FAQ
01. What is the meaning of the red and orange lines of Ayrton AI Coaching?

The lines depict the exact track turns where the most time can be gained by improving the driving or the vehicle setup. The section might be the entry, the apex, or the exit of turn, or even a combination of them. Ayrton will indicate one area with red and one with orange colour, where red is the area in which the most time can be shaved off.

02. How does Ayrton AI Coaching work?

The VPR AI algorithm identifies and calculates the perfect lap your vehicle could achieve at the specific session and track. It then compares your session’s best lap with the perfect lap and provides you the turns of the track where you can improve the most.

03. Which factors affect the vehicle's Acceleration?

The Acceleration is being affected by the power to weight ratio, Cd (drag coefficient), gear ratio, slipstreaming, tire pressures and even alignment.

04. Does the slipstreaming affect the vehicle Acceleration and the Driving Score?

Yes, the slipstreaming results in higher Acceleration figures. Also if the slipstreaming is not consistent, it may result in lower Driving Scores.

05. What is the VPR Vehicle Capability (VC) ?

The VPR VC is an index number that indicates the performance of the vehicle for the given track and conditions. The bigger the number is, the faster the vehicle is at the specific track.

06. Can I compare Driving Scores from different race tracks?

In many cases yes but there are some occasions where the morphohology of different routes vary significantly. Therefore, VPR’s recommendation is to compare and use as reference Driving Scores from the same track.

07. Does a better lap time give me more odds for a good Driving Score ?

It certainly does.

08. My lap time is worse than the previous session but my Driving Score is better. Why this happened?

This might happen for various reasons but most probably the overall grip level, due to track conditions or tyre wear, may be lower which results in a less capable vehicle. You were awarded a better Driving Score because you managed to use more efficient the currently available vehicle capabilities.

09. Any high Driving Score tips?

Use a certified instructor and in case you feel fading on your brakes, tyres, or engine power, cool down your vehicle and stop your session. After any issues have been resolved try a new session where you will have more chances for a better Driving Score.

 

10. Any high Driving Score technical tips?

A solid, balanced and reliable vehicle can provide consistent performance and more odds for high Driving Scores. Also consider using a vehicle that suits your driving skills.

11. With what kind of vehicles will VPR work?

At the moment in all cars, motorcycles, go-karts, e-scooters and trucks. Check terms 7.2 and 7.3 for some Driving Score related exceptions.

12. My session was ranked as Invalid. Why has this happened?

This might happen if the VPR algorithm realises that the actual performance of the vehicle does not match the data collected during this session.

13. Is it ok if I don't have a track focused vehicle?

Absolutely, this is the main purpose of VPR. As long as your vehicle is well maintained and performs consistently, it should enable you to focus solely on your driving.

14. What if the user is not able to push his vehicle at it's limits?

In this case a low Driving Score will be provided due to a relatively slow lap time. If the user drives slow, up to a certain extend, the driving session will be marked as INVALID.

15. What happens if the user is trying to "cheat" the algorithm by trying to achieve less lateral grip?

In most cases the VPR algorithm will identify any intention for cheating and will mark the driving session as INVALID. Even if the VPR algorithm could not do so, it is almost impossible to drive consistently on a specific grip level so the Driving Score will be lower than the one which could be achieved if the driver was trying to reach the vehicle’s limits. Check also Terms 2.1 and 2.2 regarding Fair Play.

07. DRIVING SCORE EXCEPTIONS

 “Vehicle Performance Rating” [VPR] is designed to provide a unique combination of data at a high level of accuracy. However the accuracy of Driving Score and Diff (Gap) may be compromised at some extent in the cases listed below:

7.1  Significantly different traction level on specific part of the track. Reasons might include a very bumpy section, a part of the course where there has been a liquid spill, a very wet spot while the rest of the route is dry, etc. [possibility for strict Driving Score].

7.2  Vehicles that due to their downforce, can produce significantly different lateral grip levels among turns of the specific track. Usually at vehicles that exceed 2.5g Maximum Sustained Lateral Grip.

7.3  Users who for any reason don’t feel comfortable pushing their vehicle close to its limits. Usually this can happen when they are not familiar with the track, or with the vehicle, or a combination of the two.

7.4  Laps with traffic.

7.5  Sessions with “short shifting”
