The Chevrolet Trax, known as the Holden Trax in some markets like Australia and New Zealand, is a subcompact SUV first introduced by Chevrolet in 2013. The first generation, designated the Trax I, underwent a significant facelift in 2017, bringing updated styling and revised features. This article focuses specifically on the 2017-2022 Chevrolet Trax I equipped with the 1.4-liter turbocharged engine paired with a six-speed automatic transmission. This configuration represented a mid-range offering within the Trax lineup, positioned between the base model and potentially higher trim levels with more extensive feature packages. The Trax aimed to provide an affordable and practical entry point into the burgeoning subcompact SUV segment, particularly appealing to first-time buyers and those seeking a versatile urban vehicle.

Powertrain & Engine Architecture
The 2017-2022 Chevrolet Trax 1.4L Automatic utilizes the LUW engine code, a 1.4-liter inline-four cylinder gasoline engine. This engine is part of General Motors’ Small Engine Family (SEF) and features a single overhead camshaft (SOHC) valvetrain with four valves per cylinder (DCVDP). A key feature is its turbocharging, employing a low-inertia turbocharger and intercooler to boost power and efficiency. Fuel delivery is managed by a multi-port fuel injection system. The engine produces 140 horsepower at 4900-6000 rpm and 200 Nm (147.51 lb-ft) of torque between 1850 and 4850 rpm. The six-speed automatic transmission, often designated 6T40 or similar, is a conventional hydraulic automatic with electronically controlled shifting. It’s known for its relatively smooth operation, but isn’t particularly sporty in its shift programming. The transmission is geared towards fuel efficiency and comfortable cruising rather than aggressive acceleration.
Driving Characteristics
The 1.4L turbocharged engine and six-speed automatic combination in the Trax delivers adequate, though not exhilarating, performance. Acceleration from 0-60 mph takes approximately 9.2 seconds. The turbocharger provides a noticeable boost in power during mid-range acceleration, making it suitable for merging onto highways and passing slower traffic. However, the engine can feel somewhat strained when pushed hard, and the automatic transmission sometimes hesitates during downshifts. The gear ratios are optimized for fuel economy, resulting in a relatively relaxed driving experience. Compared to a manual transmission equipped Trax, the automatic version sacrifices some responsiveness and driver engagement. Higher trim levels with more powerful engine options (not available in the US market) offered significantly improved acceleration and overall driving dynamics.
Equipment & Trim Levels
The 1.4L Automatic Trax typically came standard with features such as air conditioning, a basic infotainment system with a touchscreen display, Bluetooth connectivity, and power windows and locks. Safety features included anti-lock brakes (ABS), stability control, and multiple airbags. Higher trim levels added features like a rearview camera, upgraded infotainment systems with Apple CarPlay and Android Auto compatibility, heated front seats, and a sunroof. Interior upholstery was typically cloth, with optional leather available on higher trims. Dashboard configuration was relatively simple and functional, prioritizing practicality over luxury.
Chassis & Braking
The Trax I utilizes a front-wheel-drive platform with a MacPherson strut front suspension and a torsion beam rear suspension. This setup provides a comfortable ride quality, but handling is not particularly sharp. The front brakes are ventilated discs, while the rear brakes are drums. This configuration was common for vehicles in this weight class and price range. Electric power steering provides light and easy steering effort, making it well-suited for urban driving. Stabilizer bars were included on both axles to reduce body roll during cornering, though their effectiveness was limited by the torsion beam rear suspension.
Market Reception & Comparison
The Chevrolet Trax 1.4L Automatic was generally well-received as an affordable and practical subcompact SUV. Critics praised its spacious interior, comfortable ride, and fuel efficiency. However, some reviewers noted its lackluster acceleration and somewhat basic interior materials. Compared to competitors like the Honda HR-V and Mazda CX-3, the Trax offered a lower price point but lacked the same level of refinement and driving enjoyment. Fuel economy was competitive, averaging around 28 US mpg in combined driving. Reliability was generally considered average, with some reports of minor issues with the turbocharger and automatic transmission.
Legacy
The 2017-2022 Chevrolet Trax I 1.4L Automatic has become a common sight on the used car market. The LUW engine, while generally reliable, requires regular maintenance, including oil changes and spark plug replacements. The six-speed automatic transmission is also relatively durable, but may require fluid changes and occasional servicing. The Trax remains a popular choice for budget-conscious buyers seeking a versatile and practical subcompact SUV. Its affordability and relatively low running costs make it an attractive option for first-time car owners and those looking for a dependable daily driver. However, potential buyers should be aware of the engine’s potential for turbocharger issues and the transmission’s occasional hesitation.
