Never short of ideas, GTA — the series promoters — know that the championship is one of the toughest in the world and have made strategic alliances with other promoters worldwide to help maintain its stability.

Endurance-Info caught up with GTA CEO Masaaki Bandoh to discuss the state of GT500, its relationship with DTM promoter ITR, its relationship with the ACO as well as plans of a “mother chassis’ for GT300.

What is your assessment of the new GT500 class?

“The association with ITR allows us to have common regulations in order to contain costs, which is a good thing. The new GT500 car has more downforce than last year’s, which means they’re even faster.

“The tire manufacturers have worked hard in this area. Michelin and Bridgestone have been performing from the start, whereas Dunlop and Yokohama had a little more trouble in the first meetings.

“We’re allowing manufacturers to change [aero configurations] once a year. So far only Nissan has made that choice and now has a high-downforce version. The Honda NSX-GT Concept complies to the JAF GT500 regulations.

“Starting at Sugo, Honda received permission to modify the cooling by increasing its front air intakes, as well as the radiator and side cooling. Before Sugo, the heat tended to deform the rear deck. Furthermore, the Honda runs with 15 kg less weight.”

Does the cooperation with ITR continue?

“At present, DTM cars cannot run in Super GT. GTA has proposed to Hans-Werner Aufrecht (ITR boss) to take 15 GT500 cars to China next year during the DTM meeting. This would be part of a joint event, but without the two championships running together.

“A DTM engine produced 520 horsepower while a GT500 is at 580 horsepower. One series has common tires where the other has very specific and sensitive [open choice] tires.

“In 2017, the technical regulations will be the same but GTA does not want a spec tire manufacturer. To run together [with DTM], it would be a matter of a compromise.

“If the German [cars] had to come to Japan, why not open up the air restrictor and vice versa if Japanese cars were to come to Germany?

“The culture between the two countries is different. Germans work a lot on the marketing side and promotion, which is not the case in Japan.

“GTA has proposed to use Super GT as a marketing tool but manufacturers want to spend their resources in the development of the cars.

“DTM wants to keep its sporting regulations and so do we. The idea is to have a common set of international regulations, with the same sporting regulations.”

When will Japanese cars be able to race in Germany and vice versa?

“If the Japanese manufacturers want to race in Germany, they must continue here in Japan with Super GT. For clarification, GTA does not wish to race in Europe or the United States.”

Will there be identical technical regulations between DTM and Super GT in 2017?

“ITR will adopt the 2.0-liter turbo. It’s complicated to develop 580 horsepower with a 2.0-liter turbo because it requires a lot of money. ITR has proposed to adopt a common Bosch hybrid system.

“By applying this method, it would reduce the costs of developing the cars. To date, only BMW has shown interest. If we can have 90 percent identical regulations, it will be good.”

Is the next step developing the common “Mother Chassis” in GT300?

“We believe in this new concept. FIA GT3 cars are made by manufacturers with the introduction of customer support. The GT3 ‘Mother Chassis’ goes against that idea.

“It is increasingly difficult for teams to run GT3, train the mechanics and engineers. If we continue down this road, the race will be the playground of the manufacturers and not the teams.

“With our concept each team will make a difference. For now, only Toyota has taken up the challenge but others will follow with the permission of the respective brands.

“There are already four confirmed orders. There are no plans to export the concept to Europe, where manufacturers are more highly represented. Teams will also have a GTA-badged engine.”

Will GTA continue to work with SRO?

“We’ve asked for help from the SRO in the implementation of GT300 BoP because we believe their BoP established in Blancpain is the best. The teams also agree.

“I visited the 24 Hours of Spa and Stephane Ratel will come to one of our races before the end of the season. In 2015, we will again use the BoP established by SRO.”

The Asian Le Mans Series had a standalone race at Fuji the same weekend as Super GT at Suzuka. Can we see a collaboration between the two series in the future?

“We helped the series last year by bringing in GT300 cars during a meeting. It’s no secret that we wanted to run the GT500 champion at the 24 Hours of Le Mans last year, even outside of the ranking (Garage 56) but the ACO did not accept.

“In the future, why not have Super GT, GT Asia and Asian Le Mans Series compete in a common race, maybe even a 24-hour event. GTA is open to offers.”

    Sounds like a plan! Merdeka comes to mind… 😀

      Or just invite DTM cars to the Suzuka 1000 km, then run the ADAC 1000 km Nürburgring at the Nordschleife together with Porsche Supercup, German and French Cup.

    It’s pitiful that the ACO wouldn’t allow a SuperGt500 car run at LeMans. I guess they’re too worried that it will outrun the P2’s since at Fuji the Gt500’s are faster than the P2’s.

      maybe because the car would be too awesome and take too much atention to something outside the FIA environment.

      The RC-F GT500 qualified faster than the Rebellion LMP1 and Fuji!

      the garage56 entry is for experimental cars, so gt500 is not right for that concept
      that said, it would be totally awesome if gt500s were the platform for a new “gt1” class. only problem is that these are incredibly expensive cars. the japanese makes put a lot of money in these projects, and the european makes wouldn’t put nearly as much investment in it.
      but one can dream. the fact that they could be faster than p2 and even some p1 just makes it all the more awesome if you ask me.

        Maybe add a KER/ERS to the GT500? Team SARD did say that they want the garage 56 slot. Imagine if the ACO allowed GT500/DTM as the new GT1 or GTP. Thats 6 manufacturers over night!

    How not to love GTA?!
    With a lot of series worldwide going the wrong direction these days it’s refreshing to see such open minded and well oriented organization.

      DTM is just a marketing show (yet they haven’t solved the issue with aerodynamics and overtaking).

      Super GT is a place to develop technology, like Audi does in LMP1.

    Did any of you guys catch the Suzuka 1000(Super GT rd 6)?

    GTA not wanting to go to USA or EU? why not the teams? and GTA could help in developing a Can-Am/Trans-Am cup style series hosted by either the SCCA or IMSA.

      There’s talks about US DTM in 2017. But for that to happen IMSA/GTA/ITR need to convince Chevy, Ford, and Dodge to commit to the new series.

        I doubt it will happen. Both from a budget standpoint, and because it sounds like super GT and DTM are still father from agreement than they made it sound when they ‘merged’.

    I would love it if tuscc used those dtm cars as the prototypes like super gt does. They have a road presence to them to be a lead class that lmp2 and the Ford’s don’t have currently.

      I would rather keep the current GTLM cars, which are production-based.
