I have the same problem with owning an iPhone. Even on these forums people are convinced it's some kind of cultural thing. I just wanted a phone that has a nice camera.

People probably think that because the iPhone doesn't have a monopoly on good cameras; I too was just looking for a good camera, and in my research felt like the Pixel 5 had a better camera than the equivalent iPhone and was also $100 cheaper so I went with that. But I think you should use whatever phone you like and don't need to justify that choice

I don't think that any good comes from devoting oneself to a loving brand, of all things; most Tesla fanatics will eventually get over it and be kicking themselves later for acting so douchey

My dad has one, a 2019 I think, and I drove it around a bunch this weekend. It's an EV Kona. It's an incredibly dull modern compact CUV with an electric drivetrain. The drivetrain only cures one of its ills. That mean it's cramped inside, the interior is low rent Hyundai partsbin stuff, the handling is OK, it has a pretty pitchy short wheelbase, there's a lot of road and wind noise, and it's loving ugly. On the other hand, unlike the normal Kona, it's not as slow and was averaging somewhere between 4 and 5 mi/kw, so roughly 2.5-3 cents per mile based on his electricity prices, and it has a bunch of kitted out features like a HUD, ACC/LKA, sunroof, and cooled seats. On the third? hand, it's not cheap and I would have a hard time not finding another couple grand in the budget to buy something nicer. A limited at $42K before incentives is right around Mach E / ID.4 / Tesla 3 territory. If you must buy a Korean EV, I'd still be hard pressed to buy it over the Niro as the Niro is less ugly and I find Kia's interiors more tolerable.

Any specific questions? I can answer or get his input.

Nah nothing in particular, I'm not a car person so I'm just stumbling around looking at numbers and going "this one seems okay, is it though?" That all sounds kind of... lovely I guess. Thanks for the info! Car and Driver kind of led me down this path of considering the Kona

I'm considering a Model 3. The Model 3 and the Kona have roughly the same MSRP, but after incentives (state + federal) the Kona is about $10k cheaper. Plus the Kona's warranty and free service seem pretty excellent. The Niro has the same incentives, so it's like $9k cheaper than the Tesla Model 3, but I wonder whether it's got most of the same disadvantages as the Kona?

I like my e-Niro a lot. Drove several as well as several Konas before deciding. What sold me on the Niro was the additional trunk and backseat space since I have three kids and like to haul things around for camping trips, scouts etc. The Kona was really nice though; I'd say the stereo is better (if you go for the Krell one, might be a different setup in the US?) and the heads up display was very functional (though not as nice as the windshield projection ones on other cars). Had I not needed the space I'd have gone for the Kona since I prefer driving smaller vehicles when possible.

Had initially ordered an ID.4 but after driving a few I decided against it. Didn't like the touch buttons, the interior, or the size. Also thought the software felt a little rough/unfinished. I think in a year or two the ID will be a great choice but VW needs to let it bake it a little longer.

FWIW, I've been getting 550+ km range out of the Niro now during the summer (22-28C outside). But I rarely blast highway speeds. Even when driving ICE cars I preferred taking the smaller roads when going somewhere even if it added a little time to the drive since I hate just sitting on a highway at 120+ km/h for any extended period of time.

PS: ventilated seats loving own in the summer. Had them on my 9-5 Aero and been missing them since. Both the Niro and Kona have them on the top level trims here.

Any additional praise/complaints with the Niro? Maybe I should give one a test drive

Today I had test drives scheduled for the Polestar 2 and the Kia Niro EV. A few days ago I test drove a Tesla Model 3, which I was really happy with; that's a great car that I would love owning.

The Polestar 2 is loving nice. The experience started with a good impression, you just give Polestar an address and they drive a car out to you. Every single thing about the car felt itself felt great, but especially the air conditioned seats blowing cold air straight up my rear end on demand. I didn't know that this was a feature that I wanted until now. After 30 minutes of street driving with maxed out AC and butthole ventilation the battery indicator barely decreased at all, so I feel pretty comfortable with the range. Handling felt great, car was a joy to drive. I also like that it has some actual physical interfaces for things like the stereo volume, and the map display behind the steering wheel is extremely good; I am fine with a lot of control being in the digital display but I do think this is a little better than what the model 3 does, where almost everything is in the infotainment screen. That's minor stuff, ultimately they're both great and it seems like the Polestar 2 is a better experience for a little less range than the performance model 3, and at a slightly lower price, so I'm definitely leaning towards the Polestar

When I got to the Kia dealership they said that they didn't have any Niro EVs on the lot, so I couldn't do the sole thing that I came to do. It's not like I'm a walk in, I booked an appointment online to test drive the Niro EV specifically, and someone called me yesterday to confirm that that's the specific car that I wanted to test drive. We drove around in a standard Niro for awhile, it was fine. I don't really want a hybrid so I guess I'm not buying the Niro EV since Kia seems to not want to let me drive one.

