The fourth generation Prelude was a radical break from the traditional Prelude shape -- the rectangular, notchback body was replaced by a shorter, lower, wider fastback. Under the hood, the top-of-the-line Prelude Si received a new, 160 hp, 2.3-liter, fuel-injected, DOHC engine. Combined with a well-matched 5-speed gearbox, the new car accelerated to 60 miles per hour nearly two seconds faster than the third-generation cars. A new, electronically controlled four-wheel steering system returned as an option. The Prelude S shared the same chassis and underpinnings, but used the 135 hp, SOHC engine from the Accord and rode on smaller, 14-inch wheels. In 1993, Honda added the Prelude Si VTEC (later, simply Prelude VTEC) to the U.S. market, giving Prelude fans 190 hp H22A engine that Japanese-market Preludes introduced the year before. In addition to the more powerful engine, these cars had upgraded interiors and slightly larger front brakes, but were otherwise identical to 2.3-liter Si. In 1994, Honda made minor interior changes to interior lighting and the center console. The 1995-only Prelude SE was simply a 2.3-liter Si with the leather interior and improved stereo from the VTEC. The four-wheel steer option proved unpopular in the U.S., and was no longer offered after 1994. The fourth generation cars made Car and Driver's 10-Best list every year of production, and it placed highly in several sport coupe comparison tests. Total fourth-generation production for the U.S. market was 98,627.
