Allison Transmission's 9-speed automatic transmissionAllison Transmission announced it will release a nine-speed fully automatic transmission for medium- and heavy-duty vehicle markets around the globe by 2020, ahead of the U.S. Environmental Protection Agency and National Highway Traffic Safety Administration’s Phase 2 greenhouse gas and fuel efficiency standards.

The new transmission is the successor to Allison’s 2000 Series six-speed automatic transmission and uses the same interface as its predecessor. According to Randy Kirk, Allison’s senior vice president of product engineering and product teams, says the new Allison 9-Speed can achieve 7 percent greater fuel efficiency than Allison’s base six-speed model.

“This is the first in a number of new products we’ll develop to meet the global challenge of increased fuel efficiency and reduced greenhouse gas emissions,” Kirk said during a press conference at the North American Commercial Vehicle Show in Atlanta.

The control system builds on Allison’s xFE (Extra Fuel Economy) and FuelSense 2.0 with DynActive shifting features, “incorporating learning algorithms to establish new benchmarks and finding a balance between fuel economy and performance,” said Kirk.

The Allison 9-Speed features a deep first gear ratio to allow the engine to run at lower speeds sooner to improve fuel savings and a torque converter lock-up in first gear. A new engine stop-start system provides immediate transmission engagement and vehicle hold while the engine is restarted. The new transmission is aimed specifically at Class 3-7 commercial vehicles, particularly in distribution, rental/lease and school bus segments, said Kirk

Even if full electric is a long way off for heavy hauling... an electric hybrid can still go a long way toward energy efficiency and reducing the use of petroleum.

IMO the electric econobox like Prius is a bit overrated. Far more savings to be had with large SUVs and trucks.

Plenty of solar power to power all the cars electric. Solar is growing and accelerating. I am fascinated watching it progress.

An electric motor is 99% efficient. Creating, and getting, the electric power to millions of those electric motors powering vehicles all over the planet will be far from efficient. Until a 55 gallon gas tank sized battery can carry my heavy motorhome around 500 miles over hill and dale while also running an air conditioner and headlights and then be recharged at hundreds of thousands of places in 15 minutes ... I will not be impressed merely by an electric motor's conversion efficiency.

In my earlier post above I did say that neither batteries nor fossil fuel should be the final "personal transportation for general use" power solution.

If anyone wants to dispute MEXICOWANDERER's world-wide electric power generation and distribution comments relative to the difficulties/impossibilities of powering vehicles on a world-wide scale .... please have it in a point by point rebuttal.

This nonsense has been disproved long time ago..
Ask here or on any EV site

Do you know how much destruction,death and polution does diging oil from the ground create,not to mention all the wars fought in pursuit of such finite resource..

David,

Fossil fuels store a huge amount of energy per unit of volume and stations can replenish it fast. Vehicle owners can even carry their own refueling supplies via "gas cans".

I don't know what the long term "personal transportation for general use" power solution is at this point. It isn't batteries powering electric motors and it isn't CO2 coming from burning fossil fuels.

Maybe it's fuel cells fed from fossil sources or ultra-compact nuclear fusion reactors??

All that being said ... scientists do tell us that mankind is currently harvesting only a small fraction of the sun's energy that is bathing the Earth.
We've got to figure out how to bottle that energy compactly so we can carry a bunch of it around powering our personal self-driving modules.

How to bottle electric energy..
Its called bateries 😉

Where will this energy come from,,how about sun

David,

X100.

I agree completely with what you said and described above.

I have to shake my head at the electric car fanboys. They have no concept of the difficulties and overall impact in keeping charged millions of electric vehicles all over the world. They're only able, currently, to get by with their electric vehicles because they primarily use them only for local running around and because there aren't many of them.

Fossil fuels store a huge amount of energy per unit of volume and stations can replenish it fast. Vehicle owners can even carry their own refueling supplies via "gas cans".

Intertie grid failures are not "A Thing Of The Past". Total tWh to power several millions of vehicles needs a grid and sub sets beyond the comprehension of 99% of the people in this country. Three or four UHV DC transmission lines full length of California. Where's the energy going to come from, nuclear? That more translations energy goes through the more % is lost.

75 kWh to travel 275 miles is being carnival barker deceptive at its best. That is predicated @ travel UNLOADED over FLAT terrain. On a good day I will travel 500 miles. Gassing up means 15 minutes off the freeway. Not an added three hours waiting at a charging station.

Anyone ever do a workup on the energy needed to produce a Tesla and power it say, 200,000 miles? The critter is a rolling resources raper. The only viable clean energy source for creating hundreds and hundreds of tWh grids is natural gas. Would a person believe tens of millions of transmission towers and BILLIONS of feet of aluminum for conductor are going to "appear" by magic? Do any of you have the faintest idea of the amount of ELECTRICAL energy it takes to manufacture aluminum from bauxite? KISS GOODBYE your neighborhood power distribution network. It's going to need a 1000% capacity upgrade. Underground? Do your homework and see the incredible cost of underground distribution. The ONLY way this is going to be feasible is with thousand volt DC NEIGHBORHOOD system and individual inverters as per application.

I won't be around to see the insane industrialization needed for hundreds of millions of electrical vehicles. Huge asteroid impact sized open pit mines needed to extract rare earth for components, and near armaggedon when titanic electrical fields are created. Well, at least lithium pollution side-effects will moderate the manic depressive inclined.

But I will be curious to my last breath at the multiplication by magnitudes of energy needed to pull this off. Houdini advertising he can escape from a three inch thick steel steel box. At least it force the substitution for another gag for the "The magic of this gasoline saving miracle will force you to hang a bucket under your gas filler pipe"

When the reality sets in, it will initiate The Grand Crisis For Mass Transit Relief.

I will be feeding a tree.

2500/3500 use the allison 1000 not the 2000 series. 2000 series is used in at least some motorhome GM units with the 8.2 L gas engine.

Very possibly, but we need to bear in mind that GM cut Allison loose, except for the small transmissions they use in pickups, Duramax, etc. All the bigger ones, such as used in Diesel Pushers of the RV world, are from an independent Allison.

So we will likely see a 9- or 10-speed "Allison" in a Chevy 4500 Class C chassis and it'll come from GM. Probably from Real Allison in a big box truck.

Allison is a good box so long as you keep up on fluid changes and filters. Keep in mind that, the more internal ratio's available, the more complex the box becomes.

[westend]

I'm sure that's a step up from what's on the road now. A continuously variable transmission should be the goal as it's the most efficient. Material science, cost, and the weights involved may all be limiting the development of the variable transmission.
