Ferrari's new Spanish rear wing assembly

By on

In an attempt to resolve its unstable rear end, Ferrari introduced a new rear wing assembly in the Spanish Grand Prix, following comparison tests during Friday's FP1 with the older twin pillar layout. On Saturday, both cars featured the displayed single pillar rear wing, a design including a curve around the exhaust pipe and a single, central pillar to provide support to the rear wing.

Ferrari previously ran two pillars with fairly long chords connecting to the bottom of the rear wi... Read more

McLaren brings new diffuser to Spain

By on

McLaren have fitted a brand new rear diffuser to its two MP4-29's, featuring more rounded profiles on each outer extremity, following an aerodynamic trend that was started by Red Bull Racing during the winter tests. Along the rounded edges is an additional winglet that previously used to be only as wide as the horizontal upper edge of the diffuser. The change will particularly help air extraction at each side of the diffuser, allowing for more expansion into the wake of the rear tyr... Read more

Sauber sheds weight with major car upgrade

By on

Among the many updates, Sauber have probably introduced the most comprehensive upgrade package of the entire field in Spain with a long awaited upgrade that is set to get the car down to the minimum weight limit. Word has it that the team's update reduces the car's entire weight by around 15kg, making sure that with Gutierrez behind the wheel, the car is now no longer overweight. For Adrian Sutil however that is still far from the case as the German is approximately 10kg heavier tha... Read more

Ferrari revives the blown wheelnut

By on

Ferrari have revived the blown wheelnut system by racing it at today's Chinese Grand Prix. Tried at the two day Bahrain test 2 weeks ahead of the Chinese race, the team found its system to be beneficial in managing front tyre wake.

Part of the system are much larger brake inlet scoops, fetching air flowing over the front wing. This is then directed through the wheel hub and exited via new open wheel nuts on the outside of the wheel. This means air is pushed from a high pressure area... Read more

Mercedes debuts new, higher nose

By on

Mercedes AMG have finally introduced their bespoke new nose cone for its F1 W05. Initially scheduled for introduction at the Australian Grand Prix, the nose cone design had to be adapted repeatedly and failed the FIA crash test three times before passing the front impact test.

The team mentioned their new nose would make it easier to balance the car, admitting that the one raced so far was just a simple version while this development was ongoing. Sharing obvious similarities, the ne... Read more

Red Bull debuts new drag cutting rear wing endplate

By on

Among the many updates present on various cars at Melbourne, Red Bull certainly has one of the more interesting as the RB10 features a brand new rear wing endplate, including a new solution to reduce the drag induced by the rear wing.

The previously common solution, as seen on the inset, was to add gills on the high pressure side of the rear wing. These gills allowed some air to bleed off from the high pressure area in between the endplates to end up on the outer sides of the endpla... Read more

Williams adopts central cooling funnel

By on

Williams have enjoyed several extremely productive testing days so far, and with the end of the tests nearing, the team is applying and testing new aerodynamic parts. One of the bigger upgrades fitted on the FW36 on Thursday with Bottas and Friday with Massa is the new rear bodywork featuring wider sidepod exits and a central funnel that blows hot sidepod air around the exhaust.

The team switched bodywork throughout the day for both drivers to be able to evaluate the new parts prope... Read more

Did Mercedes take a close look at the RB10?

By on

Having enjoyed a reliable test Jerez, Mercedes have begun varying aerodynamic parts and verify performance, rather than only reliability. Mercedes appear to have had a very close look at Red Bull's rear end packaging during its few outings at Jerez as the team have introduced new bodywork around the exhaust.

Until noon, the F1 W05 was seen with the same spec as in Jerez, with narrow bodywork around the central exhaust and large oval cooling outlets on each side of the gearbox. The n... Read more

A closer look at McLaren's butterfly suspension

By on

McLaren have come up with the first real innovation of the year by creating rear suspension wishbones that are very different to what we usually see. It is the normal approach to have a horizontal teardrop design, almost parallel to the reference plane in order to minimize drag created by the suspension elements. McLaren's version though as just a bit different.

The team's approach is far away from drag reduction. Instead, the elements are rather big with a cross section similar to ... Read more

New Ferrari sidepod panel makes it to race day

By on

Scuderia Ferrari have introduced another part to their F138, namely a new sidepod panel with a small bridge bending over the sidepod shoulder. The item was previously tested during free practice sessions, but before the Brazilian Grand Prix weekend never made it past Friday evening. At Autodromo Carlos Pace however, both cars had the new element fitted during qualifying, hence they will also be used during tomorrow's Grand Prix.

The item is designed to better control airflow over t... Read more
