Can You Improve the Handling of a Renault Megane RS with a Limited-Slip Differential?

When it comes to sport cars, the Renault Megane RS always grabs the attention. This car is a versatile machine, combining the practicality of a family car with the performance of a sport car. The RenaultSport division has always managed to strike a perfect balance between delivering a thrilling drive and maintaining everyday usability. One of the key performance-enhancing features in the Megane RS is the limited-slip differential, often referred to as the ‘LSD’. But what exactly is this, and how does it improve the handling of the car?

Discovering the Renault Megane RS and its Performance Features

The Renault Megane RS, with its distinctive sporty aesthetics and impressive performance, is the epitome of a versatile car. The car’s standard offering includes a powerful 1.8-litre engine that delivers impressive torque, enabling the car to accelerate from 0 to 60mph in less than six seconds. The car’s performance is further complemented by a rigid, well-tuned chassis, large alloy wheels, and grippy sports tyres.

However, the real secret to the car’s impressive handling lies in its limited-slip differential. This feature is typically found in high-performance sports cars. Unlike regular open differentials, which send equal torque to both wheels irrespective of the traction available, a limited-slip differential adjusts the torque sent to each wheel based on available traction. This helps the car maintain better control and handling, particularly when cornering at high speeds.

The Role of the Limited-Slip Differential in the Megane RS

Understanding the role of a limited-slip differential in a car like the Renault Megane RS requires a basic understanding of car dynamics. When you’re driving around a corner, the wheels on the inside of the turn travel a shorter distance than the wheels on the outside. To accommodate this, cars are equipped with a differential, which allows the wheels to spin at different speeds.

In a standard differential, if one wheel loses traction and starts to spin, power will be redirected towards that wheel, leading to a loss of control. However, a limited-slip differential prevents this by redistributing the torque to the wheel with the most grip, thereby improving control and stability.

In the context of a sport car like the Megane RS, this translates to improved handling and cornering performance. The limited-slip differential allows the car to take corners at higher speeds without losing traction, providing a more exciting and engaging driving experience.

The Impact of the Limited-Slip Differential on the Renault Megane RS

The limited-slip differential’s impact on the Renault Megane RS is monumental, contributing significantly to the car’s handling and performance. In particular, it shines when the car is driven aggressively, either on a racetrack or on a winding road.

With the limited-slip differential, the Megane RS exhibits excellent front wheel control, enabling the car to take sharp turns without losing traction. The rear wheels are also kept in check, ensuring that the car’s rear end doesn’t slide out during high-speed cornering. This gives the driver more confidence to push the car to its limits, knowing that the car’s handling and control won’t be compromised.

Moreover, the limited-slip differential also enhances the Megane RS’s performance in wet or slippery conditions. With the LSD, the car can maintain traction and control even when one wheel slips, making it safer to drive in adverse weather conditions.

Limited-Slip Differential vs. Electronic Differential Lock

While the limited-slip differential is a key feature in high-performance cars like the Megane RS, it’s worth noting that some cars, including certain versions of the Megane RS, come equipped with an electronic differential lock (EDL) instead. This system, also known as ‘torque vectoring’, uses the car’s braking system to simulate the effect of a mechanical LSD.

When the car’s sensors detect a wheel losing traction, the EDL applies the brakes to that wheel, redistributing the torque to the wheel with more grip. Although this system can be effective in improving handling, it doesn’t quite match the smoothness and responsiveness of a mechanical limited-slip differential.

In a matchup between an EDL-equipped Megane RS and an LSD-equipped Megane RS, the LSD-equipped car would likely have the edge in terms of overall handling and performance. However, the difference might not be noticeable in everyday driving, only becoming apparent when the car is pushed to its limits on a racetrack.


In conclusion, the limited-slip differential plays a vital role in enhancing the handling and performance of the Renault Megane RS. Whether you’re an avid track-day enthusiast or a casual driver who enjoys a spirited drive every now and then, you’ll definitely appreciate the improved control and stability offered by the LSD. However, it’s important to note that the LSD is just one part of the equation – the Megane RS’s impressive performance is also down to its powerful engine, well-tuned chassis, and grippy tyres. So, if you’re considering upgrading your car with a limited-slip differential, you might also want to consider upgrading these other components to get the most out of your car.

Exploring the Benefits of a Limited-Slip Differential in Circuit Racing

The benefits of a limited-slip differential in the Renault Megane RS are particularly noticeable in the world of circuit racing. For enthusiasts who enjoy putting their cars to the test on a racetrack, the LSD can make a significant difference.

In circuit racing, drivers often have to navigate sharp corners at high speeds. On these occasions, the LSD-equipped Megane RS shines by maintaining control and stability. When taking a corner quickly, the LSD allows the inner wheels to spin at a slower speed than the outer wheels, which are covering more ground. This reduction in torque to the inner wheels and the increase to the outer wheels with more grip enables the car to maintain traction and stability, even at high speeds.

Moreover, the LSD-equipped Renault Megane RS minimises torque steer, a common issue in high-performance front wheel drive cars. Torque steer occurs when power delivered to the front wheels during acceleration causes a pull to one side. The LSD mitigates this by evenly distributing the engine’s power between the wheels, giving drivers better control and making the car easier to handle.

The LSD also enhances the Megane RS’s performance in wet or slippery track conditions. Even when one wheel slips, the LSD redistributes the torque to the wheel with the most grip, maintaining control and allowing the driver to continue racing without major interruptions.

Choosing the Right Megane RS for You: Cup Chassis vs. Sport Chassis

When considering a Renault Megane RS, it’s worth noting that the car comes in two versions: one with a Cup Chassis and another with a Sport Chassis. The Cup Chassis version is equipped with a limited-slip differential, while the Sport Chassis version comes with an electronic differential lock.

The Renault Megane RS with a Cup Chassis is often considered the more track-focused of the two. With its limited-slip differential and a registered joined front rear suspension system, this version of the Megane RS offers improved handling and is better suited to aggressive driving on racetracks. Additionally, the Cup Chassis version comes with larger, 19-inch alloy wheels, which offer greater grip and stability.

On the other hand, the Sport Chassis version of the Megane RS, with its electronic differential lock, is more suited to everyday driving. Although it lacks the LSD, its sport chassis and front wheel drive system still deliver an impressive performance on the road.

Both versions of the Megane RS offer a compelling mix of performance and practicality. The choice between the two ultimately comes down to your driving preferences and how you plan on using the car.


To sum it up, a limited-slip differential undoubtedly enhances the handling and performance of the Renault Megane RS, particularly in high-speed and aggressive driving scenarios. Whether you are navigating a racing circuit or simply enjoying a spirited drive on a winding road, the LSD-equipped Megane RS provides a thrilling, responsive and controlled driving experience.

However, it’s key to remember that while the LSD is vital, it’s not the only factor contributing to the Megane RS’s exceptional performance. The car’s powerful engine, rigid chassis, and grippy tyres also play significant roles.

Hence, if you’re considering a Megane RS or planning to upgrade your existing car with a limited-slip differential, also consider other performance-enhancing features to ensure your car delivers a comprehensive high-performance driving experience.
