Fiat: The four-fuel car

The world's first four-fuel car is available - from Fiat.

Are you a big fan of ethanol as fuel? The Fiat Siena's got you covered. Only pressed, distilled dinosaur on the menu when your automobile tank gets hungry? Pull over and tank 'er up, not a problem for your Fiat Siena. Are you getting "fuel envy" listening to your green friend rave about their recent retrofit to use Compressed Natural Gas? Pull your Siena into the queue, you can run on CNG too. Number four, well, its a bit of a stretch being gasahol--a combination of alcohol and gasoline, fuels 1 + 2. The Siena ELX 1.4 Tetrafuel does another trick too: it is smart enough to choose automatically between the various available fuels, optimizing performance and fuel economy. The system is based on a fully integrated system, and is not a "cheat-by-retrofit to grab some headlines" item. The trick is a unique engine control unit (ECU) system which manages the different types of fuel equally well.
