Munro’s ‘Tesla Motor Mouths’ Featured in IndustryWeek

In a recent IndustryWeek article, Munro & Associates CEO Sandy Munro and Mark Ellis, senior lead design consultant, have a spirited discussion on electric vehicle drives.

Sandy also shared that, unasked, he also sent Elon Musk 230 ideas on how he could improve the build of the Model 3 and make it more realistic to manufacture. “I have no clue if he implemented any of it.” His motive was avuncular, he says—he wants Tesla to succeed because it’s the only automaker doing anything innovative.

Here are some other key takeaways from their interview:

  • If Sandy had to pick only one thing that distinguishes the Model 3 motor, which is the lightest of the four and has the most output, it would be the casing.
  • The magnets in the Tesla motor are “vastly different” than the other contenders.
  • The Tesla motor is also the cheapest … they think.
  • For car detectives, the Model 3 is the gift that keeps on giving.
  • When his colleague discovered the magnet configuration in the motor, Sandy got curious, took it over to a vice and gave it a tap with a hammer to see if he could break a magnet free. The whole thing exploded.
  • The BMW motor is the heaviest and most expensive, and it has the least amount of power.
  • Telsa’s invertor/convertor—the device that takes the battery power, and supplies that power to the electric motor—is very advanced.
  • Telsa’s the only automaker that uses silicon carbide on the integrated circuit (power supply) invertors.
  • Overall, Tesla’s motor is considerably smaller and more high-tech than the others.
  • The Tesla body, “looks like a kids’ high school project,” says Sandy.
  • The Model 3 battery design is “brilliant” in its circuitry design and how simple and lightweight it is compared to competitors, but there are issues with its manufacturing.
  • Overall, Tesla’s electronics team is “like a whole bunch of Sheldon Coopers that actually get along with people and don’t insult each other.”

ICYMI: Sandy Munro Talks Tesla in China

Munro & Associates CEO Sandy Munro has talked about the Tesla Model 3 and his findings several times in the past, particularly when he’s featured as a guest on Autoline After Hours.

During his April Autoline appearance recapped here by Teslarati, Sandy discusses the Tesla’s China opportunities for the Model 3, as well as the rapid progress of large-scale construction projects such as Gigafactory 3. Munro also shared his frustration with some of analysts’ assumptions about Tesla.

“I found a new source of pain. Analysts, talking about things. Holy mackerel, where these guys get their ideas from, or where they get their information from is beyond me, but I can tell you one thing for sure. I know they didn’t tear apart one of these cars. I know they don’t really look at what it is that’s going on. I’m sure they’re good readers. Readers are leaders, but sometimes, they’re liars,” Munro noted.

Munro has experience with bad data. Emphasizing his point, the teardown expert stated that some of the assumptions being thrown about the company are flat-out untrue.

“Quite frankly, I’ve been on a few of these little shows and somebody says, ‘Well, you know, such-and-such from wherever says this.’ And I’m sitting there and going, ‘Ah, that’s not true.’ ‘Well, he said it was.’ I said ‘Oh, it’s not true.’ And then I’ll reach over like, I’ve got my books right over here. Somebody says something that I know is not true, I’ve got pictures, I’ve got numbers, I got data up the yin-yang. There’s nobody gonna argue with me, that’s for sure. And if I don’t know the answer, I got a whole 90 guys that’ll (be) happy to tell you which ends up. These other guys, I don’t know, I think it’s web searches and blogs and who knows, I don’t know. But it’s not for real,” Munro said.

Munro & Associates Measures the Paint Thickness of the Tesla Model 3

This recent InsideEVs article posed an interesting question, “What Does the Tesla Model 3 Have in Common With a Cheap Toyota Etios?”

According to InsideEVs, apart from the combustion engine and the motors, the Model 3 differs essentially from the Etios. While the latter was meant to be affordable, the Tesla is seen as a luxury car sedan, facing the likes of BMW 3 Series and Mercedes-Benz C-Class.

So how are they similar?

