INTRODUCTION
The Ford Falcon FG X 4.0 EcoLPi, launched in 2011 as part of the FG MkII series, was a uniquely Australian offering. The Falcon had been a mainstay of the Australian automotive landscape for decades, and the FG X represented the final major update before the cessation of Australian manufacturing by Ford in 2016. The EcoLPi variant was specifically engineered to run on LPG, a readily available and often cheaper fuel source in Australia. This model aimed to provide a balance between performance, economy, and reduced environmental impact, appealing to fleet buyers and private owners alike. It sat in the middle of the Falcon range, offering a more affordable alternative to the petrol V8 while providing more power than the base four-cylinder engine.
Powertrain & Engine Architecture
The heart of the Falcon FG X EcoLPi is the Barra 4.0-liter inline-six engine, specifically adapted for LPG operation. Designated the Barra EcoLPi, this engine shares its basic architecture with the petrol Barra engines but features significant modifications to accommodate the different combustion characteristics of LPG. These changes include hardened valve seats, a revised combustion chamber design, and a fuel injection system optimized for gaseous fuel. The engine utilizes multi-point fuel injection, delivering LPG directly into the intake ports. The engine produces 269 horsepower at 5000 rpm and 409 Nm (301.66 lb-ft) of torque at 3250 rpm. The engine is paired with a six-speed automatic transmission, providing smooth and efficient gear changes. This transmission was a key component in maximizing fuel economy and drivability.
Driving Characteristics
The Falcon FG X 4.0 EcoLPi offered a comfortable and capable driving experience. While not as overtly sporty as the V8-powered Falcons, the EcoLPi provided ample power for everyday driving and highway cruising. The automatic transmission was well-tuned, offering responsive shifts and a smooth power delivery. Compared to the manual transmission versions, the automatic prioritized ease of use and convenience. Against the petrol six-cylinder, the EcoLPi offered comparable performance, but with the added benefit of lower fuel costs. The six-speed automatic transmission helped to keep the engine in its optimal power band, providing good acceleration and responsiveness. The rear-wheel-drive configuration contributed to a balanced feel, although it wasn’t designed for aggressive cornering.
Equipment & Trim Levels
The FG X 4.0 EcoLPi was typically offered in a well-equipped package, often including features such as air conditioning, power windows and mirrors, a multi-function steering wheel, and a basic audio system. Higher trim levels added features like alloy wheels, fog lights, a more advanced audio system with a touchscreen display, and parking sensors. Interior upholstery was generally cloth, with leather options available on some trims. The EcoLPi variant often targeted fleet buyers, so standard equipment focused on practicality and comfort rather than outright luxury. Optional extras included a sunroof, upgraded sound systems, and satellite navigation.
Chassis & Braking
The Falcon FG X utilized a robust chassis and suspension setup. The front suspension featured double wishbones, while the rear employed an independent multi-link design. This configuration provided a good balance between ride comfort and handling. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard, enhancing safety and control. The suspension was tuned to provide a comfortable ride, but it also offered reasonable handling characteristics for a large sedan. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The Falcon FG X 4.0 EcoLPi was generally well-received in the Australian market, particularly by those seeking a cost-effective and environmentally conscious vehicle. Critics praised its fuel efficiency and smooth driving experience. Compared to the petrol-powered Falcons, the EcoLPi offered lower running costs, but some noted a slight reduction in overall performance. Against competitors like the Holden Commodore, the Falcon EcoLPi offered a unique proposition with its dedicated LPG engine. The EcoLPi’s fuel economy was a key selling point, especially given the fluctuating prices of petrol in Australia. Reliability was generally good, although LPG systems can require more frequent maintenance than petrol engines.
Legacy
The Ford Falcon FG X 4.0 EcoLPi represents a unique chapter in Australian automotive history. As one of the last Falcons produced in Australia, it holds a special place in the hearts of many enthusiasts. The EcoLPi powertrain, while now somewhat dated, demonstrated Ford’s commitment to alternative fuels and reducing emissions. In the used car market, these Falcons are becoming increasingly collectible, particularly well-maintained examples. The long-term reliability of the Barra EcoLPi engine is generally good, but regular servicing and maintenance are crucial to ensure its continued performance. The EcoLPi variant remains a practical and affordable option for those seeking a spacious and comfortable sedan with lower running costs.