As a previous reply mentioned, a roof cargo box is probably not a good idea.

Loading the car down with stuff increases the mass, which increases the power needed to accelerate to a given velocity and increases the rolling resistance. Adding a roof cargo box increases drag (resistance due to wind).

Below are a couple of examples using handwavey math (e.g. ignoring the integrals and things like hills, cross wind, and motor efficiency).

Given:
P = maV
Fd = cr * m * g + 1/2 * cd * r * A * V2
P = FV
E = PT

Where:
  • P: Power (W or kg*m2/s3)
  • m: Mass (kg)
  • a: Acceleration (m/s2)
  • V: Velocity (m/s)
  • Fd: Drag force (kg*m/s2)
  • cr: Rolling resistance coefficient (typically 0.006-0.015)
  • m: Mass (kg)
  • g: Gravity (9.8 m/s2)
  • cd: Drag coefficient (Typical: ~0.3, Model 3: ~0.23, pre-2021 Model S: 0.24)
  • r: Air density (1.2 kg/m3)
  • A: projected frontal area (m2 roughly the exposed frontal surface area of the vehicle)
  • F: Force (kg*m/s2)
  • E: Energy (Wh)
  • T: Time (s)

Ignoring drag, we can calculate the power needed to accelerate from to a given velocity using the first formula. A Model 3 LR AWD (4072 lb = 1842 kg), taking 10 seconds to accelerate from 0 to 60mph (26.8224 m/s) works out to:

P = maV = 1842 kg * 2.6824 m/s2 * 26.8224 m/s = ~132521 kg*m2/s3
= ~133 kW
E = PT = ~133 kW * 10 s / (3600 s/h)
= ~370 Wh

Adding an extra 100 pounds (45.3592 kg) increases the mass to 1842 + ~46 = 1888 kg:

P = maV = 1888 kg * 2.6824 m/s2 * 26.8224 m/s = ~135830 kg*m2/s3
= ~136 kW
E = PT = ~136 kW * 10 s / (3600 s/h)
= ~378 Wh

Drag is trickier, but if we assume a constant velocity of 60mph (26.8224 m/s), reuse the same car (cd: 0.24, assuming A = ~2 m2), and plug that into the second and third formulas, we get:

Fd = cr * m * g + 1/2 * cd * r * A * V2 = 0.015 * 1842 kg * 9.8 m/s2 + 0.5 * 0.23 * 1.2 kg/m3 * 2 m2 * (26.8224 m/s)2
= ~270.7 kg*m/s2 + ~198.6 kg*m/s2
= ~ 470 kg*m/s2
P = FV = 470 kg*m/s2 * 26.8224 m/s = ~12588 kg*m2/s3
= ~12.6 kW

Adding an empty cargo box increases the projected frontal area (A) and drag coefficient (cd). If we assume the empty cargo box increases A by 0.5 m2 from 2 m2 to 2.5 m2 and cd by ~25% from 0.24 to 0.3, we get:

Fd = cr * m * g + 1/2 * cd * r * A * V2 = 0.015 * 1842 kg * 9.8 m/s2 + 0.5 * 0.3 * 1.2 kg/m3 * 2.5 m2 * (26.8224 m/s)2
= ~270.7 kg*m/s2 + ~323.7 kg*m/s2
= ~594.5 kg*m/s2
P = FV = ~594.5 kg*m/s2 * 26.8224 m/s = ~15947 kg*m2/s3
= ~15.9 kW

We can counteract increased drag from our empty cargo box by driving slower:

V2 = (~470 kg*m/s2 - ~270.7 kg*m/s2)/(0.5 * 0.3 * 1.2 kg/m3 * 2.5 m2)
V = sqrt(~199.3/0.45 m2/s2) = 21.0290 m/s
= ~47 mph

There are studies which talk about this in more detail (with sometimes confusing results), but in general anything that increases the drag coefficient (cd) will dominate at anything above moderate speeds.

Nothing above is EV-specific, but EVs have less energy capacity than ICEVs (because batteries are expensive and heavy, and because EVs much more efficient than ICEVs), so the effect is more pronounced.

Just out of curiosity, how does Tesla handle test drives? I haven’t done a ton of test drives (of ICE cars) in my life, but the few I have done have been all over the place. Some places insist that the guy goes with me and we just drive around the block, other places just toss me the keys and tell me to be back in a couple hours.

