It's a city car, for goodness sake; low Cd wasn't a high priority in its design. You simply can't have the cutesy looks of a 500 & a low Cd - that's basic physics.

Lots of folks have reported that high speed cruising in the 500 has a substantial effect on mpg, regardless of engine variant.

Re: TA 105 vs 85 on the autostrada

To be fair, Fiat has tried. If you look at the underneath, it's pretty flat. There is the micro-spoiler in the trailing end of the boot lid (on the Cult anyways) and the little plastic wheel arch liners that poke out of the bumper by less than a centimetre.. it all makes the beast as slippery as it can be.

And of course you can wax it.. must be worth 0.1 of an mpg..

Not really, the Mitsubishi Mirage gets 0.27 in it's slipperiest spec. Fiat could have got 0.31 (same as a Fiat Ducato) if they tired. From memory the 500e is around that figure. My goal for UFI is to get into that 0.30 territory, without really changing the styling.

Re: TA 105 vs 85 on the autostrada

Pure misery?
Grief! That's a bit strong!

I think ours is pure fun at any speed.
I always have a smile on my face when I'm driving ours.

Drag coefficient?
I couldn't care one way or another. I get 50odd mpg and the car is zero VED rated too. What's not to like or to be miserable about?

Fun all the way with a 500TA.
Mick.

that means you don't drive fast enough. at 80 mph which feels much more comfortable in many other cars, i really get annoyed with the fiat.

of course at slow speed where aerodynamics don't matter things are much better

Re: TA 105 vs 85 on the autostrada

You do know that 80mph is illegal in UK?
Not sure, but it's illegal in most countries in the world.

Sorry 79. They don't prosecute you at up to 79 no? So in UK I just do 80 the whole time on the motorway when road traffic allows as I know that the indicated speed on the speedo is always a bit higher than actual speed

Why drive 80 mph if you find anything above 50 mph pure misery? Is that some kind of masochism?

But seriously, what causes the misery and the annoyance?

I have no choice i am stuck with this car for now

The fact that i feel the air resisting me so much! And God help us at 80 mph on hills i see my fuel economy go to like 20 mpg!!! On a fiat 500 20 mpg! :'(

Re: TA 105 vs 85 on the autostrada

Bad mpg on uphill roads are normal, but any uphill road will eventually be followed by a downhill road (unless you are on your way to the Almighty) and then you will see much better mpg than on a flat road.

Lol. I had a vision of 1.2 struggling on the way to St.Peter- parping and hiccuping all the way up! Thanks for that image...

Re: TA 105 vs 85 on the autostrada

The TA engines don't sound so revvy because, being a twin cylinder, there is only one firing per revolution. A 4-cylinder engine fires twice per rev. This caught me out a few times when I first got mine, and brushed the rev limiter a couple of times in second and third gear. I certainly wouldn't agree that it"s "pure misery" above 50mph. Sure, it's not as refined as a bigger car, but no worse than (usually larger) superminis I've driven.

haha yes that rev limiter on the TA is really miserable as well = ) you reach max power at 6,000 then the engine literally dies on you. at least with the 1.4 you reach max power at 6,000 then until 7,000 you feel the power slowly slowly going away then at 7,250 you hit the fuel cutoff! it gives you notice, the TA just kills you straight up haha.
