    Default 1.2L 3 Cylinder turbo fuel consumption?

    Official stated consumption for this 1.2L 3 Cylinder turbo motor in a 2008 is 4.8L/100km.
    Anybody got any real world consumption figures from the trip computer?
    My 1.6L 4 cylinder gets 8.4L/100km in city driving. I just test drove the new motor in a 2017 car
    and while the six speed auto mated to the motor is smooth and tractable the trip computer at
    the dealer said 8.1L/100km ( car had done 10,000km )
    Over what period does a trip computer compute usage? Anyone know?

    Well, you still have to work them hard, turbo or not so real world consumption is much higher. I know my dad's Ecoboost fiesta is quite thirsty.

    Trip computer uses data from last time it was reset, fuel/distance
    So 8/100km will be your consumption if driven the same way.
    A real world figure

    Thats what worry's me. I was hoping for at least something in the high 6's or low 7's.
    Build a hybrid Mr Peugeot.
    Maybe some 2008 owners can check their trips?

    They do build hybrids
    And in Newcastle I see early to mid 6s

    It calculates continuously and stops at 9999km, unless reset.

    That's the sort of figure I would expect from a 10k "demo" car that's been abused by all manner of people.

    For reference my 1.6 GTi gets 6.4l/100km long term - but it's not a sluggomatic, so perhaps not much help.

    If I reset the computer by means of holding the stalk down, it takes about 500-1000 meters before it starts showing a number, and it averages out over time/distance.

    Car Depreciation will be greater than any difference in fuel consumption

    Iím a consumption nut.
    I averaged sub 5/100 over almost 40k in our 308 1.2. 6A.
    Drive it like a quiet diesel using its low rev torque @ <2000 revs and minimise use of friction brakes and you can achieve amazing figures.
    But
    Forget about competing.

    That is genuinely impressive!

    I wouldn't say I'm a 'slow' driver by any means, but driving carefully I'm usually able to match the claimed consumption in my vehicles too.

    Small turbos are brilliant AFAIC.
    Our C4P is doing less than the official combined 5.6 (on E10/95) but I am retired and living in the country so itís not all that difficult.

    Hey Guys,
    If I am not getting 30l/100km I am not trying hard enough or having enough fun
    Bright to Mt Beauty across the saddle wow great drive
    They have wrecked the Forrest to Apollo Bay drive now 80Km/hr.
    Too many tourists driving on wrong side of road
    Any other great drives you have where you can chew the juice in Vic?

    If using E10 ensure you put in fuel system cleaner at every second fill.
    E10 is dirty and fouling and only good for old engines you care nothing about.
    Stick with 98 avoid all those issues

    Thanks for the replies The car will be driven 250km a day in city conditions and gently using 98. I think it seems like I might do better than 8l/100km from the feedback. The 1.2T is a a nice motor/auto box combo to drive. The the 1.5l 4 speed auto is not a bad unit for Ubering either!

    Normally drive just on max torque RPM with low throttle setting, avoid accelerating or pushing it up hills (big fuel burn). There are some tips on the Net for economy driving , drive smoothly - maybe you don't need to drive as if you only had a cup of fuel in the tank but you have to be conscious that the throttle pedal pours fuel into the engine at your command. So it is the driver who has most control on fuel usage. As a Peugeot bicycle rider I've learned to conserve energy on the road! Max Torque RPM is where the engine is most efficient so let the engine do it's driving without forcing it.

    My 1.4L turbo auto Jetta does 5.6L/100 on a trip easily.

    Our Skoda DSG with 1.4 l Supercharged and Turbo engine (CTHE) does 5.5-6.0 around the City, with my wife driving.

    And considerably more when I drive.

    On the highway the best we've seen is around 5.

    Not necessary.
    E10/95 is book approved by Citroen for the C4P and by Holden for the Astra.

    The most economical form of braking is getting off the accelerator earlier.
    And
    Doubling speed gives 4 times the aero drag.

    Same engine/gearbox as the Jetta?

    Care of some confusing maths the fuel consumption increases at the 3rd power:
    https://en.wikipedia.org/wiki/Drag_(physics)#Power
    So twice as fast is 8 times more energy/fuel, but the engine gets more efficient at higher power so its all rather complex.

    Iím old enough to remember the 70s oil crisis and Porscheís research into factors affecting fuel consumption and finding a 2000 rev limit was best for minimal fuel used.

    Our 1.2 cactus gets driven with gusto all the time and since purchase its now up to 32k we get 4.8- 5.1 consistently, if i gun it really hard through tight country roads doesnít seem to make much difference only a lot more fun, this is a fantastic engine