According to InsideEVs, they both get no paint in some areas because nobody can see it. Like the Etios, the Model 3 has only been fully painted where Tesla decided to do so.

InsideEVs reached out to Munro & Associates’ Al Steier, director of the benchmarking innovation center, for some Model 3 paint insight.

According to Steier, “We borrowed a coatings thickness instrument and took readings in various parts of the car including the strut tower for you. For your information, there is one slide where we captured the rear quarter panel. Looking at the picture, it is hard to tell as there was a lot of background reflections in it.”

You can check out Steier’s slides – which reveal the exact points in the body that lack a base coat – in the following gallery: https://insideevs.com/photo/4481339/see-the-munro-associates-measurements-of-the-tesla-model-3-paint-thickness/

Munro & Associates Discuss Elon Musk’s Big Advantage

It’s commonly agreed that Tesla’s batteries hold a solid lead in range. Repeatedly, Tesla’s vehicles have proven to offer superior range over its rivals.

So how does Elon Musk achieve this big advantage?

According to Munro & Associates CEO Sandy Munro and Senior Lead Design Consultant Mark Ellis, it “has a lot to do with Tesla’s all-electric platform and the company’s proprietary battery tech.” According to this Teslarati article, Tesla is only 16 years old, and thus, it only has a fraction of the experience that its rivals in the auto market have. Yet in the EV segment, Tesla is among the veterans, having worked solely on electric cars since Day One.

Further, according to Ellis, “One of Elon Musk’s big advantages is, basically, that the vehicle is designed to be an electric car. Musk designed every aspect of this car to be as efficient as possible.”

Why Tesla is Beating GM, Jaguar and BMW in Range

According to Business Insider, Tesla has maintained an advantage over established automakers in one key area of engineering: maximizing the distance a vehicle can drive between charges. In a recent article, Munro & Associates CEO Sandy Munro and Mark Ellis, senior lead design consultant, discuss how Tesla is able to maintain this critical advantage.

In the article, Munro and Ellis cite Tesla’s strong battery-pack design, distinctive battery-cell chemistry and efficient motors are the reasons for the company’s distant advantage.

The article shares that Munro & Associates has torn apart and examined the battery pack and powertrain of the Model 3, as well as those of other electric vehicles like the Chevrolet Bolt EV, Nissan Leaf, BMW i3 and the Jaguar I-Pace.

According to Ellis, the Model 3 has the best battery-pack design of any EV he’s examined, citing the placement of battery cells in relation to the current collectors (which connect the cells to each other) and the fact that nearly every component in the pack is glued together to reduce vibration.

Munro’s Cory Steuben Shares Secrets of Tesla and Other Leading EVs at The Battery Show

Presenting to a standing room only crowd, Munro & Associates’ Cory Steuben, account director, offered automotive engineers objective technical information about today’s leading EVs during two sessions at The Battery Show North America recently held in Novi, Mich.

During two presentations, Steuben compared EV systems integrations across car companies/vehicles and demonstrated why a vertically integrated company, such as Tesla, is leading the way and why the domestics must rethink their designs if they want to catch up.

Steuben first presented “Tesla Model 3 vs. Jaguar I-PACE Motor Insights” where he showcased two disassembled electric motors: one Tesla Model 3 internal permanent magnet (IPM); and one Jaguar I-PACE IPM.

“When it comes to motors, we see many different attempts across many manufacturers—particularly with the geometry of how they put the magnets into their internal permanent magnet motors,” said Steuben. “When you look at the ideal shape is actually very expensive to manufacture—it would be three or four sets of parabolic magnets. There is no common orientation. With the Jaguar, we see three stacked magnets, all neodymium-ferrite-born magnets which is similar to others in the magnet material. Tesla does a simple single V. We have seen six or seven variations in various forms.”

Steuben also presented “Electric Vehicle System-Level Integration Trends & Thermal-Electrical Management Synergies,” where he provided a detailed report on the system-level integration advancements that are impacting the OEM-level development of thermal and electrical systems. He highlighted system integration trends from the past and present, with a focus on the Tesla Model 3 Superbottle and integrated system.
