This is what happens when you hit the gas - Shannon Odell


Let’s Begin…

In 2015, two men drove a Volkswagen across the US on just over 100 gallons of fuel. Their 81-mile-per-gallon performance doubled the car’s estimated fuel rating, and set the record for the lowest fuel consumption ride of a diesel car. The duo were experts in techniques that maximize fuel efficiency. So, how did their strategy save fuel? Shannon Odell explores what’s going on beneath a car’s hood.

Efficiency: EVs vs. ICEs

Internal combustion engines (ICEs) are less efficient than electric vehicles (EVs) primarily due to the fundamental differences in their energy conversion processes. In an ICE, the combustion of fossil fuels generates mechanical energy, but a significant portion of this energy is lost as heat and friction. In contrast, EVs rely on electric motors powered by batteries, which are inherently more efficient at converting electricity into motion. EVs have the advantage of regenerative braking, which recovers energy during deceleration, further improving their efficiency. Additionally, the centralized power generation and distribution of electricity for EVs can be more efficient and cleaner than the decentralized and often inefficient process of extracting, refining, and transporting fossil fuels for ICEs. These factors collectively make electric vehicles a more energy-efficient and environmentally friendly transportation option. The use of fossil fuels has well-documented and hidden costs to humans, animals, and the planet.

Converting an ICE into an EV

Converting a gas-powered car into an electric vehicle involves the removal of the internal combustion engine, replacing it with an electric motor, installing a battery system, motor controller, and charging system, modifying the electrical system for compatibility, ensuring safety features are maintained, and testing all components rigorously. It also requires compliance with legal regulations and documentation of the conversion process, but it's a complex, costly, and specialized endeavor typically done by experts or dedicated enthusiasts.

Not just good for the planet
Most people know that EVs are better for the environment overall. But there are ton of ways that EVs beat out their ICE competitors.

- Lower Operating Costs: EVs are more energy-efficient than internal combustion engine vehicles, and electricity is often cheaper than gasoline or diesel fuel. This results in lower operating costs over the lifetime of the vehicle.

- Reduced Maintenance: EVs have fewer moving parts than traditional vehicles, which means less wear and tear. They typically require less maintenance, resulting in lower servicing costs and longer-lasting components.

- Quiet and Smooth Operation: Electric motors are quieter and offer smoother acceleration than internal combustion engines. This contributes to a more comfortable and peaceful driving experience.

- Instant Torque: Electric motors deliver power instantly, providing quick acceleration and responsive performance, even at low speeds. This can make EVs feel sportier and more fun to drive.

- Regenerative Braking: EVs often incorporate regenerative braking systems that recover energy during deceleration and braking. This improves energy efficiency and can extend the vehicle's range.

- Energy Security: EVs can be charged using various energy sources, including renewable energy such as solar or wind power, reducing dependence on fossil fuels and enhancing energy security.

- Reduced Noise Pollution: The quiet operation of EVs helps reduce noise pollution in urban areas, contributing to a more peaceful environment.

How to made EC vehicle less price and more affordable? In my country this EV car cost twofold of a regular LCGC car.. Since my country packed with middle income citizens, still the EV Vehicle wouldn't be an option because of their high price

The cost of getting new cars such as EVs are most likely not in someone's budget. Also, the inconvenience of finding a charging port (most places don't have them), then waiting however long for your car to charge can be quite annoying, whereas pumping gas only takes a few minutes or so.

As efficient as EVs are, the amount of carbon emissions that go out of manufacturing EVs is still harmful to the atmosphere. Maybe there will come a time when manufacturing vehicles is eco-friendly.

EVs can cost way too much money, so it's practically impossible for people who have lower incomes to even buy an EV. Even if you do buy one, it's likely going to be near impossible to find a charging station for it or to charge it in neighborhoods where it's difficult to find parking.

Evs are very beneficial to the environment, they also make it very easy for the car owner to use and operate it. Along with all of these great things they also are very expensive so most people aren't able to afford it, they also are promoted towards people who have driveways and not all people have them.

Because there are fewer parts and less maintenance that comes with an Ev, this makes it more efficient for the user. If the price wasn't so unaffordable for the average person I think it could become a more common sight in today's streets.
