fuel consumption/kms per tank - ve v8

[CSP]

It seems to me these newer engines are getting worse. Exclude the V8s here, because obviously you have to compare apples with apples...

Weight, pure and simple.

A VB-VC Commodore weighed only about 1300kg, but they were a smaller car. The VN weighed what? About 1400 or less?
Now we are in the modern 21st century with modern light weight building materials and alloys...and yet a standard six cylinder family car weighs not far off two tonnes...:bang:

No wonder the new Alloytec 190 puts out more power than an SS Commodore of ten years ago...it has to so it is able to lug all the weight around and still give decent performance...the VE SV6 6 speed manual we test drove yesterday went like a cut snake...but I did wonder how much fuel it was sucking while working it up through the gears...:bang:

You really don't have much of an idea about much do you? How much extra safety and comfort features do you think the modern cars have compared with the like of cars from the early 80's and 90's? A LOT!!! The alloys and materials being used are a LOT ligher weight but there's so much more to a car these days. Not to mention the bigger overall size. But with all that has come much more advanced engines and drivelines that use a lot less fuel than earlier models.

Holden are slightly behind the curve when it comes to fuel saving technology like direct injection and the new 6 speed for the V6. When it has those two features, the Alloytec will be as fuel efficient as any other large 6. And a lot more fuel efficent than any model before it.

Any for the record, it hasn't been the Alloytec 190 since the VZ. The VE has had the Alloytec 195 since its release in 2006! You can also drive ANY Holden efficiently. Fuel efficiency depends MOSTLY on how the car is being driven. I can get my V8 LS2 6.0 litre engine to be more efficient than my VE 195kw V6 was if I nanna it around town. With "normal" driving it's about the same but put the boot into it and it sucks the juice. On the highway the V8 wins easily. And you think the V6 goes like a cut snake, drive a V8!

^^^ Not all the metals are lighter in VE, but they're about 50 bazillion times stronger than what they used in the VN I think the weakest metals used in the VE, were the strongest metals used in the VZ or something along those lines. Most of the metals are much stronger and more rigid than what we've seen in a commodore before (structurally that is, not panels).

I doubt the V8 wins easily. Just look at the figures below:

I got from Melb to Syd on one tank in my SV6. Can a VE V8 do that?

 

[1991_Vn2nV]

A tuned 6L will return much better economy than from factory as well.

The alloytec, for a V6, will always be behind the 8 ball on fuel economy. Yes it can add direct injection, 6 speed auto etc... But then so can the Ford 6, and the Toyota 6 (which is under 10L per 100 even without DI).

Another stupid post... Wow! you can quote ADRs which are based on the combined average of city and highway driving. Also, none of your quoted figures include the LS2. Why?

Not that it matters, mine's no longer a standard tune, exhaust or intake. And not ever having driven from Melbourne to Sydney, I can't say personally that I've done it but I have no doubt a V8 will go further than a V6 on the highway... I can drive from Canberra to Sydney and back again and have more than half a tank left - enough to drive around for work etc for two weeks. On the Highway I average about 8 - 8.5 litres per 100km.

I said a V8 would easily be better than a V6 on the highway. Hell, even my 1970 5 litre 308 tri-matic with 600 Holley is better on the Highway than my old VX Commodore S was. It got from Melbourne back to Canberra on half a tank of 95RON fuel.

I can't believe what I am reading!!! A V8 is not more economical than a V6!. My VN SS only got me from Melb to Yass on a tank (80 litre). I am sure a VN V6 would have got me to Sydney on a 80 litre tank. My VX 3.8 got me to Sydney on a tank from Melb.

LOL!!! A properly tuned V8 will always use LESS fuel on the highway than a V6.

And speaking in current technology, I've owned a VE 195kw V6 Calais and a VE 307kw LS2 Clubsport.

The Clubsport uses on average 2 - 4 litres per 100km more fuel aroun town and around 1 litre per 100km less on the highway. I am speaking from first hand experience here...

One of your previous quotes CSP: I get between 14 and 18 litres per 100km around town depending on my driving.
9 flat on the highway.

Slightly different motor though - LS2. With intake, cat back and tune.

73 litre tank, 98RON fuel.

My VE SV6 usually gets around 8 +/- .02 litres per 100km on a country run. Maybe your VE Calais is due for a tune?

 

[CSP]

Don't be an idiot... The Calais hasn't been mine since January 15th.

12 litres per 100km around town in the 195 Alloytec is about normal by the way. between 9 and 10 on the highway... Calais had a few mods though. Your SV6 is stock yeah?

So you are saying that holden cant even tune their cars properly when they leave the factory? needs some backyard mechanic to do some tweaks?
Not really backed up by these:

Fuel Consumption Guide Database 1986-2003 Search Results
yes, ive used 2003 because as you point out they use a 50/50 average of the two cycles for the current models.
Have a think about how low the highway fuel consumption or how high the city cycle would need to be on the current v8 to get an average of 14.3L/100km.

Really, all we have here is the standard v8 petrol head in denial and old wives tales coming through:
ie v8s use less fuel on the highway because they are just loping along
v8s are cheaper to own because the motors last longer because they are less stressed etc.

Neither are true, but if said often enough by the owners they eventually believe their own rhetoric.
