 Better MPG. Every Bus.
Indisputable evidence. That’s what Cummins has – proving that our ISB gets significantly better mpg than the MaxxForce 7 and the MaxxForce DT engines.
How much better? On a closed track simulating a rural school bus route, the ISB delivered 7.6% better fuel economy than the MaxxForce DT.
On a closed-track simulation of an urban school bus route, the ISB got 17.2% better mpg than the MaxxForce 7. The difference was even greater on an interstate route simulating travel to an activity outside the school district - 18.8% better mpg.
Testing was conducted with an independent third party and Cummins in-house engineers, using SAE Type III methodology with like horsepower and torque for the competing engines, on vehicles with comparable specs and loads.
What are the financial ramifications? Based on these results, each ISB-powered school bus in a typical urban fleet running 15,000 miles (24,140 km) per year will use 433 gallons less fuel and will cost the district $1,300 less to run than a bus equipped with a MaxxForce 7. This is assuming 15,000 miles driven annually and a fuel cost of $3 per gallon.
The bottom line is this: Across all types of vehicles, routes and loads, the ISB consistently gives bus fleets the best fuel economy of any engine in its class.
