Introduction
One of the most significant decisions when buying a new car is choosing the drive train. The drive train is how the power from the engine gets to the wheels and significantly impacts how the car handles, accelerates and performs in different conditions. Two of the most common types of drive train are AWD vs RWD All-Wheel Drive (AWD) and Rear-Wheel Drive (RWD). Each has its pros and cons, and understanding these will help you make the right decision for you, your driving style and the conditions you’ll be driving in.
In this guide, we’ll break down the differences between AWD vs RWD and which might be better for different drivers. By the end, you’ll know which drive train will give you the performance, handling and safety you want.
Drive train
Before we get into All-Wheel Drive (AWD) and Rear-Wheel Drive (RWD), let’s first understand what a drive train is and how it affects your vehicle. The drive train is responsible for transferring power from the engine to the wheels. How this power is distributed significantly impacts how a car handles, accelerates and drives in different conditions.
What is a Drive train?
A drive train is a system of components that delivers power from the engine to the wheels to move the car forward or backwards. It determines how the power gets to the road, and different drive trains are for various driving styles and needs.
The drive train connects the engine, which generates power to the wheels, which deliver that power to the road. It includes:
- Transmission: This system controls the power sent to the wheels and adjusts according to speed and load demands.
- Driveshaft: In cars with the engine at the front and power going to the rear, the driveshaft carries the rotational energy to the rear axle.
- Differential: This is a critical part of the drive train that allows wheels on the same axle to rotate at different speeds, applicable during cornering.
Characteristics
Different types of drive trains distribute engine power in various ways, each with unique driving characteristics:
- Front-Wheel Drive (FWD): The engine sends power to the front wheels in this setup. It’s common in most passenger cars because it’s simple and efficient. FWD cars have good traction in wet or snowy conditions because the engine’s weight is over the drive wheels.
- Rear-Wheel Drive (RWD): The power is sent to the rear wheel in RWDs. This setup has balanced weight distribution and better acceleration and handling in performance cars. However, it struggles with traction in slippery conditions because the rear wheels have less grip on slick surfaces.
- All-Wheel Drive (AWD): AWD sends power to all four wheels, full-time or part-time, for better traction in wet, snowy and off-road conditions.
- Four-Wheel Drive (4WD): Often mistaken as AWD, 4WD means systems that the driver can engage or disengage, usually for off-road driving. In 4WD, power is distributed evenly to all four wheels, but it’s primarily used in rugged terrain and not everyday driving.
Your drive train choice can affect your driving experience, from handling and acceleration to traction and stability in different conditions.
What is All-Wheel Drive (AWD)?
All-wheel drive (AWD) is a drive train that powers all four wheels simultaneously or dynamically distributes power between the front and rear axles, depending on the driving conditions. AWD is designed to improve traction and stability in various driving environments, which is perfect for drivers who encounter rain, snow, ice, or even light off-road situations.
AWD systems are designed to monitor the vehicle’s grip on the road continuously. When the system detects a loss of traction – such as when driving on a slippery or uneven surface – it sends power to the wheels with the most grip. This real-time ability to adjust power between the wheels makes AWD an excellent option for drivers needing a versatile all-weather vehicle.
Types of All-Wheel Drive Systems
There are two types of AWD systems: full-time AWD and part-time AWD. Both send power to all four wheels, but they work differently.
Full-Time AWD
The car always sends power to all four wheels in a full-time AWD system. So, the vehicle continuously distributes between the front and rear wheels, and the drive train adjusts the amount of torque each set of wheels gets based on the road conditions. Full-time AWD cars use a centre differential or viscous coupling to allow the front and rear axles to rotate at different speeds required for smooth cornering.
Full-Time AWD:
- Power to All Wheels: Power is continuously sent to all four wheels, providing better handling and traction.
- Automatic: The system adjusts power between the front and rear axles as needed; no driver intervention is required.
- Stability: Full-time AWD provides stability under challenging conditions like wet, icy or unpaved roads.
- Fuel Efficiency: Since the system is always engaged, it can negatively impact fuel efficiency compared to part-time systems or RWD cars.
Pros:
- This is for drivers in areas with unpredictable weather or harsh winters.
- More confidence in poor conditions like heavy rain or snow.
- Traction and stability all the time.
Cons:
- Higher fuel consumption compared to part-time AWD or RWD.
- More wear on components can lead to higher maintenance costs over time.
