Facts About the Sixth Generation
Quietness of a higher grade
For the sixth generation Corolla, efforts were made to reduce sounds that were compounded and felt in the interior — such as engine noise, road noise and wind noise — and to convert those noises into pleasing sounds. At the time, this was an uncultivated field with only a few examples of research documents, so the development team used the "Comprehensive Vibration Noise Analysis System" that had been introduced only recently in 1983. This system was formed by combining a large computer with the Fast Fourier Transform (FFT) device developed to analyze and identify submarine sounds (sound patterns). Using this system, the team could analyze and visualize eight types of sounds at the same time and could analyze the sound source in a short amount of time. Based on the analysis results, the team successfully reduced vibration from the engine and body, changed the tone of noises and created a more comfortable interior environment.
Two ranks above the class
With worldwide economic growth and the sudden growth of Japan's economy, the needs of compact class vehicles changed significantly, and a trend that focused on luxury was born. Because of this market, the highest grade models were designed with a high sense of luxury and quality that approached that of the Mark II (Cressida) class vehicle at the time. Numerous types of equipment that had primarily been used in vehicles two classes above were adopted, such as power retractable remote control door mirrors, one touch power windows, high grade moquette seats, electronic display meters and TEMS (Toyota Electronic Modulated Suspension).
