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 engine is the same 4.0 L AMC 242 Straight-6 used in the Cherokee and Grand Cherokee. A 2.5 L AMC 150 Inline-4 motor was available on entry-level models until 2003 when the 2.4 L DOHC 4-cylinder engine previously used on the Chrysler PT Cruiser replaced it.
