For2011, theLe Mans Prototype rules were changed to reduce costs.[5] As a result, theGinetta-Zytek GZ09S became obsolete, and theZytek 09SC, previously anLMP2-class car, became anLMP1-class car. In response to this,Zytek developed the car into the new Z11SN, and signed a deal withNISMO to use theNissan GT-RSuper GT'sNissan VK45DE engine.[6] This was a 4.5 litrenaturally-aspiratedV8 engine, producing approximately 450 hp (336 kW; 456 PS) in LMP2 specification.[6]Greaves Motorsport were the only team to enter a Z11SN in its first season,[7] with their chassis having originally been aZytek 07S.[8] The car was immediately successful, with a debut class victory (and third overall) at the6 Hours of Castellet, driven byKarim Ojjeh,Gary Chalandon andTom Kimber-Smith.[9] The season would prove to be a successful one; Greaves Motorsport took the class victory at the24 Hours of Le Mans, and the LMP2 Team's Championship title in the Le Mans Series.[4] At the end of the season, this chassis was retired, and three new ones were built.[8]
For2012,Jota Sport entered a Z11SN in theEuropean Le Mans Series (ELMS), finishing eighth in class in the first round of the season, the6 Hours of Castellet.[10] Greaves Motorsport bought two chassis, and also entered them in the ELMS.[8] Both teams also entered that year's24 Hours of Le Mans,[11] with Greaves' No. 42 car being the most notable entry – it was driven by formerFormula 1 driverMartin Brundle, his sonAlex, andLucas Ordóñez.[12] The No. 42 car finished eighth in class,[13] whilst the other Greaves car finished fifth,[14] and the Jota Sport entry failed to finish.[15] Greaves Motorsport finished third in class the European Le Mans Series that year, whilst Jota Sport finished tenth.[16]
In2013, Greaves Motorsport and Jota Sport both remained in the European Le Mans Series with their Z11SN chassis.[17] The season started successfully, with Jota Sport taking a victory at the2013 6 Hours of Silverstone.[18]Caterham Motorsport announced that they would be entering the24 Hours of Le Mans for the first time, using a Z11SN, withAlexander Rossi, Tom Kimber-Smith andEric Lux as their drivers.[19] The entry was a joint venture between Caterham and Greaves Motorsport,[20] with Greaves also entering a Z11SN under their own banner, driven byJann Mardenborough, Lucas Ordóñez andMichael Krumm.[21] Jota Sport also entered the event with a Z11SN, with their driversSimon Dolan,Oliver Turvey andLucas Luhr.[21] The Greaves Motorsport entry was the most successful of the three, as Mardenborough, Ordonez and Krumm finished fourth in the LMP2 category.[22]
The No. 38 Jota car took the LMP2 class victory at the 24 Hours of Le Mans
For 2015, the car was substantially developed as the Gibson 015S, following the purchase of Zytek byContinental AG that established Gibson Technology.[24] Jota Sport used it to finish second in the LMP2 class and 10th overall in the2015 24 Hours of Le Mans, 48 seconds behind the KCMG's Oreca.
In 2016, Strakka Racing finished 4th[25] in the LMP2 class and 8th overall in the2016 24 Hours of Le Mans using the Gibson 015S, the highest result for the prototype in the race.
