The Infiniti QX30 2.2d AWD DCT, launched in 2016, represents a unique offering within the compact luxury crossover segment. Built upon the Mercedes-Benz GLA platform – a result of the Daimler-Renault-Nissan alliance – the QX30 aimed to bring Infiniti’s signature style and a degree of practicality to a market dominated by European competitors. This particular variant, powered by a 2.2-liter turbocharged diesel engine producing 170 horsepower and paired with a seven-speed dual-clutch transmission (DCT) and all-wheel drive, occupied a middle ground in the QX30 lineup, balancing fuel efficiency with respectable performance. It was primarily marketed towards buyers seeking a premium crossover with a more economical engine option than the gasoline-powered alternatives.

Powertrain & Engine Architecture
The heart of the QX30 2.2d is the OM651.930, a 2.143-liter inline-four cylinder diesel engine developed by Mercedes-Benz. This engine is a member of the OM651 family, known for its robust construction and efficiency. It features a common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A turbocharger with an intercooler further enhances performance, providing increased air intake to the engine. The engine produces 170 horsepower at 3400-4000 rpm and a substantial 350 Nm (258 lb-ft) of torque between 1400-3400 rpm. This broad torque curve is a key characteristic of the engine, providing strong pulling power at lower engine speeds. The engine is transversely mounted in the front of the vehicle. The seven-speed dual-clutch transmission (DCT) provides quick and smooth gear changes, contributing to a more engaging driving experience compared to a traditional automatic.
Driving Characteristics
The QX30 2.2d AWD DCT offers a comfortable and refined driving experience. The diesel engine’s ample torque makes everyday driving effortless, with brisk acceleration from a standstill and confident overtaking capabilities. While not a sports car, the 8.5-second 0-60 mph acceleration time is respectable for a compact crossover. The DCT transmission contributes to a responsive feel, although some drivers may notice slight hesitation at low speeds. The all-wheel-drive system provides enhanced traction and stability, particularly in inclement weather conditions. Compared to the gasoline-powered QX30 variants, the 2.2d prioritizes fuel economy over outright performance. The manual transmission versions of the 2.2d offered a slightly more engaging driving experience, but the DCT provides convenience and ease of use.
Equipment & Trim Levels
The QX30 2.2d AWD DCT typically came well-equipped, reflecting its luxury crossover positioning. Standard features often included leatherette upholstery, a 7-inch touchscreen infotainment system with navigation, rearview camera, automatic climate control, and a suite of safety features like automatic emergency braking and lane departure warning. Optional extras included genuine leather upholstery, a panoramic sunroof, premium audio system, and adaptive cruise control. Trim levels varied by market, but generally offered increasing levels of luxury and technology. The 2.2d trim often sat in the mid-range of the QX30 lineup, offering a balance of features and value.
Chassis & Braking
The QX30’s chassis is based on the Mercedes-Benz GLA platform, featuring a McPherson strut front suspension and a multi-link rear suspension. This setup provides a comfortable ride quality while maintaining good handling characteristics. The all-wheel-drive system utilizes a multi-plate clutch to distribute torque between the front and rear axles as needed. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic stability control are standard features, enhancing safety and control.
Market Reception & Comparison
The Infiniti QX30 2.2d AWD DCT received mixed reviews from automotive critics. While praised for its stylish design, comfortable interior, and fuel efficiency, some reviewers found the diesel engine to be somewhat noisy and the overall driving experience less engaging than some of its European rivals. Fuel economy was a strong point, with combined figures around 48 US mpg. Compared to the gasoline-powered QX30, the 2.2d offered significantly better fuel economy, making it a more practical choice for drivers covering long distances. However, the gasoline engines provided quicker acceleration and a more refined engine note.
Legacy
The OM651 diesel engine used in the QX30 2.2d is known for its durability and reliability, provided it is properly maintained. The seven-speed DCT transmission is also generally considered to be reliable, although regular fluid changes are essential. On the used car market, the QX30 2.2d AWD DCT represents a relatively affordable entry point into the luxury crossover segment. Its fuel efficiency and all-wheel-drive capability make it a practical choice for buyers seeking a versatile and comfortable vehicle. However, potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly if the vehicle has been primarily used for short trips.
