The system operates in the 2WD mode but will automatically divert power to the other wheels if slippage is detected, thus temporarily engaging the 4WD until traction is regained. Next up is the full-time 4WD system. Full-time 4WD employs front, rear and center differentials that allow individual wheel speed to vary.
Correspondingly, what Does 4wd AUTO mean?
Automatic 4WD is a full-time system that lets the vehicle operate in 2WD (either front or rear) until the system judges that 4WD or AWD is needed. It then automatically routes power to all four wheels, varying the ratio between front and rear axles as necessary.
What is a four wheel drive vehicle?
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously.
Older 4WD systems must be manually shifted between 2WD and 4WD and from 4HI to 4LO while the vehicle is stopped. Newer systems have electronic push button 'on the fly' features that let you shift while driving. An AWD car can deliver all engine torque to all four wheels all the time.
We've listed the eight least expensive all-wheel drive cars, giving options to buyers entering a long winter.
- Suzuki SX4. While Suzuki did leave the US market, its SX4 compact is still at dealers.
- Subaru Impreza.
- Subaru Legacy.
- Subaru Forester.
- Nissan Juke.
- Toyota Matrix.
- Subaru XV Crosstrek.
- Kia Sportage.
The term 4×2 is also used, to denote four total wheels with two being driven. Most road vehicles use a 2WD layout due to its light weight and simplicity. Traction on the road is usually sufficient that the driving force can be reliably transmitted through only two wheels.
The upside: FWD cars can actually be pretty tenacious in the snow because the weight of the engine/transaxle is sitting right on top of the drive wheels. FWD is vastly better in the snow than a rear-wheel-drive car. FWD is also more economical — both to buy “up front” and to operate over the life of the vehicle.
Most part-time 4WD vehicles have locking hubs on the front wheels. They spin freely, and the rear wheels of the car do all the work of moving the vehicle. When 4WD is engaged, the locking hubs lock in the front wheels to the front axle allowing them to get torque from the engine.
The other advantage RWD cars offer is better balance — and because of this, better handling. While a FWD car has most of the weight of the engine and transaxle (the transmission and axle assembly are one unit in a FWD car) over the front wheels, a RWD car spreads the weight of its drivetrain more evenly front-to-rear.
If you live in a place that gets frequent snow storms, an all-wheel-drive vehicle with winter tires will be very capable. And some AWD systems function better than others in terms of helping drivers get traction. But most AWD drivers don't think of adding winter tires.
If you've ever spent time driving in the snow, then you've probably realized that front- or all-wheel drive is a much better choice for traction than rear-wheel drive (RWD). And if you haven't driven in the snow, you're probably curious why so many people recommend against RWD vehicles.
Although not all RAV4s are four-wheel-drive, RAV4 stands for "Recreational Activity Vehicle: 4-wheel drive", because the aforementioned equipment is an option in select countries. In most markets, the RAV4 is the only compact SUV or crossover available from Toyota.
4WD (whether AWD or not) is FWD+RWD. "AWD" is the term used for vehicles with 4WD built and intended for full-time on-road use, equipped with a center differential between the front and rear axles. 2WD refers to either FWD or RWD, besides also referring to a 4WD vehicle shifted out of 4WD.
This video explains the workings of four wheel drive (4WD), and gives a definition in order to differentiate different types of four wheel drive and all wheel drive. Four wheel drive simply means 4 wheels are driven, and many times this is accomplished through the use of a transfer case.
The low-range four-wheel-drive setting is for the serious stuff – deep sand, snow, mud, crossing water, climbing rocks and ascending/descending hills. When you use four-low, keep your speeds low, too (under 40 mph or so), as you're not actually gripping the road any better but you're applying more torque to that grip.
In general, cars equipped with 2-wheel drive get better gas mileage than models that use all-wheel drive or 4-wheel drive. There's a reason: AWD or 4WD cars have to send power to each of the vehicle's wheels, which requires extra energy. AWD cars also offer worse gas mileage than 2WD rivals because they're heavier.
Most 4WD vehicles tend to operate in RWD mode until four-wheel traction is required. All-wheel drive is often confused with four-wheel drive but despite the fact both engage all four wheels, their are some key differences between the two. Generally, a AWD system operates as a RWD or FWD vehicle– most are FWD.

A 4x2 or 2WD is a vehicle that has a two-wheel drive (2WD) with four wheels. "4x2" in a 2WD vehicle means there are 4 wheels total and 2 wheels that are driven. The driven wheels can be either back or front wheels but are usually the back wheels.
4 x 4 (4WD) - Is a vehicle that has four-wheel drive (4WD). "4x4" in a 4WD vehicle means there are 4 wheels total and 4 wheels that are driven. "4x2" in a 2WD vehicle means there are 4 wheels total and 2 wheels that are driven. The driven wheels can be either back or front wheels but are usually the back wheels.
So while 4WD and 4x4 are the same, AWD is different. 4WD and 4x4 are basically the same thing - one stands for Four Wheel Drive, the other is Four By Four. All-wheel drive vehicles will usually have three differentials - front, rear and centre to distribute torque between the axles.
