It looks just like the petrol-fueled Sorento but offers a boost in torque.

The diesel-fueled Kia Sorento is on the way, and these photos catch the SUV while outside testing and being checked by officials from America's Environmental Protection Agency.

Aesthetically, there's nothing that sets the diesel model apart, except that this one has a pair of exhaust outlets coming out the back, instead of the single, large oval tip on the petrol-fueled V6 model. The example in these photos appears to be in a basic trim that lacks the LED headlights, foglights, and taillights from higher level models. Plus, this one has an actual fuel door in place, unlike a previous test mule. While not visible here, there's no reason to expect any major alterations to the cabin. 

Sorento reviews:

Kia isn't yet officially confirming details about the diesel powertrain, but all signs point to the Sorento sharing its 2.2-liter turbodiesel powertrain with the Hyundai Santa Fe where the powerplant produces 190bhp and 322lb-ft of torque. In the Hyundai, it only comes with an eight-speed automatic and a choice of front- or all-wheel drive. 

Rumours suggest the updated diesel Sorento would go on sale in late 2018 or early 2019.
