You can't go by that -- journalists flog their test vehicles.You can catch the mpg for their test pilot at the 3:14 mark (14.7mpg); hopefully from extended idling during the shoot. If the RL2 is using the same 3.5L V6, we may want to reevaluate our expectations for improved efficiency. Then again, here's another recent video of the new pilot on a track where they appear to be getting 24.6, so that's encouraging.
