DATTCO Sales & Service Offers Gasoline-Powered School Buses

DATTCO Sales & Service, one of New England’s leading bus dealers, recently worked with school districts in Maine to replace several diesel-powered school buses with gasoline engine buses, one of the latest alternative fuel school buses to hit the market. In Maine, where districts frequently battle very cold temperatures, the switch was a no-brainer, as gasoline engines startup much easier in cold temps and don’t require plug-in.

If you’re in the market for alternative fuel buses DATTCO Sales & Service’s expert sales team is here to help! We know alternative fuels – from gasoline and propane to electric – and we can customize and order vehicles to suit any need. Our promise – all vehicles purchased through DATTCO Sales & Service come with a partnership. We’re here for you after your bus has left our lot; providing warranty services, maintenance plans, parts, and more! Take a look at our inventory; if you don’t see what you’re looking for contact our vehicle sales office 800-229-4878, ext. 5757.



The CE Series with the PSI 8.8L gasoline engine is purpose-built and designed for stop and start operation, featuring similar power and performance to diesel, which allows for immediate acceleration after stops and greater hill-climbing capacity.

PSI 8.8L Engine Purpose-Built for the School Bus Industry
The PSI engine is exclusive to IC Bus and is based on the original GM 8.1L gasoline engine used in pickups and commercial vehicles. However, the two engines are not the same. IC Bus and PSI worked together to identify what works best in a school bus application and made several robust improvements to create an 8.8L on-highway, purpose-built engine for the school bus industry, including but not limited to:

  • Cylinder Heads: The modernized, heavy-duty, high-flow heads create fast burn to improve efficiency and reduce emissions.
  • Crankshaft: Forged and induction hardened steel crankshaft creates a durable block, capable of 1,000 ft-lb of torque.
  • Intake Manifold: A tuned 24-inch long-runner provides higher torque, while a special air-gap design keeps the engine air cooler to improve efficiency.
  • Camshafts: Optimized camshafts for low-speed engine operation to ensure customer expectations are met.

Commercial Grade Powertrain with Low-engine Speed Design
Based on customer feedback, IC Bus wanted to develop a gasoline-powered, commercial-grade V8 engine that features similar power and performance compared to diesel. The PSI 8.8L low engine-speed design produces less noise, heat, and wear than the competition’s gasoline engine. With this low-speed design, the CE Series Gasoline bus is designed to drive like a diesel with no compromise on engine power and reliability, resulting in diesel-like torque and performance, which simplifies the driver experience when transitioning to an alternative fuel.

IC Bus uses the industry’s preferred Allison commercial grade transmission across all powertrains for ease of maintenance. The shorter, sturdier shaft has increased durability, and over 44 percent more clutch material compared to Ford, so it holds gear and lasts longer in the toughest operation.

One-Stop Warranty with North America’s Most Powerful Dealer Network
When it comes to servicing your gasoline-powered CE Series, you can count on the broadest, most capable dealer network in the industry, no matter what component needs attention. IC Bus handles all warranty claims directly, and with the PSI 8.8L engine, we offer the industry’s only one-stop warranty:

5-year unlimited mileage warranty on engine
5-year unlimited mileage with no cost cap on engine towing
7-year unlimited mileage Allison Transmission warranty

In the end, the IC Bus CE Series powered by gasoline is purpose-built for the school bus industry, designed to deliver diesel-like performance with a low-engine speed design. See five reasons why the psi 8.8l is the best in its class.
