On April 26, "Who is the strongest hybrid on the surface?" ——The Japanese Hybrid Technology Challenge was officially held in Guangzhou Lotus Mountain Asia International Yacht City. Professional automotive media from South China gathered at the foot of Lotus Mountain to test the track performance of nissan Xuanyi electric drive version e-POWER, Toyota Corolla dual engine and Honda Enjoy Domain Sharp Hybrid on the Jincana Circuit. Without further ado, let's take a look at who is more favored by these three major hybrid models!
What is the difference between the three hybrids?
Let's first briefly introduce the basic situation of the three unplugged hybrid systems, Toyota THS system is similar to honda i-MMD system, the same is a hybrid hybrid, but the essence of the drive method is different. Among them, the core of Toyota's THS hybrid system is the planetary gear, which adjusts the engine condition through feedback on the battery, power, vehicle condition and throttle, and ensures the best working conditions of the engine at any time with the motor and battery. Honda's i-MMD hybrid system is based on two motors as the core as a variable speed function, which can be responsible for both speed regulation and power output.
Specifically, the motor will be responsible for the main driving work when the Toyota THS system is running at low speed, and the fuel engine will only be responsible for charging the battery; As the speed increases or the deep throttle accelerates, the fuel engine will intervene and drive the vehicle with the generator. The i-MMD system in driving, low-speed driving, the fuel engine drives the generator, responsible for charging the battery, at this time, the only power for the vehicle to move forward comes from the drive motor, stationary start and low-speed power response will be much better than ordinary fuel models; During the medium and high-speed driving process, the E-CVT transmission will change the driving mode of the vehicle, and the fuel engine is responsible for driving the vehicle forward.
As for Nissan's hybrid e-POWER, it is completely different from the route taken by the first two. In the e-POWER system, only the motor is responsible for driving the vehicle, and the fuel engine is only responsible for charging the motor, which is a bit like the way the extender electric system works. The difference is that the fuel engine in the e-POWER system will only charge this when the battery power is less than 60%, and if it is at high speed or rapid acceleration, the fuel engine will also provide power to the drive motor together with the battery pack.
That is to say, the problem of mileage does not need to be overly worried, with the blessing of the fuel engine, the e-POWER system can well avoid the problem of the short mileage of today's pure trams, in addition, the acceleration and power response in the low-speed state will become the highlight of the e-POWER system. It is worth mentioning that in e-POWER technology, it can be stably operated in the most efficient working conditions, thus effectively reducing fuel consumption. And the engine thermal efficiency of the e-POWER system can reach an astonishing 50%, which can be said to be the ceiling of the thermal efficiency of the internal combustion engine.
Each has its own strengths, and the number is seated
The challenge set up a Kinkana circuit that reflects the comprehensive performance of the vehicle in the closed test field, covering test items such as straight line acceleration, pile winding, 8 characters and continuous curves. In the challenge, compared with the two fields that have already formed a strong endorsement, the late e-POWER hybrid system gave a lot of surprises to the media teachers present. In terms of direct acceleration performance, thanks to the characteristics of "full-time electric drive", The e-POWER version of Xuanyi Electric Drive can instantly explode the maximum torque and have a more push back feeling. In terms of corner performance, Xuanyi Electric Drive version of e-POWER showed its "active" side, light steering and solid chassis, showing good cornering performance in the narrow Kinkana circuit.
After the experience of a number of professional media, the fastest lap speed of the three cars on the track was achieved, among them, the fastest lap speed of the Xuanyi Electric Drive version of e-POWER was 38.08 seconds, the fastest lap speed of the Corolla Dual Engine was 38.45 seconds, and the fastest lap speed of the Enjoy Domain Sharp Hybrid was 38.41 seconds. The lap performance difference of the three cars is less than one second, which can be said to have their own strengths, for example, the Xuanyi electric drive version of e-POWER can instantly burst maximum torque, and the acceleration feedback is more pushing back than the other two Japanese hybrids. As for the Corolla double engine, although the acceleration in the front section is not as fast as the other two opponents, due to the blessing of TNGA, the low center of gravity makes it more handy on the curve-complex Kinkana circuit.
Therefore, in general, it is really difficult to distinguish between high and low. It can only be said that different characteristics will serve different consumers, only suitable and inappropriate. If you pay attention to smoothness, comfort, long-distance or high-speed road conditions, more comprehensive, Toyota THS is more skilled; Caring about the driving pleasure level, there are more urban sections, and the Honda i-MMD may be more desirable; For comfort and ultimate fuel savings, nissan e-POWER is better suited to you.
At the same time, from the perspective that the Xuanyi electric drive version of e-POWER can obtain outstanding lap results, Nissan e-POWER Hybrid has enough hard power to become a "spoiler" in the hybrid vehicle market, and together with Toyota and Honda, it constitutes a three-legged situation of Japanese hybrid.
