Elon Musk Calls Munro’s Analysis of Tesla Engineering Accurate

The recent article “Tesla Cybertruck’s engineering and design might be genius — here’s why” offers an initial analysis of the Cybertruck by Munro & Associates CEO Sandy Munro. According to the author, Sandy “paints a pretty picture for Tesla.”

Elon Musk, co-founder and CEO at Tesla, noticed the article on Twitter and responded with his thoughts on Sandy’s analysis: “Munro’s analysis of Tesla engineering is accurate, both pro & con. I think he will appreciate some elements of the Model Y body design.”

So what did Sandy have to say about Tesla’s engineering?

Here’s one interesting tidbit: “Munro thinks the capital expenditure would be about $30 million … to build a pickup truck. That’s a downright incredible figure. An F-150 at 50,000 units per year is more like $210 million.”

Model Y Series: Episode 4 – Cowl Cover Clip

Episode 4: Cowl Cover Clip & Request from Sandy

Hello! This is episode four of Munro’s Tesla Model Y Performance teardown, where Munro & Associates CEO Sandy Munro discusses a potential redesign of the Tesla Model Y cowl cover clips and gives a heartfelt message about “paying it forward” amidst the COVID-19 pandemic. Let’s dive in!

As discovered in episode three, two components of the cowl cover were broken or missing. While the missing part is a quality control issue per Sandy, he does offer some insight regarding the part that failed. He noted that the joining point was very fragile and he had concerns about its robustness. Be sure to check out the full video here for Sandy’s insight on a potential redesign to address these concerns.

Model Y Teardown: Initial Observations: Regen Braking

It’s arrived! As many of you know, Munro & Associates received its Tesla Model Y Performance earlier this week. CEO Sandy Munro is currently at the Munro North American headquarters ready to dive-into the vehicle teardown. He’s already offered his first take on the vehicle, which you can find here:

Sandy has now moved onto a couple of functional/performance tests. It was observed during ride-and-drives that the vehicle demonstrates an aggressive amount of regenerative braking. Sandy wanted to get an idea of how much, so he put some numbers together.

Sandy accelerated to 32mph for approximately 101 feet, then let off the throttle (no brakes applied, coasted to a stop utilizing regen mode only). The stopping distance was measured at approximately 173.5 feet from the point the accelerator was released. (Interesting note: at the 101-foot mark, the car did briefly continue accelerating to 33mph.) In addition to the stopping distance, it was also observed that the brake light comes on during regen braking mode.

According to Sandy, “this is a nice safety feature that was not implemented on the Chevy Bolt. It should be noted that the Chevy Bolt had two modes of regen braking: the first being simply taking your foot off the throttle pedal, and the second when you take your foot off the throttle and depress a paddle switch on the steering wheel to put the vehicle in a more aggressive regen mode. The brake lights never came on in the Bolt regardless of which regen mode the vehicle was in.”

Munro & Associates Help Clarify the Tesla Model 3’s Rusty Seats

An InsideEVs article recently asked “Remember the Tesla Model 3’s Rusty Seats?” Author Gustavo Henrique Ruffo, with the help of Munro & Associate’s Director of Benchmarking Al Steier, was able to provide readers an answer, “apparently, that’s normal.”

According to Ruffo, “whenever we hear about any issue EV consumers may have, we investigate them. That is how we found out Nissan showed a $35,000 bill for a single Leaf battery pack, and PSA had comparable prices for the humble Peugeot iOn. As the biggest EV manufacturer, Tesla tends to present more issues. We dig a little deeper whenever there seems to be a problem, but that helps get facts straight. That is what happened with the Sudden Unintended Acceleration accusation against the company and now with the rusted seats on a Model 3.”

All was quiet … until Munro published its fifth segment of its “Tearing Down Tesla” series where the company analyzed the front seats of the BMW i3, Chevy Bolt EV and Tesla Model 3. InsideEVs reached out and Steier offered some additional insight:

“If you were to look at a number of seats across the various manufacturers, you will find that about 50 percent do not paint the seat supports (bottom and/or back). They will however paint any area that is visible to the customer – i.e. the lower mount points and sometimes the rails if they are not covered with trim. So most have determined that they can live with a little surface rust on non-visible parts. Besides, eliminating the paint is good for the environment.”

In sum, according to Steier, “this is not an issue.” You can check out the entire InsideEVs article for full comments and details:

Tearing Down Tesla Series Concludes

In December, we kicked off our “Tearing Down Tesla” series of articles that compared notable aspects of leading EVs using our proprietary Design Profit software.

Debunking Tesla Cybertruck Myths

A recent Yahoo! op-ed article set out to debunk some of the myths – safety, towing, weight and more – of the Tesla Cybertruck. Notably, the article cited Munro & Associates CEO Sandy Munro on one of the myths regarding the Cybertruck’s weight.

The author shares details to debunk the myth that “the Tesla Cybertruck will be extremely heavy” because it will require a massive battery pack to carry and a body made of 3-mm thick Ultra-Hard 30X Cold-Rolled stainless-steel body parts. According to the article, “it would be in a regular vehicle, not in Tesla’s pickup truck.”

According to the article, Tesla CEO “Elon Musk himself said its weight would be comparable to that of a regular pickup truck of the same size” due to its construction. To underscore this point, the article cites Munro’s comments on the vehicle’s weight and references one of Munro’s technical slides. You can check it out here:
