Elon Musk didn't start Tesla. Most people think he did, but he didn't. He was an early investor who eventually took the reins, but the seeds were planted by Martin Eberhard and Marc Tarpenning. This matters because if you want to understand the electric car maker since 2003, you have to look at the scrappy, Silicon Valley origins that had nothing to do with Detroit and everything to do with proving that lithium-ion batteries weren't just for laptops.
It started in San Carlos.
Two guys wanted to build a car that didn't suck. Back then, "electric vehicle" meant a glorified golf cart or the GM EV1, which had been famously crushed in a graveyard of corporate hesitation. Tesla Motors was incorporated in July 2003. They weren't trying to save the planet at first—at least not primarily. They were trying to build a high-performance sports car that happened to be electric.
The Brutal Reality of Being an Electric Car Maker Since 2003
Building cars is hard. Building electric cars from scratch in 2003 was borderline suicidal.
The industry was skeptical. No, that's too soft. The industry was hostile.
For the first few years, the company was basically a science experiment with a massive burn rate. When they finally showed off the Roadster prototype in 2006, the world saw a Lotus Elise body stuffed with thousands of cylindrical battery cells. It was brilliant and terrifyingly expensive.
Why the Roadster changed everything
People forget that the Roadster was the proof of concept. It showed that an EV could be sexy. It could be fast. Most importantly, it could go more than 200 miles on a single charge.

The struggle was real, though.
By 2008, Tesla was weeks away from bankruptcy. Musk had to pour his last $40 million—everything he had left from the PayPal sale—into the company to keep the lights on. It was a "hail mary" pass that actually connected. Since then, the trajectory hasn't been a straight line up; it’s been a jagged, chaotic climb.
The Model S and the Pivot to Mass Production
If the Roadster put them on the map, the Model S redefined the map entirely. Launched in 2012, this was the moment Tesla stopped being a niche toy maker for tech bros and started being a legitimate threat to German luxury brands.
Think about the interior.
That massive 17-inch touchscreen? It looked like a spaceship compared to the button-heavy dashboards of Mercedes and BMW. It wasn't just about the drive; it was about the software. Tesla realized early on that an electric car maker since 2003 needed to act like a software company, not a metal-stamping plant. Over-the-air updates meant your car could actually get better while it sat in your garage overnight.
The Gigafactory Gamble
You can't talk about Tesla without talking about batteries. They realized early that the world's battery supply was nowhere near enough for their ambitions.
So they built their own.
The first Gigafactory in Nevada was a massive risk. It was an "all-in" bet on the idea that scale would drive down costs. They were right. The price of lithium-ion battery packs has dropped over 80% since 2010, and Tesla’s vertical integration is a huge reason why. They don't just buy parts; they build the machines that build the parts.
The Model 3 and "Production Hell"
2017 to 2019 was a dark time. Musk famously called it "production hell."
The Model 3 was supposed to be the car for the masses, but the assembly lines were a mess. They tried to automate too much, too fast. Robots were tripping over each other.

At one point, they had to build a giant tent in the parking lot of their Fremont factory just to house an extra assembly line. It looked desperate because it was. Honestly, most companies would have folded under that kind of operational pressure. But they pushed through, and the Model 3 became the best-selling electric car in history for a significant stretch.
Engineering Culture vs. Traditional Manufacturing
Traditional car companies like Ford or Toyota prioritize "six sigma" perfection and slow, steady iterations. Tesla is the opposite.
They break things. They ship "beta" software to customers (looking at you, Full Self-Driving). They change the hardware in the middle of a production year without waiting for a "new model year."
This drives traditionalists crazy.
- Software-First: The car is a computer on wheels.
- Supercharger Network: While other makers waited for third parties to build chargers, Tesla built their own walled garden. It’s arguably their biggest competitive advantage today.
- No Dealers: They sell directly to you. No middleman, no "let me talk to my manager" nonsense.
The Autopilot Controversy
We have to talk about the elephant in the room. Tesla’s branding of "Autopilot" and "Full Self-Driving" (FSD) has been a lightning rod for criticism. Regulators are constantly breathing down their necks.
Is it actually self-driving? No. Not yet.
It’s a sophisticated Level 2 driver-assist system. But because they've been an electric car maker since 2003 with millions of cars on the road, they have a data advantage that no one else can touch. Every mile driven by a Tesla owner feeds back into their neural networks.
What the Competition is Finally Doing
For a decade, Tesla was basically the only game in town if you wanted a long-range EV. That’s over.
Hyundai and Kia are killing it with the Ioniq 5 and EV6. Porsche’s Taycan is a masterpiece of engineering. Even the Chinese giants like BYD are now outperforming Tesla in certain markets. The "Tesla Killer" isn't a single car; it's the fact that the entire industry finally woke up.
But Tesla still has the margins. They make more profit per vehicle than almost any other high-volume manufacturer. They’ve turned car-making into a commodity business while keeping luxury-tier brand loyalty.
The Real Legacy of Tesla
Whether you love Elon Musk or can't stand his Twitter (X) feed, you can't deny the impact. Before Tesla, the electric car was a joke. It was a punishment.
Now? Every major manufacturer has committed to going fully electric in the next decade or two. That doesn't happen without the pressure from a tiny startup that refused to die in 2008.
They've forced the world to care about:
- Battery density and chemistry.
- Charging infrastructure.
- The viability of heat pumps in cold weather.
- Giga-casting (using massive single-piece molds for the car frame).
How to Navigate the EV Market Today
If you're looking at an electric car maker since 2003 for your next purchase, don't just look at the 0-60 times. Look at the ecosystem.
Buying an EV is about more than the car; it's about the "fueling" experience. Tesla’s Supercharger network is still the gold standard for road trips. However, the gap is closing as other brands gain access to the North American Charging Standard (NACS).
Practical Steps for Potential Owners
Check your home wiring first. Most people think they need a massive upgrade, but a simple 240V outlet (like for a clothes dryer) is usually enough for overnight charging.
Download the PlugShare app. It’ll show you exactly how many non-Tesla chargers are in your area. You might be surprised.
Don't buy for the "future" software promises. If you're buying a car today, buy it based on what it can do now. If the current range and the current tech suit your lifestyle, great. If you're waiting for "Level 5 autonomy" to sleep in the back seat, you’re going to be waiting a while.
Test drive the competition. The "Tesla experience" is unique—minimalist, screen-heavy, and fast. But some people hate the lack of physical buttons. Try a Mustang Mach-E or a BMW i4 just to see the difference in cabin philosophy.
Tesla changed the world, but the world has caught up. The choice is finally yours.

Key Action Items for EV Buyers
- Audit your commute: If you drive less than 40 miles a day, even the most basic EV will work for you without needing a fast charger at home.
- Investigate Incentives: State and federal tax credits change constantly. Check the current IRS guidelines for the Clean Vehicle Credit before you sign anything.
- Understand Battery Degrade: It's a real thing, but it's slower than you think. Most modern EV batteries will outlast the car's chassis.
- Check NACS Compatibility: If you're buying a non-Tesla, make sure it comes with (or has an adapter for) the Tesla Supercharger network. This is the new industry standard.
Tesla remains the dominant electric car maker since 2003, but the next decade won't be as lonely for them as the last two were. The real winners are the drivers who finally have options that don't involve a gas pump.
