The Corona became massively successful in export markets: confusion easily arises because Toyota (like Volkswagen with their Passat and Mitsubishi with their Colt) applied model names inconsistently in different places. Following the 1969 parallel introduction of the Corona Mark II (which in certain markets mutated into the Cressida in 1973) there were disparate models sharing the Corona name. As time went by, models branded in much of Asia as Coronas turned up in European markets as Carinas, while ten years later in North America the Corona was successfully replaced by the larger Camry. In addition, because of the similarities in names, it is a very common mistake to confuse the Corona with the much smaller Toyota Corolla.
The first generation Corona was designed with parts from the previous generation Crown and Master, due to a major restyle and enlargement of that model. Many of the body panels were cut down from the Master that ceased production. Also available was the ST16/PT16 van versions. The 997cc (60.8cuin) OHV P series engine was used, but the regulations regarding taxi's at the time were 910cc (56cuin). Dealers restricted the power for taxi vechicles. Due to the upgrade in dimensions of the Crown, Toyota needed to continue manufacturing a vehicle with similar size dimensions to the first Crown, primarily to be used for taxi usage. This vehicle saw the introduction of a monocoque chassis structure, and a independent front suspension using double wishbones. Due to the monocoque chassis, Toyota was able to produce a vehicle under 1,000kg (2,200lb). This series was only available as a four door sedan. Due to improvements indroduced in 1959, this car was capable of traveling at 105km/h (65mph).
The Tiara was a series of sedan models sold by Toyota Motor Corporation, as an export model of the Toyota Corona. It was introduced at a critical time for the company in North America. Their first flagship car, the Toyopet Crown, was unsuccessful in the US market, and was withdrawn, leaving only a single vehicle, the Land Cruiser. At the time, there was little market for an off-road vehicle like the Land Cruiser. The front end styling is reminiscent of the 1955-1957 Ford Thunderbird.