Part-Time AWD
On the other hand, part-time AWDs operate in two-wheel drive mode (usually front-wheel drive) under normal driving conditions. The AWD system only engages when the car’s sensors detect a loss of traction, such as on wet or slippery roads. When slippage is detected, the system automatically engages AWD by sending power to the other wheels to regain control.
Part-Time AWD:
- Two-Wheel Drive in Normal Conditions: The car runs in front or rear wheel drive when driving in good conditions, improving fuel efficiency.
- Automatic Engagement: The system engages AWD when needed, usually when it detects loss of traction.
- Fuel Efficiency: Part-time AWD is more fuel efficient than full-time AWD since it only engages four-wheel drive when necessary.
Pros:
- It is more fuel efficient than full-time AWD since it only engages when needed.
- On-demand traction in poor road conditions.
- It is cheaper to run than full-time AWD systems.
Cons:
- Less consistent traction compared to full-time AWD.
- They may experience a slight delay in activation when conditions change suddenly.

How Does AWD Work?
AWD systems are complicated and designed to give the driver maximum traction, stability and handling in all conditions. Let’s break it down and how it works.
AWD System Parts
An AWD system has a few essential parts to distribute power to all 4 wheels:
- Differentials: These allow the wheels to rotate at different speeds when cornering. An AWD system will have at least 2 differentials (front and rear), and some systems have a centre differential to split power between the front and rear axles.
- Transfer Case: In some AWD setups, especially full-time AWD vehicles, a transfer case sends power from the transmission to both front and rear axles.
- Electronic Sensors and Clutches: Modern AWD systems have sensors that monitor wheel speed, throttle input, traction and road conditions. The system uses this data to decide how much power to send each wheel. Clutches in the system allow torque to be transferred between the front and rear wheels as needed.
Power Distribution
AWD systems monitor the road conditions and adjust power to the wheels accordingly. In full-time AWD, this is continuous; the system balances the torque between the front and rear axles based on how much grip each wheel has.
For example, an AWD system might send equal power to the front and rear wheels on a dry road. But if it detects a slippery surface, such as snow or ice, it might send more power to the rear wheels to stop the car from losing traction.
In part-time AWD systems, the car runs in two-wheel drive mode until slippage is detected. When slippage occurs, the system engages the AWD mode and sends power to all 4 wheels to help maintain stability and traction. The process is seamless and often invisible to the driver.
Benefits
- Better Traction: AWD systems have excellent traction on wet, icy or uneven surfaces, perfect for drivers who drive in varying conditions.
- Increased Safety: The ability to send power to all 4 wheels helps the car to be more stable and reduces the chance of skidding or losing control in bad weather.
- No Driver Input Required: Unlike traditional Four-Wheel Drive (4WD) systems, most AWD systems are automatic, so the driver doesn’t need to engage the system.
AWD in all Conditions
It is versatile, whether you’re on bitumen, dirt or snow.
In Wet Conditions, AWD sends power to all four wheels to help the car grip better on slippery surfaces. Reduces hydroplaning and improves overall control in the rain.
- In Snow and Ice: AWD’s ability to send power to the wheel with the most traction is super helpful in snow and ice. It compensates for wheel slippage, making driving easier in winter.
- On Dry Roads: While AWD is most useful in bad conditions, it can also help dry roads by sending power to all four wheels and improving overall stability, especially in corners.
What is Rear-Wheel Drive (RWD)?
Rear-wheel drive (RWD) is a drive train where the engine’s power only goes to the rear wheels, while the front wheels steer the car. Historically, RWD was the most common type of drive train in cars before front-wheel-drive systems came along. Today, RWD is associated with sports, performance, and trucks because of its balance, handling, and driving dynamics.
How does RWD work?
In a rear-wheel-drive system, power is generated by the engine and sent to the rear axle through a component called the driveshaft. The driveshaft connects the engine (usually at the front of the car) to the rear differential, which splits the power between the two rear wheels. The differential allows the wheels to turn at different speeds, which is essential for smooth cornering.
With RWD, the car’s weight is more balanced as the engine weight is at the front, and the power is at the rear. This separates steering and powering the vehicle between the front and rear wheels, creating a more dynamic driving experience.
Key Characteristics of RWD:
- Power to Rear Wheels: The rear wheels get all the power from the engine, while the front wheels focus on steering, making driving more engaging.
- Balanced Weight Distribution: Since the car’s weight is more evenly distributed between the front and rear, RWD cars tend to handle better on dry roads.
- Performance and Handling: Performance enthusiasts love RWD because it’s better for cornering and handling at high speeds, especially in performance cars.
