Electric cars pollute too. Battery manufacturing, recycling process all producing toxic pollutant. Hydrogen engine's life is ~10 years at present.
Also it has to carry a pressurized liquid Hydrogen(safety issue).
Toyota took over fuel cell development from a company in Vancouver Canada., also owns 30%(if I remember correct) of Tesla. we hope we'll find
a better battery than current Lithium based ones for real practical electric cars. We need new infrastructure for charging stations.

I worked for a specific PUC involved in this field for 26 years, and am well acquainted with this subject. Electric cars are, by and large, nothing but a political tool, with a political agenda. Nothing more.

the new LS 500 is light years ahead of the 460 and 430 in terms of tech inside the car and engine. It will do under 5s from 0-60, trust me, I just bought the LS 500 F-Sport and use to own the 430. Plus, my last car was a c7 corvette z51 (I can get 3.3-3.6 s to 60 all day with that). The awd LS 500 gets 5.3. That's what most of the magazine are testing. Rwd are about 300 lbs lighter too. The old 290 hp v8 is a great engine but ancient. It's outdated and slower than the new Accord.

This is a stretch of a sidebar to this conversation, but I come to this particular thread with an honest question. Toyota is in the end game of redesigning the Tundra pickup, and it is rumored that the engine on the LS500 sedan, the TTv-6, is going to replace the big V-8 in the 2021 model, 3rd gen. pickup truck. I am waiting to see the reviews on the new 2022 Tundra before making a decision on the 2021 w/ the v-8, or take advantage of the better fuel economy of the TTv-6 version in the redesigned 2022 model Tundra. My question is for current owners/operators of the LS-500....in your opinion, how well will the TTv-6 engine in your sedan, make the transition to Toyota's new Tundra. I value and appreciate your opinons, and look forward to hearing from you.

The reason for the v6tt
I used to Work for Lexus and I know for a fact that the reason for the v6tt was for weight distribution. The engineers wanted the vehicle to be a mid front layout. For better handling, I believe the ls500 is 51/49 if I’m not mistaken. Can anyone guess which other Lexus has a mid front layout?

As far as turbo lag are you serious. This vehicle barely has any, full torque comes on at 2500 rpm. The engineers mated the turbo straight to the block to reduce turbo lag. It also uses full time vvti. And the water cooled intercooler helps out dramatically. If you look at the cold side tube length it’s relatively short, also reducing lag. The engine is also long stroked to a 100mm Increasing Mid range performance. Akio seems to like performance oriented sedans. That’s why Gazoo racing built that crazy Toyota Century for TAS.

I was talking to our Lexus salesman two days ago, and he was telling me about the decision from Corporate to drop the V8 and go with the TTV6...according to him it had nothing to do with CAFE standards, amazingly enough...the simple fact is that too many millennials griped & whined about the LS460's gas mileage (or lack of it) and so to capture a younger slice of the market segment, it was decided to retire that wonderful V8 from the LS lineup. And of course, yet another piece of the puzzle is the new 10-spd transmission. Both were spec'd for the sake of increasing the LS500's gas mileage. Therefore, Marketability.

That's good info bluesi808. Thanks to all for your opinion. I've looked around, and a few owners of the Tundra have installed a super-charger (Munsen sp?) seems to be a popular brand. The S.C. really wakes up that V8 motor, but does nothing (ok, very little) for fuel economy...which is my main impediment to buying a 2021 Tundra. Again, thanks for the input.

wasn't used for just weight distribution, they had to meet new cafe standards with fuel economy and the car has a better ratio than than the v8

LS460 got close to 30mpg HWY, what was the problem? That’s a good figure for any car let alone a 380hp V8 one. Most millenials aren’t buying 90k luxury sedans. Some are but most I’d say are buying minivans and crossovers much more.
The 3.4tt does have noticeable lag and it sounds thrashy and unrefined. LS needs a V8. It always held the crown as having the silkiest, smoothest one out there.
