Who can win the future heavyweight truck industry with LNG vehicles compared to diesel vehicles? (1)

As a representative of emissions and environmental protection, the momentum of LNG models in recent years has not been as strong as initially expected. Even though the government has been vigorously promoting them recently, the results have been minimal. Many truck drivers are still hesitant to make a decision to buy them, and the development trend of LNG heavy-duty trucks in 2019 is still slow.
On the other hand, the country is constantly advocating for environmentally friendly emissions, and diesel vehicles are constantly upgrading their emission standards, leading to a gradual increase in their maintenance costs.
For drivers who often drive sports cars, choosing between LNG or diesel cars is a big question. Which one has a brighter future?
Who should I choose between LNG and diesel models?
Firstly, from a policy perspective.
The country has been vigorously developing LNG heavy-duty trucks. In just this year's time, diesel vehicles have been upgraded from national level three to national level six, causing many car enthusiasts who are preparing to lift diesel vehicles to a halt.
If you want to raise the standard again, models that do not meet the emission standards must be eliminated, and buying a new car also requires a cost. Running a big car is originally for the sake of making money, and it is not long before the car is purchased and the cost is not recovered that the model should be updated. It is also a worry to think about.
So, when environmental protection becomes a future emission requirement, the future of LNG heavy-duty trucks fueled with pure methane can be expected. It has low pollution after combustion, and emission upgrades are very easy. Although there is also a risk of being phased out later, compared to diesel cars, the probability is much lower.
