Slightly shorter than the F2008, the F60 cleverly exploits every blind spot in the bodywork rules to recoup the 50% loss in downforce from its smaller wings and diffuser...
Ferrari have a simple initial wing design, supplemented by small cascade wings elements fitted to the end plate (the new rules do not allow bridge wings). The endplates themselves now aim to sweep around the outside of the front tyre: to aid this a small fence has been added to the footplate.
Inside the end plate is the mechanism that will allow the front wing flap to adjust up and down once per lap under the drivers control. There will be no 'nose hole' this year as the new rules preclude it.
Despite the aim of the Overtaking Working Group's derived rules to ban bargeboards, there are a three spots where Ferrari have found space. Two small vanes have been added below the chassis near the lower front wishbone mounts. These are followed by a larger vane low down just ahead of the sidepod.
The sidepod fronts are the main area of aerodynamic freedom, as they are described in the rules as the area for side impact protection and thus excluded from the limitations placed on the three volumes making up the rearward part of the sidepod. To exploit this, Ferrari have shortened the sidepod front as much as possible to allow more vanes to be added.
As this area still needs to contain the side impact protection, a curious extension to the upper front of the sidepod has been added. Nick Tombazis said this was for aerodynamic reasons rather than for a side impact structure.
The rearward bargeboard encroaches into this area and a pod wing rises up from the floor to also form the rear view mirror housing. Further back along the sidepod, the F60 makes the most of the openings allowed under the rules for cooling. Both the exhaust outlet area is maximised as well as the opening, supposedly for suspension to pass through.
The nose is long and its underside features a scalloped shape, akin to Renault's R28, which should work to reduce pressure and increase downforce under the nose cone.
Already debuted in testing, the front wing is a more complex affair than seen elsewhere so far, with a two-element flap...only the upper element of the flap moves as allowed under the adjustable front wing rule for 2009: this is controlled by a switch on the steering wheel...
it's the sidepods that are the biggest divergence from designs seen so far. McLaren have chosen the keep the sidepods tall and slim: this maximises the space between the rear wheels and, in order to allow sufficient cooling area, the exit to the bottle zone curves outwards at floor level. The exhaust outlets are a distinctive feature, being placed high and far back.
At this stage the removeable panels do not feature any hot air outlets, but the lack of any other exits suggests this might change when the car starts testing in warmer climes. Aiding the airflow out of the back of the sidepod and improving flow over the diffuser the gearbox fairing converges into a sharp "V" shape at the rear of the car.
Toyota have gone for a slim nose but, unlike Ferrari, they have kept the nose shorter and raised the tip up as far as possible. This shape does provide more space under the nose cone for turning vanes, which is an area outside of the exclusion zones for bodywork. Thus Toyota have fitted a pair of vanes to the rear of the nose cone that lead back under the chassis.
The front wing is split abruptly between the FIA-mandated middle section and the downforce-producing outer spans, which feature single element moving flaps.
Most noticeable are the shapely endplates without curved leading edges to tease airflow around the front wheels; these are most noticeable when viewed from above. ...
As one of the last teams to adopt undercut sidepods, the new sidepod fronts are exceptionally undercut. They then sweep into a tight coke bottle shape before exiting in a bulbous shape over the gearbox. The only cooling outlets allowed in the engine cover also need to route the exhaust pipes; Toyota have chosen to sink the pipes beneath the engine cover rather than expose them as per the Ferrari
