flipside909,

Thank you very much for the excellent article, pictures and it is the 1st time I heard that 5.0L V8. I love it.

Hey Flip,

Excellent review and video. I've been reading your posts since 2005. I purchased my IS350 (one of the first in the Mid-West with ML) back in October 2005 and just love it. Now after going to Detroit and reading every single post about the IS-F, I can't wait to drive it and most likely buy it (depending on final price with options).

Anyway, my question is regarding the small read brake light inside the car on the rear deck. On my IS it's on the deck, on the IS-F it's raised, most likely due to the spoiler. It would be harder to see if it was not raised. I noticed something underneath the light... a sensor of some type. Any guesses?

Again, thanks for all the great information from you and everyone else.

The main purpose for the light sensor is actually to keep the CHMSL above the spoiler. The lid spoiler is a bit taller than what is currently offered. That sensor is also used in the 3rd Gen GS to help control the illumination of the Optitron guages in varied lighting. I'm not sure if the sensor is functional for the IS-F's guages but I don't see why not. There were no techical engineers available to ask these questions other than Chief Engineer Yaguchi-san, but he was busy talking to the Japanese press the whole time.

They'll say "no manual transmission???? Think I'll just wait for the M3, or buy a 335i now."

G head on a V block motor. A Toyota first!?!?

If the G means a 23 degree included valve angle like it has in the past, I'll be disappointed. I prefer the narrow valve angles the F heads have, and they almost always have better port geometry than the G heads. The cutaways I've seen of the 2GR-FSE have really beautiful straight ports and tight combustion chambers. I hope the 2UR-GSE is more like the 2GR-FSE than a 4A-GE or 3S-GTE.

BTW, for all the guys who think Yamaha doing the heads is something new - Yamaha has been doing performance heads for Toyota for decades.

I don't know which valve angle is better.....

All I know is the "G" always indicate a high performance motor (3S-GTE, 2JZ-GTE, 4A-GE), all the regular performance motor carry the "F" letter (3S-FE).

The IS-F got a G motor make me want it even more!

It is clear that this is the 1st high performance V motor Toyota has.

I was surprise as good as the V6 is from the IS350, it is still a F motor. And all the GS400/430 was still a regular non-high performance model.

Just keep in mind that despite the beautiful geometry of the 2GR-FSE, in the end it's still an "F" motor. Not that there is anything bad about that, but simply that the heads are designed with fuel economy in mind. G heads are designed with performance in mind.

Historically, G heads on Toyota engines have meant fuel thirsty engines with higher emissions.

But we know the IS-F will be a ULEV-II vehicle, and likely will get good fuel economy. It will be interesting to see the 2UR-GSE achieve both high performance and good emissions/fuel economy. Also, the 2UR-GSE retains the dual fuel injection system. In other words, the 2UR-GSE is the first Toyota motor ever to use G heads together with a direct injection system. My guess is that compared with the 2UR-FSE, 1UR-FSE, or 2GR-FSE, the 2UR-GSE will have higher performance direct injectors, possibly mounted at a different angle than the F motors.

Nice, thanks for sharing.
