The Chevrolet Onix 1.4, specifically the variant equipped with the 98/106 horsepower engine and a six-speed automatic transmission, was a key model in Chevrolet’s South American lineup from 2013 to 2016. Positioned as a mainstream, affordable hatchback, the Onix aimed to capture a significant share of the growing Brazilian and Argentinian automotive markets. This particular configuration represented a balance between fuel efficiency and usability, targeting buyers who preferred the convenience of an automatic transmission without sacrificing too much performance. It was part of the first generation (Onix I) built on General Motors’ global Gamma platform, also underpinning models like the Opel Corsa and Chevrolet Prisma/Onix Plus sedan.

Powertrain & Engine Architecture
The Onix 1.4 utilized the SPE/4 engine, a 1.4-liter inline-four cylinder engine designed to run on both gasoline and ethanol (or any blend thereof). This “flex-fuel” capability was crucial in Brazil, where ethanol is a widely available and often cheaper fuel source. The engine featured a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. Multi-point fuel injection delivered fuel to the cylinders. The key difference between the 98 hp and 106 hp outputs was the engine control unit (ECU) calibration, optimized for either gasoline or ethanol respectively. When running on ethanol, the higher compression ratio and fuel’s inherent properties allowed for increased power. The six-speed automatic transmission was a crucial component, offering a smoother driving experience than the available five-speed manual. While not a particularly sophisticated transmission, it was reliable and well-suited to the engine’s torque characteristics.
Driving Characteristics
The 1.4L automatic Onix offered adequate, but not exhilarating, performance. Acceleration from 0-60 mph took around 12.1 seconds, making it suitable for city driving and highway cruising, but not for spirited driving. The automatic transmission, while convenient, did contribute to some power loss compared to the manual version. Gear ratios were tuned for fuel economy, meaning the engine often operated at higher RPMs during acceleration. The flex-fuel capability provided a noticeable boost in power when running on ethanol, but at the cost of slightly reduced fuel economy. The suspension was tuned for comfort, providing a relatively smooth ride over uneven road surfaces, typical for the region’s infrastructure.
Equipment & Trim Levels
The Onix 1.4 automatic typically came with a base level of equipment, including air conditioning, power steering, power windows, and a basic audio system with USB connectivity. Higher trim levels, such as the LT and LTZ, added features like alloy wheels, fog lights, a more advanced audio system with Bluetooth, and remote keyless entry. Interior upholstery was typically cloth, with options for different color schemes. Safety features included dual front airbags and ABS brakes as standard equipment. Optional extras included parking sensors and a rearview camera, which were becoming increasingly popular at the time.
Chassis & Braking
The Onix utilized a McPherson strut front suspension and a torsion beam rear suspension. This setup provided a good balance between ride comfort and handling. The front brakes were ventilated discs, while the rear brakes were drum brakes – a cost-saving measure common in this segment. ABS (Anti-lock Braking System) was standard, enhancing safety during emergency braking situations. The steering was hydraulic power-assisted, providing a reasonably light and responsive feel.
Market Reception & Comparison
The Chevrolet Onix was generally well-received in the Brazilian and Argentinian markets. Critics praised its modern styling, spacious interior, and competitive pricing. The 1.4L automatic variant was seen as a practical choice for buyers who prioritized convenience and fuel efficiency. Compared to other models in its class, such as the Fiat Palio and Volkswagen Gol, the Onix offered a more modern design and a more refined interior. However, some critics noted that the engine lacked power, especially when running on gasoline. Fuel economy was competitive, but not class-leading. Reliability was generally good, although some owners reported minor issues with the automatic transmission.
Legacy
The Chevrolet Onix proved to be a hugely successful model for Chevrolet in South America, consistently ranking among the best-selling cars in the region. The 1.4L automatic variant, while not the most powerful or sporty version, played a significant role in the Onix’s success by appealing to a broad range of buyers. In the used car market, these Onix models are generally considered reliable and affordable, making them a popular choice for first-time car buyers or those seeking a practical and economical hatchback. The SPE/4 engine, while not known for its complexity, has proven to be relatively durable with proper maintenance. The Onix’s success paved the way for the second generation model, which continues to be a popular choice in South America today.
