Torque vectoring all-wheel drive systems (AWD) like Honda's i-VTM4 and Acura's SH-AWD can provide both fun and capability in snow, mud and gravel as well as sealed surfaces. Both these systems are very similar, but do they work and what makes them special? In this video we take a look at i-VTM4 in the 2019 Honda Pilot, Ridgeline and Passport, as well as SH-AWD in the 2019 Acura MDX and RDX.

      Just got a 2019 Honda Pilot EX-L AWD. Love so far, since it's my second Pilot.

      Driving Sports TV I prefer either SH-AWD or Symmetrical AWD (with either a traditional automatic or manual trans)

      @Drewbie85 Same as Toyota and Honda, just they use more input sensors, like angle etc.

      Great Video. Thanks. I am currently and looking at a RDX. I had a 1990 4 door legend L which I just sold. Yes car is mint. I miss it every day. Acura's just drive fantastic.
      MY Legend was effortless driving also.

      Thank you for doing these videos for us! Obviously for me to go out and do this in the real world, I just can't. Dealer would be like what do you want to do, etc. Great to see this. Can you do a Traverse High Country or new Enclave to see how their torque vectoring rear operates?

      For awd, either torque vectoring or just gtfo. All those awd/4wd crap from Toyota is a lie even with high end Lexus Lx. Toyota is still using 40 year old 4wd system until the 2019 rav4. Get the RDX or other European real awd.

      “Proactively sends power to the back.” That’s just a marketing way of saying it’s mainly front wheel drive. It may be more sophisticated than lesser systems, but it still has to wait for the system to detect when to send power to the back. Then it has to actually mechanically do it. The time it takes to do that can be critical if you encounter black ice on a front wheel while turning. This is inferior to AWD systems from Subaru, Audi, and some Toyotas (4Runner limited and Landcruiser)which send power to each wheel at all times.

      How many MDX drivers notice the transmission failing to respond to pedal input or failing to shift when you hit the gas while rolling in traffic or while on the highway at speed? Theres a serious problem with those 9 speed transmissions that Acura is covering up

      The best feature of SH-AWD is the yaw detection. When offroading, towing or just starting off on a step grade, it will be rear biased and will split the power and drop off around 50mph. I wish my MDX had a 50/50 split option and ability to turn off vectoring completely. My tire wear is fast compared to others and have had the rear kick out on icy corners. I've gotten used to just not accelerating on tight turns when that happens.

      The new ones kinda suck bc you cannot fully disable traction control, traction control off in the 07 MDX, she'll send 90% to the rear and drift in the snow.

      We almost bought an MDX, but we wanted to be able to tow an enclosed trailer, about 5000 lbs in winter conditions. We borrowed an MDX for a test drive and without the trailer I was really impressed with how the system performed in the wet and in the snow. It was also plenty of fun if you wanted to play around in slippery conditions with its torque vectoring controlling yaw and allowing mild oversteer. Any time we accelerated the SH-AWD seamlessly kicked in and cornering with any throttle and the torque vectoring would seamlessly kick in and provide very effective cornering, even in slippery conditions. It also did a fantastic job at making sure any tire with grip got torque for when trying to move in unequal slippery conditions. Even experimenting with ice under any 3 tires and pavement under only 1 tire, it was able to transfer power to any tire (including a single front tire by applying the front brake for the wheel on ice) very well. I was all set to part with my cash...


      Unfortunately when we hooked up the trailer (with only half a load too) we found that while cruising on the highway at 60-70 mph that the front tires kept losing traction every time we hit a bit of slush or snow. Once they did the SH-AWD system would start to engage the rear wheels, but only after slipping first at these higher speeds. At highway speeds it really wants to be a front wheel drive. That was bad enough with the MDX providing a very "front wheel drive feel", and "surging" in and out of AWD, but after about 15 minutes of highway cruising with the SH-AWD kicking in over and over to keep the speed up, an SH-AWD over temperature warning popped up on the gauge cluster (and the temperature outside was something like -5°C too). Once this happened the system reverted to a fully front wheel drive vehicle and now it sucked totally at even trying to maintain speed in the no more than 1.5 inches of snow that fell that afternoon with the front tires spinning and losing traction constantly. I suppose it is possible this particular 2014 MDX was defective and it did not have snow tires, but I did find comments on online forums where other people experienced the same problem when towing in slippery conditions with their MDX too. In addition to the poor winter towing performance I was also concerned that we might end up burning out the SH-AWD clutches by towing in the winter so we decided against the MDX.


      Later, in essentially the same conditions, we tested a slightly older 2007 Lexus GX470 (ended up buying it too) with its old fashioned full time 4wd system, also equipped with all season SUV tires. For towing the trailer it was much more consistent than the MDX. If required you can lock the center differential, but even with it open, it worked great for towing. Also when the traction gets bad and unequal, the GX470 does a great job using the A-Trac system to transfer power to tires with grip (easily passing the same 3 wheel on ice 1 wheel on pavement tests that the MDX also passed, with ease). The GX470 doesn't have the very cool torque vectoring the MDX has and you can definitely feel the difference though. The GX470 does like to oversteer a bit if you push it, but it won't let you play too much before the computer kicks in and straightens you out (unless you disable the system).


      Another useful feature for towing that the GX470 has that the MDX doesn't is auto-leveling air suspension. No matter how much load the GX470 has in the rear or how heavy the trailer's tongue weighs, the air bags automatically inflate and bring the vehicle to a level stance. It also has adjustable damping for the shock absorbers so heavy loads can be stiffened up to provide a very stable ride.


      Ultimately the GX470 behaves more like a very luxurious, comfortable truck with an incredible sound system and a heavy duty, "torquey", low rpm engine, and a truck-like drivetrain that is also very capable off-road, while the MDX behaves more like a moderately luxurious, semi-sporty station wagon with a powerful, high revving engine and a light duty AWD system. As a people mover and daily driver I'd probably prefer the MDX, but for an all around utility vehicle that is also extremely luxurious and comfortable, especially for long distance highway cruising (with or without a trailer), the GX470 is tough to beat.

      remember with sh-awd if you get stuck in snow when you park, turn off traction control so you can get enough torque to blast out of the snow. Dont ask how I know

      NEVER buy car with Forced Lighting. Always verify that ALL lights can be turned off during the daytime. If you don't do this your resale value is terrible. I sold a used car recently, most of the people that came to look at it would not buy the car because the Daytime Running Lights (DRL) could not be turned off. You have been warned. Toyota has DRL Off on the light switch.
