Powertrain & Engine Architecture
The Roewe D5X DMH 1.5T utilizes a sophisticated plug-in hybrid powertrain. The core of the system is a 1.5-liter turbocharged four-cylinder engine (code 15FKE) producing 150 horsepower and 235 Nm (173.33 lb.-ft.) of torque. This engine employs direct fuel injection and a double overhead camshaft (DOHC) valvetrain for optimized combustion efficiency. Complementing the internal combustion engine is a 197 horsepower electric motor integrated with a dedicated hybrid transmission (DHT – Dedicated Hybrid Transmission). This DHT system, a key technology for SAIC, allows for seamless switching between electric, hybrid, and gasoline power modes. The 21.4 kWh lithium iron phosphate (LiFePO4) battery pack, positioned under the vehicle floor, provides an all-electric range of 105-135 km (65.24 – 83.89 mi). The combined system output reaches a substantial 347 horsepower.
Driving Characteristics
The D5X DMH 1.5T offers a refined driving experience. In pure electric mode, it delivers near-silent acceleration and is well-suited for urban commuting. The DHT transmission, with its two fixed gear ratios, prioritizes efficiency and smooth power delivery. While not geared for outright performance like some sports SUVs, the combined output of 347 hp allows for a 0-100 km/h (0-62 mph) time of 6.9 seconds. The electric motor provides instant torque, enhancing responsiveness, particularly at lower speeds. Compared to lower-powered D5X variants, the DMH offers significantly improved acceleration and overall performance. The hybrid system intelligently manages power distribution, optimizing fuel economy during longer journeys.
Equipment & Trim Levels
Specific trim levels and standard equipment for the D5X DMH 1.5T can vary depending on the market. However, it generally includes features such as a large touchscreen infotainment system, digital instrument cluster, leather upholstery, automatic climate control, and a suite of advanced driver-assistance systems (ADAS). These ADAS features typically include adaptive cruise control, lane keeping assist, automatic emergency braking, and blind-spot monitoring. Optional extras may include a panoramic sunroof, premium audio system, and ventilated front seats. The interior design emphasizes a modern aesthetic with high-quality materials and a focus on passenger comfort.
Chassis & Braking
The D5X DMH 1.5T features a front-wheel-drive layout. The suspension system consists of independent McPherson struts at the front and an independent multi-link setup at the rear, providing a balance between ride comfort and handling stability. Ventilated disc brakes are used on all four wheels, ensuring adequate stopping power. The electric power steering system offers light and precise steering feel. The vehicle’s weight, at 1880 kg (4144.69 lbs), is relatively high due to the battery pack and hybrid components, but the suspension is tuned to mitigate body roll and provide a composed ride.
Market Reception & Comparison
The Roewe D5X DMH 1.5T is primarily targeted at the Chinese market, where demand for plug-in hybrid SUVs is rapidly growing. Initial reviews have praised its fuel efficiency, comfortable ride, and advanced technology. Compared to other D5X variants, the DMH offers a significant performance upgrade and the convenience of all-electric driving. Competitors in the Chinese market include models from BYD, Geely, and other domestic brands, as well as international players like Volkswagen and Toyota. The D5X DMH’s competitive advantage lies in its combination of performance, range, and features at a competitive price point.
Legacy
As a relatively new model, the long-term reliability of the Roewe D5X DMH 1.5T remains to be fully established. However, SAIC Motor has been investing heavily in electric and hybrid technologies, and the LiFePO4 battery chemistry is known for its stability and longevity. The DHT transmission is a key component of SAIC’s hybrid strategy, and its performance and durability will be crucial to the D5X DMH’s success. In the used car market, the D5X DMH is expected to hold its value well due to its advanced technology and fuel-saving capabilities. Its status as a representative of Roewe’s transition towards electrification will likely contribute to its appeal among environmentally conscious buyers.
