If it really did reduce the vehicle's weight by as much as 75 lbs and that weight was taken primarily off the rear it could reduce the 0-60 by almost 0.2 seconds for two reasons, lighter vehicle (by ~2.4%) and a slightly higher percentage (by ~2%) of the vehicles weight being over the driving wheels.

Taking out the back seats and all the junk in the trunk that isn't required (tire pump, level 1 charger, foam support, carpet, etc.) will cut about 70 pounds. It does result in noticeably better acceleration and increased road noise. I built a flat floor for the rear, which added about 20 pounds back (so about 50 pounds weight reduction), but made the rear space much more useful and appreciated by the dog.

What is "noticeably better acceleration" ? (specs, please)
i have no interest in taking out carpet foam or anything that will increase road noise. If i just took out the rear seats and left the rest would that still increase the road noise, and how hard is it to take just the seats out. the charger isnt in my car. that thing was heavy and pointless to be in the car. what would a body shop charge me to take out the seats.Nashco said:

Be warned this weight reduction strategy doesn't always yield good results. I applied this method to my 'racing snail' and surgically removed his shell to make him go faster, but if anything I've made him more sluggish.

Fold the rear seats down and the noise increase is obvious, basically the same as removing them. Try that to see if you can tolerate the sound. The seat backs remove in a few seconds once you figure out the process. You have to tilt the seat down, push the seat back towards the outside of the car, and lift the pin out of the slot next to the door. Very difficult to explain, easy to see when you do it. The seat bottom isn't worth the hassle to remove for weight only, it's a pain and only about 10 pounds.
10-60 mph acceleration reduced by > 0 % and < 3 %, +/- 1%.

The Spark EV has a 0-60 time of 7.6 seconds. 1% of that is 0.076 seconds. 3% would be 0.208 seconds. Personally, I wouldn't spend any time on mods to make my car accelerate to 60 only .2 seconds faster, especially if it made the car noisier.

I was being a wiseass. I didn't measure it. I race and hot rod many of my cars. If you add up a few small improvements in performance, it adds up to a big change that absolutely improves the driving experience...for me.
My "noisy" Spark EV is quieter than any ICE car I've ever owned.
