FSD v14 Drove 75% of My Miles Last Year. Here's the Rest of What I Learned.
Since switching to FSD v14, the system has handled about 75% of the 13,000 miles I've put on the car. That number surprised me. Not because FSD suddenly became perfect, but because 75% means I'm actually using it consistently instead of toggling it off every time I hit a construction zone or a tricky merge. v14 changed my behavior more than it changed the car.
The Efficiency Reality
Over 16,063 lifetime miles, my Model Y is averaging 260.1 Wh/mi (3.84 mi/kWh). That's... fine. Respectable. Not the number Tesla's marketing would have you frame on a wall, but real-world efficiency rarely is. And that average includes highway, city, summer, winter, and the occasional lead-footed moment.
What's not consistent is winter. A 40-mile round-trip in the cold chewed through 120 miles of indicated range. That's a 3x ratio between miles driven and range consumed. If you live somewhere with real winters and you're planning around EPA numbers, stop that.
What It Actually Cost to Own
Annual service came out to $67.41. A tire rotation ($65), windshield washer fluid ($2.41), and one free front camera housing cleaning. That's it. One year, over 13,000 miles, $67 in maintenance. Compared to oil changes alone on my last car, I'm ahead before I count fuel savings.
The Tesla app's Charge Stats put fuel savings at $836 over one year. But here's where I'd push back on my own numbers: I relied primarily on Superchargers instead of home charging for a chunk of that time. If I'd had home charging from day one, the estimate is closer to $1,500 in savings. Superchargers are convenient, but they're not $0.10/kWh from your outlet at midnight.
What's New on the 2026
The 2026 Model Y isn't the same car reviewed endlessly for the past three years. The acoustic-lined glass on the Premium actually works. Road noise at highway speed is noticeably reduced. Not whisper-quiet, but a real improvement over earlier versions.
Grok is now integrated for cabin temperature control and headlight control. Asking an AI chatbot to turn on your headlights is a little absurd in concept, but if it works reliably it's also just fine. The Model Y L has a noticeably larger rear windshield compared to the standard version, which improves rear visibility in a way I didn't expect to care about as much as I do. And the vegan leather seats now include ventilation. Wireless charging mat is still standard. Software version 2026.26.6.5 is what's running on mine.
FSD v14, Specifically
I've been running v14.3.7 and v14.3.8. The driving style options now include Hurry Mode, which is exactly what it sounds like. More aggressive lane changes, less patient at intersections. Whether you want that depends entirely on where you drive.
But the 75% figure is the real story. FSD used to be something I'd engage, watch fail, and disengage. Now it's something I turn on and mostly just verify. That's the actual change in v14: not perfection, but enough consistency that I trust it with routine miles.
The Safety Number
The Model Y holds an IIHS Top Safety Pick+ rating. Worth knowing if you're buying. Doesn't change much in daily driving, but it belongs in any honest ownership summary.
One Year In
$67 in service. $836 in fuel savings (closer to $1,500 with home charging from day one). 3.84 mi/kWh over 16,000 miles. FSD handling 75% of miles since v14. The 2026 Model Y is a better car than what I originally tested, the economics work even leaning on Superchargers, and the winter range hit is real but survivable once you plan for it.
The spreadsheet mostly held up. That's not a small thing.
