I would think that, given the choice of a) making an EV just reverse the electric motor itself, which probably requires no additional parts and b) using an actual reverse gear (with all the added moving parts that brings) the solution is obvious. I'm not sure that it would be possible to "damage" an electric motor by reversing it while its still moving forward, since it's just making a magnetic field do the work. Correct me if I'm wrong!

Fair enough! Tesla offers no strings attached test drives, give it a go one day. I think you'll be surprised. One thing that might annoy you is the creep function. Other EVs also have this. If you're standing still in drive with brake on, hill hold is active. Once you touch the accelerator, the car will creep forward until it comes to a full stop with brakes on again. I like it because you can be more precise inching forward by braking a creep then by pressing the gas gently. Don't like it? Switch it off in the config menu. MattD1zzl3 posted:It sounds like they knew EV motorcycle buyers would want to shift their own gears as well and made that work. Maybe, but with that particular bike I think it was an engineering choice more of a customer demand. It's supposed to be a track capable bike and with a single speed it tops out in the straights too early. ilkhan posted:And most have a 1 speed transmission to add a reverse gear, not straight direct drive. Nope, they spin the motor backwards. I think most can even regen backwards. They do have a box with some cogs and gear oil in it though and it can rightly be called a gearbox. It's just that the gears can't be shifted.

Oh I had an actual question that I'm having a bit of trouble googling for, about EV fuel economy. - Does EV mileage suffer from start-stop traffic to the same degree ICE vehicles do? - Do EVs lose proportionately more range for being a lead foot (i.e. gunning it to 45 as opposed to accelerating sedately from the light) like ICE vehicles? - I stumbled on a random sentence somewhere last week saying someone's EV range was worse on the freeways than on the side roads for their commute, despite similar range, which confused the hell out of me. Don't even remember where I saw it, is there remotely any truth to that? Ciaphas fucked around with this message at 01:01 on Jul 24, 2015 |

Ciaphas posted:- Does EV mileage suffer from start-stop traffic to the same degree ICE vehicles do? These are pretty simple, common questions. Answer to the first one is no, opposite from ICE vehicles, stop/start traffic is more efficient than highway traffic for EVs; it is actually the most efficient type of road condition to move an EV in. This is due to regenerative braking and reduced aerodynamic drag. Answer to the second one is yes, driving faster makes you lose more range than driving slower, mostly due to aerodynamic drag, which is a force that rises exponentially with speed.

I'm not sure that it would be possible to "damage" an electric motor by reversing it while its still moving forward, since it's just making a magnetic field do the work. Motor/generators are funny. There's a lot of stuff going on under the hood, so to speak, that to the layman just looks like "no moving parts! ". But there's a whole poo poo load of moving electrons! And boy howdy are they moving, and they don't much like being told to move the other way. Now you can totally design a system to take that into consideration, and it might be a more robust solution than just slapping on a reverse gear, but if you think stopping an electric motor spinning one way and start spinning the other way is a non-event, a lot of expensive engineering has gone into making it so. If it helps, think of a reciprocating engine, and ask yourself why you can't just vary the timing to start spinning crankshaft in the opposite direction instead of having a reverse gear. Same basic problem to overcome; what the gently caress to do with all that energy. It's just *easier* to deal with the physics with electromagnetism.

Ciaphas posted:- Do EVs lose proportionately more range for being a lead foot (i.e. gunning it to 45 as opposed to accelerating sedately from the light) like ICE vehicles? I needed to drive an extra 30 miles today above normal and forgot to hit the charging over-ride button last night to get a full 100% charge instead of the usual 80%. I drove in to work this morning taking it easy (not hypermiling but definitely trying to be good) and it used fully 1/3 less of the battery than I usually do being a lead foot. That said, electricity is so cheap that I'll be back to normal tomorrow. I love being able to drive a good road aggressively without burning $5 in gas to do it. Edit: Something I don't think most people mention: I love being able to attack a curve without having to either lug the engine at the entrance or run out of revs on the exit. I can be on the power all the way through. You also don't have to worry about an automatic shifting halfway through and losing traction (but who wants to drive one of those through the curves, anyway?).

