EnGinEERinG. The most recent iteration of the legendary

5.7-liter HeMI

V8 for Ram Heavy Duty pickups now

features Variable Valve Timing (VVT), for outstanding fuel

management and performance across the board.

Additional features that make the HeMI V8 the ideal

choice when only a gas engine will do the job:

MORE pOWER. new cylinder heads on the redesigned

HeMI V8 now feature high-flow ports, larger valves and

increased compression ratio; results are measured

directly in performance — with no compromise in fuel

use. It's all about the engineering: The characteristic

hemispherical cylinder heads are what give the legendary

5.7-liter HeMI V8 such clout in the world of trucks — and

now this world-famous engine is better than ever.

No deductible. See dealer for a copy of Limited Warranty details. Non-Transferable. Not available on SRT,

Sprinter, Ram Chassis Cab, Hybrid System components (including transmission), and certain fleet vehicles.

1 6-spEED AutOMAtic. For Ram 2500 and 3500 Heavy

Duty pickups with available Cummins

6.7-liter Turbo Diesel.

Here's quality measured in durability. The 6-speed with

electronic Range Select works in concert with the factory-

installed engine exhaust brake, giving outstanding driver

control of rpm and speed — a valuable advantage when

decelerating downhill.

2 6-spEED MAnuAl. This heavy-duty transmission is

standard on all Ram Heavy Duty pickups equipped with the

6.7-liter Cummins Turbo Diesel. The ultralow first gear ratio

— as low as 6.29:1 — is ideal for heavier hauling.

3 5-spEED 545RfE AutOMAtic. Standard on 2500

pickups with the 5.7-liter HeMI V8. A specialized fifth

gear — available as an additional overdrive ratio — helps

provide increased fuel economy and reduced engine

noise at highway speeds. (The fifth gear ratio is 0.67:1 —

a 16 percent reduction in engine rpm relative to the

fourth gear 0.75:1 ratio.)

MORE tORquE. new for the 5.7-liter HeMI V8 is Variable

Valve Timing (VVT), a technology so sophisticated in the

field, it's utilized on Formula One race cars. VVT offers

increased engine breathing throughout the rpm range by

varying the degree that valves open and close in

conjunction with piston position. The advantages are

seen across the board: better performance, more efficient

operation, and measurable increased torque for towing

and hauling demands.

MORE EfficiEncy. The new short runner valve (SRV) active

intake manifold: Here, air intake flow is more efficiently

controlled by changing port length based on engine rpm.

At low speeds, the manifold uses a longer port path for

abundant low-end torque; at higher speeds, the manifold

uses a short port; air moves faster to the combustion

chamber. The SRV manifold contributes to more power and

torque — again, without sacrificing fuel economy.
