Hey guys,
Just got back from a trip to Balarat and back. Managed to use 14.42L and traveled 368.2kms Apart from the usual tricks to increase fuel economy, i set behind one of the big trucks (B doubles?) both ways. Was sitting close behind so the wind resistance was minimal, if anything i was actually getting sucked along. The thermofans had to come on every 8 minutes or so. At one state i didn't touch the accelerator for over 50kms. It was only on the uphill sections i had to touch it, on the flat and downhill it was just idling/ticking over. So there ya go, to hell with the toyota prius, go get yourself a VR commodore and a large truck

is that a readout from the level 3 dash, or did you actually go and fill your car up after the trip?

Hard to beleive i know, but it did 3.9L/100km. Bloody tiring though, almost 4 hours and the only thing you can stare at is the trucks brake lights. |

I knew it was a bit of a hole, but I never knew Ballarat was that far downhill ^___^

It does work tho, if you get close enough there almost no wind resistance at all. I've drafted B doubles over long distances before. You have to get within a totally illegal distance to do it but trucks never follow you at a legal distance and they stop half as fast so it's all fair square :d

lol you are such a tool, why even buy or own a commodore if you are so negative towards them? in a few of your posts all you ever try to do is put everyone down, if you know so much as you claim then theres no need to even come on this forum

Hey I like VL's
Ignore people who try to troll others around the forums, like bad smells they do tend to get bored and drift away. Personally though if he knows allot as someone stated above thats no reason NOT to come here, it's a good reason to come and share and help.

You also probable found the fornt of the car can "wobble" a bit as the wind rips of the back or the truck. When trucks were made to travel at 80kph you had to pass heaps of trucks and the RX4 I had really shook its head at times as you sat behind them ready to pass.
PS Greenfoams latest tune in the VN wagon has returned 10.6 L/100 over 1,650 kms of city driving. This is by far the best return yet. Highway stuff should drop it into the 8's non wind assisted (or B-double) ![]() The V8 ain't fairing so well - lots to do with my bad driving and cold short runs to work. It's currently getting 16 L/100. but at 100 kph instant reading drops to around the 9's.

It works well, dunno bout the 3.8 litres but wow if it did. I do it regurlarly when i drive out to the misses's work. Follow the truck route all the way there catch a big truck and draft it... slow up hills but lol. This has been proven on myth busters, 40mtrs down to 10 mtrs works best any closer and you will increase your usage and put yourself in danger. But i did have a mate with a hilux who set up with a mate to drive his hilux bumper touching the float and just cruised behind without having to steer.
And from the site: Drafting behind a big rig will improve your car’s fuel efficiency. confirmed To test this myth, the build team procured a car, a big rig, and a device that could measure a car’s fuel efficiency. They then drove the car behind a moving big rig at various distances ranging from 100 to 2 feet and measured the amount of fuel the car consumed. The Build Team discovered that the closer the car was to the big rig, the less drag is produced, thus the more fuel saved. At just ten feet, the car managed to increase its fuel efficiency by 40%. Drafting at two feet was slightly lower than the ten foot distance, mainly because Grant had to keep working the car pedal to maintain distance from the truck. However, that did not dispute the fact that drafting actually can increase your car’s fuel efficiency. However, the Build Team has warned that drafting is incredibly dangerous because the truck driver may not able to see you and you may not be able to react in time if the truck were to make a sudden stop. And source MythBusters Episode 80: "Big Rig Myths" Ehehe i can see alot of commodores now sitting behind trucks...

why not just move it up against the rear bar of the truck/trialer. then when he brakes he slows you down too

Bloody nice work feistl! I might give it a shot next time, although i've had too many bad experiences sitting behind trucks with rocks flicking up and what not and also them swaying onto the edge of the road like their way of saying ''pass me, pass me'' Although sometimes I probably just imagine it when they don't mean too lol. I try not to sit behind the mongrels these days and just pass them soon as safe to do so. But hey, maybe a nice road I'll do it but prob not the country roads...

another problem is if there is some sort of obstacle on the road, the truckie will see it and aviod it, but you wont, until its right in front of you, giving you a very small reaction time. but hey, fuel is expensive, i reckon its worth the risk

Well i have been able to get 7.5L/100km in the past under normal driving, so 40% save would be almost right.
Yeah i was worried about rocks and stuff but this particular truck have a very low/flat back. As to running into it, well yeah but you wouldnt do much damage. Think about it, say he starts braking really hard... He might drop from 80 to 75 before you run into him... So thats the same as you driving into the back of a parked truck at 5kph. Not really going to do much damage. In fact, its probably better to be very close and run into the truck as there would be very little speed difference. Whereas if you have a 10m gap and manage to hit him, there would probably be a much bigger speed difference and bigger impact. Not really practical though, as it takes a LOT of concentration and takes ages to get anywhere. But yeah, interesting results. |
