    My 2013 500e build - Chapter 1 - Weight removal

    Hi everyone - just bought a used 2013 500e last week to add to my fleet - this one is going to serve commuter duty to my job 20 miles from home. It's a lemon law buyback with 26k on the odometer. For starters, I clipped one coil off the top of the rear springs to make it level, and now just finished doing a complete rear seat, rear seat belts, and windshield wiper delete. That removed almost 60 lbs so far.

    What came out:



    Wiper delete:



    Rear Seat Delete:




    Total weight removed: 64 lbs, and added about 5 lbs back with the rear carpet and modified shrader performance rear seat delete. Net savings: 59 lbs.

    Next weight removal item, and I'm sure it's controversial because it's safety related but here goes... the rear bumper reinforcement. Once you remove the bumper cover, it's held on by 6 13mm nuts, and it weighs 17.2 lbs. Off it goes!





    Now my net weight removal has reached 76 lbs. Time to move to the front of the car

    So now on the front, an easy 5 lbs is the front hood insulation and the motor cover.



    Then the next likely spot to save lbs is the 12v accessory battery. It weighs 37 lbs and can be replaced with a variety of 12V batteries. I opted to go with what I had around, a group 51 Honda Civic battery (25 lbs) and a Group 96R battery (29 lbs) I picked up recemtly for my X1/9. I'm going to use the 96R battery because is fits in the factory battery mount and the cables required no modification. The Civic battery, being lighter, will work but The secure mounting of the battery and it's taller height are a potential issue.

    37.5 lb Stock Battery:



    25.2 lb Civic Battery:



    28.9 lb 96R Battery from Costco:



    At this point I've shaved 14lbs from the front. Total curb weight lost to date: 90 lbs. Not too shabby!
    Next week I hope to have enough time to pull the front bumper cover and take out some more frontal weight.

    edit: I like the lithium ion batteris but I would like more reserve capacity in the battery, I read where he drained it in less than 10 minutes with the radio and accessories on. On my Abarth, I installed a lawnmower battery with 445cca and it has worked flawlessly there. If I were up to cutting the cables on the 500e to retrofit the bolt eyes of the lawnmower battery I'd go that direction. Crazy cheap ($42 at Autozone) and weighs 16 lbs so it's a safe 21 lb improvement there.

    You do know the weight you’re starting out with?

    and what is your objective if I may ask? Your commute is only 20miles? Easily done with the standard car.

    And finally, what was the issue that caused it to be returned? 26k is a lot of miles for a lemon... sounds there’s an issue that could never be fixed?

    I'm weighing the parts removed only. I'll assume the listed curb weight by Fiat to be accurate.

    My objective is to improve the range between charges and improve acceleration as well.

    Commute is 20 miles each way - 40 miles x 5 days x 51 weeks = 10,400 miles. That's 10,400 miles on the Abarth I'd rather not do.

    Also, the Abarth uses 350 gallons approx for that year's drive. 130 gallons x $3.50 gal avg for premium in So Cal = $1225.00 in gas per year plus the additional wear and tear on the Abarth. In comparison the 500e will cost me about $250 in electricity for that same given time (house is getting solar, discounted rates from Edison for owning an EV, including a $450 rebate check for buying an EV).

    Now with a dedicated commuter car, I can tweak the Abarth now for more performance while I tweak the 500e for more economy. After all, I'm a car guy. I love to play with and modify my cars. The 500e I hope to drive for the 10 years I will be gainfully employed prior to retiring.

    As for the lemon law return, I do not know. That was at least more than 1 owner ago so I don't know how many miles were on the car when it was originally turned back in to the dealer. The person I bought it from went to Spain to study so he sold it prior to leaving. His Dad owned a car dealer and bought the car for him to use while he was here. I have not been to the dealer yet to see what the reason for the original owner turning the car back in, but I can tell you that the airbag light is on, so maybe it's related to that. I plan on doing more research to see what the details are as well as having the dealer to check for all recall being done and to do a diagnostic check on the airbag system.

    How much modification was necessary to make the rear seat delete kit work?

    The front lip that extends down to the floor needs to be trimmed and drilled to accomodate the taller floor height and seat mounting bolt location of the 500e. Also the rear section is not long enough to reach the charge cord box in the trunk area so I added a carpet to fit between the front hump of the kit and the rear box.
