Wait till you drive an SIDI. Chaulk and cheese, it is a huge step forward.

Let's hope you didn't design the badges for them mr love .... Halden Commadoor!

Is this the same principle as windsurfing marketing? "We got it so wrong last year, but this years kit is perfect"... followed by "Last year was a mistake, this year we finally got it right!"?

what mr love was saying is that the new holden engine is completely different and a new technology.

ie. say goodbye to spark plugs. the new petrol engines will use deisel technology and have economy better than anything seen before.

Sorry, I was taking the piss out of his spelling mistake of 'chaulk'. I guess designers don't need to spell, they just need to be able to draw.

As for "say goodbye to spark plugs. the new petrol engines will use deisel technology and have economy better than anything seen before"; are you really sure about that?

If they don't have spark plugs, I will be very very very very very very very very very surprised. If they go so far as to omit the sparkplugs and rely on diesel technology, then it is, you got it, a diesel! - whether it uses 'diesel' fuel or petrol. Of course, we know that petrol will detonate well before a diesel engine needs it to, so you can't use petrol in this way.

I guessed this from the name, (and I just googled it too), but the SIDI is just injecting the fuel into the cylinder instead of the intake. This method is similar to how a modern diesel engine gets its fuel, but there still is a conventional spark plug sitting there, doing the usual thing.

I think it is a typical marketing speak to describe this as completely different and new technology, but hey, what good is a good design without being able to sell it.

I agree with the fact that it seems to get good economy though, which can't be a bad thing.

We are missing the most obvious point though... why is the wagon shorter, and when is the long wheel base panel van version coming out?

Correct, designers don't know how to spell (or type with more than 2 fingers) If you can spell you get sacked, obviously spent too much time in class paying attention instead of drawing!!!

Hi, All,

SIDI stands for Spark Ignition, Direct Injection. On SIDI engines, the injectors now inject fuel directly into the combustion chamber where the spark ignites it. On non-SIDI engines, the injectors inject fuel into the inlet manifold where it is drawn into the combustion chamber where the spark ignites it.

You can Google "Holden, SIDI" for further explanation and videos.

Hope this helps.

i think for now yes there is still a spark plug. but it is new technology and i am told from some very very reliable people that the intention is that down the track the "petrol" will be pumped into the chamber under extremely high pressure and like a deisel engine will combust due to heat and not via a spark plug. whether there is a permanent glo plug or not i am not sure. but it ain't a deisel cause it uses petrol.

speaking of designers, i once spelt the name of a building wrong so all of the signage went up incorrect. was some awkward moments on opening day.

Hmmmm, I am not so sure about that. My understanding is that the flash point of petrol is far too low to ever be used this way. This would make petrol too difficult to control.

I would also ask why? If the internal combustion process in the engine is the same then I would assume the petrol powered engine will be less powerful, as diesel has a higher energy content.

Yeah, that sounds interesting, and it sounds like they are still working on that technology. On the example engine that they describe it needs spark plugs under some conditions anyway, though I guess any start in a new direction is going to take some time to refine.

I wonder how much more efficient it needs to be than a conventional engine to justify the extra components and the noise that this technology generates.

I think the best way to make a new commodore or falcon run smoother is to get an original VN V6 commodore and drive that round for a while. Jump into the newer car and you won't even think the engine is turned on.

Mazda 6 wagon here. 3 boards, 3 masts, 3 sails, 2 booms all in the car. (OK 1 mast on the roof, coz it's now fuzed into a single piece 460)

As paddymac said, the 60/40 split is set up correctly on the Mazda - single seat behind the driver.

Pretty economical 2.3 litre 4cyl engine too. Much smaller than the Fords/Holdens but still grunty enough for the highway. I'll let DavMen review the current model...

i do like the holden wagon V6, (2000 model i think is mine?) 60/40 split with 40 behind driver.

it's been very reliable and fits everything easily. great to drive also. does step out in the back end around round abouts easily.

the most kit i've put in and on it is.

familly of 5 with luggage for a week, inflatable boat, motor and petrol, bed linen for family plus food for a week.

3 boards
5 masts
5 sails
2 boxes of bits
3 booms
10 fins

sandpit toys, dvd player, camera gear, laptop and on and on.

some carefull packing and the thing is a bottomless pit.

Did you do the stripe? Want a job at Holden Design ? Ha!!!!
