Market prospect of dual power supply technology

Most of the fuel efficiency comes from aerodynamic progress, weight reduction and the development of smaller and more powerful engines. In fact, any car can greatly improve its mileage by reducing its engine volume. The reason why this improvement has not been made is mainly at the request of users, who need more horsepower and agility.

But in addition to better fuel economy, hybrid vehicles also have many advantages in environmental protection. In big cities with extremely bad environmental pollution, hybrid vehicles can greatly change the environmental conditions, because they will only produce very little exhaust emissions during slow driving and peak hours.

At present, the United States has just started to produce hybrid cars, and Japan is the leader. Honda and Toyota have become the two largest hybrid car giants in the world with their respective Insight series and Prius series. -Mercury Mariner, a new hybrid car recently exhibited by General Motors, admitted that they had to obtain more than 20 independent patents from the Japanese.

Industry analysts believe that the hybrid car industry in the United States is still in a symbolic stage, rather than trying it in the market with a serious attitude. The reason for the rise of this industry is closely related to the average fuel consumption regulations of American automobile manufacturing industry. Current standards require that the average mileage of all vehicles sold by automobile manufacturers should reach 27.5 miles per gallon. This means that if they sell 65,438+0 hybrid cars with a mileage of 60 miles per gallon, they can allocate four slightly inefficient cars, such as SUVs and trucks, with a mileage of only 20 miles per gallon.

In view of the high initial cost and marginal saving of gasoline, the manufacturers of hybrid vehicles mainly rely on two selling points: "environmental protection" image and "new" technology.

The engines and batteries of these hybrid vehicles do not need maintenance during the service life of the vehicles. Because hybrid vehicles have regenerative braking function, brake pads are more durable than other ordinary vehicles.

In short, compared with the tallest gasoline-powered vehicle, the fuel economy of hybrid vehicles can be reduced by as much as 25% to 35%. At the same time, another powerful factor in buying a hybrid car in the United States is tax reduction-it can help you reduce the cost by as much as $3,400 depending on the cost of the vehicle.

Experts believe that hybrid vehicles may be just a transitional technology in the end. Hydrogen or methane fuel cell drive is the future of automobile industry. For environmental protection, there are many ways to reduce emissions-bus, car sharing, cycling instead of walking and so on. Just buying a small, low-consumption car can also bring considerable benefits.
