Whereas researching my e-book, Tesla: How Elon Musk and Company Made Electric Cars Cool, and Remade the Automotive and Energy Industries, I used to be lucky to have the ability to interview two of the Tesla founders, Marc Tarpenning and Ian Wright. Wright supplied some eager insights about Tesla’s techniques strategy to its software program, which was the other of the best way the legacy automakers have been (and principally nonetheless are) doing issues, and this turned out to be certainly one of my favourite elements of the e-book.

He made these feedback in 2014, and he was referring to occasions that had occurred years earlier, however what he mentioned is to a big extent nonetheless true right now, and since then many writers have echoed Wright’s statement that Tesla’s techniques strategy is certainly one of its best aggressive benefits. I bought a whole lot of mileage out of that interview—I’ve referred to it in a minimum of a dozen articles.

When it created Model S, Tesla modified the best way automobiles have been developed and manufactured, though not ways in which have been apparent on the time.

“The best way that Toyota manufactures a automotive, the best way they stamp the steel and weld them collectively and paint them and do all the inside bits and put the automotive collectively, it’s type of laborious to beat that. I’m undecided that Tesla’s made any advances on that, and even gotten to the extent of doing that,” Ian Wright instructed me. “However, should you’re a Silicon Valley expertise engineer, and also you take a look at the best way trendy automobiles are designed from an electronics viewpoint, to make use of an Australian expression, it seems like a canine’s breakfast. It doesn’t seem that they’ve what we might name a techniques structure.”

Folks usually describe the trendy vehicle as a “pc on wheels,” however it’s actually extra like a pair dozen small computer systems, not one. In contrast to a contemporary pc community or software program utility, a (non-Tesla) automotive shouldn’t be designed as a single system—it’s a mishmash of separate, incompatible pc techniques, each sourced from a unique provider.

“I’m looking the window at my 2008 Volkswagen Touareg, and I wager that’s bought sixty or seventy digital black packing containers, 300 kilos of wiring harness, and software program from twenty completely different firms in it,” mentioned Ian Wright.

“The most important reliability downside with these automobiles is the electronics and software program. I feel Tesla did take an actual Silicon Valley techniques structure perspective in designing all of the electronics within the Mannequin S. I don’t know to what extent that approach of doing issues will translate to the large guys, however I feel it’s a very completely different approach of doing it and I anticipate that their electronics and software program will wind up being fairly a bit extra dependable than what we’re used to in automobiles.”

All of the software program that runs Mannequin S is built-in as a single, logical system, which suggests, in line with Wright, “fewer black packing containers, a less complicated wiring harness, extra built-in software program, fewer surprises when one thing goes improper and different issues don’t work correctly, or one thing bizarre begins occurring.”

Wright supplied a sensible instance of how the hodgepodge strategy may end up in a crummy buyer expertise. “My 2008 Volkswagen has bought a pleasant shade LCD proper there in the midst of the instrument cluster and it drives me loopy, as a result of there’s loads of room to have a number of data on there, however they’ve divided it right into a bunch of massive fields. One of many fields offers you the skin air temperature—till the low gas warning goes off. When your low gas warning goes off, they overwrite the temperature with the low gas warning icon and till you set extra gas within the automotive, you possibly can not inform what the skin air temperature is.”

“They may so simply have moved stuff round and put that some place else, however they couldn’t try this as a result of the best way they developed issues, there was a selected crew that did that, a selected piece of code—it’s executed this manner. That’s the form of factor that Tesla will get proper of their sleep, and the large guys actually wrestle with.”

The built-in strategy additionally signifies that, as expertise improves, issues could be upgraded rapidly and easily. Within the conventional auto trade, enhancements are normally made solely with every new mannequin yr. A smartphone maker, then again, may roll out an improve, or perhaps a main new function, in a matter of weeks.

As we’ve seen, Tesla has made a number of necessary upgrades to its automobiles remotely, with out the house owners having to do something. Making related adjustments to a conventional car would require bringing it again to the seller. So far as I do know, no different automaker has ever issued an enchancment or improve for an current car, besides to repair a defective element.

In an EV, electronics and software program are the very coronary heart of the car, in order the majors start to supply EVs, they may finally be compelled to undertake a extra systems-oriented strategy (though this isn’t prone to occur so long as they’re merely adapting gas-powered fashions by dropping in an electrical powertrain). Moreover, two different highly effective traits are converging with electrification: automation and connectivity. Maintaining with these advances will completely require a software-centric strategy.

That is no minor adjustment for the automakers—it’s a revolution in the best way they design and construct their merchandise. To construct the electrified, autonomous, hyperconnected vehicle of the twenty first century utilizing the present system can be like constructing a smartphone that includes one chip and working system for telephony, one other for the web, one other for the digicam, one other for the music participant, and many others.

It’s not only a query of doing a greater job designing the electronics and software program—the issues are inherent within the construction of the trade. As Wright defined to me, regardless that the majors are enhancing their software program techniques, “they often don’t develop any of that stuff themselves, they write a spec they usually ship it out to Tier 1 suppliers like TRW, Siemens and Bosch [or, in the case of the Chevy Bolt, LG Chem]. In the event that they’re nonetheless doing it that approach, I feel they’re nonetheless going to have an issue.”


Written by: Charles Morris; You’ve simply learn an excerpt from Chapter 9 of Tesla: How Elon Musk and Company Made Electric Cars Cool, and Remade the Automotive and Energy Industries. The remainder of the chapter discusses Tesla’s battery improvements, the origin of the Supercharger community, Tesla’s security options, Autopilot and extra. The next chapter explains how Tesla redefined not simply the car, however the automaker.

The e-book has been utterly revised and expanded, with the addition of latest chapters on China, Model Y, Cybertruck and the occasions of 2020. It’s now obtainable on Amazon.
