I don't own a high-performance car and have never driven a Model S, but to me this car is truly unique in it's category.

You can't compare the Model S with gas-powered engines that had many decades to be refined. Considering everything, the Model S appears to have made a larger jump than any other car in recent history.

It's not designed to be raced on a track, but it does give you an edge in some situations where any other EV or most gas powered vehicles won't.

Well, there's nothing in a Model S that is earth shattering in terms of technology.

The batteries are used in laptops and model airplanes. That technology has been around for ages and continues to improve well outside of the automotive industry.

We've known how to make super high efficiency electric motors for, well, I am only guessing, a century [1]. Large electric motors that are over 90% efficient were built decades ago. With the shift to brushless Cobalt and Neodymium based motors we've been able to shrink them and increase their output power. Again, I'll use the example of the early pioneers in model airplane electric flight who were building high efficiency 2KW motors that fit in the palm of your hand decades ago. Switched reluctance drives have also been around for decades, they can deliver insane amounts of power in a very small volume with no magnets and really good efficiency. Control is more difficult.

If I had to guess I would suggest that the advances brought forth by Tesla have been in control and safety. Building a huge battery pack that is safe in a crash requires careful engineering. They had to figure that out. Of course, they build their own motors and have developed their own advanced control electronics for these motors. The rest is, if I dare say, standard automotive engineering work.

Again, not diminishing Tesla in any way. I am just countering the "walking on water" aura that seems to orbit around anything Tesla. They should be praised for what seems like flawless execution and laser-like market focus. They are building a fantastic world-class high-end electric car. And it is fantastic. Supernatural? No. A work of engineering art? Absolutely.

Of course the car or company is not supernatural. But there's a HUGE difference between saying "anyone could have done it" and ACTUALLY doing it. That's the key to understanding the reviews.

I am not sure anyone is reviewing the electric motors. They are not reviewing how efficient their motor is or even how small it is. They are reviewing the car as a whole.

I believe you can say similar things of any market leader. Rarely does someone change a market and invent great technology or are involved in engineering marvels. But they do solve the problem in such a way that is significantly gives them a lead.

Is Tesla the market leader? Nissan's Leaf is the best selling electric car in history.

I don't think we disagree. As I pointed out, they excel at execution. Few ideas in electrics are new. This could very well segue into a discussion about patents, because some of the same issues exist there.

Given enough funding, a team of capable engineers and a solid vision (both of which are present at Tesla and other companies) the expectation of results should be the norm, not the exception. We, as engineers, are trained to solve problems using the scientific process.

To use battery packs as an example, there are probably thousands of engineering teams around the world who could design excellent battery packs that could withstand the rigors of automotive use. Tesla (and others) don't happen to have the only 12 engineers in the world who can do that. The same could be said of motors, electronics, software, suspension systems, chassis systems, etc.

I --and this is just my own bias-- am not impressed by what I consider to have to be the normal result of posing a problem to a capable group of engineers. That is to be expected. If you can't expect that out of engineers there's something seriously flawed with the way we are trained.

Of course, there's a continuum of capabilities out there. There is such a thing as lousy engineers with no imagination and a lack of understanding of reality despite years of schooling. Hiring is important. A company forming a substandard team will produce substandard results.

The patent segue is that there really isn't a lot today that most of us would consider to be true invention. Most everything being patented are implementations, which is a tragedy.

What is hard in the context of an organization, despite money and possibly vision is to execute on a consistent basis, keep focus on a reasonable mission and do so on a timely manner and within a reasonable budget. A good comparison of a polar opposite to a company like Tesla is just about any government-run organization where money is never a problem yet they fail to deliver consistently on even the simplest projects.

Tesla doesn't walk on water, but they have been executing a vision in what appears to be a constant series of flawless moves. They have good people who obviously work well together, they seem to know very well where they are going and, of course, they have the drive and funding to make it happen. Larger car companies could very well have to try to push the same ideas forward while mired with unmotivated and inefficient teams that just can't get anything done at the same time scale. And then there's the organizations themselves getting in their own way, AKA, "The Innovators Dilemma" [1]. There's plenty of history on that last point.

To some extent Tesla doesn't have to be a super organization, they just have to keep to their mission and they will outplay everyone else who is still failing through good management while trying to sell 5.25in drives because that's what their customers tell them they want (a reference to the book).

Subsystems integration is an engineering discipline in its own right, and is perhaps the one with the greatest impact on user experience. The SI work that Tesla does is not often mentioned but IMHO it's a big part of the secret sauce.

[rebootthesystem]

It's execution, which I did mention as their strength.

[TrainedMonkey]

That is precisely his point, you can't, but all the reviews do.

[scott_karana]

Electric motors predate the internal combustion engine, keep in mind.

But how many resources were spent on improving EVs and how many resources were spent on improving ICE-vehicles?
