The Green Police Super Bowl ad provides a lighthearted take on the dizzying array of choices confronting those who want to adopt a green lifestyle and minimize their impact on the environment. The 60-second spot ends with the Green Police confirming that the Audi A3 TDI clean diesel is a green choice. The A3 TDI recently won the 2010 Green Car of the Year award presented by Green Car Journal and provides an EPA-rated 42 mpg on the highway — the highest fuel-economy number of any luxury car sold in the U.S. The clean diesel technology of the A3 TDI also reduces greenhouse gas emissions by 30%.
