The MP10 is being offered in the new Titan by Mack, a top-of-the-line heavy construction and transport truck and tractor available later this year. The MP10 engine and the Titan model were first introduced to vocational customers on March 12 in Las Vegas at the ConExpo/Con-Agg 2008 Exposition.
Mack has a long tradition of equipping trucks with big-block engines, going back decades to the RW Super-Liner with its E9-500 power plant. The modern MP10 engine adds the intelligent power management field-proven by its siblings, the 11-liter MP7 and 13-liter MP8 engines. Like the MP7 and MP8, the MP10 is certified to meet the US'07 emissions standards, using ultra-low sulfur diesel fuel and a diesel particulate filter. All of Mack's MP engines come with the next generation of Mack's proven Vehicle Management and Control System, V-MAC IV.
"The MP10 offers a perfect balance of low-end power and high-speed horsepower that's ideal for heavy transport applications," said David McKenna, Mack powertrain sales and marketing manager. "It has a 'hump' horsepower curve, which means it has more power at 1,500 rpm than it does at 1,850 rpm. This encourages drivers to operate at lower rpm with greater power for greater fuel efficiency."
This single overhead cam engine can generate peak horsepower of 515 horsepower, 565 horsepower and 605 horsepower in its MaxiCruise configuration. Maximum torque ranges from 1,860 pounds-feet through 2,060 pounds-feet at 1,200 rpm. (A Maxidyne configuration will be released later.) This massive torque gives the MP10 the ability to pull heavy loads from a dead stop and the power to get them up to speed on the highway.
With approximately 38 horsepower per liter, the engine hits the sweet spot of being sized correctly for brute power while still being optimized for fuel efficiency, McKenna said. The MP10 is also a very quiet engine, with a harmonically balanced camshaft and insulated engine mounts to reduce noise, vibration and harshness.
