I did some research and it appears to be along the lines of "clean coal", where they add a bunch more stuff on in order to keep exploding gasoline for propulsion but lower emissions more. I honestly thought the EV in PZEV was Electric Vehicle. Please disregard my derail. EV content to atone: Albuquerque just got a dozen new L3 chargers and we might be able to get the Leaf there now. Maybe. I know you're supposed to only need 83 miles for 90% of trips or something, but when the closest Costco is a 2 hour drive on the Interstate, this statistic isn't very helpful.

Just zero vapor emissions. It's just a cleaner standard than the federal standard was at the time.

Try buying your groceries at a nearby grocery store instead of at the the bulk membership place. Or, alternatively, use the bulk retailer to buy more than a month's worth of food at once so you can just cook from the pantry 45 days in a row. Either of these practices should reduce your need to be a whiney bitch. (USER WAS PUT ON PROBATION FOR THIS POST) (USER WAS PUT ON PROBATION FOR THIS POST)

That was weird. Hey can I ask a silly question because I'm really not much of a car guy and only follow this thread because researching buying an EV made me an EV nerd: Why are Miatas not likely to become totally electric (anytime soon)? Is it because they're so tiny the weight of the battery vs the sportiness of the car becomes a problem?

Yes, exactly. The Model 3 has like 500kg or batteries, that's half of what the whole miata weighs. An electric motor is lighter than ICE, but even if it weighted 0, that wouldn't be enough to offset the batteries. You can either make it powerful and heavy like the Roadster, or light and with short range and no more power than a normal miata, like that conversion above.

Sadly, Slow Is Fast like the MX-5 and BRZ are almost certainly going to be a thing of the past with EV's unless battery tech evolves to something a lot lighter or you accept they are range limited / cost an ungodly amount of money with exotic construction materials. I can only really seeing such smaller and lighter cheap sports cars surviving with alternate ICE fuels as new OEM As a home conversion, you would have to choose at some point to accept limitations for what you want your outcome to be. Remains chuckable and fun? Accept less battery. More range? Less fun but more practical. A single motor Tesla swap with say 35Kw of battery and say just pulling a fairly resonable number out of my rear end for power gains, you end up with a car a touch heavier but up 100Kw and a whooooooooooooole lotta more torque? That'll catch your attention on a track day. Hmmm that's kinda they thing I guess we forget when we think of a OEM EV MX-5, there's potential to be a lot more powerful to overcome the weight increase. 118kW/200Nm from the current ND? That can be easily bettered / doubled with a electric motor. Gaining 200kgs but doubling the power might work for a theoretical Mazda EV sports car? edit : I dont know, I'm just thinking outloud and nothing like this might happen at all.

Yeah, the Model 3 Performance is very chuckable despite the weight. You can hide a lot of weight with sufficient power. It's not a track weapon straight off the showroom floor, but then neither is the MX-5. Convertibles/roadsters also seem to have gone out of fashion, so it's reasonable to assume there won't be much push for an EV in this body form coming soon, neither will any factory EV deliver a full day at the track with similar performance to a current day enthusiast's modded MX-5, which is really up there with touring cars from not many decades ago. But if we lower the bar to "daily driver which is also hilarious in the canyons", I think it wouldn't take much. I'm even enjoying the Skoda Citigo-E on twisty roads because it has some punch out of the corner and feels more balanced than a similar type gas version which is front heavy. There's been some talk of the Cupra being a "hot hatch", but I think that's too big. Somewhere between the Citigo-E and the Honda e is a potential for something "slow is fast" or "small and fun". But again, perhaps not by the modern track day enthusiast standards which can be very high. So I think small and fun or big and fast. Either of these practices should reduce your need to be a whiney bitch.

What is the “one pedal mode” exactly on an EV?

kitten emergency posted:What is the “one pedal mode” exactly on an EV? It starts to regen as soon as you let up on the pedal. Basically it treats the various positions on the pedal as indicating to the computer "go to this speed" rather than "have the engine put out this amount of power". So as you let up the pedal you're indicating you want to be a slower and slower speed so it activates regen to get there. If you let up entirely on the pedal you're indicating you want to stop, so it regens to a stop.

More or less, some cars have regen mode with two pedal driving that's sort of a "mixed one-pedal" where when you let off the accelerator it activates regen, while still requiring the brake pedal to be pressed to come to a stop. They usually let you adjust the strength of the regen, up to going full coast mode though.

