GM, Ford work on 9-speed, 10-speed transmissions: report

Reuters -- DETROIT (Reuters) - General Motors Co (GM) and Ford Motor Co (NYS:F) are jointly developing nine- and 10-speed automatic transmissions to improve the fuel economy of their models, Automotive News reported on Friday.
GM, the largest U.S. automaker, will lead the design of a nine-speed gearbox for front-wheel drive vehicles, the publication reported citing people familiar with the matter.
No. 2 U.S. automaker Ford will head the effort to develop the 10-speed transmission for rear-wheel drive vehicles such as pick-ups, SUVs and performance cars, Automotive News reported.
GM and Ford could not be immediately reached for comment.
The auto industry is scrambling to find ways to boost fuel economy by 2025, when U.S. government standards mandate that automakers show a corporate average fuel econom

MAC48 Champion Author Dallas Posts:1,546 Points:763,220 Joined:Dec 2006	Message Posted: Sep 29, 2012 11:59:35 PM Ignore MAC48 Report Abuse One has to wonder how much 9 and 10 speed trasmissions will add to the initial cost and maintenance cost of a vehicle. If there is no additional inital capital cost or subsequent maintenance cost compared to what we have today in the majority of vehicles, then why not expand the speeds ranges that a transmission operates at if it indeed will improve the fuel efficiency of the vehicle.

The top gear in the Vette allows fairly good acceleration without down shifting, going to a lower rpm would require a quick down shift if you wanted to speed up. The owners manual has a bit on not getting to 6th below, I think, 43 mph which is just below 1000 rpm. If they had a 7th gear that you didn't hit until 65 or 70, mileage would improve. Torque is not the issue here but torque and wind resistance is significant. That's why top speed on the Vette is in 5th and not 6th gear.

Your TDI Volkswagen's drivetrain is engineered for max mpg with its current final drive ratio.

StArrow68 Champion Author Oakland Posts:3,237 Points:1,357,240 Joined:Apr 2003	Message Posted: Sep 29, 2012 1:03:28 AM Ignore StArrow68 Report Abuse I like the concept. Having had the benefit of a 6 speed with double overdrive for the past decade I can see where it would benefit. No, rowing gears in a manual in heavy traffic isn't fun, but with auto these would keep rpm's to a minimum which is what I can do in my Vette, if I choose, :). In 6th I can cruise at 1500 rpm at 70 mph and get mid 30's for mileage. If on long trips I had the option to get that down around 1000 rpm it would be a big benefit.
