SuperGT collaboration announced
ARTA, MUGEN and HRC announced a collaborative project in SuperGT — a notable manufacturer and racing partnership that hints at technical and marketing crossovers for the series. Those kinds of alliances often reshape car development and brand positioning in Japan’s top GT category. (x.com)
Honda’s factory racing arm is moving inside one of its best-known Super GT outfits instead of just supplying a car from a distance. For 2026, the No. 8 ARTA entry becomes “Team HRC ARTA MUGEN,” with Honda Racing Corporation assigning dedicated engineers to work directly with the team and its drivers. (supergt.net, supergt.net) That sounds small until you remember how Super GT works. The GT500 class is Japan’s top touring-car category, and tiny setup gains in aero, tires, and engine mapping can decide races by seconds over 300 kilometers. (supergt.net) ARTA is not a random customer team. ARTA stands for Autobacs Racing Team Aguri, the project former Formula One driver Aguri Suzuki launched with Autobacs in 1997, and it has been one of Honda’s flagship names in Super GT for nearly three decades. (arta.co.jp) M-TEC, better known by the brand Mugen, is Honda’s long-time performance partner rather than a separate rival. In Japanese racing, Mugen has spent decades building engines, race parts, and competition programs that sit close to Honda’s factory effort without always wearing the full factory badge. (supergt.net, supergt.net) Honda is also changing the hardware at the same time. Its five GT500 cars switch to the new Prelude GT-based machine for 2026, replacing the Civic Type R-GT era with a fresh development cycle across the whole lineup. (supergt.net, supergt.net) That is why the engineer move matters more than the name change. Honda said it will create a new Super GT technical director role from January 1, 2026, add several engineers to support all five Honda Prelude GT cars, and place another dedicated group specifically with the No. 8 team to feed development back into the program. (supergt.net) The split inside ARTA makes the structure even clearer. Car No. 8 becomes the HRC-linked works-style entry under supervisor Aguri Suzuki, while car No. 16 stays as “ARTA MUGEN” under supervisor Keiichi Tsuchiya. (supergt.net, supergt.net, supergt.net) The driver lineups show Honda stacking experience around that new structure. Kakunoshin Ohta returns to Super GT in the No. 8 car alongside Hiroki Otsu, while Tomoki Nojiri moves to the No. 16 car and pairs with Ren Sato. (supergt.net, supergt.net, supergt.net) In plain terms, Honda now has one ARTA car that looks more like a laboratory and one that still looks like a top independent-style partner. When a manufacturer launches a new GT500 car, that kind of two-track structure can speed up learning because one side chases factory development and the other side races with a slightly different rhythm. (supergt.net, supergt.net) It also gives Honda a cleaner story to sell. “Team HRC ARTA MUGEN” puts Honda Racing Corporation, ARTA, and Mugen in one name, which ties the factory badge, the famous team brand, and the tuning brand to the same Prelude GT program on the grid. (supergt.net, supergt.net) So the announcement is not just a decal change before Round 1. Honda is reorganizing who develops the new Prelude GT, who gets
