early safety car neutralised the action. It started to become a bit processional during the mid-part of the race, but it all came alive towards the end as the top five closed up.

Unfortunately, with the circuit being notoriously difficult to overtake on, the order largely remained the same – apart from Lewis Hamilton letting through his team-mate Valtteri Bottas. But, it was a much more intense way to end the race.

High temperatures and slightly heavier tyre degradation predictions indicated a two-stop strategy could possibly be the quicker option, but in the end, it proved to be a much more straight-forward race. Here are all the major strategy headlines:

Naughty Verstappen

Of course, one of the biggest stories from the Hungarian GP was the first-lap contact between Max Verstappen and Daniel Ricciardo at Turn 2. It took Ricciardo out of the race with damage and fluid pouring out of his car, while Verstappen managed to continue on, with a 10-second time penalty.

Verstappen and Ricciardo were side-by-side going into the corner. But, Verstappen locked up, ran deep and slammed into his team-mate. The resulting time penalty proved costly for both drivers, as Red Bull’s pace really came alive in the race – as Verstappen showed.

For much of the first stint, Verstappen was ahead of Lewis Hamilton, but the RB13 looked after its tyres very well – as we have seen before – and he went longer on his pitstop. But, of course, with his penalty, he dropped well behind Hamilton after his lap 42 switch to softs.

But, with not only fresh tyres but good pace, he was able to quickly close on Bottas, Hamilton, Raikkonen and Vettel, and ended up finishing only 13-seconds off the lead. Imagine what could have been possible without the penalty? A podium, for sure.

Team instructions…

Hamilton soon caught Bottas after the pitstops and was clearly the quicker of the two at the time, so Mercedes told Bottas to let his team-mate through and give challenging the Ferrari drivers a go. He did, but frustratingly, after a long stint hunting them down, he couldn’t get close enough to try a move.

When Hamilton had gone past Bottas, he’d promised to let him back through if he was unsuccessful. Verstappen was closing and right behind Bottas on the last lap, but he was a man of his word and let the Finn ahead at the very last corner to take third place.

Frontrunning strategies

In all honesty, it was a pretty straightforward race for the top drivers. Bottas went first with the pitstops, diving in on lap 30, followed swiftly by Hamilton on the next trip around the circuit. Ferrari reacted but at that stage, they had a decent advantage – with Vettel and Raikkonen stopping on lap 32 and lap 33 respectively.

Raikkonen was actually frustrated that he was stopped so soon. He felt his pace was good, and he could have gone longer on those tyres. It was a feeling also felt by Hamilton, but team radio issues that were only resolved later in the race prevented him from communicating that to Mercedes at the time.

One-stop for most

Even though the temperatures were extremely high in Hungary, as usual, the early safety car neutralised the race and allowed drivers to extend their first stints – which made it a safe one-stop, in the end. The tyres held up well, with better than predicted degradation, and few drivers experienced issues.

Even though drivers had just one pitstop, there were still a number of issues during those trips to their pit boxes. Nico Hulkenberg had a particularly slow stop, as did Romain Grosjean – which caused his retirement. Even the leaders suffered slightly sluggish stops, so it wasn’t a clean or swift afternoon in the pits.

Sauber problems

It was a tough race for the Swiss outfit. During the safety car, both Marcus Ericsson and Pascal Wehrlein pitted, and it looked like a daring strategy move to ditch the super-softs for soft tyres. However, it was actually due to both picking up punctures on the opening lap, and this put them off-strategy with the rest of the pack.

Wehrlein played it safe and stopped again for another set of softs on lap 28, but Ericsson stayed out much longer. It looked like he was trying to get to the end but on lap 63 he pitted for super-softs, which ruined that possibility.

Not much variation

Unlike recent races, we didn’t see that much variation in the tyres the drivers started on. Just Paul di Resta – making his return, replacing the unwell Felipe Massa at Williams – and Daniil Kvyat took the slightly riskier strategy of lining up on the soft tyres.

In the end, the super-softs proved strong and durable enough to run at good pace without little degradation for well over 30 laps. Verstappen’s 42-lap stint was the longest on that set, and many others did impressively stretched-out first stints, while Ericsson did a mammoth 62 laps on the softs.

The medium tyre was pretty universally unloved for the entire weekend, only making appearances in Friday practice before being ditched. The softer compounds are just too durable and quick to not take advantage of.

Race10 – 51 Laps – 5.891km per lap – 300.307km race distance – low tyre wear

British GP F1 Strategy Report Podcast – our host Michael Lamonato is joined by Zach Priest from Superlicense F1 Podcast.

Mercedes driver and three-time F1 champion Lewis Hamilton was an unstoppable force at his home race, taking a dominant and record-equalling British Grand Prix victory at Silverstone.

