2022 Toyota 86 embraces sports car evolution with fresh looks, more power

  2022 Toyota 86 embraces sports car evolution with fresh looks, more power The Subaru BRZ's twin is finally here, and like the BRZ, the new Toyota 86 keeps the back-to-basics sports car formula in great shape.Toyota revealed the new 86 in Japan with partner Subaru showing off the BRZ for the first time locally. While the two wear different wrappers, the 86 is once again largely an identical car to the BRZ. Behind the Toyota Gazoo Racing grille sits a 2.4-liter flat-four engine, sans turbocharger, that makes 230 horsepower and 184 pound-feet of torque. We'll have to wait for US-spec units to see if the 86 actually makes a couple more horsepower than the BRZ's 228 hp, or if the kilowatts-to-horsepower conversion is generous.

GTD-Pro vs. GTD: Balance of Performance (BOP)

Both classes use the same, data-controlled BOP process. This is an extension of the current process of the IMSA.

Since the GTD-Pro is geared to factory-assisted teams and drivers, the new class on the racetrack reaches a higher level of performance than the GTD class. For this reason, the BOP is managed separately for each class.

GTD-Pro vs. GTD: Sporting rules

The GTD-Pro takes over the current sporting regulations of the GTLM with regard to driving rating, qualifying, starting and racing. GTD-Pro cars are exactly like currently the GTLM cars red underlayed start numbers and red LEDs for the position indicator.

In the GTD-Pro, the cars have to go into the race on which was qualified. Otherwise, there is a penalty. In contrast, the team in the GTLM is currently allowed to use all tires from your quota for the start of the race.

The GTD-Pro assumes the test restrictions of the GTLM class, which allow a maximum of eight test days. On the other hand, a limit of four test days continues to be valid in the GTD. However, it is allowed to drive drivers with bronze status, fully tested if they have a special approval of the IMSA. Wind channel and straight-line tests are prohibited in the GTD.

The GTD retains the current requirements for drivers with bronze or silver status. It remains with the qualifying process, which was introduced to the season 2021, namely that a driver with bronze or silver status drives the first qualifying session to drive out the starting position. Then there is a compulsory driver change for a second qualifying session in which there are points for the overall standings.
