Enjoy a full length video from Truck Trend. We'll call them Super SUVs -- SuperUVs for brevity: the 555-horsepower BMW X5 M, 500-horsepower Porsche Cayenne Turbo, and 465-horsepower Jeep Grand Cherokee SRT8. We wanted find out if these top-tier SUVs can comfortably travel at entertaining and demanding velocities with hefty loads and all seats filled, so we hooked up flatbed trailers and drove them to Willow Springs International Raceway. When you’re done you can browse our video library to watch all of our high quality videos covering a wide array of topics.
