Power of Choice

Why engine choice matters and how IC Bus delivers.

The Power of Choice makes all the difference.

Part of providing the best possible experience for customers and their drivers is providing just the right engines to meet the needs of the fleet. From Diesel and Gasoline, to high-performance Propane IC Bus works with reputable partners like Cummins® and PSI® in order to build the most resilient, reliable buses in the industry. Then we work with you to evaluate your evolving needs and help you select the right engines to meet your goals. With best-in-class Allison transmissions standard on every model, and best-in-class engine access on our flagship CE Series bus, we bring power and people together to keep you headed down the road.
 

The Choice is yours, but we help you get it right.

If rolling terrain with high mileage is part of your profile, diesel engines may be your best choice. If you’re running a small operation with a minimal footprint, gasoline may make the most sense. And for cold weather operations and environmentally conscious operators, propane or gasoline may be the appropriate path. Regardless of your preferences and your fleet’s demands, IC Bus has the expertise, and the engines, to meet your needs today and over time.
