When a new sports car claims a “2.5-second run to 60 mph,” you don’t need more details—you already know it’s brutally quick.
When you see a new sports car rated at “0–60 in 2.5 seconds,” you instantly know—it’s a monster. This metric has become so ingrained that few people stop to ask: why 60 miles per hour? Why not 40, or 90? How did this number become the universal language spoken by automakers, journalists, and enthusiasts alike?
To answer that, you have to go back to postwar America—the early days of automotive journalism—and to a man often considered the grandfather of modern car reviews: Tom McCahill.
Before the mid-1940s, the idea of an independent road test barely existed. Automakers stuck to a simple, convenient stance: we test our own cars—we don’t need outside opinions. Journalists mostly rewrote press releases.
That changed thanks to McCahill. A bankrupt garage owner turned freelance writer, he faced a basic problem: how do you test cars if manufacturers won’t give you any?
He got creative.
In 1946, posing as a photographer, McCahill convinced a rail yard worker to unload a brand-new Buick straight from a freight car so he could “take pictures.” The result wasn’t just photos—it became a full road test published in Mechanix Illustrated, widely considered the first true independent car review.
Automakers quickly realized resistance was pointless. McCahill had opened Pandora’s box. Soon, manufacturers were officially supplying him with cars—and a new testing standard was born. Among the data he consistently reported was one simple figure: acceleration from 0 to 60 mph.
McCahill never left a clear explanation for choosing 60 mph before his death in 1998. But automotive historians generally point to two main reasons.
The first is practical. In the late 1940s and early 1950s, highway speed limits in the U.S. hovered around 50–60 mph (with 60 mph becoming more standardized by the early ’50s). For everyday drivers, 60 mph wasn’t abstract—it was real-world driving speed. Measuring 0–60 showed how quickly a car could merge into highway traffic.
The second is more coincidental. Sixty miles per hour is roughly 96.6 km/h—close to 100 km/h. While McCahill likely didn’t care about the metric system, that near equivalence helped the standard go global.
As European and Asian automakers adopted American-style testing, they simply rounded up. That’s how 0–60 mph evolved into 0–100 km/h. To this day, some engineers—especially in the UK—prefer quoting 0–62 mph to match the metric equivalent more precisely.
Originally, 0–60 mph was a straightforward reflection of engineering—engine power, gearing, traction. But over time, it took on a life of its own.
Automakers began optimizing specifically for that number, sometimes using techniques that blur the line between testing and marketing. One example is “rollout”—borrowed from drag racing—where the timer starts after the car has already moved about a foot. That alone can shave off 0.2–0.3 seconds, which matters a lot in headline figures.
Experienced testers, including teams at Car and Driver, introduced alternative metrics like 5–60 mph. This measures real-world acceleration without launch tricks, showing how responsive a car feels in everyday driving rather than how hard it can launch off the line.
Today, the industry is facing something like “0–60 inflation.”
Twenty years ago, hitting 0–60 in under five seconds was supercar territory. Now, even family EV crossovers can outperform early-2000s exotics at a stoplight. When something like the Zeekr 001 FR can out-accelerate legends like the McLaren F1, it raises a fair question: does this number still tell us much?
Manufacturers are now approaching physical limits. Take the latest Chevrolet Corvette ZR1—in hybrid form, it has dipped into the sub-2-second range to 60 mph. At that level, cars are accelerating faster than objects fall under gravity. Chasing tenths—or even hundredths—becomes increasingly irrelevant for everyday drivers.
And yet, 0–60 mph isn’t going anywhere.
It has become the automotive world’s version of Esperanto—a simple, universally understood benchmark that lets us compare cars across decades, segments, and technologies.
More than just a number, it’s a symbol. Thanks to one inventive American journalist, it has spent nearly 80 years giving drivers, fans, and engineers a common way to talk about what matters most: the raw, visceral thrill of acceleration.
And as long as people keep arguing about cars—especially online—that number isn’t losing relevance anytime soon.
