The Chrysler 300 will be a recipient of the new 9-speed automatic transmission.
A 16% improvement in fuel efficiency is expected from nine-speed transmission

Automakers are pulling out all the stops and looking to squeeze every single mile per gallon out of their automobiles by any means necessary. Automakers are looking at more fuel-efficient engines with smaller displacements, but they're also looking at reducing the weight of vehicles and increasing the number of forward gears used in car/truck transmissions. 
Adding forward gears to a transmission makes a lot of sense because the slower the engine spins, the less fuel it consumes. In years past automatic transmissions used in vehicles commonly had four or five forward gears. More recent vehicles are moving up to six-speed and in some cases even eight-speed automatic transmissions in luxury vehicles. Chrysler is eyeing even more gears inside with nine-speed gearboxes for more mainstream vehicles.
According to Mircea Gradu, vice president transmission powertrain driveline engineering, Chrysler will roll out its first nine-speed transmission by the first half of 2013. “I’m convinced that, sooner or later, others will come up with similar solutions,” Gradu said in an interview from his office in Auburn Hills, Michigan, where Chrysler is based. “Hopefully, the time will be as long as possible until they catch up with the technology.”
Chrysler CEO Sergio Marchionne believes that the automaker and its various brands will be able to meet looming fuel-efficiency standards by using technology that improves traditional gasoline engines combined with better transmissions rather than moving to plug-in hybrids and pure electric vehicles. CAFE standards will reach 54.5 mpg by 2025.
Michael Omotoso, a powertrain analyst at LMC Automotive, said, "They’re [Chrysler] doing basically the bare minimum to satisfy government regulations. Their strategy is to meet the standards with minimum investment.”
Bloomberg reports that the nine-speed transmission Chrysler is developing could boost fuel economy of certain models by as much as 16%. Chrysler has already scored a 15% boost in the highway fuel economy of the Chrysler 300 and Dodge Charger by adding an eight-speed automatic transmission.

You can perfect it all you want but it is still an annoying pain in the ass to shift gears all the freaking time.

Only if you're lazy, wolfing down cheeseburgers and can't get your cell phone out of your hand nor resist the urge to text and drive. Having to shift makes you pay attention and stay focused.

Actually, I am lazy. And that's a pretty good reason for wanting an easier drive to work. I can easily afford the difference in gas that I would have saved with a manual transmission. It's well worth it when it can take 20 minutes to get to work on a good day, 1.5 hours on a bad day.

As an aside, I gave up the manual when I had to make the evacuation during the Houston Hurricane Rita scare. Houston to Dallas is, normally, a 4 hour drive. It took 27 hours that day. You have no idea how painful it was to have a manual for that trip. Stop and go traffic, with a max speed of about 5 mph, for almost 24 hours is pretty much how I imagine hell.

haha Of course it is, that was the point. The real argument was that I like being lazy. Which is a perfectly sound argument that I am far too lazy to expand.

That's ridiculous. It's not being lazy to let a machine do the work for you. I suppose those that aren't lazy are just jogging to work eh? Or at least get rid of your power steering too?

A manual transmission makes no sense whatsoever except for two situations:

Vehicles that have to haul heavy loads, in which case a sacrifice is made to go with the manual.

Idiots that think they are boy racers on public roads and need to feel more in control of their car by doing the shifting themselves.

Nothing else is good about manual transmissions except the lower cost.

So all of us manual drivers are just idiots. Don't you think that's just a little extreme? I'm not in the habit of calling people idiots because they prefer to do something I don't. We all have our differences and I'm perfectly fine with that. What's your problem?

If you had the choice of an auto and went with a manual for a passenger vehicle on public roads other than to save money or haul loads, yes.

How are you perfectly fine with our differences if I prefer to call something idiotic and you don't? Seems like a double standard to me. To withhold speech in order to create the illusion of a touchy-feely world has its downsides. If you own a manual because it makes you feel like a boy racer, you might as well know that some people out there think that's idiotic.

Perhaps you have another reason for owning one, I meant only what I wrote and used a non-slang word with a proper definition in any dictionary. Shall I no longer have thoughts that disagree or is it that I'm not allowed to express them if they differ from yours?
