Vehicle fuel economy comparison

[PsYTraNc3]

Decided to open a thread for comparing fuel economy depending on driving style, fuel type, vehicle and other factors...
Just because

My vehicle: Hyundai i120 1.4 CRDI
eco driving fuel consumption: 5.0L\100km. +- 950km with 48L of diesel
normal driving consumption: 5.6L\100km. +- 870km on 48L of diesel
when driving hard: 6.0L\100km 800+km with 48L of diesel (This is when I decided to really push the car for a week)

My average is about 5.2L\100 and 850-900km on a tank mostly city driving.
What I have noticed recently is that using nitrogen made quite a noticeable difference when driving hard especially.

Would like to see how others compare?

There's no way that putting nitrogen in your tyres is going to affect your fuel consumption. More likely, the equipment used to pump in the nitrogen has a pressure gauge that reads differently to what you were using before and your tyres are harder.

That aside

Vehicle: SLK32 AMG
Eco driving: what the **** is that?
Normal driving: 16l/100km
Hard driving: 20-25l/100km

Average is about 16.5 over the last year.


Vehicle: ML320
Eco driving: 9l/100 freeway
Normal driving: 20l/100 round town
Hard driving: err. right. Unpossible.

Understood I'm no expert....

If hard driving is impossible in an ML then I have no idea what i was doing in my lil i20 :erm: flooring it to do 0-100 in ten years is what i considered to be driving hard.

I concur. Increased tyre pressure leads to better fuel consumption, but lessens grip, especially in wet weather and thus driving style needs to be adjusted.

My vehicle: Atos prime 1.1
eco driving fuel consumption: 5.5L 100km
normal driving consumption: 6L\100km.
when driving hard: Only has a 46kw engine it does not go anywhere fast

lol
Foot flat is normal driving, car is so underpowered

For me, hard driving involves the ESP light giving my passengers epilepsy

You don't turn that **** off when driving hard? What's wrong with you?

Fair enough, but I hate ESP (even though it's probably saved me more times than I'd like to admit). It's like an instant -20 to fun factor.

Here's a thread on the same thing...

Hmmmm, not to derail the thread, but we usually increase our tyre pressures in the rain so that the tyre is able to displace more water, thus allows you to have a bigger contact patch, which leads to more grip. Also, tyre temps are lower in the rain... That might be a factor.

increased pressure = smaller contact patch.

450Nm @ 1200rpm, through an auto box, RWD and short wheelbase...

Agreed, but in the rain it helps to clear water = bigger contact patch with the road, smaller contact patch with the river flowing down the road.

I remember when I was a young kid I went to visit my one friend on their farm. Rained the morning that we had to drive back into town with the car. My friends dad let air out of the tyres and loaded one or two sand bags (not sure actually what was in them) into the boot. I asked why and he said so that the tyres can grip better on the muddy farm road (no tar roads going into the town from the farm)

Lowered pressure = wider contact patch = less chance of sinking into the mud... That's why you drop your tyres to 1 bar when you hit the beach

Sounds deliciously fun, but you get the full 450Nm @ 1,200rpm? What does it do at the wheels, and what do your power/torque curves look like?

It doesn't run nicely on a dyno, the ESP never really switches off so you don't get true figures.

This is sorta what it kinda looks like
