"Hey, Keke, did you work hard?"
"Hehe, hehe..."
"Well, the progress of this and this needs to be accelerated. The R&D center is progressing very quickly now, and you guys have to keep up."
"I know...I know,"
Looking at Cheng Ke who was playing with his fingers so enthusiastically, Li Fanyu almost had the urge to cover his face.
You looked so arrogant just now, but now you look soft and soft in the blink of an eye.
You're acting like this... it's a foul, you bastard!
Hey,
I can’t communicate with such a girl!
Sighing, Li Fanyu said a few words and left as if running away, leaving Cheng Ke alone to become a big man.
Li Fanyu, who came out of the Expo Park, inspected the industrial park and found that most parts supply companies were facing similar situations to Boyuan - facing the R&D intensity of three cars at the same time, they obviously could not keep up. Rhythm.
Seeing this situation, Li Fanyu realized how useful the second phase industrial park was. But there is no way, the second phase is still under construction, and it will take seven or eight months at the earliest to be delivered for use.
When new retail companies enter, I am afraid it will take a year.
Far water cannot quench near thirst, so we can only look at plum blossoms to quench thirst,
So Li Fanyu can only keep telling the following companies how huge the SUV market is, how broad the prospects are, and how much profit it will bring to the entire industrial park. Then Xiaozhi moved them with emotion and reason, asking them to work quickly to catch up with the progress.
Every company knows these things, but Li Fanyu emphasized it and clarified the huge interests as the driving force, and the progress suddenly moved forward.
With this intensity, a month passed quickly.
Because it was the first time in Zhengxin’s history to develop three products at the same time, the entire R&D process seemed a bit rushed. Due to the capacity limitations of the spare parts supply companies, the entire R&D process could even be said to be a bit chaotic and chaotic.
However, with joint efforts, each team still showed amazing explosive power.
The three models of Tiguan, Q5 and Land Cruiser were successfully born amidst much external discussion and internal busyness. After the last internal test, the three vehicles were finalized and sent to the Ministry of Industry and Information Technology for review.
In terms of class distinction, Tiguan, which was developed on the PQ front-engine platform as a compact SUV, finally determined the overall vehicle size at 4605mm, 1809mm, 1685mm, and the wheelbase was set at 1689mm. This size actually does not strictly comply with the design data given by Li Fanyu. Instead, Wang Yu appropriately increased the length, width and wheelbase through communication with the Zhengxin Marketing Department.
This change directly makes the Tiguan class a foul, surpassing 90% of its competitors in the compact class on the market.
Because Li Fanyu’s original positioning was to define Tiguan as a compact SUV with a mass-market nature. To put it bluntly, it was to create more sales and obtain more mileage, in order to coordinate with the double R&D points of space. Added new buff. Therefore, we agreed to this change to cater to the market.
This is size wise.
In terms of power, the gasoline version is equipped with Zhengxin’s mature ZGX888, a 1.8-liter inline four-cylinder turbocharged engine. In order to obtain better ride comfort and reduce costs, Wang Yu did not use a dual-clutch gearbox according to the original design of Li Fanyu's drawings.
Dual-clutch is definitely a good thing, but now Zhengshin only installs the enhanced version of this gearbox on RS and Longbow. There is no precedent for it being installed in a mass-produced car, so it is impossible to know how effective this thing will be after being simplified.
This thing is definitely good, but the RS and the Longbow are both delicate performance cars, which are different from the Tiguan. Dual clutches are expensive and inconvenient to maintain. Wang Yu’s idea is that since he wants to gain volume, he doesn’t need to use fancy new technology as a selling point.
So he replaced the Tiguan with a 6AT automatic transmission that was cheaper, more reliable and durable. Apart from this, the rest of the configuration completely follows Li Fanyu’s original design drawings.
As for the diesel-powered version, the TDI diesel turbocharged engine developed by the team led by Li Fanyu himself is installed on the Tiguan.
This diesel engine uses high-pressure direct injection technology, because it cleverly utilizes the concave bowl shape on the top of the piston, so that the high-pressure fuel will be similar to the W12 electronic turbocharged engine that Wang Rui modified before. The high-pressure fuel is allowed to form a spiral mixture of oil and gas inside the cylinder, which improves the combustion in the cylinder and greatly reduces the content of harmful particles in the emission process.
Although the development time was very tight, Wang Yu still studied this engine carefully. The pump-injection principle and the adjustable vane turbocharger have never appeared in Zhengsin's previous engines.
After the engine test results were obtained, Wang Yu was surprised to find that using the pump injection principle and adjustable blade technology, the TDI engine can better control the fuel injection volume with the cooperation of the ECU, greatly improving fuel efficiency. Compared with several common diesel engines of the same displacement on the market, the power of TDI has increased by about 20%. However, despite the increase, the fuel consumption and the amount of carbon dioxide produced by combustion have not increased but decreased.
This is awesome.
But the advantages of this engine don’t stop there, because unlike the ZGX888 series gasoline engines that require the use of spark plugs for ignition, TDI uses high pressure to allow air to self-ignite, thus eliminating the cost of spark plugs in structure. cost. Specifically for consumers, it saves a lot of money on replacing spark plugs.
This is even more powerful.
Through the horizontal comparison with the diesel version of the engine, even though Wang Yu is aware of the technical excellence of the ZGX series engine, he has to affirm that the diesel version of the Tiguan has certain advantages over the gasoline version when measured comprehensively.
The only thing that worries him is that there are too few compact SUVs equipped with diesel versions on the market. When biodiesel has not yet become popular, will the diesel version of Tiguan encounter the same embarrassment as the diesel version of the Fighter?
It’s not surprising that he’s worried. You have to know that the Fighter is fundamentally a work pickup truck. The Tiguan is an authentic family SUV. Therefore, the Tiguan, which is equipped with a diesel engine that has slightly poor high-speed performance but is powerful and fuel-efficient, may not be as good as the Fighter in terms of objective conditions.
After conducting small batch trial production and cost accounting, Wang Yu was pleased to find that the cost of Tiguan was not bad.
The final cost of the entire vehicle is 62,000 and 74,000 respectively for the two power versions of the gasoline engine using the same interior design. The diesel 2.0TDI powered version costs 65,000.
Such a cost gives the TDI diesel version a certain advantage in selling price.
