The Ridgeline comes in three trim levels--RT, a new-for-2012-Sport, RTS and RTL--and they are all powered by a 3.5L, 250-hp V6 engine that makes 247 lb-ft of torque and utilizes a drive-by-wire electric throttle. The engine is mated to a 5-speed automatic transmission in all three models, and they all feature a locking rear differential. The Ridgeline features a towing capacity of 5,000 pounds and a 1,500-pound payload capacity. The Ridgeline is known as much for its smooth ride as for its tough capabilities, thanks to its closed-box frame and independent suspension. It also has a slew of standard safety features, such as 3-point seatbelts for all five seats, air bags all around, anti-lock brakes, stability assist with traction control, brake assist and tire pressure monitoring. All of those features are standard across the board. The base-level RT has air conditioning with an air filtration system, power everything, cruise control and a 6-speaker audio system with MP3 playback. The Sport adds 18-inch wheels, fog lamps, an upgraded stereo and a leather-wrapped steering wheel. The RTS adds a security system, privacy glass, dual-zone climate controls and a more powerful 7-speaker stereo system with controls on the steering wheel. Like the RTL, it comes with a trailer harness. The RTL has everything the RTS has, plus a moonroof, heated mirrors, fog lights, a leather-wrapped steering wheel, heated front seats, HomeLink and XM satellite radio. It's also the only trim level to offer an optional navigation system, which also adds Bluetooth connectivity and a programmable multi-information display.
