All three trim levels of 2009 Ridgeline- RT, RTS and RTL are powered by a 250 horsepower 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 throughout the new Ridgeline line-up. But, RT is equipped with 17x7.5-inch steel wheels, while the same size wheels upgrade to alloy on RTS. P245/65 R17 all-season tires are standard on both RT and RTS. The top-of-the-line RTL comes with 18x7.5-inch alloy wheels and P245/60 R18 all-season tires. A tire pressure monitoring system (TPMS) and a tow hitch come as standard equipment on every 2009 Ridgeline models. A 7-pin wiring harness is included on RTS and RTL only.

Inside, all Ridgeline trims come with many standard features, including power windows & door locks, cruise control, a column-mounted shifter, and air-conditioning. Further, RTS and RTL trims add dual-zone climate control and power lumbar support for the driver's power-adjustable seat. For 2009, all audio systems are MP3/WMA compatible. However, RTS adds an auxiliary input jack to the audio system. RTL models get a handy 115-volt AC outlet. A six-speaker, 100-watt audio system comes standard on RT trim.
