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.

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

Williams' shorter nose and new front wing not a bolt-on improvement

By on

Williams have finally managed to get a shorter version of its car's nose ready for racing, accompanied with a new front wing. Just one item is available at the Bahrain Grand Prix, after the team rushed to manufacture one after finally succeeding the front impact crash test, following numerous failed attempts. With obvious aerodynamic benefit, F1 teams have recently been pursuing this route, with Red Bull also notably having required many crash tests before finally coming up with a s... Read more

Mercedes debuts new 'Nose 1' iteration, including S-duct

By on

As was expect, the Mercedes AMG F1 W07 was equipped with a new nose cone when it left the pits on Thursday morning at Barcelona. Named 'Nose 1' by the team, it is the follow-up of the 'Nose 0' (inset, top left) that was used in the first three days of testing, and which was essentially the same as last year's nose cone.

The new one is a clear evolution of the same Mercedes concept. Rather than switching over to a thumb style nose, the team have retained the small nose box, rounded t... Read more

Mercedes' W-floor, end of the bargeboard?

By on

Having completed more than the targeted mileage on the first day of testing, and actually topping their mileage record from any test session since the introduction of the current engine regulations, Mercedes are again one step ahead of the competition as they have already started to add new aerodynamic components on their car, a single day after the W07 debut.

Named the W-floor by Mercedes, the area ahead of the sidepod now features a number of serrated horizontal and vertical panes... Read more

Mercedes re-introduces curvy rear wing

By on

Perhaps the most obvious aerodynamic change on any F1 car at the Belgian Grand Prix was Mercedes' new rear wing, featuring a curve not seen on any current Formula One car. Rather than a fully horizontal leading and trailing edge of each of the rear wing's elements, the new wing features a curved shape that is lower in the middle, hence creating a wing that generates more downforce closer to the car's centre line.

The technique was used on several older Formula One cars, such as the ... Read more

McLaren relieved to get data on short nose

By on

Only just validated in an FIA crash test, McLaren brought its new shorter nose to the Austrian Grand Prix, with the single available item to be fitted on Fernando Alonso's car. As was publicly stated by several teams in winter testing, short noses do have their advantages, particularly due to the mandatory neutral central section of the front wing.

Red Bull Racing is the other recent example of reducing the car's nose, even though it wasn't as radical a change as McLaren did, replac... Read more

Red Bull's pride fails to bring major improvement

By on

Red Bull's Christian Horner was proud as a monkey at Barcelona, where his team finally showed up with a short nose, following 14 internal and 4 FIA tests (as reported by AMuS), until at last a design was found to match the regulatory requirements. 2 days later however, the same Horner was quoted as saying "we'll have to look at 2016", effectively writing off the 2015 campaign after another disappointing race.

As mentioned by the team, the new nose is considerably shorter, having qui... Read more

Ferrari seeks to exploit Coanda effect on sidepods

By on

Ferrari have brought a dramatic car update to Barcelona, and it appears there was hardly an exaggeration when Arrivabene claimed beforehand that 70% of the car was changed. Clearly, the team has put a lot of effort in getting this update package together, but with the changes so dramatic, Ferrari nonetheless opted for Vettel to run with the updates and Raikkonen without, getting a full race of comparison data.

On Friday, Raikkonen was still seen running Ferrari's new update packages... Read more
