Although trucks are highly regulated they also happen to be a lot easier to use a platform for this kind of experimentation. For one an extra 1000 pounds isn't going to impact performance (though it will reduce freight capacity). Some truckers tell me just ice and snow can add a couple of thousand pounds to their trucks in the winter. Anyway plenty of room to play around with different drive trains and power systems, which is what this company seem to have done.
I've always been skeptical of hydrogen as a means of of energy storage, but if the numbers are right this is pretty good, for a range of about 800 miles. 1000 hp and 2000 ft-pounds of torque are definitely good numbers for a class 8 truck. The truck I drive sometimes is only 500 hp and 1800 ft-pounds of torque, and pulls 63500 KG GVW (only on flat roads and not fast). So this should easily go up and down mountains. And with no transmission to shift, the power will be smooth and efficient. I'm thinking they've had their prototypes on the road for some time now, so it will be interesting to see how quickly they can really bring this to actual market (start leasing them to real drivers and real companies).
The articles I've read don't talk a lot about how the refueling is done and pouring liquid cryogenic fluids is pretty dangerous. So we shall see. And we don't know much about other details like if the drive train can act as a big engine brake. It's pretty funny how the media reacts to things like this. Instead of focusing on the truly interesting aspects of the truck like the power cell and drive train, they focus on the cab and how it has a nice sleeper with a microwave oven! Hilarious.
Anyway, coming from someone who actually has a CDL and drives trucks on occasion, I'm quite interested to see where this goes.
