Also here are some more paper comparisons. The LS500 lines up mighty well on paper compared to some of the most direct competitors.

EPA mileage: 19 mpg city/28 mpg highway
362 hp @ 5,500- 6,000 rpm
369 lb-ft @ 1,800- 4,500 rpm
2018 Mercedes S560 4Matic
4.0L V8 biturbo engine
0-60 time: 4.6 seconds
EPA mileage: 17 mpg city/27 mpg highway

I omitted most of the 6 cylinder variants of the competition because they are way too behind on power and torque. I included the Mercedes S450 because it is the only 6 cylinder competitor that approaches V8 power and torque levels.
So apples to apples comparisons here are hard. However I chose the closest competitors to list in terms of power, torque, and 0-60 times.
In this group comparison, the LS actually has the best fuel economy on paper. The 0-60 time of the LS is very, very competitive among this group. While it is down on hp with some competitors, the torque figure is extremely competitive as well. Impressively, the LS500 fuel economy on paper exceeds the slower and weaker Mercedes S450. Also despite the Mercedes S560 having a significantly more powerful engine, on paper the LS500 still has a better 0-60 time and better EPA fuel economy.
Also what an improvement the 5LS makes over the 4LS on paper.
Now we wait for driving impressions and full technical specs to come.
I just can't help nitpicking this common misconception but it's for you benefit to know: bigger brakes with more pistons won't help a normal road car stop faster because it is always grip-limited. The car can't stop faster than the tyres allow. The true benefit is less pad wear and smoother pedal feel, which benefits luxury vehicles a lot since deceleration will be less jerky.
I never implied what you're explaining. I know how brakes work. Also as an experienced student of Toyota and their history, in this case I can tell the brakes are overbuilt to take lots of abuse, to be fade-resistant, to handle extreme conditions easier, and also like you mentioned, to have less pad wear and smoother pedal feel. This is classic Toyota/Lexus overbuilt design. Brakes that can handle much more than the tires can. Uninformed observers may say there is no need for this, but this is clearly the epitome of prestige luxury. Excessive, indulgent, overbuilt brakes...even in the standard non-F-Sport LS. Lexus put a lot of time and effort into the brakes, so in any conditions (including extreme conditions) 5LS owners don't have to sweat.
I believe the hybrid here does get the F-Sport option but it won't get rear steer....
Hmm, weird then how this was seemingly omitted from the USA press briefing. You would think they'd mention this. That means the F-Sport option on the hybrid is totally region-dependent, and it doesn't get all the performance goodies available on the LS500 F-Sport.
