    a lot of people seem to think that kombis are not fuel efficient. ..
    so to get some perspective i found this on a toyota hiace web forum

    in conclusion a 40 yo vw van gets similar fuel ecconomy to a 10 year old toyota

    not bad ...in my opinion

    Another poor economy vehicle doesnt mean the kombi is let off the hook :)
    A bay can get between 10.5 and 12.5 as a median expectation.
    The 10.5 being unatainable for most.

    Modern lwb vw kombi diesel can get 8km/ litre or better at 100km/ hr.

    Know of one split claiming 7 crising with other kombis and 8 @ normal hwy limits.
    Methodology in calculating sound.
    Suby motor, roof rack, lowered.

    I accept that they get what they get.
    Reasonable if design, normal wear and tear, what was considered normal economy for the period are the governing factors.

    But for sake of discussion, improvements can be gained if one is inclined.
    And there are no physical/ theoretical barriers to gaining a margin of improvement.

    Rating fuel economy usualy has a subjective framework. I have no issue with that.
    But if one looks at the disbursement of energy contained in the fuel then it is quickly clear that the fundamental exchange of energy in fuel / motion ratio is poor.
    And has realistic room for improvement.

    i guess the point i was trying to make was that a Kombi engineered in the mid 70s is matching vehicles of similar dimensions made this century ...

    i suspect it would compare with other similar size vans made by other manufacturers too.

    i never complain about my fuel economy
    i am impressed by it

    I agree Betsy,
    They are ,in fact, still superior.
    If shape & drag coefficient are factors that dictate fuel efficiency I understand that Kombis have one of the lower drag coefficients of vehicles of that era despite looking like a box going thru the air. Yes..the roo bar/spare tyre out the front changes that.
    They 'air flow well' (I've got a later vehicle & you can't drive with the back windows down as it 'pulses' in the air flow & pumps the inside of the car & your ears) & have never been the cheapest to run but they are the most FUN.
    Never had a weather shield on my Kombi. The air is just going the right way.....out! That's cos of the way the air intake is in front!
    Nothing will ever beat trailing link suspension of a Kombi until they do the same on something else!!!!
    Open challenge...fuel consumption aside.....nothing beats Kombi T2 (or rear engine anything with trailing link ) suspension & balance of the car with the space & versatility they have!
    My 12 litres/100km is the most affordable joy I've ever had. A lot cheaper than divorce & a whole lot more fun!
    Cheers,
    David H

    With the body shape, bulbar and roof racks I run, I save on regular brake disc and drum shoe replacement costs.

    When I lift off the "go" pedal, it slows down very nicely, without having to touch the brake, even on downhill runs. ;)

    I have noted every fuel fill and odometer reading since I bought my kombi in 2009.
    It is now a daily driver and is filled every second week, this gives me two weeks of commuting and one longish trip on the weekend.
    From Sawtell to Coffs Harbour, about 12 km's each way and then on the weekend, Valla, Dorrigo, Yamba etc.
    Commuting about 15 L per 100 Km
    Highway about 12.5 L per 100 Km (depending on speed) Generally around 100 to 105 KMH

    Our ML 55 Mercedes uses more fuel, about 18-20 L per 100 in town and maybe 14 L per 100 Km on the highway!

    Happy with the Kombi!

    ........ and thats at 120kph+ (not that I do that very often). Still reckon there's nothing like a well built, balanced, light weight, and well fed air cooled motor. At 110-112 it passes through the sound barrier so wind the stereo right down, wind the windows right up as the wing mirrors fold in at 115 just like an F111 and let it settle to a high speed cruise with less throttle that that used around town at 60kph (5-10mm max). Just love this 5 speed air cooled bus - it's cheaper to run than my kids MY01 2.5 Subaru .........and shed loads more fun. One day I'll find out how little fuel it can use if driven at Nanna speeds.

    or a modern engine.
    T5 will get between 7- 8 l/ 100km at normal hwy speeds. (Thats 110km/ hr )
    High top lwb, 8.6

    really? that is medium size new car impressive.

    my old beast was using close to 18L/100 before retiring......In hind sight most of it probably came out the to of the tank and around the injectors.

    I agree. Amazing figures that in my mind defy the size of vehicle
    Both common rail injected diesel. Think turbo ?
    Quoted by friends who owned respective vehicles and mechanical enough to do accurate calculations so assume numbers representative.
    First set was medium wheelbase on trip to victoria.
    Return towing empty horse float bit slower at 11 l/ 100km.
    Lwb high top courier run mainly highway but not spared.

    Figures like that are just giving VW a bad name............. making them look to be economical! :eek:

    Next they'll claim diesel emissions are next to non existent....o_O

    Daughters car (Suzuki Alto...1 litre Indian build 3 cylinder tall geared) only does 800 km on 35 litres!
    Another one giving a bad name!:rolleyes:
    Coming from the V8 era of gallons/mile I continue to be stunned.:rolleyes:

    Depends on what its compared to.
    Against a kombi anything modern would look pretty good ;)

    As added on weight decreases ones fuel economy its really hard to know what is normal. Since having both carbies rebuilt it appears to have gone from { and I use MPG } 22mpg t0 24 MPG, working on a long trip where they has been multiple fill ups and carrying as little as possible {only what is necessary.
