During the past decade, Penn Detroit Diesel Allison has evolved into a company that provides a vast array of world class products and services to an expanded base of customers. As a result of this evolution, we have changed the name of our company to Penn Power Group which better defines our company’s focus and the services we provide.

Our rich history began over fifty years ago with Engines Incorporated which began our relationship with Detroit Diesel and Allison Transmission products in the eastern Pennsylvania region. In 1977, Engines Inc. was sold and renamed Penske Detroit Diesel Allison and in 1983, a management buyout took place and the company was renamed Penn Detroit Diesel Allison.

As the evolution of the business continued and expanded to include Carrier Transicold, MTU, GE Jenbacher and other industry recognized commercial vehicle products; we have announced the changing of our name to Penn Power Group to better reflect on the products and solutions we provide our customers today.

Penn Power Group is proud to be affiliated with some of the world’s largest manufacturer’s and providers of clean and efficient diesel and multi-gas engines, transmissions, transport refrigeration products, hybrid products and power generating equipment. As our customers transition through technology advancements within our industries, they can be assured that Penn Power Group continues to evolve and provide superior solutions.
