How to Accelerate with a CVT Transmission?

I've never had a CVT before. I know it won't be as quick as my old 5-speed Corolla. But any recommendations on how to get maximum acceleration when, say, merging on to a highway? Slow and easy pressure on the pedal?

How many miles do you have on it? The learning process is usually 500-600 miles on my corolla. The learning process dictates what your car will be set to during normal rides: eco or sport. Once the pedal goes down fully it will still only go as fast as it can. You can put the CVT into manual mode and merge quick as fuck lol Thats what I do when I need to get up to speed quickly.

Mash the skinny little pedal on the right and it goes. There is nothing special you can do to improve acceleration. Now smooth light throttle applications will get the CVT to act like they normally would (holds a specific RPM while accelerating) and this is how you get the best mileage. If the car starts simulating shift points your apply too much throttle. Play around with it and learn it. Oh and the sport button won't make you go faster ;-). That is for sportier driving dynamics only.

Don't forget to throw it into sport mode. Accelerating without it is not as fast. Try it out one day, floor it and then after a few seconds push the sport mode button with your foot down, the engine will SCREAM.

This !

There isn't really a learning curve except for your ears !
Most haters of CVTs complain about the lack of shit points, as the engine will rev steadily (the "drone effect") according to the pressure on the throttle.
The pulleys take on from there to accelerate the car.

Haters associate power with shift points.
Toyota addresed that with fake shift points but if you hear them, as luvs2drive said, you are applying "too much" throttle.
That's "too much" for efficiency, as you actually lose momentum for a brief moment each time the fake shift point comes in play (or true shift points with a regular transmission), thus lost in both fuel efficiency and power (that's the hardest part to understand for some).
But hey, if you like the sound, why not ? (and have extra fun if you have shifting paddles).>:D

Otherwise CVTs are at their best (smoothness, fuel efficiency) with gradual acceleration - not flooring - and without pushing it to fake shift points.0:)

In case of emergency acceleration, you may floor it anyway but remember it's a Corolla, not a Ferrari, so maybe you better yield to the latter:frown:...

In sport mode the transmission will simply fake-shift at higher RPM. TFLC got a whoopie 0,1s faster in that mode vs regular...

So basically just use the gas pedal as you would do with any other car. Wether you want smoothness and efficiency or "sensation", the CVT will adapt to the way you press the gas pedal.

Actually, with a CVT, you continue accelerating even when the shift point comes into play because the CVT never breaks coupling, unlike a stickshift, dual-clutch DMG, or conventional slushbox automatic.

As far as lost fuel efficiency ... I let off the throttle when I'm upshifting (downshifting is a different story, or you jerk the car around), and slushbox automatics and dual-clutch DMG's generally shift so quickly, the loss is negligible compared to the fuel the engine guzzles at 6000 RPM.

And with power, the engine's powerband is from peak torque to peak horsepower.

Not sure how high the RPM goes when shifting before the shift point comes into play because I drive a 6MT, but unless the engine will drone in the powerband without mimicking shift points, then you aren't "losing" power either.

Old thread but I have an answer for you that you may be able to apply to your Corolla (I have a 2015 Honda Fit LX CVT).

Two things you need to do....

1) Put the car in it's lowest 'gear'. My Fit has 'D' (Drive), 'S' (Sport) and 'L' (Low). 'L' gear will cause the CVT to hold 1st gear longer than putting it in 'D' or 'S'. Keep it in 'L' until you have finished accelerating. You can then put it back into 'D' or 'S' if you prefer.

2) Pump the gas pedal 3-4 times. This will cause your rpm needle to jump up to max rpm quickly rather than waiting forever for it to happen. I call it the 'Myxal Two-step' on one of the Fit forums. I found this out by mistake.

That is how you get your CVT to accelerate faster.

the CVT in the honda Fit is different than many others. Very different from the Corolla's, also. I wouldnt try this method mentioned above, toyota was quite clear on how their transmission was intended to be used.

Just. Push. The. Pedal.

You. Will. Go.

Its very simple. The CVT reacts optimally to the amount of throttle given, if you submit only 30% throttle, the RPM will just jump to about 3,000 and pull you at a rate of around 5mph per second. The amount of throttle directly effects the rate of speed increase, because as was pointed out, the CVT is always connected to the engine, meaning, more engine speed - more wheel speed. The ratios constantly change for optimal acceleration under the amount of engine load and throttle applied. If you really feel like abusing your little Rolla, punch it to the floor and watch it perform. It sounds like a really turbo fueled barn fan but it will pull you!

I personally never punch my pedal, i love my cars, driving is my favorite hobby, and cars are my prize possessions. I usually give enough throttle to get the RPM to about 2,000 or less, sometimes up to 2,500, and i found that i accelerate just fine under this standard. If i feel like getting some more spirited zoom, i can punch it a little harder and get the RPM to around 3,500, and i never intentionally go higher than that unless its on cruise control and im climbing a large Adirondack mountain on my 1 hour commute to work every day. In which case, the RPM go up to about 4,100 when on cruise, and then drop slowly to around 3,100 as it finds optimal torque ratio for climbing the mountain.

This is a very refined and well paired drive-train. I have no complaints, toyota has done very well in watching the failure of the other manufacturers and they provide us with, in my opinion, the best in class sub compact on many if not all fronts. Definitely best in class on the fronts that matter, which are reliability, dependability, fuel economy, value initially and at resale, and general performance. I have yet to find a vehicle that meets the top notch sector of all those aspects.

Go toyota!

Even if you don't put it in the 'L' gear to hold 1st gear longer, you can still push the gas pedal 3-4 times to try to get the rpm up to max rpm as quick as possible. OP asked how to make the car accelerate faster. Anytime I want to accelerate faster, this is what I do. Been doing it for 1.5yrs now with no issues on my CVT. And I race my CVT at the track frequently.

All you have to do is try it and observe the difference in how the car accelerates. Don't just take my word for it. It's that simple.

When i used to have my STi all i want on that car is to go faster and pushed to the limit whatever my funds can afford. But now with this corolla, my focus now is all about looks (have a different look than a hundred of corollas in my neighborhood) and comfort vs power since power will not benefit me during my daily commute. Sure i missed the power of my STi but im too old for that now with 2 toddlers.

Im actually getting a lot of looks and thumbs up with other corolla drivers. Lol
