Why is the speed of Elysee 120 mph so high?

System failure and excessive lubricating oil.

1, system failure. The reasons for exceeding the speed limit of Elysee 120 mph include sudden increase of throttle opening, slipping or damage of air-conditioning clutch, sudden loss of engine load, forced downshift of transmission computer or internal failure of transmission.

2. Too much lubricating oil. When the speed of Lishe 120mph is too high, you can check whether too much machine lubricating oil has been added. If there is too much lubricating oil, it will cause the oil to overflow to the rotating shaft of the machine, which will reduce the friction of the machine rotation and lead to too fast rotation speed.
