also, it sounds a little rude.....  I'm not sure I want to look at Tesla's semi thank you very much.

[Externet]

And I wish to understand English ... What is semi ?   A partial or half something truck ?  Who comes up with those words ?

Yes - partial or half something....    it also gets used to mean a partial erection, thus my comment about not wanting to see Tesla's. ;-)

This is a somewhat impartial look at specs:

I'm hoping the speed up 5% grade and the range are also done with an 80k lb load like the acceleration test.

In Phi's picture, the front end is the tractor, and the back end is the trailer. A tractor-trailer.

This type of trailer has no front wheels and is thus only a 'partial' or 'semi' trailer. It must be pulled by a tractor which essentially provides the front wheels for the trailer.  Because it is a semi-trailer, people started calling that type of tractor a semi-truck.

When people say 'semi' they may be referring to the tractor, the trailer, or the combination of both.

I'd always heard they called them that because of the coupling (settle DOWN, DrP!). The truck breaks apart, and the tractor can operate separately from the trailer. Semi-detached, maybe?

edit: x-posted with zapatos, and I think his description of the semi-trailer (not having all the wheels necessary to operate independently) is the most likely source of the term "semi" for big-rig trucks.

On another note, while I support and applaud the efforts here to move away from petroleum powered trucking, I only semi-care about the origin of the term... aka: etymology

The stats are pretty impressive. If it performs as promised, diesel trucks will disappear as fast as Tesla manages to make these trucks.

Until our electricity network breaks down, of course.

[HB of CJ]

Written English containing slang or colloquial words can be difficult.  I do not know if that was the intent.  Semi in this case means a large tractor trailer freight hauling highway truck.  Big.  Up to 40 US tons in the USA.  Up to over 50 tons in some USA States.  Like most advertisements the performance specifications may be somewhat .... expanded or stretched or expounded.

Example.  The performance stated might have been achieved under perfect conditions.  Not usual conditions.  An Example ... in stop and go very slow congested urban traffic during hot humid summertime conditions the cab air conditioning wattage requirements may exceed the traction motor wattage needs.  Other examples probably abound.  But ... a great first step.

Electric vehicles are the next generation.  Super efficient cascading electric capacitors?   Once we achieve that then probably electric hydrogen fuel cells will be next?  After that who knows.  On dedicated long haul routes electric trucks may work very well.  In stop and go city applications, probably not yet.  Perhaps a ROBO TRUCK electrically powered will be in our future?

Therein lies the key variable given Tesla’s long history of production delays and missed delivery deadlines. People who preordered a Model 3 three years ago are apparently still waiting, too

I’d like to see us overlay roadways and highways with ambient chargers (like used w electric toothbrushes and wireless phone chargers) that themselves get loaded via solar cells. As long as one is driving over it their system is seeing net energy gains (not charge depletions). 

Too bad we’re too dumb to put people to work via such smart and scalable Eisenhower-style infrastructure investments.

Like this?

Too bloody right, they block my signal. Besides, I see a business opening for chic, portable oxygen cylinders when the oxygen levels get too low.

An HGV is a different classification and need not be articulated.

Of course the term is made more difficult by the american pronunciation of the part word 'semi'.
