( http://www.TFLcar.com ) The new 2013 Lexus GS 450h Hybrid is no longer the speedy dragster of the hybrid world. Instead the newest Lexus hybrid is all grown up and ready for a serious job like taking you and your family to work or play. The newest and most fuel efficient GS now gets a combined 31 MPG. but is that enough to take on the German competition like the diesel version of the BMW 5 series Mercedes-Benz E class and the Audi A6. We recently had a chance to take the hybrid GS for a first drive spin around the Las Vegas desert to find out if the new 2012 Lexus GS 450h Hybrid is ready to take on  the german competition.