Drove my Dad's Kona EV over the weekend. A lot of the minuses are probably related to it being a Kona. Pretty optimistic about the next gen of Hyundai/Kia EVs. Plusses: - Decent acceleration, especially below 30 mph - cooled seats - active cruise control works well - handling is decent - charging in local parking garage was relatively cheap and easy, even in downtown Boston. I think roughly $3 for about 20 kW at a 7kW/h rate - HUD is decent and shows blind spot info, speed limit, turn by turn, etc EV specific minuses: - bad acceleration above 45 mph. Part of this is my own adaptation to the power delivery - the ICE cars will accelerate faster higher in the powerband of the engine, this is not true of an EV where acceleration diminishes incrementally as you go faster, which is a sensation I do not care for. - makes the most god awful artificial noise below 20mph, this was seriously a dealbreaker and I would be messing around to code this out ASAP - I couldn't find a regen setting that I really liked as a manual transmission ICE car driver. 2 was a little too strong and 1 was a little too light. I miss the hand paddle regen on the Volt. I don't care for one pedal driving at this point. Kona minuses: - cheap interior. it's a cheap car but the interior was not good. packaging seemed mediocre and the materials were low quality. Fine on a 20k car, not so good on a 35k+ car. - sight lines, loving thing is like sitting in a bath tub - steering is weird on center and pretty numb - crashy ride, bad suspension tuning and a short wheelbase. - couldn't get the HUD to adjust to where I really wanted in my field of vision

Let's do the simple one first:kitten emergency posted:What is the “one pedal mode” exactly on an EV? It varies between manufacturers but it's basically a way to mix in friction brakes so you don't need to use the brake pedal while driving. The car can regen from high speed, but as the speed approaches zero or the battery is full, you need friction brakes to come to a full stop, hill hold etc. How much to regen and when to mix in brakes deterrmines the feel and usability, some are really good, some are a bit annoying. All EVs (that count as proper cars and aren't airplane tugs or whatever) have regen when letting off the accelerator, even if they don't have a one-pedal mode. Nitrousoxide posted:It starts to regen as soon as you let up on the pedal. Basically it treats the various positions on the pedal as indicating to the computer "go to this speed" rather than "have the engine put out this amount of power". So as you let up the pedal you're indicating you want to be a slower and slower speed so it activates regen to get there. If you let up entirely on the pedal you're indicating you want to stop, so it regens to a stop. This is an interesting interpretation, but not correct. If it was, it would add power to maintain speed when you hit an uphill with constant pedal, but it slows down like normal. Then you trundle slowly up the hill, crest it, and then roll down the other side faster and faster. It is a power pedal, not a speed pedal. Yes, a modern motor controller makes sure it behaves like this way or that, power isn't exceeded etc. But the basic principle is that if you excite the motors windings a little bit, the motor will spin at a certain speed and current will flow in a certain direction. If you then apply an external torque to the motor and make it spin faster, now the motors windings are still excited in the same way but current is flowing in the other direction. In a way it behaves much like a gasoline engine, only that gasoline doesn't flow backwards. If you're going down a steep hill and you've only cracked the throttle open, you can still be effectively engine braking. In practice there is a lot of computer control going on which complicates the principle. The AC from the motor needs to be converted to DC for the battery, the car might be going very fast so regen power has to be limited, there is a certain user experience that has to be just right, the battery might be cold or at a high charge, etc etc. Deep dive here: https://chargedevs.com/features/regenerative-braking-a-closer-look-at-the-methods-and-limits-of-regen/

Most vehicles with the speaker... you can just unplug it. If it throws a code, a 4-16ohm resistor in place of the speaker will usually make it think there is a speaker plugged in. On my Volt I can just pull a fuse to disable it. But the Volt's noise is so low you can barely hear it anyways, it is kinda useless.

FLIPADELPHIA posted:My on plug in Pacifica, the vehicle makes kind of a high pitch whine when driving on battery power. Is that an artificial sound as described here, or an actual product of the vehicle running? At low speeds they are required to produce an audible sound so that animals and visually impaired can be aware of the presence of the car. Technically in the US it's not required to be on, but the automaker is required to provide the option, defaulted to on. It just has to be a sufficiently audible sound, so some cars, like a Tesla, let you change the sound. They sometimes don't let the user change it, or make it difficult to change, since they obviously don't want to open themselves up to liability. https://www.youtube.com/watch?v=cQTBFAgNGR0&t=132s

So is there a comparison for the overall emissions for EV's compared to other transit methods like planes, trains, busses, etc? Obviously they are better than ICE vehicles, but when you are dealing with single occupancy vehicles versus mass transit splitting those emissions out dozens of ways versus the emissions needed to generate the electricity for one person's car may make that a more difficult comparison.
