The drive mode personalization features on a number of our INFINITI models, including the 2021 INFINITI Q50 and the 2020 INFINITI QX60, let you tailor your drive to the road and your particular tastes. With modifications to engine and gearbox outputs, efficiency ratios, steering ratios, and force settings, the adjustable options improve vehicle performance.
The unrivaled Snow Mode from INFINITI is one of these options. By adjusting the throttle to account for the wintery circumstances for smoother performance and more safety, the assistive technology alters your engine output when you choose this option in snowy conditions. This reduces tire spin on slick roads. Your INFINITI will be more responsive in the snow and have a softer throttle profile in this setting.
The AWD on your car also benefits from INFINITI’s Snow Mode, which closely monitors wheel spin sensors and modifies power delivery to enhance handling.

First of all, you should be aware that the Q50 I was testing had snow tires and had all-wheel drive. A computer can keep the car aligned if the tires start to spin out of control or can power other tires if it detects tire slide. That’s what Subaru has been doing for a while. The snow setting, however, goes far further than that.
To the right of the driver is a tiny drive mode button that must be pressed to activate it. To activate Snow mode, you need to tap back on it twice. (You may also alter the driving mechanics using Eco mode, Sport mode, and a few other settings.)
I don’t need to speak with the engineers to understand how it functions in practice. The Q50, which is the opposite of sport mode, knows when to back off on the throttle when you accelerate. I never slipped on the pavement while driving in a winter storm on a route where I couldn’t even see the lane markings since the Q50 wasn’t moving quickly (even though with a 400 horsepower engine it certainly could have). This vehicle worked well in the snow setting; it’s like a nanny for the snow.
Another notable technological element was how the AWD and snow setting constantly monitored tire spin. I was amazed by the car’s ability to keep its bearings and stay in the middle of the road after multiple turns on snow-covered side streets. When it comes to car technology, this is what we all actually want: driver aid technologies that are discreet until you need them.
Because the Q50 was monitoring my driving and assisted me in avoiding a spin-out on a subsequent journey in much heavier snow, I never had to focus too much on winter driving advice (steering into a spin-out, not speeding or over braking).

