Buying an electric car? Or buy a fuel car? This is a problem that friends who buy a new car or change cars today must face.
The entire automotive industry has accepted the general direction of electrification transformation, and the domestic retail penetration rate of new energy vehicles has exceeded 20% in November, and it is increasing month by month. However, under the current supporting conditions, electric vehicles still have the shortcomings of charging inconvenience and endurance anxiety; for fuel vehicles, oil prices have long exceeded the 7 yuan mark, and the cost of use has been soaring.
So, an eclectic hybrid model or a consumer's choice.
When it comes to hybrid technology, the first thing that comes to mind is the Toyota THS and honda i-MMD, and indeed, in terms of hybrid technology, these two companies were the first to enter the country.
BUT...... Many people don't know that Nissan in the Japanese system also has its own hybrid technology, called e-POWER. In 2016, the Nissan NOTE with the e-POWER power system was launched in Japan, and it also won the 2017-2019 compact model sales championship in the Japanese domestic market.
Nissan is reluctant to equate e-POWER technology with traditional oil-electric hybrid (HEV), they call e-POWER a "never-before fusion power", in fact, compared with Toyota and Honda hybrid technology, the biggest difference between Nissan's e-POWER models is that the vehicle is completely driven by electricity, the engine does not participate in driving the vehicle, just acts as a generator, the vehicle does not need to be charged, can be completely driven as a fuel vehicle. Models equipped with the e-POWER system also have good fuel economy.
Not long ago, The editor of the electric colt just finished the test drive equipped with this technology of the domestic e-POWER Xuanyi (picture | configuration | inquiry), let me combine the test drive, talk about how this technology is?
The engine generates electricity, the electricity drives the car, so the toss is really fuel efficient?
Some friends may first ask: Is it not fragrant for the fuel engine to drive the vehicle directly? Why should there be an extra energy conversion, oil to electricity and then drive the vehicle, is this not a superfluous move? Energy consumption does not rise but falls, which is unscientific!
In fact, as we all know, when the vehicle has just started or traveled at a low speed, the thermal efficiency of the engine is relatively low, the power output is weak, and the fuel consumption is also high; only after the vehicle runs up and the speed increases, the engine will reach the ideal working state, the work efficiency will be improved, and the fuel consumption will also be reduced.
The fuel-saving logic of e-POWER technology is to make the engine only work in the optimal working range, use the most abundant power, the lowest fuel consumption to generate electricity, and then use electricity to drive the vehicle. Nissan has also developed a high-efficiency engine specifically designed for "power generation" for the e-POWER, because only a single operating condition needs to be considered, there is no need to do everything, and the thermal efficiency is 50%, which is much higher than the average of the drive engine. These "strengths and avoid weaknesses" operations are the key to fuel saving in the entire e-POWER system.
Our test drive is e-POWER super intelligent driving Max, the top version, the test drive route includes the city congestion section and the smooth loop, the air conditioning temperature is set to 23 degrees, the air volume is a gear, the car is two adults, running back and forth for nearly 70 kilometers, I am in accordance with my own driving habits casually, the average fuel consumption at the end of the day is 4.9L/100 kilometers, this data is not amazing, but it is also more fuel-efficient, at least not lost to Toyota and Honda.
The most powerful Xuanyi: peak torque 300Nm, 0-50km/h acceleration of 3.8 seconds
Nissan's e-POWER technology was only introduced in China this year, and it came a little late, and the first model to install this system was the best-selling Dongfeng Nissan Xuanyi. Although the fuel version of Xuanyi has the reputation of high appearance, large space and fuel consumption, there are also people who complain about "power meat", and the blessing of e-POWER technology may change the situation of Xuanyi car system.
As we all know, the biggest feature of electric drive is that the torque output is large and the power response is fast. An electric vehicle of 200,000 or 300,000 can easily crush millions of fuel vehicles with acceleration. Like electric vehicles, e-POWER Xuanyi is 100% electric drive, peak torque of 300Nm, almost twice the fuel version of Xuanyi, this data is also close to the famous Volkswagen EA888 2.0T engine, can be said to be the most powerful Xuanyi.
In the test drive, the power performance of e-POWER Xuanyi was somewhat exaggerated, I did not expect that the 1.2-liter self-priming engine would bring such abundant power, and the official 0-50km/h acceleration performance was 3.8 seconds.
The start at the traffic light is quite powerful, and it directly "jumps" out, not at all like a Xuanyi. I usually drive the Honda CR-V hybrid, and intuitively feel that at the beginning of the acceleration, it is more powerful than the 2.0-liter Honda i-MMD engine.
In addition to electric drive, e-POWER Xuanyi power performance also has two technical details, one is the lithium battery with flash charge flash discharge function, and its technical source comes from Nissan LEAF electric vehicles; and the other is the light body of e-POWER Xuanyi.
The design idea of e-POWER is to do subtraction, remove the complex fuel drive system, do not want large-capacity batteries, light loading, e-POWER Xuanyi's vehicle quality is less than 1 and a half tons. Lightweighting not only improves fuel economy, but also improves the power performance of new cars.
Comfort is not reduced: energy recovery is adjustable, and the large space is still the same
e-POWER Xuanyi is based on the fuel version of Xuanyi upgrade, one of the most concerned issues of users is whether the comfort and functionality of Xuanyi original car have been reduced. Although it is different from the fuel-to-electric vehicle, after all, the powertrain has been changed and a battery is also equipped.
Spare tire under the e-POWER Xuanyi luggage compartment
The first is that the space has hardly changed. E-POWER Xuanyi's battery is placed under the front seat, not the bottom of the luggage compartment, so e-POWER Xuanyi actually has a spare tire! This is rare in hybrid models and may be the only one in its class.
The space in the second row of seats has not changed, and the head and legroom are still generous. Due to the placement of the batteries, the floor under the front seats is no longer flat, and the feet are a bit strange to put up and need to adapt.
Comparison of energy recovery intensity in standard mode and economic mode
Secondly, the energy recovery force is adjustable and the deceleration is gentle. As we all know, electric vehicles have a drag feeling of energy recovery, or can cause discomfort to sensitive passengers, and some people will get motion sickness when riding an electric car.
e-POWER Xuanyi has three driving modes: economic mode, standard mode and sports mode, the economic mode is the most fuel-efficient, but the energy recovery is the largest, there is a clear sense of dragging; replaced by the standard mode drag feeling will be much smaller, from the energy meter can also see that the recovered energy is much smaller, there is no such problem, personally feel that the sports mode in the city is not practical, the standard mode of power commuting is enough.
e-POWER Xuanyi also has a B-stop, which is the mode with the greatest energy recovery, and the vehicle can basically be controlled with a single pedal.
Summary of electric colts
e-POWER Xuanyi is one of dongfeng Nissan's most important products this year, and has been upgraded in power, vehicle and engine, and interior design. The editor of E-POWER Xuanyi believes that the direct competitor of e-POWER Xuanyi is not BYD's Qin DMi, the brand and price are different, and the size of Qin is much smaller. Instead, Toyota's Corolla/Leiling hybrid, and Honda's Lingpai/Xiangyu hybrid, the biggest advantage of e-POWER Xuanyi is power, and the appearance of the car system inheritance is also a selling point.
e-POWER Xuanyi has now opened pre-sale, starting from 138,900 yuan, three models, the top e-POWER super intelligent driving Max to 155,900 yuan, whether it is compared with competitors, or compared with the same level of electric vehicles, this price is not cheap. If you want to use e-POWER Xuanyi impulse, in addition to publicity and promotion, the final pricing should be bolder.
