Starting in 2013, a diesel-engine option on the Jeep Grand Cherokee will be available in the U.S., according to Chrysler’s chief Sergio Marchionne. Its spokespersons have said that aside from the Grand Cherokee, its “large” Chrysler family vehicles will also be offered with diesel power very soon. For the European market, the Grand Cherokee is offered with a 3.0-liter turbo-diesel V-6 built by Italian company VM Motori.
This engine will also be fitted on the Chrysler 300 (Lancia Thema). It’s believed to also be offered in the Chrysler 300 and in the Dodge Charger.
It’s probable that it will be used on the Dodge Durango, which is closely related to the Jeep. The smaller diesel six could also make its way into the light-duty Ram 1500. As currently applied, the 3.0-liter turbo-diesel delivers 224 hp and 406 lb-ft of torque. It will take a significant period of time before fuel-economy reports and performance figures become available since it will have to be thoroughly tested.
GM commissioned this engine back when it still held a stake in Alfa Romeo. VM developed it to be used in both transverse and longitudinal applications. Since that time, Fiat had taken back its full ownership of Alfa and also purchased a 50-percent stake in VM Motori.
As standard, the 2011 Jeep Grand Cherokee is powered by a new 3.6-liter Pentastar V-6 engine featuring double overhead camshafts (DOHC) and Variable-Valve Timing (VVT), as well as a high-pressure die-cast aluminum cylinder block in a 60-degree configuration. Able to provide up to 280 horsepower (209 kW) of output and 260 lb.-ft. (353 Nm) of torque at 4,800 rpm, the new Pentastar V-6 engine is up to 11-percent more fuel efficient than previous Grand Cherokee powered by a V-6 engine.
This powerful engine is mated to the W5A580 five-speed automatic gearbox that boasts of smooth shifts and allows for optimal fuel efficiency. It features an electronically modulated torque converter clutch and adaptive electronic control or Electronic Range Select (ERS) driver-interactive manual control. Since the fuel tanks of the new 2011 Jeep Grand Cherokee could contain up to 24.6 gallons of fuel, it could travel up to 500 miles before needing to refuel.
Meanwhile the all-new 2011 Jeep Grand Cherokee could also be powered by the 5.7-liter HEMI V-8 engine that comes with VVT for heighted level of performance and towing capability, as well as the Multi-displacement System (MDS) for better fuel efficiency.
Mated to a mated to the 545RFE multi-speed automatic transmission, this already iconic 5.7-liter HEMI V-8 engine could develop 360 horsepower (268 kW) of max output and 390 lb.-ft. (520 Nm) of max torque available at 4,250 rpm.
Interestingly, HEMI V8-powered 4x2 models of the Jeep Grand Cherokee could tow up to an unbelievable 7,400 lbs. Both petrol and diesel models of the new 2011 Jeep Grand Cherokee will be available in left- and right-hand drive in international markets.