Ok, so I don’t know whether this fits to our question, but I discovered this on an OLD thread from a forum from a few years back that was referencing a few years prior to that. It might give you an idea, though:
A few years back, Nissan sent me this… notice bold print below:
In comparison to conventional all-wheel drive systems, the ATTESA system is built for smooth starts, improved fuel efficiency, and higher traction and maneuverability on icy roads, with no compromise to rear-wheel drive performance attributes on dry roads.
The innovative torque split control technique of the system automatically distributes the best torque to the wheels based on the driving and road conditions. It has excellent cornering performance, comparable to that of a sports car, because the front and rear wheels receive the ideal distribution of torque (from approximately 0:100 up to 50:50).
Wheel spin, throttle position, and vehicle speed are continuously monitored by system sensors (at all four wheels). The G35 behaves and feels like the acclaimed rear-wheel drive G35 sedan when the road conditions don’t call for AWD, and the system is capable of directing up to 100% of the power to the rear wheels. Comparatively, the leading competitive AWD systems with center differential transfer systems only allow for 50% (Audi A4 Quattro), 60% (Mercedes C-class 4-matic), or 62 % of available power to be sent to the rear wheels (BMW 330xi). Thus, there is little trade-off between the performance and handling feel of rear-wheel drive and the G35.
The ATTESA system modifies the front-to-rear torque distribution from a standing start, adding 25% to the front wheels for a stronger start. The system then swiftly modifies the torque distribution as required, increasing the front drive percentage up to 50% or delivering up to 100% of the torque to the rear wheels, depending on the situation.
The ATTESA technology can recognize traction needs as a corner is being taken and respond appropriately. To improve stability and traction, the device may switch toque between the front and rear wheels with a millisecond response time. Under typical driving circumstances, the system performs nearly identically to any rear-wheel drive vehicle when turning into a corner. Nearly all of the torque is in the back. Once in the bend, the system is able to shift the drive torque that the rear wheels are unable to handle to the front wheels. This produces exceptional cornering ability akin to that of a sports vehicle. For a smooth acceleration out of the bend, torque can be quickly transferred based on the rear wheels’ wheel spin ratio, which can range from 50:50 to 0:100.
The G35 AWD system’s inclusion of the Snow-Mode function, which lowers throttle sensitivity and sets the initial torque distribution at 50:50 to prevent wheel spin for smooth starts on snowy roads, is another distinctive aspect of the design. The Snow-Mode function enables the central computer processing system to resume control at speeds more than 12 mph, continuously monitoring the traction conditions, and adjusting the torque distribution as necessary.
What changes a car makes in snow mode?
Even though many Australians may never have to deal with the difficulties of driving on snow-covered roads, those who do enjoy going on winter excursions will benefit greatly from Toyota Snow Mode. By lowering the throttle input, reducing power, boosting traction control, and delivering more moderate braking power, this drive mode offers improved stability. Together, these factors assist keep the wheels from spinning out on slippery roads, giving the driver more control. an a
Which type of vehicle is ideal for driving over snow?
The greatest alternative for driving on snow or in icy situations is all-wheel drive (AWD). The operation of AWD is the cause. All-wheel-drive systems deliver force to each of the four wheels simultaneously. When necessary, these mechanisms activate automatically.
Does snow mode use all four wheels?
According to Edmunds, cold weather causes the surface of the roads to change quickly. Roads can become covered with ice and snow throughout the winter, which makes them very slick. Driving on these slick conditions requires traction, which is essential. When necessary, all-wheel-drive systems automatically apply torque to all four wheels or deliver power to all four wheels simultaneously. All-wheel drive is therefore recommended for navigating icy and snowy routes. A vehicle with all-wheel drive eliminates the need for driver intuition.
According to The Globe and Mail, four-wheel drive is a good choice for traveling in thicker snow or in more severe winter weather. For instance, four-wheel drive may perform better in certain situations if you come across a snowdrift or an ice hill.
Consider which is better for your needs rather than seeing four-wheel drive and all-wheel drive as competitors. Where does your tire contact the snow when you’re driving, says Auto Sock? Four-wheel drive can be more practical for your requirements if you reside on a back road that isn’t routinely plowed. All-wheel drive can be a better option for you if you reside in a city where the roads are often plowed but the weather is still treacherous.
When it rains, does snow mode help?
I hope my query isn’t silly because I’ve never owned an AWD. Is it advantageous to utilize Snow Mode when it’s raining? Snowy and slick roads are mentioned in the manual, however it’s unclear whether this poses any unexpected control concerns.
Personally, I don’t believe that snow mode is necessary in rain alone. Snow mode offers 50% distribution to the front and back during starts, which you really don’t need in the rain. This is a big benefit for snow mode. All of the settings are still AWD Auto, albeit in my opinion Comfort mode would be more appropriate for wet conditions. I think you get 30% in the back and 70% up front. You receive very little in the back when in ECO.
How quickly can a car go in snow mode?
I just wanted to ask a quick question about driving in Snow Mode with AD1 and speed. I’m traveling down Interstate 80 in Northern California toward the Sierra Nevada Mountains, where snowy conditions are predicted. Is there a speed limit when using AD1’s Snow Mode? Now that I am aware of the fact that my speed will probably depend on the road’s conditions, I only wanted to know if the AD1 system had a set maximum speed. I once owned a Ford Bronco (yup, going old school with a car that had a “true” 4×4 system), and I recall that it was advised under 4-Wheel Drive High to keep the speed down to 45 mph to prevent tire damage.
No, the Snow mode has no speed limit. You can travel at any speed. In order to reduce tire sliding and better balance the power output across the 4 wheels, snow mode will put you in second gear as soon as you leave a stop.
I’ve tried driving in snow mode on the interstate, but I couldn’t tell the difference between it and auto. Only when the roads are covered with a new coating of snow do I find myself employing Snow mode in the city. Otherwise, I Auto performs admirably.
In snow, is sport mode preferable?
Use the low-ratio mode on your automatic or four-wheel-drive vehicle when driving in the snow. Useless in sport mode.
However, if your vehicle is rear-wheel drive, fill a couple sandbags and set them over the rear axle in the trunk. RWD cars have a tendency to slide more in snow, thus this will assist improve traction and steady the vehicle. If you do skid, gaze in the direction you wish to go and point the tires in that direction rather than turning into the skid. Release the brakes gradually while applying little pressure to the accelerator.
Additionally, all-wheel drive is not a miracle solution to the snow. Although having snow tires will assist you get moving and stay moving in deep snow, this is preferable than depending on the type of drive you have.
When there are a few inches of snow, front-wheel drive is beneficial. According to the National Motorists Association, “When it snows, front-wheel drive is significantly superior to rear-wheel drive. Unless the snow is extremely deep, in which case the lack of ground clearance will more than anything else cause you to get stranded, you should be able to make it to work with a good pair of all-season or snow tires.”
You can navigate even deeper snow with a 4×4. Unless the snow is exceptionally heavy, you shouldn’t encounter any issues with decent snow tires. For a 4×4, even unplowed roads are still a possibility.
Is AWD preferable to snow mode?
While many people mistakenly believe that AWD is sufficient to handle treacherous ice and snow, there is essentially no difference between vehicles with AWD and regular cars when it comes to steering, braking, and handling in wintery conditions.

People who believe AWD and four-wheel drive (commonly abbreviated as 4WD or 4X4) systems are fundamentally the same thing are surprised by this. They don’t are. A
4WD systems deliver power to all four wheels equally, independent of their traction, in contrast to AWD systems’ flexible nature. One of the main distinctions between AWD and 4WD is this “always-on” power. Contrary to popular belief, tires alone—not even 4WD—create traction. 4WD could not be sufficient to maintain control of the vehicle if the tires are traction-limited (either by design or due to severe wear).
