Lower emission and higher fuel efficiency, well automaker could escape it due to tough regulations not only in US but throughout the world. Europeans measure it with CO2 emissions rather than fuel economy. This adds another worry for automakers. 1999 Audi A2 was also fuel efficient premium small car but was not as successful as the car was a bit expensive.
Audi is also feeling the pressure and is going ahead with smaller, more fuel-efficient cars. 2009 Audi A2 subcompact car will be inline with these tough regulations.
2009 Audi A2 will be using the VW subcompact underpinnings with gasoline engines ranging from 1.2 to 1.8 liters and diesels. Future Audi A2 will most probably feature Quattro AWD along with an optional turbocharger.
Audi A2 will be built at the Brussels Belgium plant that Audi recently took over.
