The 2008 Lexus GS 460 works as a good example of powertrain engineering, where Lexus took its existing GS model and dropped in the engine and transmission that it launched in the 2007 LS 460. We were very impressed with this powertrain in the LS for its fuel economy, and it loses nothing in the smaller GS 460. Of course, being a Lexus, this car also offers a very comfortable cabin with a solid array of technology, from a rich graphical interface to a superb-sounding Mark Levinson audio system. None of this cabin tech is particularly cutting-edge at this point, but it all works well. What really surprised us about this car was its performance, when we drove it for a couple of laps around the Laguna Seca race track.
