Dynamic Torque Vectoring AWD with Driveline Disconnect addresses some of the issues with existing Toyota all-wheel-drive models. The RAV4 TRD Off-Road, Adventure, and Limited, as well as the Highlander Limited and Highlander Platinum, all come standard with this rather complex technology. The all-wheel-drive transfer case is included into the transmission, just like on the simpler system, but there is a dog clutch between it and the driveshaft that may entirely disengage when only front-wheel drive is required, lowering system drag.
A second dog clutch placed in-between the driveshaft and the rear differential increases the system’s adaptability in properly metering out power. Additionally, the differential’s own clutch packs offer active torque vectoring. When one wheel loses traction and begins to spin, the clutches engage, delivering power to the other wheel. The system is even better at maintaining forward motion because it uses less brake-based traction control.
Similar all-wheel-drive systems with a driveline disconnect are used by the Toyota Highlander L, LE, and XLE; however, these models forgo the dynamic torque vectoring component in favor of a less complex open differential that employs traction control to prevent wheelspin.

What drives the RAV 4 AWD?
The first thing to keep in mind if you’re looking at an all-wheel drive RAV4 is that you must avoid the base Icon model, which is only offered with the 2WD petrol engine.
In the new RAV4 AWD Hybrid, a second, rear-mounted electric motor is combined with the Toyota hybrid engine and conventional motor to power the rear wheels.
Due to the ability of the two motors to distribute torque among all four wheels, traction and stability are enhanced. The All-Wheel Drive with Intelligence technology also monitors road conditions and modifies the torque distribution for the best possible handling, traction, and efficiency (AWD-i).
The RAV4’s control system distributes the majority of the torque to the front wheels under typical driving and road conditions, providing the most economical and fuel-efficient choice. However, the system will use the rear motor to give the precise amount of required torque if it senses the need for additional traction at the rear, such as if the front wheels are sliding, for the best stability and grip.
The technology aims to combine high levels of vehicle control and safety with fuel efficiency.
The Toyota RAV4’s clever technology allows it to send up to 60% of its power through the rear motor, enabling hill starts or driving on wet, snowy, icy, or other surfaces with limited traction much better and more manageable.
In sport mode, the E-Four Hybrid can change how much torque is distributed between the axles to provide a livelier driving experience.
With a braked towing capability of 1650 KG, the Hybrid AWD-I also offers more robust towing capabilities.
The RAV4 always has all-wheel drive.
Every Toyota RAV4 variant offers all-wheel drive, which comes standard on the luxurious Adventure model. Nevertheless, the kind of all-wheel-drive system you get will depend on the model you choose. Learn more about your Toyota RAV4 AWD options from the professionals below at Earl Stewart Toyota!
What drives the AWD system in a Toyota?
Toyota Hybrid All-Wheel Drive In this hybrid AWD system, the rear wheels are driven by an electric motor at the back of the vehicle when the front wheels start to slide. The impact on fuel economy is limited because there is no mechanical link between the front and rear axles.
What drives the RAV4 Prime AWD?
The RAV4 Prime’s dynamic crossover SUV is propelled by an electronic on-demand all-wheel drive (AWD) technology, which was first used on the RAV4 Hybrid. When necessary, such during acceleration and starting up, a second rear-mounted electric motor powers the rear wheels. This is how it works. Additionally, this system aids the RAV4 Prime in gaining a better hold on the road when the traction is less than optimum.
This AWD system helps you better climb those mountainous locations when you take the RAV4 Prime off the paved highways and onto the unpaved roads leading to your preferred weekend getaway property. The RAV4 Prime also provides a unique Trail driving mode that, in order to prevent you from becoming stuck in the mud, will brake a wheel that is spinning out and send torque to the wheel that is firmly anchored.
Other RAV4 Prime off-roading features
In addition, the 2021 RAV4 Prime provides paddle shifters as an optional feature that enable drivers to “downshift to improve regenerative braking to help give you even more control when driving on hills.” Predictive Efficient Drive, another feature of the RAV4 Prime, learns your driving patterns and uses the optional navigation system to essentially read the route so that it can optimize the hybrid battery’s charging and discharging based on the driving conditions at the moment. It even retains details of well-traveled roads!
