To choose to buy the right car, in addition to paying attention to the brands, models, models, and basic specifications, it is also an important issue to pay attention to. A car basically has a lot of specifications:   size, capacity, engine, transmission, drive, safety equipment, etc.

In this article, we will learn together the basic specifications on cars.

1. Overall size:

Overall dimensions include length, width and height. This is the size from the top of the car to the bottom of the car, from the roof to the bottom edge of the wheel and from the left edge to the right edge. This size will tell the buyer whether this car belongs to the “type” of small, compact or tall, superficial.

2. Base width:

– The wheelbase is calculated as the distance from the center of the left tire to the center of the right tire. The larger the wheelbase, the higher the stability of the car and the easier it is to control. But when the wheelbase is large, it will affect the ability to move in narrow and cramped roads.

3. Wheelbase:

The wheelbase is the distance from the center of the front wheel to the center of the rear wheel.

The larger the wheelbase, the more stable the car is when moving as well as increasing the interior space to create a more comfortable feeling. The larger the wheelbase, the more spacious the passenger compartment.

4. Minimum turning radius:

The minimum turning radius is created by turning the vehicle all the way around and is calculated from the center of the revolution to the outermost wheel.

Minimum turning radius

The smaller the minimum turning radius, the better, the easier it is to navigate in narrow roads.

5. Ground clearance:

Ground clearance is the distance from the ground to the lowest point of the vehicle. The ground clearance tells the viewer what type of road the vehicle is suitable for, the ability to wade through the water, the ability to overcome obstacles, etc.

6. Cylinder capacity:

Cylinder capacity known as the number of “dots” of a car (1.0, 1.5, 2.0, …) is the volume of the cylinder swept by the piston when going from the top dead center to the bottom dead center of the engine.

For a 1-cylinder engine, the engine displacement is also the cylinder displacement. As for a multi-cylinder engine, the engine displacement is the total capacity of the cylinders.

Usually cylinder capacity tells us about the size of the engine. The larger the cylinder capacity, the more air the cylinder can load, the greater the energy generated in the combustion process, the higher the work output, the stronger the engine and of course will also consume more fuel.

7. Power, torque

Power and torque are the units that express the power of a car. The higher the power, the greater the power of the engine and the vehicle. The higher the torque, the greater the load capacity, the more powerful the vehicle, and the faster acceleration.

8. Gearbox

A gearbox is a system consisting of many pairs of matched gear sets, used to transmit torque from the engine to the driving wheels of a car. The function of the gearbox is to change the torque and speed of the engine, helping the car to move and operate flexibly. There are 4 common transmission types including: manual transmission (MT), automatic transmission (AT), continuously variable transmission (CVT), dual clutch transmission (DCT) with different characteristics, we will be clarified in the following articles for easy reference.

9. Powertrain

This is the system in the vehicle that connects the transmission or transmission to the drive shaft and is divided into three main categories:

  • Front-wheel drive (FWD)
  • Rear Wheel Drive (RWD)
  • All-Wheel Drive (4×4 / 4WD / AWD)

Being able to see the vehicle’s specifications will save you time and money when buying a car. Knowing the differences in engine type, transmission, and safety features in your vehicle can ensure that you get the right vehicle for personal, business or family use.
