Should I buy a car with a diesel, gasoline or hybrid engine?

So that users can decide which car to buy between three engines: gasoline, diesel or hybrid gasoline, the article will specifically analyze the usage, selling price, maintenance and repair costs and fuel economy of the above car models to make optimal choices for themselves.

About the operating principle

The difference between the three types of vehicles is the car engine – the device that converts various forms of energy into kinetic energy to help the mechanism move. Each type of engine: diesel – gasoline – hybrid has different characteristics in terms of carburetor, design, number of cylinders, fuel used, engine speed, operating principle and cycle.

Gasoline engines are one of the most popular engines today. The engine uses gasoline as the main fuel to operate, the mixture of gas and gasoline creates compression pressure that is ignited by the spark plug to create an electric spark. From here, a large amount of heat is generated to help the piston move, creating the rotation of the crankshaft transmitted to the gearbox to make the wheels roll.

In contrast, diesel engines use oil as the main fuel, which is injected into the combustion chamber during the transition between the compression and combustion-expansion strokes. No spark plugs are needed, the compressed air will self-ignite when the pressure is high.

Completely different from internal combustion engines such as gasoline or diesel, cars with hybrid engines are also called hybrid cars because they combine 2 engines at the same time: gasoline engine and electric motor. Electric motors create kinetic energy using electrical energy based on the phenomenon of electromagnetic induction, electricity is stored in the generator and taken out for continuous use.

According to research, hybrid engines have fewer problems than gasoline and diesel engines when surveyed with 47,013 customers. The data shows that the errors that hybrid engines encounter are only average and less serious, so users will not spend too much time repairing.

Price of gasoline, diesel and hybrid motorbikes

Of the three engine types, hybrid cars are the most expensive because of their complex engine design, integration of modern technology and fuel economy. The most popular hybrid car model in the Vietnamese market, also the first popular hybrid car to appear in the popular segment, is the Toyota Corolla Cross 1.8HV version with a listed price of over 955 million, 90 - 100 million higher than the same gasoline engine versions.

Coming in second place is the car model using diesel engine because of the special features in the structure system and machine parts. The internal parts of the engine are meticulously manufactured, complex and require high technical requirements, so the price of diesel engines is always higher than that of gasoline engines.

Fuel consumption and environmental friendliness

The specific fuel consumption of a diesel engine is lower than that of a gasoline engine and the efficiency is 1.5 times higher. Besides, diesel is cheaper and can withstand loads better, so it is the choice of many people who need to move a lot.

However, gasoline engines are lighter in weight at the same power, cheaper to manufacture, resulting in lower selling prices and faster engine speeds than diesel.

In terms of fuel economy, the hybrid engine is at the top, followed by the diesel engine and finally the gasoline engine. Especially when driving around the city, the hybrid engine maximizes its advantages.

Hybrid vehicles are the most fuel-efficient thanks to the use of energy from the HV battery, which can provide power in all four modes: starting mode, acceleration mode, normal road travel mode and deceleration mode.

Take the Nissan Kicks hybrid for example, a car that is currently the most fuel-efficient. In urban areas, the car only consumes 2.2 liters/100 km, and outside urban areas, it only consumes 6.1 liters/100 km.

Nissan Kick is the most fuel-efficient hybrid car today.

In the context of climate change causing serious consequences globally when a series of unusual natural phenomena occur, the application of hybrid engines is one of the major steps to reduce polluting emissions into the environment, especially in large urban areas.

If the car is fully charged, the hybrid engine hardly uses the combustion process, so very little gas is released into the environment. Therefore, hybrid cars are predicted to be the change of most car manufacturers to keep up with the times. According to research, cars using gasoline hybrid engines emit about 24% less than gasoline or diesel.

About maintenance and upkeep costs

Internal combustion and diesel engines are generally more expensive to service and maintain because they have higher compression ratios, which require precision and meticulous design of machine parts. This results in higher repair costs because specialized machines and skilled workers are needed.

Diesel engine maintenance costs more than gasoline and hybrid engines.

The maintenance cost of a hybrid engine is the lowest compared to an internal combustion engine, mainly focusing on the battery because electric vehicles use Lithium-ion batteries. Lithium-ion technology only holds energy to a certain level and gradually degrades so it needs to be recharged.

Basically, hybrid batteries do not require regular maintenance, the part that needs regular maintenance is the air filter in the battery cooling system. This air filter needs to be cleaned every 10,000 km and replaced every 30,000 km. Thus, using a hybrid vehicle will save a lot of maintenance costs compared to lines using gasoline or diesel engines.

Deciding whether to buy a diesel, petrol or hybrid car?

If you want to experience a smooth and gentle feeling, a gasoline engine is the perfect choice. Vehicles using gasoline engines have the advantage of high capacity, good acceleration due to light weight and low noise, providing the smoothest and most refreshing journey.

Gasoline engines are suitable for those who want to buy a personal or family car because they do not need to travel much and do not place a heavy emphasis on fuel costs.

Diesel engines generate higher torque even at low rpm, so they have significantly stronger pulling power. Compared to gasoline engines, diesel engines are 1.5 times more efficient. Therefore, this is the choice for those who need a solid driving feeling and often travel on difficult and complex terrain, such as off-roading.

Diesel-powered vehicles are especially suitable for owners who often carry heavy loads, requiring a sturdy and load-bearing engine. At the same time, diesel engines consume less fuel than gasoline engines despite having the same engine capacity, so they save fuel costs. If you want a vehicle that operates stably for a long time, this is the best choice.

With hybrid cars, most models use automatic transmissions, making them easy to operate. In addition, the engine when running on electricity is very quiet and people in the car can hardly hear the engine noise below.

Hybrid engines are more flexible because they can be used to move within the city to go to work, school or travel long distances, requiring high speed. For vehicles that only use a fully electric engine, you should consider if you want to travel long distances because it is difficult to find a charging station.

When deciding to buy a gasoline, diesel or hybrid motorbike, users need to carefully consider personal preferences, intended use and current financial level to make the most appropriate choice.
