5.6 liter base 2wd.This engine has a wide torque curve,7 speed auto with a crew cab and 5.5 foot bed.averaging 19 mpg mostly highway. The ride is very tight,not as smooth in the rear as my Expedition yet very predictable.handling is predictable,steering feel is a little slower than I expect.It definitely doesn't feel twitchy at all.The transmission has a manual mode yet I haven't felt the need to use it yet.The brakes are 14 inch rotors in the front and stop this 5500lb vehicle impressively.i think we are going to be happy with the Nissan provided reliability is good.The vehicle has a 5 year 100,000 mile bumper to bumper warranty I hope is not needed.;
