From eGMCARTECH.com on Oct 14th, 2008:
While we’ll get the Hyundai Genesis Coupe as a 2010 model year, the Koreans got theirs yesterday as a 2009 model year. According to the first few test drivers, the 210-hp 2.0L 4-cylinder model returned an estimated 26 mpg while the 306-hp 3.8L V6 returned 21.6 mpg.
