Some fractions of the F1 paddock have raised doubts about the 2026 regulations and its impact on racing. But the FIA and F1 chiefs are confident about their plans, having employed CFD technology that offers supercomputer-like performance Analysis:
Formula 1’s plans for a radical shift in car and engine rules for 2026 has prompted a fair deal of intrigue in recent weeks.The planned increase in electrification, with a 50/50 power split from the battery and combustion engine, has prompted concerns about drivers running out of energy on the straights and needing to change down gears to recharge.
“The performance profile of a 2026 car in simulation now doesn't look terribly different to 2023,” he said. “So it really became quite transformational as we teamed up with AWS. We had to learn together, it wasn't a case of here's a bit of software, you load it and run it. We had to do an awful lot of work to get it working properly. But it did give us this ability to run these incredibly complex models.
As Dr Neil Ashton, Principal CFD Specialist Solution Architect at AWS, explained: “To transform the sport for what was originally 2021, but eventually became 2022, they created this small team . Before AWS got involved, a single run for F1 was taking around 60 hours. Now, that’s down to 10 hours. But it’s even better than that. Dr Ashton adds: “That’s a pretty big jump, but it is also a matter of how many they can do simultaneously. They can do 10 of them at once if they wanted to, so it’s not just one job being faster. It’s the ability to submit many different jobs at once.”
“So because they were looking at it from 10, 20, 30 and 40 meters behind the car, it really was a big simulation. And to add to that, they also wanted to look at cornering. “And, without a shadow of a doubt, I think if they hadn't had the AWS resources, I think they really would have struggled to run such a big model.
“We knew that that would develop very quickly. And actually, they developed quicker than we anticipated. “The one thing we're absolutely certain on, and this is from driver feedback and the data that we see, is that with the 2021 cars, when they were following not only had they lost an enormous amount of downforce, but they were very, very unpredictable.
“The important thing in developing the 2022 car from an aerodynamic point of view was to understand what was important for the following characteristics and make sure that those things weren't destroyed.
