BMWs current steptronics rev matches but very poorly. I find it in consistant... but then again I have very few miles under my belt on the E90... only loner miles


I was dissappointed to find out that the IS didnt rev match when you downshift. Infiniti does it... Lexus should have had it too.

 

they shoulda put that in the m5.

 

With every subsequent generation of automatic trannys claiming faster shifting and quicker response time by "miles" over the previous generation tranny, I would pretty much expect response and shift times to be negative by now, lol. Obviously a lot of this is probably a play on words or weird stats that the marketing boffins are able to cook up. BTW, rev-matched downshifting kills fuel economy too. Getting an engine to go from just over idle to 5000 rpm very quickly requires an enormous amount of fuel. Maybe it's easier on the tranny, but it's costing you elsewhere (at the pump) to make that happen.

 

I love it. I dont care about fuel consumption! I rather have it rev match than strain the transmission and feel that "jerk" as it engages. If I did I would have bought a Corolla or Matrix or Yaris or Prius or somthing.

 

What is scary is that all of these functions are so, so electronic. I am sure it is a vast improvement over standard automatic but you still lack control as the car's brain is determining what is best for you rather than the driver.

BTW, someone earlier posted that the 335's torque will destroy this transmission. Um, on what facts is that statement based?

 

Um, I think they're talking about the Lexus IS250 manual tranny and IS350 engine.

 

this is awesome
i wonder what the new M3 will be like with this auto tranny

and the new twin turbo engine with it

BMW is making good tech innovations!

 

We'll just have to wait and see how long will that tranny takes to go back to the dealership service department

 

not sure if they will have the auto for the m3?

 

probably not as quick as the camry 6 sp auto.

 

Hahahhaha what does the camry use? same as our IS?

 

camry transmissions are 5 speed not 6 speed

 

5-speed for the 4-cylinder, 6-speed for the V6

 

Can the lexus is350 transmission compete with this new tranny from BMW?

 

its probably faster than BMW tranny seeing how BMW didnt get to match IS350's numbers, even with having more torque...
