EASY SERVICING

The MP Engine Series features 35,000-mile service intervals for highway trucks and 450-hour or 15,000-mile oil drain intervals (whichever comes first) for vocational applications. These engines are designed with convenient access points that make servicing a snap.

SINGLE OVERHEAD CAM

This MP Engine Series uses a robustly designed single overhead camshaft that reduces stress and incorporates an ultra-high-pressure fuel injection system.

BUILT LIKE A MACK TRUCK®

The MP Engine Series is designed with fewer parts, including one-piece steel pistons and stronger bearings and cylinder heads, giving operators a true powerplant that's built to last.

SPLASH SHIELDS

Hood splash shields keep the engine compartment clean extending component life, and they lift with the hood to create more room for vehicle maintenance and service.

A BRAKE POWERFUL ENOUGH TO STOP A MACK

The Mack PowerLeash™ engine brake provides more braking horsepower through mid-RPM ranges, and weighs 50 pounds less than competitive engine brakes. It is fully integrated with the MP Engine Series, and with better braking over the entire speed range, PowerLeash delivers the most retarding horsepower ever in a Mack engine brake.

MAXIMUM PERFORMANCE

Offered in three engine families — Econodyne®, MaxiCruise® and Maxidyne® — the MP Engine Series is tailored to fit your applications. The Econodyne engines are ideal for typical interstate applications with extended times at engine cruise speed with part load/part throttle applications where fuel economy is a priority.

BOOST POWER AND FUEL EFFICIENCY

The Econodyne engines use an intelligent torque management strategy called EconoBoost to give drivers the extra muscle needed to keep vehicle speed constant under full engine loads to avoid downshifts. Initiating at 1,300 RPM with the driver maintaining speed for three seconds of full throttle (while in the top two gears), EconoBoost provides up to an additional 200 lb.-ft. of torque.

ELECTRONICS THAT BOOST PRODUCTIVITY

The fourth generation of the time-tested and road-proven Vehicle Management and Control System (V-MAC® IV) gives you greater control over your costs and lets you manage your truck and engine better than ever. This advanced system features more than 100 proven programmable features that include standard multi-level MPH sensor tamper detection and a host of other options.

GUIDING YOU TOWARD GREATER PROFITABILITY

Mounted high and centered in the dash for easy reading, the standard large-display Co-Pilot™ driver information system sets the industry standard. Drivers can easily toggle through information screens with a four-button steering-column stalk. This innovative display has over 50 screens that provide real-time fuel economy and trip data, detailed maintenance and fault summaries, and supplemental sensor readings.

VARIABLE GEOMETRY TURBOCHARGER

The electronically controlled Variable Geometry Turbocharger incorporates the latest technology to control turbo boost at all RPM ranges and engine loads. Mack provides additional cooling and lubricant for the turbo and actuator.

Auto Neutral

The transmission shifts to neutral if the engine is turned off while still in gear, or when the Parking Brake is applied. This is designed to prevent engine stalling and reduce the load on the drivetrain.

Grade Gripper

On a grade it holds the Service Brake until the throttle is applied.

Gear Selection Adjustment

Starting gear when stationary and driving gear while moving can be manually selected within limits by using the up/down buttons on the premium shift pad.

PowerLeash™ Engine Brake

The control logic of the PowerLeash engine brake will automatically downshift the mDRIVE transmission for maximum engine brake performance. Also, in Auto mode a target retarding MPH can be set (when not in cruise control) to maintain a desired downhill speed.

Easy Shift

Provides smooth, precise and less aggressive shifting. It is recommended for cattle haul, liquid bulk haul, and similar applications where load shifting must be minimized.

Cruise 'n Brake

The Mack Cruise 'n Brake function limits engine brake operation while in cruise control until a target speed has been reached.

Low Speed Modulation Control

Provides smooth low speed control without the need to continually brake and accelerate.

MackCellerator™GER

Allows the driver to raise the engine RPM while automatically shifting to a lower gear, affording higher RPM and increased HP to assist with a safe and quick pass all without taking the driver's hands off the steering wheel or eyes off the road.

DELIVERING HEAVY-DUTY SUPPORT

The Mack C150/151 Axle Carriers are an important component of the Mack integrated Pedigree™ Powertrains, performing optimally because they're designed and manufactured to work together with the engine, transmission, axles and electronics.

Designed for the highway

Mack trucks are also available with UniMax™ steer axles with unitized hubs specifically designed for highway applications. Our 12,000-lb. and 14,600-lb. capacity axles are now available for use in our Pinnacle and CH tractors.

DRIVER AXLES BUILT TO LAST

You want drive axles that last, require little maintenance and minimize unexpected downtime. The S40 Series fills all those needs. Its housing is made from fabricated steel to effortlessly handle heavy loads up to 44,000 lbs. — an ideal choice for highway applications.

CLOSE TO INDESTRUCTIBLE

The S46 is a premium drive axle made of cast ductile iron and carries loads rated to 46,000 lbs. This severe-duty workhorse saves weight by casting thicker reinforcing to only the parts that take the brunt of the load. The S46 is the strongest 46,000-lb. axle we've ever built.

MP7 Engine

MP8 Engine

MP10 Engine

ENGINE: MACK® MP7 OR MP8

The MP7 engine is powerful and lightweight to maximize payloads. This 11-liter engine has an amazing power-to-weight ratio with a horsepower range from 325 to 405 HP and torque ratings from 1,200 to 1,560 lb.-ft.

This lightweight engine is ideal for weight sensitive applications, helping you boost payload when used with our Granite® and Pinnacle™ models. The MP7 engine is also well suited for refuse applications and is outfitted in all TerraPro™ models.

ENGINE: MP8 Engine

The MP8 engine provides the muscle to shoulder heavy workloads. This 13-liter engine has a horsepower range from 415 to 505 HP and torque ratings from 1,460 to 1,860 lb.-ft. This engine achieves a maximum power density of up to 38.8 HP/liter. This allows the MP8 (505 HP) to weigh several hundred pounds less than a 15-liter engine at an equivalent horsepower.

The MP8 engine, available in Granite®, Pinnacle™ and select TerraPro™ models, provides plenty of confidence as it delivers extra brawn for heavy-duty vocational and highway applications.

ENGINE: MP10 Engine

The 605-horsepower, MP10 engine is the most powerful engine we've ever built. This 16-liter engine has a horsepower range from 515 to 605 HP and torque ratings from 1,860 to 2,060 lb.-ft. This engine delivers high horsepower while putting low stress on the engine with a power density of 37.8 HP/liter.

Built exclusively for the Titan by Mack, the MP10 engine boasts best-in-class torque ratings. And thanks to its impressive engine, Titan shines in logging, oil field, coal, heavy equipment, special-permit and severe, heavy-haul applications.