- Acceleration Dynamics: When you accelerate, the weight shifts to the rear of the vehicle, which helps the rear tyres get more traction and provides stronger acceleration from a standstill on dry surfaces.
Benefits of RWD
- Better Handling: RWD cars handle and are more agile, especially in performance cars. Power and steering separated between the front and rear wheels means sharper corners and better response when dry.
- More Acceleration: Rear wheels get the engine’s power better, especially during acceleration, where the weight shifts to the rear and provides more traction. Best for RWD is the go-to for sports cars and muscle cars, as it’s all about power and balance.
RWD downsides:
- Traction in lousy weather: In wet, icy or snowy conditions, RWD cars are more prone to losing traction. Since all the power is going to the rear wheels, they can slip if the road is slippery, and the vehicle will oversteer or fishtail.
- Not ideal for off-reading: RWD is not suitable for off-loading or uneven terrain as it has limited traction on loose surfaces like mud, sand or gravel.
- Less fuel-efficient: RWD is heavier and less fuel-efficient than FWD and, in some cases, more fuel-efficient than AWD.
All-Wheel Drive vs. Rear-Wheel Drive: Performance
When comparing All-Wheel Drive (AWD) and Rear-Wheel Drive (RWD), you must consider how each affects acceleration, handling, traction and stability. Both drive trains offer different driving experiences and are suited for various types of drivers, vehicles and conditions.
Acceleration:
- All-Wheel Drive (AWD): AWD cars are better at acceleration, especially in low traction conditions like wet, snowy or icy roads. Since power is sent to all 4 wheels, the vehicle has better grip and traction and less chance of wheel slippage during acceleration. AWD ensures that even if one or two wheels lose grip, the others can compensate and provide smooth and controlled acceleration in challenging conditions.
- Rear-Wheel Drive (RWD): RWD cars are better on dry roads, especially high-performance ones. With power going to the rear wheels, the car benefits from weight transfer to the rear during acceleration, improving traction. But in wet or slippery conditions, RWD cars struggle with traction and can spin or fishtail.
Handling:
- All-Wheel Drive (AWD): AWD cars are more stable in corners, especially in bad weather or slippery conditions. The system distributes power between the front and rear wheels, providing better grip and control when cornering. AWD reduces both under steer (when the front wheels lose grip) and oversteer (when the rear wheels lose grip) by adjusting power distribution.
- Rear-Wheel Drive (RWD): RWD is more fun and engaging. Separating tasks between the front wheels (steering) and the rear wheels (power) allows for better cornering and more precise control, especially on dry roads. RWD cars are preferred by driving enthusiasts for their responsiveness and the connection between the vehicle and the driver.
Traction and Stability:
- All-Wheel Drive (AWD): AWD is great for consistent traction and stability across the board. Whether you’re on dry pavement, wet roads or snow-covered streets, AWD sends power to the wheels with the most grip. AWD is perfect for those who drive in unpredictable weather or on dirt roads. AWD also helps with cornering stability so the car stays planted during turns.
- Rear-Wheel Drive (RWD): RWD is best on dry roads where traction isn’t an issue. RWD cars struggle to maintain traction on slippery or uneven surfaces, especially if the rear wheels lose grip. This can make RWD cars prone to oversteering, especially during hard acceleration or cornering in harmful conditions. However, RWD is great for stability and balance on dry roads, especially in performance cars.

All-Wheel Drive vs. Rear-Wheel Drive: Which is Best for You?
The choice between AWD vs RWD ultimately comes down to your driving habits, climate and personal preference. Both have benefits, so the right choice depends on what kind of driving you do most.
Choose All-Wheel Drive (AWD) if:
- You live in a region with frequent rain, snow or ice: AWD is better in bad weather, perfect for drivers who drive on wet, slippery or snow-covered roads. AWD prevents wheel spin and maintains control in low traction conditions.
- Want a Car for All Conditions: AWD is perfect for drivers who want a car that can handle paved roads and light off-road trails. Its ability to send power to the wheels with the most grip gives you peace of mind when driving in different environments.
- Need a Family Car or Daily Driver: AWD cars are great for families or commuters who want safety and stability in all conditions. AWD reduces the chances of losing control in bad weather and makes for a smoother and safer drive.
Choose Rear-Wheel Drive (RWD) if:
- You live in a warm or dry climate: If you drive primarily on dry roads and don’t encounter much snow or rain, RWD is better for performance and handling. The balanced weight distribution and precise handling make RWD cars perfect for dry conditions.
