Replacing the old I-Mark, Isuzu's subcompact Stylus sedan arrived in late spring of 1990, as a late '90 model. In the same year, Isuzu launched a sporty Impulse coupe, built on the same front-drive chassis. A 95-horsepower, 1.6-liter 4 cylinder engine went into the base S model, with either 5-speed manual shift or a 3-speed automatic transmission. Stepping up to the XS sedan brought a 125 horsepower dual-overhead-cam engine, as in the Impulse coupe. Only manual shift was offered in the XS. The Stylus S sedan had 13-inch tires, standard manual steering, and front-disc/rear-drum brakes. Power steering, all-disc brakes, 14-inch tires and a firmer Lotus-tuned suspension went into the XS sedan.
