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.
On the Jeep, it is mated with an all-new, electronically-controlled transmission with five forward ratios. An alternate second gear ratio will provide improved performance. A 3.7 liter version of the 4.7 is used on the 2002 and up Jeep Liberty (known as the Cherokee outside North America).
