What else can be removed to save weight?

[eTiMaGo]

you can just turn off the engine manually when at a red light, and turn it back on when you know it's about to turn green... from what the hypermiling pros say, the fuel used when cranking a warm engine is equivalent to about 7 seconds of idling... so if you're going to be idling for a while, it'll save you fuel. Of course, if you need the AC or heater, you might not be able to keep it off for long!

i'm guessing you have all of that inside a bucket or two somewhere in a landfill :)

Carpet mats front and rear, I just have a rubber floormat (it catchs snow and water and contains it until it evaporates or you dump it) on the drivers side. Plus if I ever sell it the carpet mats (and the rear seat, spare, etc) will look like new!

OP you've already done the best thing you could do to save gas,you bought the Yaris, now its about maximizing your gas savings by frequenting one of the many hypermiling forums out there and perfecting a frugal driving style.

Heres one of many

Remove all mirrors. I think it was said in the movie "The Gumball Rally" I don't care who is behind me just who is in front of me.

[why?]

you've pretty much done most of what you can do for free, and if you don't want to take more out of the car, you are looking at what you can replace to get better gas mileage.

Definitely a lightweight battery, NST pulleys are also a good thing, the stock pulleys seem to weigh a ton. Carbon Fibre lowers weight, but that starts to cost a bunch. And also lighter weight everything, but again that costs a bunch.

That plastic engine cover is not needed for summer driving. Just four nuts. 14" alloy wheels with light weight tires are a nice place to save weight, too. The benefit here is two-fold, less fly wheel and less unsprung weight(better ride). Avoid the busy stop and go parking lot highways around the city. That 427 can be nasty.

As a new member to the site, I normally wouldn't voice my opinion, but I hope people here are not removing safety components to try to save a buck on gas... I assure you your loved ones would spot you a dollar a month you'd have saved on gas if it had kept you alive...

Yeah, but cutting off all the seatbelts and removing the airbags saved almost 12 lbs. of weight.

The only seat remaining is for the driver, passengers soon get used to sitting on the floor.

Just kidding....... but if you are referring to the plastic engine cover removal being a safety issue I'd have to disagree. Other mods may be iffy, but it's still a free country, if I choose to drive without a spare or rear seat, while in theory that make the car "less safe", I can deal with the consequences. The arguement that "you pose a danger to others" is hard to fight, staying home and not driving at all will solve that.

You don't need the valve cover cover at all. It is a ridiculous addition that hides all of the ugly crap on top of the engine, and it reduces the valve train noise you hear inside the car.

How did we ever drive cars without this piece of plastic in place?

What, you actually carry passengers? As far as I am concerned, they can walk. And I didn't have to cut anything, I used the proper tools to remove the bolts attaching the seat belts to the car.

I will seriously say that airbags are iffy as a safety component, anything that has murdered people has to be questioned. In ma though I can't remove them, they don't allow it and plug in a computer to the ports to make sure everything is ok.
