Does anyone knows the weight difference between regular 16" steel wheels and 16" alloy wheels ?
Thanks

Probably a little lighter, though OE alloys are not usually ultra-light. I bet it saves 2-3 pounds.
 
I will weigh mine (tires and all) next time I rotate my tires. I have the alloys. We'll have to ask someone else to weigh their steelies.
 
For reference, the 15" steelies on my Forester weighed 44 lbs with tires mounted, and the 16" alloys that replaced them weighed the same. The alloys were an inch bigger, of course, so more metal was offset by the lighter weight of the metal.

That's interesting. It means I can go for 16" alloy wheels without increasing curb weight. I am trying to buy the lightest possible Sienna. CE-7 passenger and LE-8 passenger are lightest (4177 lbs) in base models. Unfortunately, I can't buy a LE-8 passenger without options in my area. I have to buy minimum of RL and Option package 1. I am trying to determine how much extra weight will be added with these options. Any help on this will be appreciated.

Why is weight so critical?
 
I get great fuel efficiency with my LE, and it has package 3. I get 22-24 around town, and 27-30+ on trips.

I strongly believe weight is critical to get best fuel efficiency.
 
RAV4 has the same engine (3.5 L) as Sienna and curb weight of base model (3.5 L) RAV4 is 3527 lbs - about 15% less than base model of Sienna.
Based upon EPA estimates, RAV4 is estimated as 19/27 MPG - about 17-18% better fuel efficiency as compared to Sienna.
 
My objective is to get MPG as close to RAV4 as practically possible. To achieve this, I am trying to get the curb weight of Sienna as low as possible.

Fair enough.
 
Toyota lists curb weight for the 2007 CE and LE as the same - 4270 lbs. Wonder if it really is the same?
 
Some add-ons are indeed lighter - for instance the CE has an antennae while the LE models with the JBL sound have an in-glass antennae. Not only does it weigh less, it would also produce no drag at all.
 
You also want the most narrow tires, so stick with the 215mm section width on the 16" rims, which models you're considering all have.
 
Remove roof rack cross bars if you get those. My LE has them.
 
There may be other trade-offs to consider. You could remove the antennae from the CE model while the radio is not in use, but to me that's too inconvenient.
 
The XLE is 4310, so 40 lbs worth of options. I don't think that's very significant given the RAV4 drops some 700 lbs. So you'll only see 6% of the fuel savings the RAV4 would give you.

Another idea - you can remove the 3rd row. I've seen someone do that and build a custom shaped piece of wood as a cover for the cargo well. That's surely lighter than the entire 3rd row seat.

Hi. My 2006 Sienna CE got great gas mileage. See my previous posts. 18 months, 36,000 miles. What a fine ride for a bare-bones trim level!!! I do not have a family, drive alone 99% of the time, don't tow or haul, and love to drive, Gas in Seattle is $4.11 for regular, 30 cents higher for premium. Always used premium. I went to mid-grade 3 weeks ago, regular last week, and gave up today. Got hit hard on my trade-in value, but it was the closest to KBB value (way under NADA or Edmunds), but it was the Edmunds number for that Zip Code I used to get the 2008 Honda Civic LX I just brought home an hour ago. Once at the table, they started at almost $3,000 over MSRP. It's a tinny rice burner in a fancy overcoat. Base model. I think I can get 40 on the Interstate with my conservative driving style, so I justified it. After I unloaded the van, which has never been smoked in, driven on dirt except once, or even eaten in (honest), I patted the drivers door a couple times and walked away. First new car I bought was a Toyota in 2001, at 44 years old. Bought 4 more new Toyotas since. I'll miss that Sienna. I'll also miss ateixeira's posts. So Long.

Thanks for the update.
 
Congrats and good luck with the Civic!
 
I read that Honda may increase production to keep up with demand for the fuel efficient sedan.

I have a new 2008 CE Sienna by honshu

I have a new 2008 CE Sienna but having a head ache of keeping up with all the gas it consumes, sometimes it costs me $60 to fill from half tank and sometimes just $40, the price of gas would be +/- .04 cents. When I was driving my 2005 Corolla CE (Bless her little engine) , I would slap it down to neutral and let her cruise to the red light. I calculated it saved me an extra 30% of gas, I wonder if is the same with the Sienna, any one has experimented with this yet?
