Showcasing its industry leadership in fuel efficiency and powertrain integration, Mack Trucks recently launched a North American tour featuring the Mack Super Econodyne powertrain package. Super Econodyne-equipped Mack Pinnacle models are currently traveling between Mack dealers throughout the U.S. and Canada, giving customers an opportunity to experience the fuel economy and performance benefits of the recently introduced integrated powertrain package.
Super Econodyne efficiently and effectively integrates the Mack MP8-445SE engine, mDRIVE automated manual transmission and C125 axles, exemplifying the benefits of a Mack Pedigree Powertrain. With Super Econodyne, customers realize up to a 3.5 percent improvement in fuel efficiency compared to other similarly spec’d vehicles – with equivalent or better power and performance.
“This tour is a dynamic way for customers to experience first-hand the benefits of a Mack integrated powertrain solution,” said John Walsh, Mack Trucks vice president of marketing. “Like all Mack Pedigree powertrains – Mack engine, Mack transmission, Mack axles – Super Econodyne capitalizes on the seamless communication that comes with the front-to-back use of proprietary components. The result is a powerful, performance-driven ride that enhances customer profitability, as well as driver satisfaction.”
Available in all Mack Pinnacles, Super Econodyne is engineered to “down speed” more than 200 rpm at a highway speed of 65 mph, cruising at 1160 rpm vs. 1380 rpm. This reduces fuel consumption by 2 percent compared with previous engine models – with a corresponding reduction in CO2 emissions. An additional 1.5 percent improvement in fuel economy is delivered through the Mack C125 drive axles.
Critical to the fuel economy delivered by Super Econodyne, Mack says, is the mDRIVE automated manual transmission. The 12-speed automated manual transmission has no clutch pedal, and the gearshift is operated by an intelligent shift pad module and managed by sophisticated electronics. Changes in grade, speed, acceleration, throttle position, torque demand and combined vehicle weight are constantly monitored by the mDRIVE, which also features two-speed reverse functionality to better control both road speed and engine speed.
The Super Econodyne tour will be in Texas and Louisiana through mid-November and will then continue to the Southwest and Central U.S. and eventually to Canada in spring 2013.
