The Importance of Speed Management in Turns

Understanding Weight Transfer and Corner Entry Speed

When approaching a turn in a vehicle, one of the primary considerations is the speed at which you enter the turn. This decision is crucial for both safety and performance. When you brake before entering a turn, you initiate a process known as weight transfer. As the suspension compresses, more weight is transferred to the front wheels, increasing their grip and effectiveness on the road. This is particularly important for the vehicle to effectively perform the turn. Conversely, if you enter a turn at a speed that exceeds the corner's limits, the tires will wear heavily, and in many cases, you risk losing control of the vehicle. Good tires, no matter the quality, are expensive, and poor tires are even more so in terms of performance and longevity.

Impact of Speed on Safety and Vehicle Stability

For certain vehicles, such as tractor trailers, large trucks, and SUVs, not slowing down sufficiently before a turn can lead to a significant risk of tipping. The weight distribution in these types of vehicles is a critical factor that can affect their stability. In contrast, with smaller vehicles, failure to slow down can lead to loss of control, potentially causing mechanical failures due to excessive stress on the suspension and tires. It's therefore essential to maintain a safe and strategic speed when approaching any turn, regardless of the vehicle's type.

For any vehicle approaching a turn, there is a maximum speed at which it can safely navigate the curve. This maximum speed is influenced by the vehicle's performance capabilities and the road conditions. Professional drivers like Max Verstappen and Denny Hamlin can often approach this speed within a small margin of error, but the vast majority of drivers will not be able to achieve it without losing control or risking a crash. As such, it's crucial to brake early and hard to reduce the speed to an appropriate level for the turn. This not only ensures safety but also prepares the car for a smoother and more controlled turn.

The Role of Braking and Acceleration in Turn Management

Braking is a vital part of the turning process, not just for deceleration but also for stability. By applying the brakes, the vehicle is compressed, and the weight is redistributed, making it more stable for the turn. This is particularly beneficial for motorcycles, where the act of braking can also reduce the wheelbase, allowing for a tighter turn. In a car, maintaining poor or excessive brake input can unsettle the vehicle and hinder its performance. Therefore, smooth and judicious braking is crucial for optimal cornering performance.

Exiting a turn at the apex (the tightest part of the turn) is equally important as the entry. The vehicle should be at its maximum speed as it leaves the turn, ready for acceleration. This requires precise timing and careful control of the throttle to maintain the car's stability and performance. The principle of "slow in, fast out" is often cited as the best approach, but this can vary depending on the vehicle's capabilities and the driver's skill.

Advanced Driving Techniques and the Use of Weight Transfer

To optimize the turning process, advanced driving techniques can be employed. For example, in low traction situations or when setting up for the next turn, a technique known as a Scandinavian flick may be used. This involves intentionally unsettling the car to achieve a quick turn in. This technique, though advanced, can significantly improve performance in such scenarios. Additionally, exploring the limits of a car's handling can be achieved by understanding and utilizing weight transfer.

Most cars are designed with a 50:50 weight distribution, allowing for dynamic adjustments that can enhance turn performance. By understanding how these adjustments affect the car's behavior, drivers can negotiate turns more efficiently. Enrolling in an advanced driving course can help drivers to develop the skills required to manage speed, braking, and acceleration effectively, thus improving overall driving performance.

Conclusion

Managing speed, braking, and acceleration is a critical aspect of safe and efficient driving. Whether on the street or in a competition, understanding the principles of weight transfer and corner entry speed can significantly enhance a driver's performance. By adopting the right techniques and maintaining control, drivers can not only improve their safety but also their car's handling and overall performance.
