1 Thomas Built Buses Saf-T-Liner C2 Propane marks the return of Powertrain Integration to the propane autogas Class C bus marketplace. Returning the legendary big block to its key role in pupil transportation has been a goal since Powertrain Integration (PI) and CleanFUEL USA (CFUSA) learned GM was sunsetting the 8.1L engine. PI, CFUSA, and Allison formed a combination that transforms the industry s finest Class C bus into the finest propane autogas bus. Following over four years of painstaking development and rigorous testing to OEM standards, the wait is over...

12 PIthon 8.0L LPI Operational Benefits Fuel cost savings of propane autogas Clean burning = less maintenance Vehicle weight approximately 500 lbs lighter than diesel Passive emission controls no DEF, exhaust regens, or DPF service required Exceptional cold weather starting Fast warm-up with abundant cab and passenger compartment heat Mature technology; uses SAE tools Superior driver experience: smooth and quiet with responsive power

13 PIthon 8.0L LPI Health & Safety Benefits With PIthon, gas and particulate emissions are greatly reduced, especially compared to diesel. Both elements of engine exhaust aggravate respiratory problems such as asthma and constitute a health risk to children waiting on idling buses. PIthon delivers the potential to keep kids safer. Reduced engine noise levels mean kids can use their inside voices and drivers can better focus on the road.
