Let me try a better way of explaining the Tech Level:
The Tech Level is an overall speed rating for ***both*** your car and the AI opponents. Next time you finish a race, look at the leaderboard and you will see a Tech Level next to each AI opponent.
In the menu to pick races, the number next to each race is the Tech Level for that race. Races with higher Tech Levels have AI opponents with higher Tech Level and are harder to beat.
So, there are two ways of improving the performance of your car:
- Increase the overall speed with the Tech Level so you can compete with AI opponents that have higher Tech Levels
- Parts that have features like ERS efficiency also give you a boost in performance.
Does this make sense?
