The Science Behind Your Vehicle’s Powertrain

4 min read


You may not know it, but there’s a lot of science behind your vehicle’s powertrain. The powertrain is the part of an automobile that transmits mechanical power from the engine to the wheels. It includes not only the engine and transmission but also other parts like drive axles, differentials, and even auxiliary equipment like air conditioning compressors. In this article we’ll explore how each component works so you can understand how they work together to make your car go!


The vehicle’s powertrain is made up of the engine, transmission and drive axle. The engine is responsible for producing horsepower, which is transmitted to the wheels via a gearbox and differential. The drive axle transmits torque from the differential to rotate both wheels on opposite sides of your car at once.

The first application of a four-wheel drive system was developed in 1904 by Ferdinand Porsche but did not see widespread use until after World War II because it was difficult to control due to the lack of electronic controls available at that time. Today’s modern 4WD cars have sophisticated systems that can automatically engage or disengage depending on road conditions or driver input; however there are still many older cars on our roads today without these features so watch out!

Gasoline Engine

The compression ratio is the amount of air that can be squeezed into a cylinder. The more air, the more fuel you can burn and the more power your engine will make. The higher this number is, the better off your car will be–but there are limits to how much you can increase it before things start getting dangerous.

The difference between a high-compression motor and one with low compression is clear when looking at cylinders:

  • A high-compression motor has shorter pistons that compress less than those in low-compression engines do (which means less space between top dead center and bottom dead center).
  • A high-compression motor has smaller valves than those found on low-compression motors because they don’t need as much airflow to keep them cool during operation.

Diesel Engine

Diesel engines are more efficient than gasoline engines. Diesel engines have a higher compression ratio than gasoline engines, which means they can make more torque with less fuel. This allows the engine to turn at higher RPMs without losing efficiency, which results in better performance and fuel economy.

However, diesel engines are more expensive than gas-powered ones because they require special parts such as an exhaust system that can handle high temperatures and pressures associated with burning diesel fuel (which produces less CO2 than gasoline).

Hybrid Engine and Battery Power

Hybrid vehicles are powered by an internal combustion engine and an electric motor. The hybrid system uses both power sources to provide the most efficient use of energy, with the electric motor assisting in acceleration and braking and recharging the battery pack as needed. When you accelerate from a stop, for example, your car’s gasoline-powered engine turns on first while its battery pack charges up; once you reach cruising speed (about 20 mph), it switches over to using only electricity from its own batteries. This allows for better fuel economy overall since you’re not burning gas at every opportunity; instead, there are times when no fuel is used at all!

Electric Vehicle (EV)

Electric vehicles (EVs) are powered by electricity stored in batteries. Batteries are made up of cells, which contain lithium-ion technology. The most common type of EV uses a battery pack that can be recharged from an outlet or charging station and may have a range of 100 miles or more before it needs to be recharged again.

EVs produce no tailpipe emissions because they don’t burn any fuel like gas-powered vehicles do. This makes them much cleaner than traditional cars, but they do require electricity to run–so if you’re going to buy an EV, make sure your home has access to reliable power sources!

In addition:

  • EVs are more efficient than gas-powered vehicles because there’s less energy loss during transmission; this means you’ll save money on gas over time too!
  • The initial cost for purchasing an EV will likely be higher than buying a comparable size gasoline powered car due to high initial costs associated with developing new technology such as batteries themselves along with infrastructure required such as charging stations needed across cities where these types exist today versus older style engines being able to run off old fashioned internal combustion engine technologies already established throughout decades past when first introduced into mainstream markets worldwide back then before becoming popularized throughout many parts around globe today thanks largely due largely driven demand increasing steadily alongside growing population growth rates globally year after year since late 1800s onward continuing upwards exponentially ever since through present day 2030s onward…

Automotive powertrains are complex machines that you can trust to work for you.

Automotive powertrains are complex machines that you can trust to work for you. They’re built to last, durable, and designed with your safety in mind.

Powertrains are made up of many components that work together to provide the power needed to move a vehicle forward or backward. Each component has its own function: one part might be responsible for turning fuel into energy while another converts this energy into rotational motion via an axle shaft and drivetrain gears. A transmission then sends this rotational force out through the wheels so that you can drive safely down the road!
