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.
Although Jeep hasn't announced power ratings for the Pentastar, it's certainly an improvement over last year's 202-horsepower 3.8-liter V6, which was previously used in Chrysler and Dodge minivans. The Pentastar engine produces 290 horsepower in Jeep's midsize Grand Cherokee, where it debuted for the 2011 model year. The new engine is sure to provide yet another boost to Wrangler sales, which already benefitted from several new features and an interior update for 2011.