I’m not in a place to actually buy anything until probably spring 2022 at the earliest, but I would like to give the Y a spin and see if it gets the wife approval or not.

I test drove a model 3 a few weeks ago, the dealer shows you the relevant options, has you adjust the mirrors and seat, and then asks you to come back by a specific time. My appointment was for 30 minutes but the dealer just said to bring it back by 5

Yeah even if you don't have any kids or other big deductions/credits, married filed jointly doesn't hit $7500 in taxes until around $90k annual income. Median household income is more like $60k. The vast majority of Americans are nowhere close to being able to reap the full tax credit of an EV purchase, and there are some very affordable EVs these days that you can buy on a loan while paying practically no interest.

But I still think that $7500 capped is better than the hypothetical $3000 uncapped that some other goon proposed, that would make no sense

I don't know what's going on with used car prices but it looks like I can sell my 2020 Model 3 privately and get a 2021 Model 3 with the heat pump and all that jazz while only taking a 2k hit on depreciation thanks to the federal incentive. The power liftgate and other improvements are fine but that heat pump would be really nice for Canadian fall/winters. Normally I would never entertain selling a 1 year old car but this situation is pretty unique and kind of nuts. The only thing that might stop me is that it's a pain in the rear end to sell a car privately up here.

Unfortunately, new Tesla purchases in the US no longer qualify for our federal incentive, and that helping push me to get a Polestar 2 instead. What's the Canadian incentive look like?

I dunno, MSRP limits are hard to argue against. Yes they're counterproductive if your goal is to get as many EVs into the hands of as many people as possible, but there's always the argument that if you can afford a Model S, you don't need government assistance. It could be set a little higher, but there's probably a reason the model Y starts at $39,990 US. In Canada, trim packages that boost the price past the MSRP rebate limit don't count against you, so you can max out the option list as long as the model is on the list. The income limit is pretty arbitrary though, because it locks out a whole lot of bay area Henry's earning 6 figures and living in bedsits, as well as being completely gameable by the wealthy self employed/incorporated.

It's easy to argue against msrp limits, your second sentence effortlessly gives a really good argument against them. If the goal is to speed up ev adoption then the incentive should exist for all prices and manufacturers, with no limits (yes, get rid of the manufacturer limit too, let Tesla buyers back in). If it's specifically to help lower income people afford an ev then instead of an individual rebate we need to reimburse dealers who apply the discount directly to the sticker price

Then the map data should cover this case, and if everyone is relying on it to be accurate, there will be more incentive to keep the speed maps accurate.

I'm just tired of having people ride my rear end when I'm doing 10-15 over (and I have to do 10-15 over to not die). Driving is so needlessly aggressive these days. If the speed limits aren't sufficient, we should change them. Regardless, we should enforce them, and not sell people cars based on their ability to go speeds far higher than an untrained driver ever should.

Oops a bug in the software made your car pull speed limit data from somewhere in the Arctic Ocean, it wasn't able find any speed limits for that region so it returned a value of 0. Thankfully some developer decided that the minimum should be 10, but that doesn't help much when you're on an LA Freeway.

It sounds like you're saying that people following the law are a problem because they make people who break the law mad. Why do we placate dangerous drivers so much? If everyone drives 80, make the speed limit 80. But send tickets to anyone going >=81.

Defensive driving requires that you do a lot more than assume everyone is following the letter of the law, hth

Refusing to let others pass you creates a problem because you are refusing to create safer driving conditions out of a feeling that speeders need to be punished. But your job is not to punish speeders, it's to drive safely, and that means pulling into the right lane to let others pass you

I test drove the 2021 model about a month ago and really really liked it, it felt much better than my test drive with the Model 3 (which was also great, just not as good)

Exactly. There are a few clips out there of people avoiding getting rear ended while stopped due to traffic by using EV acceleration to get on the shoulder or otherwise get out of the way. I'm sure that ability is even more important to two-wheelers when some dipshit doesn't see them.

Quick acceleration is definitely a safety feature in any situation where forward is the safest way out.

Where to draw the line between useful and just there for fun is obviously subjective, but some people here are acting like no one has ever floored the accelerator for reasons other than their own entertainment.

Okay but the original topic in which "safety" was raised wasn't about acceleration in general, which is high across the board for EVs. It was in the context of nerds comparing 0-60 acceleration stats and being like "well this car is better because it can reach 60 mph 0.2 seconds faster than this other car" and constantly slamming hard on the accelerator regardless of whether it's safe or reasonable to do so

No one's saying that EVs need to have their acceleration decreased or whatever, someone was just making light-hearted fun out of car bros
