How does the Acura SH AWD system work?
SH-AWD also uses the same arrangement but adds a unique differential unit in the rear that does two things. First, it has a gearset to “speed up” the rear wheels so that when they are connected, they spin 1.7% faster than the fronts. (The old RL used a variable ratio system but it is no longer used.)
Why do I get Shawd warning on my Acura MDX?
They determined the EGR valve was bad and changed it out. They also pulled the manifold and cleaned the air ports leading to it. They were confident their work would fix both the Check Emissions and SHAWD warnings. So far they seem to have been correct. Here’s hoping I can stay warning free for a while.
What’s the difference between SH AWD and SH-AWD?
When fully connected the power is split 50/50 assuming all wheels have traction. SH-AWD also uses the same arrangement but adds a unique differential unit in the rear that does two things. First, it has a gearset to “speed up” the rear wheels so that when they are connected, they spin 1.7% faster than the fronts.
Which is best Acura or Honda AWD system?
Aside from the fact that Honda/Acura doesn’t have a RWD drivetrain to borrow, the benefit main benefit to a transverse engine layout is improved interior packaging. “Super Handling All Wheel Drive” may not have been the best name for the system, but it is arguably the best AWD system you can tack onto a transverse FWD platform.

What kind of AWD system does Acura RLX Sport Hybrid use?
The type 4 (2014 Acura RLX Sport Hybrid SH-AWD) is totally different than the rest types: its front wheels are driven by the gas engine, and the rear wheels are driven by an electric motor. This SH-AWD is not within this article’s scope of discussion. Below image is the SH-AWD system used on the Acura RL.
How is torque distributed in an Acura RL AWD?
SH-AWD. As first implemented in the Acura RL, SH-AWD allows torque to be continuously distributed between front and rear wheels from 70% front/30% rear to 30% front/70% rear, with up to 100% of the rear power being distributed to the outer left or right wheel to assist in cornering and dramatically reducing understeer.
What kind of acceleration does an Acura RL have?
The Acceleration Device was first introduced in the flagship Acura RL sedan, and continues in the MMC versions of the Acura RL sedan. This more complex configuration appears to be unique among the SH-AWD equipped Acuras.
