The Chevrolet Onix II Plus 1.0T, produced from 2019 to 2025, represents a significant iteration of Chevrolet’s popular compact sedan in the South American market, particularly Brazil. Positioned as a mid-range offering within the Onix II Plus lineup, the 1.0T variant aimed to bridge the gap between the base 1.0L naturally aspirated engine and the more powerful 1.2L turbo. Built on the GM GEM platform, the Onix II Plus sought to deliver a blend of fuel efficiency, modern features, and a comfortable driving experience for the value-conscious consumer. This specific configuration, with its 1.0-liter turbocharged engine and five-speed manual transmission, became a mainstay for buyers seeking a balance between performance and economy.

Powertrain & Engine Architecture
The heart of the Onix II Plus 1.0T is the GM Family I three-cylinder engine, specifically the X10XE variant. This 999cc engine utilizes a single-scroll turbocharger with an intercooler to boost power output to 116 horsepower at 5,500 rpm and 160 Nm (118 lb-ft) of torque at 2,000 rpm. The engine employs multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration allows for a relatively broad torque curve, making the engine responsive in everyday driving situations. The five-speed manual transmission was the standard offering for this trim, providing a direct connection between the engine and the front wheels. The transmission’s gear ratios were tuned for a balance of acceleration and fuel economy, with a relatively tall fifth gear for highway cruising.
Driving Characteristics
The Onix II Plus 1.0T offered a noticeable step up in performance compared to the naturally aspirated 1.0L version. While not a sports car, the turbocharger provided a useful boost of power for overtaking and merging onto highways. The five-speed manual transmission allowed drivers to maintain control over the engine’s powerband, although the turbo lag was perceptible at lower engine speeds. Compared to the higher-spec 1.2L turbo variant, the 1.0T felt less refined and had a slightly coarser engine note. However, the lighter weight of the 1.0T engine contributed to a more nimble feel in city driving. The gear ratios were well-matched to the engine’s torque curve, providing adequate acceleration in most situations.
Equipment & Trim Levels
The Onix II Plus 1.0T typically came equipped with features such as air conditioning, power steering, power windows, and a basic audio system with Bluetooth connectivity. Higher trim levels within the 1.0T range added features like alloy wheels, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and rear parking sensors. Interior upholstery was typically cloth, with a straightforward dashboard layout. Optional extras included a rearview camera, automatic headlights, and rain-sensing wipers. The overall interior design prioritized functionality and durability over luxury.
Chassis & Braking
The Onix II Plus utilized a McPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. The front brakes were ventilated discs, while the rear brakes were drums. ABS (Anti-lock Braking System) was standard equipment. The steering was a rack and pinion system, providing reasonably precise steering feel. The suspension was tuned for comfort and stability, prioritizing ride quality over handling precision. Stabilizer bars were included to reduce body roll during cornering.
Market Reception & Comparison
The Chevrolet Onix II Plus 1.0T was generally well-received by Brazilian consumers as a practical and affordable compact sedan. Critics praised its fuel efficiency and modern features, but some noted the engine’s lack of refinement compared to competitors. Compared to the 1.0L naturally aspirated version, the 1.0T offered a significant performance improvement for a relatively small price increase. Compared to the 1.2L turbo, the 1.0T was more affordable but offered less power and refinement. Fuel economy was a strong point, with the 1.0T achieving competitive figures in its class. Reliability was generally good, with few reported issues with the engine or transmission.
Legacy
The Chevrolet Onix II Plus 1.0T remains a popular choice in the used car market in Brazil. Its combination of affordability, fuel efficiency, and modern features has made it a desirable option for budget-conscious buyers. The 1.0T engine has proven to be relatively reliable, with proper maintenance. While the Onix II Plus has since been replaced by newer models, the 1.0T variant continues to be recognized as a significant contributor to Chevrolet’s success in the South American market. Its enduring popularity is a testament to its practicality and value proposition.
