I'm starting to feel like the number of gasoline alternatives we've got is getting out of hand. Natural gas, ethanol, biodiesel, ULS diesel, hydrogen. Frankly, it's all adding up to a gigantic format war...and while that might be good for the businesses involved, it's not good for the environment.
Which is why I'm excited about Fiat's Seinna TETRAFUEL. This car, marketed specifically at Brazil, can run, pure ethanol, E25, natural gas or gasoline. Of course, you can't store compressed natural gas in the same tank as gasoline, so the Siena Tetrafuel actually has two fuel tanks, just like a conventional hybrid has a gas tank and a battery.
The coolest part, however, is that the car decides which fuel it wants to use. So, for in-city driving, the Siena falls back on the ultra-efficient, low-emissions compressed natural gas (CNG). But, if it discovers that you need some extra torque for highway travel, the car's computer seamlessly transfers you over to gasoline or ethanol to provide the needed boost.
In this way, it is very much a hybrid car, but instead of being a hybrid electric, it's a hybrid CNG. They're selling well in Brazil, which has a strong ethanol and natural gas infrastructure. As new fuels are added to our bag of gasoline-avoiding tricks, I think we can expect to see Fiat's system for seamless fuel switching start to be copied. Though we should also expect that it will add a bit to the price of the car.
