RoverChic said:Matt ~ Yes they are AWD (all the time 4 wheel drive) which means mega gas guzzlers ..Looking at maybe anywhere between 11-15 mpg.
Ahemm.. little 101:
AWD - all wheel drive
4WD - four wheel drive.
AWD is not full time 4WD
full time 4WD basically means you got both axles (rear & front) engaged all the time. But in open situation and throwing away ETC/HDC and other C - it will still behave like 2WD in loosy traction condition. However full time 4WD is a bit easier on finding traction back. But if you in situation when you got no traction on 1 wheel - that wheel will get all the power, just like with 2WD. And your only hope is to have momentum that throws you away from dangerous place. To help this - Central Lock is designed.
AWD is when actually all wheels getting equally powered when need arising.
However Disco is heavy enough to rarely get into situation on road when you really got to use CDL.
In fact it can do same trails not engaging CDL where others cant move further without going into locked 4L (how i know - i tried it
Mileage however sucks for full time 4WD over AWD. Mostly b/c AWD vehicles are like 1/4 of weight , lower, get better aerodynamics. But AWD vehicles got puny clearance b/c of that.
But 11-15mpg is too low. You can get about 20-21mpg on highways out of Discovery, if you easy on gas, using momentum properly and taking care of truck. City's mileage is the worst. Discovery simply sucks as daily driver, b/c its very heavy and stop-and-go traffic is taking its nasty toll on them. Thats where you may range 9-15mpg, depending on situation.
They arent without quirks, but that what isnt. Good thing about older D1s is that they are much much more simple to maintain. Bad thing - they all now at pretty high mileage. Later D1s are in better shape, but they are more complex.
D2s are a tad bigger, got more electronics in them and may have or not have CDL (lately reintroduced again). Depending on valuability of CDL for your type of offroading it may play some role. They are in better shape normally than D1s. But they are harder to maintain. Bigger engine though - more power. If you care
