The four-door, five-passenger Ridgeline is available in three trim levels: RT, RTS and RTL. All are powered by a 250-hp 3.5-liter V6 engine, mated to a five-speed automatic transmission; Honda's Variable Torque Management four-wheel drive system (VTM-4) and a limited-slip lockable rear differential are also standard. A trailer hitch is standard on all trim levels, rated for a maximum towing capacity of 5000 pounds, and the RTL can be outfitted with an available voice-activated navigation system, including a rearview camera and Bluetooth HandsFreeLink wireless connectivity. Standard safety features include anti-lock disc brakes with brake assist, Vehicle Stability Assist with traction control, front side-impact airbags, front and rear side curtain airbags, active anti-whiplash front head restraints and a tire pressure monitor. The Honda Ridgeline carries over unchanged for 2010.
