The differences between Dual Motor, AWD and 4WD
All-wheel drive is an increasingly popular technology, appreciated for its advantages in terms of safety and performance. But with the increase in available options, terminology is also becoming more complex, introducing terms such as 4WD, AWD and Dual Motor. In this article, we will shed some light on these acronyms, explaining the differences between all-wheel drive systems and helping you choose the one best suited to your needs.
Dual Motor, AWD and 4WD: what are they and how do they work?
Dual Motor: the most advanced electric all-wheel drive
In electric vehicles, the Dual Motor system represents the latest frontier in terms of all-wheel drive. This is a configuration that employs two independent electric motors, one for each axle of the vehicle. This technology offers numerous advantages over traditional all-wheel drive systems such as AWD and 4WD. Greater control and stability: Dual Motor allows the drive torque to be managed on each individual axle. This results in excellent control and stability, especially on slippery terrain or in demanding driving conditions. For example, if one axle loses grip, the system can send more torque to the other axles to maintain control of the vehicle. Improved performance: The two electric motors provide faster acceleration and more immediate response to driver commands. In addition, the Dual Motor can improve the vehicle's towing capacity. Maximum safety: Independent management of the drive torque at each wheel helps improve safety in various driving situations, such as cornering, braking and skidding. Energy efficiency: Contrary to what one might think, the Dual Motor can also be energy efficient. In fact, electric motors can be used to recover energy during braking, which is then reused to power the vehicle. Dual Motor is mainly found in high-end electric vehicles. Dual Motor is a more advanced technology than both 4WD and AWD, designed to offer high performance and maximise driving safety. The Dual Motor system is particularly suitable for those looking for an electric vehicle that offers the ultimate in performance, safety and control. It is ideal for those who drive on challenging roads, for those who enjoy sporty driving or for those who need a vehicle with a high towing capacity. For those aiming for the ultimate in performance and sporty driving, the Dual Motor may be the most suitable option.
AWD (All-Wheel Drive): permanent all-wheel drive
AWD, unlike 4WD, distributes drive torque to the four wheels automatically and continuously, without the need for manual intervention by the driver. AWD can be found on a wide range of vehicles, both petrol and electric, and offers greater grip and stability on any terrain, even in normal driving conditions. AWD is more efficient than 4WD. AWD is a versatile all-wheel drive system suitable for everyday use. If you often drive on difficult roads or in bad weather conditions, AWD may be a good choice. If, on the other hand, you mainly drive on paved roads and are looking for a more fuel-efficient vehicle, a rear- or front-wheel-drive vehicle may be more suitable.
4WD (Four-Wheel Drive): the traditional four-wheel drive
The 4WD system is the oldest and involves manually sending drive torque to all four wheels. This is done via a specific gearbox and, in some cases, with the aid of free hubs. Unlike AWD (All-Wheel Drive), which distributes torque automatically and continuously, 4WD is only activated by the driver, when necessary, typically in difficult driving conditions. 4WD is generally designed for off-road and difficult driving conditions, on slippery or snowy terrain. If you need a vehicle for off-roading or tackling challenging terrain, 4WD is the most suitable system.
RWD (Rear-Wheel Drive): rear-wheel drive
On a vehicle with rear-wheel drive, power is transmitted exclusively to the rear wheels (or rear axle). This type of drive is still used in many sports cars and commercial vehicles. Alkè electric vehicles precisely have rear-wheel drive, even though they can be compared to 4WD vehicles in terms of performance. Rear-wheel drive allows good weight distribution, which can improve traction and driving stability, provided there is sufficient weight on the rear axle. Rear-wheel drive can then make the most of its advantage through optimal vehicle control, which is less likely to skid.
