15th Anniversary of Super Handling All-Wheel Drive™

Anniversary All-Wheel Drive

Acura is celebrating the 15th anniversary of its industry-leading Super Handling All-Wheel Drive™ (SH-AWD®) technology with a new video that illustrates SH-AWD®'s performance prowess and unique history. Acura's groundbreaking SH-AWD® technology has long set the bar for performance-enhancing torque vectoring AWD and is now offered on five of six Acura models in either mechanical (SH-AWD) or electric (Sport Hybrid SH-AWD) form. Additionally, Acura will surpass the one-million mark in global sales of SH-AWD®-equipped vehicles later this year. The first generation of Acura SH-AWD debuted (in 2004) on the 2005 RL sedan as the world's first torque-vectoring all-wheel drive system.

 
 

New RDX with 4th generation SH-AWD

 
 

The Acura AWD technology, which dynamically distributes engine torque for enhanced handling and cornering performance, has been continuously advanced through multiple generations of development and deployed on Acura's most popular models. The newest and most powerful generation of mechanical Super Handling All-Wheel Drive (SH-AWD) debuted on the 2019 RDX in June 2018, boasting 40 percent more torque capacity at the rear axle, quicker front-to-rear torque transfer and 30 percent quicker transfer of torque between the left and right rear wheels. Acura SH-AWD was expanded into the electrified realm with the launch of Sport Hybrid SH-AWD in the 2014 RLX Sport Hybrid. This was followed by the second generation NSX, the only electrified supercar on sale today, and 2017 MDX Sport Hybrid.

 
 

Acura TLX SH-AWD Rear Differential

 
 

Sport Hybrid SH-AWD utilizes instantly available electric motor torque to elevate dynamic performance and efficiency. The Acura MDX and RLX apply a rear-mounted Twin Motor Unit (TMU) and front-mounted gas-electric hybrid engine, while the Acura NSX features a unique mid-engine sports car configuration with a front-mounted TMU. Despite configuration differences, all three Sport Hybrid models apply the same technology and utilize many of the same components across supercar, SUV and sedan.

Acura SH-AWD: Through the Years

1st Generation SH-AWD

 
 

RL (2005-2012)

 
 

The world's first all-wheel drive platform that actively and continually distributes torque not only to enhance traction, but also to elevate cornering performance. By overdriving the rear wheels SH-AWD can provide an inward yaw moment while accelerating into and through corners.

2nd Generation SH-AWD

 
 

 

 MDX (2007-2015) & RDX (2007-2012)

  

TL (2009-2014) & ZDX (2010-2013)

 
 

SH-AWD is enhanced with Hill Logic that automatically adjusts the front/rear torque split based on the grade of the underlying surface as well the integration of Vehicle Stability Assit (VSA) and, in 2009, Traction Control Systems (TCS). The rear differential is constantly overdriven by 1.7 percent.

3rd Generation SH-AWD

 
 

  

MDX (2016-Present) & TLX (2015-Present)

 
 

The 3rd generation system utilizes a 25 percent lighter rear differential with reduced friction and increased yaw effect. The rear differential is constantly overdriven by 2.7 percent, providing a greater torque-vectoring effect across a broader spectrum of driving conditions to further enhance cornering capability.

4th Generation SH-AWD

 
 

 

RDX (2019-Present)

 
 

The newest version of Acura's mechanical SH-AWD is more compact than before while offering 30 percent faster response and a 40 percent increase in maximum torque capacity.

Sport Hybrid SH-AWD

 
 

  

RLX (2014-Present) & NSX (2017-Present)

 

MDX (2017-Present)

 
 

The first and still only electric torque-vectoring system in the world to enhance every element of dynamic performance – acceleration, braking and cornering – able to apply both positive and negative electric motor torque with instantaneous response on- and off-throttle.