- You’re a driving enthusiast: RWD is loved by driving enthusiasts who value handling and performance. Cars with RWD are known for their agility and balance, which are perfect for drivers who like to take corners and accelerate fast on clear roads.
- Sports Car or Muscle Car: Many performance cars like sports cars, muscle cars and luxury sedans are RWD because they give the handling and acceleration that performance drivers want.
AWD in Bad Weather
One of the most significant advantages of AWD is that it can handle bad weather. Whether driving in rain, snow or icy conditions, AWD systems are great at maintaining traction and keeping the car stable even on slippery or uneven roads.
AWD in Rain
In rainy conditions where the roads can get slippery due to water accumulation, AWD helps to maintain grip by sending power to all four wheels. This reduces the chances of hydroplaning, where the tyres lose contact with the road due to water. AWD vehicles automatically adjust the power distribution to maintain traction on wet surfaces so the driver can drive safely even during heavy downpours.
AWD in Snow and Ice
It is priceless in snowy and icy conditions where traction is severely limited. The system continuously monitors the road surface and adjusts the power distribution to send more power to the wheels with the most grip. This prevents wheel slip and improves the car’s ability to navigate icy roads or climb snow-covered hills. For drivers in areas with harsh winters, AWD gives you a sense of security and confidence that RWD cars just can’t.
AWD in Off-Road Conditions
These type of vehicles are also suitable for light off-road conditions like gravel roads, dirt paths or muddy terrain. AWD is not as robust as 4WD systems found in dedicated off-road vehicles but can handle uneven surfaces without getting stuck.
Off-Loading: AWD vs RWD
If you are off-road or encounter unpaved roads often, the drive train you choose will make a big difference. AWD is generally better for off-loading, but RWD can also handle some light off-road conditions with limitations.
AWD for Off-Roading
It is better for off-roading or driving on unpaved terrain because it gives better traction and control on uneven surfaces. The ability to send power to all four wheels helps AWD vehicles better navigate loose surfaces like gravel, mud or dirt. This is especially important when driving on steep inclines or uneven ground where individual wheels can lose traction.
- Traction on Loose Surfaces: AWD systems automatically send power to the wheels with the most grip so the vehicle can maintain stability and not get stuck in mud or soft sand.
- All-Weather: Wet, muddy or snowy off-roading, AWD can adjust for optimal traction and control.
RWD for Off-Roading
It is not as good for off-roading as AWD since it can’t send power to the front wheels. RWD vehicles will lose traction more easily in off-road conditions, especially on loose surfaces like sand or gravel. However, some trucks and SUVs with RWD may have locking differentials or traction control systems that can improve their off-road capability.
- Limited Traction: RWD can handle bare unpaved roads but struggles in extreme off-road situations, especially in mud, deep sand or rocky terrain. Without power to the front wheels, RWD vehicles have more difficulty maintaining traction when things get rough.
Driving Experience and Comfort
Your choice of drive-train—All-Wheel Drive (AWD) or Rear-Wheel Drive (RWD)—can affect your overall driving experience and comfort. Each ride has a different type, and the right one depends on your preference for performance, handling, and the kind of driving conditions you’ll be in.
AWD Driving Experience
The AWD driving experience concerns stability, predictability, and control, especially in adverse driving conditions like rain, snow, or gravel roads. Since AWD continuously sends power to all four wheels, the vehicle maintains traction and stability, reducing the likelihood of slipping or losing control. AWD is a more conservative choice for drivers who value safety and peace of mind over the thrill of high-performance driving.
- Comfort in All Conditions: AWD vehicles have a more stable ride in wet, snowy or icy conditions, perfect for drivers who encounter harsh weather frequently. Even in dry conditions, the AWD system adds to a smooth and composed driving experience with little to no wheel spin or loss of control.
- Predictability: The way AWD handles the road gives drivers a sense of predictability as power is adjusted continuously to provide maximum traction. This predictability is comforting for drivers who value safety, especially when driving in unknown or unpredictable terrain.
- Less Engaging Performance: While AWD is for stability, it sacrifices some of the dynamic feel you get from an RWD vehicle. The handling is more neutral, and drivers feel disconnected from the road. This is a trade-off for the extra control AWD provides.
RWD Driving Experience
The RWD driving experience is described as more dynamic, engaging, and responsive, hence making it a favourite among driving enthusiasts and those who want a more spirited drive. RWD vehicles send power only to the rear wheels, which enhances handling and balance, especially on dry roads.
