SH-AWD, or Super Handling All-Wheel Drive, stands as a hallmark of Acura’s innovative approach to enhancing vehicle performance and safety. This advanced all-wheel-drive system not only optimizes traction in various driving conditions but also significantly improves handling, making it a key feature in many of Acura’s models. Unveiling the complexities behind SH-AWD can provide a deeper appreciation for the engineering prowess that goes into creating vehicles that deliver superior driving experiences. This article aims to provide a quick overview of SH-AWD, breaking down the least understood Acura acronym.


What is SH-AWD?

SH-AWD is a highly sophisticated all-wheel drive system developed by Acura, the luxury vehicle division of Honda. Uniquely designed to enhance both the performance and safety of a vehicle, SH-AWD distributes power not only between the front and rear wheels but also between the left and right rear wheels. This distribution is dynamically adjusted based on driving conditions, driver input, and vehicle speed.

The system uses a series of sensors to monitor vehicle dynamics, including wheel speed, steering angle, and lateral G-forces. By analyzing this data, It can predictively allocate torque to the wheels that need it most, thereby improving traction on slippery surfaces and increasing stability during high-speed maneuvers. This intelligent power distribution ensures optimal performance, significantly enhancing the vehicle’s agility, especially in corners, and providing a more engaging driving experience.


Brief History of SH-AWD

The inaugural deployment of SH-AWD graced the automotive scene in 2004 with the launch of the Acura RL. This marked a significant milestone for Acura, signifying its commitment to innovating driving dynamics and safety. The introduction of SH-AWD was a testament to Acura’s pursuit of achieving an unparalleled blend of performance and control, setting a new standard for all-wheel-drive systems.

By ingeniously distributing power across all four wheels, not just fore and aft but also side to side across the rear axle, SH-AWD showcased a novel approach to enhancing vehicle stability and cornering precision. Over the years, the SH-AWD system has evolved through rigorous advancements and refinements, further cementing its position as a pivotal technology in Acura’s arsenal.

By 2019, Acura introduced the fourth generation of SH-AWD, integrating it into models such as the TLX and MDX, offering more efficient and dynamic torque vectoring. This iteration was notable for its ability to deliver up to 70% of the engine’s torque to the rear wheels and distribute 100% of that torque between the left and right rear wheels, showcasing an even greater focus on enhancing traction, control, and performance across a broader range of driving conditions. The evolution of SH-AWD underscores Acura’s ongoing commitment to pushing the boundaries of automotive technology to enhance the driving experience.


How Does SH-AWD Compare to Other All-Wheel Drive Systems?

Comparing Acura’s SH-AWD with other all-wheel drive (AWD) systems reveals its unique strengths and innovative approach to achieving superior traction and handling. Here, we take a closer look at how SH-AWD compares to three popular AWD systems from other auto manufacturers.

Audi Quattro

Quattro, Audi’s renowned AWD system, has been a key player in the automotive industry since its inception in the 1980s. It primarily focuses on enhancing grip and stability by distributing power between the front and rear axles through a series of differentials. While Quattro provides exceptional balance and traction, especially in slippery conditions, SH-AWD goes a step further by not only splitting power between the front and rear but also laterally between the rear wheels. This additional layer of dynamic torque vectoring allows SH-AWD-equipped vehicles to achieve improved cornering precision and agility, setting it apart from Quattro’s more traditional approach.

Subaru Symmetrical AWD

Subaru’s Symmetrical AWD is praised for its balanced design, which contributes to optimal weight distribution and stability. This system continuously powers all four wheels and adjusts power distribution based on traction needs. Despite its efficiency in various driving conditions, Symmetrical AWD lacks the dynamic torque vectoring capability of SH-AWD. 

Therefore, while Subaru’s system ensures reliability and enhanced control in adverse conditions, SH-AWD offers a more engaging and responsive driving experience by actively optimizing torque distribution for better cornering performance.

BMW xDrive

BMW’s xDrive system is another noteworthy contender, offering a technologically advanced approach to AWD. It intelligently distributes power between the front and rear axles as needed, enhancing traction and handling. xDrive also integrates with BMW’s Dynamic Stability Control to improve drivability. 

However, similar to the comparison with Audi’s Quattro, SH-AWD distinguishes itself with its ability to dynamically allocate power not just between the front and rear axles but also between the individual rear wheels. This distinction allows Acura vehicles with SH-AWD to exhibit enhanced lateral stability and agility, especially in turns, when compared to BMW’s xDrive.

While each of these AWD systems offers its unique advantages and core competencies, SH-AWD’s emphasis on dynamic torque vectoring endows it with an edge in enhancing vehicle maneuverability and driving dynamics, particularly in cornering situations. This makes SH-AWD particularly attractive to those seeking a spirited driving experience without compromising on safety or traction.


Unique Features of SH-AWD

In the landscape of automotive technology, Acura’s Super Handling All-Wheel Drive (SH-AWD) system represents a pinnacle of innovation and performance. This system, known for its exceptional capability to enhance grip and maneuverability, sets a high standard for all-wheel drive functionality. Below, we explore five unique features that distinguish SH-AWD from its competitors, highlighting the system’s innovative approach to delivering superior driving dynamics.

Dynamic Torque Vectoring

SH-AWD is renowned for its dynamic torque vectoring capability, which allows for the precise distribution of power not only between the front and rear wheels but also between the left and right rear wheels. This precision enables improved traction and cornering performance by autonomously allocating more power to the outside rear wheel during turns, hence reducing understeer and enhancing vehicle agility.

Predictive Power Distribution

Unlike traditional AWD systems that react to wheel-slip, SH-AWD anticipates driving conditions and driver input to proactively adjust power distribution. Utilizing sensors to monitor vehicle speed, steering angle, lateral G-forces, and other dynamics can predict the optimum distribution of torque across the wheels to improve stability and responsiveness.

Real-Time Data Analysis

The SH-AWD system continuously analyzes real-time data from various sensors throughout the vehicle. This encompasses wheel speed, yaw rate, steering angle, and more, enabling the system to make instantaneous adjustments to torque distribution for optimal performance under all driving conditions.

Enhanced High-Speed Stability

SH-AWD’s ability to dynamically adjust torque distribution enhances the vehicle’s stability at high speeds, making it particularly beneficial during rapid lane changes or when navigating curves at higher velocities. This results in a safer and more confident driving experience, especially on highways or in sporty driving scenarios.

Improved Traction in Adverse Conditions

The system excels in maintaining traction on slippery or uneven surfaces by sending power to the wheels with the most grip. This feature is critical in adverse weather conditions, such as rain or snow, where road grip is compromised, thereby significantly reducing the risk of slippage and improving overall safety.

These distinctive features illustrate why SH-AWD is more than just an all-wheel drive system; it’s a comprehensive approach to enhancing vehicle dynamics, safety, and performance, making Acura vehicles equipped with SH-AWD a preferred choice for drivers seeking an engaging driving experience.
