Mack Trucks Inc. showcased its new Mack Pedigree (signifying all-Mack (componentry) Super Econodyne integrated powertrain at the2012 Mid-America Trucking Show.
The new Super Econodyne powertrain uses only Mack parts which include a MP8-445SE engine, mDrive automated manual transmission, C125 proprietary drive axles and custom software. The new powertrain offers 3.5% better fuel efficiency compared to other vehicles in the segment. The Mack MP8-445SE produces 445 hp. and up to 1,760 lbs.-ft. of torque. The C125 axles have a 2.66:1 ratio. All powertrain components communicate with each other via Mack software.
John Walsh, Mack vice president, marketing said: “Mack recognized more than 112 years ago that components designed to work together provide superior performance. The new Super Econodyne powertrain package we’re rolling out here 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.”
Aimed at dry van, reefer, liquid and dry bulk hauling and flatbed operations, the Super Econodyne is available on all Mack Pinnacle Class 8 models. Rated up to 88,000 lbs. GCWR, the new Super Econodyne integrated powertrain is aimed at dry van, reefer, liquid and dry bulk hauling and flatbed operations.
David McKenna, Mack director of powertrain sales said: “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.”
Moreover the new integrated powertrain is also fitted with a “down speed” feature., that was designed to “down speed” more than 200 rpm at a highway speed of 65 mph, cruising at 1160 rpm vs. 1380 rpm. Thanks this innovative feature the fuel efficiency is improved with 2% compared with the conventional engines.
The engine is mated on a “clutchless” 12-speed automated manual transmission which comes with a shift pad module to change the gears.
