Shark fins and T-wings to be banned on safety grounds?

By on

Following the launch of the first few cars in launch week, voices were raised that shark fins, engine cover sails, or whatever they would need to be called, should be banned from Formula One. F1 teams themselves didn't agree however, as Red Bull's attempts to get them banned last summer failed, most likely because some teams were already happily exploring the aerodynamic possibilities of such engine cover extensions.

Now, with testing underway, and literally every car underway with ... Read more

F1 2017 explained: Power unit changes

By on

Following up on their videos on regulation changes, Mercedes have now highlighted the impact of these changes on the power unit.

In essence, it comes down to coping with the difficulty of having more full throttle each and every lap, while having to work against the increased drag that comes with the additional downforce. The increased stresses that will be put on the engine have resulted in a slightly heaver power unit for Mercedes, whereas the cooling requirement have also gone up... Read more

F1 2017 explained: Key changes

By on

The regulation changes for 2017 are quite extensive, to such a measure that many designers have said it's their biggest change they have had to cope with in their careers. Lots of details have changed, but there are a number of highly impacting changes, aimed primarily at increasing downforce and enhance the way a Formula One car looks.

The front wing for instance will feature a swept forward shape while also being wider by 7.5cm each side. The latter provides additional downforce, ... Read more

Blown wheel hubs continue to be tricky business

By on

Blown wheel hubs have been adopted by a large number of teams this season, but the feature continues to keep aerodynamicists busy.

At Monza for instance, Red Bull Racing briefly tested an alternative to the open wheel hubs by putting a conical cap inside each front wheel's axle. The cap did appear to have small apertures to still allow some airflow to get through, but clearly much less than what would otherwise be possible. Both cars however were running the usual open hubs in quali... Read more

Haas revives double-waved rear wing at Monza

By on

The Haas F1 Team drew a lot of attention with its new double-waved, M-like rear wing, a completely unique shape for a modern rear wing in Formula One. It's rare these days to see a rear wing that has a different shape along its entire span, and hardly a surprise that Mercedes have, or at least had the most varying profile with its spoon rear wing, as the ones used at Monza and Spa-Francorchamps. Apart from the need to test it under yaw, such designs are furthermore made difficult by... Read more

Sauber making strides with new aero package

By on

Sauber have at long last introduced an upgrade package for its low key C35. With the team's future secured, money has become available to produce what had been designed in the first half of the season, allowing the team to recover some of the deficit that it had built up since the beginning of winter testing. The team's new package is indeed extensive, with a new, shorter nose much along the lines of what other have been been doing last year. The front wing supports feature a curve ... Read more

Ferrari tweaks front wing

By on

While Mercedes introduced fairly extensive updates on their car's rear wing endplates and barge boards, Ferrari had some upgrades that focused mostly on the front of the car. Apart from a pair of small winglets behind the front suspension, the front wing was modified to further improve airflow control ahead of the front wheels.

Following the trend of pushing as much air as possible outboard of the front wheels, the front wing endplates were modified to feature a curved trailing edg... Read more

McLaren opts against racing new rear wing endplates

By on

McLaren have turned up at Austria with a dramatically different rear wing end plate than the previous versions, including three new long vertical slits. These are positioned downstream of the two slits that were already present along the leading edge of the end plates.

All vanes are aimed at directing airflow inboard, hence allowing air to stream into the low pressure area that is induced underneath and behind the rear wing's downforce generating elements. The resulting reduced pres... Read more

What Williams was really doing with its illegal rear wing

By on

The Williams team surprised during this week's Barcelona in-season test by coming up with a very special rear wing. The wing, featuring an additional section ahead and above the usual rear wing flaps would be illegal to run in races this year, but it proved to be useful for the team in an attempt to find and remedy some of the weaknesses of this year's FW38. It was run for half a day by Alex Lynn, before Felipe Massa had it fitted on the car the entire second day of testing.

Contrar... Read more

New front wing main item of aero upgrade of VJM09

By on

Like many other teams, Force India have introduced a major aerodynamic upgrade to their car, the VJM09. Even though the update was earlier announced to make the car look quite different, in essence it's detail changes, which nonetheless could have a large effect on the car's aerodynamic properties.

The car's new front wing, immediately fitted on both cars, is the most important item of the package and features an arc on the inside of the outer footplate, a design element seen on the... Read more
