    Default New Holden Commodore Omega range boosts economy with new 3.0 and 3.6L V6 engines

    AUSTRALIA's best selling family car has just gotten cheaper to run, with the new six-cylinder motor delivering the economy of four cylinders.
    Holden says a family will now be able to drive from Melbourne to Sydney on a single tank with its new Omega fleet.

    GM-Holden has announced the revised Commodore range will get two new direct injection engines that promise significant fuel savings and lower CO2 emissions.



    The 3.0-litre and 3.6-litre V6 engines will be available with the new VE Mk II update from next month, as well as the Statesman/Caprice lineup.

    Both engines deliver better power but with direct injection, the economy of a four cylinder.

    The company's outgoing chairman and managing director, Mark Reuss, says the engines have real-world savings.

    “We've been listening to what the customer wants,'' he says.

    Importantly there will be no price increases on most models, he says.

    Commodore buyers will be able to save up to $325 a year in fuel costs, based on travelling 20,000km.

    The new entry Omega fleet 3.0-litre model achieves 9.3 litres/100km, more than 13 per cent better than the existing model's 10.7 litres/100km.

    “That means you can drive from Melbourne to Sydney on one tank,'' Reuss says.

    “We know because we've done it.''

    Reuss says the engine is more efficient than some four cylinder competitors.

    A new six-speed transmission will also be standard on petrol sedan, wagons and the SV6 ute.

    Reuss says the savings come through hi-tech technology called Spark Ignition Direct Injection, a first for a locally built vehicle.

    The all new 3.0-litre SIDI engine will power the Omega and Berlina sedan and wagon.

    The larger 3.6-litre SIDI engine will go into Holden's premium Commodore range, including the SV6, Calais and Calais V-Series, as well as the SV6 ute and Statesman and Caprice.

    The 3.6-litre engine's fuel economy improves between 7 and 13 per cent.

    All SIDI engines also get more power.

    The 3.0-litre develops 190kW, up from 175kW of the previous engine, while the 3.6-litre develops 210kW, up from 195kW.

    Holden's popular dual-fuel LPG range will retain the 3.6-litre AlloyTec V6 but it has been reworked to life economy and reduce CO2 emissions.

    An LPG-equipped Omega sedan now consumers 13.4l/100km, down from 14.2l/100km, a 6 per cent reduction.

    CO2 emissions come down 6 per cent from 230 g/km to 217 g/km

    They've got to be kidding. How much does that thing weigh? I get that sort of economy in peak hour with my 20-year-old V8.

    Yeah. Im pretty sure you consume more gas than normal petrol but its much cheaper. that wouldn't be petrol consumption, it would be gas

    correct me if im wrong

    About 350Nm. This engine is watered down something bad. Stock form it should be 230kw 375nm. But guess its looking at economy first.


    The big winner is the 3.6lt V6 in the calais. Same price as before, more power torque and 6 speed auto, all in a 9.9l/100 economy.

    Yeah but thats 50cpl compared to 120cpl You use more LPG than you do petrol, but it still works out cheaper per 100km.

    Just to clarify,

    3.6 L SIDI is - 210 Kw and 350 Nm of torque
    Fuel economy 10.1 - 10.3 L/100 KM (Im guessing it depends on spec and if auto or manual)

    3 L SIDI is - 190 KW & 290 Nm torque (a substantial loss of torque)
    Fuel economy is 9.3 L/100 KM

    Hopefully the 6 speed auto will help make up for the lack of torque in the 3 litre.

    Looks like that headers are a no go with the new V6's... But i'm wondering if both versions of the V6 have the manifolds cast into the heads.

    The 3.6 LLT motor is what's in the 2010 Buick LaCrosse. We need the 2010 Camaro engine specs. 227Kw@6400 and 370Nm@5200.

    i dont believe the manifolds were that different, it has a high pressure fuel pump on the back of the left hand head, and still runs fuel rail and injectors under the rail

    9.3 L/100km is awesome for a car it's size. i wonder what the 0-100 times though.
    no point having a commodore use fuel like a camry then go like a camry..

    About half an hour..

    Nah maybe high 8's mid 9's, similar to now, as long as they get the gearing right it should pull ok.

    Be ok with we could see this engine in action on another overseas model.

    how have they gotten less power, just detuned them, if thats the case stands to reason people could simply get them retuned to 227kw

    It's all just smoke and mirrors, none of these figures are for the real world consumption. You can get good fuel economy out of most car it just comes down to how you drive them!

    I'm all fore the greener engines but I also like performance. More power results in less right foot (for the majority) and thus reflects decent fuel economy.
    I dearly hope that the Holden engineers get their power to weight ratio's right to complement the new transmission ratio's which are probably left untouched from the higher output engines in the US.
    I've already read of motoring industry individuals that have designated the new 3ltr engine as a lemon purely because of torque values quoted. Maybe, or are they just holden bashers and drive uninspiring euro trash
    I too wish we were getting the US spec engines as they get a good rap from the yank tests. The 6 speed auto also has some good reliability stats in the US.

    Reducing the KW power of the 6ltr is also distressing

    hopefully they gave an extra 2 multipling gears instead of a overdrive + mutliply,

    if they say first gear is like 4.5:1+ it will be the same if not a fraction better than the current 4sp,

    thats if they keep the 3.27:1 diff ratio

    I'm interested in this weight reduction they speak of. They have said the motor and auto reduce weight on their own. But what more can they do to drop another 50 od kg.

    Some detials..

    TRANSMISSION 6L50E
    TransmissionType: Electronically controlled automatic overdrive transmission with torque converter clutch. Clutch to clutch architecture with integral Electro/ Hydraulic controls module
    Gear ratios: (:1):
    First: 4.06
    Second: 2.37
    Third: 1.55
    Fourth: 1.16
    Fifth: 0.85
    Sixth: 0.67
    Reverse: -3.2
    Final drive ratio: 3.27

    hmm interestin ratios, i hope it does go allright, i can imagine alot of cog swapping on the freeway though


    i also see what was said earlier about the exhaust manifold.....

    on the 3.0 they appear to be using a single port outlet.....


    and they are using a plastic intake manifold on them now

    I hope it goes good with them ratio.. Mum and dad will drive them like a 4 cylinder, we might not, but that's why the 3.6lt is overall the most impressive keeping power and adding economy.

    Cadillac uses this motor and auto in the CTS. It's a heavier car, and they say our version is better on fuel.
    Performance wise i still don't know ?. But that would be a good place to start. Does anyone have knowledge of that car at all ?.
