The apex of a right turn is the point where your vehicle is closest to the inside edge of the corner. It's a critical part of navigating a turn efficiently and safely.
Understanding the Apex
In driving, especially when discussing cornering lines or techniques, the apex refers to a specific geometric point within a turn. As defined, the apex is the point at which you are closest to the inside of the corner, also referred to as the clipping point. This point marks a transition phase in the turn.
Think of a turn as an arc. You enter the turn from the outside, move towards the inside (reaching the apex), and then move back towards the outside as you exit. For a right turn, the inside edge is the one on your right side.
Why is the Apex Important?
Hitting the correct apex is crucial for maintaining control, optimizing speed, and ensuring a smooth trajectory through the turn. It allows you to complete the turn using the widest possible arc, which minimizes the steering angle required and helps maintain momentum.
Key Benefits of Hitting the Apex:
- Optimal Speed: Allows you to carry maximum safe speed through the corner.
- Reduced Steering Input: Requires less steering lock overall.
- Smooth Transition: Facilitates a smoother transition from braking (or coasting) to accelerating.
- Better Exit Speed: Positions the vehicle for a stronger exit onto the next straight or road section.
The Clipping Point
The term "clipping point" is often used interchangeably with apex, particularly in motorsports. It literally refers to the point where you would theoretically 'clip' the inside edge of the corner if it were marked by a physical barrier. For a right turn, this is the inner right-hand boundary of the road.
What Happens After the Apex?
The reference highlights the actions that follow reaching the apex: "Once you have hit the apex you should be able to reduce the steering lock, start increasing the throttle and focus on the exit." This is the crucial transition phase:
- Reduce Steering Lock: As you pass the apex, you begin to un-steer, straightening the wheel.
- Increase Throttle: With the car becoming more stable and pointing towards the exit, you can start applying power.
- Focus on the Exit: Your attention shifts from the entry and midpoint of the turn to lining up for the road ahead after the turn.
Apex in Practice
While the geometric apex is the theoretically optimal point, drivers might use different "styles" of apex depending on the turn, the vehicle, and conditions. Common apex types include:
- Late Apex: Entering the turn wider and hitting the apex later in the corner, often used for sharper turns or when prioritizing exit speed onto a long straight.
- Early Apex: Hitting the apex sooner, typically used for less sharp turns or when preparing for another immediate turn.
- Geometric Apex: The theoretical midpoint of the corner's curve, often a good general target.
| Apex Type | Description | Typical Use Case |
|---|---|---|
| Geometric | The theoretical midpoint of the curve | General, balanced approach |
| Late | Hit closer to the exit of the turn | Sharp turns, maximizing exit speed |
| Early | Hit closer to the entry of the turn | Gentle turns, specific sequences |
Understanding and correctly identifying the apex for each specific turn, whether right or left, is fundamental to skillful and efficient driving. It's not just about reaching the closest point, but doing so as part of a smooth, controlled maneuver that sets you up for the rest of the corner and beyond.
