Over the years, significant strides have been made to improve driver safety and reduce the risk of injury in the event of an accident. The introduction of features such as the halo cockpit protection system and increased crash safety standards have helped to make F1 cars safer than ever before. In addition to carbon fiber, other advanced materials such as titanium and magnesium are used in various components of an F1 car. These materials offer excellent strength and weight properties, making them ideal for applications where weight reduction is critical. Innovative construction techniques, such as additive manufacturing (3D printing), are also being explored to further enhance the performance and efficiency of F1 cars. The area beside the driver, at the front of the sidepods, around what we call in F1 the 'barge boards', can produce a lot of downforce.
F1 Podcast: Hulkenberg's big move - and Newey's?
Senior sources at Red Bull say the team has received no formal resignation from Newey, who holds the role of chief technical officer at the Milton Keynes-based outfit, and that they still believe there is still room for dialogue with the 65-year-old. First reported by Germany's Auto Motor und Sport on Thursday, Sky Sports understands from senior figures within the sport that Newey has informally communicated to fellow senior Red Bull colleagues his wish to cut his near two-decade ties at F1's world champion team. The result is an instantly recognizable yet understated car and one we'll likely see on the podium a lot this season. Twinned with a lighter blue in 2022, this season's McLaren is reminiscent of the wildly popular one-off livery the team ran at the 2021 Monaco Grand Prix as a tribute to long-running sponsor Gulf. Vettel, who had a penchant for naming his chassis, called his RB9 base ‘Hungry Heidi’ for the year ahead as he searched for a fourth consecutive title – and it certainly played host to moments of Formula 1 history. The final year of the previous regulation cycle saw the field largely converge for most of the year, which left the two title challengers standing above the rest on an even higher plane than the rest of the chasing pack.

For example, having the pushrod configuration at the rear can allow a narrower front-end of the gearbox and therefore improve the airflow to the diffuser. Yes, there are small implications in terms of the inboard packaging and weight but these are trivial compared to the aerodynamic implications. As Sauber technical director James Key says, the decision on pullrod or pushrod is purely for aerodynamic reasons, not mechanical ones. Haas stuck with its front pushrod and rear pullrod configurations, but of course, that could change before the car hits the track as renders often feature a different suspension configuration to the real car. But there’s another, even more important sidepod design trend where we could see some variation.

It’s also about how we use the car, how we control the car, how we evolve the balance and set-up to work with the aero package. The diffuser is also altered considerably, owing to its pairing with the revised underfloor venturi tunnels ahead. The new dimensional criteria that the designers must work with is a narrower exit of 750mm, compared with 1050mm. Also a much taller exit of 310mm is possible, compared with 175mm under the previous regulations. In a recent lecture, McLaren Chief Operating Officer Jonathan Neale estimated that an F1 car consists of 16,000 parts, of which only 10 percent are carried over year on year. Moreover, Neale argued that the car is in a permanent state of obsolescence – because by the time parts are at a race track, there’s a new generation going into production to replace them.
The materials used in F1 car design are carefully selected for their strength, lightness, and durability. Carbon fiber composites are the material of choice for many components, including the monocoque – the structural chassis of the car. This allows for a lighter and stiffer chassis, which in turn improves handling and performance. We’ve been hard at work turning our learnings into development at the start of the season. We’ve seen some encouraging first steps, leading to our first podium of the year in Australia.

The lower profile tyres also have the added benefit of reducing the sidewall deflection changes and the resulting aerodynamic wake effect that occurs. The teams spend a lot of effort on simulating the airflow regimes around the tyre shapes and interactions with the car bodywork. Reducing the sensitivity in this area will be a benefit in both the car design process and resource required – something that's particularly important in the era of the cost cap. Virtual safety cars (VSC) were introduced in 2015 following Jules Bianchi’s fatal crash during the 2014 Japanese Grand Prix, to control cars’ speeds during yellow and double yellow flags. Bianchi hit a recovery vehicle that was removing another car that had skidded off the track. One area of particular interest is the development of sustainable technologies in F1 car design.
PUSHROD vs PULLROD SUSPENSION
Some of these new engines were capable of achieving 20,000 rpm during 2006, though for the 2007 season engine development was frozen and the FIA limited all engines to 19,000 rpm to increase reliability and control at increasing engine speeds. A substantial amount of downforce is provided by using a rear diffuser which rises from the undertray at the rear axle to the actual rear of the bodywork. F1 regulations heavily limited the use of ground effect until the 2022 rule change, which are a highly efficient means of creating downforce with a small drag penalty. However, this drag is more than compensated for by the ability to corner at extremely high speed. The aerodynamics are adjusted for each track; with a low drag configuration for tracks where high speed is more important like Autodromo Nazionale Monza, and a high traction configuration for tracks where cornering is more important, like the Circuit de Monaco.

