Who knows, that CVT might be more tahan lasak, but you'll be going uphill with a long face.

You reminded me my old AE92 1.3 Corolla manual

That was a 1km+ long straight with very steep uphill.

3rd gear floored the throttle already, speed was dropping.

Dropped to 2nd gear continued floor it, accelerated until about 80km/h 6000rpm redline. Those cars high rpm sound is very irritating, like engine going to explode.

So shifted up to 3rd gear, and damn speed dropping again.

In the end gave up crawled at 50-60km/h until the top. Almost everyone was overtaking me. Except Kancil crawled together with me.

That time king of the road haven't release. Wonder what the scene would be? 1.5L should be fine. 1.3 probably crawl together.

BTW lest anyone forget, Subaru uses chain belt CVT whereas others uses plain steel belt.

Thus the difference in terms of durability, among other factors.

How about Nissan?

Altima (Teana sister model at US) 2.5s gave me good impression. Never check the engine torque and CVT spec, but it handle 181hp just fine.

You know being a rental car, we don't pamper it. Seems no problem to take the abuse.

Lease price is same as Camry, if the transmission is really fragile like people claim, won't the leasing company just stick to Camry to save operating cost?

Even with low engine torque, it can still climb, but it will climb slowly. When you multiply torque with gear ratio, you trade speed for torque. Unless you have plenty of torque to begin with before going through the transmission.

Hence the "going uphill with a long face".

I know very well how good CVT is with hill climbs, I've been advocating this advantage of the CVT in this forum for as long as I can remember. This is one of the reason I traded my 4AT for a CVT.

But it is not a miracle transmission, you don't get something for nothing, there is no free lunch.

Haha, a lot of people don't understand how transmission work.

Gear is a torque and speed converter like you said trade speed for torque or trade torque for speed.

On speed reduction gears let's say 10:1. Output rotation speed is 10% of input rotation speed, but output torque is 10x of input torque.

But input/output horsepower power remains constant during the torque/speed conversion if we disregard the loss. Horsepower in layman term is how frequent we apply torque. Hence "work done per unit time". The stupid wall analogy is totally misleading.

Gears multiply the engine torque to wheels.

I'm speaking from experience owning Cvt and manual trans cars. So I'm just curious why you say "going uphill with a Cvt with a long face"

I think he is referring to any low torque car as a general. With aggressive speed reduction gearing, car can always climb albeit very slowly.

Because torque and speed are inversely proportional to each other during the conversion.

10x multiplication of torque = 10x slower rotation at output. Thus the long face analogy, because of moving really realy slowly.
