The Opel Corsa D 5-door 1.4i 16V LPG ecoFLEX, producing 90 horsepower (87 hp on LPG), was a variant of the fourth-generation Corsa (D) produced between July 2009 and November 2010. Positioned as an economy-focused option within the Corsa D range, it aimed to provide a lower cost of ownership through the addition of a dedicated Liquefied Petroleum Gas (LPG) system alongside conventional gasoline operation. This model was primarily sold in European markets, where LPG infrastructure was more established and government incentives often favored alternative fuel vehicles.

INTRODUCTION
The Corsa D, launched in 2006, represented a significant step forward for Opel’s small car offering. The 1.4i 16V LPG ecoFLEX variant, introduced in 2009, was a response to growing environmental concerns and fluctuating fuel prices. It was built on the GM’s global Gamma platform (1HX0/A3), shared with other models like the Fiat Grande Punto and the Opel/Vauxhall Meriva. The ecoFLEX designation indicated Opel’s commitment to fuel efficiency and reduced emissions, achieved through a combination of engine optimization and the addition of an LPG conversion.
Powertrain & Engine Architecture
At the heart of the Corsa D 1.4i LPG ecoFLEX lies the Z14XEP engine, a 1.4-liter inline-four cylinder gasoline engine. This engine utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports. The engine features a double overhead camshaft (DOHC) valvetrain, operating 16 valves (four per cylinder) to optimize airflow and combustion efficiency. The LPG system is a dedicated conversion, meaning it operates on LPG when available and automatically switches to gasoline when the LPG tank is empty. The engine management system is calibrated to handle both fuel types seamlessly. The 5-speed manual transmission was the only gearbox option available with this engine, prioritizing fuel economy over outright performance.
Driving Characteristics
The 90 horsepower output and 125 Nm (92.2 lb-ft) of torque delivered by the 1.4i LPG engine resulted in modest, but adequate, performance. Acceleration from 0-60 mph took around 11.8 seconds, and top speed was approximately 107.5 mph. On LPG, power dropped slightly to 87 hp, and acceleration increased to 12.6 seconds for 0-62 mph. The gear ratios in the 5-speed manual transmission were geared towards economy, meaning the engine needed to be revved to access its power. Compared to the more powerful 1.6-liter versions of the Corsa D, or even the diesel variants, the 1.4i LPG felt noticeably slower, particularly when fully loaded or tackling inclines. However, the LPG system provided a smoother, quieter operation compared to gasoline, and the lower fuel costs were a significant benefit for high-mileage drivers.
Equipment & Trim Levels
The 1.4i 16V LPG ecoFLEX trim typically represented an entry-level or mid-range offering within the Corsa D lineup. Standard equipment generally included central locking, power steering, electric front windows, and an ABS anti-lock braking system. Interior upholstery was typically cloth, and the dashboard featured a basic, functional design. Optional extras could include air conditioning, alloy wheels, a CD player with MP3 compatibility, and parking sensors. The focus was on providing a practical and affordable vehicle, rather than luxurious appointments.
Chassis & Braking
The Corsa D utilized a McPherson strut front suspension setup, providing a comfortable ride and predictable handling. The rear suspension employed a torsion beam arrangement, which was cost-effective but less sophisticated than a fully independent setup. The front brakes were ventilated discs, offering good stopping power, while the rear brakes were solid discs. The steering was rack and pinion, providing precise control. The 185/65 R15 tires offered a good balance between comfort and grip. The relatively lightweight nature of the Corsa D (1163 kg / 2563.98 lbs) helped to offset the modest engine output.
Market Reception & Comparison
The Corsa D 1.4i LPG ecoFLEX was generally well-received by critics as a sensible and economical choice. Its primary appeal lay in its lower running costs, thanks to the cheaper price of LPG compared to gasoline. Fuel economy on gasoline was around 38.6 US mpg, while LPG consumption translated to comparable savings depending on local fuel prices. Compared to the 1.6-liter gasoline versions, the 1.4i LPG offered lower performance but significantly better fuel economy. The diesel variants provided even better fuel economy, but came with a higher purchase price and potential maintenance costs. Reliability was generally good, although the LPG system required periodic servicing to ensure optimal performance.
Legacy
The Opel Corsa D 1.4i 16V LPG ecoFLEX remains a relatively common sight on European roads today. The Z14XEP engine is known for its durability, and the LPG system, when properly maintained, can provide many years of reliable service. In the used car market, these models are often sought after by budget-conscious buyers looking for a practical and economical runabout. While not a performance icon, the Corsa D 1.4i LPG ecoFLEX represents a pragmatic solution for drivers seeking to reduce their fuel costs and environmental impact.
