In an era of chrome and four headlamps, the Corvette succumbed to the look of the day. The 1958 model year and the four that followed all had the exposed four-headlamp treatment and prominent grills, but a faux-louvered hood and chrome trunk spears were unique to 1958. The interior and instruments were updated, including placing a tachometer directly in front of the driver. For the 1958 model only, an 8000 rpm tachometer was used rather than the 6000 rpm units typical in 1955. Optional engine choices included two with twin carburetors (including a 270 hp (200 kW) model with Carter 2613 and 2614 WCFB four-barrels) and two with fuel injection. Power output for the highest rated fuel-injected engine was 290 hp (220 kW). Displacement remained 283 cu in (4.6 l). For the first time, seat belts were factory-installed rather than being dealer-installed as on previous models. Rare options were RPO 684 heavy-duty brakes and suspension (144), RPO 579 250 hp engine (554), 15 by 5.5 in (38 by 14 cm) wheels (404).
