The Toyota GZ engine is used as the powerplant for what  large four-door limousine produced mainly for the Japanese market?
Toyota Century The Toyota Century (Japanese: トヨタ・センチュリー) is a large four-door limousine produced mainly for the Japanese market, serving as Toyota's flagship car within Japan; whilst globally the unrelated Lexus LS series is Toyota's flagship luxury model outside Japan. Production of the Century began in 1967 and the model received only minor changes until a redesign in 1997. The Century derived its name from the 100th birthday of Sakichi Toyoda, the founder of Toyota Industries. The Century was available with only a V8 engine, the third Japanese built sedan post-war, at its introduction in 1967 until a major redesign in 1997, and is now only available with a Toyota built V12, an engine unique to the Century. Although the Century is a premium, full size luxury sedan, it is not available at Japanese Lexus dealerships; it can only be purchased at specifically identified "Toyota Store" locations. The logo used throughout is called the "Hō-ō 鳳凰" or "Fushichō" from Asian mythology, representing the Imperial House of Japan.
