However, unfortunately, the treatment after the renovation work of the 100R course was not yet enough, and although the course itself was clean pavement, the sand treatment during the work remained, and the course was very dusty. It was a situation. Therefore, the driver said, “100R is the place where I want the most downforce, so I want to step on it including the shape of the rear wing. But I slipped in that situation, so I stopped,” commented Takuto Iguchi are doing.
Eventually, the time attack was canceled, and it ended at the level of checking the hard parts and checking the communication of staff going to the Nürburgring.
The next test was scheduled for three consecutive days in late February, and was scheduled for public release on the last day. However, in order to prevent the spread of COVID19 (new corona virus) infection, its public release was suspended and only tests were conducted.
There was an NBR machine that appeared in 20-year coloring. The body is shark skin coating on the roof, engine hood and door panels, with sponsor stickers around the rear and partially painted with shark skin.
The new design follows the STI color image and renews the body color. The WRX STI will be tested at Fuji Speedway again in March. At that time, it will be the final specification, and will participate in the preparatory QF battle in April, with a scheduled 24-hour race.
NBR20MY Specifications
Finally, let me tell you a little about the Subaru WRX STI NBR Challenge. The 2020-year specification WRX STI has been in use for the first time since 2018, and is being reviewed every year, including in all areas, including body improvements. The power train uses EJ type with 2.0L turbo. This is tuned for racing, but the performance is adjusted by installing an air restrictor by regulation. Anti-lag (misfire) is not adopted for the turbo. This is not adopted because it has a greater impact on fuel economy than dislike turbo lag.
The transmission is equipped with a Hewland sequential 6speeds dog mission and is participating in AWD. The subframe uses the improved type for the rally, but the basic layout of the suspension etc. remains the same as commercial（nomal) vehicles. Although it has been entirely remodeled for racing, changes from commercial vehicles will change rigidity and strength, but the basic frame remains the same as commercial vehicles.
The fuel tank is equipped with 100L. The refueling system at Nürburgring is the same type of nozzle used at gas stations in the city. For this reason, it is possible to refuel 100L non-stop if the air in the tank is good, but if the air is bad, it will stop at around 94L. Therefore, the tank shape has been changed this season, and it has been confirmed that non-stop entry up to 99L is possible. In previous experiments, it seemed to be working perfectly, and the pit stop time could be reduced to ten and a few seconds with a single operation. If you make 16 pits in the 24-hour race, you can save about 3 minutes, so you can simply run one more lap.
The tires are Falken commercial racing tires. It is a commercial slick tire, not a special tire. In addition, two types of rain, Intermediate and heavy rain, are permitted, so they use commercial racing rain.
