It should be a 2.4 petrol or a 2.5 diesel, but basically, 4x4 vehicle's engines are tuned for torque, not power. This makes them feel pretty sluggish, especially with a very heavy body to lug around. The 2.4 petrol produces 145bhp and 159lb-ft of torque. The 2.5 diesel in the same vehicle produces 141bhp, but the diesel engine is actually lighter & produces 252lb-ft of torque, making it feel a lot more lively.
