Buyers of Infiniti's midsize M sedans have long appreciated its blend of luxury and performance. Following the introduction of an all-new design in 2011, the range-topping M56 continues to build on this popularity.
The M56's direct injection 5.6-liter V8 generates 420 horsepower and 417 pound-feet of torque. Estimated fuel economy is 16 mpg city and 25 mpg highway. Ride might be stiff for some -- but drivers are rewarded with exceptionally capable handling.
