What's the difference between all-wheel drive and 4-wheel drive?

4WD is not on all the time, under normal conditions, only the rear wheels drive the vehicle forward, while the front wheels spin freely. To activate a modern four-wheel drive system, the driver has to push a button or pull a lever to engage it. But four-wheel drive isn't meant to be on all the time so you have to know when to turn it on and when to turn it off.

AWD is on all the time, and mostly used in cars, and the computer manages the system. Just going down the highway, the system will send most of the power to the rear wheels, for maximum fuel efficiency, if the road condition changes, such as rain or snow, the system adapts and evenly distributes the power evenly to all 4 wheels, so you have maximum drive grip, with little to no chance of wheel spin.

2WD Cars are less complex than those with AWD or 4WD, and their simpler drivetrains mean improved fuel economy in the long run.

In general, cars equipped with 2-wheel drive get better gas mileage than models that use all-wheel drive or 4-wheel drive.

Thanks for watching

      I love my AWD Subaru Outback, I just hate the poor fuel performance in suburb driving. it has been fully serviced recently, carbon clean, oil, filters, plugs etc. just cannot seem to get better than 350-375 klms per 60 Ltr tank.

      Thats just an old Subaru thing. I worked as a Student for a couple of car dealerships, ine specialised in imports so got to drive many different cars. Without a doubt, the Subarus used far more fuel then any other car of similar displacement. However, I used to own a 78 Cadillac Eldorado with a 425cc (7 litre) big block V8, which was more fuel efficient then my brothers Mitzi twin turbo VR4, which has almost half the power (once I removed all the restrictions off the V8). You really should update your car, new cars have so much better fuel economy with alot more power

      The recognized standard for measuring milage = kilometers per litre/ miles per gallon. Nowhere is your unreliable,"approximate" system found. Find another acceptable, logical system to use. Please.

      Subaru cars, like other AWD cars, can drive only on AWD. Real 4x4 cars can switch between 2WD, 4WD auto, 4WD HIGH range, 4 wheel LOW range or 4 wheel lock. A 4x4 vehicle with a
      locking transmission is far more versatile than AWD vehicles. Subaru is plugging a far inferior vehicle compared to one with a real 4x4 transmission with locking gears and alow range.

      AWD is what most people will use/want. A lot of people dont understand 4x4. I prefer my AWD personally because i dont have to worry about changing anything ever and my car adapts correctly. Like he said as well. People will mess up a 4x4 system if they dont know how to use it.

Think your car to be impossible to move on the meddle of a desert or a forest ...dunno . From other hand ,cars with axis 4x4 and manual transmission are old . Back to 2000 like panjero or Vitara . :(

      You can Absolutely leave your 4x4 in 4 high for long periods of time without ANY damage whatsoever. Clearly you bias to Subaru and their AWD systems...lol ok on demand AWD at best because a subarus transmission and drive componets are poorly made and cannot withstand constant pressure. If the AWD system is put under long durations of active service they will ALWAYS FAIL period whereas a 4x4 system will not. A true locking 4x4 system will continue pushing forward as long as the driver has the peddle down as opposed to weak AWD system's that will either give out or up when forced to actually work. 4x4 system's are always best choice in exstreem weather and or road conditions period. By the way if your slipping in the rain then get better tires and learn how to drive correctly.

      to understand awd in all its parts, do we have to get algorithm of the vehicle :) how can i know in which case the computer decide which power distribution? i want to know which parameters computer collects.
      and for 4wd, i guess it is easy. if i see any risk, i go to 4H. if no risk i go to 2H (for fuel economy). is this correct as basically?

      I’m driving Jeeps since 1978 and I’m currently driving my 8th one - a 2018 JLU 4 door Wrangler Rubicon. I’ve NEVER spun my wheels on a wet surface or going around turns in 2 wheel drive and if you do your driving too fast in those conditions. This video might explain the differences between 4 wheel drive and all wheel drive but that’s it. The rest of the information is BS .

      but have you even driven a car? Dragsters, f1 cars, touring cars and any other race cars uses special tyres designed for their needs along side other mechanics and techniques. Also they preheat the tyres before racing to have more grip. The tyres on your daily car wont give you the same ammount of grip. And even with that FWD cars are easier to control than RWD with less chances to make your car spin.

      You probably shouldn't compare all out race cars with conventional driving vehicles. For traditional front engine cars, in most environments, yes a FWD car gets better traction. Ever driven a RWD car in the snow? They're brutal.
