Being a hybrid、A fuel truck is in front of you，If I give you another chance，Reselect，Who will you buy？Lao Zhang next door’s answer is a fuel vehicle，If you must add your name in front，He said it was Xuanyi。

The old man next door bought a car with the concept of environmental protection and conservation，I suddenly woke up after a year，Actually，His Lei Ling Shuangqing will be in ten years time，Only in order to recover the extra 30,000 yuan seabet apppaid。Because，Friend’s Xuanyi，Better than his 4.5L average fuel consumption，It’s just 1 more.Only about 5L。Even so，This fuel consumption，It was also broken again by the arrival of the 14th generation Sylphy。

For compact family cars，Fuel economy is one of the core factors to measure whether a car is worth buying，Sylphy, which has always occupied the top three sales of family sedans、Lavida and Corolla，Although each has its own characteristics，But the one with the most accurate understanding of consumer needs，It is none other than Xuanyi。It can always understand the core changes in the market，Continuous improvement。For example, Sylphy has held five "Thousands of Miles" fuel-saving competition。From 2015’s “Three Kingdoms with One Tank of Gas”、2016’s “A Tank of Gas Across the Far East”、From “One tank of oil across the Great Northern Wilderness” in 2017 to “Return, this is my hometown” in 2018，Becomes the most vivid expression of low fuel consumption of Sylphy series models。

And September 22nd，The fifth fuel-saving race challenge has been upgraded again，Driving on the seaside road in the Bohai section of the four-day "Thousands of Miles Away·Happy Coastline" fuel-saving race，Under real driving scenarios and road conditions，Challenge the lowest fuel consumption of mainstream dual-engine products in the market，Then，What is the result？

This race starts from the border city of Dandong, Liaoning，via Dalian、Yantai、Haiyang，Finally arrived in Qingdao, Shandong，The entire line will face two major challenges，First, the journey is long，Short time，The crossing from Dandong to Qingdao，Straight-line distance 807 kilometers，The actual mileage is longer。Also，The road conditions are also complicated，Going through a mountain road、City Road、National Highway、Highway，Nissan in order to restore the actual car use scene for families，Also added some congested road sections。

First day of itinerary，Start from the Hushan Great Wall located on the bank of the Yalu River and head towards Dalian。Sit in the cockpit，We are a group of two boys who are 1.8 meters tall，The space for the driver and passenger of Sylphy is not cramped。The body width of the 14th generation Sylphy is 1815mm，Excellent among its peers。Compared to the previous generation model，The 14th generation Sylphy that strives to be more sporty，Although it still feels like a big mobile sofa，But the support should be stronger，Just the right fit and softness。The design of the central control is more refined，The storage space is well designed，For example, the middle position between the driver and co-pilot，Except gear lever，Also adds a cup holder on one side。Also，Rear seats，A middle armrest is also provided，There is no obvious unevenness seabet loginon the bottom of the foot。

Lightly press the accelerator to start，The car is responsive，You can probably feel it with just one step on the accelerator，This is an easy car to drive。The power system of the old Sylphy，The biggest impression is that it is fuel-efficient and smooth，But the new generation Sylphy，There are obvious changes when driving，Both from the perspective of power response and overall tuning style，Both are more sporty and responsive。Of course，This is thanks to its new third-generation HR16 smart engine，Optimized in many technologies。

Speaking of this HR16 series engine，Maybe everyone is familiar with it，As a star in the daily family，It’s in Xin Tida、Equipped on many models such as Blue Bird and Sylphy Classic，The number of vehicles loaded has exceeded 6 million。There is no doubt about its reliability，Now it has developed into the third generation，Based on the first and second generations，Further improved power and torque，And reduced fuel consumption。Nissan also uses technology，Breaking the three-cylinder and small-displacement turbocharging development paths of many car companies，Maintaining excellent ride comfort and quietness in the car。

During the first day of actual use，In some sections with more traffic lights，We turned on the intelligent ECO mode and ISS intelligent automatic start-stop system，Although the 14th generation Sylphy turns on the smart ECO mode，The speed will be slightly slower，But it does not affect the driving quality on congested road sections。Secondly，On a road section with more traffic lights，Use ISS intelligent automatic start and stop system，Also try to reduce fuel damage during idling。

End of the day，In more urban sections，We finally opened 3.4L comprehensive fuel consumption per 100 kilometers，Ranked fifth。

