Hey all,
Now I have been seeing tons of mixed information floating around numerous threads pertaining to whether or not the GS460 has direct injection. Considering this thread's title, I figued this would be the best one to post the information I found.
My brother is a Lexus tech and he pulled up a service bulletin for motor identification and it proves that the GS460 DOES have direct injection. As you can see in the picture below, the 1UR-FSE motor is being used.
I think there may have been alot of confusion with people mistaking the GX460 as it does have the 1UR-FE which isn't DI. Hope this clears things up for those of you that have the 460 as I know it did me. I am going to update the wiki sites as they are showing wrong as well.

If you are right I wonder why the GS has less power. I think the reason that they detuned the 1UR-FSE in the GS460 is because Lexus did not want the GS460 to outperform the GS450H or the LS460 which are both higher end models. I think with the Direct injection V8, the 0-60 would have been 5.1 or 5.2 instead of 5.4.

The times sound about right to me considering the LS is only 500 lbs. heavier with 40 more HP and 30 more torque...
Once again, because of direct fuel injection to the LS models ( our LS models are electronic fuel injection ) and our crap sulfur based fuel, our GS460's are de-tuned to 322hp. Batman is correct in his theory! Bummer
"OUR" GS460's are NOT direct fuel injection!
