The range extender is a hybrid electric vehicle, which is characterized by the addition of an internal combustion engine as a generator on the basis of a pure electric vehicle, charging the battery or directly driving the motor, thereby increasing the range and overcoming the range anxiety of a pure electric vehicle. The advantage of the extended-range vehicle is that it can drive a certain mileage with zero fuel consumption and zero emissions, and it does not depend on the distribution of charging piles, so it can replenish energy anytime and anywhere. The disadvantages of range extenders are that they are less efficient in energy conversion, higher fuel consumption at high speeds, and the noise and vibration of the internal combustion engine can affect the driving experience.
Changan Automobile is one of the largest automakers in China and a leader in new energy vehicles. Changan Deep Blue, a new new energy brand under Changan Automobile, launched its first strategic model in 2022 - Deep Blue SL03, which is a medium-sized range-extended electric car that adopts a rear-mounted rear-drive electric vehicle architecture, equipped with a number of industry-leading mass production technologies, and has achieved three major breakthroughs in the fields of intelligence, battery life and electric power. The launch of the Deep Blue SL03 has attracted wide attention and praise, which is considered to be a successful counterattack by Changan Automobile, and also shows the charm and potential of the range extender car.
The exterior design of the dark blue SL03 integrates elements of technology and aesthetics, showing a sense of futurism and sportiness. The body adopts a streamlined fastback shape with a drag coefficient of only 023cd, which is conducive to improving battery life and stability. The front face adopts a closed grille, combined with matrix LED headlights, forming a concise and sharp visual effect. Frameless doors and hidden door handles are used on the sides of the body, which adds to the overall sense of the body and the sense of technology. At the rear, LED taillights are used to create a dynamic and stylish atmosphere, echoing the front face. In terms of body size, the length, width and height of the dark blue SL03 are 4820 1890 1480mm, and the wheelbase is 2900mm, which belongs to the standard of medium-sized cars and has excellent space performance.
The interior design of the dark blue SL03 continues the technological and aesthetic style of the exterior, creating a comfortable and intelligent driving space. The interior features a black and white contrasting design with an enveloping cabin layout that creates a trendy and welcoming atmosphere. The instrument panel adopts an integrated 12The 3-inch LCD screen integrates the instrument panel and the central control screen to achieve multi-functional information display and interaction. The steering wheel has a sporty design with a flat bottom, and the multi-function buttons and paddle shifters provide convenient and flexible handling. The seats are upholstered in leather and electrically adjustable and heated for a comfortable and snug ride. The rear space is excellent, with plenty of legroom and headroom, and a trunk volume of 450 liters, which can meet daily storage needs.
The power system of Deep Blue SL03 is its biggest highlight and advantage, it adopts a hybrid architecture with extended range, which is composed of three powertrains: engine, generator and drive motor. The engine is only responsible for charging the battery or directly driving the generator, while the drive motor is responsible for driving the wheels, enabling a purely electric driving mode. Deep Blue SL03 has launched two models: extended range version and pure electric version, and the extended range version is equipped with 1The 5L Atkinson cycle engine has a maximum engine power of 95 horsepower, a motor maximum power of 160kW, a maximum motor torque of 320Nm, and a battery capacity of 189kWh, the cruising range under comprehensive working conditions is 705km, the pure electric cruising range is 135km, and the fuel consumption per 100km is only 12l。
The all-electric version is equipped with two different battery capacities, which are 515kwh and 705kWh, corresponding to the maximum power of the motor is 135kW and 218kW, the maximum torque of the motor is 280N·m and 335N·m, respectively, and the cruising range under comprehensive working conditions is 515km and 705km respectively. The power system of Deep Blue SL03 can not only provide strong and smooth power output, but also effectively reduce energy consumption and emissions to meet the needs and preferences of different users. The intelligent system of Deep Blue SL03 is also its important feature and advantage, it is equipped with the Deep Blue intelligent system independently developed by Changan Automobile, integrating a number of intelligent functions and services.
Deep Blue Intelligent System adopts artificial intelligence technology, supports voice recognition and interaction, can realize various control and settings of the vehicle, and can also provide navigation, entertainment, information and other content. Deep Blue Intelligent System also supports OTA** upgrade, which can update the software and firmware of the system at any time to keep the system up-to-date. Deep Blue SL03 is also equipped with L3 level automatic driving technology, which supports adaptive cruise, lane keeping, automatic lane change, automatic parking and other functions, which can realize partial control and supervision of the vehicle in scenarios such as highways, and improve the safety and convenience of driving. Deep Blue SL03 also supports intelligent remote control, which can realize the functions of remote start, unlocking, air conditioning control, vehicle condition inquiry and other functions of the vehicle through the mobile phone APP, and can also realize the sharing and leasing of the vehicle to improve the efficiency and value of the vehicle.
The safety system of Deep Blue SL03 is also its features and advantages that cannot be ignored, it adopts a high-strength body structure, and is equipped with a number of active and passive safety equipment and functions. In terms of active safety, Deep Blue SL03 is equipped with a full range of driving assistance systems, including front collision warning, automatic emergency braking, blind spot monitoring, lane departure warning, lane keeping assist, traffic sign recognition, automatic high and low beams and other functions, which can provide effective warning and intervention in different driving scenarios to avoid or reduce the occurrence of accidents. In terms of passive safety, Deep Blue SL03 is equipped with 6 airbags, ABS anti-lock braking system, EBD electronic brake-force distribution system, ESP body stability control system, TCS traction control system, HDC hill descent system and other functions, which can provide maximum protection and assistance in the event of an accident and reduce damage to personnel and vehicles.
Deep Blue SL03 is an important innovation and breakthrough of Changan Automobile in the field of new energy vehicles, which not only demonstrates the technical strength and brand image of Changan Automobile, but also provides a strong demonstration and promotion for the development of range extender vehicles. The appearance, interior, power, intelligence, safety and other aspects of Deep Blue SL03 have reached the leading level in the industry, and even surpassed some traditional luxury brands, providing users with a high-quality and cost-effective choice. The range-extender hybrid architecture of Deep Blue SL03 also provides an effective solution to solve the range anxiety and charging problems of pure electric vehicles, and can also meet the requirements of national energy transition and environmental protection. The launch of Deep Blue SL03 not only made Changan Automobile a successful counterattack in the new energy vehicle market, but also made more users realize the charm and potential of range extenders, and opened a new door for the popularization and development of range extenders.
