Next-Gen Lexus LS Rumored to Drop V8

I'm agreeing with super & SW15LS on this. And I-6 is optimal for smoothness, simplicity & luxury (feel, performance, robustness). However, from my automotive engineering background, I will add that due to the discussions I was actively involved in (all manner of vehicle planning, but not on the LS, but it's the same direction for the most part), I'm going to go and say that the MAIN decision NOT to use an I-6 versus a V-6 is packaging. It is a space savings (length) to use a V-6 versus I-6. And V-6's can move back further toward the cabin to enhance ride and handling. There may not be a hugely substantial difference in the ride and handling between an exact car with an I-6 versus V-6 (assuming both optimally placed under the hood). But there is a difference. And when shooting for all the best attributes, a V-6 packages better. The hood length can be shortened, etc. Lots of advantages / disadvantages either way. But ultimately, the issue comes down to packaging. This was my observation. If I had my druthers, I would take an I-6 (versus V-6).
Good sounding v6's, even though they are not my favorite config. I'll admit they sound beautiful: 350z and the NSX twin turbo v6

Thats actually not why they use cloth. Tastes in Japan are different than here, and while its changing they actually find velour more luxurious than leather.
Back to the V8, Like I said I don't min d a standard turbo V6, thats the typical setup in the segment nowadays (the LS and the S Class are the only ones left with a standard V8), but there should be a V8 option...especially since they just have that V8 in the LC, GS-F, RC-F lying around.

Back in the day Mercedes had 4-5 engine options for the S class, at one point S300, SD350, S420, S500 and S600 models were available here. It was in 2000 that the sixes and the diesel were dropped; and the second V8 was dropped in 2007.
Lexus has been able to get away with a V8 because the fuel economy is usually better than the competitors; and because they have Toyota to help them bolster their CAFE standards. So there's no need for a 6 cylinder model. MB and BMW don't have a mass market brand with more efficient engines to help them out so there's an incentive to sell a more fuel efficient model even if the take rate is low. Most of the A8s I see for example are the V8.
That said Mercedes is returning to inline 6 engines after almost 20 years of V6s; maybe Toyota will follow suit? The challenge is that the V6 is good for FWD and RWD while Mercedes only has to support RWD with their 6.
A V8 will be available. Maybe more than one? I've heard rumors of a 4.0L TT V8 from Toyota.

2. Au contraire. I will say the 3.0tt cadillac's engine's lag is not as overt as others, though it's there...but certainly not as minimized as, say, a Ferrari California T or 488...yet as somebody already said, the best way to mitigate turbo lag is to:
a. add electric motors
or- another option:
b. add supercharging along with the turbos (see Volvo's new pint-sized 4-cyl. drive-E engine as an example)

I could maybe forgive the sin of a twin turbo inline six instead of a V8. I simply love the sound and inherent smoothness with an inline six engine. The 2JZ-GE(no turbos) in my SC300 is just insanely smooth at all rpms, idle, 3000rpm, singing along at the 6400rpm redline, there isn't a single vibration that enters the cabin. For something made in 1992 it is way more refined than any of the 4 cylinder luxury cars on sale now. I also love how some of that great sound from the engine enters the cabin, it isn't obnoxious, but man does that straight six sound glorious, it isn't that v8 NASCAR sound, but the 2JZ sound has its own hum that is kind of hard to describe.
Now a V6, that is just an inherently unbalanced and just "BAD" sounding engine.

And again this could be for other markets. Mercedes and BMW sell the S and 7 series in many engine configurations in Europe. You can get them with the 2.0L turbo 4 if you really want or the 2.1L turbo diesel.

Have we already draw conclusion before we even try the new thing?

As the saying still goes today, "there's no replacement for displacement".
If a V12 option was available for the LS, I'd get that!

A ambiguously gay duo reference. Back when SNL used to funny.
