Which is NOT typically considered a factor when determining the turn-in point for a medium-speed right-hander?

• A. Entry speed
• B. Corner radius
• C. Fuel type
• D. Track surface

Answer: (C)

When planning where to begin turning into a medium-speed right-hander, the driver focuses on how fast you’re entering, how sharp the bend is, and how much grip the track surface provides. Entry speed sets how much you need to brake and how you must coordinate steering to stay on a stable path into the corner. The corner’s radius tells you how tight the arc will be, so a sharper bend usually requires initiating the turn earlier to follow the tighter line and hit the desired apex. Track surface affects available grip; on a high-grip surface you can commit to steering earlier with more confidence, while on a low-grip surface you’ll adjust by delaying or smoothing inputs to avoid losing traction. Fuel type doesn’t directly change these factors, so it isn’t used to determine the turn-in point.
