Just as a matter of interest, what is the mpg you get from the 500, if anyone has had the chance to measure it fairly accuratelly?
Or how many miles do you get out of a full tank?

The book says 55 mpg (499 ccs engine) and I did a 600 mile round trip to Cornwall last year & the fuel consumption worked out almost exactly 55 mpg which surprised me a little as I had my foot to the floor all the way back & the engine was last rebuilt 10 years previously.

We averaged 54.7 mpg on a 173 mile trip on Sunday, in our 650 cc powered 500. The engine is still a little tight. We cruised at an average of about 50 mph, but we did vary the speed a bit.

Haven't actualy measured it. :) It doesn't seem to use much though.

MPG is largely influenced by driving style. Aside from the fact that 500s have diddy little power plants. :)

I get between 30 and 40 MPG US Gallons.

Which gives me somewhere between 35 and 48 MPG UK Gallons.

It seems as if I was getting the higher mileage near 40 MPG US (48 MPG UK) with the 499cc engine.
I think it dropped down closer to 30 MPG (36 UK) when I installed the 600 cc engine.

I haven't done any rigorous testing for quite a while though, and never really know as I do conversions from KM to miles in my head :P

exactly what i've found by fitting the 595cc engine. Car is used as a daily runner, but mainly in town, so it's stop start cituation, and it measured 35 mpg. I will give the car a long run next week, it would be interesting to see what i get.

did another measurement on a longish run and it gave me exactly 55mpg (uk). As per manufacturers data. I was curious as in some ads people selling 500's they claim 60-70mpg fuel consumption.

i think they may be getting their MPG and MPH mixed up.

hi, is that long runs, or around town?
the 35mpg was in everyday london typical traffic, stop / start.

I would doubt the reality of such a claim for "ordinary" driving.

Perhaps KPG.

There was supposed to be a mileage competition in Australia where they were taking some extreme measures to try to get higher than normal mileage.

But the first thing I'd ask is whether that is an estimate, or verified at the pump over several fillups. Or perhaps calculating it by converting from British MPG to US MPG and back to British MPG. Or, maybe just assuming a Fiat 500 could outperform a Smart Diesel that was 40 years newer.

Did a 61 mile trip (according to google maps) last Saturday and used exactly 10 litres of fuel. I make that to be 32 mpg. The journey was almost entirely motorway doing 80 km/h according to my questionable speedo.
