Just got this message from Lexus via e-mail. What I find particularly puzzling is the talk of a 4.6L V8 in the LS600h. I am confused, as I thought we were sure there would be a 5.0L V8 mated to a hybrid electric motor????

Anyone have any insight? Here is the article:

I guess it's probably a mistake ? Everywhere else I ' ve read, including their own PR, states a 5.0 litre V8 in the LS600hL .

Yup a mistake for sure. So 408hp from the 5.0L eh? Too close to the conservatively stated 430hp for comfort. I still believe the final total hp figure will be very close to my estimated 441hp hehe.

I got the same message in an email it states 4.6 V8 with 405 horsepower do you think they may be changing the engine.

XeroK00L

Don't think so. The 5.0L V8 is written everywhere from the PR and Bob's speech to the specs listed on lexus.jp and lexus.com. This 4.6L V8 thing has to be one mistake Lexus's marketing dept. made.

But I wish the 505 hp was the truth revealed!

yeah i think it's just a typo, it should be 5.0L, they said it in the first debut press release, that's not something they wanted to mistake on.

so the hybrid *only* adds like 20hp? come on

from press releases like this. The 600hL of course has the 5.0 liter V8 as reported on CL. It also is the only AWD LS variant. The 5.0 liter plus the electric motors will launch this luxmobile to 60 in under 5 seconds. It will not have a gas guzzler tax but will likely have an income tax credit. It will improve the air that you breathe...It even avoids pedestrians. It's a good citizen...

Its very possible that in the 600h, the hybrid power is tuned more for fuel economy and not sport, like the 400h and 450h.

With a 405hp 5.0, the car will be quick even without the electric batteries.

LexFather

Let see, so my predictions of the 400hp Lexus were not off at all. Give me a cookie.

Now lets see
4.6 liter they said "around" 380hp.
Now an additonal .4 liters only gets 30hp, to 405?

That makes no sense from an engineering standpoint for Lexus.

Then add electric batteries for 25 more hp, for 430?

Must be tuned for economy, not performance. I think the 5.0 V-8 is maybe a 18-22mpg engine so it will need efficient electric motors to stay above 20mpg, instead of more power.

I am sure this car could hit 450hp easy in one shape way or form.

Now the crazy thing is the LF-A, it will more than likely be a 5.0 liter engine but no way an engine in a race car could be in the LS. It could not be the same engine. Not sure will it be a V-10 or V-8 either, with F-1 moving to V-8s.

And clearly, this 5.0 is going in the IS-R or whatever. It must fit. Why not a GS 500???

Dude, u should write magazine articles.

that's what i hve been thinking too, how come a 5L v8 + hybrid ONLY gets 430hp, when the ls460 already has 380hp. but then i just told myself the power isn't really shown fully in the hp numbers. we will see

encore888

Maybe the typo was 450 instead of 405 hp.
