What are the advantages and disadvantages of changing from MR to FR?
In the case of FR monocoque equipped with an engine in the midship, it is a rear heavy, so understeer is strong, and it was initially a car with no front load.
Therefore, we made the target value closer to the FR vehicle.
For example, the oil tank was initially installed in the rear, but was finally installed in the front.
Therefore, the driver's impression was that nothing changed, although MR changed to FR.
That's how we were approaching FR weight distribution.
The biggest advantage of FR is braking.
Especially, the braking performance from the high speed range is improved.
Is there any change in the engine due to the change from MR to FR?
Although the basic specifications of the engine have not changed, engine accessories, gear train, and intake/exhaust system have been nearly new designed.
What do you think about today's practice results?
Toyota was doing a long run test during the mixed run time with GT300.
They have enough potential. We were 5km/h inferior at straight top speeds.
