INTRODUCTION
The Hyundai Tucson III facelift, launched in 2018, represented a significant refresh of the popular compact SUV. The 1.6 CRDi 136 hp Mild Hybrid AWD variant, introduced in 2019, combined a relatively efficient diesel engine with the benefits of a 48V mild-hybrid system and all-wheel drive. This configuration aimed to appeal to buyers seeking a practical, fuel-conscious, and capable vehicle for various driving conditions. It was positioned as a step up from the base engine options, offering a balance between performance and economy. The facelift brought updated styling, improved technology, and enhanced safety features to the Tucson range.
Powertrain & Engine Architecture
At the heart of this Tucson variant lies the Hyundai-Kia Smartstream 1.6-liter diesel engine, internally designated as the D4FE. This engine utilizes a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine features a turbocharger with an intercooler, boosting power and torque. The 136 hp output is achieved at 4,000 rpm, while the peak torque of 320 Nm (236 lb-ft) is available between 2,000 and 2,250 rpm. The 48V mild-hybrid system incorporates a 16 hp electric motor and a 0.44 kWh lithium-polymer battery located under the trunk floor. This system provides a power assist during acceleration and enables regenerative braking, capturing energy during deceleration to recharge the battery. The transmission is a 6-speed automatic, chosen for its convenience and smooth operation. The automatic transmission is tuned for fuel efficiency, with gear ratios optimized for everyday driving.
Driving Characteristics
The 1.6 CRDi 136 hp Automatic Tucson offers a comfortable and refined driving experience. While not a performance-oriented model, it provides adequate power for most driving situations. Acceleration from 0-60 mph takes around 10.8 seconds, and the top speed is 111.85 mph. The mild-hybrid system provides a noticeable boost during initial acceleration, improving responsiveness. The automatic transmission shifts smoothly, although it can sometimes feel hesitant when downshifting. The all-wheel-drive system provides enhanced traction in slippery conditions, making it a capable vehicle for inclement weather. Compared to the higher-output 2.0-liter diesel variants, this 1.6L engine offers less outright performance, but it compensates with improved fuel economy. Compared to manual transmission versions of the same engine, the automatic provides greater convenience but may slightly reduce fuel efficiency.
Equipment & Trim Levels
The 1.6 CRDi Mild Hybrid AWD Tucson typically came equipped with a generous array of standard features. These included air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, Bluetooth connectivity, and a rearview camera. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Higher trim levels offered additional features such as leather upholstery, heated front seats, a panoramic sunroof, and advanced driver-assistance systems like lane departure warning and automatic emergency braking. Interior upholstery was typically cloth on lower trims, with leather options available on higher-spec models. The dashboard layout was modern and functional, with a focus on user-friendliness.
Chassis & Braking
The Tucson III utilizes an independent suspension setup, with McPherson struts at the front and a multi-link system at the rear. This configuration provides a comfortable ride and good handling characteristics. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, providing enhanced braking performance and stability. The steering is electrically assisted, offering a light and precise feel.
Market Reception & Comparison
The Hyundai Tucson III facelift, including the 1.6 CRDi Mild Hybrid AWD variant, was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and good value for money. The mild-hybrid system was seen as a positive step towards improving fuel efficiency and reducing emissions. Compared to competitors like the Nissan Qashqai and Kia Sportage, the Tucson offered a compelling package of features and performance. Fuel economy was a key selling point, with the 1.6 CRDi achieving around 37.3 US mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the infotainment system.
Legacy
The 1.6 CRDi Mild Hybrid AWD Tucson represents an important step in Hyundai’s development of fuel-efficient and environmentally friendly SUVs. The Smartstream engine and 48V mild-hybrid technology paved the way for future hybrid and electric models. In the used car market, these Tucsons are generally considered to be reliable and well-equipped vehicles. The mild-hybrid system has proven to be durable, and the engine is known for its longevity. 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 journeys. Overall, the 1.6 CRDi Mild Hybrid AWD Tucson remains a popular and practical choice for buyers seeking a versatile and fuel-efficient compact SUV.
