HIGH POINT, N.C. – (October 29, 2018) – Just two months after orders officially opened for the revolutionary Detroit™ DD5™ and DD8™ engines, Thomas Built Buses has sold out of its 2018 allocation of the DD5 engine.

“We knew these engines would be popular, but the market demand has far exceeded our expectations. We are blown away with how quickly we sold out of our 2018 allocation of the DD5 engine.  We never expected to open up orders for 2019 so soon,” said Caley Edgerly, president and CEO of Thomas Built Buses. “Both the DD5 and DD8 engines will be the most efficient, powerful, reliable and clean diesel school bus engines in the market and our customers cannot wait to add them to their fleets.” 

• The DD5 engine is a 5.1L engine adapted specifically for the Thomas Built Buses Saf-T-Liner® C2.  School districts can expect at least a three percent improvement in fuel economy compared to other diesel engines in the category, superior aftertreatment system performance and some of the longest service intervals in its class. 

• The DD5 was designed to produce fewer emissions, so it meets 2017 greenhouse gas (GHG17) standards and will continue to meet emissions standards through 2020.

• The DD5 engine also comes equipped with Detroit™ Connect Virtual Technician℠ remote diagnostic service. 

Customers can still order the DD5 for 2019 delivery by contacting their local Thomas Built dealer.
