Here are the other relevant diagrams regarding CVT ratios. Looks like automatic mode is faster off the line as it maintains a lower ratio longer than manual mode.

Agree. I had to get used to this when I first got the car. Wasn't used to it taking some time for it to get up to speed. When my girlfriend drove the car she said the same thing. But after driving it for a while now I can get it to go even in auto. It's all a learning curve especially since the CVT is still relatively new.

I have had my S-Plus CVT for 1-week+, and the shift paddles and revs are fine. I'm coming from a 6-speed stick (Audi) and would be persnickety if the Corolla shift action wasn't perfect. The mpg's are great.

There is a learning curve with the CVT coming from a 4 speed Toyota Automatic. I can tell you that. I normally give it enough pedal to reach about 4400 RPM (is peak torque being at 4400) and let it carry me to the speed I want. It's not like other transmissions but has good aspects. I like it.

In D mode I treat it like a 2 speed.
I'm still playing with S mode.

I had a guy in a Chrysler 200 look over at me at a spot light with open road ahead and a 60MPH speed limit. I thought.....okay I will show you what a 2015 Corolla can do....haha.....he blew my doors off. Left me in the dust. The Corolla isn't a race car.

Ran a bunch of real world tests. The CVT is fastest in D mode. A little slower in S mode. Slowest in M mode. The reason is D mode keeps the revs in the power peak longer. These gimmicks Toyota added to simulate gear changes, all they do is make the car slower.

^^^^^Agreed with the statement above. Just tried out all modes this past week, and all I can say that Drive mode is the fastest out of all modes.


Sport mode is very useful when going uphill as you can increase the RPM range to zip through the hills.


Manual mode is just for fun. How I would use it is when I'm in the Drive mode from a complete stop, I slowly press the pedal, and after about a few seconds, I switch the shifter to M mode and you can make it feel "faster". Also a fun tool when going on the freeway since you can redline it all the way to speed limit.


Another tip: If your in drive mode, just press the left paddle shift (-) while driving and you can stimulate the same use of sport mode by throwing it to the highest gear possible. Basically, it your dash will show that your in D mode and in you press the left paddle shift, It will throw it to 3rd or 4th gear automatically so you can speed up.

I've noticed when I try to shift from 1st to 2nd, especially when the engine is cold, it won't shift at all, in terms of acting like a normal automatic or manual transmission. Once it warms up though, it's better.

I think that in the manual mode, the predefined ratios are just a suggestion, the computer can override if it's not safe to shift that way.

Occasionally it holds revs while accelerating, the CVT is probably changing ratios, but not holding them like you think they would in manual.

Also, if you're going for example 35mph in 3rd, and you switch to 4th but don't hit the gas the entire time, the CVT ratio won't change until you have your foot on the gas (cvt ratio doesn't change while engine braking)

Given all that, as hard as I have to be on this car to drive it given traffic conditions here I really question how long this trans will actually last.
Too bad Toyota didn't develop a 6 to 8-speed tranny like VW has done with the DSG. I can't handle a CVT in hilly San Diego, need fast starts and ability to race between stoplights or will get run over. Would buy the manual, but wife doesn't like it. I'm coming from a 2001 Corolla with 4-sp tranny. May get the 2016 Corolla LE 4-sp auto, or just go back to a VW Jetta w/ 6-sp DSG, or wait for the Jetta VII next year with 7-sp DSG....