What drives the RAV4 AWD in 2021?
The Toyota RAV4 was never intended to compete with its Hilux and Land Cruiser brothers’ off-road prowess when it was first introduced in 1994. Recreational Active Vehicle with Four-Wheel Drive makes up the model name. a statement that characterizes the RAV4 as a lifestyle car with some all-wheel drive performance as an added bonus.
The sophistication of the Toyota RAV4’s chassis is undervalued if it is deemed to be an SUV that is only suitable for urban environments. Two separate optional all-wheel drive systems give it its off-road capability. These systems are intended to keep you safe, in control, and mobile in situations where a conventional car would probably be unable to operate.
Let’s examine these two systems in more detail. The most well-known E-Four electrical system is featured in all-wheel drive RAV4 Hybrid cars and is introduced first. The mechanical system is then introduced, which is present in conventional all-wheel drive petrol and diesel variants.
Toyota RAV4 Hybrid E-Four all-wheel drive
Models with E-Four all-wheel drive use a second, rear-mounted electric motor in addition to the well-known Toyota Hybrid engine and motor to power the front wheels. By distributing torque throughout all four wheels, this enhances traction and stability.
The front wheels receive all of the car’s power when it is being driven normally since they are the most fuel-efficient place for the energy to go. To determine the best torque distribution, the RAV4’s electronic control unit continuously measures information such as travel speed, accelerator angle, and wheel speed. It orders the rear motor to transfer a specific amount of torque to the rear wheels to make up the shortage if it notices that greater torque is needed at the rear (for example, if the front wheels are slipping).
The rear axle can receive up to 60% of the overall power of the vehicle. Therefore, having some torque transferred to the rear wheels makes it simpler to accelerate in a controlled manner when you’re pushing away, moving up a hill, or driving on a surface with minimal traction. To provide a livelier, more secure driving experience, the E-Four technology may also distribute torque across both axles.
If you choose a RAV4 Hybrid with E-Four all-wheel drive, your towing capability more than doubles. Models with front-wheel drive can pull up to 800 kg, while those with E-Four all-wheel drive can pull 1,650 kg.
Toyota AWD is it always on?
It can be a little perplexing with Toyota’s three All-Wheel Drive (AWD) systems and two 4-Wheel Drive (4WD) systems. The Land Cruiser and 4Runner Limited models use what we refer to as “full-time 4WD,” whereas Toyota trucks use what is known as “part-time 4WD.”
Does the RAV4 AWD handle snow well?
The Toyota RAV4 has an All-Wheel-Drive option, over 8 inches of ground clearance, and a slew of traction-controlling technologies. It is therefore perfect for cold and snowy trips.
A 2.5-liter four-cylinder engine with an eight-speed transmission and 203 horsepower is also included with the RAV4.
Is Toyota AWD trustworthy?
Another AWD SUV that Consumer Reports recommends is the Toyota Venza from 2021. It received a rating of four out of five for projected reliability from the organization, which is just shy of perfection. Additionally, the AWD SUV received a forecasted four out of five owner satisfaction rating. Even if that rating isn’t ideal, Consumer Reports data reveals that 78 percent of current Venza owners would repurchase the AWD SUV.
On the other side, the 2021 Ford Edge had a forecasted rating of three out of five for owner satisfaction. The good news is that Consumer Reports also gave it an overall road test score of 84 and a predicted dependability rating of four out of five. What is the price of all-wheel drive? An AWD Ford Edge will cost you an extra $2,000, on average.
Can the RAV4 Prime handle snow?
I primarily focused on kid passenger and vehicle safety in my RAV4 Prime Review. After a few months of driving, I expanded the review with a few loves and dislikes in the preceding long-term update. After seven months, I’ll talk about some of my favorite and least favorite aspects in this update, mostly in relation to my winter driving experience. In full openness, I switched the original Michelin CrossClimate2 all-weather tires’ Yokohama Avid GT rubber for 3 Peak Mountain Snow Flake-rated tires. I haven’t had any problems with traction yet in the rain, snow, or on slick roads.
