In 2011, Rafael Unzurrunzaga approached Mosler Automotive, asking for a more powerful version of the firm's GT300.[1] Like the GT300, the GT600 used a space frame chassis, and shared the same carbon fibre bodywork.[2] However, the 300 hp (224 kW; 304 PS) engine fitted in the GT300 was replaced with a 7-litre Chevrolet LS7 V8, capable of producing 600 hp (447 kW; 608 PS).[2] A MoTeC ECU, dashboard and PDM system was fitted, and the GT600 became the first car to use the 6-speed sequential Hewland LWS gearbox.[1] The car was delivered to Unzurrunzaga in July 2011,[2] at Donington Park, where the car was also tested.[3]
The GT600's racing debut came at the Estoril round of the Spanish GT Championship on 17 July 2011, where Unzurrunzaga ran the car under the Blue Jumeirah Team banner.[4] Competing in the GTS class, he finished 14th overall, and sixth in class.[5] Unzurrunzaga then switched to the Red Bull Ring round of the International GT Open, but was unable to start either race.[6][7] Two months later, he returned to the GT Open, competing in the Catalunya round; having missed the start of the first race,[8] he could do no better than 24th overall, and tenth in the GTS category, in the second race.[9] Unzurrunzaga was classified eleventh in the Spanish GT Championship's GTS Driver's Championship, with six points.[10]
Following the Catalunya race, Unzurrunzaga entered the third round of the 2011–12 UAE GT Championship, held at Dubai Autodrome; however, he retired after 14 laps.[11] He finished 2011 by taking seventh overall, and fourth in the GTA category, in the following round, held at Yas Marina.[12] The fifth round of the season, and the first of 2012, was also held at Yas Marina; Unzurrunzaga won the first race of the day,[13] before taking second in the second race,[14] resulting in him finishing second overall.[15] The series then returned to Dubai, where Unzurrunzaga finished second.[16] The next round of the UAE GT Championship was also held at Dubai, but Unzurrunzaga was unable to start either race.[17][18] The series then returned to Yas Marina, but Unzurrunzaga was not classified in the first race,[19] and did not compete in the second.[20] This would be the GT600's last race;[4] Unzurrunzaga returned to Europe, and replaced the GT600 with a Mosler MT900R.[21]
