In line with its commitment to maximizing customer value, Mack Trucks has introduced two new offerings that build upon the company’s longstanding leadership in integrated products: the
Mack Super Econodyne powertrain and Mack Pedigree Uptime Protection service and support package.
Integrated powertrains have been at the heart of Mack since its inception in 1900. Today, every truck with a Mack Pedigree Powertrain – proprietary engine, transmission and axles – features a gold Bulldog on the hood.
The new Mack Super Econodyne capitalizes upon the company’s legendary Pedigree Powertrain expertise to provide customers with a 3.5 percent improvement in fuel economy.
The new Mack Pedigree Uptime Protection is an integrated package of aftermarket solutions ensuring customer satisfaction throughout the service, parts purchasing and asset protection experience.
“Mack recognized more than 112 years ago that components designed to work together provide superior performance,” said John Walsh, Mack vice president, marketing. “The new Super Econodyne powertrain package is a perfect example of what we can accomplish with a Mack Pedigree Powertrain.
“With Pedigree Uptime Protection, we’re extending the concept of integration beyond the product – integrating the entire truck ownership experience to deliver a total business solution that keeps our customers out in front of their competition.”
The Super Econodyne powertrain system is designed with all-Mack proprietary components for a complete Mack Pedigree Powertrain. The Mack MP8-445SE engine, Mack mDRIVE automated manual transmission, Mack C125 proprietary drive axles and Mack’s custom software all combine to offer “a system designed for industry-leading fuel efficiency without compromising power or performance,” said Walsh. “The result is up to 3.5 percent better fuel efficiency compared to other similarly spec’d vehicles.”
Ideal for dry van, refrigerated, liquid and dry bulk haul, and flatbed operations, Super Econodyne is available on all Mack Pinnacle models, a Class 8 commercial vehicle known as a fuel-efficiency leader among on-highway trucks.
With the addition of Super Econodyne, rated up to 88,000 lbs. GCWR, the aerodynamic Pinnacle offers even greater operating benefits while maintaining driver satisfaction, he noted.
Contributing to the fuel-efficiency improvement is the Super Econodyne’s “down speed” feature, which is engineered to “down speed” more than 200 rpm at a highway speed of 65 mph, cruising at 1160 rpm versus 1380 rpm.
This reduces fuel consumption by up to 2 percent compared with previous engine models, with a corresponding reduction in CO2 emissions, said Walsh. “The Mack proprietary C125 drive axles deliver an additional 1.5 percent fuel economy improvement.”
“Super Econodyne builds upon our roots,” said David McKenna, Mack director of powertrain sales. “Mack pioneered the low-speed Econodyne engines in the 1960s.
“Historically, we’ve insisted on gearing fast, running slow. Now, we’ve designed a completely integrated system to run efficiently at 450 rpm above idle speed when before it was 700 to 800 rpm above idle speed.”
The Mack MP8-445SE offers 445 hp and up to 1,760 lb-ft of torque. The C125 axles have a 2.66:1 ratio. All powertrain components communicate with each other via Mack software.
“It’s the ultimate in complete powertrain integration,” McKenna said. “The engine seamlessly communicates with the transmission, which seamlessly communicates with the vehicle, resulting in instantaneous decisions. Add the Mack C125 drive axle, and we’re talking about fuel-efficiency benefits never before realized in a powertrain system.”
Key to the fuel efficiency delivered with the Super Econodyne powertrain package is the Mack mDRIVE transmission. The 12-speed automated manual has no clutch pedal, and the gearshift is operated by an intelligent shift pad module and managed by sophisticated electronics.
