Gave the Patriot 2.4L CVT a decent highway run yesterday. I was majorly disappointed.

In city driving alone or sometimes 1 other passenger I normally get about 10.3 - 11.4L/100kms (28-24MPG) Which I am reasonably happy with for a car of it's size.

Yesterday I loaded up the Patriot with Myself and 4 other passengers and went on a big drive. Before I say anything else, all my passangers were average weight for people in thier late teens, so car full of heavy people was not the problem.
The performance in the city was noticeably soo much worse. I pulled onto a main road up a hill and had to accelerate to over 4000RPM to get up to speed without someone running up the back of me. Felt like a lifetime to get to 4000rpm as well.

Finally got to the highway and had the cruise control set on about 110Km/h (70mph). Every time I came to a hill the car would drop to 90km/h (55mph) before it started to pick up speed by itself. In all other cars I have drove they would pick up speed straight away and only drop about 5kmh maybe 10 at the worst at the foot of a hill.
But dropping 20 in the patriot is just ridiculous. I think the CVT was pathetic as it took a long time to build up any RPM to keep it up the hill at a decent speed.
At the foot of each hill I had to disable Cruise control and plant my foot to the floor, when it revved up to over 4000rpm I would let the accelerator out slightly and the RPM would stay at about 4000 and the car would cruise up the hill at about 105-110km/h.
There was about 4 or 5 hills that I had to get up on the trip.

When I got to the end of the freeway, my average fuel consumption was about 10.3L per 100kms (28.5MPG)
On the flat I was cruising 100-110km/h. I was majorly disappointed with that consumption since it was exactly the same as my city consumption.

Are all Patriots this slow and thirsty on the Freeway?

Once I was off the Freeway I was in the busiest city in Australia during the afternoon peak hour. The Patriot was constantly changing between revving hard and then quickly dropping before having to rev really hard again. I was just going with the flow of traffic, I wasn't driving like a maniac.

So does everyone elses Patriot struggle with weight? Or is it just the CVT ones.

The back passengers were not too impressed with the rear leg room either. And they were less then 6 foot tall.

I got a 2500Km drive in February next year and Ill have all the Holiday luggage packed in the car. I really don't want to do it in the Patriot anymore. It struggled yesterday and it only had 5 people in it and NO luggage at all!

This car looks cool around town and is good on dirt tracks with my mountain bike in the back. But it's really gutless on at any speed above 70km/h

Does anyone else feel like me? Or am I just too used to 6 and 8 cylinder cars???

My Old 3.5L V6 sedan (with a kerb weight similar to the Patriots) loaded with luggage and 1 passenger got no worse then 7L/100kms (40mpg) on the highway.
 
i know this is no consolation, but cvt transmissions are totally crap (IMO)

our manual CRD is a dream - heaps of torque so very little gear changing needed

i'm not having a go or saying 'ours is better than yours' but CVT's are crap (did i say that already?)
 
I'm with Harold on this one. the CRD 6 speed was available in Oz, you should have got one. The petrol /cvt was great in my Caliber ( only 2 litres ) , but its a totally unsuitable combo in a Jeep. If you have petrol at least get 5 speed manual , you have got some control over the trans.
The FD2 available in USA would be a complete transformation with a CRD & 6 speed box.But the Greenies who are in charge of America Wont let them have Diesels.

Your poor economy may be down to driving style ( I hate cruise control ) or that the Pat. just isnt up to long distance hauling with a load.

Dont know how many miles on yours , but it really should free-up between 5--10,000 miles!!

I think the problem was a 2.4L Petrol with a CVT trying to move about 1800kgs at reasonably quick speed it had to work the engine a lot harder then you normally would.

What's worse, today someone was saying how he got about 9L/100kms out of his large sedan while it was loaded up to almost 2000kgs. Powered by a 5L V8.

9L out of a 1.9t V8 on the highway! while my 1.8t 4 cylinder was getting 10L!
 
Personally, I'd keep my fingers away from the cruise control. What's it actually for, except making sure your right foot is in the wrong place when you might really, really need it.
It's yet another invention, like the heated coffee-cup holder, that's kept the wolf of redundancy away from the design team's door.

Yea !! I like to have complete CONTROL over my driving . Why would you have cruise on a car with a manual gearbox??? Clever guy in the engineering dept. the day that silly idea came out!!
 
28.5 mpg around town is really good. I have the CVT and 2.4L (4x4) also and usually see 22-23 mpg around town and 27-28 mpg on the highway. My last long trip was also with 4 adults and their luggage for a weekend stay up in the mountains. However, I cruise at 60-65 mph. The Patriot does not have great aerodynamics and once you go above 65 mph, fuel mileage suffers. Try slowing down a bit on the next trip and see what you get. As for the high rpms and huge mph drop, maybe ask the dealer if it needs a flash update or something? I don't ever have a problem setting the cruise and having it stay within a mph or two of the originally set speed. And it never bounces all the way up to 4000 rpm while cruising, even going up some normal mountain highway roads (although on some steep grades it has done this).
 
My question: Do they use Imperial Gallons in Australia ? because your mileage seems quite good for a U.S. gallon. I have no trouble going up hills or passing with the 5 speed manual but it still does not have the performance of our thirsty 6 cyl Cherokee Sport which gets about 20 mpg.

We don't use Gallons here at all. I just used an Online converter to help people overseas. I think it was an Imperial Gallons... not that I know what that is.

When I said it dropped 20km/h on cruise control, this was just as I started going up a hill. On the flat it could hold the speed.

Most cars lose speed when starting to go up a hill on cruise control, but I have never seen any other car I have been in lose more the 10km/h. I like kickdown in a proper automatics because the RPM increases instantly, CVT has to wind itself up which takes longer.

Maybe 60-65mph may improve economy but I don't want to do any less then 70mph (110kmh) because that is just my driving style.

The diesel was probably a better option, but they stopped making it here for a while, and that is when I bought mine :doh:

The redline limit is 6250RPM. So why would 4000RPM be some sort of a problem? Besides, it's a small engine - you do need to rev those up a bit to get real power out of them.

My engine is quite responsive - I step on the skinny pedal, it revs up. My Jeep is no race car but it keeps up with traffic rather well, even when full of gear.

Finally got to the highway and had the cruise control set on about 110Km/h (70mph). Every time I came to a hill the car would drop to 90km/h (55mph) before it started to pick up speed by itself.
Okay, this sounds very weird. My cruise control has always kept the speed fairly steady - within plus or minus a few kilometers per hour.

When I got to the end of the freeway, my average fuel consumption was about 10.3L per 100kms (28.5MPG)
This sounds about right. I have about the same fuel consumption during prolonged cruising around that speed.

My Old 3.5L V6 sedan (with a kerb weight similar to the Patriots) loaded with luggage and 1 passenger got no worse then 7L/100kms (40mpg) on the highway.
That's physics for you. :) A more aerodynamic shape and an engine that can keep the RPM near idle helps fuel economy in that situation.

I really don't understand those who complain about cruise control. It makes long distance driving so much more pleasant - and helps avoid speeding tickets during these times of overly fanatical speed control. Full control? Tap the brake and it's off. I don't really see a problem here.
 
The only issue I see with folks who use the cruise a lot, is they sometimes forget to NOT use it when the weather is bad. Snow, ice, or even rain on the roads is a time to NOT use cruise. I have to remind my wife about that often as she has the cruise on a lot.
