As a unique entrant in the half-ton pickup truck segment, the midsized Honda Ridgeline provides a number of innovative and industry-exclusive features. It has an in-bed trunk of 8.5 cubic feet, a smooth and responsive four-wheel independent suspension, and standard safety equipment including side curtain air bags and vehicle stability assist (VSA). For 2008, a new wheel design with "machined styling" appears on the Ridgeline RTS and RTL; while the fabric interiors of the RT, RTX and RTS have changed from dual-tone to a more contemporary single-tone style. The Honda Ridgeline is available in four trim levels: RT, RTX, RTS and RTL.
