Drivers that live in regions with heavy seasonal weather like rain and snow will find that all-wheel drive provides better traction on roads affected by inclement weather. All-wheel drive can send power to both the front and rear axle unlike vehicles with front- or rear-wheel-drive drivetrains.
An AWD vehicle typically gets fewer mpg of gasoline than a comparable front- or rear-wheel-drive vehicle, so it pays to shop for a model that gets top fuel economy.
AWD vs. FWD, Which Is Better In Ice and Snow? All-wheel-drive is usually better in ice and snow because it engages all four wheels to get started and to keep you moving. With modern traction and stability controls, an all-wheel-drive vehicle can handle most snow and ice conditions.
Even with a ton of power, it's not easy to drift AWD cars. New AWD cars like the Ford Focus RS and Mercedes E63 even come with a drift mode that sends more power to the rear wheels.
Is All-Wheel Drive or Four-Wheel Drive Better For Snow? All-wheel-drive systems deliver power to all four wheels at the same time, or they automatically engage torque to all four wheels when needed. That's why all-wheel drive is best for driving on snowy and icy roads.
Here's a rundown of four of the most well-engineered systems on the market today.
- Subaru Symmetrical All-Wheel Drive. All-wheel-drive has always been synonymous with Subaru.
- Audi quattro.
- Acura Super Handling All-Wheel Drive (SH-AWD)
- Ford's Intelligent All-Wheel Drive.

When it comes to handling, all-wheel drive is overrated (not to mention heavy and gas-sucking), especially in foul weather. At the same time AWD doesn't improve your handling, it does offer an overly optimistic sense of available traction, and it provides the potential to be going so much faster when you need to stop.
Most modern all-wheel-drive vehicles do not allow the driver to disable all-wheel drive and will permanently send some power to every wheel regardless of driving conditions.
AWD is fine for most normal snow conditions or for light-duty, off-pavement excursions on dirt roads or slippery surfaces. If you'll be driving in severe snow or true off-road situations, or if you're interested in pursuing off-roading as a hobby, you should opt for a vehicle with 4WD and lots of ground clearance.
It's a simpler system, so it's easier and less expensive to maintain. It's lighter, so front-wheel drive cars tend to have better fuel economy than all-wheel drive vehicles. But front-wheel drive does have better traction when it comes to climbing hills, since all the weight of the engine is over those front wheels.
What's the difference between AWD and 4WD? There is very little difference in the mechanicals of all- and four-wheel drive. All-wheel drive describes vehicles that have a four-wheel drive system designed to maximise road traction, for example on slippery roads.
Another important example of the increased level of safety of an All-Wheel Drive car compared to a Rear-Wheel Drive car is when cornering under drive power. Meaning that the best AWD car will lose sideways grip at much higher cornering forces than the best RWD car.
Our simple conclusion is that all-wheel drive and four-wheel drive systems are one of the most valuable safety systems you can purchase. That is true whether you buy a family crossover, SUV, truck, or car. Powering all four wheels reduces your chances of dying while driving that car in real-world crashes.
While many people think that all-wheel drive is enough to take on dangerous ice and snow, there is almost no difference between AWD-equipped vehicles and common front-wheel drive cars when it comes to cornering, braking and handling in winter weather.
The short answer is yes, an all-wheel drive vehicle is more expensive to maintain for one simple reason: an AWD vehicle has more components. According to EPA estimates, the AWD Rogue will cost around $150 more a year in fuel, if driving 15,000 miles a year.
The simple point is this: for maximum winter driving performance a 4WD or AWD vehicle should have winter tires installed. Only winter tires can provide the depth of tread and soft rubber compounds necessary to grip the ice and snow.
How to Drive in Snow With an AWD
- Assess the driving conditions. AWD helps in the snow, but it does not help on ice.
- Accelerate slowly. If you feel the tires slip because there is ice, continue to drive slowly until you feel the tires gain traction.
- Be cautious when driving at high speeds.
- Avoid sudden stops.
Front-wheel drive has worse acceleration than rear-wheel drive, which is why most sporty and race cars use rear-wheel drive. With all the weight up front, front-wheel drive can make handling more difficult. CV joints/boots in FWD vehicles tend to wear out sooner than rear-wheel drive vehicles.
The method is different, yes. In front wheel drive drifting the racer uses the pull up emergency brake for short intervals to cause the loss of rear wheel traction by locking the rear brakes. To do it, you should accelerate to your ideal speed.
The disadvantage of a RWD vehicle are that they do not perform well in poor weather conditions such as rain or snow because they are more prone to loss of traction on slick roads.
On an AWD vehicle or one with a conventional four-wheel-drive system, all four tires would ideally be replaced at the same time so they all have the same amount of traction as well as the same diameter. The best approach, though, is to replace all four if the tread on the old tires is significantly worn.
Front-wheel drive reduces weight, decreases production costs, and improves fuel economy compared to a rear-wheel-drive system. It also improves traction since the weight of the engine and transmission is directly over the driven wheels.
All-wheel-drive and four-wheel-drive systems are generally more expensive to insure than front-wheel-drive systems. The reason for this extra cost is that all-wheel-drive systems have more moving parts, which means more opportunities for something to need repair on your vehicle.
