The Jeep Grand Cherokee Trackhawk makes a massive 707 hp. That makes it the most powerful stock SUV around. But this Hennessey Cadillac Escalade is far from stock. It might outweigh the Jeep by a few hundred pounds, but that doesn't matter when it has an extra 98 hp. Does it? After all, that's 805 horses along with 812 lb-ft of torque.

So when they match up on the drag strip, it's a tough matchup. The real winner might be whichever company is managing to build these absurdly tough all-wheel drive center diffs.

No, that's not right. The real winner is the driver that finishes first. Watch and see who ends up at the line first.
