![]() I also noticed the shift pad on the wing dash, and with neutral selected, I fired up the engine and we were on our way. In its Mack persona, it has all new programming to match it to the Mack engines, which have far different power and torque curves.Īs I climbed into the truck, I noticed the absence of a gear lever and a clutch. But mDrive is by no means the same transmission. The mDrive has common mechanicals with the automated Volvo I-Shift, which is used in Volvo trucks in Europe and around the world, including here in America. And that’s why the mDrive has to be so different from the I-Shift of Volvo-branded trucks. It takes an intelligent transmission to account for that. A feature of this profile is EconoBoost, an on-demand torque boost when the full throttle is held for 3 seconds. Though the MP8 is basically the same engine as the Volvo 13-liter, the Mack has its own personality - in this case, the Econodyne profile, which has long been part of the Mack brand. It’s the 13-liter version of the overhead camshaft engines developed to meet 2010 emissions regulations. The Mack Pinnacle I drove featured the Mack MP8 at its highest rating: 505 hp with 1,760 lb.-ft. Further, Warmkessel said the combination of aero improvements and intelligent mDrive transmission with the new Selective Catalytic Reduction (Mack calls it ClearTech) emissions reducing technology could offer fuel savings greater than 12 percent over previous highway models. In fact, at the 2011 MATS, Mack Product Marketing Manager Jerry Warmkessel said the Pinnacle had been through the National Research Council wind tunnel in Ottawa, Ontario, and delivered a 6 percent gain in fuel savings. ![]() It’s Mack’s highway tractor with all the aero aids optimized. The Pinnacle was introduced in 2006 to coincide with the launch of the MP engines as the truck and engine combination that would meet the upcoming 2007 emissions regulations and, more importantly, carry through the Environmental Protection Agency’s 2010 emissions standards into the next decade. But the Vision was a complete redo of the earlier truck with more room for the driver, a total aero package and the “M” shape to the grille. In fact, it goes back to the launch of the Vision in 1999 and, in its basic cab structure, back to the launch of the Mack CH in 1988. ![]()