Fair enough, the worst I’ve seen is a few inches of snow on an unplowed gravel road, packed snow on paved roads, and glare ice on driveways and roads. Although they generate a little more noise than my Highlander Hybrid, the antilock braking and traction control systems appear to be rather effective. The rear motor appears to always be powering the rear axle at launch, and it appears to function consistently in low traction situations, as best I can determine from the on-screen power flow meters. Officially, the ground clearance is 8.3, but I measured nearly 9.5 inches of clearance down the centerline of the car at 37 psi and stock P235/55R19 tires. However, Toyota advises against using common tire chains with this tire size.
The RAV4 Prime handles slick conditions well. In fact, some YouTubers have films that demonstrate some fairly incredible performance on snowy roads as well as off-road. However, the Prime’s Electronic On-Demand AWD system, like the RAV4 Hybrid’s, depends on traction control to transfer power from one wheel to another on the same axle. When compared to vehicles like the RAV4 Adventure/TRD and other Toyota models with Dynamic Torque Vectoring, which can move more power (and send it more quickly) from one axle to the other, this type of reactive system is very constrained. On the plus side, the Prime does have a little electric back motor that, even at slow speeds or when starting from a standstill, can generate a reasonable 90 ft-lb of torque. As a result, there is no need for a center differential or transmission, and the back wheels receive immediate power.
Even a 53 HP rear motor feels more than adequate for light off-roading and low traction situations like moderate snow and ice. Additionally, a “Trail mode appears to allow the gas engine to start more easily and also permits considerably greater wheel spin, preventing the throttle reduction and traction control from engaging too soon. This could come in handy in a number different low traction scenarios, particularly if you need to “dig” or “rock” the car back and forth while experiencing wheelspin to regain traction. Of course, there is a button in the middle stack that allows you to completely turn off traction control in any mode. Avoid driving in most adverse weather conditions on roads “Put the traction control system in the trail mode.
Over 75% of the time, I drive in the normal EV mode. The remaining 25% of the time, especially when I’m on the interstate, I convert to HV mode if I need additional power or more cabin heat from the gas engine. When overnight charging for an EV range of 50+ miles was sufficient to handle the majority of my everyday driving this summer, I was able to go more than 3000 miles on one tank of gas over the course of a few months. We also utilized the gas engine on a few lengthy road journeys, achieving 31 to 35 mpg in HV at 70 mph highway speeds. In hybrid HV mode, it’s not difficult to achieve over 40 mpg in town during nice weather. When temperatures are harsh and need regular use of the air conditioner or heater, fuel economy and EV range will, of course, be much lower.
I’ve reduced my list of advantages and disadvantages to just the important ones now that I’ve driven far over 5000 miles and have some experience with winter driving.
Likes:
- Drivetrain. Buy it for this reason. Power, range, and adaptability. In perfect summertime driving conditions, I reached a max of 3.5 miles per hour and 55 miles of estimated EV range. Since then, more rash driving and below-freezing weather have caused that to fall to a still acceptable 3.0 mi/kwHr and 43 EV miles.
- Almost always, EV mode is EV. The internal combustion engine seems to start up far more regularly in other PHEVs I’ve driven than I’d anticipate. The R4P keeps the EV mode pretty much intact at temperatures below 20 degrees. The gas engine might start up now and then, but not frequently.
- Reliability/Quality. There are none.
- Alerts for rear cross traffic and blind spots. Particularly if you have novice teen drivers, I still really like these!
- Unexpectedly helpful features include the automatic parking brake, Heads Up Display, and birds-eye view camera.
- Although the heated steering wheel works well for me, purchasers should be aware that the top and bottom are not heated.
- Even on extremely hot and humid days throughout the summer, the air conditioning proved quite effective.
- Style. I must say that I adore the accent lighting and XSE trim wheels. They stand out among the many different RAV4 trims and have a striking appearance.
Meh:
- Seat heating and ventilation. These function, but “Even at the highest settings, just OK. Sure, it’s better than nothing, but it’s not quite as efficient as any other car I’ve driven recently.
