The RTL-e trim on the Honda Ridgeline refers to the top of the line model that comes standard with a host of features and upgrades. Some of these include a 10-speaker premium audio system, LED headlights and taillights, front and rear parking sensors, power sliding rear window, and more. The RTL-e is also the only trim that offers Honda's unique i-VTM4 all-wheel drive system. This system constantly monitors traction conditions and can send up to 70% of torque to the rear wheels when needed.
