AUBURN HILLS, Mich., Jan. 5 /PRNewswire-FirstCall/ -- The 2005 Chrysler
300C and Dodge Magnum RT will be the first high-volume, modern production
vehicles in North America to feature fully-functioning cylinder deactivation
when they go on sale in the spring of 2004. The Multi-Displacement System
(MDS) will be standard equipment on the Chrysler 300C and Dodge Magnum RT.
"The Chrysler Group MDS seamlessly alternates between smooth, high fuel
economy four-cylinder mode when less power is needed, and V-8 mode when more
power from the 5.7L HEMI(R) engine is in demand," said Eric Ridenour,
Executive Vice President Product Development, Chrysler Group. "This optimizes
fuel economy when V-8 power is not needed, without sacrificing vehicle
performance -- 2005 Chrysler 300C and Dodge Magnum RT owners will get the
maximum benefit without any compromises."
Owners of the Chrysler 300C and Dodge Magnum RT will receive the powerful
benefit of the HEMI engine with the fuel economy that they would only expect
from a smaller, less powerful engine.
"The MDS was part of the engine's original design," said Bob Lee, Vice
President Powertrain Product Team, Chrysler Group. "This resulted in a
cylinder-deactivation system that is elegantly simple and completely
integrated into the engine design. The benefits are fewer parts, maximum
reliability and lower cost."
Some of the significant technologies enabling the Chrysler Group MDS are
the speed of electronic controls, the sophistication of the algorithms
controlling the systems and the use of Electronic Throttle Control. The HEMI
will be able to transition from eight cylinders to four in 40 milliseconds
(0.040 seconds).
The HEMI engine with MDS has completed over 6.5 million customer-
equivalent miles through Chrysler Group's development and durability testing.
It is covered by the 7-Year/70,000-mile Limited Powertrain warranty.
The system deactivates the valve lifters. This keeps the valves in four
cylinders closed, and there is no combustion. In addition to stopping
combustion, energy is not lost by pumping air through these cylinders.
Customers will experience estimated fuel economy gains of up to 20 percent
under various driving conditions, and a projected 10 percent aggregate
improvement. Improved fuel economy is realized without any change in customer
experience -- drivers will receive the benefit without changing their driving
habits and without compromising style, comfort or convenience.
