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.
