I’ve always loved going fast—planes, motorcycles, the roar of a V8. But over time, I started asking a simple question: what does all that speed actually cost? Not in dollars, but in fuel, efficiency, and sanity. This isn’t about guilt. It’s about curiosity, real-world numbers, and why sometimes the slow lane is the smarter move.
- Speed is satisfying—but expensive. Driving faster can burn up to 20% more fuel with barely any time saved.
- Modern cars are smarter than we think. With better habits, your gas car might beat cruise control and sip fuel like a hybrid.
- Slowing down doesn’t mean giving up. It could mean less stress, less noise, and more time to enjoy the drive.
Yes, I Love Speed. But I Also Love Fuel Efficiency.
Let me start by saying this: I love speed.
I’m into planes, motorcycles, fast cars—anything that moves fast and makes noise. I’ve worked in aviation. I’ve had my foot to the floor on the German Autobahn, and it was great. One of my go-to phrases used to be, “Let’s go burn some dinosaurs,” because honestly, there’s something undeniably fun about machines that go fast and burn fuel doing it.
I also grew up appreciating old-school horsepower. One of my all-time favorite cars is the 1969 Z28 Camaro. My uncle had one when he was younger, and according to my dad, you could actually watch the gas gauge drop in real time when you stepped on it. That car was probably getting five miles per gallon when it was under load, and it was set up for drag racing. It wasn’t built for fuel economy—it was built for one thing: going fast in a straight line and sounding great while doing it.
So, yes—I fully admit I’m a bit of a hypocrite. I’ve always loved power. But I’ve also always been curious about how things work, and over time, that curiosity shifted toward how to make things work better. More efficiently. Especially when I bought my first modern car. It wasn’t anything exotic, just a solid, turbocharged four-door with 150 horsepower. But what caught me off guard was how good the fuel consumption was—especially driving around Poland’s country roads.
That’s when I started thinking: “What’s my car’s sweet spot? How fast can I go and still win on fuel?” And from there, it became something I couldn’t stop noticing.
The Autobahn Wake-Up Call
Now obviously, once you get on the highway, your fuel economy takes a hit. That’s expected. But when I got on the German Autobahn and had the chance to let loose legally—no speed limit, foot to the floor—I realized something I hadn’t truly felt before.
I was using fuel at a rate that didn’t just feel excessive, it felt… inefficient to the point of being ridiculous. The car wasn’t just working harder—it was working like hell. Turbo whining, RPMs high, engine fully engaged in giving me that last few kilometers per hour. And it got me thinking: how much am I actually paying, in fuel, just to go this fast?
I wasn’t even trying to be frugal that day. I just wanted to see what the car could do. But that moment, flying along at top speed, got me curious. What does the curve look like between speed and fuel use? Is it gradual, or is there a steep cliff where the fuel economy just falls apart?
That one drive flipped a switch in my head. Suddenly I wanted to understand the physics behind it. I started wondering where my car hits its aerodynamic wall—at what speed air resistance starts taking real chunks out of efficiency. I imagined plotting it all out on a graph: speed vs. fuel consumption. Where’s the cliff? What’s the tradeoff?
It wasn’t just about numbers. It was about this nagging realization: here I am, driving a well-designed, efficient modern car… and I’m completely canceling out all that efficiency just by being in a rush.
That was the wake-up call. Not because I suddenly turned into a hypermiling eco-hero, but because once I saw it for myself, I couldn’t unsee it. And the next time I drove the same highway, I found myself backing off the gas just a little—curious to see if the ride could be quieter, smoother… and a little less thirsty.
The Fuel Game: Beating Cruise Control
At some point, I turned fuel economy into a personal challenge.
It started out casually—I drive a manual, so I’ve always been more engaged in what the car’s doing. You notice things when you’re shifting gears yourself. You start to pick up on the rhythm of the road, the feel of the incline, how much you need to lean into the throttle to maintain speed. And before you know it, you’re not just driving—you’re strategizing.
I found myself paying more and more attention to the real-time fuel consumption display in the car. I’d try to coast when I could. I started watching the terrain like a hawk—if I saw a hill coming, I’d figure out the best gear and the right RPM to hold. The little on-screen prompts telling me to shift up or down? I started ignoring them. They’re blind to elevation, and frankly, half the time they want you in a gear that makes no sense for the grade you’re on. I trust my legs and ears more than a dashboard icon.
At some point, it became a game: can I beat my cruise control?
Cruise is efficient—but it’s also predictable. It doesn’t anticipate a hill or know when a gentle roll can carry you further than expected. So I started competing with it, trying to outsmart it manually. And I did. My best result? 3.5 liters per 100 kilometers. That’s about 67 miles per gallon (US) or 81 MPG (UK). Not in a hybrid, not in a Prius, but in a full-sized, turbocharged gasoline car. Just by paying attention.
I think this whole thing really started back in my 1984 Chevrolet Caprice. It had a basic analog fuel economy gauge—probably running off a vacuum tube or something. No tachometer, but I had this little needle that would move as I applied throttle. I’d sit there in neutral and tap the gas just to watch it swing. That’s when I started realizing you could see fuel waste, not just feel it at the pump.
These days, if I’m driving down from a mountain pass—like from Lake Tahoe to Sacramento—I’ll throw it in neutral and coast the whole way down. I know I burned extra gas getting to the top, so now I’m reclaiming what I can. And honestly, it feels like a win.
How Much Are We Really Paying for Speed?
We talk about fuel costs like they’re just part of driving. But once I started paying attention, I realized something a little absurd: we’re spending noticeably more fuel—sometimes 15 to 20 percent more—just to shave a couple of minutes off a trip.
