Cummins MidRange Engines Help You Gear Up for Success

When you’re helping a small-business owner, there’s no detail too small, including how to spec their delivery trucks for maximum productivity. The key to achieving the optimal combination of fuel economy and performance in a work truck is choosing the right engine, horsepower rating, transmission and the proper drive axle ratio. These details can add up to a big difference on your customers’ bottom line because they impact fuel economy, productivity and driver satisfaction.

If your customer is buying a new Class 4 or Class 5 truck and is weighing the choice between a gasoline or diesel engine, the general rule of thumb is that a diesel engine will deliver a lower total cost of operation in vehicles averaging 30,000 miles or more each year. Virtually all owners of Class 6 and Class 7 trucks will be spec’ing diesels because of the higher load factors and applications.

The most popular diesel engines in work trucks today are the Cummins 2017 B6.7™ and L9,™ which power a wide range of applications, from delivery vans and pickup-and-delivery trucks to vocational and municipality vehicles. These engines have been proven over decades of use with reliability that is first-in-class, drivability that keeps productivity high and fuel economy that keeps operating costs low.

The first step to getting the ideal engine spec is determining which kinds of routes your customer’s truck will be running and the weight of the load to be carried. A florist operating a pickup-and-delivery truck in a city or the suburbs will have a very different duty cycle than a beverage distribution truck carrying a heavy load. The more work the customer is asking the engine to do, the higher the horsepower and torque that they will need.

The second step is coupling the engine with the right transmission and the optimal axle ratio.

A high rear axle ratio provides maximum towing and payloads, and may be needed for hilly terrain with steep grades. Additionally, a higher rear axle ratio will provide easier startability –  which is a good indicator for acceleration or off-the-line vehicle speed. For customers in frequent stop-and-go duty cycles who need to merge with traffic, a higher rear axle ratio will provide better productivity. The mid-range rear axle ratios deliver flexibility for operating on varied terrain with moderate loads, while lower or faster ratios are the best choice when running a flat terrain, with lighter loads or running at consistent highway speeds.

Cummins PowerSpec gives you a simple way to enter your customers’ operating parameters into a spec’ing tool in order to help get the right spec. You can help your customers determine whether they want to spec the vehicle for optimal fuel economy, maximum performance or somewhere in the middle. This decision will determine the overall drivability of the vehicle, which makes a big difference in driver satisfaction. Cummins PowerSpec also uses your input to provide optimized vehicle gearing, recommended electronic features and other settings – everything you need to help your customers achieve their operational goals.

If you or your customer need further assistance, your local Cummins distributor can provide complete technical support for the gearing process, or you can contact Cummins Care experts at 1-800-CUMMINS™ (1-800-286-6467).
