Why Electric Vehicles Are Designed the Way They Are

Think about an electric vehicle.

No engine noise.

Instant acceleration.

A dashboard that feels more like a screen than a control panel.

It looks familiar…

but it behaves completely differently.

In this episode of Curious by Design, we explore why electric vehicles are designed the way they are—and how removing the internal combustion engine reshaped the entire architecture of the car.

Traditional cars were built around one dominant component: the engine. It dictated layout, weight distribution, and how power moved through the vehicle. Electric vehicles flipped that model.

Batteries are spread across the floor.

Motors are compact and often placed near the wheels.

The result is a lower center of gravity, more interior space, and a completely different driving feel.

We’ll break down why EVs accelerate instantly, how regenerative braking turns motion back into energy, and why range—and charging—drive so many design decisions.

You’ll also see how software plays a central role. From battery management systems to over-the-air updates, modern EVs behave more like connected devices than traditional machines.

Because designing an electric vehicle isn’t just about replacing fuel with batteries.

It’s about rethinking the entire system—

from performance…

to efficiency…

to how drivers interact with the car itself.

The next time you see an electric vehicle glide silently past you, notice what’s really different.

Not just the power source—

but the design decisions underneath it…

reshaping what a car can be.

That’s Curious by Design.

Welcome to Curious by Design. I'm your host, Jason Hardwick. This is the show about how things get built and why they end up the way they do. We tend to think design is about logos, architecture, or how something looks. But in reality, design is about choices. It's about trade-offs. It's about the invisible decisions that shape businesses, cities, systems, and even our everyday lives. On this podcast, we explore the thinking behind the work, how we got here, what worked, what didn't. All starting from the same place. Curiosity. A way to understand what's working, what's broken, and how we might design things better. If you've ever found yourself asking, why did they do that? You're in the right place. This is Curious by Design. Think about a car for a second. The sound of an engine, the vibration under your feet, the smell of gasoline, stopping at a gas station, filling up, and driving away. It feels normal, like that's just how cars work. But here's something most people don't realize. Gasoline cars were not the original design. Electric vehicles came first. In the early eighteen hundreds, long before highways, long before traffic lights, long before modern cities, engineers were already experimenting with electric propulsion. By the eighteen thirties, early electric carriages existed. They were slow, primitive, but they worked. By the late 1800s, electric vehicles had evolved significantly. In fact, around the year 1900, electric vehicles made up roughly one third of all vehicles in the United States. That's not experimental, that's mainstream. Electric cars had real advantages. They were quiet, smooth, easy to operate. No gears, no engine noise, and most importantly, no hand cranking. Gasoline cars at the time required a hand crank to start. A metal handle inserted into the engine, manually turned, often violently kicking back. People broke wrists, arms, sometimes worse. Electric cars avoided all of that. You got in and you drove. So for a brief moment in history, electric vehicles looked like the future. But they didn't win. The reason wasn't simple, and it wasn't just technology. It was systems, infrastructure, economics, and timing. Gasoline had one major advantage energy density. A gallon of gasoline contains far more usable energy than early batteries, which meant range. Gas cars could travel much farther without stopping. Then came a major turning point. In 1908, Ford Model T was introduced by Henry Ford. Ford didn't invent the car, he redesigned how cars were built. Assembly lines, standardization, mass production. By nineteen thirteen, Ford reduced production time from over twelve hours to about ninety minutes per car. That changed everything. Cars became affordable, accessible, scalable, and those cars were gasoline powered. Then another key innovation appeared. In nineteen twelve, Charles Kettering introduced the electric starter. This eliminated hand cranking entirely. Gas cars became easy to start, safe to use, practical. At the same time, oil infrastructure expanded rapidly. Drilling operations scaled, refineries improved, gas stations appeared everywhere. Electric infrastructure did not. And this is the key insight. Technology didn't lose, the system did. Gasoline cars had range infrastructure and manufacturing scale. Electric cars had limited batteries, limited range, and limited charging access. And once that system tipped, it stayed tipped for nearly a century. Electric vehicles didn't disappear