The world wasn’t ready for the Porsche Cayenne Turbo GT. When the numbers came out, everyone wondered if they were actually possible. So it has 631 horsepower and 626 lb-ft of torque. We’ve seen those numbers a bunch of times out of big SUVs and trucks. That isn’t the impressive part. The silly part is that this 4979-pound SUV does 0-60 mph in 2.8 seconds and can lay a quarter mile run of 11.1 seconds. Not only straight line speed, but it also recorded a 7:38.9 Nordschleife lap time. That is faster than the 997 Porsche 911 GT3. What is going on here?
