Arrival Limited delivery vans are nice and smooth looking, but sort of blocky, no tapering of the roof or sides.

Right after I did my city truck rant, I had the idea that the electric Cummins could be more of a suburban delivery vehicle. With jumping on the highway doing 70mph, followed by going down secondary streets at 45 mph and zipping into a big box parking lot, and never hitting a 25-35 mph zone.

Aerodynamics could play an important role in a suburban truck.

Still puzzled by the 5th wheel trailer aspect.

Maybe there is a new transportation hub to go with it, featuring pre-loaded trailers, a route laid out by computer and so forth.

COE:

A ***** to climb in and out of multiple times daily. Dangerous when wet or icy

Terrible engine access

Terrible crash protection

Terrible ride.

Some forward-control trucks have their cabs set actually in front of the engine instead of over it, which makes it easier to climb in and out, but they're still mostly found on special applications such as aircraft ground support, heavy cranes and fire engines.

Engine access is not so bad at all on most tilt-cab trucks, and actually neither in those small Asian trucklets that have just an under-seat hatch for engine access.

That's a downside, but it doesn't prevent COE trucks to become prevalent in a worldwide basis nowadays.

slowmover basically nailed it.

I would just like to add:

COE - Cab Over Engine.
"Where the driver is the first one at the scene of an accident"

Conventional cab - Where I have my 3200+ pound Cummins X15 engine between me and the crash.

GOE - My new, almost finished truck, is actually a new hybrid cab design I call a GOE, or Glass Over engine. It's actually based on a conventional rolling chassis. Can't wait to post it here, but it will be a while longer.

I don't know about anywhere else, but the only reason they are prevalent in Europe is their super restrictive overall length laws. But those length laws are changing and one will eventually see conventionals in Europe.

Sounds like driver safety is on the table, rare to hear of a truck driver not surviving an accident but it happens.

Cummins Looks to the Future: Unveiling First Electric Powered Semi
September 1, 2017
http://capitalremanexchange.com/cumm...i-ahead-tesla/
Cummins Talks AEOS All-Electric Truck, X12 & X15 Diesel Engines
Quote:
The AEOS’s heart is a 140-kilowatt/hour battery pack, weighing about the same as an equivalent 12-liter drivetrain. It has a GVWR of 75,000 pounds and can go about 100 miles on a single charge. With supplemental battery packs, it can add on an extra 200 miles of range. Its payload is 44,000 pounds, and the tractor weighs 18,000 pounds.
I'm going to guess that the battery pack runs the length and is of platform design.

Maybe some electric controllers are under the hood, electric motors would be perpendicular to the wheels is my guess.

In short, weight/mass wise the AEOS’s will behave pretty much as a COE would is my guess.

If any one finds a cut-a-way or layout diagram please post it.

Quote:
The new engine system is known as the AEOS Engine, named after Greek mythological hero, Helio’s favorite horse.......................

The new AEOS engine is designed for cartage transportation and has a 100 mile operating range. Cartage trucking mostly specializes in the distribution of freight in a radius around major metropolitan areas or shipping ports. Examples of Class 7 Trucks would be food or package delivery vehicles ie.. (UPS or Bread Trucks.).......

Also in 2020 Cummins will have an extended version available with a small diesel engine which will act as an on-board generator for the batteries. The new low emissions diesel hybrid will be able to go 300 miles between charges and offer 50% fuel savings compared to the diesel hybrids on the market today. The company is researching the viability of adding solar powers to the top of the truck to further produce energy on the fly......................

The company embraced the shift from 2-Stroke to 4-Stroke diesel engines instead of going under. In recent years the industry leader has been a pioneer in environmental issues and diesel particulate after-treatment systems for all of its engines. Rival Caterpillar Inc. decided to exit the over-the-road trucking industry in 2010 after failing to adapt to changing emissions regulations....................

Only time will tell what the future may hold for the electric engine in the over-the-road trucking industry. With the advent of change it forces a premium on faster pace adaption. Innovation and advancement are built on the rapid need to adapt to survive. Cummins seems to not only understand this concept but embrace it. Eventually, one of these newer companies will figure out a long lasting battery to harness great amounts of energy in a compact space. As technology progresses it will be up to the manufacturers, companies and ultimately the drivers to keep up with the changes. Those who do not adapt will go the way of the dinosaurs. Greek philosopher Heraclitus said it best, “All is flux, nothing stays still – there is nothing permanent except change.”
I did a lot of guessing on the layout, I'd rather have some pictures - trust me.

EDIT:
After considering the projected 2020 hybrid version I quoted earlier, I'm forced to assume there isn't much in the way under the hood. Even a smaller Diesel generator is going to take up some space, and where better to put it?

It's safer to be a fireman, policeman or soldier in peacetime than a truck driver. Note all those others have huge job benefits and guarantees.

Worse is logger, fisherman , farmer and rancher. Same bad job benefits.

But those aren't important to a national economy, right?

Dominated by women, anyway. That glass ceiling thing not existent.

You've experience in heavy COE? Ha!

Lost me at the segue. But that's the thing men's rights advocates are on about.

My experience in 'first to the scene' was in a Type II panel van (uprated from 1/2ton to 3/4ton axle). Engine access was good, step-in height was good. It would top the Coast Range empty at 75mpn, but at least if you go off the road it's tail first.

When I was college age I had a International tilt-cab box van with 5 ton of diary feed in back sideways on gravel roads. For the lulz.
