Mack®MP™Engine
Series MP7 & MP8
Blowing away the competition.
The all-new MP7 and MP8 engines, the latest members of the
Mack®MP™Engine Series, draw on proven technology to boost
power and run cleaner. These engines meet the strict emissions
requirements of the EPA for 2007. Engineered with the power,
torque and durability you have come to expect from the industry’s
leader in integrated powertrains, the MP7 and MP8 engines are
versatile enough to cover all highway and vocational applications.
A powerful addition to the family.
The MP8 engine has the highest horsepower with the lowest
emissions ever offered by Mack. The 13-liter MP8 has a horsepower
range from 415 HP to 485 HP and torque levels from 1,540–1,700 lb.-ft.
The 11-liter MP7 engine possesses a horsepower range from 325 HP
to 405 HP and torque ratings from 1,200–1,560 lb.-ft.
Minor adjustments make a major
improvement.
The new MP7 and MP8 engines boast a few improvements from
their predecessor, the US’04-compliant MP7.The most significant is
the redesigned Exhaust Gas Recirculation (EGR) Cooler, which
now utilizes a tube-and-insert configuration for even more efficient
cooling. These engines deliver the same performance and reliability
of the previous MP7, which has been road-tested and respected by
drivers for more than two years.
Meeting the Mack standard.
Engineered to perform to legendary standards, these new MP engines
live up to the indisputable reputation of durability and dependability that
Mack has delivered on for more than a century. These state-of-the-art
engines feature single overhead cams and ultra-high-pressure
fuel injection. The electronically controlled Variable Geometry
Turbocharger incorporates the latest technology to cool both the turbo
and actuator. It is designed with fewer parts, has one-piece steel
pistons, and stronger bearings and cylinder heads, giving operators a
powerplant built to last.
Log more miles with less stops.
These new engines remain true to the MP Engine Series, which was
introduced with improvements to the injection and air management
system to achieve better fuel economy. Fuel economy is expected to
increase by approximately 3 percent for highway and 6 percent for
vocational use.
An engine brake powerful enough to stop a Mack.
Mack’s engine brake, PowerLeash,™is ideal for operation in the new
MP7 and MP8 engines. It is every bit as durable, powerful and reliable
as a Mack truck itself. It provides more braking horsepower through
mid-RPM ranges, and weighs less than other engine brakes.
Pound-for-pound, these engines deliver.
All the power you need, without an ounce of additional weight.
The 11-liter MP7 engine is a lightweight and compact package. It is
37 pounds lighter than previous Mack vocational engines and
153 pounds lighter than previous Mack highway engines.
Engineered for Ultra Low Sulfur Diesel (ULSD).
The all-new MP7 and MP8 engines have been designed, developed
and tested using ULSD, which uses only 15 ppm (parts per million)
sulfur. These engines will not meet the emission standards using
pre-2007, 500 ppm diesel fuel. The ULSD fuel must be used in all
US’07-compliant engines that use a catalyzed DPF or the catalyst
will be poisoned. Improper fueling will reduce its effectiveness for
regeneration and potentially require more frequent filter service or
replacement of the catalyst. Any emission control system component
damage due to improper fueling will not be covered under the Mack
engine warranty.
Ultimate performance.
The new MP7 and MP8 engines are designed to maximize the many
great benefits and features of each Mack truck.Each engine comes in
the same three families (Maxidyne,®MaxiCruise®and Econodyne®) to
optimize performance in a wider operating range. Maxidyne provides
power for high-performance, severe-duty conditions, especially in
off-road applications. MaxiCruise provides performance for rolling
interstate and on and on-off applications. Econodyne is ideal for
typical interstate and part load/part throttle applications where fuel
economy is the priority.
Seamless integration.
Each new MP7 and MP8 engine will match current transmission
offerings. The vocational-preferred Maxidyne engine family works
with the Mack T300, TM300, vendor manual and full-automatic
transmissions. The MaxiCruise engine family, which is ideal for
highway and vocational use, utilizes the Mack T300, vendor manual,
automated manual and full-automatic transmissions. And the
Econodyne engine family works best for highway applications using
the Mack T300, vendor manual and automated manual transmissions.
The path to profitability.
Mack electronics deliver the technology you need, so drivers and
managers can boost productivity. The new Granite®MP Engine Series
and Mack Pinnacle™MP Engine Series use our time-tested and
road-proven Vehicle Management and Control System or V-MAC®IV.
This next generation of advanced electronics gives you greater
control of your costs and lets you monitor your truck and engine
better than ever. In addition to hundreds of proven programmable
features, V-MAC IV adds a host of new items, from the simple
yet smart design of the daytime running light override, to the
comprehensive ABS-based tamper detection. V-MAC IV comes with
DataMax,™an advanced trip recorder that captures vehicle trip
histories, duty cycle information and scheduled maintenance intervals.
The ultimate watchdog.
The GuardDog™preventative maintenance monitor is one of the best
weapons you have to combat unplanned downtime. Maintenance data
comes from real-time sensors instead of preprogrammed schedules
based on mileage. As a result, accurate information reduces
downtime and boosts efficiencies based on your operation.
Top-notch protection.
The base warranty as provided is 3 years/300,000 miles on the MP7
and MP8 engines. Extended Bulldog Protection Plans®can be tailored
to meet your needs.
Clean livin’.
As one of the industry’s vertically integrated manufacturers that
designs and builds its own trucks and engines, we were able to
seamlessly incorporate Diesel Particulate Filters (DPF) into our
exhaust system, producing cleaner running trucks without sacrificing
any benefits of the MP Engine Platform. Mack has engineered a
technically savvy solution that is commercially viable for US’07.
Designed to fit your needs.
The DPF is designed in three unique configurations: Mack Back-ofCab Catalyzed and Non-Catalyzed DPFs, and a compact MackCap
™
Catalyzed DPF to fit the needs of each truck. In a catalyzed DPF, a
small amount of fuel is injected upstream in the exhaust. This fuel
does not combust. The regeneration is a chemical reaction between
the platinum-coated catalyst in the DPF and the fuel hydrocarbons
which raises the temperature within the filter high enough to oxidize
the soot collected in the filter. In a non-catalyzed DPF, a thermal
regenerator is used to elevate the temperature within the filter to
oxidize the soot. Active regeneration only takes place when the engine
is creating sufficient passive heat. The DPF reduces particulate
matter (PM) emissions by more than 90 percent from US’04 levels.
Maintenance is a breeze.
Each DPF cleans itself through regeneration. The DPF does require
service cleaning at a minimum of 150,000-mile intervals for highway
applications or approximately 4,500 hours for vocational applications.
During service, the filter is removed, cleaned and reinstalled.The DPF
is designed to last the life of the engine.
