Leveling up NFT gives **two level-up points** to upgrade Boost and Endurance.

## Boost

| Boost level range | Effect                                                                                                 | Boost level 40              |
| ----------------- | ------------------------------------------------------------------------------------------------------ | --------------------------- |
| 0\~40             | At each levelup, max boost distance increases by 1\~1.2km.  Boost distance give 10% higher data point. | Max boost distance 40\~48km |

Purchase and refill max boost distance to use boost distance to get 10% reward boost.

## Endurance

For the resilience feature, tires wear out at reward driving.  In default, 10% of reward distance is charged for repair. The higher Endurance, the less repair cost charged by repair cost factor.&#x20;
