2005 JEEP LIBERTY LIMITED CRD
ON SALE: Now
AS-TESTED PRICE: $31,405
POWERTRAIN: 2.8-liter, 160-hp, 295-lb-ft turbodiesel I4; 4wd, five-speed automatic
CURB WEIGHT: 4296 lbs
0 TO 60 MPH: 10 seconds (est.)
FUEL ECONOMY: 23.0 mpg (EPA combined), 23.2 mpg (AW observed)

The American model is stronger than the Euro version we drove a little over a year ago. That one got to 62 mph in 13 seconds; the U.S. model gains about three seconds. Plus, our version is more responsive in the crucial 60-to-80-mph zone on the freeway. It’s all about enhanced torque and gearing in the five-speed automatic.

EPA ratings are 17/21 city/highway for the 3.7 and 21/26  for the CRD. We saw 17.7 mpg in the V6 AutoFile test and 23.2 in the CRD, an improvement better than 30 percent.


If saving money and fuel were our only concerns, we’d consider Liberty’s base 2.4-liter 150-hp gasoline four-cylinder, EPA-rated at 21/24 mpg and with a range of more than 400 miles. It gives up only 10 hp to the diesel, though torque is a meager 165 lb-ft. But the base truck is 300 pounds lighter and comes with a six-speed manual gearbox, offsetting the performance loss. You can’t get upscale Limited trim, and towing capacity is 2000 pounds vs. 5000 for the CRD.

21/26 for the diesel? That's not very impressive!

[mrthompson]

The Liberty is a heavy beast.  

[stodge]

So is my dad's Volvo XC90 diesel, and it gets much better figures than that!

Well one good sight to compare is http://www.fueleconomy.gov/feg/bymake/jeep2005.shtml
Looking at the cherokee/liberty in UK dealer web sight. (mpg based on UK gallons) The 2.8Lcrd manual gets 23.5mpg city/ 30.4mpg av/ 36.7mpg highway.
Auto gets 22.2mpg city/28.5mpg av/ 34.4mpg hy.

The cherokee manual 2.5Lcrd 141hp 251lbft got 24.1mpg city/ 31.4mpg av/ 37.7mpg hy (UK gallons)

I think for a motor that's getting 295lb-ft with an automatic. 21/26 mpg (US gallon) isn't too bad.  
If the US had the manual transmission. Maybe 1 or 2 MPG more on the highway.  
If they offered the smaller 2.5Lcrd. You could add another 2-3 mpg gain.

I think most people think of diesels getting 36-42mpg. But they need to remember those numbers are from vehicals with diesels under 2.0L or those are UK gallons not US gallons.

21/26 mpg(imp) works out to 8/11.2 L/100km.  The reason it's not very impressive, is my X-Trail gets better mileage than that, as does CR-V and Forester.  All are gasoline-powered.

So what you have is a cute-ute, with the drawbacks of a diesel (fuel availability, mess and up-front cost), without the primary benefit (fuel economy).  The main things it has going for it are torque and off-road capability.

[tortoise]

I imagine you'd be hard pressed to find another vehicle that could tow 5000 lbs and still get reasonable fuel economy.   If you are doing a lot of towing this vehicle could make some sense.

[ktm525]

Cphansen your mpg in brackets should be US rather than IMP. Otherwise your calculations are fine. Does your X-trail really get better than 8L/100km city? Impressive. As Tortoise already pointed out; the Liberty can tow more.

Transport Canada reports X-trail consumption (AWD auto) at 8L/100 km hwy/ 10.8L/100 city. Bang on with the Liberty CRD.

Nope, those figures are in reverse order - 8L/100km highway, 11.2L/100km city - I'm sure.

[ktm525]

oops. Now I screwed up. I meant 8L/HWY.

[Craig]

Correct, which makes fuel economy a shade better than the CRD Liberty.  We get about 9.5 L/100km in real world driving now that it's broken in.

For towing and off-road use, I can see the benefits of the Liberty CRD.

[stodge]

I'm talking about economy with nothing being towed - the CRD doesn't look attractive at all this way.

[ktm525]

THE CRD in the Liberty is already a older design. The Liberty is HEAVY @ 4296 lbs. For this weight I think the mileage is very good. My Dakota Quadcab 4*4 (full time AWD) is similar in weight and I get 18L/100km city and 15L/100km hwy.

[mrthompson]

Give us a mini-Cummins diesel (2.5 to 3.0L)and put it in the Liberty, Dakota, etc.  That would be a wicked setup.  

[safristi]

Mini Cum'ins.....try more Vitamin E and Omega 3 in yer DIET...plus a two_four of 3 Elephants beer......

[sly]

I think that the CRD has excellent fuel economy for the type of vehicle it is.  

Liberty and X-Trail are two different beasts. The X is a soft duty SUV, what most people need.

The Liberty is a heavy duty machine, which is for real off road or tto tow.

Many people get the Liberty without ever using its capabilities, so yes it becomes a waste of money and fuel.

Lets be honest, the CRD numbers are great in that they are as good as many midsize sedan.

[66coronet]

Well if you want to use a jeep for light offroad and fuel mileage. Then you may want to wait for the jeep compass or scout. That's sharing the dodge caliber's platform. It's been said that, that platform will use the new world motors, 1.8L, 2.0L, 2.4L, and VW's 2.0L TD.
