Last time we reported about the next-generation Volkswagen Touareg R it was to relay rumors that the high-performance SUV might drop the automaker's venerable 5.0-liter diesel V10 TDI engine in favor of a V8 hybrid powertrain. Car and Driver is kicking the ball the other way with a report that the next version of the Toureg R will indeed still be a diesel, although carrying over the V10 probably isn't in the cards.

Instead, C/D reports that VW will be using its new 4.2-liter diesel V8 already available in the European Touareg. For Touareg R duty, the oil burner will likely be pumped up from its current 340-horsepower output to 380, along with delivering enough torque to move the SUV with irresponsible abandon. That's more power than the V10 TDI produced in the old Touareg R at 350, and probably enough for the new Touareg R to keep pace with other high-performance SUVs in the segment.

The bigger news is that C/D claims the next-gen Touareg R will actually be available for sale in the U.S in 2012 as a 2013 model. The new 4.2-liter diesel V8 will apparently meet current U.S. emissions standards, at least when installed under the hood of a Touareg R.

To date, the only R model ever offered by VW in the U.S. was the Golf-based R32. VW did intermittently sell a version of the last-generation Touareg in the U.S. with the same diesel V10 TDI as the R model in Europe (also called the R50), though tuned for less power and minus the performance goodies.
