Surprise! Cummins goes electric

by Rolf Lockwood

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).

Printed to Go: 3D printing will transform your access to truck parts

by John G Smith

Distribution centers and jobbers couldn't possibly afford to stock every single part that a truck owner might need at a given point in time. The massive inventory would tie up far too much space and capital. The best they can do is play a numbers game, focusing on parts used in the widest volume of vehicles, and trying to limit investments in the components that are likely to gather dust on a storage rack.

Headlights Again: Now digital

by Rolf Lockwood

A few months ago I wrote a couple of times about headlights, complaining that the standard lamps offered in most vehicles -- from cars to heavy trucks -- are insufficient. Meaning, it's too easy to over-drive your lights at what are pretty ordinary speeds nowadays. The light just isn't thrown far enough down the road, reducing the ability of a driver to see far enough ahead to avoid an obstruction and maybe a catastrophic accident.
