This is mainly because: Nissan puts its own propaganda point mainly on comfort. This leads everyone to think of "big sofa", "spacious" and "comfortable" when they mention Nissan cars; As for the engine technology that is very powerful at home, it has not been promoted as the main propaganda point. Under the comfortable aura, there is no sense of existence, and ordinary car owners know little about it.
In fact, Nissan's engine technology is also very strong, no less than Toyota, Honda, Nissan, Mazda and other car companies, but not as vigorously promoted as other car companies. It is a fact that Nissan VQ series engines have been awarded the title of "Top Ten Engines in Ward's World" for 14 years in a row. It was called by the judges: the engine with the smoothest operation and the most carefree power on the earth. This is a height that "two fields and one horse" can't reach.
The biggest feature of Nissan engine is smoothness and silence, which is called "feather-level smoothness". Its dynamic parameters are not necessarily the strongest, but they must be the lowest noise. After testing, the engine noise of vehicles of the same class, such as Sylphy compared with Corolla, Qi Jun compared with CRV and Teana compared with Camry, is obviously lower. At the same time, the ride comfort of the engine is better, and there is no obvious lag and frustration whether it is speeding up or slowing down.
In addition, the fuel economy of Nissan engine is also very good, and the fuel consumption is also lower than that of the same class. For example, the HR 16 engine used in Sylphy is relatively old in technology, but it has good fuel economy. The comprehensive fuel consumption per 100 kilometers is only 4.9 liters, which is not inferior to that of the same class.
More importantly, Nissan's engine has no serious injuries and common faults. Different from other engines, which have difficult faults such as oil emulsification, oil increase and oil combustion, its engine is smooth and quiet. Although it is not very powerful, it is highly reliable.
Others say that Nissan's engine power is average and there is no advanced technology. In fact, this is also a misunderstanding. Even from the engine power parameters alone, Nissan has a high-performance engine. The 3.8-liter V6 twin-turbo engine on Nissan GTR has a maximum power of 600 HP and a maximum torque of 652 Nm, and the acceleration time of 0-96 km/h is only about 3 seconds. Qi Jun's KR 15 engine has only three cylinders, with maximum power 150 kW and maximum torque of 300 Nm. The maximum power 179 kW and maximum torque 37 1Nm of the KR20 engine carried by Teana are all ahead of the same class. More importantly, Nissan engines can release powerful power in the smoothest way, which is difficult for other car companies to do.
Nissan's engine is so powerful because Nissan has some unique technologies. For example, it uses mirror cylinder hole spraying technology and plasma spraying technology to form a 0.2mm thick spray film in the cylinder. The inner wall of the cylinder looks like a mirror, which can reflect people's shadows. With the help of true circle machining technology, the friction between piston and cylinder wall is greatly reduced. There is also a valve drive mechanism. Engineers specially treated the valve top cylinder and added a hard and wear-resistant DLC diamond-like coating on its surface, which not only improved the wear resistance, but also reduced the friction coefficient. There are also advanced technologies such as timing system driven by silent timing chain, stratified combustion, homogeneous combustion and double injection.
As for the VC-TURBO engine promoted by Nissan, it can be called "the turbocharged engine with the strongest technical level in Japan". Its variable compression ratio technology pursued by automobile engineers for many years was successfully developed by Nissan, which can be said to be a technological revolution of fuel engines. In addition, this engine is also equipped with black technologies such as exhaust manifold cylinder head integration technology, Otto/Atkinson double cycle, intake manifold/in-cylinder double injection. This engine was also installed in the new Qi Jun car. As a result, because it was a three-cylinder engine, it was damaged by the domestic media and the sales volume was bleak. In order to save sales, I had to reproduce old Qi Jun. This incident has so far made Chinese people blush.
Nissan Nissan is a great car company in automotive technology! Nissan is the first Japanese company to develop v6 engines, and the first company in the world to own both v6 and straight 6 engines. The world record of 14 consecutive ward prize created by Nissan vq engine has not been solved so far, and the power potential of Nissan GTR engine is almost abnormal. Newbei, the only Japanese company, won the first world lap speed record, and it is also the only company in Japan that accelerated to 3 seconds without adding a motor. The world's three largest cars, McLaren's ancestral v8, Nissan's technology! Nissan is one of the companies with the strongest technical reserves in Japan, with the same number of patents as Toyota. Nissan Gatt is one of the three largest gearbox manufacturers in the world, the largest cvt manufacturer in the world and the record holder of the maximum torque CVT. The newly-added 2t and the 450 Niu Chao torque steel chain CVT on the qx50 in finidi, England are not available in the two fields at present, are they? Nissan epower electric technology ranks among the top in global sales and has top safety. So far, there have been no accidents caused by this system. Note, a Nissan epower hybrid vehicle, has the largest sales volume in Japan and will soon be introduced to China. Black technology, variable compression ratio technology, turbocharged engine with the highest thermal efficiency in the world, revolutionary technology of internal combustion engine.

This is common sense, there is no need to say it. Remember one thing: after buying a car, if you don't want to do too much, you can buy a Japanese car or a Mercedes-Benz BMW.
