Compared with the difficulty and slowness of gasoline-electric hybrid or hydrogen-electric technology, extended-range hybrid technology shows the advantages of ease and speed. Because of this, new power brands such as Lideal and Wenjie have also chosen to take "shortcuts" and have achieved good market results. As a result, some car companies have also begun to research extended-range electric vehicles. In the field of cars, Changan Deep Blue SL03 is currently very popular. Today, we also found a Changan Deep Blue SL03 extended-range version. Next, let’s take a look and see how it performs:
The guide price of the Changan Deep Blue SL03 is 168,900, which is a relatively low price threshold among new energy mid-size cars. Of course, this is one of the reasons why it has attracted everyone’s attention. It is worth mentioning that, unlike those oil-to-electric models, Changan Deep Blue SL03 is based on Changan 's new EPA1 pure electric platform. It is also the first model on this platform. Therefore, if you want to understand Changan's vehicle manufacturing capabilities in the new energy field, you can also find some answers from Changan Deep Blue SL03.
Like most new power sedans, the appearance design of Changan Dark Blue SL03 is quite individual. The overall design is quite fashionable and sporty, especially the angular appearance does bring good recognition. The front of the car has a common closed design, the headlights are quite majestic, and it is equipped with a matrix light group that supports interactive light language, which looks very technological.
Changan Dark Blue SL03's body side shows a sense of weight, and the front of the car has a relatively low posture. The fastback body is paired with frameless doors, hidden door handles and other designs, which further enhances the smoothness and fashion of the side. As for the body size, the length, width and height of Changan Dark Blue reach 4820x1890x1480mm, and the wheelbase is 2900mm.
The design of the rear of the car is also avant-garde. The through-type taillights and tail wings adopt an integrated design, and the outline of the rear surround also echoes the taillights, giving the whole a good sense of hierarchy. It is worth mentioning that the tailgate of Changan Dark Blue SL03 adopts a hatchback design, which is quite innovative among models of the same level.
Sitting in the car, Changan Deep Blue SL03 adopts a minimalist design like most new models on the market. Even its air-conditioning outlet is hidden in the center console. The steering wheel has a rare double-spoke design and is wrapped in leather. Underneath is a floating full LCD instrument panel with a size of 12.3 inches. The central control screen is a relatively conventional floating design with a size of 14.6 inches. However, what is unique about it is that this central control screen can be deflected 15 degrees toward the main driver and co-pilot respectively, which brings a certain sense of ritual. At the same time, it is more convenient for the main and co-pilot passengers to grasp vehicle information and control. This design is relatively rare.
As for the car machine, its operating system is supported by the currently more mainstream Qualcomm 8155 car-grade chip. This car machine chip is also currently used in brands such as Xpeng, Weilai, jikrypton, etc., so the response speed of the entire system is relatively fast. Functionally, Bilibili, Changba , navigation, voice interaction, etc. are also equipped, which are relatively convenient to use in practice.
In terms of intelligent driving assistance, this part is not the strong point of Changan Deep Blue SL03. In terms of hardware, it is equipped with 5 exterior cameras, 1 interior camera, 6 ultrasonic radars and 3 millimeter wave radars . In terms of software, the car is equipped with relatively common active braking, full-speed adaptive cruise, road traffic sign recognition, merging assist, lane centering, etc., and the assisted driving level has reached L2 level. As for the relatively high-end automatic lane change assist, automatic ramp exit (entry) and automatic parking functions, Changan Deep Blue SL03 is not equipped and does not support optional equipment.
The wrapping of the seat is quite good, and the wing support and head support are in place. Functionally, both the main and passenger seats support electric adjustment, but unfortunately, the lumbar adjustment is only supported by the main driver's seat and not the passenger's seat. In terms of other functions, the front seats also support heating and ventilation functions, and the main driver's seat also has a memory function. Overall, the performance is not bad.
Thanks to its good body size, and because it comes from a pure electric platform, the rear floor of Changan Deep Blue SL03 is also flat, so its overall seating space is relatively spacious. What is worth mentioning is its trunk, hatchback opening method, coupled with the configuration of the electric tailgate and electric tailgate position memory function, so its practicality is quite good. The official has not announced its cargo capacity, but its regularity is still quite good.
After reading the performance of Changan Deep Blue SL03 in the above parts, let’s focus on its power system. From the perspective of the power system composition, Changan Deep Blue SL03 extended range version has the same principles as the extended range technology used by Ideal Auto and Wenjie Auto, and there is no difference between them. However, there are differences between them. Changan Deep Blue SL03 Extended Range Edition uses Force Range Extender Technology, which is also the first model equipped with this technology. This technology mainly uses a high-efficiency all-round range extender, non-inductive NVH technology and smart energy management strategies, which can greatly improve efficiency and improve the difficulty of driving in winter.
The entire power system consists of a range extender, a drive motor, and a large-capacity battery. The range extender, which is what we often call the engine, is the 1.5L naturally aspirated engine code-named JL473QJ. This engine has a maximum power of 70kW, which is not outstanding among engines of the same displacement, but it does not participate in driving. Regarding the efficiency of this engine, the data given by the manufacturer is that 1L of fuel can generate 3.3kWh of electricity. Its feed fuel consumption is 4.5L/100km, which does have certain advantages compared to ordinary 1.5L engines.
In terms of drive motor, Changan Deep Blue SL03 is equipped with a rear permanent magnet/ synchronous motor with a maximum power of 160kW and a maximum torque of 320N·m. The transmission system is an ordinary electric vehicle single-speed gearbox. Driven by this electric motor, Changan Deep Blue SL03 accelerates from 0-100km/h in 7.5 seconds, while the vehicle's power consumption per 100 kilometers is 13.1kWh/100km.
As for the battery, Changan Deep Blue SL03 is equipped with lithium iron phosphate batteries from CATL or Sino-Sino Aviation. The battery capacity is 28.39kWh. The pure electric cruising range (CLTC) that this battery pack can achieve is 200km. At the same time, the car supports fast charging, and the fast charging time is 0.5 hours. Unfortunately, the fast charging interface requires 2,000 yuan to be installed. With the cooperation of the 1.5L range extender and battery pack, the Changan Deep Blue SL03 has a comprehensive operating range of up to 1,200 kilometers, and the data is still quite attractive. In addition, it is worth mentioning that the battery of Changan Deep Blue SL03 also uses micro-core high-frequency pulse heating technology. Even in a low temperature environment of -30°C, the battery can be heated extremely quickly, improving the vehicle's power performance by 50% and shortening the charging time by 15%, improving the difficulty of using the car in winter.
Summary:
In the current situation where charging piles are not particularly abundant, we have to admit that the extended-range electric vehicle still has obvious advantages over pure electric models. Especially when traveling far away, the lack of battery life anxiety is even more valuable. At the same time, compared with traditional fuel-powered cars, extended-range electric vehicles like the Changan Deep Blue SL03 can be green-labeled and have the driving experience of a pure electric vehicle. In other words, in the process of transitioning from traditional fuel vehicles to electric vehicles, it is not unreasonable for extended-range electric vehicles to be popular. If your budget happens to be 170,000 to 80,000 yuan, I would personally recommend an extended-range electric vehicle like the Changan Deep Blue SL03.
