Mini Cooper SE EV Undercarriage Analysis

Munro Analyzes the 2022 Mini Cooper SE EV Undercarriage

In this next installment of the 22′ Mini Cooper SE EV series, we introduce another long time Munro Associate, Jordan Arocha, who has been with the company for 10 years and has been a consistent provider of ideas for talking points on the Model Y and other vehicles. Cory explains some of Jordan’s background and then moves on findings they and the team have observed on this Mini Cooper SE EV.

The pair first have a look at the huge galvanized leading triangle which protects the battery behind it. This is an improvement from an earlier model which could experience damage to the battery if the car ran over something that reached and impacted the battery box. They then look at the battery box tunnel itself and find that it is basically an adaptation of an ICE architecture underbody, utilizing existing space that would be normally taken up with the exhaust system, brakes lines, etc.

The housing of the battery box is a steel stamping with robotically applied body sealer on the bottom to protect the housing from corrosion and possible to reduce NVH. One observation that shocks our group is that some of the high voltage lines are not hidden within a rail or some other structure to protect it, but instead are somewhat haphazardly tied to the undercarriage.

Moving on, looking at the K member or craddle, this large stamped steel weldment is tied into the battery pack with creates structural support and rigidity by tying the 4 bolts into the weldment. Typically we see K members/rear craddles isolated in vehicles and rarely solid mounted.

Cory finds the place where the “noise maker” of the car is mounted, sitting in the middle of the space for a spare tire underneath the rear of the car. It does have a space smaller diameter “run-flat tire” as opposed to a 15″ spare tire, but this is purchased separately.

The team then moves on to talking about the suspension which is fairly simple in nature. Then they discuss what we find when comparing European cars, how companies approach converting existing vehicle product lines to EV. Then on to the front suspension, aerodynamics, and other features we find, but to see all of our findings, you will need to watch the video by clicking below:
