The Vantage GT2 is based on the V8 engined Aston Martin Vantage road car but is designed to run on both standard race fuel or E85 bio-ethanol. DevelopmentDebuting in 2008 the GT2 is designed to meet FIA and ACO GT2 class regulations, the Vantage will become a customer car for use in the FIA GT Championship, American Le Mans Series, Le Mans Series, and 24 Hours of Le Mans. The Aston Martin Vantage GT2's engine is a modified version of the standard 4.3-litre AJ37 V8 from the road car. The larger 4.5-litre engine retains the road car’s cylinder block, heads and crankshaft, but uses competition components, including cylinder heads, con-rods, valves, camshafts and a racing exhaust system. The developed engine features a dry sump lubrication system allowing the engine to be positioned low in the chassis, for an optimised centre of gravity.[1] The car uses the original bonded aluminium chassis supplied by Aston Martin, but uses carbon fibre panels (exc roof) and features front splitter, rear diffuser, rear wing and a flat floor. The V8 Vantage GT2 has been tuned to be capable of running E85 ethanol or normal racing fuel, dependent on the racing series. [2]Aston Martin Racing has confirmed the entry of two upgraded GTE-Spec Vantage GT2s in the inaugural World Endurance Championship with a works team. Both the upgraded cars will debut in tests in January. They are reported to 'wear' Gulf liveries, much like those of the GT and Prototypes of Aston Martin have before. Racing historyAston Martin V8 Vantage GT2 saw its racing debut at the 2008 Grand Prix of Long Beach, driven by Paul Drayson, a former Minister of State in the United Kingdom, and Jonny Cocker, 2004 British GT Champion. The car will also be run on E85 fuel.[3] James Watt Automotive ran the V8 Vantage GT2 in the Le Mans Series 2008,[4] although the car failed to make the start of its debut race due to mechanical problems. Drayson Racing ran the V8 Vantage GT2 in the Le Mans Series 2009. It was confirmed that the JLOC would use a V8 Vantage GT2 in 2010 Super GT season. The Car was run under the name Aspeed triple A Vantage GT2 JMW Motorsport ran the V8 Vantage GT2 in the Le Mans Series 2010.[5] Aston Martin Vantage GT2's have also raced in many other series including the Le Mans Series and Intercontinental Le Mans Cup. Two Vantages also raced at the 2011 24 Hours of Le Mans: Jota Racing AMR and Gulf AMR Middle East. Both cars ultimately retired, one with mechanical issues and the other after losing control and spinning off the circuit, injuring the driver Mark Wainwright and damaging the car too seriously to continue. Upgrades and GTE VersionFor the 2012 season, Aston Martin Racing returned to a GT based program, after an ill-fated attempt the previous season with their LMP1 class petrol-powered contender, the AMR-One. With the Vantage GT2's specification varying slightly from the updated Le Mans GT2 (now GTE) regulations, development took place with the car relaunched as the Vantage GTE. Major upgradesPrimarily, this focussed on serviceability, a major drawback on the outgoing Vantage GT2. This included creating a new modular construction implementing a series of detachable bars in the front structure, allowing the engine to be pulled straight out of the car. This now allows the engine change process to be completed in less than an hour without any effect on suspension settings, unlike the old configuration, which could take upwards of four hours. The rear suspension and subframe have also been modified to aid serviceability. To increase safety, the fuel cell has been repositioned within the roll cage to reduce the risk of damage to its structure in an accident. Secondary upgradesOther upgrades include reductions in weight throughout, including weight reductions for many individual components such as the battery.[6] Improvements also included a new CFD-derived front-bumper, side skirt and rear wing - the latter an evolution of the Le Mans aero package which the Automobile Club de l'Ouest allowed the Aston Martin Racing team to run on the car for the entire season - "Aston Martin Vantage: The rear wing used at Le Mans in 2011 will be used during all the 2012 season with a 15 mm gurney and at Le Mans 2012 without gurney".[7] Modifications also improved cooling for the driver, a significant concern on the old model, which plagued Drayson-Barwell's 2008 ALMS season.[8] References1. ^{{cite web|url=http://www.astonmartinracing.com/content/allsites/documents/GT2%20brochure%20lowres_8281e96e-6222-4a31-b1f0-b3bca0a55b50.pdf |title=Aston Martin Racing Vantage GT2 brochure | publisher=Aston Martin Racing | date = 7 October 2010 | accessdate =7 October 2010}} 2. ^{{cite web | url = http://www.endurance-info.com/article.php?sid=4693&thold=0 | title = Aston Martin Racing révèle sa Vantage GT2 | publisher = Endurance-Info | date = 4 January 2008 | accessdate = 10 January 2008 | archiveurl = https://web.archive.org/web/20080107042026/http://www.endurance-info.com/article.php?sid=4693&thold=0 | archivedate = 7 January 2008 | deadurl = yes | df = dmy-all }} 3. ^{{cite web|url=http://www.motorsport.com/news/article.asp?ID=285329 |title=New car, same goals for Drayson-Barwell |publisher=Motorsport.com |date=14 April 2008 |accessdate=30 September 2010}} 4. ^{{cite web | url = http://www.endurance-info.com/article.php?sid=4845&thold=0 | title = James Watt Automotive engagera une...
