GP2 reverts to slicks

The 2006-spec GP2 series Dallara chassis will feature one major aerodynamic change in so far as the rear wing element will now feature a biplane wing, with the triple-plane used in 2005 only permitted for use at the Monaco round of the series. The cars will also feature reinforced front upper and lower wishbones and reinforced front and rear suspension uprights.

Brembo have developed new monobloc brake calipers and disc bells, for use exclusively in the GP2 series in 2006.

The GP2 series 4 litre Renault V8 engine, made under the supervision of Mecachrome, will feature an internal, cartographic and software upgrade, and the car will also feature a new engine air duct. These upgrades have been designed to improve performance and fuel consumption.

The 2006 GP2 series gearbox, manufactured by GearTek, will feature a new 8 position barrel, ratchet body and software alongside a new transverse shafts fixing system to enable improved gear selection.

In addition, all GP2 series cars will run on new 'slick' Bridgestone tyres, which will not feature the grooves seen in 2005. The new tyres will be supplied in soft, medium and hard compounds, with the choice being pre-determined by Bridgestone and the GP2 series before each event. The wet tyres will remain at 2005 specification.

In 2006, GP2 series sporting regulations will change to award the driver who sets the fastest lap of a race a single point, rather than the two points given in 2005. Added to this, the driver must have started from his prescribed grid position in order to claim fastest lap.
