With the growing demand for the Porsche Cayenne, the German automaker is reportedly stepping up production. The first generation Cayenne made its debut back in 2002 and demand has continued to grow ever since. It's powered by a 3.6L V6 engine producing 300hp. The Cayenne S features the same 4.8L V8 from the Panamera S and produces 400hp. The Turbo comes with the Panamera Turbo's 4.8L twin-turbo V8 that produces 500hp.

The long-anticipated Cayenne S Hybrid will use an Audi-sourced 3.0L V6 engine producing 333hp along with a lithium ion battery capable of 47hp for a total of 380hp, just 20hp shy of the standard Cayenne S. The Panamera may be receiving the same treatment as its Cayenne sibling as sales of the four-door coupe could top 28,000 units by the end of this year. For comparison, approximately 20,000 units were sold by the end of the car's first full model year. The 2011 Cayenne made its debut back in March at the Geneva Motor Show. Sales of the luxury SUV are up 37 percent in the first half of 2011.
