Mercedes brings F1 sidepod aero update to Suzuka to catch Ferrari

Mercedes has made minor tweaks to its sidepod-mounted turning vanes ahead of the Japanese Grand Prix in an effort to close back in on Formula 1 rival Ferrari

Mercedes brings F1 sidepod aero update to Suzuka to catch Ferrari

Following the summer break and the introduction of its successful Singapore upgrade package, Ferrari has largely outclassed Mercedes, which has not brought any meaningful updates in recent rounds.

Aiming to draw level once more, Mercedes has brought a small update to Suzuka to put the pressure back on Ferrari.

Team principal Toto Wolff promised that Mercedes would test "little things that we are just interested to explore" in Suzuka, but stressed that the team has no plans for any larger upgrades this year.

The turning vanes have now transitioned into three distinct 'phases'.

The front vertical piece (green arrow) remains, but the central horizontal elements marked with the red arrow have increased from four to five, and no longer extend below the sidepod-mounted element as the previous specification did.

While the sidepod-mounted piece (purple arrow) was formerly made of one piece, it has now been broken into two parts - presumably with the intention to generate tip vortices.

The image below details the difference between the old specification (left) and the new specification (right).

The element mounted to the top of the sidepod will induce a small amount of lift, but in doing so can direct a passage of air down the slope of the sidepods.

Breaking the two parts up allows the team to extend the vertical component further up.

Over the season, Mercedes has been conscientiously modifying its turning vane and bargeboard assembly to extract performance from the car.

At the beginning of the year, the launch car featured three vertical vanes, but the switch to a greater focus on the horizontal elements suggests a vastly modified approach to conditioning the tyre wake.

Using a mixture of horizontal and vertical parts gives Mercedes's aerodynamicists more options in breaking down the turbulence and turning it into something useable.

For the second race in a row, Mercedes has ended the first day of track action on top. It’s in a commanding position at the Russian Grand Prix once again – this time largely thanks to Max Verstappen’s upcoming engine-change grid penalty.

OPINION: With its days apparently numbered, the MGU-H looks set to be dropped from Formula 1’s future engine rules in order to entice new manufacturers in. While it may appear a change of direction, the benefits for teams and fans could make the decision a worthwhile call

But as MARK GALLAGHER recalls, while Schumacher wowed the world with a car that was eminently capable, Hakkinen was fighting to make his mark with a famous team in terminal decline
