2007 RX350 is now shown on Lexus' official website. Doesn't look like the exterior has changed, since it was already refreshed, but this is more of a powertrain upgrade. The kind BMW likes to do to keep things fresh.
Couldn't they at least bump it to 285, so between the Camry/Avalon and the IS350?
The RX350 only has 2 more hp for a total of 270hp.
How much power do you need in a freakin' luxury car!? Are you gonna race it? No. My mom's RX330 has 223hp, and that thing hauls ass. So you're basically adding an extra 50hp to a car that weighs the same. How much more do you really need?

Glaring blue HID bulbs are NOT classy, and don't make your car look nice, no matter what that kid in the Civic told you.
None, but it makes it easier for Toyota to have the cars use the same engine. And if it uses te same amount or even less than before, then why not? The MZ series is old as some people have mentioned here.

Toyota could bump all of their engines horsepower ratings, but they're more concerned about increased emissions standards (especially in California). Currently, the 2GR engines are certified ULEV-II rated engines. That's a pretty big accomplishment for the amount of power they produce.
The 2GR-FE is capable of 300hp with a little fine tuning and perhaps some more lift in the cams, and the 2GR-FSE is capable of 450hp with better tuning, cams, and an 8000rpm rev limit. Power drops off more in the regular 2GR-FE than the 2GR-FSE after their respective 6200rpm and 6400rpm redlines. The 2GR-FSE has a very slow decreasing torque band even after it has redlined, indicating Toyota held back on power output.
The 2GR-FE is capable of 300hp with a little fine tuning and perhaps some more lift in the cams, and the 2GR-FSE is capable of 450hp . . .
450 hp from a 2GR-FSE?? Naturally-aspirated? That seems like a bit of a stretch. Did you mean to type "350"?
No 2GR-FSE has even approached 350 hp to my knowledge. But, I'm willing to concede that I might be mistaken. If you can elaborate on why you think 450 hp, please do. Thanks.
Well, the Lexus dude (can't remember his position) said that they 3.5 litre is capable of more than the 306hp currently offered in the IS350. Just how much more is probably a secret.

Yes normally aspirated. I did say with cams, an 8,000rpm limit, and some really good tuning, but it goes WAY beyond that. That means you'd have to go to a standalone engine management system, but I thought that was implied. The 2GR-FSE continues to produce over 250lb-ft of torque after 6400rpm (the 2GR-FE falls off more). With more valve lift from the cams, you can stretch that to 8,000rpm, and reach around 450hp(~396whp). Granted, it will take over $50,000 to achieve something like that, but it IS possible. It might not be able to run on pump gas, either. The heads are already a low-friction, high flow design, which contradicts the usual F series heads. Practically every part in the engine would have to be replaced, and one of the piston rings would have to be removed for less friction. The oil ring and other piston ring would have to be coated with anti-friction material. Fuel management has to be extremely precise, and by utilizing the extra 6 port injectors, they can cool the cylinders if things begin to run too hot. Pistons have to be custom, high heat resistant, forged and lightweight, but extremely durable.
