Hydrogen fuel is recognized as the cleanest and most environmentally friendly energy source. Hydrogen fuel cell vehicles are also the ultimate energy solution for the automotive industry. Because their power fuel is derived from hydrogen, it emits non-polluting water after combustion, so it does not cause any pollution to the environment. And hydrogenation is as convenient and time-saving as traditional gasoline vehicles, so it has become the ultimate goal of the development of countries and auto companies. Hyundai Motor is at the forefront of the world in the field of hydrogen fuel cell vehicles.
On February 6th, the car headline APP came to South Korea's Yongren speedway as the first test driver, test drive the modern hydrogen fuel cell vehicle NEXO, which will be launched in March this year, to experience the latest technology of Hyundai Motor in the field of hydrogen fuel cell vehicles. .
Hyundai Motor Group, the world's first mass-produced hydrogen fuel cell vehicle, began research and development of fuel cells in 1998. In 2005, it completed the localization of hydrogen fuel cell systems in the country. In February 2013, its first mass production. The Hyundai ix35, a hydrogen fuel cell vehicle, was officially launched at the Ulsan plant in South Korea. Toyota and Honda subsequently launched their own hydrogen fuel cell models. Although the current sales of modern hydrogen fuel cell vehicles in the global market are relatively small, Hyundai Motor seems to be ready to continue to lead the hydrogen fuel cell industry with the NEXO, which is the world leader in terms of cruising range and energy efficiency.
At the explanation meeting before the test drive, Hyundai Motor said that the NEXO hydrogen fuel cell vehicle, which was launched in March, is Hyundai's second-generation hydrogen fuel cell vehicle, and its cruising range can reach 609 kilometers under full power.
At the CES show in 2018, the NEXO hydrogen fuel cell vehicle has been unveiled. As an SUV model, the front grille is decorated with a grille that is different from the traditional style. The horizontal strips are decorated with wavy lines. The headlights are designed with a penetrating design, which Hyundai Motor officially calls the Horizon design. Although the headlights are long and narrow, the headlights are decorated in a small crystal-like style, which is very shiny and fashionable even in the natural state.
The NEXO model is built on a new platform for Hyundai, so it is more spacious in space than the previous generation. The length, width and height are 4670mm, 1860mm and 1630mm, and the wheelbase is 2790mm. As an SUV model, the front and rear rows are very abundant, which can fully meet the comfortable driving needs of most consumers.
The overall body line is rounded, the D-pillar is a hidden design, and the rear headlights are triangular. 5 wheels, the hub is designed in black and silver, and has a small triangle decoration, full of technology. According to Hyundai Motor's official introduction, the shape of the wheel can achieve the best air conditioning flow around the wheel and add a sense of movement.
In addition, there are 17 sets of 19-inch and 19-inch aerodynamic tires for consumers to choose. The body colors are milky white, silver, metallic copper, titanium gray (matt) and dark blue. The titanium-grey body in this test drive looks softer due to the matt effect.
In some small details, NEXO also highlights the future of technology, such as automatic flat door handles (also known as hidden door handles), when the user is close, the door handle will automatically protrude, in the parking state, the door handle is retracted into the body Make the side of the car look cleaner and neat. In addition, the rear window wiper in the rear part is also concealed.
In the interior, the NEXO interior design and workmanship are completely different from the traditional fuel car. The 7-inch LCD instrument panel under the steering wheel and the 12.3-inch LCD central control panel are connected to each other to display real-time data information of the vehicle. The large aluminum alloy trim strips, as well as the centrally arranged silver function button area, the push-button gear design highlights the uniqueness of the NEXO hydrogen fuel car.
The most attractive aspect of the cab is the bridge console. Compared to most conventional models, the NEXO console is slightly higher. The entire console is covered by a silver aluminum panel. All function keys are concentrated on the panel, P and D. The power functions such as R and R are also designed as push buttons. Next to the position of the automatic parking function button and selection knob. The area below the console is the wireless charging area for smartphones, and there is also storage space.
There are two colors of gray and blue monochrome in the interior color. Although they all create a sense of technology that symbolizes the future, different colors can be perceived from the steering wheel to bring different emotions. The gray two-color is more fashionable and simple, which is more in line with the aesthetics of female consumers. The blue monochrome color is relatively deep, so it adds a bit of calmness and low-key, and is also more resistant to dirt.
At the lecture before the test drive, the technician introduced that the power components of the modern hydrogen fuel cell vehicle NEXO are composed of hydrogen storage tanks, electric motors, fuel cells, and high-voltage batteries. The starting principle is oxygen in the air and hydrogen storage. The hydrogen in the tank reacts in the fuel cell to produce electricity and water, where the electric energy drives the engine to generate power, while the water is discharged outward in the form of water vapor and water. At present, the energy efficiency utilization rate of modern hydrogen fuel cell vehicles can reach 60%, while the traditional fuel vehicles can only reach more than 40%. Therefore, it can be seen that the hydrogen fuel cell vehicle has a very obvious advantage in energy saving and environmental protection.
The test drive was a closed-circuit test drive. The entire test drive process consisted of straight lines, S-bends, and up and down slopes, simulating most of the driving environment in daily life. In the driving process, except for the push-button shifting, the driving method is the same as that of the conventional fuel truck. When the vehicle is started and stopped with one-touch start, the sound and jitter from the engine compartment are hardly felt. The throttle and brakes are very lightweight and very sensitive during acceleration and deceleration. The acceleration and deceleration process is very smooth, there is no feeling of frustration of the fuel car, and there is no obvious push back feeling of the pure electric car. The most obvious feature is that when the speed is above 90km/h, the accelerator pedal can be heard to hear the sound of the high-speed operation of the motor.
In the case of a straight line segment, the speed of the vehicle is very fast, and the vehicle speed is straight and the body is very stable. Even if you climb a steep slope of 45 degrees or more at a speed of 30km/h, you can easily accelerate the uphill slope by simply stepping on the throttle. The whole process is the same as that of a smooth section, and the power upstream is more than enough.
It is worth mentioning that the test drive site is Korea Longren speedway, the temperature of the test drive has been below minus 10 degrees. At such a low temperature, the performance of the NEXO hydrogen fuel cell vehicle is still very good, completely without low temperature. Impact.
In addition, Hyundai Motor official also highlighted the automatic parking function configured by NEXO. When driving NEXO in the parking area, when the speed is 20km/h, the vehicle will search for the nearby parking space. When the vehicle is in the proper position, the system will prompt to open the automatic parking function. The driver only needs to press the automatic parking button. Select the parking mode, the driver can get off the car, press the reverse button on the car key outside the car, the car can be automatically parked to the parking space by parallel parking or right angle parking. The whole process is very smooth and the parking location is very precise.
At present, under the craze of pure electric vehicles, hydrogen fuel cell vehicles represented by Japan and South Korea are accelerating commercial development. In terms of technology, the future has arrived, but hydrogen fuel cell vehicles still take time from commercial operations. From the performance of the NEXO hydrogen fuel cell vehicle, it can be seen that Hyundai Motor Group still maintains a leading position in the field of hydrogen fuel cell vehicles.
