Yes sir, I have Lexus insiders telling me 20%. That would be big.
Did the GS 400 start this horsepower madness? Quite possibly. And it maybe a battle does not want to finish. Look at the Germans, they have 600hp and 734lbs of torque SL 65s! Exotics now are not the only high HP cars.

Finally, with the GS 450h hybrid use the 3.0 V-6? The RX 400H makes 280hp. The 3.3 liter V-6 makes 230hp. That is a 50hp gain.

If the GS 3.0 makes 240hp, and they add another 50kilowatt battery, that would be another 50hp for 290hp? That is why the GS 430 has to become the GS 460, it has to space the HP. Maybe 320 or so.
So we would have
GS 300 240hp
GS 450h 290hp
GS 460 320hp

I dunno, still sounds off. And why waste the 3.5 V-6? It ALREADY makes 280hp in the Avalon (rumored to go into the Sienna too). A hybrid off that engine is easily 300hp+

sigh...and the IS 350 may hit the 300hp rating WITHOUT any hybrid power.

We'll see!

True, those SL 65's sure do put out gobs of power, although in the SL65's case, it puts out so much power, the stock tires can't handle it all, and there's excessive wheelspin (in other words, the SL 65 should be even faster than it already is). But I think the SL65 is going over the top with power. You're never going to use all that power, unless you're on the track. I think if you have a car that reaches 0 - 60 in and around 4.5 to 5s, that's *fast enough* for all driving situations (on the track, being an exception). I see so many AMG versions coming from MB now, I'm starting to think that MB is just throwing HP and TQ at their cars in desperation, because they're not sure how else to compete.

From what I heard, the RX400H makes 270HP (230HP + 40HP electric) and 300+ lb-ft TQ; after all, the electric motors add more TQ than HP. The GS450H I think will pair the 3.5L V6 with the Synergy Drive. I'm thinking the power of the GS450H and the GS460, as the names being so close suggest , will be quite similar. I think the GS450H might be branded differently, or maybe be parallel to the GS460, but a different kind of Lexus. We've yet to find out if the GS450H is going to be the "GT" version. The GS460 will come out, and also make way for the GS350, so that power between the 2 will be clearly different. Also, the RX400H, in terms of tuning, was tuned slightly more for performance, with fuel economy benefits still being there. On the other hand, current rumours say that the GS450H will be tuned for "all out performance". It's hard to say how Toyota will position the GS460, and the GS450H. Another thing to consider is that the GS450H will appear before the GS460. Too much info is unknown to really say anything at this point.
