Man do I love Hackernews. Everyone is pro-innovation, pro-future, pro-forward thinking until literally anything new happens, in which case everyone shows up with a "well, ackshually", to tell you why the new idea is dumb. It's amazing to me that Tesla continues to increase State Of The Art range and EV efficiency, at scale, for cars that already smoke the competition. I hope their fervor to improve the technology nev…

"Nobody is going to buy this thing. I commute 250 miles each way to my job, in my pickup truck. Call me back when Tesla makes a real car with real range. Anybody who buys these now is a sucker."

Because people keep saying shit like that. Tesla's range increases are a giant experiment to find out at exactly what point opposition to electric collapses.

This is impressive. Almost 650 Km. Conservatively, let's say 600 Km, it's very very impressive.

My daily commute is 30 KM, I can go 20 days without charging. Back of the napkin suggests that if I charge overnight in my garage, I can go without super charger charging for more than a month and a half. This is no small feat.

I've been following a multi-month discussion over in the r/electricvehicles subreddit about EPA range. There's a growing consensus that something is very wrong with it. Here are a couple of the articles that got some discussion in that sub: https://insideevs.com/news/407807/eletric-car-real-world-ran... https://www.caranddriver.com/reviews/a30874032/porsche-tayca...

My understanding is that the Taycan was seriously screwed by having its track modes, which are genuinely very inefficient, blended equally in to the test. It's a bit of a shame to see so many Tesla fans point to its supposed inefficiency based on the EPA range. It feels like the tables have turned 180 since the Top Gear scripted test days; it was shitty when Tesla was attacked with FUD back then and it's shitty when…

That’s really weird. Is it normal to blend in sport modes? Do you have a link to more info?

Can we have an EV for people who don't suffer from range anxiety and are willing to trade that off for cost?

I travel 5000km (3000mi) a year, longest single day use 50km (30mi). Vehicle is garaged with access to power. I just need 100km (60mi) (double to be sure :) ) range at an affordable cost.

So .. a used Nissan Leaf is good for you. 70-100 mile range. Probably < $12k

Not sure faking results counts as optimizing cars /shrug

They were not faked. Cars were optimized to behave in a certain way under exact test scenario. They were not producing any fake output data from the sensors, just "optimizing" engine behavior.

They didn't output fake data, true, but their "optimization" was to only activate emissions controls during testing. That's fraud.

Base model 3 is the car for you then.

Alrighty here's the first graph. Note that this is average speed, so any trips with an average speed near the right by definition have some parts of the trip faster than the average, so the actual drop at 80 mph isn't quite as severe as it looks. https://imgur.com/a/c10NXaz the reason for the cutoff is that because it's pretty hard to have a trip with an AVERAGE speed above 80mpg. It's very rare in my large dataset.

Cool! Thanks. Wonder what the jump from 31-40 (ish?) is about

I wonder that too. My guess is there's an outlier datapoint or two there messing with the average. I didn't pull out outliers.

(Since the data is smoothed, an outlier datapoint could influence speeds 2mph in each direction)

What's most striking to me as someone who has heard over and over again about how air resistance is a X^2 property, is the extent to which short (and presumably slow) trips punch above their weight in terms of range consumed per mile. From what I can tell, the actual cost here is the fixed cost of booting up some systems and electronics, and the variable costs of running them over fewer miles can make the MPGe drop.…

That's incorrect. Power consumption is proportional to drag * speed, and drag is speed^2, so power is speed^3, and energy per mile is speed^2.

EPA range is city+highway combined, which isn't really what any most car buyers care about. Range during city driving is irrelevant beyond a point; you're never going to go more than 100 miles per charge. Then the highway test is easy; it never breaks 60 MPH and averages 48 MPH. What most people probably care about is how far you can go between charges when road-tripping, which is really a much more complicated formu…

If I drove my Tesla S on the freeway at 48 mph then I would easily match the EPA rating.
