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:

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!

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:

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.

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.

Looks like an awful lot of work and reduction in potential use just to save a few pounds. I'm gonna shave a few pounds off myself when the time comes, by telling my "Thor" husband to keep his circus freak self out of my car.

Have you considered that some of those things, like the bumpers, may be the things that save your butt in an accident ?

Not trying to be mean at all, but even though I dont know you, Id hate to learn that you got hurt or worse because the structural integrity was removed.

In my helicopter, I cant add anything that bolts in or is permanent at all, or remove anything, without a certified inspection and lots of paperwork. If I want to add a larger cup holder for my ginormous coffee cup, it has to be done by an A&E mechanic. Most the time ots a pain in the rear, but there are reasons for it.

I know it's controversial, but the way I look at it my economical transportation option would be a bicycle or a motorcycle, and even with all what I have removed I am sure this car is more safe than that. In addition, I drive a 1974 Fiat X1/9, and it's pretty safe for it's era but I'm sure this de-bumpered Fiat 500 is safer than that too.

I agree safer than a motorcycle, but a bicycle doesn't do 70 down the highway.

Again, not giving anyone sh#t, but just wanted to be certain the potential consequences we're considered.

I ride a motorcycle as well, a Ducati, and I have been known to do a number of risky (aka stupid) things on a racer, and I know and assume the risk as well. No preaching here...

That Bumper Support is very critical for structural support to the front end.
Now that support is gone, along with the bolts holding the radiator core support and chassis rails....
that's going to be a very dangerous front end set-up.

The radiator support is held on by the same bolts that the bumper support is hung by - so some of the bolts need to be reinstalled after removal of the support. The car handles fine, even with the high inflation pressures (44 psi) and the reduction of toe in at the rear. If anything, the car feels more responsive to steering input and probably turn even better times on an autocross.

All of those core support bolts need to be installed. It connects the frame rails.

The car is going to handle like **** without the rails connected. You are going to cause the front frame rails/ suspension to flex.

Lets not fight boys. As he said, its gotta be safer than riding a motorcycle, and im sure he knows that if something cracks or bends because he removed structural support, he caused it and warranty wont cover it.

My personal concern was that he realized the removal of certain things could cause the car to not protect him as it was designed, and he clearly indicated he was aware of that. There are alot of stupid people out there who do things and have no clue the negative effects that might be caused and I wanted to make sure he wasnt one of them.

I, for one, wish him well and hope the project turns out as he hopes it will. I'd be very interested in an update when its all done, and see how much, if any, milage or performance gains he has acheived.

Well thanks to this forum's classifieds section, I bought the under 5 lb. anti-gravity battery from a member here and installed it to save another 25 lbs over the group 96 battery I had previously installed. I removed the battery tray and four bolts strapped the battery to the support that the tray was bolted onto. Total change, 26.2 lbs. (That's almost 36 lbs over the stock battery and tray)

Dont know how electrically inclined you are, but all you have to do is hook up an ohm meter to the seatside airbag plug, read the resistance, and place in a cooresponding resistor on the carside plug. It tricks the computer into thinking an airbag is in line. Your airbag light will go off. Simply remove the placed resistors to plug the seat back in when you go to sell.

We have done this with our off road only jeeps in the past to keep from having an airbag blow up when offroading hard.

Wheels will save a lot. I put 15x7 konig dial in’s on mine and it shaved about 36 pounds.

I am on the fence about what to do with the wheels and tires. I have already pulled the trigger on a set of 195/55-15 Firestone LRR tires and was originally going to use the 15x7 team dynamics wheels I have left over from my 500T. That combo weighs about 34 lbs a corner but the wheel offset of these rims (15mm) puts too much of the tire out of the wheel arch and I feel that as well as the open multi spoke design will be a step backwards in efficiency. Neither of those scenarios are very aero friendly so I'm guessing my miles per kwh will suffer.

I have a set of Pop steelies and was thinking of adding a set of moon discs to them. that combo will weigh about the same as the team dynamics and it might look really cool. I also really like the roosevelt replicas I have on my X1/9 too - but autoricambi.us no longer sells them :(

Here's a pic of my gf's old 500 Pop with the roosevelts (and my X1/9 in the background) and the TD wheels I now have are the ones that used to be on the red 500T behind her car.

Another light wheel I like (and wish I still had) was the Rota Shakotans I left on my '12 Pop when I traded it in for the turbo. I think they would look killer and are a great compromise in the style/weight/aero departments.

If you wanted to go absolutely bonkers with light weight wheels the ultimate would be forged Ray's Wheels from Japan. They have an eco specific wheel:

https://www.rayswheels.co.jp/products/wheel.php?lang=en&wheel=SUPERECO

The 15" is 9lbs! They only list it as a 5 lug, but from what I've read they'll do custom stuff some times. They're about $375 a wheel at current exchange rates though!

I'm too much of a cheapskate to go to that kind of extreme on pricing. I found a used set of Konig Rewinds and pulled the trigger on those today. 120 mile round trip later, turns out they have a 20mm offset so they are only slightly better than the 15mm offset TD wheels I had on my red car.

