The fourth-generation Accord, introduced on the "CB" chassis, was unveiled in 1989 for the 1990 model year. Although much larger than its predecessor, the sedan's styling was evolutionary, featuring the same low-slung design and wraparound rear window as the third-generation Accord. For the first time, a 3-door hatchback was no longer available internationally.

This was one of the first U.S. production cars to feature optic reflectors with completely clear lenses on the headlamps. The styling reflected influences from the flagship Honda Legend (sold in North America as an Acura), as Japanese Accords were now sold at Honda Clio dealerships, where the Legend, and the Honda Inspire, were sold. The growing popularity of the Accord internationally was evident in the ever-increasing dimensions, which now matched almost exactly with the first-generation Legend introduced in 1985.
