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.
Only one engine was offered in the 2015 Nissan Xterra: a 261-horsepower 4.0-liter V6. The Jeep Wrangler produces 281 horsepower from its smaller 3.5-liter V6, and the optional 3.2-liter V6 in the Jeep Cherokee has 271 horsepower.
