The changes that helped Mercedes fit DAS

Mercedes was the talk of Formula 1's first pre-season test, when onboard footage helped reveal the team's radical new Dual-Axis Steering System – which has become known as DAS.

The changes that helped Mercedes fit DAS

This toe-angle adjusting system has intrigued rival teams and fans alike, as they marvel at Mercedes's ingenuity whilst also hunting out answers about its operation and legality.

While some of the details of how DAS work remain hidden for now, Giorgio Piola's latest illustration of the Mercedes W11 offers us a glimpse of a few changes that the team has made at the front end of its car this year.

Rather than the drivers pushing and pulling the steering wheel, it appears that the system is activated by a button push. This action then alters the position of the wheel through use of the power-steering hydraulic system.

The two cylinders at the upper wishbones mounting point (above left illustration, red arrows) are totally new for 2020 and may provide some of the answer as to how Mercedes has incorporated DAS.

It's believed that internally these run the height of the bulkhead, and may be used as part of a larger scheme to influence the behaviour of the steering assembly too.

The steering rack is also mounted on the front face of the bulkhead and enclosed within a carbon fibre fairing, with the steering arms mounted as far forward as possible.

This places them in line with the lower arm of the wishbone for maximum aerodynamic gain as can be seen in the image below.

What needs to “change” for Red Bull is ending Verstappen’s errors

OPINION: Going up against the dominant force of Mercedes and Lewis Hamilton was always going to demand the best from Red Bull and Max Verstappen. But after making a couple more errors during the Portuguese Grand Prix, the Dutch driver showed there's a small gap he still needs to close in the 2021 Formula 1 title fight.

Red Bull's Portuguese Grand Prix fortunes were decidedly second best to Mercedes', but the result skews the potential that the team had at Portimao. With a new set of updates, the team looks good going forward into the rest of 2021's spicy F1 competition

Just as he did in 2020, Lewis Hamilton had to come from behind to win the 2021 Portuguese Grand Prix. Only this time there were two rivals he had to pass, among the several challenges he had to overcome, on his way to securing a 97th grand prix victory

The data that leaves both Red Bull, Mercedes uncertain of supremacy

Lewis Hamilton topped the crucial FP2 session on Friday as F1 returned to Portugal, but his Mercedes team cannot be sure it has the edge on its Red Bull rivals. As cool temperatures and wind combine with the still-slippery surface to present drivers with quandaries over set-up and tyre warmup, there's still everything to play for come qualifying.

How in-form Norris is staking his claim as Britain's next F1 champion

As a highly-rated Mercedes junior, George Russell is naturally billed as Lewis Hamilton's heir apparent where Britain's next Formula 1 champion is concerned.

The biggest headache F1 faces over its sprint race experiments

The news this week that F1 has green-lit 'sprint qualifying' races that will determine the grid for three grands prix in 2021 was met with a blend of excitement and scepticism. But before those in both camps can be vilified, F1 must first work out what its criteria is for success - and what will justify making them a more permanent fixture

The essential quality Tsunoda has to harness better

A rapid ascent through the junior categories meant Yuki Tsunoda's arrival in Formula 1 was always going to be much-hyped. It's not been smooth sailing for Red Bull's latest protege so far, but his confidence has never wavered - something he'll need to rely on to continue his progress into the driver he believes he can be.
