INTRODUCTION
The Hyundai Tucson III facelift, launched in 2018, represented a mid-cycle refresh for the popular compact SUV. The 1.6 CRDi 136 hp Mild Hybrid variant, introduced in 2019, was a key component of Hyundai’s strategy to improve fuel efficiency and reduce emissions across its range. Utilizing a 48V mild-hybrid system, this version aimed to provide a balance between performance and economy. It sat in the middle of the Tucson III lineup, offering a more affordable alternative to the more powerful diesel and gasoline engines, as well as the later full hybrid options. This model was primarily sold in the European market, where diesel engines remained popular due to their fuel efficiency and suitability for long-distance driving.
Powertrain & Engine Architecture
At the heart of this Tucson variant lies Hyundai’s Smartstream 1.6-liter four-cylinder diesel engine, designated the D4FE. This engine produces 136 horsepower at 4,000 rpm and 320 Nm (236 lb-ft) of torque between 2,000 and 2,250 rpm. The engine features a turbocharger with an intercooler, direct fuel injection using a common rail system, and a double overhead camshaft (DOHC) valvetrain. The key differentiating factor is the 48V mild-hybrid system. This system incorporates a 48V lithium-ion battery and a belt-driven starter generator (BSG). The BSG allows for regenerative braking, capturing energy during deceleration and storing it in the battery. This stored energy can then assist the engine during acceleration, reducing load and improving fuel economy. The engine also incorporates a start-stop system to further enhance efficiency. The transmission is a 6-speed manual gearbox, chosen for its efficiency and driver engagement.
Driving Characteristics
The 1.6 CRDi 136 hp Mild Hybrid Tucson offers a comfortable and refined driving experience. While not particularly sporty, the engine provides adequate power for everyday driving situations. Acceleration from 0-60 mph takes around 10.6 seconds, and the top speed is 111.85 mph. The mild-hybrid system provides a subtle boost during acceleration, making the engine feel more responsive. The 6-speed manual transmission is well-matched to the engine, offering smooth gear changes. Compared to the more powerful 2.0-liter diesel variants, this version feels less urgent, but it compensates with improved fuel economy. The manual gearbox provides more driver control than the optional automatic transmission available on other Tucson trims. The suspension is tuned for comfort, absorbing bumps and imperfections in the road well.
Equipment & Trim Levels
The 1.6 CRDi Mild Hybrid Tucson typically came with a good level of standard equipment. This included air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, Bluetooth connectivity, and a suite of safety features such as ABS, ESC, and multiple airbags. Higher trim levels added features like leather upholstery, heated seats, a panoramic sunroof, and advanced driver-assistance systems such as lane departure warning and automatic emergency braking. Interior upholstery was typically cloth on base models, with leather options available on higher trims. Dashboard configuration was consistent across the range, featuring a modern and user-friendly design.
Chassis & Braking
The Tucson III utilizes a front-wheel-drive platform with independent suspension on all four wheels. The front suspension employs a McPherson strut setup with a coil spring and anti-roll bar, while the rear features a multi-link suspension system, also with a stabilizer bar. This configuration provides a good balance between ride comfort and handling. Braking duties are handled by ventilated discs on the front wheels and solid discs on the rear. ABS (Anti-lock Braking System) is standard, ensuring safe and controlled braking in various conditions. The chassis is designed to provide stability and predictability, making the Tucson easy to drive and control.
Market Reception & Comparison
The 1.6 CRDi Mild Hybrid Tucson was generally well-received by critics, who praised its fuel efficiency and comfortable ride. It was seen as a sensible and practical choice for buyers seeking a compact SUV with low running costs. Compared to the higher-output diesel variants, it offered similar practicality but with lower fuel consumption and emissions. However, some reviewers noted that the engine could feel underpowered when fully loaded or driving uphill. Against competitors like the Nissan Qashqai and Kia Sportage, the Tucson offered a competitive package with a strong warranty and a well-equipped interior. Fuel economy figures of 5.8-6 l/100 km (40.6-39.2 US mpg) were a key selling point.
Legacy
The 1.6 CRDi Mild Hybrid Tucson represents an important step in Hyundai’s transition towards electrified powertrains. While not a groundbreaking vehicle, it demonstrated the potential of mild-hybrid technology to improve fuel efficiency and reduce emissions. In the used car market, these models are generally considered reliable and offer good value for money. The Smartstream engine has proven to be durable, and the mild-hybrid system has not been associated with any major issues. However, as with any diesel vehicle, it’s important to ensure that the AdBlue system is functioning correctly and that the vehicle has been properly maintained. The Tucson III, in general, has established a reputation for reliability and practicality, making it a popular choice among used car buyers.
