Was not aware. Thanks. Was just looking at some of the Toyota stuff, the 4GR 2.5L V6 was heavier than the 2GR 3.5L V6. The smaller engine is heavier by 36lbs. Both naturally aspirated. Both from the GR family of motors

 

I think I know why.
Perhaps it’s because both 2.5 and 3.5 use the identical V6 block?
Hence the bigger 3.5 is more heavily bored for thinner block walls and lighter weight, despite heavier pistons.

 

It would be nothing short of insanity for Toyota or any other manufacturer to release a new twin turbo V8 in this day and age. European and American brands can do so because they've had such a V8 for years now and have largely recouped the development costs before the global push to downsizing reduced its usage. And like Steve already mentioned, having a V8 won't fix the LS's many other problems, most notably the tight cabin.

I doubt the TNGA-L platform has been able to recoup its development costs either, since it's only been used in three very low-volume vehicles: the LS, Crown, and Mirai.

 

Toyota still has a V8 diesel, in single turbo and twin turbo configurations. Used in Land Cruiser, Lexus LX and 70 truck. Has nothing to do with development costs. Toyota has multiple platforms where such an engine can be used. Toyota is the most efficient manufacturer, they have BIG money. A real shame. GM show everyone they don’t even need to make a turbo…they could do it naturally aspirated. And hand build it. Heck, Toyota is the one company saying that ICEs are not dead

 

It makes zero sense to convert a diesel engine for trucks into a gasoline engine for a luxury flagship limo. Even when both were naturally aspirated V8's, the LS and LX never shared the same engine.

 

They just released the F33A-FTV 90deg. V6 diesel, which is supposedly the successor of their 4.5l 1VD-FTV V8.

The first gen GX and second gen LX (a.k.a. TLC100) did share the 2UZ.

 

Youre listing lots of low volume models, the V8 versions of each would be extremely low volume.

Unless I’m mistaken GM is not developing new V8s…they have V8/ but their origins are pretty old.

Toyota certainly can be cheap, but I agree with them here.

 

Y'all want a "state of the art" V8, just wait for the production model of the Lexus GT3 (LFR). 🙂

 

I'll wait for the day it rolls out alongside the GR Super Sport.

 

New 5.5 is all new. Hand built as well. Uses 5W50

Even Cadillac has a 682HP engine. Hand built. Supercharged engine 6,2litre . Lexus is so far behind. Ford has a new updated Coyote V8 500hp. Look what Ford is doing for the F-150? https://www.hotcars.com/2023-ford-f-150-raptor-r/

 

🙄🙄 Fair play lol. But I have strong hopes given Lexus's odd commitment to developing the TTV8 and fund-cutting the LC to prioritize the GT3 Coupe. Seeing the LCF, LF1, GS, and GRSS cancelled is demotivating for sure, but I think Toyota/Lexus are a lot more confident in sports car development now having seen the successes of the Supra/GR86/Yaris.

 

Amazing that V8's & V12's can be so weight and size efficient compared to an in-line four.
Plus all that bottom end torque and smoothness.

However, I guess the fuel consumption & carbon emissions puts it out of favor.

 

this has absolutely nothing to do with the thread subject.

 

Are you serious comparing these two classes? I highly doubt that 2.6 is a goal for luxury sedans. Trust me 5 or less is plenty fast. But I get it for a few V8 or high way. Lol.

 

Not like the convo has been for the past 10 messages either it has quite regressed from the original topic of the comparison test.. nothing wrong with open discussion on a forum, especially if it's addressing other points brought up in the thread.