By the time that the M19C came along in 1972, suspension design had already become more complicated. McLaren's 1969 contender - the M7C - had incredibly basic suspension with just a spring damper connecting the wishbones and little wiggle room to adjust the set-up for different conditions. The lower wishbone is usually very high so that the two wishbones are very close to better direct the airflow to the rest of the car. Tyres also act as part of the car's suspension and have to be considered when designing the car.
Key design trends of the 2023 Formula 1 cars
If it weren't for the different shape of the 2022 car, you'd be hard-pressed to tell the difference between this car and Max Verstappen's 2021 title-winning steed. In fact, P4 in Germany was the only time Vettel finished off the podium all season when he did end a race. Williams, and Mansell in particular, would regularly hold gaps upwards of a second per lap on the next-fastest car behind in qualifying and race trim, sometimes higher. His finishes of P8 and P9 in Australia and Malaysia had him on the back foot and, despite a stunning second half of the year – including a famous win at Suzuka having started 14th on the grid – Alonso took the title with races to spare.
This hybrid system not only improves fuel efficiency but also provides an additional boost of power. In this way, Ferrari's philosophy could not only give them problems balancing the car front to rear as the season progresses, but also limit the amount of total downforce it can create. This might mean they are generating less downforce at the front of their floor, but it gives them lots of potential to create plenty of downforce at the rear with the diffuser.
Adrian Newey has earned a roll of honour in Formula 1 like no other individual across the decades, designing cars to win titles throughout eras. The first is that the reduced tendency to stall might produce a car that is more predictable to drive. One advantage of reducing the download at the tips of the wing - what we call 'backing-out' the tips - is that airflow structures generated there will be much less stressed.
If you neglect the back of the car, then the rear wheels will slide and the driver will soon find himself pointing in the wrong direction. Returning to the rear of the car, it's also worth noting that the rear wing will sit higher, as we edge back towards the height of the wings used between 2009 and 2016 (950mm). “I think the idea of the major upgrade has become a bit of a myth,” says Chester.

Although the front wing has to create downforce of its own, it also has to work the airflow around the front tyres to reduce the amount of wake left behind it. Article 3.9.8 of the technical regulations has been modified and Ferrari has meticulously studied it to adopt an improved version of what Mercedes tried. The gain in terms of aerodynamic performance is not particularly significant, as the Ferrari engineers themselves admitted, however, it does help in finding the outwash effect of the front tyre to reduce drag. Many, many things are new on the 2022 car – but the power unit is not one of them, with Formula 1 set to retain the current 1.6-litre turbo-hybrid units. This is no bad thing, given that they’re already the most advanced and most efficient engines on the planet. The effect of the "catastrophic downforce loss" – to quote an engineer centrally involved with the project – resulting from the ‘dirty air’ being churned chaotically off a leading car currently.
This could be because they need to make up the front downforce which their front wing can't create. The key with this, though, is that you want to keep as much energy in the air as possible, so as it travels down the car you can use that energy in the diffuser, at the back of the car. Looking at the performance of cars from testing - always a fool's errand but bear with me - you might conclude that the Ferrari-style front wing is doing the better job. For this reason, quite often, a more predictable car with more consistent downforce but slightly less maximum load will end up being quicker than a car that in theory has more downforce but that which cannot generate the maximum load consistently.
For 2019 the front wings were widened to two metres wide and a tightening of regulations meant that designers had to be much more restrained in their ideas compared to the previous few years. A well-designed front wing will improve the all-round performance of a car - but if a team gets it wrong, it will have to try to recover the damage and compensate with the rest of the car. In this quest for speed an F1 team's factory never stands still, working year-round to improve every part of the car from the front wing to the diffuser, coming up with increasingly complex designs to find that edge.
