Fuel consumption

ScottulusMaximus said:
Lol, unit fail... It's litres per 100km, lower numbers are better. Fecxking retarded way of measuring fuel consumption IMHO but I'll be shot down violently by the next 10 replies stating it's the most accurate blah blah blah. Still don't care how many litres it take to do 100km(I don't drive in 100km blocks), I want to know how many km I can get per litre I put in.

Km per litre is a useless way of measuring fuel consumption.
8km/litre: fuel consumption is one litre.
20km/litre: fuel consumption is one litre.
100km/litre: fuel consumption is one litre.

Not useful.

That is very high for a car like the I20 I would say. I get 6.4L/100KM on my car which I think is a 1.6 engine ..... and is from 2005.

The biggest determinant of fuel consumption is driving style and type of driving.

My SLK which is a tiny car has much worse average consumption than my monstrous ML320.
Because the ML is used almost exclusively for long trips...

Mine is combined urban. Higway from Glenhove onramp m1 to midrand new road and back and then stop and go to get to Parkhurst.

I'm not sure about the new i20, but my previous shape i20 (1.4, exact same engine) averaged around 6.5L/100km mixed driving.

This is what I was thinking wrt the i20 figure.
Because that number is highly suspect.
I've driven a few Hyundais and they seem pretty efficient. Just slightly off from the advertised number.
There was an issue with their 2.0 engines being pretty bad with consumption.

Bear in mind this is Car's long term test figures. They use the cars for various things while they have them. I find it very likely that the dinkytoys are only used for quick runs around town, while the big haulers are used for long trips, holidays etc.

So would that not be an incorrect test procedure?
I guess if they putting out figures to compare with official figures, then they should have an official duty cycle like all other official testers.

If you read the OP, he mentions it's from their long term tests... not their actual calibrated car tests...
 
My Isuzu 2.5L Diesel D-Max 4x4 is averaging 7.2L/100km for the last 34,000km. There's also not a single straight or level road in this damn place.

My Corsa 1.8 GSi in SA used to average 10L/100km in town and 6.5-7L in long distance. :/

Yes but the type of drive will influence the result. So the result here is not exactly objective.
Makes it kinda meaningless then.
Unless of course next to each number they indicate how they drove the car.

The purpose of the long distance test isn't to provide a calibrated fuel consumption figure ;) It's just something they report on as a by-the-way.

That said, the Jetta 2.0 TDI's consumption figure seems spot on for mixed use.

Based on carmag's +/-20000km test


Toyota Auris HSD XR (73kw/142nm) 6.64/100km

Opel Corsa 1.4T sport (110kw/220nm) 6.67/100km

VW Jetta 2.0tdi highline (103kw/320nm) 6.12/100km

Isuzu KB300 DTEQ lx 4x4 DC (130kw/380nm) 9.67/100km

Toyota 86 High (140kw/204nm) 9.58/100km

Audi A7 sportback 3.0 bitdi quattro (235kw/650nm) 8.86/100km

VW gOLF 1.4 tSI comfortline dsg (90kw/200nm) 8.3l/100km

Honda civic tourer (104kw/174nm) 8.99/100km

Hyundai i20 1.4 fluid (74kw/133nm) 9.1/100km

VW Amarok 2.0 bitdi highline (132kn/420nm) 4 motion at 9.78/100

How is a lighter and less powerful engined car like the i20 use more fuel than a bakkie which is way heavier and more powerful ?

That Opel is damn impressive given it pushes out 110kw with only 6.67l used per 100km

/impressed.
 
Whoever drives that I20 has a leadfoot, and is stuck in third gear. In town driving everyday, 60km round trip in N1 traffic gives me 7.2l / 100Km.
How is it that I am so different that this car? and I am driving in the worst bloody traffic you can imagine.
 
Mercedes Benz CLS350 Shooting brake (225kw/370nm) naturally aspirated 3.5l v6 engine in a larger heavier car=9.6l/100km
VW Passat 1.8tsi comfortline dsg (118kw/250nm) 1.8l turbo petrol 4 cylinder in a light sedan=9.95l/100km

OK the benz s consumption is based on conservative route that has been changed to represent realife. The passat figures are based on the 20 000km test but still....
