The Williams JPH1B

For 2012, the Williams designed JPH1B F2 car has been given a number of significant upgrades in order to enhance performance, reliability and overtaking.

These developments will mean the 2012-spec car will be able to lap around two seconds faster than the previous F2 machine.

F2's expert engineers spent the majority of 2011 conducting extensive testing, assisted by reigning champion Mirko Bortolotti, to develop the F2 car including switching from Avon to Yokohama tyres as well as new carbon composite brakes. Such new features have led to increased grip, handling and stopping power and saw the car lap a full 2.363s quicker than the next fastest driver during post-season testing at Barcelona.

In 2010, the F2 car also underwent an extensive upgrade package with performance developments made throughout. Engine power was increased utilising a new high flow Garret turbocharger to raise standard power from 420bhp to 425bhp. The new turbocharger also provides drivers with an even greater gain on overboost, with power increasing from 480bhp to 500bhp.

The car's aerodynamics were also enhanced improving efficiency by 15% and generating 20% more downforce. Meanwhile, the operating weight of the Williams JPH1B was reduced by around 25kg following the introducing of new castings for the gearbox and bell housing adaptor in magnesium, rather than the previous aluminium, as well as many detail upgrades. Weight distribution was also favourably improved by these changes.

Aspects of equality and reliability of course remain of utmost importance to the F2 series and from a total of 352 race starts there have only been five car failures, a remarkable rate of just 1.4%.
