The #5 Mother Chassis machine shared by Reiji Hiraki and rookie Yusuke Tomibayashi was terminally damaged in the season finale when Tomibayashi was rear-ended along the start/finish straight by the apr Toyota Prius of Yuhki Nakayama during a safety car period.
Although Tomibayashi was unharmed, subsequent inspection of the car's standard Dome tub indicated that it was unrepairable, throwing the future of Team Mach - which has run the 86 MC since 2015 - into doubt.