completely. They just went quiet. Throughout the twentieth century, engineers kept experimenting, mostly in the background. Then came the oil crises of the nineteen seventies. Fuel became uncertain, prices surged, supply was unstable. Suddenly, electric vehicles made sense again. But battery technology still wasn't ready. In the nineteen nineties, another attempt emerged, the GM EV one, an early modern electric car. Aerodynamic, efficient, advanced, but it failed commercially. Range was limited, charging infrastructure barely existed, costs were high. So once again, electric vehicles faded. But something important had changed. Battery technology was improving, quietly, relentlessly, driven not by cars, but by electronics. Laptops, phones, portable devices. Lithium ion batteries improved energy density, longevity, recharge cycles. So when the moment came, the foundation was already built. The real shift happened in the early 2000s, not because of one invention, but because multiple systems aligned. Better batteries, better computing, better materials, and then a design shift. Tesla did something different. Instead of building a practical electric car, they built a desirable one. Fast, high performance, attractive. This wasn't just engineering, it was perception design. Electric vehicles were no longer slow, boring, limited. They became fast, modern, aspirational, and that changed adoption. Because people don't just buy transportation, they buy identity. Now let's break down how electric vehicles actually work. At a basic level, there are three core components a battery, an inverter, and a motor. The battery stores energy in direct current, DC. The inverter converts that energy into alternating current, AC. The motor uses that current to generate motion. But here's the key difference. Electric motors deliver instant torque. That means the moment you press the pedal, power is available immediately. No revving, no delay, no buildup. That's why electric vehicles feel fast, even at low speeds. Now here's something most people don't realize. Electric motors are incredibly simple. Compared to internal combustion engines, which can have hundreds of moving parts, electric motors have very few. Fewer parts means fewer failures, less maintenance, higher efficiency. Gas engines are about 20 to 30% efficient. Most of the energy becomes heat. Electric motors are often 85 to 90% efficient. That's not an improvement. That's a complete redesign. Now let's talk about one of the coolest features: regenerative braking. When you brake in a gas car, energy is lost, as heat. In an electric vehicle, the motor reverses, it becomes a generator, and sends energy back into the battery. You are literally recovering energy while slowing down. Now here's another thing most people don't realize. Electric vehicles don't actually have traditional transmissions. Most EVs use a single-speed gearbox. Because electric motors operate efficiently across a wide range of speeds, that eliminates gear shifts, complex transmissions, and mechanical losses. Now let's talk about design challenges. Batteries are heavy, very heavy. So engineers place them low, in the floor of the vehicle. This lowers the center of gravity, improves handling, increases stability, but it also changes the entire structure of the car. Electric vehicles are often built on what's called a skateboard platform, a flat battery base, with everything else built on top. This allows more interior space, better weight distribution, and improved safety design. Now charging, gasoline transfers energy quickly, charging does not. Even fast chargers take time, so the system shifts. Instead of refueling occasionally, you charge frequently. At home, at work, at stations, the behavior changes. Now here's a fascinating detail. Electric vehicles are often quieter, but that created a problem. At low speeds, they were too quiet. Pedestrians couldn't hear them. So regulations now require EVs to emit artificial sounds at low speeds. Even silence had to be redesigned. Now let's talk about the future. Electric vehicles are not just replacing gas cars, they are redefining transportation, software updates, over-the-air improvements, cars that evolve after purchase, energy integration, vehicles connected to homes, solar systems, power grids. Eventually, cars may store energy, distribute it, balance demand. The car becomes part of a larger system. And the biggest shift? Cars become less mechanical and more digital. Less about engines, more about systems. The same transformation we saw in phones, computers, everything. The next time you see an electric vehicle, pause for a moment and think about what it really is. Not just a car, but a system. A machine designed to rethink how motion works. And that is Curious by Design. Thanks for listening to Curious by Design. If something in this episode made you pause, rethink a decision, or see the world a little differently, that's the point. Design isn't just something we consume, it's something we participate in every day, whether we realize it or not.
