Navistar Offers Industry's Most Comprehensive Lineup of Fully
Integrated Proprietary Powertrain/Vehicle Combination
International ProStar®+
with MaxxForce® 15 Provides
Heavy-Haul Customers with Powerful, Durable Powertrain without the
Hassle of Liquid Urea
LOUISVILLE, Ky.--(BUSINESS WIRE)--
At a press event at this week's Mid-America Trucking Show in Louisville,
Ky., Navistar, Inc. announced the production availability of its much
anticipated MaxxForce® 15, which completes the broadest, most
comprehensive lineup of integrated truck-engine offerings available to
North American commercial truck customers.
"With the addition of our MaxxForce 15, our lineup of MaxxForce Advanced
EGR big bore engines truly differentiates us from the competition," said
Jim Hebe, Navistar's senior vice president, North American sales
operations. "The introduction of the ProStar®+ with MaxxForce
15 now gives customers the ultimate combination in durability and power."
MaxxForce 15: Maximum Power and Durability for Most Demanding
Customer Needs
Engineered specifically for International's Class 8 heavy-duty
on-highway trucks, MaxxForce15 for the International
ProStar+ is available with up to 500 horsepower and 1,850 lb.-ft. of
torque and is the most powerful engine Navistar builds (International
PayStar heavy-duty vocational trucks are available with MaxxForce 15 up
to 550 horsepower). The engine is designed to handle the most extreme
demands that customers require.
The MaxxForce 15 is built on a proven block and crankshaft combined with
the fuel and air systems of the MaxxForce Advanced EGR system. This
combination delivers unprecedented hauling power and unrivaled
durability with the convenience of a hassle-free 2010 emissions
solution. Peak torque is achieved at 1,000 rpm and holds steady to 1,600
rpm, which reduces gear-shifting needs uphill and allows for shifting at
lower speeds when accelerating. Durability is enhanced with a four-bolt
connecting rod design. The four-bolt design assures the clamping force
and rigidity required for extreme loads and terrain, for which the
MaxxForce 15 is designed.
A premium cam and rolling element valvetrain system reduces friction and
operational load to maintain peak efficiency across the power band.
Interstage cooling between the turbos increases air density to maintain
peak power as speeds increase.
Comprehensive Line-up of Big Bore Power to Meet Wide Range of
On-Highway Applications
Beyond the addition of the MaxxForce 15 to Navistar's portfolio of
proprietary, integrated powertrains, the MaxxForce 11 and MaxxForce 13
continue to provide customers with a winning combination of lightweight,
fluid efficient power. With a combination of technologically advanced
materials and components, the MaxxForce 11 and MaxxForce 13 engines are
the ideal powertrain for a wide range of on-highway applications. They
deliver outstanding fuel economy, excellent power characteristics, an
exceptionally smooth and quiet ride, and high strength without added
weight.
Built on a block of compacted graphite iron (CGI), MaxxForce 11 and 13
engines provide superior strength, less fatigue and years of reliable
service up to 1.2 million mile B50 durability. The engine design
provides up to 500 pounds of weight savings over traditional big-bore,
gray-iron engines which translates to greater payload capacity.
A high-pressure common-rail fuel system, dual sequential turbo chargers,
effective heat-management system and low-friction design deliver more
torque and responsiveness at low rpm for outstanding fuel efficiency.
Peak torque is achieved at 1,000 rpm and holds steady to 1,200 rpm, a
much lower engine speed than other big bore engines. This reduces
gear-shifting needs uphill and allows for shifting at lower speeds when
accelerating.
MaxxForce 11 and 13 offer significant versatility, with available
options including the MaxxForce® Engine Brake by Jacobs as
well as programmable electronic parameters for increased fuel economy
and fleet maintenance. Later this year, MaxxForce 13 will be offered
with up to 500 horsepower and available for order in the International®
LoneStar®.
MaxxForce Advanced EGR: The Only No-Hassle Solution

market are powered by MaxxForce engines with MaxxForce Advanced EGR
emissions technology. Navistar has pursued its in-cylinder emissions
solution path for the past decade to provide the most customer-friendly
powertrain on the market. With MaxxForce Advanced EGR, customers won't
have the worry or inconvenience of finding and filling liquid urea.
MaxxForce Advanced EGR provides customers with a no-hassle solution that
keeps responsibility for emissions compliance with the manufacturer—not
the vehicle owner or driver.
