Mercedes surprises with innovative Dual Axis Steering system

By on

Onboard images from the first day of testing at Barcelona have revealed that Mercedes' new W11 features a steering wheel assembly that moves forward and backward - apart from the obvious rotational movement to steer into corners.

The recording, coming from an onboard shot of F1TV, shows how Lewis Hamilton's steering wheel moves towards him when coming on a straight, and forward again when nearing a corner.

As Mercedes have meanwhile confirmed this is an additional way for the driver... Read more

Alfa adds fins around S-duct

By on

The Alfa Romeo team have fitted their C38 with a set of additional fins on the upper edges of the monocoque. Attached to the panel that covers the upper front suspension elements, there are 4 vertical fins on the left and right sides of the S-duct exit.

Just like the fins that Mercedes added, they direct airflow outboard, helping extraction of air out of the S-duct.

The image also reveals how the panel isn't really a great fit onto the monocoque, and even worse so against the nose c... Read more

New sidepod shape part of Melbourne package for W10

By on

Mercedes have drawn most of the attention to them at today's testing, thanks to having an upgrade package "that leaves not a single aerodynamic element unchanged".

Indeed, the updates are extensive, and reaching a lot further than the nose and front wing changes we mentioned earlier on.

Perhaps the most obvious change are the sidepods, which are a step away from Mercedes' traditional sidepod design. In fact, the new shape seems highly influenced by a design trait of recent Adrian Ne... Read more

Mercedes introduce new nose and front wing

By on

Mercedes have kicked off the second week of testing at Circuit de Catalunya, Barcelona by adding a new front end to their W10. Having struggled with front end grip during the first 4 days of testing, the upgrades will come as a welcome addition to Lewis Hamilton and Valtteri Bottas.

As another evolutionary step in Mercedes unique thin nose cone, the team have further narrowed the nose and added some sculpting to improve airflow underneath and over the nose cape that managed airflow ... Read more

Mercedes W10 rear wing airflow explained with flow-viz

By on

Testing usually sees teams apply flowviz paint on their cars to visualize airflow on certain car elements. They do so to verify the findings from the windtunnel and detect any unwanted effect that was not simulated.

So did Mercedes, revealing airflow on the suction surface of the rear wing and its endplates (flows D and E).

It is clear in the image that airflow has drawn straight lines onto the suction surface of the main flap. This shows perfect laminar flow, as one would expect w... Read more

Getting downforce through the rear wing endplate

By on

Renault F1 have arrived at Barcelona with an interesting update on their car, one that was photoshopped away from its launch renderings.

It may appear like a no-brainer, but Renault has become the first team to generate proper downforce through vanes on the rear wing endplates. While other teams limit themselves to vertical vanes that help clean up the flow or inject some more airflow underneath the rear wing, Renault have taken a different approach.

Still going on with the aerodyna... Read more

Ferrari trial halo-mounted mirrors

By on

Ferrari showed up at Barcelona with new wing mirror supports. Instead of the attachment to the chassis shoulders, the wing mirrors are linked to the halo. The team have meanwhile also added a winglet just above the mirror housing, perfectly shading the mirror itself when looking at the car from above.

It was only between the Chinese and Azerbaijan Grand Prix that the FIA announced that mirrors could also be attached to the halo. The Technical Directive was a response to the decreasi... Read more

McLaren surprises with unique nose cone

By on

McLaren didn't disappoint with their much anticipated aerodynamic update to the Renault-powered MCL33. With updates all around the car, the most intriguing changes were done at the front, where an entirely new and unique nose cone has debuted on the car when it was sent to scrutineering on Thursday afternoon.

McLaren was clearly inspired by solutions seen elsewhere, with the team now implementing an open thumb nose, akin to Red Bull Racing's solution to reduce drag created by the ti... Read more

How Ferrari's vented rear view mirrors really work

By on

A lot has been said about Ferrari's innovative wing mirrors. Changes like this are hard to come by these days in Formula One, but Ferrari have certainly thought out of the box here. While all other teams have their mirror housings as round as possible, to limit drag created by them, Ferrari's items feature a small gap all around the actual mirror. The traditional mirrors guide all air around the housing, whereas with Ferrari's new design, some airflow flows through the housing.

Red Bull sort out bargeboard panels

By on

In what continues to be a crucial area of aerodynamic development, Red Bull Racing turned up in Australia with an improved version of their barge board panels, which make up for a quite complicated set-up, even this early in the season. Thanks to the stable regulations, teams are happily continuing the development paths of last year, even though further downstream, Red Bull's high sidepod inlets are a big change compared to their 2017 RB13.

Still, the barge boards were complex at th... Read more
