By 2020, China's new energy vehicle market has flooded into a number of joint venture brand pure electric vehicles. Among them, the Beijing Hyundai festa pure electric vehicle, which was launched in February this year, is the third pure electric vehicle of Hyundai in China. In order to cope with the wave of electrification, GM also sold its assets around the world and concentrated on new energy vehicles. Chevy brand in China's first pure electric vehicle Changxun is late at the beginning of this year. Beijing Hyundai festa pure electric vehicle is built on the basis of the fuel version festa, and its smooth modeling design has been innovated and improved on the basis of following the fuel version. The endurance of nedc490km makes it the leader in the joint venture pure electric vehicle. SAIC general Chevrolet Changxun and Buick micro blue belong to sister models. In order to reduce costs, they have many things in common in vehicle platform, powertrain and intelligent technology. Changxun can also be regarded as the standard replacement product of Buick micro blue. As a joint venture pure electric vehicle within 200000 yuan, what is the product strength of festa pure electric vehicle and Changxun? Which one is more worth buying? [· 1. Range comparison ·] the range of pure electric vehicles is still one of the most important indicators for consumers, so let's first see where their range performance is in the current price range of pure electric vehicles. From the above table, it is not difficult to see that in the price range of 150000-200000, the endurance level of many Chinese brand pure electric vehicles presents a situation of "500 for 600", while the endurance level of joint venture vehicles is generally relatively conservative. However, the 490km endurance capacity of festa pure electric vehicle can be said to be the first echelon of the joint venture pure electric vehicle. As a new vehicle launched in 2020, the 410km endurance capacity of Changxun makes its competitiveness slightly inadequate. [· 2. Comparison of power and battery ·] in terms of power, festa pure electric has a slight advantage, the power of motor is slightly higher, the maximum speed of 165km / h is slightly higher than that of Changxun, and the torque of Changxun 350nm has a slight advantage. Due to no 0-100km / h acceleration results published by both vehicles, the measured result of festar pure electric is 8.37s, and we have not measured the result of Changxun at present. However, considering the power difference and torque difference between the two vehicles, the acceleration ability of Changxun is estimated to be slightly weaker than that of festar pure electric. In terms of batteries, both of them are equipped with ternary lithium batteries. The battery supplier of festa pure electric is Ningde times, and the battery supplier of Changxun is SAIC times, a joint venture company of Ningde times and SAIC Group. Therefore, the battery cell technology level of both companies is similar. The battery aspect mainly depends on how to optimize the battery pack. It can be seen from the two chassis photos and the side photos that the pure electric chassis of festa is more flat, with almost no extra bulge, which greatly reduces the probability of damage to the power battery at the bottom of the bracket. At the same time, in order to load more batteries, it also made a compromise in the form of rear suspension, and changed to a torsion beam instead of a single suspension. On the contrary, although the cross-border vehicle has a higher body, the thicker power battery pack is obviously raised under the chassis. In the same case, the power battery of the cross-border vehicle needs more attention and protection, and there is a slight potential safety hazard. The battery capacity and energy density of festa pure electric are slightly larger, so its endurance is more advantageous. In addition, festa pure electric also has a slight advantage in power consumption. [· 3. Comparison of appearance dimensions ·] in terms of dimensions, festa has advantages in vehicle length and wheelbase, indicating relatively spacious longitudinal space. The location of Changxun crossover vehicle is more advantageous in vehicle width and height, indicating more abundant head space. [· 4. Comparison of interior decoration configuration ·] both of them show obvious brand genes in the aspect of interior decoration. There are different opinions on the design and layout of interior decoration. On the material level, the pure electric fista is relatively more textural, while the "plastic sense" of Changxun interior decoration is relatively stronger. In terms of vehicle and machine, both vehicles support networking applications, and have the function of mobile phone mapping expansion. The practicability and convenience are good in the joint venture pure electric vehicle. In the aspect of vehicle networking, festa pure electric can realize the networking function of a series of trains through the software of BLUElink. It includes the information of vehicle status such as endurance mileage, door opening and closing, etc., and it can also realize the remote control of air conditioning, vehicle locking, charging upper limit and other functions. In addition, the car also integrates Baidu voice assistant. We can control the car's interior components including windows, skylights and air conditioners through voice control. It is worth mentioning that its high accuracy of speech recognition conforms to our daily habits. In addition to the online map, online weather, online music, radio and other software, Changxun's Android system also brings the Internet of vehicles function to Changxun. However, Changxun's advantage configuration is only the Bluetooth key of mobile phone. In addition, there is an Android handsfree phone function that some people think is more advantageous. In terms of vehicle network function, there is no doubt that the pure electric function of festa is more abundant and used. It can monitor information in real time through mobile app and realize a variety of remote control functions. However, Changxun does not conform to its pure electric vehicle identity in terms of the function of the Internet of vehicles. In terms of safety configuration, Changxun is not equipped with adaptive cruise, but only equipped with front collision warning and mitigation system, blind area detection, lane departure alarm. In addition, fista pure electric is also equipped with front car departure reminder, lane keeping assistance system, intelligent adaptive cruise, blind area anti-collision assistance, rear cross anti-collision assistance and other relatively rich auxiliary safety configuration. In contrast, the festa pure electric has L2 level auxiliary driving ability, and has more advantages in safety configuration. [· write at the end] generally speaking, as the first pure electric vehicle launched by Chevrolet in China, Changxun seems to be more like a water test product. It not only does not make a clear distinction with Buick's sister models, but also the whole vehicle does not appear to have obvious highlights in terms of endurance or technology configuration. On the other hand, the fista pure electric vehicle has been fully optimized on the basis of the fuel version. The comfortable and household orientation of the whole vehicle is obvious. The smooth and fashionable shape gives it a higher appearance value than the fuel version. In addition, as a product for the compact home market, festa pure electric also captures the most important endurance capability of these consumers. Compared with the two cars, the author more recommends Beijing Hyundai festa to produce electric.
