kiwirock:
mudguard: The brakes did their job. But yeah in a manual you could coast down Coronet and almost not brake at all. But in a big heavy SUV then you'll have to engine brake or simply drive slower down the hill. Brake firmly, release, brake firmly, release.


Yeah you're inclined to brake harder like that though, which can push the rotors to higher temperatures than say a constant 20% brake force with ventilated discs.

This is kind of why my next car will be a Subaru Forester. I looked at the X-Trail. But I don't like the idea of towing anything on a CVT which most of them are.

I prefer AWD, but the Forester's 5-speed dual range add's a pretend low range of 0.195:1 reduction in any gear that you can use on the pavement without firking the transfer box. Great for light-medium towing, overtaking or getting a little lower on the current gear on decents where a whole gear change maybe to much like going from 3rd down to 2nd.

It's a shame CVT's aren't usually designed to pull much. In principal they'd be the ultimate tow vehicle. Instead of a pretend manual mode, I'd rather a dial that let's you set the ratio anywhere you want it from the highest to lowest the transmission allows.


I would not tow with a CVT, especially a boat as the risk of slipping the belts is too high. A pity as CVT's manage peek power very well.

I weep for the fact its getting harder and harder to find a car with a proper manual gearbox!!!! I've only held on to my 2001 Mitsubishi Galant because it has a clutch. I even had a car dealer be completely rude to me about not wanting an automatic or CVT. Things like this only strengthen my resolve.

And before I'm asked, I've owned two Automatics and frequently rent cars for work so I've driven most medium sized replacements to my dear old workhorse. The only one I might buy if backed into a complete corner would be a VW DSG.

Give me an automatic and or a CVT any day over the old technology. The only thing a manual will ensure is you visit the pump more often. The biggest issue with CVT's is people have no idea how to use them correctly.

I have a subaru cvt. You won't know it's a cvt unless you looked at the tachometer carefully.

So I know what a good one can do.

The nissan I'm afraid ... is plain painful.

My previous cars were
Wrx sti manual
Wrx manual
Honda civic manual
Honda city manual
Ford fiesta manual
Toyota ravc 4 manual
Brilliant

Camry auto (Well what do you expect from an old Toyota. Gets you places just don't ask it do anything fancy
Mitsubishi diamante auto - 1st to tall 2nd too short do it won't climb hills properly

The Tachometer is the evidence the CVT is doing its job maintaining optimum power

Mike, You want a SMG. Much better :D

As for brakes my BMW brakes have no glazed over or have any shudder and these have been braked from 200+kph on hampton downs at 100%.
I just noticed how bad the curb rash looks....

oh may i mention i've gone around the south island (for those north island people, it's full of hills and passes and treacherous roads that kills tourists every week) in most of those things - the other rotor warping i've had were the STI (was already like that so i know now what happened to it in its past life) and eventually the diamante ... 

ok better engine brake religiously from now on ... oh i won't be taking the nissan very far ... got a lecagy GT DIT :D

SMG's shift quick enough and are decent as. None of that auto feel. Fully manual with no clutch pretty much. But of course it does have an auto mode.

Yes for HD use DCT transmissions are well ahead of CVT types.

Eaton's Procision DCT's for the North American truck market have something like a million Km design life.

The first thing I always notice when someone is new to CVT's they become very conscious of the vehicle Revs and then focus on the Tachometer, they then try to intervene to reduce the revs. What I have done to teach them is cover the Tacho and turn up the stereo  and let them enjoy the drive and let the vehicle intelligence do it's thing.

I am not saying CVT's are perfect but they are good and they make driving a lot better especially allowing for lower capacity power plants, efficient fuel usage and a better driving experience for most.

Would not use a CVT to tow any substantial (family trailer OK) like a boat etc, off roading where you will need individual axel slipping or submerging the axels etc.

Forgot to mention. Have had the cvts now

Subaru - you wouldn't know it's a cvt
Honda - press foot, revs go up, instant torque given
Nissan - press electronic throttle, computer days Nash he doesn't want any. Nothing happens. Press more. Computer says let's give him all, belts start to spin, eventually the car lunges forward. Lift pedal a wee wee wee bit ... no more torque revs drop car stalls just about. *sigh ... bring back my sti!

I have to say the dealer tried to sell me a qashqai and the new pathfinder both have 3.5l engines I don't have a problem aparr from waiting forever for the belts to spin up. So maybe it's under powered.

We have a Nissan CVT at home - all I can criticise is the lack of gear change...I just find it dosconcerting that you plonk your foot down, it revs and then stays there, never changing...weird.

Compared to my Opel-based Auto in my other car, which is a traditional auto and has Sport and Economy modes & changes gears as often as the computer tells it to (it "learns" driving styles/habits), it's certainly quite an odd thing to experience.

coming to think of it my car's fine when i'm the only one in it.
but as soon as you put people in it, don't ask it to do anything on an incline. flat is great.
