The higher spec holden engine, producing more power, is obviously not tuned for economy but more power. What would be the result if holden put their 5 speed auto into the omega, with the lower tune engine?

And BTW I think that FG engines are actually lighter than BF engines – Ford mention lightweight materials for ancillaries.

so perhaps this is why they use more fuel as well as having move power than the Omega alone.
The Ford base model XT use a 4 speed and is similar weight (1704 kg) as the omega, but has a better fuel economy.
Is it because of the Ford 4 speed has different ratio setup?

The 5speed autos in the SV6 and Calais V6 have the higher output engine (190 kw). The Omega and Berlina have the 4speed auto have the (175 kw).So naturally the SV6 and calais will use more fuel. Also the Sv6 and Calais are meant to use PULP.

Crazychook, the SV6 and V6 Calais has a 195kW engine as standard not 190kW! And the base-line Omega has 180kW not 175kW Crazychook!

Holden’s 5 speed high outout V6s shouldn’t use more fuel than the 4 speed auto versions based on higher power alone.
I do believe the calais and SV6s are heavier than the base omega, then again higher spec FG’s are heavier than base model XT also.

Holden needs a base 5 speed and higher end 6 speed in it’s V6s NOW.

I find it odd also that the 5speed auto Ve’s take more fuel than the 4speed versions.

The 5 speed autos have the more powerful HF V6, maybe that has something to do with it??

All i know is FG is considerably more fuel efficient than VE’s particuarly the 6 speed auto falcons.

Falcon G6E: 10.1 L/100km
Calais: 11.3 L/100km

Thats almost $2 extra for every 100km for the Calais. (or nearly $500 a year, every year)

The 10.9l/100klm figure is combined city/highway for the 4 speed auto, Fg falcon is 10.5l/100klm and 10.1l/100klm for 6 speed auto.
Remember the Mazda 6 takes premium unleaded fuel, not standard.

I agree in general about fuel consumption but remember to look at the top 10 sellers and the market has fragmented.

A rav-4, CRV, X-trail 4cyl models aren’t much better for fuel use, while a V6 aurion, camry and V6 rav-4 are the same.

Those 2 vehicles are simply no the two top seling vehicles any longer, perceptions play a big part in the fuel consumption story.
Fuel consumption isn’t the most expensive aspect of vehicle ownership also.

The reality is people are still buying gas guzzlers, just a different breed is all.

I could be wrong, but the 4 speed auto in Commodore makes for higher fuel consumption.

As has been mentioned many times, fuel prices aren’t the bullet in the hearts of falcon and commodore. These 2 are actually on par with many vehicles for fuel consumption.

Buyer tatses have changed more specifically.

yay, someone understands!

Hello! ford will be exporting focus production, Toyota didn’t export local corolla production, see the difference?

Years ago, the large car market was stronger, see the difference?

It also depends on each individual car makers plans on where they produce and seemble vehicles around the world.

Shall i keep repeating until some understand?

im sure holden/GM saw the trend for smaller cars coming. they just got the next step wrong (in australia at least). they assumed that meant people wanted a cheap car (daewoo). id say they are lookign for somethign more practical (price, running costs, size, environment). even americans are downsizing, and look at europe!! with 90%+ people in australia in the major cities you can see why its happening.