So... back to the hunt and I found what I think might be the perfect set... some traklight wheels in 15x7 with a 30mm offset. That should put them exactly flush with the fender top and the wheel weight should be a good 5 lbs lighter per wheel than the stockers.

I am going to have one doozy of a garage sale once I'm done - so far it's a set of white 500e seats, a set of TD pro race wheels, some oem 500e wheels and tires, and now a set of konig rewinds to boot!

True but I hope to minimize that with a lower resistance tire in conjunction with the lighter weight wheel.

For the most part, I'm doing the tire and wheel change mostly for appearance, but I think with a tighter fit in the wheel cavity might help offset the drag created by a slightly larger footprint. And the footprint increase is arguably nil. Compared to the stock OEM firestone firehawk tire, the tread width of the firestone fuel champion tire is within 1/16" of it, and has more rain grooves meaning less rubber actually touching the tarmac. The 195/55's I've chosen have a relative narrow tread with a rounded sidewall, which I'm hoping to negate the shape a bit with the 7" rim, much like the OEM 6.5" rim does in the back with the original 185/55's. The only thing I cannot fix aerodynamically is the wheel openings and the rim lip area and that I'm giving up due to aesthetics. The only fix I see there is fitting a flat disc wheel cover over the wheel to make it flush and I'm not willing to go that far at this point (never say never, right?). Once I have the tires and wheels secured, I might try running a week of commutes with the new meats then put the old ones on and gauge the difference.

In addition, I plan on lowering the car an inch and putting spats in front of all four tires much like what can be seen on many newer cars to improve their aero numbers.

Where did he say that? hjz911 only has 20 posts and I looked at all of them. Only a comment that the new battery didn't come charged up.

I can some real world experience now with the antigravity battery - I bought hjz911's battery and put it in my car. I've had the battery discharge to the point of locking the keys in the column twice now - once while listening to the radio and having the hatch open for about 30 minutes, and another when I did not put the car on the evse for 3 days. The battery just does not have a lot of reserve capacity. :(
To solve this problem on my end, I'll be putting a small solar panel charger in the car when it's left stationary for an extended amount of time.

But I think the better compromise between weight reduction and usability for many out there will be to fit a garden mower battery like I did on my Abarth. It's not under 5 lbs like the antigravity battery, but it's less than half the weight of the stock almost 39 lb battery.

A small update - the 500e has still been doing commuter duty for a couple weeks with the new wheels and 195/55-15 Firestone Fuel Champion tires. Weight wise, the new wheels and tires come in with an additional 8 lbs weight savings, so with the current setup of removed passenger seat and oem driver's seat I am 189 lbs lighter than where I started.

Also, I'm happy to say that the wider tires and lighter wheels do not seem to have disturbed the range - in fact I may have picked up an additional 0.1mi/kWh. Last week I had a couple days where I traveled the 40 mile commute and arrived home with over 60 percent of remaining battery.

Could this mean I might be able to achieve a true 100 mile range??

Weight wise, the new wheels and tires come in with an additional 8 lbs weight savings, so with the current setup of removed passenger seat and oem driver's seat I am 189 lbs lighter than where I started.

Also, I'm happy to say that the wider tires and lighter wheels do not seem to have disturbed the range - in fact I may have picked up an additional 0.1mi/kWh. Last week I had a couple days where I traveled the 40 mile commute and arrived home with over 60 percent of remaining battery.

Could this mean I might be able to achieve a true 100 mile range??

So with 200 lbs weight reduction how much did you range increase?

Yeah, I'm interested too. Any update?

I'm back on the hunt (sort of). Buzz is about ready to start accepting more mods. At this point, compared to where I left it, I've re-installed both front seats, replaced the track-lite 15x7 wheels with some Avid.1 15x6.5 wheels, and mounted a bracket to secure a U1-R lawn tractor battery for 12 volt duty.

Weight wise, the wheels are about a pound lighter per corner, but the oem seats put about 40 lbs back in and the U1-R battery is about 12 lbs heavier than the antigravity battery. So, 189 - 4 + 40 + 12 = 141 lbs lighter than stock. For my 40 mile commute, I am using anywhere from 44 percent to 50 percent of the battery.

From this point, I think I'm going to add tire spats and some underbody covers to smooth things out.

I'm big into weight loss also on my 2013 Sport. Rear seat delete, Rota light weight wheels ( dropped 30#), AntiGravity battery ( dropped 30#), rear wiper delete (dropped 2.9 #), deleted spare tire kit ( about 40#), removed OEM air filter/ engine cover ( about 10#), replaced OEM exhaust header/ cat converter (5#), Cypher Racing seats (50#)and MPX underdrive pulley ( 1.5 # I think). I plan on a carbon fiber hood later. I was thinking about replacing the bumbers with custom made aluminun ones and removing the rear speakers.

When I got to the headers I realised you are talking about petrol driven 500, not Electric one.

You can lose 18lbs in the front and 14 lbs in the back if you pull out the metal crash beams behind the bumper cover. Just make sure you re-install the front bolts because that secures your radiator support to the frame as well.
