Introduced exclusively to Japan in July 1990, the Camry V30 carried forward the four-door sedan and a differently styled hardtop sedan. Like before, either shape could be had in a Vista branded variety with revised styling. Both bodies would also form the basis of enlarged wide-body XV10 versions from September 1991, aimed primarily at international markets. The V30 remained smaller than the XV10 to offer buyers a vehicle within the "five-number" registration category concerning exterior dimensions and engine displacement for Japanese vehicle size regulations. The rules required a body width under , length under , and engines at or below 2,000 cc. Sedans in the wide-body format would sell overseas as the Camry XV10—identical to the smaller V30 in most respects except for the front- and rear-end styling grafted to an otherwise unchanged body and interior. Hardtop sedans would engender the luxury Lexus ES 300 (XV10), which again would couple the existing side profile with rehashed front, rear, and interior designs. The export-oriented ES 300 would sell as the Toyota Windom in Japan. Dimensions grew slightly with sedan body length extended to , and for the Vista and Camry hardtops to , respectively. Penned by Osamu Shikado, the V30's design is much rounder when compared to the V20 series. Sedans purge the V20's six-window greenhouse for a four-part setup with integrated window sashes. Up front, the sedan's curved headlamps converge with a slimline grille insert; hardtops get a thinner front assembly with narrower lights, and the C-pillar is raked more sharply. Base cars gain full body-colour coding of peripheral exterior components. The four-wheel strut/coil suspension carried over from the V20, although as option on high-end front-drive trims, Toyota added a wheel-stroke-sensitive Toyota Electronic Modulated Suspension (TEMS) and speed sensitive four-wheel steering. The available powerplants were three twin-cam inline-four engines—the 1.8-liter "4S-FE", plus the "3S-FE" and higher-performance "3S-GE" 2.0-liter units. Toyota also made available the 2.0-liter "2C-T" turbo-diesel inline-four, and for the flagship Camry Prominent only, the 2.0-liter "1VZ-FE" gasoline V6.
