Their claim that typical modern diesel tractor has only a 500 to 750 mile range is about half of reality and very few modern diesel road tractors weigh over 20000 full of fuel. But like I say neat looking just not ready for prime time.I suspect will be seeing Diesels for the near future as even cng power has had only limited success.
Their website is full of exagerations and incorrect facts and some pretty tall claims. The first unit doesn't appear to exist in reality yet. Most likely another green company headed for bankruptcy subsidized by we the people. But again I could see one with more normal modern diesel power becoming reality. A truly innovative concept but not ready for the real world.It would however be an interesting model.
A more conventional diesel version would be possible but hydrogen power will not likely catch on due to current infrastructure which would be cost prohibitive to change. Still requires oil products such as lubrication, plastic parts, tires etc. And the batteries present a host of issues as many Prius have owners found out. Looks wise not bad similar to other future designs I've seen.
Ok here are the facts as close as can remember. 96 to 02 volvo built the vnl 200 (4x2) vnl300 (6x4) vnl 610 midroof vnl 660 small condo vnl 770 big condo. In 03 they were redesigned with new hood etc daycabs kept same model numbers and sleepers are vnl 630 vnl 670 vnl 780. Also offered are a short hood version in day cab and sleeper models called the vnm most sold as daycabs with very few sleepers. Dart transits volvos are vnm's. The vhd has it's own hood with the basic Volvo daycab but is different underneath as it is a vocational chassis. The vnl430style single bunk is the only sleeper offered on the vhd. A better option to build a vhd might be starting with a resin daycab conversion for the 780 kit. Volvo also builds a special model for auto hauling the vah 300 430 and 630. The hood is similar to the vhd with a chopped top cab and low profile chassis.
