Sure sounds like the right stuff to me. Compare maintenance free for five or ten years, low fuel costs. It makes sense:

https://www.tesla.com/semi

UPS bought a bunch for a trial, that will be a good test.

Maintenance free for 5-10 years? Really?

Are you familiar with the physics associated with Li-on battery life? How many charge cycles does a typical Li-on battery pack undergo during its lifecycle?
How many miles will a Tesla Class 8 semi go before its battery pack has to be changed out? How much will it cost to replace the battery pack? How many miles does a typical long-haul class 8 heavy truck operate per year?

Instead of relying on Elon's hype machine to provide these answers do a little research.

I guess Elon's next project will be a Li-ion powered 767? I'd also bet he'd get someone to put down a deposit on one.

Elon would be proud of your claim.

This will either succeed in the market, or not. Don't worry about problems above your pay grade.

Aside from the battery, near zero maintenance over the lease cycle is why GM killed and recalled almost every EV1, there was no support in it for their dealers.

Psyshow did a great video on these... it's all about the road load capabilities...https://youtu.be/oJ8Cf0vWmxE

Batteries have weight, and trucks have a finite amount of legal road surface capacity.
The truck could do the haul, but the cargo capacity would be seriously degraded, not economical with current battery twch.

This isn't true.

The real reason why GM killed their electric car was because other GM was on the verge of making a killing on CARB credits at the expense of every other automaker.

The other automakers convinced CARB to lessen their requirements because they were too strict. In reality, they all knew they were going to be paying oodles of money in carbon credits to GM and weren't happy.

The Air Resource Board assumed GM, after spending a ton on research, were going to take one and release it anyway.

Instead, GM killed the vehicle. Without the income from the carbon credits, GM didn't stand to make nearly as much money form the research. Maintenance from dealers wasn't even in the picture.

That documentary, "Who Killed the Electric Car" is a fun one to watch and is surprisingly modest in its angling for a 2006 documentary.

IMHO, battery vehicles are a stopgap technology before we have a better fuel source for the future.

Who knows... with the carbon footprint and the reduction in maintenance, the charge time could be an issue, but losing 10 tons of cargo capabilities could be the biggest issue...

For a new technology I think that's pretty good. It's funny so many people bet against the first Tesla's back in 07 and 08, Bet against SpaceX 5 years ago, bet against pay pal 20 years ago. Do you really want to bet against Tesla now?

I think by the time Tesla trucks become a major played in the truck industry, the vast majority will be self driving. Tesla has been working on the technology for years and most trucking companies will happily give up a few tons of cargo in favor oflower fuel cost and zero driver costs.

Wishful thinking.

Perverse incentives, like the biofuel mandate that let to the burning of indonesia to plant jatropha palm.

And yet another non German diesel joins the US market.
The 2019 Hyundai Santa Fe Will Be An Upscale Family Hauler With Diesel Power

The exciting news is that the Santa Fe will also be available with a 2.2-liter turbo diesel four-cylinder rated to pump out 200 horsepower and a healthy 320 lb-ft of torque.

Still quite a few CPOs out there

https://www.mbusa.com/mercedes/cpo/inventory/zip-29229/class-E:SDN,GLK:SUV,M:SUV/fueltype-D

Adjust the zip code in the link in to center the search where you are...

I am curious, if this does blow up in MB’s face, are they going to force me to turn in my 2014 BT? What happened with VW/Audi, anyone on the board affected by this, did they force you to sell back your car or just give you an offer you couldn’t refuse.

I’m hopeful a compromise can be worked out. I think the rules were made impossible on purpose so that there would be no reasonable way of complying, to force diesel out of the market. A shame. It really is a superior engine technology.

80 K is apparently the all up weight, actual payload matters. However, the electric motor would be lighter than the diesel engine and trans should be able to be eliminated or replaced with a lighter 2 speed unit. Take away the weight of diesel fuel and the battery weight might not be as great as first thought.

500 mile range is 7.6 hours of 65 MPH. A CDL driver is legally able to drive 11 hours so this 500 mile range won't do it for a long haul truck.

The electric truck would probably work out as an in city delivery vehicle.

Due to wind resistance and tire friction, I'm thinking it costs more $ / energy per mile to move 1 Lb in a big truck than 1 Lb in a Tesla car. I don't have any real numbers to put against that however.

As for orders, unless these companies have paid full cost they are just paper orders. If there was a govt rebate this leans towards green washing.

In town electrics would likely win, over the road I don't think so. It isn't about a viable electric motor / controller , it is about a high energy density / fast charging battery. Solve this and electrics become as viable as a 50 Hp electric motor running a stamping press in a factory.

It depends on volume. For example, moving 2 people in a small car is far more efficient than moving 2 people with a big truck. However, when the goal is moving 68 people, a school bus (big truck) is far more efficient than using 17 cars at 4 people per car.

Freight is no different. Moving 1 lb vs. moving 50,000 lbs.
