2009 jeep grand Cherokee Laredo trail rated

He is correct in describing how the four wheel drive works, adjusts automatically when it senses wheel spin. And the gas mileage rating will be 15-20 mpg depending how and where you drive. You can look up the EPA gas mileage ratings. If you are concerned about mileage, consider a smaller SUV like the Jeep Cherokee, Honda CRV or Toyota Rav4. Since most of the vehicles on the road are mostly large and huge, I want to be in my Jeep Grand Cherokee if somebody crashes into me a on a slippery road. There will be a better chance I'm still alive to get another full size Jeep.
