Editing GP2 Series (section)

==Car specifications==
{{Unreferenced section|date=January 2023}}
The GP2 Series car was used by all of the teams, and features a [[Dallara]] [[carbon-fiber]] monocoque chassis powered by a [[Mecachrome]] [[normally-aspirated]] [[fuel injection|fuel-inject]]ed [[V8 engine|V8]] engine and [[Pirelli]] dry slick and rain treaded tyres. Overall weight is 688&nbsp;kg including driver.

===Chassis===
The 2011 specification GP2 Series car was 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. The [[Dallara GP2/11]] were the obsolete chassis since the debut in 2011 and would be used until end of 2017 season. The price of Dallara GP2/11 FIA Formula 2 Championship cars are approximately up to €1.5 million-€2 million per car (including wheels, tyres, wings, steering wheel and other components excluding engine).{{citation needed|date=December 2022}}

===Engine===
The 4.0-litre [[naturally-aspirated]] [[fuel-injection|electronic indirect fuel-inject]]ed [[Mecachrome]] [[V8 engine]] features internal, cartographic and software upgrades designed to improve performance and fuel consumption. The engine produces 612&nbsp;hp and 500 Nm (380&nbsp;ft-lb) of torque @ 8500 rpm.<ref>{{Cite web|url=https://spicerparts.com/calculators/horsepower-torque-calculator|title = Spicer Horsepower and Torque Calculator}}</ref> FIA Formula 2 Championship Series engines are rev-limited to 10000 rpm and need a rebuild after 4000 to 4500&nbsp;km. The valve train is a dual overhead camshaft configuration with four valves per cylinder. The Mecachrome V8 engine weight is {{Convert|326|lb|kg|0|lk=on|abbr=on}}. 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 high-power inductive (coil-controlled) ignition system. The engine lubrication is a dry sump type, cooled by a single water pump.

Mecachrome came to the GP2 Series in 2005, and by 2005 was clearly the dominant engine manufacturer. Starting in 2005, they became the only engine manufacturer in the GP2 Series, and continued in that capacity through 2016. Mecachrome also has a mutually beneficial technical relationship with Teos Engineering of Montigny-le-Bretonneux. They will continue working together for on-going research and development, engine maintenance and trackside support for the Mecachrome GP2 V8 racing engine at all GP2 Series venues.

During that time, since the GP2 Series had only one engine manufacturer, Mecachrome still focusing on minimizing engine failure and minimizing costs instead of defeating rivals. As such, the engines were moderately de-tuned. The engines proved themselves to be quite durable—there had been no engine failures at all F2 tracks from 2005 to present, which also lowered the number of crashes. Most of the engines, including those used for the Monaco race, are used for multiple races and were intended to last 1,100 miles between rebuilds. The Mecachrome engines were only available via lease arrangement from Mecachrome currently.

[[Mecachrome V8108 GP2 V8|Mecachrome V8 GP2]] engines were crated and shipped to all GP2 teams on a serial-number basis as determined by the sanctioning body (FIA) to ensure equality and fairness in distribution.

===Fuel and lubricants components===
Since 2005, [[Elf Aquitaine|Elf]] exclusively provide the LMS 102 unleaded fuel and also [[Elf Aquitaine|Elf HTX 840 0W-40]] lubricants for all GP2 Series cars (except [[Total S.A.|Total Quartz 9000]] with [[ART Grand Prix]]).

===Gearbox===
The current [[gearbox]] has been manufactured by Hewland 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. The GP2 gearbox used a 6-speed [[Sequential manual transmission|sequential gearbox]] configuration with electronically controlled [[semi-automatic transmission|paddle-shifters]] + reverse gear operated by a button on the steering wheel.

===Wheel rims===
[[OZ Group|O.Z. Racing]] exclusively supplied wheel rims for all GP2 Series cars from 2005 until the final season.

===Tyres===
Similar to the 2011 change for Formula 1, Pirelli was the sole tyre supplier for the series. The GP2 Series runs the same compounds as F1. The front tyre size are 245/660-R13 and rear tyre size are 325/660-R13. Previously [[Bridgestone]] was the official tyre partner of GP2 Series in 2005 until 2010.

===Brakes===
[[Brembo]] supplied monobloc [[brake]] calipers and disc bells, which are exclusive to the GP2 Series. Hitco also supplies carbon brake discs and pads for FIA Formula 2 Championship. The brake discs are 278 x 28&nbsp;mm in size (similar to [[Formula One]]).

===Other parts===
The car also features internal cooling upgrades, a new water radiator, radiator duct, oil/water heat exchanger, modified oil degasser, new oil and water pipes and new heat exchanger fixing brackets.

===Steering wheel===
From 2011, XAP Technology exclusively provided the XAP single-seater GP2 Series steering wheel as well as XAP SX steering wheel dash display. The XAP steering wheel features 6 buttons in the front with 5 paddles (DRS, gear shift and clutch) in the back of steering wheel.

===Performance===
According to research and pre-season stability tests, the 2005 model can go 0 to 200&nbsp;km/h (124&nbsp;mph) in 6.7 seconds. The car has a top speed of 320&nbsp;km/h (198&nbsp;mph) meaning that it is the fastest single seater racing car behind [[Formula One car|Formula One]] and [[IndyCar Series]].{{Citation needed|date=January 2015}} The 2011 model can go 0 to 200&nbsp;km/h (124&nbsp;mph) in 6.6 seconds. The car has a top speed of 332&nbsp;km/h (208&nbsp;mph) with the Monza aero configuration.
