Hey everyone, DennisCW here! The Tesla Model Y Performance just launched, and while there haven't been official range tests yet, I've already put over 200 miles on mine without the wheel caps (those aero covers that help efficiency). Spoiler: it's the most inefficient Tesla out there right now—especially with the 21" wheels for that sporty look. But let's dive into the real numbers and see what this means for you.
If you're eyeing the Model Y Performance, efficiency probably isn't your top priority. You're here for the blistering acceleration, plush comfort, and track-ready performance. Speaking of which, I'm taking this beast to Tesla Corsa—a Tesla enthusiasts' track day on February 28th. Check the link below and use promo code DENNIS to save some cash!
Since my last full charge:
What does that mean? Lower Wh/mi is better (more efficient). My driving style? A mix of Chill and Insane modes, but I've been easy on the throttle to preserve the tires.

For context:
With my no-caps, 21" wheel setup at 258.6 Wh/mi, full range estimate: 310-315 miles (100% to 0%). But real-world? Tesla owners rarely drain to zero—we top up at home or Superchargers. Using 80% of the battery, expect solid daily usability.

Total ownership stats so far:
| Vehicle | Avg Efficiency (Wh/mi) | |----------------------|------------------------| | Model Y Premium | 210-220 | | Model Y Performance | 258-264 | | Cybertruck | 450-550 |
The Performance model is 10-20% less efficient than the standard Y, but it's way better than my Cybertruck. And honestly? With a home charger, range anxiety is a non-issue. Just plug in when you get home.
Want better efficiency?
Efficiency be damned—this thing is built for fun. Can't wait to push it at Tesla Corsa. Join me if you're in! [Link and promo code DENNIS below.]
At the end of the day, the Model Y Performance delivers thrills over MPG equivalents. If performance isn't your jam, stick with the standard model. What do you think—worth the efficiency hit? Drop a comment!
Stay charged, DennisCW
