Nissan and NISMO took the first steps in defending their Super GT GT500 and GT300 class championships on home soil in Japan with the first pre-season test last week.
Forty-two cars gathered at the Okayama International Circuit in Mimasaka, Japan for the official pre-season test including four Nissan GT-R NISMO GT500 and four Nissan GT-R NISMO GT3 machines.
Formerly the home of the Pacific Formula 1 Grand Prix in 1994 and 1995, the 3.703 km (2.300 mi) circuit will host the opening round of this year's Super GT championship.
The two-day test marked the official GT500 debut for Blancpain Endurance Series champion Katsumasa Chiyo, who will team with NISMO legend Satoshi Motoyama in the No.46 S Road CRAFTSPORTS GT-R.
Former GT Academy champion Jann Mardenborough also continued his testing program on board the No.3 Nissan GT-R NISMO GT3 alongside Kazuki Hoshino.
New team colors for the No.24 Forum Engineering ADVAN GT-R GT500 were also seen in action for the first time with Daiki Sasaki and Masataka Yanagida at the wheel.
The No.12 Calsonic IMPUL GT-R of Hironobu Yasuda / João Paulo de Oliveira was fastest for Nissan on the opening day of the test, as all four GT-R entries were in the top 10 in times with the sixth, seventh, eighth and 10th fastest times.
The Japanese/Brazilian combo was also quick on day two in the No.12 entry to record the third fastest time with reigning GT500 champions Tsugio Matsuda / Ronnie Quintarelli in seventh place for the second consecutive day.
Mardenborough and Hoshino were fifth fastest in GT300 amongst a 27-car field on day one and sixth on day two.
Super GT testing continues next week at Fuji Speedway in preparation for the opening round at Okayama on April 9 to 10.
