The latest episode of Munro Live covers Sandy Munro’s mockup of the VW ID.4 Battery prototype coming from the work we have done with Sabic.
In this episode, Sandy goes over some of the ideas behind creating a practical battery system that will work best for this vehicle, taking the best ideas and attributes of other battery systems we have analyzed.
From keeping the cooling system architecture of the ID.4 but instead building it into the new composite body of the battery housing to the connectors, borrowing load bearing and structural ideas from aerospace projects that we have worked on in the past, comparing larger battery cell designs that are glued to the battery box that actually provide more space for additions and more.
In this fascinating long-format episode, Sandy along with John Waters (Technology and Innovations Leader) from Sabic begin by telling stories about the EV 1 battery tray which both of them worked on in the past. Sandy talks about how the OEM slowed down the process and caused Delco, where John used to work, to jump through several prototype hoops which were unproductive, but eventually the Lean Design, weight-reduced and fire-retardent superior design was chosen.
Moving on, the group meets up with Dave Sullivan (Leader, Americas Automotive Marketing as Sabic) and they walk through the new project and discuss the combined efforts of the group (over 40 people total) who came together for the Munro Sabic and VW workshop as well as suppliers.
The episode then winds through the innovation workshop and highlights the findings and process that culminated in a 53% weight reduction of the battery tray. If you are a product design engineer, you don’t want to miss this episode. Click below to watch the full video:
Munro Does A Teardown Analysis Of The Volkswagen ID.4 Electric Motor
As Sandy points out at the beginning of this video, it is basically unheard of that a company would give us one of their products and permission to teardown and analyze it on our show. Most of the time Munro performs teardowns for companies in private with the data owned exclusively by them, or we choose to teardown a vehicle or product independently in order to sell the information to anyone if we think the technology is interesting or unique. But in this case, Volkswagen has given us permission to walkthrough the process of tearing down their ID.4 Motor on Munro Live.
VW modular concept design regarding the electric motor, housing, bearing shield, inverter and gearbox, allows them to take the ID.4 motor and stick in pretty much any suspensions system to adapt the motor to a variety of vehicles in their fleet. Most likely this choice is made so that they have agility to convert other non electric vehicles to electric in the future. This is a very smart business choice and shows that VW has a keen eye for thinking about their global market reach and creating flexibility.
Sandy points out comparisons with Telsa and other motors we have studies, but the real focus is on pretty much every single aspect of the ID.4 motor itself. If you have ever wanted to know anything about the ID.4 Motor, this 30+ minute video probably covers it, with the exception of cost and certain performance data.
For a very illuminating video that is sure to please a VW fan or EV enthusiast alike, watch the video below:
In this episode of Munro’s teardown of the VW ID.4 battery pack, Sandy talks about all of the battery design that he likes and doesn’t. This teardown is done in partnership with SABIC to develop a pack that is constructed out of thermoplastics.
3IS Comes to Munro to Discuss Comparing Tesla, Ford, and VW’s Electrical Architectures
In this long format, podcast-style episode of Munro Live, Sandy and Dave Warner from Munro spends just over 40 minutes discussing the electrical architectures of the Tesla Model Y, the Ford Mustang Mach-E, and Volkswagen’s ID.4.
3IS researches automotive electronics and electrical systems, creating databases on the main EV systems including Body Electronics, Infotainment, Navigation,Telematics & Connectivity, ADAS / Safety, Automated Vehicles, Chassis Control, Powertrain, EV / HEV, and more.
The discussion first starts off with introductions then moving swiftly into comparing the number of ECUs in the vehicles, number CAN Buses, ethernet usage, LIN Buses, usage of LVDS Channels, audio and the pitfalls of “parts-bin” engineering, usage of fuses and relays. Finally, the team talks about the specific architecture of the ID.4, the Model Y, and the Mustang Mach E, diagnostic systems, and ultimately which system the team thinks is best, covering all of the plusses and minuses.