Let’s say you’re doing 70 miles per hour instead of 60. On a 30-minute commute, you’ll get there maybe 3 or 4 minutes faster. But your fuel economy tanks. The U.S. Department of Energy says that for every 5 MPH you drive over 50, it’s like paying an extra 18 to 24 cents per gallon. And in a lot of cars, that number stacks fast. You’re not just burning more gas—you’re canceling out the design of your car’s engine, aerodynamics, and all the fancy fuel-saving tech it comes with.
It’s funny how “time is money” has become this unquestioned truth. But in this case, the math’s backwards. You’re spending money to save time, sure—but you’re also throwing away fuel efficiency, increasing noise pollution, and, in a lot of cases, just adding stress. I’ve been in the fast lane. I still like it sometimes. But if I’m not in a rush, I’ll gladly slide into the slow lane and let the rest of the world tear past me.
And let’s talk about noise, because that’s a cost most people completely ignore. Cars aren’t just loud because of the engine. At higher speeds, it’s the tires, the pavement, and the wind resistance creating this constant low roar. Ever tried to sleep at a campground next to a highway? It’s not just trucks downshifting or engine braking—it’s the persistent hum of everyone doing 70 or 80, 24 hours a day.
During COVID, when cities paused things like grass cutting, municipalities saved millions—millions—just in mower fuel. And you know what? The world didn’t fall apart. The wildflowers looked great. It’s wild how much money we’re burning just to maintain some illusion of perfection—or to get somewhere a little faster.
All of it begs the question: what exactly are we rushing for?
What If Slowing Down Was the New Cool?
Here’s a thought experiment: what if we all just… slowed down?
Not because of a mandate. Not because of a fine or a new law or some “green agenda.” Just because we wanted to waste less fuel. What if tomorrow, every driver decided that the fast lane wasn’t the flex it used to be—and the real cool move was sipping fuel like a master?
I’m not talking about a full-blown campaign or a government ad blitz. Just an organic shift. Something like a quiet resistance movement of people who realize their cars actually drive better at 60 than 75. People who discover they enjoy the drive more when the engine’s not screaming at 3,000 RPM. People who realize that getting somewhere three minutes later isn’t a crisis.
It’s already happening in my own way. Some mornings, when I’m not in a rush, I’ll hang out in the slow lane. Just let the car settle in, roll with the flow, watch my fuel numbers creep into “impressive” territory. In Poland, it’s not that unusual. The far-right lane is basically the chill lane. As long as you stay out of the middle lane when you’re going slow, no one really cares.
I know it sounds idealistic, but slowing down actually changes the whole experience. It’s quieter. It’s more relaxed. You can hear your podcast. Your hands unclench from the steering wheel. And the fuel savings? It adds up. Especially if you’re driving a lot.
Would people freak out if highway limits were set at 60 MPH? Probably. You’d see protests. You’d hear a lot of “this is government overreach!” and “I have places to be!” But if people did it by choice? If it became a kind of underground badge of honor to be the one not flooring it?
I mean, why not? Maybe we need a dashboard badge: “Sustainable Speed Mode Activated.” Just imagine how smug we could all be.
Fuel Burn vs. Horsepower Love
I get it. I really do. I still love a good supercar. I still light up when I hear a throaty V8 or see an aircraft powering down a runway. There’s something primal and satisfying about machines that were built to go fast, sound loud, and eat fuel like it’s their job.
That 1969 Z28 Camaro I mentioned earlier? It’s still a dream car. That sound, the raw feel, the way it could drink a tank of gas faster than you could finish a coffee—there’s something deeply human about loving that kind of power. I’m not here to shame it.
Back when I worked in aviation, we used to joke about “burning dinosaurs” all the time. Aviation engines are rated in terms of fuel burn per hour. That’s how we think about it—not miles per gallon, but how many gallons we’re going through per hour of operation. And when you’re flying a small aircraft with a big engine, that number can be pretty eye-watering.
But even in aviation, that conversation is changing. There’s more awareness now about the source of aviation fuel, about efficiency, and about how flight compares to driving in terms of fuel per distance. In some cases, depending on the aircraft and the route, the fuel consumption is starting to rival that of a car—especially when you consider you’re flying in a straight line instead of winding through traffic.
So yeah, I still admire powerful machines. I still smile when someone says “turbocharged” or fires up something with 500 horsepower. But I also ask different questions now. I start wondering what that machine’s sweet spot is. How efficient can it be, not in theory, but in the real world?
You can appreciate horsepower and still care about how it’s used. It’s not either/or. I still love speed. But I love a challenge too—and right now, the better challenge might be doing more with less.
Takeaways: Is Speed Worth the Cost?
So where does all this leave me?
I still love speed. That hasn’t changed. I still admire loud engines, fast machines, and anything that reminds me why I ever fell in love with driving or flying in the first place. But I can’t ignore what I’ve seen from behind the wheel. The fuel economy drops are real. The waste is obvious. And once you start noticing it, it’s kind of hard to go back.
I’m not here trying to start a revolution. I’m not campaigning for new laws or trying to ruin anyone’s fun. I just think maybe we’re missing something really simple. What if one of the best things we could do is… just back off the gas a bit?
Modern cars are engineered to be incredibly efficient. We just have to give them the conditions to shine. That doesn’t require new technology or a lifestyle overhaul—it just requires a different attitude toward speed.
So next time you’re heading out and you’re not in a rush, try the slow lane. Watch your fuel numbers. Play the game. See if you can beat your cruise control. Honestly, it’s more fun than it sounds.
And hey—if nothing else, you’ll have a better excuse for being a few minutes late.
Because really: is speed worth the cost?
