A bit premature when none of us have a car yet? Maybe. But i figured I’d get this party started. Discuss part weights, weight reduction options, etc. The weight of the stock GRC is said to be 3250lbs…which isn’t crazy heavy but it’s a bit porky for a small car. Ideally trimming it down to under 3000lbs would be a good target.
Body:
Most of the body panels are already lightweight material such as the aluminum hood,, doors are aluminum(according to press release), rear hatch is plastic, and carbon roof (at least for CE…). Nothing about the fenders being aluminum in the press release but the GRY has them so maybe.
Lightweight or modified bumper supports/crash bars might be able to cut a bit of weight, though my understanding is it’s pretty lightweight aluminum.
Wheels:
The GRY wheels are 23lbs (standard cast) or 18.25lbs (Forged BBS Circuit Edition) … I expect the GRC wheels will be a bit heavier maybe 24+lbs since they are wider at 18x8.5 (vs 18x8.0) and cast. Aftermarket 18” wheels in the sub-20lb range are available which is a great way to save some unsprung rotational weight.
Suspension:
A few pounds might be saved switching to aftermarket coilovers, though that Willing be the primary reason to upgrade to them. Maybe the aftermarket will come up with other lightweight suspension components (a-arms, etc) as well.
Interior:
This page has a good list of weights of many of the stock GRY interior parts, most of which presumably will be similar/same ballpark on the GRC. Some decent weight can be saved by depending on how much you’re willing to take out/how much livability you’re willing to sacrifice… Rear seats, tire repair kit/tools, door panels, headliner, sound system, carpet. I hope once people starting getting their GRCs, they can post weights of interior components on this thread.
Pretty popular on a lot of hatchbacks is Rear Wiper delete but it’s only like 5lbs and then you dont have the ability to wipe snow/road spray off if you drive in adverse conditions.
The battery being in the trunk is optimal for weight distribution, but its still pretty heavy…lithium batteries are pretty good these days and will save about 25-30lbs.
Exhaust:
The GRC exhaust looks pretty simple with minimal mufflers/resonators so not sure how much lighter an aftermarket system would be. But we will see what the aftermarket comes up with.
The Big Nut Behind The Steering Wheel:
I’ll say it. Some people could use actual WeightWatchers.
