The 015S evolved from the Zytek Z11SN, itself a car built since 2011 as a replacement for the Ginetta-Zytek GZ09S under new Le Mans Prototype cost-reduction regulations. The Z11SN had been a competitive and durable package: Greaves Motorsport won the LMP2 class at the 24 Hours of Le Mans and the Le Mans Series team championship with it in 2011, and Jota Sport repeated that Le Mans LMP2 class victory in 2014.
In 2014, Continental AG completed its acquisition of Zytek Automotive, leading to a corporate split. Zytek Engineering, the motorsport-focused division based in Repton, Derbyshire, remained under the leadership of founder Bill Gibson and was renamed Gibson Technology on 1 October 2014. The prototype line was updated and relaunched as the Gibson 015S for the following season, carrying forward the core architecture of the Z11SN with substantial development work.
The Gibson 015S made its racing debut in 2015. Jota Sport, one of the primary users of the predecessor Z11SN, campaigned the 015S at the 2015 24 Hours of Le Mans, finishing second in the LMP2 class and tenth overall, just 48 seconds behind the KCMG Oreca 05 that took class honours.
In 2016, Strakka Racing entered a Gibson 015S at the 24 Hours of Le Mans and achieved the best overall result for the model at the race, finishing fourth in LMP2 and eighth overall.
The 015S represented the final development iteration of a prototype family that had been continuously competitive since 2011 under both the Zytek and Gibson banners. By 2017, Gibson Technology had transitioned its focus from building complete chassis to engine supply, becoming the exclusive provider of the GK428 4.2-litre naturally aspirated V8 — producing approximately 600 hp — for LMP2 cars across the European Le Mans Series, FIA World Endurance Championship, and IMSA WeatherTech SportsCar Championship.
Like its predecessor the Z11SN, the Gibson 015S was an LMP2-specification prototype intended primarily for the European Le Mans Series and 24 Hours of Le Mans. The Z11SN had originally used a Nissan VK45DE 4.5-litre naturally aspirated V8 developed from the GT-R Super GT's power unit, producing approximately 450 hp in LMP2 trim. The 015S received development updates to the chassis, bodywork, and aerodynamics as part of the transition to the Gibson brand identity.
The Gibson 015S marked the end of Gibson Technology's career as a full prototype constructor. The success of the Zytek and Gibson chassis throughout the early 2010s — including back-to-back Le Mans LMP2 wins in 2011 and 2014 — established the company's reputation as a reliable and capable builder. That reputation fed directly into Gibson Technology's next phase as the exclusive LMP2 engine supplier, a role it maintained for several years and which was extended when Gibson was awarded the tender for the 2028 LMP2 engine regulations. The lineage from Zytek to Gibson represents one of British motorsport engineering's more enduring contributions to prototype racing.
