Toyota anuncia cambios con 8 velocidades para su marca premiun LEXUS TOKYO — Toyota and powertrain specialist Aisin are working on automatic transmissions with "more than seven speeds," to beef up the Japanese automaker's premium products. Kazuhiko Miyadera, Toyota's research-and-development executive vice president, told Automotive News Europe the company is "looking at automatics with more speeds." He did not say when such transmissions might make it to market. Japan-based Aisin Warner, Toyota's main transmission supplier, hinted it would like to trump Mercedes-Benz and German transmission specialist ZF. Currently the seven-speed Mercedes-Benz 7G-tronic is the automatic transmission with the greatest number of ratios. "Mercedes and ZF both have seven speeds already," testing engineer Bertram Kurz said in an interview. "So there would be little point in us only doing that." More speeds would improve fuel economy and give smoother upshifts and downshifts. What this means to you: An eight-speed transmission would give a real kick in the pants to the Lexus lineup.
