It's no RR Sport. Not as fun- but 27.4mpg hwy and between 20-22 overall. The gas mileage is great and less carbon emissions. Diesel engine noise is annoying. Porsche will win if they can combine sport and "green" in the new Cayenne!
Gas mileage, better for environment. Satellite radio, great i pod synch. Watching the mpg read out in the car--it's like a game that you can play with depending on how you drive,
Quality of material is a little cheap (compared to RR). Diesel is what it is, but the gas mileage is awesome. Not too sporty a drive..more suburban car/soccer parent drive. Not very rock n roll!
