Thank you every one about the knowledges on the transmission. So only the evolution MR does have dual clutch and 4 doors.

 

I'm not sure if the transmission in the 3is behaves the same, but we can downshift in the isf pretty quickly. If we are cruising in sport manual mode in 8th gear for example, we move the gear shift right and pull the down paddle shift. That'll drop you to 4th or 3rd gear almost instantly. Then we move the gear left again. It's one more step than a dct but it's pretty easy to do.


This is mostly right except the part about the pause and the making it feel like a manual transmission.

 

There is the M3 sedan, Audi S4, Merc CLA, and a bunch of others.

 

I see I am a lone fish in the sea.....still trying to explore my options. But those mentioned above....is well beyond a set pocket for a DD

Thanks for the extra info

 

There are several DCTs on the market now, each of them with a different "personality." For example, most people hate the DCT in the Focus because it's generally clunky and never in the right gear. VW / Audi DSG requires expensive fluid changes and has had it's own problems. BMW SMG... terrible; I dont know how the new one is.

I dont think this car is "raw" enough to really require the DCT... The DCT in most of these cars is more about marketing than it is about actually performance benefits.

 

the smg isn't even a dct, it's a single clutch system. the dct is far superior and smoother. BUT i am not saying it's good, it still got its own problems

 

Forgot that about the SMG, but my comments were generally toward non-conventional (non torque-converter) automatic transmissions. I understand chasing this idea for the M5, M3 or IS-F but 200 and 300 hp cars don't require it.

 

i personally agree as well. even when they put dct in the 335 (i think it's a specific package) i didn't think it's really that necessary

 

The new IS does the same if you throw it back into auto, punch it, then back into manual. It drops to 6th first, then to 4th, all within 1.5 seconds but not right away into 4th. Not sure what you mean by pulling the paddle in auto. That takes forever. Could you elaborate on that please? What's the difference if you do that in manual mode? Mine, in manual mode, if you drop it from 8th to 4th quickly, it'll take forever to go thru all the gears. First it drops to 6th, then there is a slight delay, then to 5th, delay, then finally to 4th. By then you're already over it. it's quite pathetic to watch...In auto (D) mode that happens quickly and it skips 5th, which I don't get at all. I drove an ISF yesterday for the third time and was really impressed with it (again). The tranny is just like in the IS, but it just feels quicker when it shifts. The downshift from 2nd to 1st is the jerkiest i've ever seen, with no rev matching at all. It actually throws you forward. But the sound and torque...The startup alone made me question my choice of car. Also the downshifts are much nicer. It's almost like DCT, drops gears nearly instantly with perfect rev matching, there is no hesitation. I was actually a bit depressed when I got out, thinking my IS will never be as sharp. That's right up to the point I got back into mine and it just felt great. I realized right away that I needed to do two things: stop spending so much time in eco mode; get a new exhaust. Then it has a chance to be as pleasing as the ISF. A stock IS sounds like a speaker box inside of 10 carton boxes. Way too civil.

 

The difference is that in sport manual mode the transmission downshifts gear by gear when you pull the downshift paddle. In sport auto mode the transmission skips gears when you pull the downshift paddle. At least that's how it works in the isf.

 

I agree. I have both transmissions and in my experience the 8 speed is smoother and the 6 speed feels more aggressive in sport +. As for their shift times they both shift very quickly and neither is noticeably faster than the other.

 

There is no sport + mode for the 6 speed transmission.

Also Lexus markets their 8 speed DIRECT SHIFT transmission as one of its best designs ever, even if you can't feel the shift differences between the two transmissions.

 

This is not correct. The 350 AWD F Sport does indeed have Sport +. The difference between Sport and Sport + is the AVS settings, and nothing to do with the transmission.

 

That is correct, the F sport I test drove did have Sport and Sport +

 

I don't buy it. ZF uses the same 8 speed in both RWD and FWD configurations.
