Given the work the engineering teams at truck manufacturers are doing to continue to push the fuel economy and durability envelopes, it is better to look at a spec review as a chance to make what is already good even better.<\/span><\/p>\n

I\u2019ve been seeing announcements from truck makers about certain models of their vehicles that are now being spec\u2019d for maximum fuel efficiency. These models not only have fuel efficient engines, but also tend to be spec\u2019d with automated manual transmissions and a variety of aerodynamic devices.<\/span><\/p>\n

The OEMs seem to be constantly modifying standard components on trucks versus optional components with a goal of making trucks more fuel efficient while also lowering the total cost of ownership.<\/span><\/p>\n

Of course, no two fleets have the exact same needs, and there is no one-size-fits-all truck spec that will work for every fleet. But given the fact that truck makers are continually tweaking vehicle specs, it makes sense for fleets to review specs every time they order new vehicles. I know it can be tempting\u2014especially if fuel economy numbers seem to be good\u2014to just order new trucks spec\u2019d with the same spec as the last order. It is the \u201cif it ain\u2019t broke don’t fix it\u201d adage.<\/span><\/p>\n

But given the work the engineering teams at truck manufacturers are doing to continue to push the fuel economy and durability envelopes, I think it is better to look at a spec review as a chance to make what is already good even better.<\/span><\/p>\n

I also know that some standard specs still have a delete option on them that allows a fleet to remove a component from the spec\u2014sometimes with a delete credit. I suggest that before deleting an item that is part of the standard spec, the fleet manager talks with the OEM to make sure they understand all the implications of deleting a standard part of a model\u2019s spec. Working hand-in-hand with their OEM partners, fleets can get trucks that will achieve the best MPG for their duty cycles while being durable and reliable.<\/span><\/p>\n

Maybe I am a bit biased given that I am an engineer, but I think the OEMs have some very smart folks working for them who are focusing on optimizing some models for fuel efficiency. The specs they develop look at the truck as a complete system that is fine-tuned to work together for optimal results.<\/span><\/p>\n

Go ahead, ask all the questions you want about a vehicle\u2019s spec, but know that it is also okay to trust an engineer. They really do want to design the best trucks possible, and most of us are really nice, friendly people who will be happy to explain why we did what we did, but you might need to block out a lot of time.<\/span><\/p>\n
