Jeep Wrangler 4xe Hoist Review

Jeep Wrangler 4xe Hoist Review

In this episode of Munro Live Sandy is joined by a long time legend at Munro, David Oberholtzer (OB1) as they look under the Jeep Wrangler 4xe and tell the audience what they have found. Once again, Sandy brings up his lifelong love of Jeeps and so it is no surprise that he is considering buying another one soon, as the Cybertruck’s delivery have been pushed out until late 22′ or early 23′.

First Sandy rattles off the specs of the vehicle, stopping to emphasize that the 17-kWh Lithium Ion battery which can bring extra torque to the vehicle (an important point for Jeep off-roading enthusiasts).

Overall though, the Jeep Wrangler 4xe Rubicon has been reported to have a nice feel while driving with reduced noise and comfortable seating and suspension. Cory remarked that he didn’t hear the engine kick in once when driving the vehicle back and forth from Munro & Associates to home which is impressive.

When looking at the suspension, Dave points out that it is the same as all of the newer Rubicon Jeep Wranglers. It also has the smart bar, which has an electronic disconnect on the sway bar allowing off-roaders to keep a better connection to the terrain when encountering highly uneven surfaces such as rocks/boulders at varying heights, logs, etc. This Jeep Wrangler 4xe Rubicon also has a front camera that allows the driver to better see the terrain in front of them and make better navigation choices when confronting rugged and difficult environments.

OB1 gives praise to the engineers that designed this vehicle as they had to fit all of the suspension and 4×4 drive train components as a regular Jeep while accommodating all of the electric hybrid aspects. There is a lot going on in the underbelly of this beast.

The electronics and mostly kept within the super module except for the battery pack which is housed underneath the rear seat which unfortunately didn’t get a chance to look at in this video. Another amazing fact about this vehicle is that it also houses two electric motors – one in the front on the engine which is a motor generator unit and one inside the transmission coupled directly in the drivetrain. OB1 points out that this same hybrid with all of it’s complexities is assembled on the same line as the regular ICE Jeeps which in and of itself is amazing.

The rear of the vehicle also contains the same drivetrain and suspension components as what you would find on a standard Jeep while also accommodating the extra hybrid infrastructure. The tow package and trailer connections are the same rugged build, which makes it one of the only hybrids that we know can really tow loads that are heavy.

All in all, the Jeep engineers have maintained all of the cherished characteristics their customers desire including the ability to modify the vehicle with the packages for lifts, bushbars, etc. Our hats off to their team. As a former Jeep owner myself, I am glad that Jeep can maintain it’s brand and quality while moving into the electric sphere.

On a sad, note one of our dearly loved associates, Mark Ellis, our god of electrification has passed on. He would have loved to have a look at this vehicle as he really enjoyed pulling apart anything new. He will be sorely missed.

KIA NIRO Hoist Review With Sandy

KIA NIRO Hoist Review Munro Associates

Sandy is back in this next episode of Munro Live and he is having a look at the undercarriage of the KIA NIRO. The first thing he points out is that unlike many other EVs we’ve had a look at, this vehicle has a huge motor in the front end. Sandy’s explanation is that because the KIA NIRO was made to be a compatible body design to accommodate it being an, EV, Hybrid, or and internal combustion engine vehicle, it already gave them the space to put the main motor up-front.

Because there is so much space under the hood, KIA made a really interesting design choice that Sandy likes, where they put the AC pump inline with the electric motor, which balances shake and is more efficient. This also allows it not have to have a separate isolation and to have only a single line coolant hose which Sandy gives them a big star for innovation.

Sandy then moves further back to the half-shafts which are attached to an offset transmission as opposed to inline which we find on several other EVs. As Sandy points out, the KIA NIRO is a vehicle made for your average person and perhaps even a timid driver, not a speed demon or an off-road enthusiast. But in that vein, Sandy does find a few interesting choices such as designing out a tusk that would tear the wheel off in a SORB test or similar crash, and instead putting a LOT of iron behind the wheel in the longitudinals/rockers.

Looking back at the battery box, Sandy points out that they used friction-stir-welding to attached the bottom plates to a plate or channel above it perhaps separating the batteries. However, at other points they used TIG welding to other bolts which is a mystery to Sandy why they would do that. This leads Sandy to another mystery object which appears to be some sort of access panel at the bottom of the battery pack.

Sandy goes on to identify some other interesting features such as the spring being separate from the shock instead of over it because there is a lack of room. To accommodate for that they created a massive stamped lower control arm. The video carries on to explain some dampening characteristics and part alignment features. Sandy and the team remark that there are many design choices that remind him of 90’s, but not in a bad way, it’s just interesting to him to find those design choices in an EV.

Sandy Conducts A Hoist Review 2021 Polestar 2: E3

From the good, to bad, to just plain different Sandy conducts a hoist review of the Polestar 2 in this third episode of the Polestar series.

From surprise rivets, semi-solid forgings, and foam pads for NHV on the brakes you can follow Sandy through an Easter egg hunt of his blue tapped findings (this will make sense if you watch the video).

All in all Sandy is happy with the safety features he finds, which is a testament to Volvo’s long tradition of crash safety.  But again to see all of the interesting finds, you will have to watch the video below:

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.

 

2021 Tesla Model 3: E2 – Hoist Review & Some Cost Savings

2021 Tesla Model 3: E2 – Hoist Review & Some Cost Savings

In the second episode of Munro’s new analysis of the Tesla Model 3, Sandy walks us through a hoist review of the vehicle.

First, Sandy addresses a somewhat hidden front access cover under the car that (we think) might be for the euro towing package because you can access the internal front bumper from there.  Why this would appear on a US model, however, is puzzling to Sandy as this would add cost to the vehicle.  That being said, Sandy is very impressed with the snap fits that he finds.  The precision of the snap fits is excellent, leading Sandy to further ponder why the rest of the fit and finish gaps exist on the doors and rear trunk/lights talked about in the last episode.

Next Sandy addresses some of the conspiracies, or at the very least, accusatory comments that we have been getting regarding missing nuts on the upper and lower control arms and the like.  Sandy, however, doesn’t find anything out of sorts on the car like this and, to the contrary, praises Tesla’s suspension.

He goes on to reveal some parts that Tesla has decided to eliminate which, as the man who invented the Lean Design® methodology, Sandy is all too happy to find – discussing the cost savings of these design changes.  But to learn what he found as he crunches the numbers… well you are just going to have to watch the video by Clicking on the link below:
