Electric Vehicles: The Future is Here

A nerdy engineer’s comparison of electric vehicles to gas-powered equivalents addresses commonly held misconceptions and provides an exciting glimpse at the future of passenger transport.

You’re standing in a car dealership eager to purchase a brand new vehicle. You’ve narrowed the search down to two options. Both cars look nearly identical. Same wheelbase, interior, seating, a stereo system, driving range, etc.

Vehicle B costs 60% less to operate, uses 77% less energy, requires less maintenance and trips to the dealership, and produces 78% fewer emissions than Vehicle A. Oh, and Vehicle B is objectively more fun to drive. Did I mention it can be refueled in your garage while you sleep? The only discernable difference between the vehicle options is the drive train – of the way the car is powered.

Pop quiz: Which car would you be interested in test-driving?

Of course, we’re talking about the benefits of electric vehicles (EVs) over their internal combustion engine (ICE) counterparts. And those statistics you just read aren’t hypothetical. These cost and emissions calculations are based on real-world averages in California today (2021). And California boasts some of the most expensive electricity rates in the country.

Sharing the Good News

Today’s growing menu of EVs makes it hard to resist proselytizing to the world, “Look at how much more sense this makes!” In fact, I’m sure my family and friends are tired of hearing the message.

Nonetheless, some mornings I’m tempted to go on the street corner with a megaphone shouting, “Look here! Put more money in your pocket, reduce reliance on foreign oil, and create cleaner air in your community!”

My fellow Americans – we need to talk. It’s 2021. This has gone on too long.

This is An IntEVention

Experts understand the concerns consumers bring with electric vehicles:

  • Range anxiety
  • Upfront costs
  • Lack of available models
  • Insufficient public charging infrastructure
  • Lack of general public awareness

It’s complicated, I know. On top of that, purchasing or leasing a new vehicle is a deeply emotional and personal experience. It’s a reflection of one’s sense of self, their being, their identity.

But I beseech you to look again. 2021 is already proving to be a pivotal year for EVs. Automakers are making commitments to make only EVs in droves. We’ve reached a tipping point.

Frankly, I feel an obligation to tout the benefits of EVs by sharing the facts; Facts that everyday drivers who enjoy money can’t (or shouldn’t) ignore.

Gas Fights

We’ve evolved well past the days of the limited-range EV nerd-mobile. A number of sleek-looking body styles are available in ranges exceeding 250+ miles. But the biggest benefit is efficiency.

As a mechanical engineer, the brazen inefficiencies of internal combustion engines for passenger transport often leave me wanting to bang my head against a wall. Especially when such viable alternatives currently exist on the market!

The U.S. Department of Energy (DOE) calculates only 19% of the gasoline in light-duty vehicle tanks powers the wheels. That statistic isn’t from the “land yacht” automobile era of the 1960s. We’re talking 2020.

That’s because internal combustion-powered cars waste 70% of the energy from every tank of gas through the tailpipe and radiator. It’s not your fault, it’s by design – it’s required to prevent engine overheating.

If that isn’t bad enough, we lose another 11% of the gas in your tank to drivetrain friction, parasitic loads, and auxiliary power. In summary,

Gas-powered cars waste 81% of the gasoline we purchase. That is insane.

Think about that for one second. Imagine filling up 20% of your tank at the gas station. Then, you take the remaining 80% of the gas you already pre-paid for a playfully innocent Zoolander-esque gasoline fight. That’s exactly what all of us are doing every single time we fill up (minus the gas fight).

Meanwhile, EVs approach 90% efficiency thanks to ultra-efficient motors and regenerative braking technology. Regenerative braking allows the vehicle to capture about half of the car’s moving energy during braking.

Where else in your life would you accept wasting 81% of your money?

Sticker Shock

“EVs cost too much.” Yes, I would agree. The average cost of a new car (not an EV) in the U.S. hit $40,000 in December 2020! That’s a lot of dough!

A handful of new EVs now fall under the $40k price point. Experts anticipate EV prices will decrease as manufacturers experience economies of scale from improved battery technology and manufacturing. For example, Tesla promises a $25k 4-door sedan by 2023.

Let’s briefly consider other cost variables in vehicle ownership.

Powering Up

A 2020 Consumer Report study found a typical EV owner who does most of their charging at home can expect to save an average of $800 to $1,000 a year on fuel costs over an equivalent gasoline-powered car. Another CR study found that owners of a 250-mile range EVs can cover 92% of their annual charging from home, requiring only six stops at a public charging station per year.

So what about maintenance? The study also found that maintenance end repair costs for EVs are significantly lower over the vehicle life—about half—than for gasoline-powered vehicles. No oil changes, fewer moving parts, simpler drivetrains. At only $0.03/mile, EV owners experience an average maintenance savings of $4,600 over the vehicle lifetime. We assume the owner will drive the national average of 13,000 miles annually.

Let’s recap the savings of an electric vehicle over a modest 10-year lifetime. Taking the low-end annual fuel savings estimate of $800 totals $8,000. Stack on $4,600 maintenance costs savings and badaboom badabang, and in ten years, that’s $12,600 of simple savings for an EV over a gas-guzzling equivalent.
