GP2 Series Cars
The GP2 Series car is used by all of the teams, and features a Dallara chassis powered by a V8 Renault engine and Pirelli tyres.
- Chassis
- The 2009 specification GP2 Car has been designed by Dallara Automobili. The 2006 GP2 car featured a biplane rear wing, with the triplane rear wing used in previous seasons only to be used at the Monaco race. The front upper and lower wishbones have been reinforced, as have the front and rear suspension uprights.
- Engine
- The 4 litre Renault V8 engine features internal, cartographic and software upgrades designed to improve performance and fuel consumption. The engine produces 612 hp and 500Nm torque @ 8000 rpm. GP2 Series engines are rev-limited to 10,000 rpm and need a rebuild after 4000 to 4500 km. The valve train is a dual overhead camshaft configuration with four valves per cylinder. The crankshaft is made of alloy steel, with five main bearing caps. The pistons are forged aluminum alloy, while the connecting rods are machined alloy steel. The electronic engine management system is supplied by Magneti Marelli, firing a CDI ignition system. The engine lubrication is an Elf Aquitaine dry sump type, cooled by a single water pump.
- Gearbox
- The 2009 gearbox has been manufactured by GearTek and features an 8-position barrel with ratchet body and software upgrades as well as a new transverse shafts fixing system designed to facilitate improved gear selection.
- Tyres
- Similar to the 2011 change for Formula 1, Pirelli is now the sole tyre supplier for the series. The GP2 series runs the same compounds as F1.
- Other parts
- Brembo is supplying monobloc brake calipers and disc bells, which are exclusive to GP2.
The car also features internal cooling upgrades, a new water radiator, radiator duct, oil/water heat exchanger, modified oil degazer, new oil and water pipes and new heat exchanger fixing brackets.
- Performance
- According to research and pre-season stability tests, the 2005 model can go 0 to 200 km/h (124 mph) in 6.7 seconds. The car has a top speed of 320 km/h (198 mph) meaning that it is the fastest single seater racing car behind Formula One and Indy cars.
The 2011 model can go 0 to 200 km/h (124 mph) in 6.6 seconds. The car has a top speed of 332 km/h (206 mph) with the Monza aero configuration.

Famous quotes containing the words series and/or cars:
“Life ... is not simply a series of exciting new ventures. The future is not always a whole new ball game. There tends to be unfinished business. One trails all sorts of things around with one, things that simply won’t be got rid of.”
—Anita Brookner (b. 1928)
“I think that cars today are almost the exact equivalent of the great Gothic cathedrals: I mean the supreme creation of an era, conceived with passion by unknown artists, and consumed in image if not in usage by a whole population which appropriates them as a purely magical object.”
—Roland Barthes (1915–1980)
