Speaking of independent brand models before, many people will have doubts about their "three major pieces", but in recent years, with the development of independent brand technology, a number of powerful "three major pieces" products have gradually emerged, and Changan Automobile's Blue Whale Engine and Blue Whale Transmission are definitely one of them.
In 2021, Changan Automobile Blue Whale Team debuted in the CTCC China Auto Venue Professional League, with the powerful explosive power of the Blue Whale engine and the exquisite technology of the drivers, the Blue Whale Team made a big splash, not only won the first shot in the history of the NGCC Cup, the first crown in the 1.5T era, and won the fastest lap in many races, the Blue Whale Team driver Wan Jincun also successfully won the CTCC 2021 Season Driver of the Year Championship! In order to let everyone have a more intuitive understanding of Changan Automobile's Blue Whale power, on December 28, Changan's second-generation CS55PLUS model carried out two challenges, let's take a look.
Pulling the tablecloth at an urgent speed, the ornaments do not move like a mountain
The first test was to drive the changan second-generation CS55PLUS to carry out a sharp acceleration of the tablecloth pulling experiment, and the tablecloth was placed with many fragile objects. According to the law of inertia, only the tail speed when the tablecloth is removed is fast enough to ensure that the ornament remains in its original position.
Changan second-generation CS55PLUS is equipped with Blue Whale's new generation NE 1.5T high-pressure direct injection engine, the maximum power has reached a staggering 138kW, the peak torque has reached 300N·m, friends who are slightly familiar with the car should know what such parameters mean for a 1.5T engine. And this blue whale new generation NE 1.5T high-pressure direct injection engine can burst peak torque at 1500 rpm, the daily driving feel is quite brisk, and finally the second generation CS55PLUS successfully completed the tablecloth pulling challenge.
Tow 3 heavy trucks, 90 tons is not a problem
For a car, explosive power alone is not enough, continuous power output is also important, so the second generation CS55PLUS underwent traction testing. The challenge was a heavy-duty truck loaded with 24 new Changan vehicles, with a cumulative total mass of more than 90 tons, while the weight of the second-generation CS55PLUS was only more than 1.4 tons, which seemed like an insurmountable challenge.
However, in addition to the aforementioned Blue Whale new generation NE 1.5T high-pressure direct injection engine, Changan's second-generation CS55PLUS also has an exclusive Blue Whale 7-speed wet dual-clutch transmission. The comprehensive transmission efficiency of the latter is as high as 94.3%, the surging power is non-destructive output, no sense of switching, and the response is fast. Finally, with the blessing of a powerful powertrain, Changan's second-generation CS55PLUS successfully pulled more than 90 tons of vehicles.
1.5T Blue Whale power, technical achievement strength
The reason why Changan's 1.5T Blue Whale Power has such an outstanding performance is inseparable from its core technical strength. Blue Whale's new generation NE 1.5T high-pressure direct injection engine integrates double outlet integrated exhaust manifold, double scroll tube electronically controlled turbocharging, Smart phaser+ external high efficiency water cooling and intercooling, "AGILE Agile" efficient ultra-clean combustion system, intelligent lubrication system, etc., using 350bar high-pressure injection, fully variable displacement oil pump + controllable cooling piston nozzle and other black technologies.
For this Blue Whale 7-speed wet double-clutch transmission, it is jointly built by Chang'an Headquarters and Chang'an British Center, after 8 years of development and verification, it has accumulated more than 100 times of summer, winter, high temperature dry heat, high temperature, humid heat, low temperature, user road durability and other experimental verifications, accumulating more than 10 million kilometers, ensuring reliable product performance. The transmission intelligently lowers the gear according to the degree to which the driver brakes, and uses the lower gear to output more torque when accelerating again, ready to move and wait for the opportunity.
Through this experiment, we can further understand the advanced points of Chang'an 1.5T blue whale power. Blue Whale Power is the first modular power development platform of Chinese brands, filling the gap in the field of domestic automotive platform development, let us look forward to its final market performance.
