Fuel Choices

A key factor for transportation professionals when making school bus acquisition decisions will be what fuel options to choose. Hoekstra Transportation’s goal is to be a resource in the decision making process and help operators make informed decisions that will help reduce emissions and lower operating costs.

Clean Diesel

The black cloud behind a school bus is a thing of the past. Today’s diesel offers the highest fuel efficiency and the smallest “net” carbon footprint – better than other non-EV options offered. Clean diesel is the most cost-effective option because it has the best fuel efficiency. Because it has the best fuel efficiency, it has the longest operating range, the best resale value, and emits less tailpipe pollutants than other fossil fuel burning school buses. In addition, the new DD5 diesel engine, found in the Saf-T-Liner C2 school bus, comes equipped with industry-leading real-time diagnostic systems. It is no wonder most school districts across the United States and Canada choose new diesel for their fleets.
