The F2 Car
F2 chassis
The Williams JPH1B F2 car was designed by the Williams F1 team and
features ground effect aerodynamics and a sophisticated composite
survival cell complying with the 2005 F1 safety regulations. The
car has been significantly upgraded from its predecessor, the JPH1,
after extensive revisions carried out by both MotorSport Vision and
Williams during the winter break.
Among the host of upgrades implemented over the winter, the 2010
Williams JPH1B benefits from a package of aerodynamic revisions
following an extensive CFD evaluation programme. As a consequence
maximum downforce has increased by 30% and aerodynamic efficiency
has increased by 24%.
The new aerodynamic package also includes revised front and rear
wing profiles, providing F2 drivers and engineers with a broader
range of downforce levels to work with - facilitating greater set
up optimisation across the nine circuits F2 will visit in 2010.

All F2 cars will include standard components that will be
identical within specified tolerances and all F2 cars will be of
identical weight +/- 2kg and ballasted to a standard Driver weight
of 80kg (including all race wear and Driver safety
equipment).
Tyre size has been increased in diameter at the front to
increase grip and a new softer compound will be used. Revised
differential components will improve stability on turn-in and
mid-corner, with Avon expected to finalise their new bespoke F2
tyre in February.
The transmission is a six speed Hewland unit with pneumatically
operated paddle shift.
F2 engine
Engine power has also been increased for the 2010 season, with F2
utilising a new high flow Garrett turbocharger to raise standard
power from 400bhp to 425bhp. The new turbocharger produces an even
greater gain on overboost, with power increasing from 450bhp to
480bhp.
The engines on all cars will have identical power within 1.5% of
the target. The overboost facility is actuated by a steering
wheel button which increases maximum power by 55bhp.
Maintaining engine parity within a very close tolerance that
will make no significant difference to the cars' performance
throughout the season is one of the most important criteria of the
championship.
