To activate, Jeep's instructions say the SUV must be stopped on a level surface before fully depressing the brake pedal - while in Drive - and then pressing the Launch button. While holding the brake, mash the accelerator pedal to the floor within a half-second and the engine will rev to a predetermined rpm. Once the engine speed is up, all the driver has to do is lift the brake and the SRT8 launches perfectly every time.
"Jeep rates the SRT Grand Cherokee at 4.8 seconds from zero to 60 mph, but I discovered that this is a conservative figure: Using the SRT's onboard software and a special launch button, I was able to consistently rip off 4.5-second zero-to-60 times, and SRT engineers say that they've been able to achieve 60 mph in 4.2 seconds under perfect conditions."

MSRP is $60,295.
First off, 0 to 60 in 4.5 secs is very fast.
Secondly, it's a bit pricey for an American-made SUV. It has a lot of power on tap, but if you are towing something big like a boat, I would figure you are going to get a full-size pick-up truck/SUV with bigger towing capability.
Thirdly, it's out of my price range. I think it's marketed at speed/power lovers who don't want an SUV for utilitarian purposes and don't care about saving gasoline/the environment.
