Matthew DeBord/BIHere's the verdict on the Mazda CX-9 crossover, the automaker's largest car with room for seven passengers in its three rows: It's terrific! Now the bad, and there's only one small complaint: the Skyactiv-G 2.5-liter, four-cylinder turbocharged engine cranks out only 250 horsepower, less than what you'd get in a competing vehicle with a V6 (think GMC Acadia, Ford Explorer, Honda Pilot).
