When it first began to contact with the West, Mercedes-Benz heavy trucks were good at NG73 heavy trucks across the era, and a batch of domestic imports was also NG73 heavy trucks, and the imitation of the Iron Horse Factory was actually NG73 heavy trucks.

Later, when the official inspection of the eastern countries and the need for technology introduction were proposed, they had been upgraded to NG80 heavy trucks, which belonged to upgraded products, not a complete replacement, but there were a lot of improvement projects, including the engine, including the chassis, and even the cab was improved, reducing wind resistance and so on.

Any factory, if it only stays on the past achievements and sleeps, will always be eliminated.

Of course, the domestic exception, in the era of planned economy, the old liberation of production for 30 years, still has not been eliminated, but in the future, with the continuous development of the market economy, we can see that many state-owned car companies continue to regress, while private car companies are making great strides.

The reason is naturally the ability to innovate, when a state-owned enterprise spent 50 billion yuan to research out a tall car, in fact, most of it is still surveying and mapping, private enterprises used a fraction of their R & D costs, and the product was upgraded.

Continuous research and development, continuous upgrading, will have progress, lying in the past to sleep, is absolutely not good, just like upgrading from the fifth to the sixth, many car companies lack the research and development capabilities, there is no six vehicles to sell, as a result, it will naturally go out of business.

Mercedes-Benz heavy trucks are of course constantly upgrading and progressing, in 1980, the launch of NG80 heavy trucks, and in recent years, the results of research and development have accumulated together, has been intended to further launch new heavy trucks, plans to wait until the New Year on the official market, code NG85.

The reason why Mercedes-Benz heavy trucks can agree to these requirements of a machine factory, of course, also has their own small ninety-nine, the export technology is NG80 series heavy trucks, which has been making money for five years, and the newly listed NG85 heavy truck technology is absolutely unwilling to take it out, Qin Zhenhua is just making fun of the other party here.

NG85 series of heavy truck upgrades, progress is considerable, in terms of engine, the improved V8 engine, has been able to output 375 horsepower power, if placed in the future, this is nothing at all, but now, is definitely the first in the heavy truck engine.

Not only is the power strong, but also takes into account the fuel consumption, which even a professional diesel engine company like MTU cannot match.

The newly developed OM442LA engine is even more powerful, this V8 engine uses supercharged intercooler, with a displacement of 14.6 liters and a maximum output of 430 horsepower, and this engine is also used in the follow-up Mercedes-Benz SK model.

At the same time, they also have an 18.3-liter V10 engine with a maximum power of 355 hp and a turbocharged version with 500 hp.

A civilian car, equipped with a 500-horsepower engine, is definitely an anti-heaven existence!

However, in the progress of technology, the progress of the engine has been shrouded by the progress of another technology, which is the transmission!

In this era, heavy trucks are all manual transmissions, and only tanks will use expensive hydraulic transmissions with the ability to automatically shift gears, but this has not been transplanted to ordinary civilian vehicles.

Because it has a torque converter in it, this thing will consume power, and heavy trucks that pursue economy cannot use this technology.

And Mercedes-Benz did not give up, liberating the left foot is a great effect, the frequent start of heavy trucks, deceleration, is quite a heavy burden on the left foot.

You know, the heavy trucks of this era have popularized the nine-speed gearbox, and for a start and acceleration, you have to switch nine gears and step on the clutch pedal nine times!

Therefore, when Steyr heavy trucks entered the country, the old drivers invented the way of not stepping on the clutch to shift gears, completely relying on the throttle to cooperate, except for stepping on the clutch when starting, other times, are not stepped, this way, not only saves the life of the clutch, but also reduces the delay of power.

Especially in the case of heavy load uphill, it takes a certain amount of time to step on and loosen the clutch, which causes the loss of power, which may cause the vehicle to be unable to continue walking on the ramp.

European transportation has been very perfect, there will be no overload, they pay attention to the comfort of people, so, in order to make the driver more comfortable to drive the vehicle, Mercedes-Benz heavy truck company has also developed a new set of automatic transmission, named Electronic power shift (electronic power shift), which is also the first in the heavy truck industry, supplied in the 1644 flagship model.

Of course, although after several years of research and development, the gearshift logic of this transmission is still immature, but it is still a great innovation, and it is the future PowerShift automatic transmission that lays the technical foundation.

It does not use a torque converter and other devices, it is a set of computer-controlled automatic shift mechanism installed on the basis of the original manual gearbox, in fact, it is an AMT gearbox, and the setbacks of this gearbox are inevitable, but after all, this is already a good start!

Mercedes-Benz has always been a secret, there is something new, it has to be publicized, showing off its heavy truck factory technology is the world's first.

Therefore, these technologies of theirs have long been publicized, and it is normal for Qin Zhenhua to know about them.

"We are very interested in the automatic shift technology that you are working on, and we hope that these technologies can also be introduced, and they can be equipped according to the standard of the Model A." Qin Zhenhua said with a smile.

If you get it, you will be able to disassemble and study, and after disassembling and researching, you will be able to imitate it, and if the military vehicles are made into automatic transmissions, it will definitely greatly reduce the operating burden. Moreover, it can also be made into a technical reserve, and its own military-to-civilian project is a heavy truck, so it is natural to aim at the world's most advanced heavy truck technology.

As soon as he said this, the two people on the other side looked at each other, and no one was speechless.

"This piece is good, Qin, do you want us to do a dance?" Mia said from the side.

Now, the business has been discussed, the two sides have reached an intention, and there will be many rounds of detailed negotiations in the future, however, Qin Zhenhua is obviously too demanding, in order not to spoil the atmosphere, Mia came out to invite the dance.

Generally, men invite women, Mia took the initiative to invite Qin Zhenhua to dance, if Qin Zhenhua didn't agree, it would be too ungentlemanly.

So, Qin Zhenhua entered the dance floor with a smile, and soon, Mia frowned, and almost screamed, don't step on my feet anymore!
