6.1-LITER SRT HEMI V8: Its 69.8 horsepower-

per-liter rating exceeds that of any vehicle ever

offered by Chrysler. It puts out 425 horsepower

and 420 lb-ft of torque thanks to bored-out

cylinders, high-ﬂow heads, SRT speciﬁc intake

and exhaust manifolds and beefed-up valves

that respond to a performance-minded camshaft.

It’s only ﬁtting that the reinforced block under

the hood of Challenger SRT8

is clad in Hemi

Orange from the original paint code.

5.7-LITER VVT HEMI V8 WITH MDS (AUTO

TRANSMISSION): Its aluminum cylinder heads

are milled with hemispherical combustion

chambers that beneﬁt airﬂow and, subsequently,

horsepower and torque. The new and improved

5.7-liter VVT HEMI features Variable Valve

Timing (VVT) for improved torque over an

extended rpm powerband. When equipped with

MDS, the computer-controlled variables all add

up to improved mileage.

HEMISTRY

Some might say that engines like the 5.7-liter VVT HEMI

V8 and

6.1-liter HEMI SRT

V8 – power plants that put out more horsepower

and torque than any Dodge passenger car since the fabled 426 Hemi

engines of the 1960s and 1970s – have already set their legend in

stone. Chrysler engineers would disagree. They took the brilliantly

powerful and masterfully efﬁcient 5.7-liter with Multi-Displacement System (MDS)

[1]

and

outﬁtted it with Variable Valve Timing (VVT) while cranking the compression up to 10.5:1. It

began as code name Eagle. It ended up with a new and improved dual-ignition HEMI engine

that delivers 370 horsepower and 398 lb-ft of torque with the 5-speed automatic AutoStick,

while the available 6-speed manual transmission increases output to 375 horsepower and a

whopping 404 lb-ft of torque – 30-35 more horsepower. Paired with AutoStick,

the HEMI

MDS system uses sophisticated algorithms to seamlessly transition from eight cylinders to

four when full power is not required, providing four percent better fuel mileage. The 6.1-liter

SRT HEMI V8

sends a corralled stampede of 425 horses straight to the rear wheels. Its

throwback Hemi Orange engine block is a nod to where HEMI has been; the updated titanium

components within signal where HEMI is going.
