How do we call cars which 4WD is not always on, however you switch it on using separate gear shift transmission like the picture below.

Thanks in advance.

    Today we'd call it "part-time" four wheel drive. "Back in the day", pickup trucks had what we called simply four-wheel-drive (4WD). It required manual locking of hubs (assuming they ever UNlocked - some really old 4WDs had always-connected hubs) and manual shifting of a transfer case into 4WD. Today's pickup trucks might have electrically operated shifting, but it's fundamentally part-time 4WD. – mike65535 Apr 19 '19 at 12:56

The type you are showing above is just Four Wheel Drive (4WD). It can be switched between ranges of the transfer case:

  • Two Wheel Drive (2WD or 2H on the gear shift above)
  • Four Wheel High - This is all four wheels getting power with the transfer case in the high range for greater speed. This is the same gear ratio as used for 2H.
  • Four Wheel Low - This is all four wheels getting power with the transfer case in the low ranger for greater torque and slower wheel speed.

With the type you have shown, this is a manual transfer case, shifted by a gear lever. Some older vehicles used to have two shifters sort of in a scissor pattern to do this, whereas now you'll only see one gear shift lever. There is also an automatic transfer case, which has a push button with servos in the transfer case to shift through to the different modes/ranges.

There is also, full-time 4WD, where you can switch between high and low range in the transfer case, but you cannot switch out into a 2WD configuration.

Then there is All Wheel Drive (AWD). This is technically 4WD, but there is only one transfer range, which is always for highway speeds. It is always engaged.

  • @Error1004 what "below specs"? – Solar Mike Apr 19 '19 at 5:50
  • @SolarMike & Pᴀᴜʟsᴛᴇʀ2♦ thanks a lot. Clear and understandable. Could you please proposed cars the below specs: 4WD (NOT all time, driver should initiate them), automatic transmission & 1.5L to 2L? – Error 1004 Apr 19 '19 at 6:20
  • There are websites where you can do that search. Asking a shopping question is likely to get your question closed as "off-topic". – Solar Mike Apr 19 '19 at 6:23
  • @Solar Mike could you please introduce such websites? – Error 1004 Apr 19 '19 at 9:09
  • @Error1004 - We are not a site to give recommendations. I will say, however, to get where you want to be, I'd be looking at Subaru. – Pᴀᴜʟsᴛᴇʀ2 Apr 19 '19 at 15:30
