100km I get about 2000 rpm

110km I get about 2050 rpm

I dont see the RPM needle really move but once I past 110km I see the needle hitting 2500rpm.

2007 FWD CVT AUTO

 

Its not FD1 or FD2. Its just plain CVT!

 

At around 75mph, my 2008 with 5spd was running about 3400 rpms. My 2011 with CVT runs about 2500 rpms at 75mph. Both of these are(were) FWD. My 2011 definitely runs at lower rpm than the 5spd did. 6th gear would be great for these little high revving engines.

 

My 2010 4x2 / 2.4L / 5 spd hits about 2300 rpm's @ 100km/h(60mph) on the hwy.

 

Here is what Consumer Reports reported:

2007 FDII CVT: 2,505 RPM at 60 mph
2009 FDI CVT: 2,155 RPM at 60 mph

Its not FD1 or FD2. Its just plain CVT!

Doesn't the FDII have a lower geared top end? That would explain CR's findings. That is also one of the reasons I started this thread. I want to see if and how much of a difference there is between FDI CVT and FDII

 

FD1 5 speed, 2008 sport model, 2800rpm at 75mph

 

Here's a cut/paste from another thread. This was done with my FDII on almost flat road using cruise control.

45mph - 1850rpm
50mph - 2050rpm
55mph - 2250rpm
60mph - 2500rpm
65mph - 2650rpm
70mph - 2900rpm

Thanks UA! It looks like the RPM's at 70 are significantly higher for FDII than FDI, and now I know by how much

 

My 09 5-speed FD I looks like 2200 or so @60mph in 5th and 3300 or so in 4th@60mph. 65mph is about 2350 in 5th.

 

Today I observed 65 MPH as 2000 revs in my 2011 FD1 4X4. Very quiet.
All the reviews I've read complaining about engine noise seems overstated, but I think most reviews were based on the 2010. They have probably improved on this for 2011.

Otherwise, the 9-speaker Boston Accoustic could cover up the roof being opened with an air chisel.

 

I thought that I read somewhere on this forum that the final drive ratio on the 5 speed manual was changed sometime after mid 2008. Our's is an early 2008 built in November 2007 and I am satisfied with the highway performance as it is and would not want a drive ratio with lower RPMs and less performance. It seems to me that bigger tires would of course have lower RPMs. On the highway at about 110 kph in 5th gear our tach shows 2600 and in 4th gear at 110 kph it shows 3400 RPM. Incidentally one time I made a long highway trip and never used 5th gear only 4th gear and we still got about 26 mpg even with the higher RPMs.

 

Yes, because of the lower gearing for FDII equipped patriots the rpm on the highway are way higher. keeping it at 100kmh is a good speed for long distance travelling in my rig. good milage then and no buzzing 4 cyl!

 

swap out the computer chip to change the engine parameters. but what's the point? every engine, despite that, has it's limitations & more rpm's simply means burning more fuel and more strain on the engine unless you rebuild it with higher grade parts to take the added stress.

 

I wonder if the 2011 FDII has lower RPMS at the top than previous years

 

Nope.

thats part of the "charm" of the FDII, its lower gearing for off roading.

 

The axle ratio on the FDII is 35% shorter (numerically higher) than the FDI CVT which uses the same CVT gearing. Thus, the engine speed will be 35% higher for any given vehicle speed with the FDII than the FDI CVT.

There is a slight difference in tire sizes available which will vary non-FDII Patriots engine speed by about 3%.

Also, the Patriot launched in 2007 with two different 5th gear ratios between 2WD and FDI manual transmissions. The FDI was 0.81 vs. 2WD 0.72. Sometime during model year 2008, the FDI got the same 5th gear ratio as the 2WD.

My 2007 Compass FDI 5-speed turns about 3000rpm in 5th gear at 70mph, 3400rpm at 80mph. I must say the engine is not what I hear at 70 or 80mph.

 

for my diesel
50mph - 1750rpm
60mph - 2100rpm
70mph - 2400rpm

 

the 2011 comes with upgraded insulation so they should be at least a little quieter. my fd1 2011 is pretty quiet to me but my last vehicle was a 2000 dakota v8.

 

My figures agree with UA's for the 08 FDII.

Now we just need someone with an 11 FDII to see how they compare to those too.

 

Like on the first page, the RPM's for a 2011 FDII has not changed :

45mph - 1850rpm
50mph - 2050rpm
55mph - 2250rpm
60mph - 2500rpm
65mph - 2650rpm
70mph - 2900rpm

 

Thanks guys. The intent of this thread was to know what to expect noise wise (and mpg wise) on newer models compared to older ones, and how different FD2 (CVT2L) is from the CVT2 (FWD CVT and FD1). Thanks for the confirmations, and answering what I was wondering. Hopefully others find this information useful as well.

 

4Χ4 2.4 litr
manual transmision with 5th gear I get at 3000 rpm 118km(73 miles)/hour

the 2.4 Cvt at 3000 rpm get 140km(87miles)/hour

 

2.4 Avenger with 4 speed Auto slush box---60 mph = 2000 rpm in 4th.

 

I have 2012 jeep patriot 2.4l 4x4:
at 80 km the rpm 2500
at 100 km the rpm 3000
at 120 km the rpm 3500
is this normal ??? knowing that no noise at the engine.