- Sound of a heat pump. It starts making a very loud foghorn noise for a few seconds when the temperature is below about 40F. I hear that a software remedy for a problem with the refrigerant fluid condenser is already available in other nations. It’s really not a huge deal.
- Although lane keep assist works effectively, mastering it will help you avoid stumbling into “instead of holding the center like other systems, it exhibits ping-pong behavior, wobbling between the lines.
- With 4 gallons of gas left, the gas gauge indicates empty.
- Particularly the back hatch button, which I wish had been included to the array of buttons under the HVAC controls in the center stack, the buttons on the bottom left of the dash may be easier to see or reach.
- Android Auto occasionally disconnects. The fact that I don’t have this issue with our second car makes me wonder if it is a vehicle-related issue.
- App for Android. varies from inadequate to broken and has been back for months. Late 2021 upgrades seem to have fixed the most of the major problems and added remote lock/unlock to the Android version. I’m delighted to report that the climate control remote start now functions mainly.
Dislikes:
- Low-quality heat in EV mode. By turning down the gas engine as much as feasible, economy and EV operation in cold weather come at a cost. Once it is well below freezing, the efficient heat pump can no longer keep up. Fortunately, the gas engine may start at roughly 14 F (-10 C) to warm the interior (though not using remote start). Once the car is running and you are inside, you can use the front defroster, the HV or HV/CHG hold mode, or the front defroster to try to push the engine to heat up. This offers adequate warmth, similar to a hybrid or standard gas vehicle. (For advice, see below)
- ceiling switches and doors. Unexpectedly, the lack of backlights is a major annoyance. I found the driver’s side door to be so problematic that I purchased a drop-in replacement with backlights on Amazon. This was just inexpensive because Toyota includes comparable backlights in a lot of its other mid-range and economical cars. According to reports, a few door and overhead switches for 2022 vehicles with minimal minor upgrades will be lighted.
- recurring warning Chimes can be inconvenient, such as the incessant icy road warning that sounds whenever it is cold even if there is no sign of snow or ice.
I realize that these complaints are minor, but they might be useful to other customers. At least in my opinion, the benefits greatly exceed these comparatively modest drawbacks. The android app was by far my biggest gripe, but thanks to recent updates, even it is now tolerable. I have no regrets about adding the RAV4 Prime to our fleet because I genuinely love owning and operating it. Additionally, when it comes to child safety seat demonstrations, the seat arrangement mirrors one of the most popular vehicles and is characteristic of many well-known compact SUVs. The R4P is very practical and a good bargain at MSRP thanks to its power, economy, AWD, and cargo space. The additional cost of the excellent powertrain is largely compensated by the entire federal EV tax credit.
Due to supply chain challenges that affect the entire industry, I am aware that they are still difficult to find and that many dealers are charging significantly more than the suggested retail price. Although top-tier trims have a lot of luxury-level features, a PHEV in this price range is unquestionably not in the luxury-class. Buyers should be aware that the $7500 federal tax credit for Toyota may phase out by the end of 2022 and that, if approved into law, congressional bill ideas could lower it (perhaps to $4000).
Update: Numerous owners have expressed their complaints regarding inadequate or subpar heating in numerous online communities. From the comments below, I’m pasting a few of my advice for extremely cold weather:
- Pre-start the car as frequently as possible using the remote temperature control with the Max Heat setting if it is available (85F). It will help, even if the car doesn’t warm up as much as you had hoped. This may aid in the heat exchanger’s interior defrosting as well.
- Put on layers of clothing and use the seat and steering wheel heaters, if available, for maximum efficiency when operating in EV mode as much as feasible.
- Increased cabin heating and windshield defrosting
- Make sure the A/C is on and the recirculated air setting is off for defrosting the inside of the windshield.
- Turning on the front defrost may compel the gas engine to run if you require more heat than the energy-efficient heat pump in EV mode can deliver. Pressing the EV/HV mode button on the center console to activate HV mode for hybrid operation is the best approach to start the gas engine. Press and hold the EV/HV mode to enter CHG mode, which will compel the gas engine to run continuously in HV mode. Once the interior is sufficiently warm, switch back to HV mode because there will be a significant loss in fuel economy in this mode.
