range gains from weight reduction?

Sun Oct 31, 2010 12:10 pm

this is an odd idea, i know. i rarely need more than two seats in a car, if ever.
reducing weight increases range in EV's. for example, i assume this is why a spare tire isn't included with the Leaf.
I have no idea how heavy the back seat is, but if one were to remove the back seat from the Leaf altogether, would this appreciably increase range?

I'm not an engineer, but common sense tells me that your range would be increased.

Now, if the car weighs, say 3500lbs; and you remove 35lbs of rear seats; you should increase your average range from 100mi to 101mi (1%) ;)

Think of how much extra range you could get from removing the battery! All that weight savings!

Weight is most impacted with weight in city driving and on any hills, reducing weight on a hill can make a significant impact on range.

A typical DieHard Group 24F battery weighs 42 pounds.
An Odyssey PC545 Battery: 11.7lbs

That's probably the easiest 30lbs to knock out of the car.

If the 12v system is topped up when on AC charge, then you can probably get away with a pretty small battery for extended garage parking.

I weight 194. I could easily weight 170. That's another savings of 24lbs right there. :(

You may have to sign a range waiver for that:)

I understand there is a scissor-jack but no spare wheel? Leave that thing home. It's a AAA towing event, or a hail-mary can of Fix-a-Flat.

The rear "deck" separation thing is just in the way, it gets a dusty spot along the garage wall.

If you don't want the rear seats, take 'em out. They probably weigh more than you think, with three carseat anchors and such.

Beyond that, you're into expensive mods.
