Refresh impact on efficiency ?

[DAJA]

If the wire harness is being reduced and tow hooks deleted, will these refresh changes improve vehicle range ?

Not enough to notice in a daily basis.

I’m hoping the changes will increase desirability of OG LE configs.

It’s all speculation, but I suspect the changes will have a tiny improvement in efficiency, but nothing noticeable outside of a lab. A couple thoughts:

1. Managing to cut weight would give a slight improvement to efficiency. It also may help reduce whatever thermal issues are reducing regen breaking on extended downhills.

2. A lot of auto suppliers have been putting R&D effort into improving components for EV use. For example, I recently saw a Bosch press release that they’ve designed a new inverter for EV’s that has 10% lower energy losses. Both the quality and price of underlying components have changed since the original release.

3. Changes to the wiring harness may (or may not) improve power management of all the non-drive train components. The car may be able to run with fewer electronic components running at all times, or only turn on a smaller subset of computers when you update something in the app.

This probably equates to single-digit efficiency gains at best, but even small gains add up over time.

Here is ChatGPT reply: In the grand scheme of EV efficiency, factors like battery capacity, motor efficiency, aerodynamics, tire resistance, and driving behavior tend to have a more significant impact than the length of the wiring harness.
