Nissan Serena e-Power test drive in Hiroshima, really low energy consumption?

Nissan launched e-Power technology in 2016, which is different from the pure electric drive of its Leaf. This e-Power power system is also driven by a motor, but the battery The source of electrical energy is generated by the gasoline engine. To put it simply, the gasoline engine only serves as a power generation function, which is similar to the program extension system on the market; Important products indispensable for major brands.

Come and rent an e-Power in Japan and find out!

In order to find out, the test team planned to preemptively go to Japan for a test drive experience, coupled with the counterparts of the Life Channel, after several discussions, finalized the plan and went directly to Hiroshima, Japan for a self-driving journey of “wine making visits”. The place where the brewery is visited is relatively far away. Through the long mileage test drive, direct field test, what kind of performance of e-Power in “fuel consumption”!

Considering that e-Power has a great opportunity to be introduced into the domestic market, the test unit is the first to go to Japan for a test drive. Currently, there are two options under the Nissan: Note e-Power and Serena e-Power.

A total of 4 members traveled to Hiroshima for a wine brewing self-driving tour, plus photographic equipment, large luggage, etc., so deliberately rented a 7-seat Nissan Serena e-Power set up, at least for a journey of nearly 400 kilometers , The crew can enjoy driving time comfortably.

Although the main goal of this test trip to Hiroshima, Japan is the e-Power powertrain experience, here we will introduce the 7-seater mid-size MPV-Serena. The test drive of this Serena e-Power was a real “new car”. When it was picked up from the car rental company, it was found that its total mileage was less than 100 kilometers.

What is the difference in e-Power's visual performance

The reason why it is so new is that this is a version that belongs to the 5th generation minor modification. The Japanese market was officially released in early August 2019. The small modified Serena front water tank cover is paired with silver dots. The V-shaped chrome trim strips extend to both sides and separate the headlight group into two layers. Under this design called V-motion by the factory, the air dam has an X-like shape, and Give the front styling a rather obvious three-dimensional feel.

The combination of chrome trim and silver dot V shape is exclusive to the Serena top model Highway Star, while the e-Power version of the Serena Highway Star model is inside the V chrome trim, plus a blue Trim strips (non-Highway models also have exclusive blue trim strips), revealing that they are not traditional gasoline-diesel fuel-driven models, with the side of the car at the lower edge of the front door and the rear right rear of the car. The distinctive design of the characters, especially the white characters on a blue background, is proof of their different power configurations.

The Japanese-style Serena has launched a variety of models and power options. The e-Power models will have a blue stripe at the front water tank cover to show their power. The large V-shaped water tank cover in the picture is the top Standard Highway Star models.

At the lower edge of the front door panel, and at the right rear of the rear, there are e-Power nameplates, and the e letter is especially presented in white on a blue background.

The large and medium-sized Nissan Serena e-Power has a very spacious cabin. The sizes are 4,770 mm in length, 1,740 mm in width, and 1,865 mm in height. The wheelbase is 2,860 mm. , This size with 2 + 2 + 3 seat configuration, so that the second row is like business class. Many thoughtful and convenient designs provide a comfortable and convenient personal space, including retractable small table boards behind the first and second rows of chairs, USB charging holes, and small hooks for storage. The door also adopts double-sided electric side sliding doors for convenience and has an inductive opening function.

Serena’s cabin space is quite outstanding. With a body wheelbase of 2,860 mm and a seat configuration of 2 + 2 + 3 (top gauge model), the rear passengers have a very good sense of comfortable space.

The third row of seats is not designed to be flat and folded, but can be stored on both sides. Although it can also create flexible use of space, it will always have some impact compared to the flat design.

The design section of the front cockpit uses a multi-layer stacking method. The slender instrument extends all the way to the front of the center console. The digital information display at the middle sample position can switch many information contents. In addition to the data, when ProPilot is started, it will also display information content including distance, left and right lane markings, ACC speed setting, etc. According to the original factory information, this information screen can also display images of power transmission, but because of personal I’m sorry in Japanese, so the display could not be found.

The layout of the cockpit is actually quite easy to read information. It adopts a multi-level design that takes into consideration the use of space and various operations.

In the part of the central touch screen that supports audio and video entertainment, because the car rental company does not adopt a large-sized central control screen configuration, it does not support Apple CarPlay or Android Auto smart mobile devices in series; another interesting design There is a storage box between the multi-function steering wheel and the instrument. There is also a USB jack inside, which is considered as a driver-only design. However, there is no USB jack found on the side of the front passenger seat. It is a general 12V charging hole.

Convenient for convenience, including up to 6 USB jacks in the whole car, folding table and cup holder on the back, etc. Even the third row occupants enjoy independent cup holders and USB .

Although it has an engine, it is driven by an electric motor

At the lower edge of the center console is the gearshift seat, engine start button, electronic handbrake and Auto Hold start button. From the configuration of the gearshift system, we can clearly understand that this Serena e-Power is an “electric “Because in addition to the D gear, there is also a common B gear on electric cars. Some people may say that the B gear is not necessarily proof of the electric car model, but after pressing the blue engine start button, , The vehicle started silently, this is indeed an “electric” car.

The blue engine start button and the D / B gear display on the gearshift system reveal that this is an electric-related product.

Serena e-Power is a purely electric car driven by a motor. There are two power sources for the motor. One is powered by a 1.8 kWh lithium battery, and the other is powered by a gasoline engine. Power transmission.

The configuration of the engine room seems to be more similar to models such as Hybrid or Plug-In Hybrid. However, e-Power is different from the general gasoline-electric hybrid design.

When Nissan announced the e-Power technology, he also announced a power architecture diagram. The gasoline engine is connected in series with the generator, and then the lithium battery is directly charged. There is an inverter configuration between the lithium battery and the drive motor. It is not difficult to understand clearly that the gasoline engine is actually the concept of a “generator”, and the entire structure is similar to a range-extended electric vehicle. Because the battery has only half the power left when the car is picked up, shortly after stepping on the accelerator pedal and driving the taxi center quietly, connecting the highway section from the ramp, deepening the accelerator pedal on the foot, I heard the gasoline engine started move. Theoretically speaking, with the current e-Power power system configuration and 1.8 kWh lithium battery capacity, if it is Mercedes-Benz on a level road in Mercedes-Benz, Serena e-Power’s engine will need to be turned on every few kilometers for battery operation. Charging, but through the design of recharging, and because of different application environment, the battery usage will naturally be different.

In different driving environments and situations, the system’s operating methods are also very different. The most important thing for electric vehicles is how to effectively use every resource. Therefore, when decelerating or downhill, energy recovery will be performed.

Unlike the sound of engine operation of traditional gasoline vehicles, the engine operation of Serena e-Power has no obvious “sound”. It is as if the engine is pulled to a high speed to run and it is maintained at this speed. The depth of the accelerator pedal at that time is not directly related to the engine operation, and it is quite obvious compared to the traditional fuel car models. As the battery becomes full, the sound of the engine disappears. Occasionally, the engine will start again when the foot is at a high speed. At a constant speed cruising speed of about 90 kilometers per hour and coupled with many downhill sections, Serena e- Power not only runs quite quietly along the way, the fuel mileage displayed by the travel computer continues to increase, even once giving people the illusion that the more you earn, the more you earn.

Continued high speed, 1.8 kWh lithium battery seems a bit insufficient

According to the original data, the Serena e-Power’s engine is a 1.2-liter inline 3-cylinder gasoline engine, but its displacement is not related to vehicle performance. The smooth and smooth operation is the focus, but it may be quite new. A car is also likely a Nissan 3-cylinder engine code-named HR12DE. It does have excellent smoothness. The entire test drive process of Serena e-Power has a good smoothness, and the interior of the car is also excellent in most cases. Quietness.

The gauge of Serena e-Power does not display the engine speed, but mainly uses the kinetic energy output as well as the estimated mileage that can be driven. Because the engine will charge the battery, the amount of battery in the lower left corner , And often has an absolute relationship with the quietness of the cabin.

The EM57 DC motor that is really responsible for driving the vehicle. The original power data is a maximum horsepower of 97 kw (about 136 ps) and a maximum torque of 32.6 kgm. The biggest difference between an electric motor and a gasoline engine is that there is no need to wait. The output of the engine speed is sweet, so as soon as you press the accelerator pedal, Serena starts driving directly. In the state powered by lithium battery, the interior of the car is actually quite quiet, even if the engine is occasionally charged to charge the car. The quietness is also pretty good. However, at a speed of more than 100 kilometers per hour, the story is not so simple!

Due to the arrangement of the itinerary (the schedule set by a colleague to visit Jizo), a group of people drove to Jishu, far from Sakai, Yamaguchi, Japan. The one-way distance was more than 150 kilometers, that is, the distance of more than 300 kilometers. It can be used as a stage for comprehensive fuel consumption testing; while driving on high-speed roads, it will be found that e-Power has excellent performance under the driving speed of 80 to 90 hours per hour, but when the current speed exceeds 100 kilometers, the battery consumption is It can be described by haste. From the display on the meter, it can be seen that the power will soon reach the bottom, and the engine is actively running at this time.

Serena e-Power provides three driving modes: Smart, Eco and Normal. In Eco mode, it will have obvious kinetic energy recovery effect, which is the function of the original e-Pedal.

At a high speed and facing the dilemma of battery exhaustion, the engine as a generator naturally has its responsibilities. It is very active and can even make people feel violent operation. At this time, the engine generator not only needs to charge the battery, but also synchronizes it. The electric power is directly supplied to the drive motor for use. Therefore, in addition to the sound transmitted from the chassis when traveling at high speed, there are high-frequency sound waves of the engine running at high speed. I don’t know in my mind: “Well, the power combination of Serena e-Power , It should still be more meek and right! “

e-Pedal and ProPilot, very convenient after getting used to

When it comes to the loss of power, you have to mention the driving mode selection that Nissan equipped for Serena e-Power. The Drive Mode button located at the right rear of the steering wheel can be switched to three modes: normal, Smart S and Eco The most significant difference is the Eco mode; in the Eco mode, the response of the accelerator pedal of Serena e-Power is quite interesting. The technology that the factory calls e-Pedal is actually the concept of maximizing the efficiency of the kinetic energy recovery system. When driving When a person releases the accelerator pedal, the deceleration force will be quite obvious, as if the brake is lightly pressed. This system is similar to the Leaf that has been sold in China (Leaf e-Pedal can reach 0.2G when decelerating), and the driver is moving You only need to control the depth of the accelerator pedal. In fact, it provides a considerable degree of convenience for cruising on high-speed roads, and you don’t need to step on the brakes when stopping on uphill sections.

Another convenient driving mode is to press the ProPilot button on the spoke on the right side of the steering wheel. At this time, the system startup instructions and images will appear on the left screen of the dashboard. At this time, you need to press the Set button on the spoke. That is, the “deceleration” key of the acceleration / deceleration button of the constant speed function is activated, and then the speed setting of the ACC is adjusted by the acceleration / deceleration button; for long mileage high-speed driving, the full-speed active vehicle distance control is integrated , Lane maintenance, lane departure warning, blind spot detection, lane change warning and other functions of ProPilot, indeed added convenience and practicality and a certain degree of safety protection.

The ProPilot button on the spoke on the right side of the steering wheel does not turn on directly after pressing it. The driver still needs to press the Set button to officially turn on, and then can adjust the speed and set other functions.

However, what is more puzzling is the setting of the ProPilot system, an advanced set of equipment that provides driving assistance and safety protection. Now that there are shortcut buttons on the steering wheel, I originally thought that after pressing this blue button, I only Just adjust the speed setting. I did n’t expect to press the setting function again. I feel that the blue ProPilot exclusive button has the fun of taking off pants and farting.

Note e-Power and Serena e-Power, the e-Power system, are a combination of 1.2-liter gasoline engine, 1.8 kWh lithium battery, and electric motor.

Nissan will inevitably use this system in the next car series, such as the next-generation X-Trail, Juke, etc. I believe it will be what consumers expect. After all, as mentioned earlier, increasingly stringent environmental regulations, Or like the upcoming CAFE (Annual Sales of New Car Fuel Consumption in China, imitating the Vehicle Average Fuel Economy Standards, Corporate Average Fuel Economy Standards), etc., are the issues facing major brands, but if the current e-Power system uses The system configuration, although it also has 136 horsepower and 32.6 kilograms of torque comparable to a 3.0-liter gasoline engine, seems to be more suitable for the use of the metropolitan area.

The current combination of e-Power systems has certain advantages in terms of performance. According to the original data, Serena e-Power has an average fuel consumption of more than 24 kilometers per liter. However, in actual use, if it is at a high speed Driving down, there is still some distance from the fuel consumption results displayed by the original factory. However, compared to the same class models, e-Power does have certain advantages.

According to the original factory, Nissan Serena e-Power’s fuel consumption performance (after all, it uses gasoline engines as its energy source, so it can still be converted into fuel mileage). It is 24.4 kilometers per liter. This kind of data is actually very good, even in size The smaller Toyota Sienta, equipped with a 1.5-liter naturally aspirated power unit, has the best fuel consumption of 16.4 kilometers per liter. The gap is quite obvious, with the original 55-liter fuel tank capacity.

Nissan released the concept car IMQ at the 2019 Geneva Motor Show. It is equipped with a new generation of e-Power system and uses a combination of 1.5-liter engine and electric motor. However, the original lithium battery capacity has not been officially announced.

However, as mentioned earlier, during this long-mile test drive, the engine is often working hard at high speeds, so the actual fuel consumption of the test unit is actually less than 20 kilometers per liter. The level (the fuel consumption test results will be announced in the film), even though it is still quite good compared to traditional gasoline and diesel models, but it also means that e-Power should have better performance.

Perhaps at the 2019 Geneva Motor Show, the new e-Power system introduced by the original manufacturer on the concept car IMQ, is equipped with a 1.5-liter turbocharged engine, and the electric motor can provide a maximum of 250 kW (about 340 horsepower). Horsepower, and the maximum torque of 71.4 kilograms, the original factory did not announce the capacity of the lithium battery that it is equipped with. If it is equipped with a larger capacity lithium battery pack, it means that the engine has fewer opportunities to operate, and perhaps the fuel consumption will be Even better, but it also means that costs will increase significantly.

And this is even more curious. At what time will Nissan introduce the domestic e-Power system, which car series will it be equipped with, and whether it will introduce a new generation version? Let us wait and see!
