COLUMBUS, IN - In a dramatic demonstration of technological agility, Cummins finished off a press conference here yesterday by unveiling its all-electric, zero-emissions class-7 tractor. Obviously, it's a first for the 98-year-old diesel manufacturer that wants to become known as a powertrain provider, not an engine builder. It was a surprise to many, even to those of us who knew electric power was in the cards at Cummins, as well as being a small slap in the face to Tesla, which has been threatening to introduce an electric tractor next month.
Called the 'AEOS' electric commercial vehicle demonstrator, and built by Roush on what seems to be an International ProStar base, it's a working 4x2 regional hauler, not just a concept shell. Cummins sees its role in vocational applications like urban delivery, port drayage, and terminal container handling.
It's claimed to achieve over 30 miles per gallon in diesel-equivalent terms while accelerating 25-35% faster than the same tractor powered by an 11- or 12-liter diesel (depending on rear-axle ratios, of course).
