The engine is also available in natural gas and ethanol versions. The natural gas versions of the motor can be specced with an additional tank on cars to extend range from 261 to 808 miles depending on size and use.
We likely will not see this motor or any variants in the USA as it will likely go into the Up! and Polo which are not currently US models. It is simply awesome from a technological standpoint to see the way Volkswagen is approaching green internal combustion motors as well as alternate fuels.
