1.5T Which is stronger? China, Germany, Japan, South Korea and the United States have no difference on the same stage PK
Looking at the whole domestic automobile market, small-displacement turbocharged engines have become the mainstream. They have excellent fuel economy while ensuring power, so they are increasingly favored by consumers, and the most popular one is the 1.5T engine.
No matter foreign brands or independent brands, a large number of 1.5T engine models are being laid out, and the price covers the range of 100,000 to 500,000. There is no doubt that the quality of engine technology is by no means the only reason that leads to such a big price gap.
Today, we will put together the mainstream 1.5T engines of brands from China, Germany, Japan, South Korea and the United States, not talking about gearbox matching, but only talking about technology and comparison parameters to see which one is better.
First of all, we need to exclude B38K15T0 of BMW i8 to avoid "breaking the bar". This guy’s data of 231 PS/320 N m is really beyond the reach of conventional 1.5T In order to do our best as a landlord, we’d like to invite 1.5T foreign (joint venture) brands.
Bmw B38A15C
Representative model: BMW Brilliance 120i
Although everyone is talking about the color change of "three" nowadays, BMW’s 1.5T three-cylinder B38A15C engine can definitely be called a flaw. B38A15C adopts BMW’s fourth-generation continuously variable valve lift adjustment system, which can make the low-speed torque higher and the high-speed power higher. Bosch’s fifth-generation high-pressure electromagnetic valve injector improves fuel efficiency, and the integrated turbine housing and exhaust manifold make the warm-up faster. In addition, arc spraying technology and balance shaft system are adopted. B38A15C can finally reach the maximum power of 140Ps at 4600rpm, and the maximum torque of 220N·m can be provided at 1480-4200rpm.

Except Dongfeng DFMC15TDR, the final results of other engines are as follows:
It is not difficult to see that many independent brand engines have surpassed foreign (joint venture) brands in terms of parameters. I believe this result will make many friends question, because the actual power experience of most models of independent brands does not match the parameters. To know that the engine is only responsible for providing power, if you want to transmit more power to the tires, you need a "smart" gearbox to match it perfectly.
Nowadays, the progress of engines is an effective proof that independent brands are becoming stronger, and the technical restrictions from abroad are obviously weakening. I hope that independent brands can master more comprehensive technology and truly go abroad as soon as possible.
