IT'S INNOVATIVE, INTUITIVE, REFINED AND RIGHT ON TIME: COMBINING 5.7 LITERS OF HEMI
V8
POWER WITH MDS — THE INTELLIGENT MULTI-DISPLACEMENT SYSTEM.
As a global manufacturer of some of the fi nest trucks and cars on the planet, we carry a certain
responsibility along with those impressive Ram payloads. Which is why our engineers
started working on ways to combat increasingly unpredictable fuel prices years ago.
One strategy was to re-engineer the long-trusted and heavily utilized 4.7-liter V8 into an
effi cient, Flex Fuel-compatible power plant. But to address the legendary power of the
5.7-liter HEMI V8, our engineers took a different turn, reaching a radical if not brilliant
solution: MDS, the fuel-saving Multi-Displacement System.* It's tomorrow's engineering
today. And it's in Dodge Ram.
Operating silently and seamlessly above 18 mph (and in all gears except reverse), MDS
transforms the powerful and durable HEMI V8 into a gas-sipping 4-cylinder* during many
daily driving situations — including while cruising at highway speeds, during low-throttle
coasting, and even while climbing low hills. Although the system deactivates four of the
eight cylinders — indeed, fuel injection to the inactive cylinders is shut off completely, and
all the appropriate intake and exhaust valves are completely closed — the engine's equal
fi ring intervals are still maintained.
The benefi ts of MDS are extensive. To learn more about MDS, visit dodge.com/ram/mds
