Derived from the 1990-93 Honda Accord sedan, but on a longer wheelbase and sporting frameless door glass, Vigor filled the gap--in both size and price--between Acura's entry-level Integra and the luxury-flagship Legend. Vigors came in two price levels: base LS and upscale GS. All-disc antilock brakes and a driver-side airbag were standard from the beginning. Beneath each Vigor hood sat a 2.5-liter 5-cylinder engine, hooked to either a 5-speed manual gearbox or optional 4-speed automatic transmission.
