Tesla's design innovation was making an electric car that didn't look Different Because Electric.

Actually the weird fish-shaped van thing form factor is common in electric vehicles because it's aerodynamically the best way to shape a box full of stuff (especially if you don't really care about downforce).

For instance, see the Mercedes fish van:


Tesla doesn't have this shape because it's a pretty impractical car. It has four doors but the rear seats are tiny and have a low roof so it's pretty much a 2+2 coupe. I can't even sit in the back without my head touching the roof. Also, the Tesla approach of brute-forcing range makes it less sensitive to packaging and aero concerns.


The Bolt's design brief is very different - deliver an electric car for "normal" people. So it has to have a range of 200 miles, cost $30-40k, and fit 4 adults. That means very aggressive engineering to keep costs down while maximizing range and usable space.

The most impressive thing about the design of the Model S is that it has the lowest drag coefficient of any production car and still looks attractive. I'm also pretty sure it has the most cargo space of any electric sedan. It is also seats those under 6 feet comfortably in the back row. Pretty sure if you're over 6 feet you're going to feel cramped in a lot of back rows.

Edit: I've only owned Model S's with the panoramic roof which supposedly adds an inch or two of clearance in the back. Were you sitting in the back of once with a solid (non-glass) roof?

What is it about a drag co-efficient of 0.24 that's so hard to get past? The only cars noticeably better are essentially prototypes. Are the engineers running into fundamental limits of painted-metal-in-air?

The new Prius is supposed to be the same, as is the S-class, etc. The reason you see so many luxury sedans on that list is probably because they're riding on airbags and can lower the car on the highway. In that way, the Prius is probably superior because it achieves similar c/d without air suspension.

I bet it's more of a high-speed handling issue. Most cars due to their shape just inherently generate lift, so you need to generate enough downforce to keep the car planted at whatever your projected top speed is, and downforce creates drag.

Edit: other possibilities off the top of my head are ride height and the fact that people hate wheel well covers

Bolt looks like a pretty generic vehicle to me idk. I am a huge fan of the Volt even though I would never buy one because they purposefully designed it to be a rather masculine look that is good enough to prevent the hordes of car people with fragile male egos from making GBS threads on it for being too cute/foreign/nontraditional yet it's still pretty distinctive.

I don't think this design is as groundbreaking as the Volt even though it does seem to be trying to straddle that same line, but hatchbacks in general aren't really "masculine" in the first place so it doesn't come off as well as the Volt. It looks like a nice hatchback though, which sell well, so it will probably do fine.

Automakers also know EVs are still niche vehicles, and while you want to appeal to as broad an audience as possible, they need to still appeal to those in the market for EVs. They also know that EV shoppers want to flaunt their purchase and stand out in the parking lot.

Hence, mass-market EVs tend to look more unique than their gasoline powered equivalents. Does the Bolt look good? I like hatchbacks and the shape of the i3 (but I loathe the tricolor scheme) so it appeals to me. It looks different enough to say "I'm not your usual car" but also not too far into i-Miev territory.

Yeah. The Prius is a well-made car, but a lot of the reason it so massively outsold the other hybrids on the market is because it was the first one to look like a weird little space pod so you could show off your eco-consciousness to your neighbors.

Honda has had a hybrid Civic on sale for the last 15 years, but you'd never know it because it looks just like a regular Civic, and that's the last thing somebody wants when they've spent a premium to get a hybrid.

I'm not disagreeing that that is a big factor, but what it doesn't take into account is the practicality of both cars. The civic is extremely hampered by the compromised trunk space and lack of split fold seating. It simply would not work as a family car, whereas that is precisely what the Prius is designed for. So looks aside, you get better fuel economy and more useful space for about the same money with a Prius.

Yeah and nowadays as even small cars get wider and wider frontal area is becoming mostly a function of how tall the roof is.

This is part of the reason the Prius’s cd is so good: it’s relatively tall, so it needs a low coefficient to counter its high frontal area.

I actually found that the Leaf isn't that bad in terms of looking different from a normal car. Short of a Tesla, which is just way out of my price range, the only car that I found which looked normal enough to consider driving. I've had her for the last few months (2012 model) and I've been happy with it so far.

Mange Mite, I always thought you hated Tesla and the Model S as your posts read very negative on electric cars and Tesla in particular, but it seems you own one.

Do you like your car? Am I right that you are down on the electric car thing? Presumably, if so, that happened after you bought one. What changed your mind?

Apologies if this comes off as stalking, I'm just generally interested in your opinion as an owner who seems at least sceptical if not downright negative about the whole thing.

I like this. It's pretty much what I want would accept in a compact-ish, cheap-ish car. Flat backend is easier to park, not too much room for luggage but it should at least have folding rear seats. I guess the front space is all motor. Side and front visibility looks to be good, hope it comes with a reverse camera. It does look a bit bulbous and fat, I'd appreciate cleaner lines. 200 mile ideal electric range, I guess that means a 40 kWh battery with Leaf-like consumption. Just needs fast charging - I would prefer CHAdeMO over here.

I don't really own the Tesla anymore but basically I'm not actually skeptical of electric cars so much as marketing hype and also Tesla's business practices in particular. They do some pretty shady stuff financially (no worse than many other overblown tech startups of course) and I'm not a fan of the cult of personality Elon Musk inspires. From a technical standpoint, too, people seem to buy into the marketing without looking at the concrete stuff versus all the future possibility fantasies they spin.

That factory, for example, they were throwing out overtly optimistic projected dollar numbers, and touting investments from potential partners even when said partners hadn't even committed anything yet. And in general, be suspicious of any company that refuses to follow GAAP.


It's not a bad car (except for that godawful touch screen) and, although you'll never actually save money, if you want one it's actually being subsidized by the tech bubble so go ahead and get one if you want it. I wasn't really blown away but then again maybe it's because I'm comparing it to similarly priced conventional cars.

I was under the impression that the MQB platform was somewhat made for fully electric cars also?
I have a 2016 e-golf myself and it's really no different from the regular golf except there's a lot of unused space under the hood. The floor and trunk looks identical, so I guess the batteries are just crammed in wherever the exhaust, gas tank and other normal car stuff would be...

I'm sure they had electrics at the front of their minds when designing it, but part of the compromise was making most of the parts fit both types of car so they didn't need two different production lines - or at least, as little difference in production as possible. As you say, they appear quite similar inside. The nature of the electrics give them much more freedom of form, so you'd want to avoid the compromises of an ICE drivetrain.

The e-Golf has the gearbox tunnel for instance, while the Tesla has an almost flat floor. People are actually adding a center module to gain more storage. Compare insides:










A flat slab with a wheel in each corner could basically be a Phaeton, a Transporter, a Lamborghini, an A7, a Golf...just depends on the size of the main bit and the attributes of the added bits. The e-tron Audi Quattro concept looks like this. If you consider talks about a Combo charging system capable of 150 kW (faster than Teslas Superchargers) as well, pretty amazing things might come out of the VAG. *ahem*
