Radical engine destined for other small Fiats - Lancia could also benefit from the technology
1 October 2010

Fiat has unveiled its new 500 TwinAir version at the Paris motor show.

Fiat is planning to expand the use of its new 900cc turbocharged two-cylinder motor, offering the TwinAir powerplant in three states of tune and, potentially, rolling it out into bigger models than the 500.

The first TwinAir version, in the show car, is rated at 84bhp. It will be priced alongside the 99bhp, 1.4-litre petrol four-pot whose performance it matches, while undercutting its economy by 30 per cent.

The other planned TwinAir outputs are 64bhp, which coincides with the basic 1.2’s output, and 105bhp, which slightly exceeds that of the current 1.4-litre petrol.

Fiat says the units will appear in other marques, most likely Lancia. Insiders say they are unlikely to power Alfa Romeo, Abarth or Chrysler group models.

Read Autocar's first drive of the Fiat 500 TwinAir

In a Fiat 500 powered by the 84bhp TwinAir, driving through the Dual Logic automated manual gearbox, the CO2 emissions are 92g/km (43 per cent less than those of a conventional engine of equal performance) and the combined fuel consumption is 69mpg.

The TwinAir engine is made in Poland and will ramp up rapidly to a production rate of 400,000 units a year.

It will go in the economy versions of all Fiat’s small cars. Insiders say it may be offered in the Focus-sized Bravo if customers can accept such a small engine in a big car.

This engine is a beaute!. I really want the 105 bhp high power version, but i dont know about the the car itself, the fiat 500. think i would prefer this engine in the upcoming topolino mini car.

Anybody knows when the topolino will be hitting the streets ?.

Just how efficient is this engine?

Answer - we don't know.

Why doesn't Fiat tell us what the specific fuelconsumption of the TwinAir is,measured in gm of fuel per kWH of energy delivered or similar, so that it can be compared with other power units?

I'd like to know how this engine compares with say the Toyota 3 cylinder petrol used in the Aygo, or a moder small capacity diesel. Telling me that it delivers x mpg in a Fiat 500 tells me nothing, because the fuel figure depends more on the car, its weight, gearing and the test proceedure than the engine itself. And making comparisons with the 1.4 litre reveals nothing... I mean the 4-cyliinder Fiat may be a dog for allI know, because again we have no absoloute fuel efficiency figure to relate it to.

I'd like to see Autocar get some meaningful data from some of these car companies, instead of reproducing meaningless comparisons put out by their publicity departments.

Well done FIAT its good to see after years of sub-par engines that they are leading the way in the next phase of engine development. The forseable future has to be a small turbo engine with clever valvle tech, combine this with a good hybrid/kers system to boost torque and you will have that holy grail of a family car sized engine that can do 100mpg and still have enough oomph to pull the provobial greased stick from a pig's bottom.

What I want to know is why would a pig have a greased stick in it's bottom?

And what's a provobial? Should it be ProVobial, maybe? Sounds like some kind of yoghurt.

[/quote]Is it me, but how does a 84bhp match the performance of a 88bhp engine? isn;t one measure of performance power>

It gets lonely down here in the countryside... I had better say no more, on this forum things can quickly descend into chaos!

Lets just say its one of those phrases I heard that tickled me.
