If I had a 'conventional' car that averaged 20mpg at 50mph, what would be a good estimate to miles/kwh as a conversion?

stevewm posted:Norwegian YouTuber Bjorn has been posting Mach-E testing videos... https://youtube.com/user/bjornnyland You want to fast charge anywhere near the rated speed? Choose between heating the battery or the interior. Ford is really taking the "fix it in software" stance to this flagship vehicle. I've watched several Mach E reviews and none seem to really test the EV platform like they should, except for Bjorn. Thank you Norway, for your EV commitment, so we can see how these things perform outside of perfect weather while having a good charging infrastructure. VideoGameVet posted:It's more about "how much battery does a conversion need to go X miles if the original car got Y mpg." You're thinking about this wrong. You'd need to figure out how much drag it has (probably other things as well). The original gas motor is horribly inefficient and has no bearing on how an EV motor will perform in that same chassis.

That's a lot of hyperbole, there are countless brushed DC low voltage lead acid drivetrains that set back the cause of electric vehicles by decades. By comparison "lack of battery thermal management" is an inconvenience  obviously depends on the climate where you are though.

So less range and about halfway between a performance and AWD-LR Model Y for 0-60?

Watching the Mustang Mach-E videos, I'm kind of "whelmed" with the car. It really feels like a case of barely meeting expectations instead of trying to exceed them. I was hoping for a bit more ambition from Ford with their first mass market EV. The infotainment has some good ideas (love the energy use breakdown!) but performance doesn't look very good, lots of lag and hitching. I don't know how car companies keep getting that so wrong either. If you are going to make a big screen that the user has to interact with then the first priority has to be that it is fast and easy to use.

Getting word that some dealers have demo ID4s here (Sweden) now and a handful of people have posted comments after driving then. So far very positive, one guy thought the display still felt "slow" so the software likely needs some more work (not sure if this car had the 2.1 release they are supposedly waiting on before releasing the cars to buyers). Apparently very comfortable seats (VW usually does well here) and the car reported under 0.2kWh/km despite "spirited" test driving.

PIZZA.BAT posted:ford just released the expected specs for the gt: https://www.ford.com/suvs/mach-e/models/mach-e-gt/ Those numbers definitely look like I can forgo the GT version and just stick with the Premium AWD version if I decide on a Mach-E for my next vehicle. After scheduling a Mach-E test drive for Friday, I followed it up with a Tesla Model Y test drive a little bit afterwards the same day. Figured I should actually give the thing a shot, and see if the design decision like no gauge cluster actually bother me. I was surprised to find out poking around on YouTube today, that the Model Y doesn’t “officially” have a heated steering wheel yet, but has probably had that added on since the beginning of the year. Was pretty surprised to see that was missing. Also that Sirius XM either isn’t available in the vehicle, or is app based. I find that surprising as well.

No Gauge cluster bothered me on my test drive of a Model Y, but it's absolutely something you will get used to if you buy it. I do wish they would have options to have certain things like trip miles and tire pressure displayed at all times - but it's really not necessary. You don't need some of the information that is typically displayed on an ICE vehicle like RPM and oil temp (honestly are these even needed on modern automatic transmission ICE vehicle?).

I haven't watched the video yet, but I like that feature. Maybe the Ioniq 5 should copy it, although the U.S. long range model will have a very tiny frunk. Kona EV battery recall, d'oh: https://www.autoblog.com/2021/02/24/hyundai-to-replace-kona-ev-battery-packs-recall/

Steer by wire is a pretty well proven concept for vehicles operating in controlled environments. They're pretty robust systems, but the main reason for them is packaging, weight, cost and maintenance reduction.

Yup, and I think it's part of how they have a wheelbase larger than a model S, while actually being smaller than a model Y. No steering column = less space taken, maybe even safer in a way, although we've had collapsible columns forever. But technical details are sparse, so I'm just speculating.

Brakes are arguably a more important safety device than steering, and they've been electrically controlled for ages. I get the resistance to it but it's pretty trivial to make it multiply redundant. Hell with auto driving capabilities, if the connection to the wheel was somehow severed, the computer can still dynamically control the car's direction .

Adaptive cruise controls and lane assist systems already have the potential to kill you several times per day, it'll be fine.

Took a Skoda Citigo-E on some twisty roads today and it was actually a great time. I usually just drive it in the city or on the highway, the latter is really annyoing due to the sharing service cars not having cruise control. But on low speed twisty roads it really shines. Much more balanced than a FWD ICE, darts into corners fairly flat and has plenty of punch out of them. Steering isn't Ferrari-like direct exactly, but it's certainly not vague. Now, if the ID platform brings some RWD mini cars with more power....

Pray your noodle arms can manhandle a car that's never been designed to steer without power assist over to the shoulder? If all 2-3 position sensors all fail (or it has the old "if one sensor fails we dump the output of the other ones because we can't trust which is correct" logic), lane keep will keep the car in the lane, then just put your hazards on and brake until you can get somewhere safe.

As far as drive-by-wire, Infiniti has been doing it in some of their cars since 2014, though they still have a mechanical system as a backup, at least for now.

I would hope that it's setup similar to air brakes where the default state is braking and you need some kind of force to release the brakes. At least that way the thing will stop if something goes wrong.

If you have a failure in a control system on one side of the cockpit, you can take over on the other side - Not so easy to do if you have a single operator vehicle. So if the flight yoke isnt working correctly for the captain? Co-pilot can take over. Basically just another way to say redundancy is baked into aircraft esp commercial craft quote:What's the fallback when your power steering fails? Pray your noodle arms can manhandle a car that's never been designed to steer without power assist over to the shoulder? A lot of power steering systems drop most assistance at speed and at low steering angles. Some remove it entirely so.... yes? One of my cars lost it's power steering and apart from tight maneuvers it was perfectly fine to drive. If you dont have the arm strength to guide a car to the side of the road if the power steering fails you probably shouldnt be driving.
