Winner: Jeep Grand Cherokee SRT8
Runner-Up: Porsche Cayenne Turbo

There are other vehicles in this category that are faster -- but not many. When we tested the new SRT8, which is powered by a 470-hp, 6.4-liter V-8, it scooted to 60 mph in 4.6 seconds. And yes, the Porsche Cayenne Turbo is faster to 60, but it costs almost twice as much. Granted, the factory power runner segment is a little silly, but for good fun at a value price, you can't do better than the SRT8. Now, if you do have that extra $47,000 lying around, the Cayenne is a good choice, too. Excellent power delivery, phenomenal handling, and no shortage of horsepower or torque. And it can tow.
