Drag Coefficient and quietness on the new LS460?
I know Lexus bragged about the industry low of 0.25 coefficient of drag for the current LS430.
I wonder if the new LS460 will better that number? They've been quiet about it.
Speaking of "quiet", the current LS is also a benchmark. Did Lexus say anywhere that the LS460 will be quieter? I'm kinda worried about the direct-injection knocking noise that people have been complaining in the new IS & GS engines.

Actually I remember the coefficient of drag was reported as 0.26 when the LS460 was unveiled, Xerokool had complained about it being 0.01 more than the 0.25 of the LS430UL , but it was brought up that the Cd for the LS430 is 0.26 & only became 0.25 when the UL was running lower with it's air suspension , so we may not know all the details on the LS460 yet . . .

sometimes i think it could be dangerous that it's so quiet inside the car, you don't know what's going on out there

and thanks for the note on the drag, guess lexus is still making very good use of the tunnel

I doubt the ES350 will be as quiet as the LS430 - I remember driving 03-05 ES300/330s as loaners and then getting back into my 99 GS400 and the GS seemed noticably quieter. I know the LS is even quieter than my GS. I guess what I'm saying is that if that's the case then it would be a HUGE improvement in terms of noise level, and know people are saying the new Camry is somewhat quieter but not THAT much quieter than the old one.
I kept hearing them compare it to the benchmarks that the original LS400 set, not the 430.

Maybe the engine noise just gave me a nosier perception of the vehicle. Here's to hoping they quiet that down a bit with the new 3.5L, though with direct injection there's the potential that it could just get worse. Oh well, at least I think the transmission behavior and power curve will be MUCH improved.

New drag coefficients indicate wind resistance and less..
