CAFE is much higher than EPA. EPA is derived from the CAFE test, but the numbers are adjusted down by a large margin. A rough estimate is EPA = CAFE * .75.

You can download a spreadsheet of the numbers here: http://www.fueleconomy.gov/feg/download.shtml
City FE, Hwy Fe and Comb FE are the posted EPA numbers.
City Unadj and Hwy Unadj are the CAFE numbers.

The TDI Sportwagen is 30/42 EPA, but 38.7 / 59.9 CAFE.