He led every single lap in what was a lights to flag victory, but while there wasn’t much action at the very front of the field, there were plenty of entertaining battles and storylines further back – with the podium positions only decided on the last lap.

Late drama due to tyre problems prevented Kimi Raikkonen of a strong second place, with Valtteri Bottas benefitting to finish runner-up and give Mercedes a 1-2 finish. Raikkonen finished third, though, with Sebastian Vettel picking up a puncture just one lap after his team-mate.

It wasn’t the most fascinating strategic race, but nevertheless, there were plenty of interesting headlines to delve into. Let’s take a look…

Rain stays away

In typically Silverstone style, rain played its part during the British GP weekend, but it didn’t arrive for the race. Light showers disrupted the early stages of FP3 and impacted the first segment of qualifying, but the circuit eventually dried out and the sun started to emerge from behind the clouds.

On race day, there was a smaller chance of rain, but despite reports of a few drops, it never really materialised. This meant teams avoided any strategy curveballs and kept it at a straightforward one-stop race. Annoyingly, it did start to chuck it down at Silverstone after the race…

Popular compounds

As we’ve seen before, drivers largely stuck to just two of the three dry tyre compounds during the weekend – the soft and super-soft, which both proved to be durable and had similar performance levels (around seven tenths between them).

Pirelli has been very cautious with its 2017 compounds and it’s prevented drivers from using alternative strategies, with most being one-stop races. It was the same story at Silverstone, although there was a bit more of an opening for a two-stop, but this would likely leave drivers in traffic.

Vettel’s mixed fortunes

Ferrari racer and championship leader Vettel pretty much lose his chance of F1 victory at Silverstone in the first few corners, when Max Verstappen got ahead of him and into third. The Red Bull was lapping around one second slower than Hamilton and this dropped Vettel out of contention by the first stops.

However, he did move ahead of Verstappen with an early pitstop on lap 19, ditching super-softs for softs. It was a perfectly-executed undercut, with a brilliant outlap and a slightly faster stop. This enabled him to pull ahead of Verstappen, but he didn’t have the pace to hold off a charging Bottas.

The tyre issues

Pirelli has said that the tyre woes suffered by Ferrari on lap 49 and 50, for Raikkonen and Vettel respectively, are different. The Italian tyre manufacturer is now evaluating what happened. What’s clear, though, is that Vettel’s was a puncture as his tyre was completely destroyed, while Raikkonen’s still kept its shape.

The late drama cost Vettel the most, as he slipped to seventh, while Raikkonen’s tyre let go later around the lap and was still inflated so he made it back to the pits at a quicker pace. This was crucial in keeping him P3.

Bottas fights back

For the second race in a row, Mercedes knew one of its drivers had a grid penalty before qualifying and did something different to set up an attacking race strategy. Bottas set his best Q2 time on softs, which meant he started on the middle tyre compound for a long opening stint before pitting on lap 32.

By that stage, he had already made up a few spots after a good first lap, but having the supersoft tyres at the end of the race allowed him to charge up the order and enjoy some brilliant battles. Verstappen holding Vettel up early on helped, as did Raikkonen’s issue, but it was nevertheless a strong performance – to go from ninth to second.

Ricciardo’s feisty charge

Daniel Ricciardo lined up 19th on the grid after penalties and a mechanical issue in qualifying. With more tyres available, he used fresh super-softs for his long first stint, looking after the tyres well – while also battling his way past slower cars.

He had a few knock-backs, after being forced wide early on and dropping back to last, and also losing three spots in the pitstop. The Aussie made those back up though in less than two laps. He was aggressive when he needed to be, but it was also a classic drive of tyre preservation too, keeping his super-softs in good shape and giving him fresher softs for a final fight to the flag.

No points for Vandoorne

Stoffel Vandoorne enjoyed his best weekend of the season so far, making it through to Q3 and almost scoring a point. It all unravelled with a slow pitstop on lap 26, allowing Felipe Massa to undercut him – helped by the Brazilian going from softs to super-softs. Vandoorne kept with Massa though and came close to finishing P10, but it wasn’t meant to be this time.

Sauber try the ‘zero-stop’

The early safety car period on lap two opened up the opportunity to take a risk and Sauber did just that with Pascal Wehrlein. He pitted to go from softs to the unflavoured mediums, the only time the compound was used in the race, before then stopping again to go back onto fresh softs.

The SC basically gave him two free pitstops, but while tyre wear continues to be low, degradation was higher than recent races due to the demanding Silverstone circuit. This meant degradation wasn’t low enough to pull off this daring strategy and several other drivers (such as Wehrlein) had to go for a second stop late in the race.

Race 9 – 71 Laps – 4.318km per lap – 306.452km race distance – low tyre wear

Austrian GP F1 Strategy Report Podcast – our host Michael Lamonato is joined by Luke Smith from NBC Sports.

