As one of the “Japan’s top three”, Nissan in China is not as distinctive as two other comrades-in-arms-it does not learn Toyota to talk about the golden mean, and it is not like Honda’s main sports style. Nissan fans often cannot describe the brand in a highly generalized sentence, but it does not prevent it from occupying a long-term place in the market and users. Nissan is such an amazing brand with both the Nissan Sylphy occupying the compact head row, the mid-level benchmarking nature, and the ten-year-old myth GT-R.
Looking back at Nissan’s technological development, Nissan has a deep accumulation in the traditional fuel oil field, the development of electric vehicles, and intelligent technology.
No doubt, no one will doubt Nissan’s engine technology. The first generation of Shenji VQ series engines has been awarded the “Ward Top Ten Engines” for fourteen consecutive years. Starting from the first VQ engine born in 1994, each VQ series The engines have the same DNA. The VQ engines have the characteristics of high efficiency, quietness, smoothness, light weight, high compatibility and high reliability. Whether it is VQ20DE or VQ35DE, the VQ series engines can be said to be the most technically “Nissan” Good proof.
Nissan’s strength in internal combustion engines does not hide Nissan’s achievements in new energy. As early as 1947, 73 years ago, Nissan launched the first electric car. After the end of World War II, oil was very scarce, but electricity was plentiful. The Japanese government encouraged the development of electric vehicles. With the encouragement of policies, Nissan Tama electric vehicles were born, with an endurance of 97km and a top speed of 35.2km / h. This figure may look slightly inferior today, but it must be taken into account that it is a model 70 years ago.
With 70 years of Nissan electric vehicle R & D and manufacturing experience, and more than 25 years of automotive battery R & D and manufacturing experience, Nissan’s most representative product in the field of electrics, Lingfeng, has consistently ranked first in the world’s cumulative sales of electric vehicles. Already has more than 400,000 vehicle owners, and maintains a record of 10 major accidents with a total of 10 billion miles of batteries.
In the new era, Nissan has also made new innovations in technology. Nissan has been promoting Nissan Intelligent Mobility around the world since the end of 2017, which is “Nissan Intelligent Mobility”, which includes intelligent driving, intelligent power and intelligent interconnection.
And this is not just a slogan, we can see the VC-Turbo super-variable engine on Nissan Teana. It is one of the biggest innovations in automotive power systems in the past decade. When the two fields were moving, Nissan walked out of its own black technology line. In fact, it is not surprising to do so, because no one would doubt Nissan’s leading position in the engine field.
From the VG engine series to break the Japanese dilemma without V6, to the RB series with the GT-R reputation, to the generation of God machine VQ series engines for the 14th consecutive year won the “Top Ten Engines”. In the new era, the VC-TURBO Ultra-Continuous Engine continues the powerful performance of the VQ series and once again wins the affirmation of “Top Ten Engines from Ward”.
Strict emission standards reflect the public’s demand for efficient and environmentally friendly power. Many current models achieve emission standards through the installation of exhaust gas treatment devices, but the exhaust gas treatment can only be passively assessed, and cannot achieve the goal from the root cause. VC-Turbo Super Variable Engine can quickly determine the driver’s need to adjust the compression ratio in the cylinder through variable compression ratio technology, and continuously and continuously switch between 8: 1-14: 1. In conjunction with turbocharging technology, while ensuring smooth and smooth power output, the fuel efficiency is improved to the extreme. Not only the fuel consumption is greatly reduced, but the emissions are correspondingly reduced, which is enough to meet the national six emission standards.
The core principle of Nissan VC-TURBO is to add a newly designed multi-link connecting mechanism to the traditional piston structure, and use the control shaft to change the structure of the multi-link system to increase or decrease the piston stroke. Intention, different working conditions, intelligent selection of the best compression ratio between 8: 1 to 14: 1, solving the traditional contradiction between power and fuel consumption, achieving “fish and bear paw”, and gaining a history of internal combustion engine technology Sexual breakthrough.
As the two black technologies of the automobile power system, I can’t help but fall into myth: if you want to buy a car, choose the super variable engine or the dual engine? As the benchmark model of the Japanese, who is more worthy of choice for the Teana VC-Turbo Super Cam and Camry Dual Engine?
Let’s first look at the hard data. The maximum power of this Nissan Teana VC-Turbo 2.0T engine reaches 252 horsepower, the peak torque reaches 380 N · m, and the acceleration time of 0-100km / h takes only 6.42 seconds. The Camry Hybrid uses a hybrid system consisting of a 2.5L naturally aspirated engine and an electric motor. The system has a combined maximum power of 218 horsepower, a maximum hybrid torque of 213 N · m, and 0-100km / h takes 8.3 seconds. In terms of dynamic performance, of the three major Japanese models (Nissan Teana, Honda Accord, and Toyota Camry), only the Nissan Teana VC-Turbo Super Variable Engine ran into 7 seconds. In the entire mid-range car category, the performance of 6.5 seconds was also very good. Obviously, if you want to exercise and need power, Nissan Teana VC-Turbo Super Variable Engine is more worthy of choice.
