Hi all

Andrea from Holden's Global Green Challenge team here.

We're up in Darwin making preparations to start on our 3000km drive from Darwin to Adelaide. (where's the hot and humid icon)?!

Our engineers, Simon Cassin and Scott Heywood start the drive today in the 3.0l SIDI Sportwagon.

We'll be keeping everyone up to date (technology permitting) on how we go during the event. Checkout www.facebook.com/holdenaustralia for updates

Pur aim is to improve on our ADR sticker of 9.3l/100km so we're hopeful of achieving some good numbers...

I'll check back to Ls1 when I can so if you've got any questions for our engineers during the course of the week, post them here and we'll try and get them answered for you

I was in there watching the start of the event today. The tesla was getting a lot of attention. Simon was quite chuffed when i asked him if he could autograph the article in top gear australia magazine about him and the car. I also caught up with James on the top gear motorbike and got him to sign the article in the same issue. We were talking to his dad later on and he mentioned that james was impressed to get some reader feedback and attention!

We left after he started though, so that we could get to hidden valley to check out the solar cars.

I think it is a great concept, and it's good to see manufacturers taking the risk to back up the numbers.

Have a safe trip.

Hi all

Andrea again... Just to let you know we drove from Katherine to Tennant Creek today and the Sportwagon got 6.19l/100km!! 33% increase on our ADR score which for the 3.0l SIDI engine is 9.3l/100km

Tomorrow's trip takes us to Alice

Cheers

Andrea

Thats pretty impressive - hope the balance of the event goes well for you.

Out of interest was the Sportswagon chosen over the sedan as it is more aerodynamic?

Looks like it's going well Andrea - keep the updates coming.

Awsome for the wagon. What was the average speed?

I am interested on what the diesal cruze would do aswell.

Good result as well, is the Maloo entered as well I'm interested to hear how that went if it is.

very nice result there. thats getting to the level of the 4 banggers. what cars run in the 6.2ltr/100km range?

great to see Holden backing up what they say, best way to prove what a great product you have.

what cars has Holden and HSV (if they are running in the event) running? be very interested in seeing the final results compaired to the ADR numbers

As bobgen111 said, wondering average speed and what speed do you cruise the wagon at to get best consumption (I guess this will be similar to the average speed), and why use a wagon rather than a sedan - more a promo thing for the wagon, or expecting a slightly better result with the wagon. Also interested in the diesel cruze result also - Hyundai had a good result with their I30 diesel in this event (last year?). I presume with a 2.0l in the Cruze compared to 1.6 in the Hyundai, that they may get a slightly better result, perhaps the Cruze will get a number close to the Hyundai's.

It is impressive to see how far the solar car technology has progressed since 1987. The winner of the inaugural event would be easily beaten by the cars from 2007. I wonder if they can get from Darwin to Adelaide in less than 30 hours this year.

How the heck does a 6.2L Maloo get down to fuel consumption figures of 5.34L/100km?

I cannot believe 5.34 either.

Another figure quoted is like 7.x which is more believable but still way below anything i have seen on any of my cars (stock or modified).

Even on the straightest flat stretch of roads in 6th gear at 110kmh the best average i ever get is 9.x (over a long distance).

To get to 7.x (let alone 5.34) is a huge % drop in economy.

Great work Andrea, let me know if you need some tips from the crowned "Featherfoot" :lol:

You are joking right?

We all know that UT is the ultimate featherfoot around these parts.

Reading between the lines, it's because of Holden/HSV's dodgy fuel filler pipes. This bit in particular:

“While our figure looks impressive, we aren't getting too excited yet,” he wrote in a daily blog on HSV’s website. “For safety reasons, event organisers aren't brimming [filling the tanks to the top so you can see fuel in the filler neck] each car until the last day."
ie they start with completely full tanks, then fill to the first stop (when there's still about 10L left to go in). eg go 400km on day 1, put 21.36L in to "refill" it, looks like 21.36/(400/100)=5.34L/100km. In reality it's not full, and needs another 10L to fill properly, which gives 31.36/(400/100)=7.84L/100km. (Numbers pulled out of my arse just as a hypothetical.)

Note that on the second day they got 8L/100km, probably because they started with the tank filled to the first stop, and ended by filling it back up to the first stop, ie it was pretty accurate.

This might explain it....

Other issues raised included more consistent refueling. All cars are refueled by the technical director but some cars have had a tendency to take on less fuel in hot conditions than others, and this has in some cases led to wildly unrealistic examples of fuel consumption.

All will be worked out once the cars are brimmed on the final day, however, some teams wanted more consistent fueling each day.

The changes mean the cars won't be refueled until each morning when conditions are cooler and therefore safer.

The funny thing is that the auto is supposed to be more economical than the manual on ADR figures and HSV decide to run the manual? Go figure! :confused:

Aircon on or off? Most of the entrants we saw up here at the start were planning on no aircon. It was also interesting to see which cars had luggage and which ones were just the driver and passenger.

The skoda was fully loaded, and was carrying stuff for the postie bike.

Presume the manual is more economical in these highway conditions, running at optimum speeds for economy (seems they are cruising about 75kmh). While it's interesting to see what can be acheived, and it's good to see Holden and HSV having entries, the results achieved in this run are a long way from realistic real world figures, even for pure highway running. Holden said they are aiming to beat the 9.3l/ 100Km figure, this should be easy really as the 9.3 figure is a combined city/ highway figure, this run has almost no city running. I'm sure they will be able to keep the average for 3.0 wagon under 7.0 l/100 Km average for the whole trip.

The manual can be changed earlier than the auto would keeping revvs down. It also doesn't have to reach a certain speed for the convertor to lock up. At low speeds and auto is like slipping the clutch slightly which is never good for economy. An auto also take slightly more energy to turn than a manual. The ADR figures state a better figure for the auto but I wonder if that is because they have a different diff ratio? I'm not up on new commodore diffs.

[filling the tanks to the top so you can see fuel in the filler neck]
Thats a good way to stuff the carbon canister.

there will be some city driving when they get down to Adelaide mate. so it will give a more realistic figure. but still they have driven 3000km on the highway and not sure how much in Adelaide, but wouldnt be close to 3000km, prob on 500km max to give a random figure.

Exactly and hence you watch the how poor the economy is on the last fill where they have to top it off again.
