There are so many reasons why electric vehicles (EV) will soon take over and petrol and diesel cars will be consigned to the dustheap of history.
Your average ICE (Internal Combustion Engine) vehicle has over 2000 moving parts and needs regular maintenance, tuning, fluid replacement, and part replacement. Your average EV has fewer than 200 moving parts. The only fluid that needs replacement is windshield washer. It needs no regular maintenance except for tire-rotation.
Petrol is an energy-dense material but unfortunately, when it’s burned, less than 30% of that energy is converted to propulsion. The rest is lost as heat and waste gases, including carbon monoxide and other pollutants. In an EV, over 80% of the energy is converted to propulsion and there’s no exhaust whatsoever. So even though batteries are less dense for energy storage, EVs are far more efficient.
And LiIon batteries are still fairly young in their development cycle, with small but significant improvements happening every year. (Not to mention all the research happening into new battery technologies.) IC engines are effectively at the end of their development cycle; there’s almost no further efficiencies or optimizations possible.
Some people complain about battery charging times. But as the owner of an EV, I’ve found that never to be a problem. For daily driving, I charge at home, in the middle of the night when electricity costs almost nothing. For long distance trips, I can charge on the road in about 15–20 minutes (time for a stretch, bathroom break, coffee and snacks) or at my destination (thousands of hotels are installing chargers, or on any 110V or 240V outlet.) And charging times are rapidly decreasing; Tesla’s current superchargers operate at around 150kW but many manufacturers and 3rd party charging companies are planning chargers that will operate at 300kW or more. New battery technologies also have the potential to allow faster charging times.
EVs are also way more fun to drive, with virtually instantaneous acceleration and torque, regenerative braking, better cornering due to a lower center of gravity, way more storage space (no gas tank, smaller motors, batteries in a “skateboard” across the bottom of the car, no central tunnel down the middle of the passenger compartment), etc.
Finally, ICE vehicles will disappear because they are significant generators of pollution and global warming. Dozens of countries around the world are planning and enacting laws to block the sale of new ICE vehicles completely in the next 15–20 years, for all the reasons mentioned above. And it’s not just cars; buses, smaller trucks, large semi-tractor trailers, and even construction vehicles are all moving towards electrification. Removing millions of ICE vehicles from the roads will take decades but we’ll end up with a cleaner, safer world.
