Op basis van de Daimler Freightliner "gaat" Tesla efficiëntere trucks maken (ttz zuiniger en milieuvriendelijker).
De
Daimler Freightliner is een diesel-electro hybride vrachtwagen die 12-MPGe verbruik haalde of 115 % beter dan de gemiddelde fossiele vrachtwagen Class 8. Tesla denkt zelfs aan een volledig electrische vrachtwagen...
(voor korte afstanden) (mi eerder een plug in hybride waar een fossiele motor de accu´s op de nodige capaciteit houdt, vb turbine:

In elk geval zijn al talrijke ingenieurs van de Daimler-vrachtwagen ingehuurd door Tesla voor het
Tesla Semi project.

The US Department of Energy (DOE) has an initiative called “SuperTruck”. Under the program, the DOE gives significant grants to truck manufacturers to increase the fuel economy of medium- and heavy-duty vehicles by developing new technologies.
Daimler is one of the truck manufacturers taking the most advantage of the program. Under the first version, it developed the 12-MPGe Freightliner SuperTruck, and it recently announced that it won $20 million out of the DOE’s $80 million in grants for the second round of the program – appropriately named ‘SuperTruck II’.
Electrek has learned that Tesla hired several key engineers who previously worked on Daimler’s SuperTruck program, which is particularly interesting now that we know Tesla is working on its own truck: ‘Tesla Semi’.
We know that Tesla tapped former Model S Program Director and Daimler’s Cascadia GM, Jerome Guillen, to lead the ‘Tesla Semi’ project. Before joining Tesla in 2010, Guillen was a longtime Daimler executive and he led all new Class 8 truck development at Daimler Trucks North America in Portland Oregon, where the company was working on the ‘SuperTruck’ and is now presumably working on ‘SuperTruck 2’.
Over the past year, several engineers from the program joined Tesla, most recently Evan Chenoweth, who worked on the design of Daimler SuperTruck’s hybrid engine since the inception of the progran, has joined Tesla last month as a Sr. Mechanical Design Engineer.
Daimler’s Freightliner SuperTruck achieved a 12-MPGe with an 11-liter diesel engine paired with an electric motor, which is about 115% better than the average Class 8 truck on the road today. Tesla is aiming for an even more significant improvement.
While most companies working on the DOE’s SuperTruck program focused on hybrid powertrains or on increasing efficiency, Tesla is believed to be working on an entirely battery-powered truck.
The development of an all-electric truck would certainly fall under the requirements for ‘SuperTruck II’ and the DOE has yet to assigned all $80 million in grants for the second round of the program. Tesla didn’t answer inquiries about whether or not they applied for the program with their ‘Tesla Semi’ project.
Back in June, Tesla CEO Elon Musk described Tesla Semi as being in the “early stages of development”, but he also said that we should expect an unveiling of the concept in the next 6 to 9 months.

Er circuleren al een tijdje fantasiefoto´s hoe zo´n Tesla Supertruck 2 er zou kunnen uitzien:

An interesting concept is that Nikola Motor Company plans to have network of its own CNG stations. Trevor Milton, Founder, CEO and President, Nikola Motor Company said:
“The fuel will be delivered through Nikola’s own gas wells and fueling stations in every state when trucks enter service. We will be the first manufacturer of class 8 trucks that is vertically integrated from well to wheel.”
The Nikola One’s electric motors are powered by a liquid cooled 320 kWh, lithium-ion battery pack (over 30,000 lithium cells), which is charged by a proprietary onboard Nikola Motor Company turbine. The turbine automatically charges the batteries when needed and eliminates the need to ever “plug-in”. The turbine produces nearly 400 kW of clean energy, which provides ample battery power to allow the Nikola One to climb a six percent grade at max imum weight at 65 mph. A typical class 8 diesel truck under similar conditions would have a hard time reaching 35 mph. And going downhill, the Nikola One’s six electric motors absorb the braking energy normally lost and deliver it back to the batteries, increasing component life, miles per gallon, safety, and freight efficiencies while eliminating noisy engine brakes and reducing the potential for runaway trucks.

De vele truckers mogen ook eens naar iets uitzien, vooral het vermogen- koppel -bij hellingen- is onklopbaar, 6% hellingen kunnen aan 105 kmh genomen worden ipv 50-55 kmh.
Bergaf kunnen de accu´s opladen, ook de remmen zullen veel minder belast worden door het recuperatief remmen via de electromotoren.
