With the progress of science and technology, the cars have already become an important part in our daily life. It is known as a vehicle with four wheels and it contains an engine and that is used to move from one place to another smoothly and quickly. The cars are one of many very useful transportation methods; it gives the freedom to travel to anywhere and on anytime. In this essay I will compare and contrast this transportation method between the past generation and the present generation. This essay will focus on three key areas – engine, safety and technology.

The first area that this essay will consider is about cars engine, the most importance thing in the car is the engine which it is the thing that makes the car move. In the past, the people were just wanted a car to reach them from point A to point B, so the car engine was so simple. For instance, the mechanical engineer Karl Benz created the first car engine which it called (Benz’s engine), the automobile was motorized by a 0.75-hp one-cylinder four-stroke gasoline engine. Furthermore, the speed of car was just 16 km/h (10 mph) (1). Besides, it was not need a lot of energy and it caused lots of pollution. With the technological advances; in current generation the car’s engine is working the basic principle like in the past by air and fuel combustion to create a rotational force and move the car, but the modern cars engine has become more developed. Where it is characterized by more reliable, more efficient and more powerful than the old engines (2). Moreover, the speeds of modern cars reach up to 429km/h. In addition the modern engines can save the fuel by using new technological ways, like the direct Injection which is mixed the fuel with air within the cylinder, allowing for well control over the amount of fuel used (3). So it has made the engine more economical for the fuel emissions.

Secondly, in terms of safety, previously the number of deaths because of cars accidents was a lot because of poor safety features in old cars. But the humans tried to decrease the number of deaths by create high safety features. For example, they have created bumpers; this can absorbs the force of the collision, so it may lead to less damages. Moreover, in the 1900s, the safety glass was invented; it is made by a plastic material which it makes the glass strong and hard to break (4). At present, the modern car safety features are evolved. Like airbags that reduce the risk of injury in crashes. In addition, the Antilock Braking System (ABS), it is a safety system prevents wheels lock during braking (5). Furthermore, the modern safety built which it stops the rush of the person when car crashes happen. These modern systems have made the car more safely than before.

Thirdly, the last key area is technology. In the past and when the car was invented, it was so simple and it contained just chairs, a steering, wheels and an engine. Therefore cars evolved gradually and the humans add more options like Speed and gasoline counter, Air condition and radio. But after the technological development, cars become working on a smart system which makes the car more comfortable and more welfare. For example, Bluetooth to connect with smart devices, Navigation (GPS) is great for getting us from point A to point B, Cameras that help the drivers to parking their cars currently famous cars factories looking for new system which is called self-driving that is make the car move by itself (6). These technological inventions make the car more than just a car, it become a complete vehicle.

To sum up, I think generations have changed and cars have evolved nevertheless I believe that cars will evolve more and more, and this is the case of generations change. So now the car is one of the main things in our daily life, this is why humans always try to improve it.