If the first day is a warm-up match，The process of getting familiar with the car。Then enter the second day，This is the real test。Just when everyone has exceeded the official comprehensive fuel consumption per 100 kilometers，When you are confident，Enter Shandong，The road conditions have become mainly national highways and roundabout roads，And often experience climbing and other road sections，The sea breeze on Huandao Road is also strong，These are all challenges to fuel consumption，Can we maintain the previous record，Everyone started to feel unsure。

At this time，The 14th-generation Sylphy’s unique active air intake grille in its class plays a certain role，It can actively open or close the air intake grille according to different working conditions，Help the engine quickly reach the optimal operating temperature，Reduce vehicle wind resistance in real time，Although you will not feel the significant difference in driving，But this small function still optimizes the vehicle’s fuel economy。

While driving on the national highway，Bumpy roads are not uncommon，seabet ioAt this time，The chassis performance of the 14th generation Sylphy is highlighted，Compared with the old model，The new front suspension is upgraded from a half-frame to a full-frame structure，Although the rear suspension adopts a torsion beam structure，But the rigidity has been greatly improved compared to the previous generation model。So when the road is bumpy，The ride quality of the 14th generation Sylphy is still very high-end，And can filter out some fine vibrations，Sometimes the shock absorption belt is not as fast as the brakes，There is no obvious "clang" and a very direct feeling of a scooter，But delicate and flexible。

On lots of mountain roads and curves，14th generation Sylphy’s IDM intelligent highway stability system，also played a very good role。It will intelligently control the vehicle's acceleration or braking slightly based on road conditions，The "nodding" or "heading up" effect produced by corresponding actions，Let a compact car feel as smooth as a mid-size car。

While driving at high speed，The 14th generation Sylphy handles tire noise and driving noise quite well，All the way，While admiring the beautiful coastline of the Bohai Sea，While listening to music，Although it is a tough game，My mood is still rendered extremely beautiful by the scenery outside the window。

On the second day’s trip，We passed through a 23-kilometer urban congestion section、41 traffic lights，52 kilometers of highway section、Challenged the most complicated driving route in history，The lowest measured fuel consumption is only 100 kilometers 4.4L，Tie with competing hybrid products！

Next two days，The convoy passed through Rushan one after another、Haiyang，Finally arrived in Qingdao，Finally，Group B3 boasts “1350km range on one tank of fuel，Fuel consumption 3.23L/100km” won the championship in the Bohai section，Successfully broke the "1050km battery life" in the fourth quarter，Fuel consumption 3.6L/100km” record，Once again set a new height in fuel economy for the 14th generation Sylphy。

From Season 1, 4.4L，To Season 4.46L，To today’s 3.23L，It can be said，Behind every amazing game data，It is 100% polishing and investment in Nissan’s technology，This number can also be called a "milestone" in the fuel power system。

Then，Leap from 4 to 3，What kind of black technology support is there?？Let’s put this question，Thrown to Nissan’s engineering designers。Same as HR16 engine，The technological changes between the third generation and the first two generations are really not the same。

The first is the addition of mirror cylinder hole spray technology。It cancels the traditional cast iron cylinder liner，Instead of only 0.2 mm thick alloy spray film。Greatly improved thermal conductivity and cooling，Increase compression ratio to 10.8：1，At the same time, it is also further improved in lightweight。

Furthermore, e-VTC intelligent seabet appelectric contact variable valve timing control technology，That is, an electric motor is added，This responds more quickly than the previous hydraulic system，The stability is also higher。Reduced pumping loss，The resistance of the intake and exhaust ducts will be reduced，The engine efficiency will be reduced accordingly。

The third black technology is TCV intelligent spoiler control technology，It is for the combustion chamberAir flow control，Make combustion more complete，Achieve the dual goals of economy and environmental protection。The next thing isEGR cooling cycle reburning system，It can control exhaust gas more finely，Reduce the maximum firing temperature，Control NOx production and reduce knocking，While achieving the National VI B emission standards，Makes combustion more complete。

Actually，This is only the low fuel consumption performance of the 14th generation Sylphy，One aspect of dynamic optimization，And its 0.26cd ultra-low drag coefficient，Active air intake grille、Lightweight body、What should IDM integrated dynamic control system have to do，This is the final process from quantitative change to qualitative change。