While the first and last laps of the 2017 Austrian Grand Prix were pretty exciting and action-packed, the rest of the race fell a bit flat – caused, in part, due to the lack of strategy and the durable tyres at the Red Bull Ring.

Valtteri Bottas converted pole position into his second Formula 1 victory, holding off a late charge from Ferrari’s Sebastian Vettel to give Mercedes a vital win. Daniel Ricciardo brought the “shoey” back with a podium for Red Bull on home soil.

As has been the case at a few races this year, strategy didn’t really play a crucial part in the race, with limited options. However, there were still some interesting storylines to dive right into:

One-stop for all

Sometimes, during the 2017 season, we’ve seen the one-stop strategy be the most popular – but a few drivers have tried the two-stop, just to give it a go. That wasn’t what happened in Austria, with all of the 16 classified finishers completing just one trip through the pits.

This was because the tyres at the Red Bull Ring were incredibly durable, and there was little difference in terms of grip and speed. In fact, it was the closest we’ve seen the three compounds in terms of performance all year, and this meant the ultra-soft wasn’t the only strong option.

But, as the one-stop race ruled the day, we saw a fairly standard strategy from most drivers – pitting between laps 30 and 44. Proof of how durable the tyres were is in the longest stints completed. On the softs, it was 56 laps (Nico Hulkenberg), on super-softs 39 laps were managed (Stoffel Vandoorne) and a monster 44 laps (Kimi Raikkonen) were done on ultra-softs.

Blistering Pirellis

We don’t often see drivers struggling with tyre blistering on these new Pirelli tyres, but it happened quite a lot during the race in Austria. It didn’t impact performance too much, although it did mean a few drivers struggled for a brief while, but it was definitely a factor and probably concerned a few strategists on the pit wall.

Strategy uncertainty

Due to the warm and sunny conditions on Friday, teams thought the soft tyre was arguably the best performer in terms of pace and durability. It’s got a high working range, but the milder conditions the rest of the weekend suited the lower working range of the super and ultrasofts, which sparked a bit of uncertainty on which tyre to go for.

A mixed starting grid

The starting grid is usually made up of two of the three tyre compounds, but that wasn’t the case in Spielberg. All three compounds were used for the start, with a couple of drivers (the most high-profile being Lewis Hamilton) opting for super-softs and Felipe Massa opting for softs.

It was interesting to see all three being picked, and just goes to show the close performance and durability of the compounds. There wasn’t a massive amount between them, and this meant all three were more widely used during the weekend – whereas, quite often, the hardest tyre is left unloved.

Quali move for Hamilton

Knowing that Hamilton had a five-place gearbox penalty before qualifying meant Mercedes could do something different and get the British driver to set his best Q2 time on the super-soft tyre. The leading teams have such an advantage that there was no real risk of Hamilton not making it to Q3 on super-softs, and the tyres were closely matched in terms of performance.

This meant that Hamilton had slightly less performance for the first stint, but as he was racing with cars slightly slower than his own, it wasn’t an issue. He was able to go a little longer and the tyres held up enough for him to make up ground in those final laps, before a final stint on the more grippy ultra-softs which allowed him to attack Ricciardo for third in the end – he just missed out on a podium.

The Kimi train

Ferrari appeared to keep Kimi Raikkonen out longer in his first stint, giving him the lead and attempting to slow down Valtteri Bottas – who had emerged behind the Finn on fresh tyres – and allow Sebastian Vettel to catch up. But, his tyres weren’t in great shape by that point and the Iceman failed to pull off the strategy call. So, it didn’t really work.

First lap drama

The start and first lap pretty much secured the results they scored for many. Bottas got a perfect start, so good the FIA investigated him for a jump start before taking no further action, and this allowed him to establish a gap and control the pace. Behind, Daniil Kvyat smashed into Fernando Alonso and Max Verstappen, with the two drivers spinning around being forced to retire. Williams moved from the second-last row into the points due to the first lap and Jolyon Palmer also made up ground, so this was their gains came from, rather than strategy. A few drivers made up more ground than others and this meant they were able to elevate their positions without the intervention of strategy.

Late attacks

Hamilton was able to close on Ricciardo late on due to the slightly better performance of his ultra-softs and the general pace of the Mercedes. This meant it was a tense final few laps but he ended up just missing out, losing some time from a failed pass on the penultimate lap. We saw once again that the Ferrari seems to treat the softer compounds a bit better and while Vettel stopped before Bottas, his tyres seemed in better condition towards the end and the car has always gone well on super-softs. He closed the gap fairly quickly as Bottas appeared to struggle a bit, but he couldn’t get close enough to make a move and ran out of time.
