Claims mean nothing. I want to know what the cost per unit is going to be and maintenance costs when they ultimately arrive.
Guys this is a pretty basic setup, and it it does boost fuel economy by 30%. The cost of maintenance can be larger and still be cost beneficial.
By the description this doesn’t sound like a complicated system at all. Battery some motors and a few sensors and some code. Batteries probably add some weight to the trailer which may reduce the overall cargo it can carry but even that is likely marginal relative to fuel gains.
Definitely sounds like one of those “why didn’t someone think of this before” inventions. If the fuel gains are anywhere close to what is claimed this will likely be standard on most trailer in a short period of time, at least for the bigger fleets.
So now the driver has to makes stops every 150 miles and sit for 2hrs while the trailer recharges?
