FRONT WING
Based on Williams' CFD models, profile of cockpit-adjustable flap has been improved. Endplates have been reprofiled and feature a foot on the outside.
REAR WING
Dramatic profile changes improving aerodynamics and maximum downforce, whilst new assembly of rear wing flap and main plane offers a greater range of adjustments.
SIDE CHIMNEYS
Designed by Williams through CFD simulation, side chimneys improve airflow over the rear of the car whilst also aiding cooling. They replace the louver vents of 2009.
FRONT TYRES
Avon will develop a new bespoke tyre for F2 in 2010, with improved compound and construction expected to yield significant gains. Tyre size changed to 245/600-13.
SIDE BARGEBOARDS
New bargeboards significantly increase downforce generated by the underside of the car, with minimal effect on drag.
REAR END/GEARBOX
New magnesium casings for gearbox and adaptor reduce overall weight and improve weight distribution of the car.
FUEL TANK
Fuel tank capacity has been increased and collector system improved to cater for longer race distances in 2010.
ENGINE
Upgraded Garrett turbocharger takes standard power to 425bhp, with overboost power increasing from 450bhp to 480bhp.
Further detailed information on the
significant advances made to the F2 car for the 2010
season are below:
Aerodynamics
- Aerodynamic changes have been designed by the Williams F1 team
using their CFD simulation software. Williams' CFD-based
predictions for improvements to the car have proved extremely
accurate after being corroborated during testing. Maximum downforce
generated by the car has improved by 30%, whilst aerodynamic
efficiency has increased by 24%
Front Wing
- The profile of the front wing flap has been changed to improve
under-car airflow and downforce
- The front wing end plates are completely new, and now
incorporate a foot on the outside of the plates
- All changes to the front wing have been evaluated by Williams
F1, using their F1 CFD simulation
- The front wing is cockpit-adjustable, with drivers able to
change the increment by half a degree at a time. This is a unique
feature outside Formula One
Rear Wing
- The shape of the rear wing assembly has changed dramatically
for 2010, improving aerodynamics and increasing downforce whilst
also helping to reduce overall weight
- The rear wing flap has also changed. In 2009 only the rear flap
was adjustable. This flap is now combined with the rear wing main
plane, and they can be adjusted as a pair, offering more
downforce
- A greater range of adjustments can now be made to the rear
wing, which can generate more overall downforce as a result
Side Chimneys
- The new side pod chimneys have two chief functions: to improve
the flow of air over the rear wing, and to improve cooling
- Four types of chimney were designed and trialled by Williams
using their CFD simulation
- Additionally they direct hot air coming out of the radiators
around the rear wing, reducing the amount of turbulent air flowing
across it, resulting in greater downforce and aerodynamic
efficiency
- They also help draw more air through the car, cooling the
engine, radiator and intercooler
- The side chimneys replace the 'Louvre Panel' design of
2009
Tyres
- Formula Two will use an improved compound and construction of
tyre in 2010. The compound has been specifically designed by Avon
for F2. The development process began last autumn, and will be
completed after the pre-season tests in February
- The front tyre has also changed in size, from 250/570-13 to
245/600-13
- It is anticipated that the changed tyre compounds will lead to
significant gains on track
Barge Boards
- The new barge boards significantly increase the amount of
downforce generated by the underside of the car - by implementing
these boards the car is able to produce up to 300lbs extra
downforce from the underside of the car
- Improved airflow around the 'coke' section at the back of the
car has also been a benefit to efficiency
Gearbox
- The material used to construct the adaptor (gearbox to engine)
and the gearbox main casing has changed from aluminium to
magnesium
- Operating weight reduced and overall weight distribution moved
towards the front of the car
Fuel Tank
- Both the fuel tank and fuel collector system have been revised
for 2010, predominantly to cater for the longer race distances
- The fuel tank has a larger capacity whilst the pick-up
efficiency of the collector system has been improved
Engine
- Engine power has been increased for the 2010
season
- The Garrett turbocharger used in 2009 will benefit from a
larger compressor and improved flow, leading to an increase in
standard power from 400bhp to 425bhp, and an increase in overboost
power from 450bhp to 480bhp
Detail Changes
- A host of other detail changes have also been made to the car,
including changes to the water system - to improve cooling - and
the exhaust system, to improve airflow around the underside and
rear of the car
