Holden announced

Also announced at the 2008 motor show was a version of the 6.0 litre V8 engine fitted with Active Fuel Management (AFM) technology, known as the L76. Originally omitted from the L98 V8, AFM aids fuel consumption under light engine loads, although it is available only when paired with the automatic transmission and power output is reduced by 10 kilowatts (13 hp).[55] The announcement of AFM coincided with the announcement of EcoLine, a badge highlighting Holden vehicles employing fuel saving technologies or those powered by fuels other than petrol. For the VE Commodore, both AFM and LPG-powered versions fall under the EcoLine umbrella.[56] On 7 April 2009, Holden announced that dealerships were receiving their first deliveries of EcoLine-branded models.[57]

On 4 August 2009, Holden announced the MY10 revisions to the VE and WM range to be released in September.[58] For the VE Omega and Berlina, the 3.6 litre Alloytec V6 has been downsized to 3.0 litres, the lowest engine displacement of a Commodore since the straight-six engine fitted to the 1986 VL series. This smaller capacity engine features Spark Ignition Direct Injection (SIDI) technology, and is officially claimed to reduce fuel consumption by up to 12 percent depending on the variant. Power increases to 190 kilowatts (250 hp), although torque is reduced to 290 newton metres (210 ft·lbf).[59] Along with the 3.0 litre engine, a 3.6 litre version of the same, producing 210 kilowatts (280 hp) and 350 newton metres (260 ft·lbf), was also unveiled. Other than the manual transmission version of the SV6, all SIDI V6 models are coupled to GM's 6L50 automatic and fall under Holden's EcoLine banner.[60] Benefits to fuel economy can also be attributed to an improved "deceleration fuel cut" system, which terminates the fuel supply during engine coasting; a higher efficiency alternator and voltage regulator; a 50 rpm lower idle speed (to 550 rpm); and a new "turbine damper" for the automatic transmission that works to suppress vibrations at low rpms, thus enabling earlier upshifts.[61] Omega versions of the Ute and all bi-fuel versions retain the existing 3.6 litre and four-speed automatic combination, although the LPG engine has been tweaked for further efficiency gains.[
