Aisin Seiki to Increase Output of More Fuel-Efficient Transmissions by 42% This Year
26 November 2007
Bloomberg. Aisin Seiki Co. says that it will increase its output of its more fuel efficient transmissions—including 6-speed, continuously variable transmissions, and others—by 42% this fiscal year.
Output of four-speed and five-speed transmissions will fall about 12% in the year ending March 31, according to President Yasuhito Yamauchi in an interview with Bloomberg.
During the next three years, Aisin’s production of three- to five-speed automatics will probably fall 20 percent, while six-and eight-speeds will increase 43 percent, according to Atsushi Ishii, a Tokyo-based analyst at CSM Worldwide. Output of continuously variable units may almost double in the period, he added.
A 1-liter Toyota Vitz fitted with a continuously variable transmission can get up to 22 kilometers per liter (52 mpg US)—12% better than using a four-speed transmission, according to Aisin.
Aisin makes the eight-speed automatic transmission for the Lexus LS460 sedan. The unit gives an 11 percent better performance than a five-speed version, according to Aisin.
In addition to Toyota, which holds a 22% stake in Aisin, the company’s other major customers include Volkswagen AG and General Motors Corp.
Aisin plans to raise its research and development spending 9 percent this fiscal year as it explores new technologies including dual-clutch transmissions and lightweight materials. Research spending will equal 113 billion yen, or 4.2 percent of sales, this year, according to the company.

If CVT, and/or 6 & 8 speed transmissions can increase mpg by as much as 12%, why wasn't it years ago?
Plentiful & Cheap fuel?
Coupled with improved fuel injection + stop/start + low friction tires, one may get as much as 20% mpg gain at very little extra cost.

CVTs & 6 to 8 speed trannies years ago? I don't think so. I waited for a cheap reliable CVT for 16 years. Such CVTs were unreliable in 1990(Subaru Justy). Your 12 to 20% MPG increases are only numbers you presently mention & certainly weren't available in the past. You have to let technology advance till its practical technology.

I hope projected MPG increases for these transmissions will be more accurate than the MPG increases predicted for present CVTs in lots of cars today. CVT owners in several brands are not getting the 6% MPG increases they were told would be theirs. My Dodge Caliber CVT averages 31.4MPG only because I have less stop & go traffic than others & I feather foot like crazy. The vast majority who love the CVT smoothness, do not get good MPG.