Can the Tesla safely run while you're not in it for awhile? I remember hearing something about like how you can have it start the AC and all that before you get in, is it safely locked during that time? I was just wondering if you actually could leave your dogs in the car or whatever because you could keep the AC running while the car is locked while you're eating or whatever, but I would probably be too nervous to do it anyway since you couldn't really tell if it turned off for some reason.

Same basic problem to overcome; what the gently caress to do with all that energy. It's just *easier* to deal with the physics with electromagnetism. Funny thing, some snowmobiles (and possibly other similar vehicles) do exactly this for reverse, they literally run the engine backwards. It's only practical with two stroke motors currently (though presumably an independent valve control technology like Koenigsegg's prototype could make it workable with four strokes) but it does work. IIRC Ski-Doo turned what had previously been a quirk of two strokes that happened accidentally from time to time in to an actual controllable thing in the late '90s. I remember reading an article in Popular Mechanics about it when I was a kid but I have no idea what terms to search to find it now.

The car (drivetrain, etc.) doesn't turn on, just the climate control components. It stays locked. You can monitor the climate control state and internal temperature from the app. You'd still risk having someone break open your window because they don't know it's being cooled, I suppose.

I went and test drove a '15 LEAF (that's an acronym? Huh.) today, first time I've been in an electric (not even been in a hybrid before). I'm surprised by how much I enjoyed the driving experience; I guess the instant torque of an electric motor and direct transmission makes the difference for my style of driving. Brakes didn't feel mushy, like I was told to expect for an electric/hybrid, either--or at least not different enough from my current car ('14 Mazda 3 if anyone cares) for me to notice. Surprised at how much passing power it had--only took a couple seconds to get from 65 to 75 or whatever to pass on the highway, and it easily passed the "Can this car get to highway speed by the end of a short merge lane e.g. the 215W/Eastern entrance" test despite my fears of cheaper electric cars being gutless after 45mph. Two years for my lease to expire can't pass soon enough now

I'm kiiinda considering maybe getting a Tesla this year or next year possibly, my car is almost at 100k miles and is going to cost a ton to maintain probably (Jaguar XF with the supercharger), so it might even save a bit more than the $17k gas/tax credit. Counting those off the purchase price and selling my current car for like 20k, that's a net of like 50k for an 85d which is pretty doable. The main reason I might actually do it is just the safety thing, as far as I can tell the model S is literally the safest thing you can possibly drive, and since I can afford it you can't really put a price on safety, or if you can it should be worth a lot I think. That might be thing that actually lets me rationalize getting one, not the fossil fuel part or the part where even the middle trim one is fast as gently caress (4.2 is almost a full second faster to 60 than my current car which I feel is already pretty drat fast). I can't really decide how long to wait for them to like slightly improve the interior or get other minor features that I'd kinda like, like a HUD (I know it's silly but I actually do feel like it's probably better for safety and also just pretty cool and if BMW and MB have them I assume Tesla will have one before long). I've heard mixed reviews of the current interior but I've never seen it myself in person. I know it's shallow but the interior quality does matter to me a decent amount, especially with a car of this price point. How do the test drives work anyway, in states with no dealerships (I'm in NC)? Do you just schedule some time and they like bring it to your house and you go drive around wherever you want together or do you have to go meet them somewhere?

Someone correct me if I'm wrong, but Tesla stores aren't dealerships, in the traditional sense. They're literally just outlets for Tesla Motors to sell their products. They'll have a limited selection of examples on hand for test drives, (my local Tesla store had two S85s an S85D, and a P85D, last time i was there,) but they don't maintain stock. They simply exist to give prospective customers a place to look at/sit in/drive the car.

Yes but in some states there some pretty heavy restrictions on their ability to actually SELL the cars. Like here in Utah, the SLC Tesla store can't actually sell any vehicles. They talk to people and I think do maintenance.