In terms of fuel consumption, the Toyota Camry hybrid is very fuel-efficient, with an average of 5.5L / 100km, while the Nissan Teana with variable compression ratio technology has a fuel consumption of only 6.6L / 100km. If you consider the purchase cost, the Toyota Camry Hybrid (guide price 23.98 10,000 yuan, 242,800 yuan, 279,800 yuan), Nissan Teana 2.0T (guide price of 216,800 yuan, 229,800 yuan, 268,800 yuan), Camry hybrid price is more expensive than Nissan Teana 10,000 yuan, including taxes Wait for about 10,000 yuan. Rough calculations, the Camry Hybrid will need to add less 50 tanks of fuel to be cost-effective. Obviously, from the perspective of cost, the cost savings of hybrid electric and electric vehicles are not significant compared with the extra car prices.
Nissa Teana has not only super variable engine but also super intelligent driving. ProPILOT can realize L2 level automatic driving assistance function, and can complete steering, acceleration and braking operations in fully automatic mode. Compared with other driving assistance systems, ProPILOT super intelligent The driver can drive in the center of the lane line, adjust the direction before “touching” the lane line, and control the acceleration according to the radius of the curve to ensure the comfort of the passengers in the car.
In addition to ProPILOT, Teana is also equipped with the NISSAN i-SAFETY intelligent active safety system, which can achieve 360 ° monitoring and early warning, and quickly avoid danger through intelligent alarm and automatic braking.
In the second half of 2019, Nissan released version 2.0 of ProPILOT. Both hands can drive in a single lane without the steering wheel. Based on the navigation information on the highway, Nissan can assist in parallel overtaking and assisting in driving out of high-speed. ProPilot 2.0 can even change lanes to exceed slower cars. The system will prompt the driver to put their hands back on the steering wheel, then the system will automatically perform a lane change, pass another car and return to the original lane.
The latest Camry is also equipped with Toyota’s latest Toyota Safety Sense, which works through millimeter-wave radar + camera, including PCS pre-collision safety system, LDA lane departure warning system, AHB automatic adjustment high beam system and DRCC dynamic radar cruise. Control System.
Don’t forget, Tianli also has a “big sofa plus”. There are three core technologies for the comfort of the Tianli seat. The new-generation Multi-Layer ergonomic seat. The so-called “ergonomics” mainly refers to the more even distribution of backrest pressure. , Will not focus a part of the force, thereby alleviating driving fatigue. In terms of ride comfort and space, the Teana performs better than the Camry.
Regarding the future power system, Nissan also introduced e-POWER intelligent charging technology. The powertrain integrates a gasoline engine, inverter, battery and motor. Among them, the gasoline engine is only responsible for generating electricity, so the engine can always be kept in the best working condition, compared with the traditional internal combustion engine, it can provide good fuel economy and lower emissions.
The e-POWER system is driven by a full electric motor, which means that the wheels are driven entirely by the electric motor. Power from high-output batteries is delivered to e-POWER’s compact powertrain, including gasoline engines, generators, inverters and electric motors.
In traditional hybrid systems, when the battery is low (or driving at high speeds), a low-output motor is used in conjunction with a gasoline engine to drive the wheels. However, in the e-POWER system, the gasoline engine is not connected to the wheels; it just charges the battery. Unlike traditional electric vehicles, the power in e-POWER comes from the engine, not just the battery.
In addition to e-POWER, Nissan has innovated in driving operations and introduced a single-pedal operating system e-Pedal. Users can accelerate, decelerate and stop the car through a single electronic pedal. E-Pedal can meet 90% of the driver ’s Operational requirements.
In terms of front-end technology, Nissan’s “Brain to Vehicle (B2V)” can enable the vehicle to interpret the signals sent by the driver’s brain, and can more quickly communicate the driver’s response to the vehicle, enabling the vehicle to follow the driving Changes in the situation constantly make corresponding adjustments to make the driving process more interesting. In addition, invisible-to-Visible technology helps drivers see the “invisible world” by integrating the real and virtual worlds, and even displays the situation behind or around the surrounding buildings, making it easier and more convenient for drivers to drive. Safety.
No matter in the past, now, or in the future, Nissan Black Technology has always been around to give people more convenience, more safety, and more surprises.
With the VC-Turbo ultra-change engine added to the nature, compared with the other two Japanese cars in terms of power, it can be said to be a perfect ride. Not only is the power outstanding, but it is also important to consider the fuel consumption level. Moving is more athletic and driving passion. In terms of driving safety, the nature of ProPILOT has become smarter. It can actively avoid risks and make driving more at ease. With the tradition of a “big sofa”, it feels more comfortable to ride.
