HEAVY-DUTY LEADERSHIP.

2014 RAM HEAVY DUTY: OUTSTANDING

POWERTRAIN SELECTION, OUTPUT AND CAPABILITY.

THE LEGENDARY 5.7L HEMI



Aluminum cylinder heads combine with

hemispherical combustion chambers

for outstanding airﬂow leading to

indispensable power and torque.

Variable Valve Timing (VVT) improves

performance and also contributes to outstanding

torque output over a large rpm range.

Dual-ignition technology—two spark plugs

per cylinder—increases peak power and

torque, reduces exhaust emissions, helps

improve fuel efﬁciency and smoothes the idle.

10,000-mile oil change intervals help

keep costs-of-ownership in check.

Standard on Ram 2500/3500 SRW. The credentials of this extraordinary gas

powerplant rank as ideal examples of technical proficiency and the limits

of engineering, for the properties of the hemispherical engine head are

all about power. Since its introduction, the varied applications of the

hemispherical head have included WWII-era prototype aircraft (and even

some tank applications), and attained unprecedented dominance during

the distinctively American muscle car era. Today, with its refinement

reaching new levels of fuel efficiency and power, it’s the obvious choice as

standard engine for the 2014 Ram Heavy Duty pickups.

In Ram Heavy Duty models, this iteration of the 5.7L HEMI V8 delivers

every pound-foot of torque you need—with unexpected and perhaps

even surprising fuel-efficient performance. Combined advantages here

include VVT, outstanding transfer cases for 4x4 applications and the

ideal transmission: the 66RFE 6-speed automatic. All work together to

contribute to the HEMI V8 legacy: outstanding performance with fuel-

sipping operation.

+ The competitive fuel efﬁciency generated

by the 5.7L HEMI V8 accompanies

serious performance capability. For

single-rear-wheel models, the 5.7-liter

HEMI V8 delivers incredible standard

power and torque compared to other

V8 engines.

+ The incorporation of iDFSO (interactive

Deceleration Fuel Shut-Off) adds to the

fuel-efﬁcient performance of the 5.7L

HEMI V8. iDFSO turns off the ﬂow of fuel

during deceleration, with no noticeable

change in engine performance—a real-

world and bottom-line advantage to

this powerplant.

TRANSMISSIONS: e 5.7-liter HEMI V8 is mated to the

long-proven 66RFE 6-speed automatic, a component that

exceeds typical demands for anticipated towing and hauling.

e transmission features driver-adaptive shifting, three

multiple clutch packs and dual lters on a dual-stage pump; an

independent lubrication cooler on the 66RFE ensures ample

pressures under all driving and load conditions.

RAM TOUGH TRANSFER CASES

The two transfer cases utilized by the Ram Heavy Duty models

more than meet the need. The BorgWarner BW 44-46 transfer

case features responsive electronic shift-on-the-fly engineering,

with three operating ranges, plus Neutral.

The manually activated BW 44-47 transfer case features three

operating ranges, plus Neutral. Both of these impressive units

offer a low-range reduction ratio of 2.64:1—an ideal ratio when

off-road in a slow rock-climbing situation, or when using Ram

tough 4x4 capability on steep grades. It’s all about capability and

performance and, in both scenarios, Ram Heavy Duty pickups

are designed to excel.
