What is the SH in Acura MDX?
The SH in SH-AWD stands for "Super Handling." In the Acura MDX, SH-AWD is an advanced all-wheel-drive system designed to improve traction and cornering by actively distributing torque between the wheels. This naming reflects Acura’s emphasis on performance-oriented handling as part of its drivetrain technology.
Breaking down the acronym
Here is what each part of SH-AWD represents and how it differs from a conventional AWD system.
- The "SH" portion stands for "Super Handling," highlighting the system’s focus on handling and agility, not just raw traction.
- The "AWD" portion stands for "All-Wheel Drive," indicating power can be distributed to all wheels rather than staying on the front wheels alone.
- SH-AWD uses torque vectoring to actively send torque to individual wheels, especially on the rear axle, to improve rotation through corners.
- It was introduced with the Acura MDX in 2007 and has remained a signature feature in subsequent MDX generations.
- In modern MDX models, SH-AWD works with traction and stability systems to enhance grip on wet or slippery surfaces and during aggressive cornering.
In sum, the "SH" in SH-AWD denotes "Super Handling," signaling Acura's performance-oriented approach to all-wheel-drive technology.
How SH-AWD works in the MDX
SH-AWD is an active system that continuously monitors wheel speed, throttle input, steering angle, and lateral acceleration to determine the optimal torque distribution. It employs a rear differential with hydraulic clutches to vector torque between the rear wheels and can bias torque toward the outside rear wheel during cornering to help rotate the vehicle more predictably. The system also coordinates with the vehicle's electronic stability controls to maximize grip in challenging conditions.
Key features of the SH-AWD system
The following points outline how the system translates its engineering into on-road performance.
- Torque vectoring at the rear axle redirects power to the outside rear wheel in corners to help rotate the MDX more naturally.
- Active front-to-rear torque distribution ensures better traction when accelerating or climbing hills, especially on slick surfaces.
- Integration with Vehicle Stability Assist (VSA) and other safety systems helps improve stability during cornering or sudden maneuvers.
- The system operates automatically, delivering improved grip and handling without requiring driver input beyond standard driving.
In short, SH-AWD's torque-vectoring capability, combined with all-wheel drive, provides a measurable benefit in handling and traction across road conditions.
MDX model coverage and history
Since its inception with the MDX in 2007, SH-AWD has been a defining feature of Acura's SUV lineup. The current generation of the MDX, introduced for the 2022 model year and carried forward, continues to offer SH-AWD as part of its drivetrain options.
Summary
The SH in SH-AWD stands for Super Handling, signaling Acura’s emphasis on performance-oriented all-wheel-drive capability. SH-AWD automatically balances power between the front and rear axles and, on the rear axle, can vector torque to either rear wheel to improve cornering and stability. Introduced with the MDX in 2007, this technology remains a core attribute of the modern MDX, delivering enhanced grip in wet or slippery conditions and more confident handling during turns.
