Fiat 500 – Click above for high-res image gallery

Fiat has spent the last few years developing a hybrid powertrain for use in some of its smaller vehicles, such as the 500, Panda and Punto. The hybrid setup is designed to work in concert with the company's dual-clutch transmission and its all-new 900cc TwinAir two-cylinder turbocharged gasoline engine. By incorporating a small electric motor into the gearbox, Fiat believes that the combined setup can reduce CO2 emissions of its smaller cars to just 80 grams per kilometer.

The complex setup is a rarity in an entry-level vehicle, but leave it to Fiat to prove that cheap cars can be every bit as technologically amazing as more expensive ones. The electric motor can turn the internal gears of the transmission which allows it to power the vehicle from rest and add additional low-end grunt before the turbo reaches full boil. Fiat has not announced an official release date for this hybrid wonder, nor has it discussed the possibility of export, but we certainly hope that it makes its U.S. appearance sooner rather than later.

      Who cares what the CO2 emissions are; it's just more climate change religion BS. What matters is gas mileage; which isn't discussed anywhere in the article. Is this entire dribble really about how a car reduces the emission of a harmless, naturally occurring gas? Idiotic.

      Very interesting, putting a small motor in the transmission is a new way of doing a hybrid and completely wiping out turbo lag.. I wonder if it replaces the starter motor?.. can it move the car at all without using the ICE and how big is the battery?

      In any case, keep the cost and vibrations down and they may have a winner.

      Turbo charged, ICE, EV... Could you put a fuel cell in their also, I just love a car with many components, it makes it more interesting for the mechanic if something goes wrong.

      As anyone can see, it takes a whole lot of complexity to come close to the efficiency of a BEV but auto corps are happy to add complexity in order to continue to receive revenue from parts and service.

        It is all documented here. http://www.evalbum.com/1892

        I am happy to report all shipping was due to a gearbox and nothing to do with battery electric components.

        My 05 Silverado went in the shop three times and was towed three times in the first six months after being purchased new.

        How many times did the prototype ICE's of their day spend in the shop?

        They are to scared to let any FCV's out to the public. Their are a few alternatives to gas available to the public, a fuel cell powered vehicle is not one of them. Could you imagine if the auto corps would have done the same amount of studying of EV's as they did FCV's what improvements EV's would have by now.

        FCV's the best waist of money by the government to get the US off oil and the best way for auto and oil corps to make profits other than ICE's.

        EV's the best use of government funds to get the US off oil and the worst case scenario for auto and oil corps to make profits.

        It is total overkill...

        Please remind us...

        How many times has your personal EV been shipped back for repairs? And you've had it how long?

      I've been waiting for the day when a real step change car is actually available to buy... I can feel it, it's going to be soon, this year maybe, next year for sure, 2012 looks to be the big year when things really start to change and you'll find all the big mouths from the car industry telling us how clever and brilliant they were for bringing these things out at this exact price at this exact time.

      CO2 emissions are pretty much directly proportional to fuel consumption, as the perfect burning of hydrocarbons produces CO2 and water vapour - the remaining hydrocarbons are emitted unburnt or partially burnt as carbon monoxide, but only very small amounts (hybrids are very good at reducing CO and HC emissions while keeping incredibly low NOx emissions).

      Honda's original Insight achieved 80g/km in 2001; the current Prius, and the new Auris Hybrid, manage 89g/km. The Insight's fuel consumption was 3.4L/100km (or, if you prefer, 83.1 miles per imperial gallon). Please do not compare US EPA figures, these are EU test cycle results.

      The Auris should really have lower fuel consumption but to save development costs it uses the Prius powertrain - competitive acceleration in the Prius body, possibly overkill in the Auris. Fiat may well choose lower acceleration which will permit a smaller engine (900cc given above) and likely lower fuel consumption. The 1.2L Fiat 500s do 0-62mph in 12.5s (compare Prius 10.1s).

        A good measurement of a clean engine is the power generated per CO2 output.

        Prius: 134 hp divided by 89 g/km = 1.5

        Fiat 500 hybrid: 90 to 110 hp divided by 80 g/km = 1.1 to 1.4
        (hp range per wiki as there is no official 900cc ICE hp)

        Original Insight: 73 hp divided by 80 g/km = 0.9

        Citroen C4: 92 hp divided by 99 g/km = 0.9

        Fuel consumption is inversely proportional to CO2 emissions. 80 g/km CO2 would be about 68 mpg U.S. The Honda Insight was a 2-seater but the Fiat is a 4-seat car that is also much safer in a crash than the Insight. The two-cylinder 0.9 liter Multiair engine has more power than the older 1.2 liter while using less fuel, so performance should be better.

        I would estimate this Fiat would sell for two-thirds the price of a Prius. 80 g/km CO2 is quite an accomplishment in a less complex system than the Prius. I would hope Fiat offers the 0.9 liter Multiair engine in the U.S. A station wagon version of the Fiat 500 would make a great go-fer car for the Great Plains and Intermountain, where distances are great and everything is far away.

      I think this is really good is designing city cars that are actually helping with the environment. Nowadays, global warming is a big problem for society and if big car manufactures do not start contributing to improve the situation then what hope we have.
