Why a Tesla when you could have an Edison

Why would you want a Jake? The motor can put down just as much braking force as it can acceleration, and you get that power back to use again. Maybe hold off on believing marketing materials since the last BS marketing stunts from Nikola.

Certainly I've always liked the idea of a diesel electric like a train since you can tune for efficiency instead of having to run a broad range of RPMs like typical diesels, but the efficiency gains haven't been big enough to offset the downsides of added weight and engineering costs for the large manufacturers it seems. Could be they didn't want to try something new when seemingly full electric is closer and would make their engineering costs worthless in a short time span.

Who knows, but again, maybe don't trust some randos nobody's ever heard of.

 

I wonder if these were the guys who ripped off a couple who put together a few trucks about 10 years ago, they both worked for GE locomotive division from what I remember, and had made a lot of progress in making it all work. They had a couple of trucks running on the road locally for a bit of testing. One of them had cancer so everything stopped then someone came in to help just to steal all their ideas and plans.

 

So you're saying that instead of using the electric motors as a generator and dumping the heat they'll counter drive the motors and just dump the heat into the motors instead? Yeah, great idea. But it's only an issue on fully electric trucks if you have your charging depot on top of a mountain, otherwise you'll need to burn energy to get there, and get it back on the way down. I'm not saying that diesel electric hybrid trucks don't have a place, or that they're a bad idea. I'm just saying that the amount of money to produce them is probably not going to pan out long term for the large producers when they have the option to go with the well publicized electric route. Nobody wants to invest in "old" tech like diesel electric, so it's a double barrier.

I would wait for somebody other than the company who stands to gain a lot from publicity to make some videos about it.

 

Something says me you are in super excitement state.
EPA will never allow use diesel engine without crap they already put on. So, all computers, DPF, DEF, wiring, sensors will stay in place.
What is going on the top of existed crap ?
Complicated ( at least for TA shop truck mechanic) module to control electrical motor torque and speed to the wheels. All HD semiconductors need cooling, so more wires, more fans, more sensors, more heat sinks.
Just couple days ago saw yard switcher electrical truck. Daycab with small driver cab like FUSO truck with HUGE, bigger then super trucker sleeper attachment behind the cab where is battery and all electronics. Crap.
