As the new owner of a "long range" Tesla I have been sorely disappointed by the road trip performance of the car. After reading so many glowing reviews (including MMM's and 1500 Days') I expected a good long-drive experience. I've taken it on two longer trips: 700 miles round trip a few weeks ago, and 400 miles today.
The usable range is 200 miles, and that's generous. This morning we drove 183 miles going from 80% charge to 13% charge, and the last 50 miles I reduced speed, nervous about range. If there were any hiccup - say, a crash that closed the freeway, or a fire that rerouted it, we'd have been stranded. A note: for battery longevity and reasonable charging speed, Tesla recommends not charging past 80% capacity except when strictly necessary. So claiming a 300 mile EPA range is from 100% to dead, and my ICE car will go 600 miles by the same criterion.
Everything else about the car is excellent. The charging speed is great, the software integration and charging infrastructure are excellent. The power is incredible, the handling good, it's a nice car.
The range is a very serious limitation. 200 miles "full" to "empty" is just a total nonstarter for many people across this country. And even when it's not prohibitive, it's significantly less safe than an ICE car in terms of being able to wait out bad weather, handle closed roads, evacuate during natural disasters, or other emergencies.
Another unpleasant surprise: the car is less economical to operate than a modern hybrid. A typical Tesla consumption is 275 wh/mi and so far I've been unable to supercharge at less than $0.46/kwh, giving about 12c/mi. A 45mpg hybrid at $4/gal is 8c/mi. So my Tesla costs fifty percent more more to drive in "fuel" than my $10,000 eleven year old Toyota. Disappointing.
These are early impressions and people who value acceleration and performance more than pure long distance performance will undoubtedly be far more enamored with these cars, but as a rigorously pragmatic Mustachian I am disappointed.
