Any info on the automatic transmission?

there is a Sport and Snow button aft of the AT shifter, but it's missing on the MT shifter.

Except for driver enjoyment. I've driven many dual clutch setups and none of them provided the enjoyment of actually having to change gears like a manual.

There's no doubt that the manual is a slower solution, but I couldn't care less about numbers.

Drivers with a MT don't need the transmission to let us drive in the snow.

Sorry, I had to

We could argue all day about the benefits vs disadvantages of both transmission. At the end of the day, it's all preference.

No but the TC and VSC will definitely talk to you if you start to shift a little to hard.

So because you prefer an old school manual Toyota should just say fuck it and use ancient technology for an automatic? A dual clutch system should be used in every Toyota car that is an automatic. Like I said it is a sad day when Hyundai is outpacing both Honda and Toyota.

Just because it's newer doesn't mean it's better. Hydraulic coupling has a few advantages; higher efficiency when input/output speed is not the same, aka less energy lost to starts, and theoretically less servicing required because there is nothing that is supposed to wear out.

A single clutch gearbox, torque converter or not, can shift much faster than a manual transmission. I think most people consider that adequate for a typical car, and hence there is no reason to use a more complex and expensive dual clutch system, especially considering that clutch plates inevitably wear out.

^ Bingo. Some of you people really need to learn a bit more in-depth on stuff before making statements.

With Torque Convertor Lockup like it's controlled in most cars today, there is just as little drivetrain efficiency loss as a manual. If you're comparing the auto in the FT to one in say, a 90's or early 2000's car, then you're comparing it to the wrong transmission. As other's have mentioned, the IS-F's auto tranny can shift in 0.1 seconds, much faster than all manuals (bar the sequential ones used in racing). Also, after first gear the TC is locked up right up until 8th (on the IS-F), meaning you get just as much throttle response and efficiency as a manual. I'd be more worried about the accelerator lag from Drive-By-Wire than I would be about the responsiveness of a modern TC'ed auto.

DCT's are reasonably new technology for a production car, and not something I think Toyota should be trying in what's supposed to be an "affordable", reliable, fun car.

Does the IS-F auto handle added power and track use well? I would be a little worried about heat...

[Ikaros]

Yeah, from that FR-S unveiling yesterday, I highly doubt the auto transmission is going to be from the IS-F now. I guess I'm just gonna have to buy it as an manual and hope it doesn't blow up in the process of me learning how to drive it.

You had x-ray vision? o_O

For a sports car I absolutely do, but then I've never been about the numbers sooo.. :shrug:

And Dual clutch systems are becoming less important with the newer autos. For autos, they are good. Both completely lack the feel of the manual IMO so both will be avoided by me at all costs.

They keep using words like "based on" but they don't define it beyond that. It's not going to be an IS-F trans limited to 6 gears only I'm sure. I'd bet it's a different trans all together just with similar computer tuning.

why not? the IS-F tranny isnt some magical AT. at its core, the ISF 8 speed just uses better solenoids to control the hydraulic pressure to allow lighting quick shifts. combined with the aforementioned TC lockup strategy, you get an incredibly quick shifting and responsive AT. the old school musclecar guys have been building AT's for decades. this is nothing really all that new, except for the fact that lexus had the balls to do it on a production car.
