I have 2014 76 V8 Turbo Diesel. Fuel consumption is consistent at around 12.6 l/100km, or 7.9km/L at 120. Slightly oversize tyres so speedo reads exactly what the GPS speed reflects. Vehicle has been chipped though and is fitted with a 76mm De Graaf pipe.
@Roadhawg , read above - I get a little better figure with my 79 DC V8 but I've done a bit more on top of what Jughead mentions (better RH-bank feedpipe to turbo, improved turbo intake side and Armax snorkel, higher 5th-gear ratio in gearbox with on top of all Boosttech mapping with an EGR-delete). If driven normal (that's moderately for you because of all the torque&power on tap!) then the consumption is really not bad.
A stockstandard V8 will return in the 6 kilometers per liter irrespective of what you do with it, or worse if you venture in dunes.
Compared to the 4.5 V8, the 4.2 is slow, very slow.
Yay & Nay - Yay when compoared to the V8, Nay when on the highway, where it cruises with the rest of them!
Consumption-wise it again is horrendous in stock form, but without intake-restrictor and some other minor things (freeflow exhaust & electric fan) it becomes more eager (yeah, some will call this a misnomer - but again, do not compare to the V8) as well as frugal, I get figures now around 9km/L with my Troopy.... in town and on the accompanying highways, it's my daily drive now.
Sure, if you scream it in every gear (a nonsensical thing to do with the 1HZ engine...) then yeah, you'll be seconds quicker (WOW hmm?) but the consumption goes way up! Some do this yes, but this engine loves its lazy-torque nature to be used, it actually pulls from below 1000rpm!
The V8 does this too but not as much as the 1HZ does, but it willingly purrs through town at really lazy rpm's... which will pick up hastily if you put your foot down, without any baulking smoke or other wrong signs if the engine is tuned properly - and here a warning, no wait, a WARNING: there's lots of paluka's out there who will sell you a map which will let the motor storm wildly, at cost of heaps of fuel and loadsa smoke which will foul your intake & turbo no end, with the result of shortlived-only happiness....
Don't ask how I know this, but now all is fine and will be for a looooong time to come, it's a Cruiser after all!
