"For enhanced responsiveness Cherokee also offers a 2.5 L turbo diesel with intercooler and electronically controlled fuel injection. It produces 115 HP and 300 Nm of torque." Got that from an Argentina Jeep site. BTW, 300 Nm = 221.2686 lb-ft.
This is from a South American site, regarding the Jeep Liberty: "The turbo-diesel is also new for Jeep, and marks the first time a Mercedes engine has been fitted into a Chrysler vehicle, the unit a thoroughly modern double overhead camshaft common rail four-cylinder that produces 105 kW at 4 000 r/min and a whacking 343 Nm of torque at 2 000 r/min. This makes it far and away the most powerful 2.5-litre turbo-diesel engine available in a 4x4 in SA.
Top speed is 164 km/h, and it accelerates from 0-100 km/h in 15.3 seconds.
The 2.5-litre engine provides a fuel economy of 7.5 litres/100 km on the extra urban cycle, 11.7 litres/100 km during city driving, and 9.0 litres/100 km on the combined cycle."
105 kW = 140.8073 hp
343 Nm = 252.9838 lb-ft
7.5L/100km = 37.6641 mpg (Imp)
11.7L/100km = 24.1437 mpg (Imp)
9.0L/100km = 31.3868 mpg (Imp)
With fuel economy and torque figures like that, I can live with 30 less hp.
Unfortunately, I don't know if that motor uses the same bellhousing pattern as the stock transmissions. AFAIK, that is a Mercedes Diesel engine which should be quite reliable. Remember that they are a well-known commercial-duty truck manufacturer and the Diesels in their cars have a reputation for durability.
And of course, you'll have to figure out some way to get one of those motors into North America since they are not currently being sold domestically.
