Volkswagen has been spotted testing prototypes for an updated version of its Touareg mid-size SUV.

The Touareg disappeared from U.S. shores after 2017, prior to the current third-generation model being launched. The SUV is now set to receive an update that will be revealed in the summer, and no, the nameplate isn't returning to these shores.

The SUV will have new styling front and rear, including the addition of a light strip at the front and more advanced matrix LED headlights boasting a brighter and more precisely controlled light beam. The VW logo at the rear will also be illuminated. These elements are partially camouflaged but we can see the intakes in the front fascia resemble those on the Tiguan. The compact Tiguan is also about to be updated.

It isn't clear what VW has planned for the powertrains in the Touareg. It's likely some of the current diesel offerings will be dropped and possibly replaced with plug-in hybrid options. The top-of-the-line Touareg R, which is also a plug-in hybrid, may also get increased performance. Its current turbocharged 3.0-liter V-6 and electric motor combination is good for 455 hp and 516 lb-ft of torque.

For the interior, VW has confirmed softer materials for areas such as the armrests and center console panels, in addition to technology updates that will include wireless connectivity for Apple CarPlay and Android Auto and an improved navigation system featuring lane-precise guidance and high-resolution HD maps.

With VW offering the mid-size Atlas here in the U.S., and planning a mid-size electric SUV that will likely go by the name ID.8, this could very well be the last Touareg equipped with an internal-combustion engine.

Note, the Touareg is a twin under the skin with the Audi Q7 and Porsche Cayenne, and both these models are also being updated. Prototypes for the updated Cayenne and updated Q7 have also been spotted.
