Very very pleased


Towed my boat for the first time yesterday
I was suprised at just how well the exy towed
It was no problem to tow 1.2 ton and I felt more in control of the boat trailer than at anytime with the ford
A little sluggish off the mark, but hell, its 1.2 ton

Just a question for you regular two nuts
What is the best way to drive off the mark
Slow and easy or give a little gas to get the revs up?
When I accelerated slow and easy it felt sluggish and took quite a while to get to speed
Revs stayed below 2k
When I gave it a bit of gas it was better and reved to 3 k, but felt better
Will giving it a bit of gas hurt the exy?
Not standing onthe throttle, just a bit more
You know what I mean

Re: Very very pleased


I tow about the same weight but a Caravan.

I always tow in Auto (ie 4wd on demand) and tried manual gear selection but the cvt actually sorts out everything better if left in Drive.

I usually try to keep the revs under about 2300rpm - even when taking off.

Revving out to 3500rpm when taking off sounds normal though so its up to you.

If its Hilly then of course it needs to rev perhaps to 4500rpm.
Fuel economy is very good if revs kept under around 2500.
Much over that for long and you will see 18-20L/100kms rather than an affordable 12-13L/100kms.

That means my towing speed is determined, within reason, by the revs staying under 2300. Sometimes this means 90km/h; with a strong headwind etc it might mean (on a flat road) 70-75km/h. In the hills it does need to rev though.

80km/h used to always be the maximum towing speed but this is annoying on a single lane busy highway!

Taking off etc on level ground just take it easy, if you have the temperament . . . you will arrive just as quick but without excess strain, fuel use and wear and tear.

Towing more than about 700kgs is a whole different rhythm and slower and steadier than solo driving I find is much preferable.

Re:


Reminds me of my cousins husband. Forgot he was towing his boat (well over 3 tons), and decided to unleash the v8 twin turbo racing a guy at the lights.
Needless to say photos of a boat beached on the road ended up in the paperer the next day.

Torque loads are always highest in low gears. I like to get it going gently then keep accelerating harder and harder as you get through the gears. This limits the load through your drivetrain etc, but gets you up to speed fast enough that you aren't holding up traffic.

Re:


I have been towing the beast for several months now and in general it tows very well.
I had cause to go up a few steep hills recently and at first I just left it to the auto, but it started to hunt for gears as the hill had varying degrees of steep and flats, so I went back to manual, 3 and 4th gears goty me up the hill overtaking trucks that were not going as fast.

I have basically come up with the best drive practice (for me anyway)
Drive in auto 4wd and accelerate moderatly in most conditions.
When coming to a hill, break it back to manual (it automatically drops down 1 gear)
As I climb the hill, if it starts to loose revs, I kick it down another gear so that its revving freely and not labouring.
I keep a watch on the revs and keep them under 4k for longer than a few seconds.
As soon as I get up the hill I knock her back into auto and drive normally again.

My fuel consumption goes up towing (suprise, suprise) but not as much as some vehicles I have towe with in the past.

I have noticed a few things, perhaps somepne can enlighten me.
When I first start towing the first few klm, the car seems sluggish and less than fully responsive, but after a while it seems to get its second wind and performes much better.
When I first start driving after I have towed, the car seems to have more power and takes off like a scalded rat, but again, this settles back into normal driving after a while.

Is it me?
Am I imagining things and my right foot is out thinking my head?
Or is there something strange about the exy that I dont know about?

Cheers

Mine dosent hunt for gears when towing my 1.2t boat up hills, it just changes down and holds it.
As to your other observation yep your just imagining it.

CVT Transmissions don't "hunt" for gears because there are no gears.

The TCM (transmission computer) and ECM (Engine Computer ) modules and tens of sensors talk to each other and determine the best of an infinite number of available ratios (somewhere between lowest and highest) to have the engine at the optimum revs for required load and fuel economy etc.

The throttle is a "request for power" and the transmission is a slave to a "Mapping" algorithm with load, power request, speed, air pressure, air temperature etc etc etc as input parameters.

The engine valve timing, fuel injection is also part of the equation for power/economy and is also computer controlled.

It may actually be better, therefore, to most times just leave it in "Auto".

It "Knows" more than you!

As an aside, peak torque is at around 4,000rpm so that would be the best revs going up a steep hill whilst towing a heavy load.

Re:


Just came back from a small trip towing a 500kg trailer camper.
I didn't even know the damn thing was there, it just towed and didn't even faze the exy at all,.
I love the way the car tows with so much control over the tow, previous cars all swayed a little, the exy seems to control the sway and keep it in line.

Tomorrow I really test out the Exy.
I'm off for a couple of weeks and Ill be towing my 1200kg boat.
Add the camping gear in the fully packed back section and that will be around another 400kg (its like a tardis, it just swallowed everything).

I only have to drive about 400klm and plan to take it real easy, the load on the tow ball is about 80kg, so everything is nice and neat.

Ill write a report once I get back

Re: Very very pleased


Well it got there, more than can be said for the phone connection here
The 1200 kg boat, plus gear would have seen the old exy carrying about 16-1800 kg in total.
Set the cruse on 100 k by the speedo and drove from the central coast to Forster with virtually no effort
Only on two hills, around Bulledlah, it actually had to work hard to maintain the 100 k, and we were overtaking trucks crawling up the incline at the time.
Most of the time the revs stayed below 3500, regardless of the incline with the exception of the two hills mentioned.
Fuel consumption was ( by the indicator) 15-16 l per 100k.
After 3 days of driving around Forster and towing the boat for some fishing trips Im still running on the same tank I started with.
This vehicle is awsome

Ps,
My old ford falcon xt did the same trip with more effort and used 18-20 l per 100k
My Toyota Aurion was even worse 19 -23 l per 100 klm, although it seemed to labour less than the falcon and was smoother in gear changes
