Aerodynamics
  • The front and rear wings appear to be accurate in general layout
  • The front wing does not feature the inclined under fence used on the test car
  • The front wing endplates are not the ones commonly used on the test car, probably down to the artist rather than these being a new format
  • The bargeboards seems to accurate, curving under the chassis and the shadow plate running along the bottom
  • The splitter\shadow plate is about right, the section that forms the tight curve between the plate and monocoque is a detachable panel on the test car, to allow rapid changes of design
  • The sidepods, cockpit shaping and engine cover are about accurate but the “cut away” effect of the drawings obliterates the detail
  • The shape of the rear diffuser, impact structure and lower wing mount are all over simplified.

 

 

Front suspension
  • Common format pushrod and vertically inclined dampers,
  • The upper wishbones appear to mount to the monocoque with blade type flexures the outboard appears to use a spherical bearing.
  • The inside of the front of the monocoque uses three bulkhead to mount the torsion bars, linkages and wishbones

·        This shot does show how far back the pedals now are and how much room is left for damper and suspension linkages

·        No torsion bars are pictured, the common practice is for them to extend forward to protrude form the front bulkhead (visible when the nose is removed)

·        No steering rack is pictured, the collapsible steering column is horizontal and runs along the top of the monocoque, to clear the regulatory space inside the footwell

·        We already know the steering rack is placed mid way between the upper\lower wishbones, so the method of dropping the column to meet the rack still not clear

·        The steering link between the rack and upright is not shown either….?

·        Also not detailed are the bell cranks operating the dampers from the pushrod

·        Not clear but visible in a basic form is a third damper between the bellcranks,

·        Another linkage is shown above this damper which may be the antiroll bar

·        The brake discs, and hubs are inaccurately and simply drawn, however the position of the calliper could be deemed to be accurate

 

 

 

Sidepods

·        The two coolers are visible in the sidepod, they are arranged in a unusual right angled “v” format. (this has proven either be incorrect or the layout as been reived since this image was created. See:Toyota Cooling System)

·        Which cooler feeds the water system and which the oil system is not clear, the larger outer one could be presumed to be the water radiator

·        The Coolers are fed by the same duct

·        The duct is simply and drawn and brief TV footage shows the ducts are simple carbon mouldings

·        The split in the inlet does not appear to extend into the duct, but perhaps acts to direct the flow into the duct equally between the two coolers

·        The coolers and exhausts come very close to the sidepods wall, the section of sidepod below the flip up is now a large removable panel and replacement panels incorporate, outlet ducts and louvered vents.

  • Again from TV footage the car does feature a large spar extending form the monocoque to form the side impact protection, this is not shown here

 

Engine transmission installation

 

·        The exhaust system is simply drawn and does not appear to reflect the actual installation known to be on the car.

·        The engine looks to be a convention V10 and not with a radical “V” angle as per Renaults 2001 V10

·        The airbox again is simply drawn and does not do the actual component justice

·        The gearbox\transmission casing appears heavily ribbed, this design practice has been dropped in F1 since the late 80’s and may be more down to artistic license than the actual component.

·        The gearbox casting ends after the differential and then has the rear impact structure bolted to it

 

 

Rear Suspension

 

·        Again the suspension component are simplified but the general arrangement is common F1 practice

·        The top wishbone mounts high, the forward leg is above the gearbox and passes through the engine cover and run exposed to the airflow over the sidepods top to the upright.

·        The rear leg of the upper wishbone passes inside the sidepod

·        The lower wishbone still appears to pass through the diffuser, this was clear on some other images of the car, this design is detrimental to airflow through the diffuser

·        The toe link is mounted behind the drive shaft and no aerodynamic fairing has been disclosed here

·        Not clear but there appears to be a vertical damper running down the side of the gearbox

·        The bellcrank operated by the pushrod pivots transversely, the pivot is formed by the horizontal torsion bar

·        Again a third damper appears between the bellcranks

·        No clear view of the antiroll bar is shown, it appears to be behind the third damper

·        The brakes and uprights are over simplified and only the calliper position can be assumed to be accurate

·        The offset of the rear wheels is known not to be very deep and this is not apparent in the image
