Don't go by the "avg" that the onboard computer gives you....calculate it the old fashioned way between fillups. And yes, modern engines still need breaking in to get their best power/mpg.

How can you worry about mileage when you haven't actually driven the car? It will take like 50-100 miles just for the ECU to build up the VE tables...

And this.

My understanding is that some new engines are extremely tight (mine was) and they do need to be broken in to get proper mileage.

Warm it up and then bury your foot in it for a good break in.

Yeah, new cars definitely need to be broken in. The difference these days is that it takes significantly less time than it used to. Once warm, make sure you rev it a bit and don't keep it at constant rpms or idle for a while in order to force the rings to expand against the cylinder walls and properly burnish them. Back in the day these clearances and the honing processes were shit so it took a lot longer to do this. I'm also in favour of driving a new engine with gusto (once warm) as I feel it helps high-rpm fitment in the long term. Also, change the oil within 200km as there will inevitably be little metal bits in there from any break-in process and you don't want them shits circulating.


No matter how new, 34 km means the car is not quite broken in yet.


OP, I think the reason that car is getting such shit mileage is two-fold. One, it was probably not broken in properly which is mostly due to, Two, it's a test drive vehicle. Ignoring the fact that almost any test drive car will be bagged on, think frequent starts for short trips which is really not great for a diesel engine. Even little diesel engines take more time to warm up and you know that car hasn't had that. With that in mind, the kms are really low so it's not really an accurate figure.

did the both of you go from mildly lucent to totally in the space of two posts??

OP, don't listen to these fools, they just proved that they don't have the mental acumen of theWITLESS on B12 supplements.

ALL new motors and trans are dyno tested before installation into a car, the equivalent of 200 or more miles for most manufacturers (unless you're talking Russian T34 tanks, where you have to fish out about 10 lbs of metal shavings after the first 15 minutes). 34km--21mi--is just enough to drive it out of the assembly plant, to a parking lot, to a transporter, off the transporter, to the dealer parking lot, and maybe a bit more moving around on the lot. Given that, 14l/100km is about 20mpg, which isn't surprising at all given the type of driving (not enough time for full warmup, super short trips, etc).

So, yeah, stfu and stop worrying, you'll get your 50mpg soon enough.

Those little doo-dads are never worth a shit. Do it the old fashioned way by filling up twice and dividing the distance by the fuel.

Are you comparing diesel vs gas versions?

Truth is, a lot of older cars made respectable gas mileage.

And tighter tolerances should mean a longer break-in period. :-P Just kidding.

the gas version is utter crap, had one as a rental and it felt slower and less responsive than the diesel. I'd never buy one of those. there are a few of these diesel cars in the motor pool. The others get about 6l to 8l/100km and they're all pretty new cars.

If 34km is all it has on it, the car probably see a lot of idle, hard acceleration, hard deceleration, no constant speed, and driven 3km at one time for test drive. It wouldn't be a surprise.
normal city driving - about 35 to 50 miles an hour.

Is the fuel economy meter an "instant L/100km" meter or "average"?

If it's instantaneous, that mileage at idle is quite good ... my car shows 99.9L/100km when sitting at idle.

If it's average, it's still probably normal for a brand new car that's only seen delivery/test drive miles (the majority of which are hard driven).

Most manufacturers these days have good diesel engines, Hyundai included.

I'm guessing it's a 1.6 CRDi. It should get way WAY better mileage than that.

maybe it's just been reset for the running average? I reset mine after a fill up and my prius sometimes reads 14.4+ L/ 100 km if I really get on it.. but it stabilizes as I drive more.

TSRH, dealers around here like to leave the AC on and the car idling a lot of the time when they're showing people cars.

it seems to last forever on one tank of diesel.



But I'm not driving it much though.