If you are truly interested in the nitty-gritty of EV electrical, then this is the episode for you:
2021 Volkswagen ID.4: E6 – Wrap Up with Alex Guberman
In this episode of Munro Live, Sandy turns the tables and interviews Alex Guberman from E for Electric on his thoughts and experiences with the ID.4 which he will be receiving soon.
This video starts off with Alex explaining he just slept on the floor of his newly purchased house in Las Vegas which doesn’t have any furniture yet.
Alex has just recently moved on from driving a Tesla for many years, but admits that owning a luxury Tesla is expensive. This is the main reason he bought the Volkswagen ID.4 which comes in at about $30,000 USD and he feels that the ID.4 is best for that price range.
Want to know all of Alex’s and Sandy’s thoughts and research on the car? Well you will just have to watch the episode:
In this video, Sandy talks about the ride and drive experience in the Volkswagen ID.4 and whoa does it get a little crazy.
Sandy starts off backing the car out of the loading bay at Munro and he is pleased with the performance of the rear camera assistance. However, from there, Sandy tries to set the navigation to see how the autonomous driving performs in the ID.4 with the goal of trying to get to a charging station. This winds up not going well.
It should be noted that Sandy was also in a rush to complete this trek and then get back to another meeting, but the hilarity that ensues during his travails with the UI/UX of the Navigation system is priceless.
But we will let you decide what you think. Watch here:
In this hilarious episode, Sandy encounters some of the frustrations you can experience at one of the Electrify America charging stations with the VW ID.4.
As this is very much a video-only experience, we won’t recount what happens, but after that Sandy discusses his views on the multiple proprietary plug situation at charging stations and reveals that a tech installing one of these charging stations says that it takes twice as long to install an Electrify America station as it does a Tesla.

2021 Volkswagen ID.4: E3 – Hoist Review, Front and Rear Suspension
In this episode of Munro Live Sandy conducts a hoist review and has a look under the car examining it’s structure, suspension, as well as brakes and other exposed/visible parts from underneath the vehicle.
First Sandy removes the aeroshields so that he can inspect the underbelly of the car. Sandy remarks that he finds, ” there are cross car beams all over the place,” and is a little surprised at the over engineering displayed here. That being said, perhaps this plays into VW long history of making very safe vehicles, but it seems a bit much to Sandy’s keen eye. Sandy, being the father of the Lean Design methodology, always teaches that part reduction and design simplification is best when creating a product, especially a new vehicle platform.
Moving on to the suspension, Sandy finds a coil spring over a shock absorber with a stabilizer. This would be the general configuration of a more economy-priced vehicle. Sandy points out that this is in contrast to what you would find in a higher end vehicle such as a BMW or what we found on the Tesla cars we have torn down.
Sandy goes on to show of the steering mechanism/box, he explains why European cars all have pass-by shrouds, why the rear wheels have drum brakes, and much more. To get the full Sandy analysis, you have to click below to watch the full episode.
In this episode, Sandy gives his impressions on the use of the Volkswagen ID.4 frunk comparing it with other vehicles Munro has analyzed, specifically the Telsa Model 3.
The first thing Sandy makes a comment of is the fact that the VW ID.4 hood is quite heavy and has to be lifted by hand unassisted by shocks – unlike the Model 3. Sandy goes on to explain why maybe the hood is configured the way that it is and points out differences between European designs and why the hood is shaped in order to lessen the damages to a pedestrian involved in a head-on collision.
Then Sandy finds that the VW ID.4 hood has a lot crammed underneath it similar to what you would find in a legacy I.C.E. vehicle (minus an engine, fan, etc.). But you will find the fuse box, which is one of the first things that Sandy has an issue with. In this VW fuse box, you do not find a schematic explaining what he fuses do underneath the cover like you would in many cars. Instead, you must look at the manual to figure out what fuse performs what function.
Next up is the bottle and hose for the windshield wiper fluid which Sandy likes, due to the blue lid making it obvious what that is for. However, Sandy finds the bottle detaches and hides perhaps a very important secret underneath.
