5 Reasons Why Petrol Engines Have No Future In Cars

14w ago


1. "The perfect car doesn't exist"

Different car reviewers have boasted that the perfect car doesn't exist, as no car can be both fast, economical, and practical, as compromises would always be made. While, for example, an Audi RS6 is both fast and practical, it suffers on economy. However, with the introduction of electric cars, such as a Tesla Model S and X, a car can have supercar acceleration, excellent storage capability and unbeatable efficiency. More on efficiency later.

2. Performance

This is something that should please the enthusiast. Since electric engines almost always deliver maximal power, it doesn't need gears. Therefore, acceleration is instant, and with the new Tesla Roadster coming along, electric cars will also be able to reach hypercar top speeds. Electric cars has already proven themselves at the traffic lights, where a Model S is one of fastest accelerating cars in the world.

3. Efficiency

First of all, let me introduce the term MPGe. This is the equivalent of how fuel efficient an electric car is, and is done by calculating how many miles an EV gets on the energy equivalent of a gallon of petrol. The new Tesla Model 3 Standard Range Plus, the cheapest Tesla on sale today, is rated at 134 MPGe. The battery on the long range Model 3 has a capacity of roughly 7,5 liters of petrol, but it is rated to being able to travel 560 km, verified by the new WLTP standards. And why is it this efficient, while boasting supercar performance, you might ask? Well, the drivetrain is one of the main reasons.

4. Electric Engines VS Petrol Engines

The electric engine is an amazing drivetrain for cars, especially now, when battery technology has come a far way. The problem with petrol engines is that the energy lost to heat is astonishing. Even the best petrol engines struggle with 50 % efficiency, when electric engines hovers around the 90 % mark. This high efficiency is mostly because of the fact, that the engine only has one moving part, and doesn't require combustion inside the engine to work.

Also, because an electric engine doesn't require air to run, the drag coefficient of the car is much lower, causing the car to cut much more efficiently through the air. For example, a Tesla Model 3 has a drag coefficient of 0.23, while a comparable petrol car, a F30 BMW 3 series, has a drag coefficient of 0.30.

Also, because electric engines doesn't breathe air, and are more mechanically simple, servicing them is much simpler, and doesn't need to be done as often. There is no need for new air filters and oil, as it is simply not required.

5. Onboard Tech

Another interesting aspect of electric cars, is the technology onboard the car. A Tesla can drive itself, park itself and even be summoned. While lane assist and adaptive cruise control does exist on fossil powered cars, and have for some time now, electric cars seem to be more innovative and modern in as many ways as possible. A good example of this, is Tesla's, which can update themselves. Other cars would normally require a trip to the dealer to get software upgrades, but that isn't necessary on a Tesla.

  • 1. Electric isn’t the future, hydrogen is. Lithium mining is just as bad for the environment as oil drilling. 2. You seem to imply that electric cars can be “perfect” but fail to mention that when switching to electric, you lose the customizability and most of the emotion of the car. You can’t put twin turbos and a titanium performance exhaust on an electric car, you just get on your computer and turn up the power. It’s less personal than gasoline.

    • Hydrogen has no future in transport. Efficiency is terrible so will always cost more on a pre mile basis.

      Lithium mining is nowhere near as bad a drilling for oil. I don’t know...

    • Once hydrogen is tested and refined, it’ll be just as practical as electricity. The Toyota Mirai has 66 mpg, while the comparable Prius only gets up to 58 mpg. Also, mining vs....

  • is correct- mining for batteries is a filthy business, raw materials have catastrophic environmental effects. The materials are shipped around the world ( using diesel) to be made into batteries in a factory that isn’t eco-friendly, them batteries are shipped to a car factory, then the whole thing gets shipped here. Then you recharge it using electricity from a non eco-source all to go a little quicker off the line? Ridiculous.

    You’ve traded one exhaustible commodity for another.

    Hydrogen is infinite- the whole galaxy is made of it. Hydrogen cars have been available for a long time- Korea and china have figured it out.

    Hydrogen combined with ICE or electric is the future

    Exclusively electric is limited- it takes too long to refill & range is always going to be limited.

    Let’s not forget either, that batteries don’t have a good shelf life. The reason you don’t see any mark 1 Prius on the road is that batteries die. They cost a fortune to replace so cars get scrapped. What happens to all those dead battery packs? They go back to destroying the environment.

    • Lithium extraction is a lot cleaner than oil drilling, and doesn’t cause earthquakes.

      Also there is plenty of lithium. So much so that it’s abundance is measured in a percentage...
