David Blenkle is running the kind of mileage that usually ends arguments, not cars. The Santa Cruz, California, private-car-service driver has pushed his 2022 Ford Mustang Mach-E past 300,000 miles, turning a modern EV into a real-world durability test. What makes the story stand out is not just the odometer but also the reported battery health after nonstop commercial-style use. In a world still full of battery-anxiety takes, this Mach-E is a rolling case study in what high-mileage EV ownership can actually look like.
Blenkle runs a small private car service in Santa Cruz, California, and his 2022 Ford Mustang Mach-E has now crossed 300,000 miles, with more than 316,000 miles reported in recent coverage. The headline is not just the odometer. It’s the battery health. Forbes says he’s seen only about 8% battery degradation despite that mileage, a figure that would have sounded optimistic to most EV skeptics a few years ago.
This isn’t a garage-queen EV story either. Blenkle’s Mach-E has been working for a living, piling on highway miles day after day. Ford previously highlighted his car when it had already passed the 250,000-mile mark, framing it as a durability case study for the Mach-E’s battery and powertrain under high utilization.
The Part Everyone Cares About: Battery Degradation
The common fear with EVs has always been the battery turning into a giant depreciation bill. Real-world high-mileage stories like this are starting to push back on that narrative.
InsideEVs previously reported that at around 250,000 miles, Blenkle said he was still seeing about 290 miles of range from a vehicle that was EPA-rated at 303 miles when new, implying roughly 4% degradation at that point.
Forbes’ newer update pushes the story further, stating the Mach-E has surpassed 316,000 miles with only an 8% loss. Even if you treat that as an approximate figure rather than a lab-measured test, the broad point stands. This is not the “needs a battery at 100k” scenario that a lot of people still assume.
Why His Mach-E Is Holding Up
High-mileage outcomes in EVs usually come down to a few factors: usage pattern, charging habits, and thermal management. Blenkle’s work profile likely helps. Private car service miles tend to be steady, highway-heavy, and predictable, which is generally easier on drivetrains than constant short trips.
The Mach-E also benefits from modern battery management and active thermal control. While every EV is different, there’s a growing body of owner data suggesting degradation is often single-digit for a long time when the car is charged and driven normally.
The Warranty Question People Will Ask Next
Ford’s high-voltage battery warranty is a key part of the Mach-E ownership equation, but stories like this shift the conversation beyond “will it last through the warranty” and into “how long can it realistically go?”
In other words, the battery durability discussion is slowly starting to look more like the durability discussion we already have for engines and transmissions. Some units will be outliers in the wrong direction, but high-mileage outliers in the right direction matter too, because they show what is possible under heavy real-world use.
What This Means for Used EV Shoppers
For buyers watching EV depreciation and thinking about the used market, this is the kind of story that reduces perceived risk. A three-year-old EV with 30,000 miles is one thing. A three-year-old EV with 300,000-plus miles still functioning with modest range loss is another. It reframes what “high mileage” even means in an EV context.
It also supports a broader trend: as more high-mileage EVs accumulate real-world data, the market will get better at pricing used EVs based on evidence, not fear. That matters for everyone, not just Mach-E fans.
The Guessing Headlights Take
The most interesting part of Blenkle’s Mach-E story is that it’s not flashy. It’s repetitive, boring, and consistent, which is exactly what durability looks like.
If an EV can rack up over 300,000 miles in commercial-style use with single-digit battery degradation, the conversation shifts. It becomes less about “will the battery fail” and more about what really drives long-term ownership costs: tires, suspension wear, software updates, charging convenience, and how the car fits your life.
Battery anxiety is not gone. But it’s getting harder to justify as a blanket argument when the odometer keeps climbing and the range drop stays modest.
