our speed limits are 100 km/h, I drive 120-130.... at 150 they confiscate your car and fine you $10 000.00 Mileage is now 8.9 per 100km/h.... and I am sure that A6 could not tow 7200 lbs, and drive through snowbanks!.
For an SUV I highly doubt any come even close to it in mileage. I am really beginning to love it. ... still wish it had a 7th gear.2023 TUFF 25

I read when it came out it was an older diesel from Spain or someplace, and not as advanced as others. That was when new in the Liberty.

I remember reading something not as refined, back then, as other diesels but who knows. Maybe it was the noise? I found this:
"For now, the Jeep Liberty CRD is the first mid-size SUV to offer diesel power in the U.S. Its 2.8-liter, 4-cylinder Common Rail Diesel (CRD) is the same unit that powers about 70 percent of Jeep Liberty models in Europe. Sourced from VM Motori, an Italian company partially owned by DaimlerChrysler’s Detroit Diesel, this engine features an efficient direct injection system that supplies fuel at pressures up to 24,000 psi. Such high pressure produces finer atomization, leaner combustion, and higher power...key to a more modern diesel engine. An electronically controlled, variable geometry turbocharger also features moveable turbine vanes, acting like a small turbo at launch and a large turbo at higher speeds. During testing, this sophisticated system worked seamlessly while driving the hills above Santa Barbara, California, achieving its aim of delivering responsive low- and high-end torque.
At start-up, there’s no mistaking this Liberty’s powerplant for anything but a diesel. The distinctive engine clatter is present while idling around town, but at highway speeds – which are achieved with remarkable ease – engine noise is all but indiscernible. Other common diesel quirks of the past, such as smoke and odor, are completely absent. Glow-plug warm-up time is down to less than two seconds on a cold start. "

Also: "The Liberty CRD is equipped with a five-speed automatic transmission and 4WD, a package that allows an estimated city/highway fuel economy rating of 22/27 mpg and a driving range approaching 500 miles. This is quite impressive for a 4,306 pound SUV, especially when contrasted with the 17/22 mpg fuel economy rating of the gasoline V-6 automatic Liberty variant.""As government expands, liberty contracts." -Ronald Reagan

Here it is, the new one is different in the Grand Cherokee:
(road test)
"Date: July 2006
Miles: 18,000
Sales of the Jeep Liberty CRD turbo-diesel have exceeded expectations and that's great news. It's about time Americans got more familiar with the efficient diesel engines that are common in sport-utility vehicles sold in Europe.
The bad news is that production for the Jeep Liberty diesel has stopped. The current 2.8-liter doesn't meet new emission rules. So, you either have to settle for one on a dealer's lot, or wait for a diesel Jeep Grand Cherokee due next year.
The Liberty was a test of the acceptance of diesel SUVs in America. We certainly accepted our 2005 Liberty which has been fault free a full year and 18,000 miles. Our overall test results of 21.9 miles per gallon may be only 10% better than a V6 gas Liberty, but it exceeded 28 miles per gallon on the highway."
"What didn't meet our expectations, unfortunately, was actual miles per gallon. After 14 months, and over 20,000 miles, our total test mileage settled at 21.7. That's at the bottom of its 21 City/27 Highway government fuel economy ratings. Still, the last V6 Liberty we tested only managed in the high teens... ...it gave Jeep planners confidence enough to introduce a Grand Cherokee with an ultra-clean Mercedes V6 turbo diesel next year."

Grand Cherokee 2008--
"The 3.0 liter Mercedes-Benz common rail diesel (CRD) is well-suited to the Grand Cherokee, producing 215 horsepower and a very healthy 376 foot pounds of torque. The torque figures put the diesel on a par with the 4.7 liter V-8 (305 HP and 334 foot pounds of torque) and 5.7 liter HEMI V-8 (330 HP and 375 foot pounds of torque). It’s an even match up when it come to grunt, but when it comes to fuel efficiency, the 3.0 liter CRD shines.
ᅠ
2008 Jeep Grand Cherokee 4WD EPA Mileage Estimates:
Engine City Hwy
4.7 liter V8 14 19
5.7 liter V8 HEMI 13 18
3.7 liter V6 15 19
3.0 liter V6 CRD 17 22
.
Over the test period, our Grand Cherokee’s turbo-diesel delivered endless torque as it turned in a very respectable 21.6 miles per gallon (MPG) combined, with 24.3 MPG on the highway. Those are excellent numbers for a 5000 pound Trail-Rated SUV with full-time four-wheel drive. When it comes to 4WD capabilities, this isn’t a poseur … it’s the real thing."

That is about what I get for mileage, my 2006 witht the 4.7 got 16-7 mpg.
This is a lot quieter, and has a lot more power.2023 TUFF 25

Loads of torque, I read when they introduced the Liberty it had enough motor to tow more than they felt the vehicle could handle. I wish I had a smaller turbo diesel vehicle, some day. I fail to understand what they are doing with the price of diesel though, it was 4.26 here yesterday at one place. No excuse for that.
