Automakers hope to save millions of dollars with joint development

Ford and General Motors have announced that they have teamed up to jointly develop a new generation of advanced 9- and 10-speed transmissions that will be used in cars, crossovers, SUVs, and trucks.
The automakers say that the new transmissions will increase both performance and fuel economy. Engineering and development work for the transmissions is currently underway.

“Engineering teams from GM and Ford have already started initial design work on these new transmissions,” said Jim Lanzon, GM vice president of global transmission engineering. “We expect these new transmissions to raise the standard of technology, performance and quality for our customers while helping drive fuel economy improvements into both companies' future product portfolios.”

Automakers need every edge they can get to meet the looming federal CAFE guidelines set to go into effect over the next several years. With a greater number of gear ratios available in the transmission, the engine can operate at more efficient RPMs, which in turn leads to improved fuel economy.
Some industry analysts believe that a nine-speed automatic transmission could increase fuel economy by five to ten percent compared to the same vehicle using a six-speed transmission.
The two companies have collaborated on transmission technology in the past. Ford and GM previously collaborated to build a six-speed transmission for front-wheel drive cars. Ford currently uses the six-speed transmission and vehicle such as the Fusion and Edge. GM uses the transmission in the Malibu and Cruze among others.
Chrysler is currently using an eight-speed automatic transmission in some of its automobiles, including its popular line of trucks.

All this talk about CVT seems odd to me after reading about Paul Pires' geared IVT Infinitely Variable Transmission developed a couple decades ago. His IVT is used in a heavy diesel tractor with lots of torque, it doesn't have CVT's shortcomings and sounds better than even 10 gear autos.

It seems like auto companies only want to use solutions they own the rights to, even partial rights, so long as they are "good enough", to hell with what works best...

Paul Pires' solution to creating the geared IVT is actually quite ingenious and cross-specialty in nature.

Below is a link to the Aug 1992 Popular Science article that introduced me to Paul Pires (Epilogics Inc.) IVT years ago, plenty of pics too; thanks go out to Google-Books:
