Coughing up blood is the spitting up of blood or bloody mucus from the lungs and throat (respiratory tract).
There aren't many V-6 options in the class, and the Cherokee surpasses the Chevy with a more fun-to-drive experience; it's neck and neck with the Escape's sprightly, turbocharged 2.0-liter four-cylinder. All-wheel-drive versions of the V-6 Cherokee are rated at 19 mpg city, 27 mpg highway and 22 mpg combined.
The Grand Cherokee boasts four engine choices. Standard is a smooth 290-hp 3.6-liter V6, which returns up to 17 mpg city/24 mpg hwy. Optional for drivers interested in better fuel economy is a 240-hp 3.0-liter turbodiesel V6, capable of up to 21 mpg city/28 mpg hwy.
