The 2010 Mazda CX-9 is a large seven-passenger crossover SUV that's available in three trim levels: Sport, Touring and Grand Touring. Stepping up to the Touring version adds heated mirrors, leather upholstery (for front- and second-row seats) and heated power front seats. Fuel economy is slightly below average, though, at an EPA-estimated 16 mpg city/22 mpg highway and 18 mpg in combined driving
