What is the approximate level of the engines of the two major brands of Wuling and Baojun?
The engine technology of the two major brands of Wuling and Baojun is supported by General Motors. However, due to the low positioning of the two major brands, they are mainly entry-level scooters. Therefore, the technical support available to GM is limited. Even for the ordinary GM LFV flipper 15E4E, the 1.5T direct injection supercharger must first be supplied to the three major steam brands of Roewe, MG and Maxus, but when it is Wuling Baojun's turn, only LJ0 is left. Multi-point EFI machine.
Baojun RS5: The higher it jumps, the fiercer it jumps. Baojun is not suitable for charging.
The maximum output power of the LJ0-1.5T turbocharger is as low as 108kw, which is only 147 horsepower in meters. . The maximum torque is 250n, which is pretty good, but the efficiency of the supercharger is too low. The maximum torque will not explode before 2200 rpm, and the continuous output range is only 2200~3400 rpm. On the other hand, most engines of this displacement installed in this car are low-inertia and high-efficiency superchargers. It is expected that the continuous output range of peak torque is between 1500 and 4000 rpm. The output of the LJ0 engine in the high and low speed range is average. .
The guide price of Baojun RS5 is 97,800 to 135,800, and the price of the automatic version has reached 107,800. In this range, it is impossible to find the same type of backward machine from the first-tier domestic cars. The focus of this engine is also used in Wuling Hongguang S3 and PLUS vans, which shows how low the core technology level of RS5 is. This is a so-called "independent joint venture" that has no core technology and relies on foreign companies to eliminate models. As a joint venture, foreign companies have the right to speak. What can it do?
The transmission level of the Baojun RS5 is also low enough. The price of the 6-speed manual version overlaps with competing products equipped with direct injection superchargers and wet dual clutches, so the MT-RS5 can be eliminated directly. The remaining CVT automatic version is definitely not an ideal choice. Since the level of the transmission is very low, the special bevel gear steel belt shifting structure relies on sliding friction transmission, resulting in large power losses and wear problems in normal use. Due to the poor fluidity of the transmission oil in low-temperature cold-start vehicles, the bevel gear steel belt must be fully lubricated to delay wear. Therefore, after a cold start, the vehicle must be upgraded to in-situ heating (heating the transmission oil). The user experience can be said to be quite average
Key point: The body structure of Baojun RS5 seems not to be ideal. The proportion of high-strength and ultra-high-strength steel in the vehicle reaches 56%, but the proportion of hot-type steel is only 7%, which is a relatively average level. In addition, SAIC's domestic, joint venture, independent joint venture and other brands seem to have their own definition of steel strength. The yield strength of high-strength steel is only 400 to 500 MPa, but the materials industry considers nearly 700Mpa to be high-strength steel. The strength of the steel is not announced for the RS5. In addition, since there is no indication of what kind of steel is used in which position, this car is not enough to compete with competing products of the same price. The reasonable positioning is a little higher than the 510, and it must be an entry-level agency car to replace the 530.
Wuling’s new 2.0T engine was officially installed on a parked Geographic GX6 a few days ago in order to test its performance. This 1.7-ton MPV is naturally the best test object for Wuling. On the day of the test, the maximum power of the 2.0T engine reached 155 kilowatts and the peak torque reached 350 Nm. This engine is Wuling's first engine to use in-cylinder direct injection technology. For Wuling, this is a technological milestone.
On the other hand, according to the official announcement of Wuling Motors, in addition to this 2.0T engine, Wuling has also developed a 3.0L engine that is currently technologically immature. It is more complicated for this engine to overcome technical difficulties. Because the first-generation engine developed is too large to be installed on a car, performance testing has not yet been carried out. Wuling is also working overtime to develop the second-generation smaller 3.0L engine. If the development is successful, Wuling will have more say in the "technology flow" market.
