The Chinese have a car that has such a battery. Some western manufacturers have 450+ mile range.
Lucid has a really long range EV, the Air, at up to 512 miles. I've ridden in one once, used by a car service in the MSP area, and it was impressive. Their Gravity SUV, up to 450mi, is just now launching and should be very popular. American company, too. Tesla's highest-range BEV is the Model S AWD with a rated range of 410mi.
The much less expensive Tesla Model 3 LR RWD exceeded its EPA rating (363mi) on a 70-mph range test by Out of Spec reaching about 380mi. That's a pretty good range for $34,990 after federal tax credit, $42,490 without.
I did some searching on longest range BYD BEVs and came up with their Seal BEV with a rated range of 700km (435mi) but that isn't using the WLTP rating criteria so don't know how that compares to WLTP or EPA rating. WLTP rating is more optimistic than the current EPA rating. Their Tang has a WLTP rating of 530km (335 miles) but it's difficult to get sales numbers as they published combined Tang numbers for their BEV and PHEV Tangs. No data on how many are BEV.
I found that data from searching for BYD's longest range BEVs. I didn't find anything that was well ahead of the longest range US BEVs from Tesla and Lucid. What models should I be looking for?
As far as the car's software, I was an Android Auto user, in Mazdas, before buying the Tesla. Haven't missed it at all. Legacy automakers have traditionally outsourced their software development. The EV companies with the best software, Tesla, Lucid, Rivian, etc., do it in house. I don't have any experience with the Lucid or Rivian software but it has gotten very good reviews.
As far as the app, additional functions that I've found very useful are,
1. Valet mode. I park my car at an airport valet while at work. I put it in valet mode and get notifications if its left unlock and each time it's driven. It will also give notifications if doors, windows, frunk, or truck is left open for extended periods of time and they can be closed (except for the frunk) from the app.
2. Climate. In seasons with extreme temperatures, I use the app to activate climate control when I land at home. By the time I get to the car it is comfortable and, in very cold weather, the battery is up to operating temperature. Defrost mode will have the windows clear, too.
3. Sending a destination. I'll send a destination from my phone to the car and it'll be ready to navigate when get in. If I search for my destination on my phone's map app, I can send that directly to the car without any copy/paste or re-typing.
4. Summon mode is handy in specific situations when the weather discourages walking across the parking lot. Don't use it often, but it's nice is those situations.
5. Sentry mode live video and recording can be viewed through the app so you can check on the car or see what happened if the alarm is activated.
Last night I had my first experience with the newly enabled adaptive headlights. My 2021-build has had the matrix headlamps since new but they weren't approved in the US until recently. The matrix headlights have individually addressable pixels which the car controls independently so that you can drive around with the high beams on even when there is other traffic. It turns off the pixel which would shine on the other cars around you leaving full high beams wherever there aren't any other cars. It was impressive. Now that the US allows adaptive headlights, I think you're going to see them adopted quickly across manufacturers.