- Engagement and Control: RWD vehicles are known for their sharp handling and more interactive drive. Since the front wheels do the steering and the rear wheels deliver the power, the driver has more control, especially in performance cars. This layout also allows for faster acceleration as weight shifts to the rear wheels when the vehicle accelerates.
- Sporty and Fun: Many sports cars and performance vehicles use RWD to give you precise cornering and quick acceleration. RWD is more exciting than AWD if you like to push your car to the limit – whether on a twisty road or a track.
- Not Ideal in Bad Weather: But RWD has a downside. In the rain, snow or ice, RWD cars are more prone to oversteer (when the rear wheels lose grip), making them harder to control in slippery conditions. If you live in an area with bad weather all the time, this can be a big minus.

- Performance Cars with AWD Variants: Performance vehicles like the Porsche 911 and Nissan GT-R have AWD versions to give better acceleration and handling while keeping the connection to the road even in slippery conditions.
Vehicles with Rear-Wheel Drive
RWD is found in vehicles that prioritise performance, handling and sportiness. RWD vehicles are popular in:
- Sports Cars and Performance Vehicles: Many sports and high-performance vehicles have RWD because it’s more fun to drive, with better balance and handling. Cars like the Ford Mustang, Chevrolet Corvette and BMW 3 Series have RWD to give you powerful acceleration and precise handling.
- Luxury Sedans and Coupes: RWD is common in many luxury sedans, especially from brands like Mercedes-Benz, BMW and Jaguar. These vehicles give refined driving dynamics with smooth handling and strong acceleration.
- Pickup Trucks and Heavy-Duty Vehicles: Trucks like Ford F-150 or Chevrolet Silver ado come in RWD configuration, especially in models for towing and hauling on paved roads. While trucks often have 4WD as an option for off-road use, RWD is the default for on-road use.
- Muscle Cars: Classic American muscle cars like the Dodge Charger and Chevrolet Carom go RWD for the raw power and rear-wheel traction that makes acceleration and performance.
Maintenance and Repair Costs
When choosing between AWD vs RWD, you must consider the long-term costs of maintenance and repairs. Both systems have different parts that need attention over the vehicle’s life.
AWD Maintenance Costs
AWD systems are more complex than RWD systems since they have additional parts like differentials, transfer cases and driveshafts that send power to all four wheels. That added complexity means higher maintenance and repair costs down the line.
- Moving Parts: AWD vehicles have more parts needing maintenance, like additional differentials and clutches. Those parts wear out over time and need to be serviced or replaced to keep the AWD system working.
- Tire Maintenance: AWD vehicles need more frequent tire rotations to ensure even wear on all four tires. Uneven tyre wear can cause AWD issues and expensive repairs if improperly maintained.
- Higher Repair Costs: If a part of the AWD system, like the transfer case or centre differential, fails, the repair cost can be much higher than for a similar issue in an RWD system because of the system’s complexity.
RWD Maintenance Costs
RWD systems are simpler than AWD systems, with fewer parts to maintain and repair. That simplicity means lower maintenance costs over time.
- Fewer Parts to Maintain: RWD vehicles have fewer moving parts, making them more accessible and cheaper to maintain. No AWD system means no costly repairs related to power distribution.
- Lower Repair Costs: RWD systems are generally cheaper to repair than AWD systems because of their design. For example, repairing a rear differential in an RWD vehicle is usually more affordable than fixing the complex AWD system in an AWD vehicle.
- Tyre Wear: RWD vehicles don’t need as frequent tyre rotations as AWD vehicles, but the rear tyres may wear out faster since power is sent to the rear wheels. But that’s usually less of a concern than the maintenance needs of an AWD system.
Which one is for you?
The choice between AWD vs RWD is mainly based on your driving habits, the climate where you live and what you prioritize: performance, comfort and safety. Each has advantages, but the right one for you will depend on your needs.

FAQs
What’s the difference between All-Wheel Drive (AWD) and Rear-Wheel Drive (RWD)?
AWD sends power to all four wheels of the car simultaneously or selectively based on road conditions, giving you better traction and stability in adverse weather like snow, rain or off-road conditions. It adjusts power between the front and rear axles to prevent wheel slippage, so it’s suitable for all-weather driving.
RWD sends power only to the rear wheels while the front wheels do the steering. This setup gives you more precise handling on dry roads and is preferred by enthusiasts for its performance-oriented characteristics. But RWD struggles with traction in bad weather like ice or snow as it doesn’t have the front wheel power to stabilise you.
