McLaren introduces shapely new front wing

By on

As part of a fairly large aerodynamic update for its MP4-29, McLaren have introduce a long overdue front wing update, getting rid of the rather bulky previous design that looked dated in comparison to items seen on front running cars.

The new front wing only appears to have the leading edge of the base plane and parts of the endplates in common with its predecessor, but other than that everything is new. Still a three-element wing, the insides of the flaps have considerably changed,... Read more

Force India tweaks front wing design

By on

Sahara Force India have introduced a considerably aerodynamic upgrade for its VJM07 at Austria, including several front wing tweaks. As indicated in the image comparison, the front wing endplates now have one additional separate turning vane in an attempt to get more airflow outboard of the front wheels. The underside of the endplates have also slightly changed, dropping an edgy curve in favour or a nicely rounded profile.

Interestingly, the team have also opted to move the attachme... Read more

Ferrari trial revised bodywork

By on

Ferrari have introduced a considerable upgrade package for their F14 T in Montreal, including a new floor and this more apparent new bodywork. Fernando Alonso was seen on track with the new bodywork layout while at the same time Kimi Raikkonen ran with the older configuration, allowing the team to do immediate comparisons in the pitlane and back in Maranello.

The update includes the removal of the air outlet around the exhaust, allowing for sleeker upper bodywork. The tradeoff are s... Read more

Red Bull follows FIA request to adapt camera mountings

By on

Red Bull Racing have finally had to abandon their camera mounts inside the nose cone after the FIA requested a modification. It appears that FOM was not all that happy about Red Bull's layout, making it impossible to have a sideways or rear facing camera within the mounting. After the front facing view was found insufficient as well, Red Bull already made a modification to the camera aperture in Spain, but have now had to abandon the layout.

Instead, the RB10 now features "tradition... Read more

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
