The Opel Adam 1.4 ECOFLEX (87 hp) LPG, produced from 2013 to 2018, was a subcompact hatchback marketed primarily in Europe. It represented a key variant within the first generation of the Adam (A14), Opel’s attempt to capture a younger, more style-conscious audience in the competitive city car segment. This particular version combined a naturally aspirated 1.4-liter petrol engine with the option of Liquefied Petroleum Gas (LPG) conversion, paired with a five-speed manual transmission. It occupied a mid-range position in the Adam lineup, offering a balance between affordability, fuel efficiency, and reasonable performance. The Adam, in general, was designed to be highly customizable, allowing buyers to personalize their vehicle with a wide array of colors, trims, and accessories.

Powertrain & Engine Architecture
The heart of the Adam 1.4 ECOFLEX LPG is the A14XEL engine, a 1398cc inline-four cylinder petrol engine. This engine belongs to Opel’s Family 0 small engine family. It utilizes a multi-point fuel injection system and a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. The engine’s design prioritized fuel efficiency and low emissions, hence the “ECOFLEX” designation. The LPG conversion is typically a factory-installed option, utilizing a dedicated LPG tank and fuel system that operates alongside the petrol system, allowing the driver to switch between fuels. The five-speed manual transmission was the standard offering for this variant, providing a relatively direct and engaging driving experience. The transmission’s gear ratios were tuned for urban driving and fuel economy, rather than outright performance.
Driving Characteristics
The 87 hp output and 130 Nm of torque delivered by the 1.4 ECOFLEX engine, even with the LPG system, resulted in modest performance. Acceleration from 0-60 mph took around 12.3 seconds, and the top speed was approximately 109 mph. Compared to higher-output Adam variants, such as those with the 1.4 Turbo engine, the 1.4 ECOFLEX felt noticeably slower, particularly during overtaking maneuvers. However, the LPG system offered a slight reduction in running costs, and the engine proved reasonably responsive within its limited power band. The manual transmission allowed for greater driver control, but the gear ratios were spaced to prioritize fuel economy over spirited driving. The overall driving experience was best suited for city commuting and shorter journeys.
Equipment & Trim Levels
The Adam 1.4 ECOFLEX LPG typically came with a base level of equipment, focusing on practicality and affordability. Standard features included air conditioning, power steering, electric front windows, and a basic audio system. Safety features such as ABS and front airbags were also standard. Higher trim levels, such as ‘Glam’ or ‘Slam’, offered additional features like alloy wheels, upgraded interior trim, a touchscreen infotainment system, and various styling enhancements. The Adam was particularly known for its extensive customization options, allowing buyers to choose from a wide range of exterior colors, roof designs, and interior accents.
Chassis & Braking
The Adam utilized a MacPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, well-suited for urban roads. The braking system consisted of disc brakes on the front wheels and drum brakes on the rear wheels. While adequate for everyday driving, the braking performance was not particularly sporty. The Adam’s relatively lightweight construction (around 1103 kg) helped to mitigate the limitations of the braking system. The steering was light and precise, making it easy to maneuver in tight spaces.
Market Reception & Comparison
The Opel Adam 1.4 ECOFLEX LPG was generally well-received as an affordable and fuel-efficient city car. Critics praised its stylish design and extensive customization options. However, the engine’s limited power output was a common criticism. Compared to other Adam variants, such as the 1.4 Turbo, the ECOFLEX LPG offered lower performance but better fuel economy and lower running costs, especially when utilizing the LPG system. It competed with other subcompact hatchbacks like the Fiat 500, Volkswagen up!, and Peugeot 108.
Legacy
The A14XEL engine, while not known for being exceptionally durable, proved to be reasonably reliable in the Adam. Common issues included occasional oil leaks and sensor failures. The LPG conversion, if properly maintained, added to the engine’s longevity. Today, the Adam 1.4 ECOFLEX LPG can be found on the used car market at relatively affordable prices. It remains a popular choice for those seeking a stylish and economical city car, particularly in regions where LPG is readily available and cost-effective. Its customizable nature and relatively simple mechanicals make it an appealing option for budget-conscious buyers.