Is AWD better than RWD for winter driving?
Yes, AWD is. AWD has better traction and control in slippery conditions like snow or ice; it sends power to the wheels with the most grip. This reduces the chance of losing control, skidding or slipping in icy weather or snow.
On the other hand, RWD vehicles struggle in winter because all the power goes to the rear wheels, which are more likely to lose traction in slippery conditions. AWD is the safer choice if you frequently live in an area with frequent snow or ice.
Is AWD more expensive to maintain than RWD?
AWD is more expensive to maintain than RWD because of its complexity. It has additional components like differentials, transfer cases and extra driveshafts, which need maintenance and are more prone to wear and tear. AWD also requires frequent tyre rotations to prevent uneven wear and keep the drive train healthy.
RWD is more straightforward and has fewer moving parts, so it’s generally cheaper to maintain and repair. The simplicity means fewer components to break or need regular servicing.
Which drive train is better for performance cars, AWD or RWD?
For performance cars, RWD is preferred because it’s more engaging, balanced and dynamic. With power to the rear wheels and steering to the front wheels, RWD gives sharper handling, better cornering and better acceleration on dry roads. That’s why many sports and muscle cars are RWD; they allow drivers to push the limits of performance.
However, AWD is used in some high-performance cars to provide better traction and control, significantly when accelerating hard or in less-than-ideal conditions. AWD helps manage high power by distributing torque to all four wheels, more grip and stability.
Does AWD improve fuel efficiency than RWD?
No, AWD generally decreases fuel efficiency than RWD. AWD is heavier and has more moving parts, so it needs more energy to operate. The added weight and complexity increase fuel consumption because the vehicle is sending power to all four wheels or getting ready to do so even when AWD is not needed.
RWD is lighter and more straightforward, so it consumes less fuel and is more fuel efficient under normal driving conditions, especially on dry roads where extra traction is not needed.
Can I go off-roading with an AWD or RWD vehicle?
AWD is better for light off-roading than RWD because it has better traction on uneven or slippery surfaces like gravel, mud or dirt. AWD sends power to the wheels with the most grip so you can drive on rugged terrain without getting stuck.
RWD vehicles aren’t designed for off-roading. Since power only goes to the rear wheels, RWD vehicles can’t maintain traction on uneven or loose surfaces and will slip or get stuck in mud or sand. Some RWD trucks or SUVs may have off-road packages, but AWD is generally the best way for off-roading.
What types of vehicles have AWD or RWD?
- AWD vehicles are found in crossovers, SUVs, luxury sedans and some electric vehicles (EVs). Subaru, Audi, BMW and Volvo offer many AWD vehicles. AWD is also standard in performance cars that need extra traction for high speeds or lousy weather.
- RWD vehicles are found in sports cars, performance sedans, luxury cars and pickup trucks. BMW, Mercedes-Benz, Chevrolet and Ford offer many RWD options, especially in high-performance vehicles like the Mustang, Carom, Corvette and full-size pickup trucks.
Which is safer, AWD or RWD?
AWD is generally safer overall regarding traction and stability, especially in bad weather like snow, rain or ice. The ability to send power to all four wheels makes the vehicle more grippe and reduces the risk of skidding or losing control.
RWD can be as safe in dry conditions but becomes less reliable when wet or icy roads compromise traction. RWD vehicles are more prone to over steering, making them harder to control in low-traction environments. However, with proper driving techniques and winter tyres, RWD vehicles can still be safe in winter conditions, but AWD will always inspire confidence in those environments.
Is AWD always better for daily driving?
Only sometimes. While AWD provides extra safety and traction in various conditions, it’s not always necessary for daily driving, especially if you live in a region with mild weather and primarily drive on dry roads. RWD vehicles are more than capable of daily commuting in average weather and generally have better fuel efficiency and lower maintenance costs.
But if you encounter rain, snow or off-road conditions frequently, AWD might be the better choice for your daily driving needs due to its versatility and extra traction.
AWD or RWD?
There is no one correct answer to AWD or RWD – it depends on your situation, where you live and what you want.
- Choose AWD if you live in a wet, snowy or icy area or want a car that can handle different terrains and extra stability. AWD is also great for safety and all-weather performance.
- Choose RWD if you live in a dry climate and want performance and handling. RWD is for performance enthusiasts who want a more connected and responsive drive. If you want a more fuel-efficient car with lower maintenance costs, RWD is probably the way to go.
