Main points:

"The V6 offering comes after disappointing sales of the V8 edition of the German off-roader in Europe, where buyers have shied away from the more powerful but notoriously thirsty Cayenne S and Turbo in favor of more fuel-efficient luxury offerings such as the Volkswagen Touareg.

In the United States, the Cayenne went on sale in March and hasn’t experienced any such sales disappointment. The truck is selling at the rate of about 1500 units per month, at which rate it will breeze past the company’s U.S. sales target of 12,500 annually. The U.S. number represents half of the total worldwide production prior to expanded capacity for the newly announced model.

Sources suggest that the 308-hp, 553-lb-ft 5.0-liter V10 turbocharged diesel V10—currently offered in the Touareg—could be next for the Cayenne."
