Yes, the milage sucks, but is comperable to similar power vehicles (V8 mustangs others...).
But, they put a gastank in for a high MPG vehicle. (Not sure but I think it is 14 Gallon).

This car really needs a 20 gallon (I would settle for 18) tank.
Any chance that a few years out, some aftermarket company might make a larger tank that might fit? (I haven't looked to see how much room is available).

Almost zero. About the only way I could see you increasing fuel capacity would be to put an auxilliary tank in the trunk between the rear towers, with a gravity feed to the main tank.

 

Too bad Mazda engineers could not have provided a larger tank so the RX-8 could easily get more than 300 miles.

Guess I have to sacrifice somewhere to get the rest of the package it offers.

 

wouldnt it cost a ton it add a extra tank?

 

The engineers probably were considering their goal of 50/50 weight distribution when the chose the tank, among the real-estate concerns.

 

that, and also overall vehicle mass: tanks are kinda heavy without fuel, and very heavy when full... you don't want to have a Miata with a 50L tank in it (pretend one could fit) 'cause it'd grossly upset the balance and performance of the car when full.

 

At $6 per gallon you have no idea how depressing this thread is...

 

$6 OMG

 

On the plus side: Britain's quite a small place...

 

Many car manufacturers are using polyethylene Gas Tanks instead of steel tanks. There is a significant weight savings when using a plastic tank.

 

how many miles does this car get?

my v6 eclipse gets 250 a tank with an intake and exhaust..

i think thats on about 14 gallons....

how are the 8s?

 

8's are averaging anywhere from 13 to 23 I think
mine is getting 19mpg

 

I get between 280-310 miles per tank.

 

Wow you must have a bigger tank then me.

My Fuel warning light ussually comes on at about 220.

Let me ask, when you guys get 280 or more miles on a tank, how many gallons then fit in.

I have yet to get more than 13 gallons, even when the warning light is on.

 

holy sh***

I normally get around 210 when low fuel comes on

 

Around 14.5 to 15 gallons.

 

The fuel capacity of the US spec RX-8 is 15.9 US gallons. See http://www.mazdausa.com/MusaWeb/disp...ehicleCode=RX8

 

Agreed --- and my statement above still stands.
