What was the first car that was equipped with TTC in 1975 which includes the word that is Latin for "crown"?
Toyota TTC Toyota TTC stands for Toyota Total Clean System, a moniker used in Japan to identify vehicles built with emission control technology. The technology was installed so that their vehicles would be in compliance with Japanese Government emission regulations passed in 1968. The term was first introduced in Japan, with an externally mounted badge on the trunk of vehicles equipped. The technology first appeared in January 1975 on the Toyota Crown, the Toyota Corona Mark II, the Toyota Corona, the Toyota Carina, the Toyota Corolla, and the Toyota Sprinter. There were three different versions initially introduced, called TTC-C for Catalyst, installing a catalytic converter, TTC-V for Vortex, installing an exhaust gas recirculation valve, and TTC-L which used a lean burn method. As Toyota's technology evolved the three systems were eventually incorporated together in future models.
Chevrolet Opala The Chevrolet Opala was a Brazilian mid-size car sold under the Chevrolet brand in South America from 1969 to 1992, by General Motors do Brasil. It was derived from the German Opel Rekord Series C, Opel Commodore Series A, but used USA-sourced engines and Holden styling. Two four-cylinder engines: the Chevrolet 153ci 4-cylinder from Chevy II/Nova, which later got a new crankshaft stroke and cylinder bore, changing its size to 151ci (usually mistaken for the Pontiac Iron Duke engine), and the six-cylinder 250 from the contemporary line of North American car/light truck production. GM manufactured about one million units including the Opala sedan, Opala Coupé, and the station wagon variant, the Opala Caravan. It was replaced by the Chevrolet Omega in 1992, also an Opel spinoff. It was the first passenger car built by GM in Brazil by the General Motors do Brasil division. A luxury version of the Opala was marketed as the Chevrolet Diplomata.
