Holden has made fuel-efficiency improvements across its popular V6-powered Commodore range with a model year 2012 update on-sale in mid September.
Commodore Omega sedan, powered by the Australian-built 3.0 litre SIDI V6 engine, achieves new fuel economy of 8.9L/100km, down from 9.1L/100km on the previous model.
Holden has delivered consistent efficiency gains for Commodore since the launch of the VE range in 2006. Fuel economy on the entry-level Omega sedan has improved 18% over the life the model with the addition of Spark Ignition Direct Injection (SIDI) technology, calibration improvements and other weight saving and aero enhancements.
The continued focus on fuel economy means Commodore is still the most fuel-efficient vehicle in the large car segment and is competitive against many popular mid-sized four-cylinder vehicles.
With the model year update all Commodore vehicles will become flex-fuel capable with 3.6L SIDI V6 engine, powering models like the popular SV6, now also able to run on bio-ethanol/E85; a blend of up to 85 per cent ethanol and 15 per cent petrol.
Bio-ethanol is a cleaner burning fuel made in Australia from the waste by-product of wheat and sugar, sorghum and in the future potentially household garbage. It is available at selected Caltex service stations along the eastern seaboard.
Speaking at the Alternative Fuels Summit in Brisbane this week, Holden Chairman and Managing Director, Mike Devereux, said Holden had taken a leadership position in Australia, advocating for and stimulating demand for bio-ethanol.
“The entire Commodore range is now flex-fuel capable, Caltex and other fuel retailers are making high ethanol-blend fuels available and we are working with our consortium partners to build Australia’s first second-generation ethanol plant to turn rubbish into fuel.
“Commodore drivers who run their car on bio-ethanol/E85 can reduce their well-to-wheel CO2 emissions by up to 40% compared to petrol.
“And as well as adding flex-fuel capability, we aim to continuously improve Commodore with every model year. Our engineers and designers are constantly striving to improve fuel efficiency and performance and to enhance the look and feel of the car for our customers.”
The Commodore model year update will also add subtle design enhancements and other features which will be announced closer to start of production this month. A new range of dedicated LPG models will also be launched in early 2012.
“Alternative fuels like bio-ethanol and LPG offer great potential for Australia through reduced CO2 emissions, regional development and energy independence,” Mr Devereux said.
“Bringing more dedicated LPG and flex-fuel vehicles to market will help drive demand for these Australian-made fuels and demystify and make people aware of the benefits they offer.”
