6.1 l HEMI V8 / 425 PS / 570 NM



PEBBLE BEACH, Calif., Aug. 13 /PRNewswire-FirstCall/ -- With 85 more

horses under the hood, the momentum continues for the Chrysler 300 and its

legendary HEMI(R) engine. Today, the Chrysler Group revealed the 425-

horsepower 2005 Chrysler 300C SRT-8, which arrives in showrooms next spring.

"With a nearly 50 percent take rate, the HEMI is a critical ingredient to the success of the Chrysler 300," said Dan Knott, Director - Street and Racing

Technology (SRT). "With the new 2005 Chrysler 300C SRT-8, we are now adding even more horsepower to the HEMI and even more performance to the Chrysler 300C."

Preliminary performance targets for the 300C SRT-8 are 0-60 mph in the low 5-second range and quarter-mile time in the high 13-second range.


The 425-horsepower, normally aspirated 6.1-liter HEMI is the highest specific-output engine ever offered by the Chrysler Group. Its 69.8

horsepower-per-liter rating exceeds even that of the legendary 1966 "Street HEMI." Torque is rated at 420 lb.-ft.

Although the Chrysler HEMI was born in the 1950s and entered into legend in the 1960s and '70s, today's version took much of its inspiration from the

original -- particularly the namesake hemispherical combustion chambers that provide power and efficiency.

When SRT set out to develop a more powerful HEMI for the Chrysler 300C SRT-8, they were mindful of the engine's heritage, which led to adopting

traditional HEMI engine cues such as an orange-painted cylinder block and black valve covers.

The SRT powertrain engineers who developed the Chrysler 300C SRT-8's engine achieved more horsepower by adding more cubic inches, increasing the compression ratio, redesigning the cylinder head intake and exhaust systems for increased flow, and increasing engine speed.

To get more displacement, SRT engineers bored out the diameter of the cylinders in the Chrysler 300C SRT-8's HEMI by 3.5 millimeters each, to

increase the total displacement to 6.1 liters from 5.7 liters. Compression ratio was also increased to 10.3:1 from 9.6:1, unleashing more energy in the

combustion process.

Engine breathing was increased with new high-flow cylinder heads, a specially designed intake manifold, and exhaust "headers" with individual

tubes encased in a stainless steel shell, all unique to the 2005 Chrysler 300C SRT-8's 6.1-liter HEMI engine. Larger diameter valves and reshaped cylinder ports in the heads allow for maximized air flow. The intake manifold was designed with larger diameter runners for higher-speed tuning. Exhaust is routed through a larger-diameter (2.75-inch vs. 2.5-inch) exhaust system with 3.5-inch chrome tips.

Performance-oriented camshaft profiles were developed to balance total vehicle requirements, simultaneously allowing more air in and out of

cylinders. This increases performance and manages a higher engine speed, which is another method to increase horsepower. SRT engineers increased the

HEMI's peak engine speed nearly 15 percent, to 6,200 revolutions power minute (rpm) from 5,400 rpm. Intake and exhaust valve stems are hollow, and the exhaust valve stems are filled with sodium to help dissipate heat more efficiently.

The high-performance 6.1-liter HEMI is further strengthened with a host of redesigned components, including a reinforced engine block with increased

coolant flow, forged steel crankshaft, high-strength powdered-metal connecting rods, floating-pin pistons (cooled by oil squirters), and an oil pan modified for reduced oil foaming.

The 6.1-liter HEMI's power is channeled through an A580 five-speed automatic transmission with specially calibrated AutoStick(R) driver-

selectable range control, which offers fully automatic or manual shifting selection. A heavy-duty four-flange prop shaft sends the torque from the

transmission to an upgraded differential and axles.

Ride and Handling

The Chrysler 300C SRT-8 is conditioned for outstanding ride and handling across the dynamic range that customers are likely to experience.

Chassis setup for the Chrysler 300C SRT-8 is aimed at all-around performance with a number of enhancements, including tuned dampers, specially

tailored spring rates and suspension bushings and larger-diameter anti-sway bars. New front and rear suspension knuckles contribute to a ride height

lowered one-half inch from the Chrysler 300C. And, the Electronic Stability Program (ESP) has been specially tuned for the SRT-8's performance handling


The Chrysler 300C SRT-8 connects with the road via a new wheel and tire assembly consisting of 20-inch forged aluminum wheels shod with high-

performance Goodyear F1 three-season tires (four-season tires are an available option) with asymmetrical tread. Tire dimensions are a beefy 245/45/20 in the front, and 255/45/20 in the rear.

Braking performance goes hand-in-hand with the new Chrysler 300C SRT-8's outstanding accelerating and speed -- and the braking system was specially

designed to slow and stop the car safely and predictably. At the same time, this system was designed to provide benchmark braking performance, setting a new standard for sedans in its class.

All four wheels feature stout performance calipers developed by Brembo -- well-known in racing and high-performance circles -- equipped with four

pistons for even comparing performance. Up front, the Chrysler 300C SRT-8 has 360 x 32mm vented rotors, with 350 x 26mm vented rotors in the rear.


Befitting its high-performance character, the new 2005 Chrysler 300C SRT-8 exterior styling, in a sophisticated treatment that resonates with the

Chrysler brand's premium character.

Modified front and rear fascias help direct air flow, particularly through unique ducts that help cool the brakes. In addition, a specially designed

rear deck spoiler, while refined in appearance, is also functional -- increasing rear downforce by 39 percent without increasing drag.

Other unique touches to the Chrysler 300C SRT-8's exterior include body-color front and rear bumper inserts, body-color grille insert with chrome collar, body-color mirrors and door handles, and unique SRT badging.

Two exterior colors are available: Bright Silver and Brilliant Black.

Safety and Security Features

Following are safety and security features available on the Chrysler 300C


* Advanced Multi-Stage Air Bag System: Inflates with a force appropriate

to the severity of the impact. Includes Occupant Classification System (OCS)

* Anti-lock Brake System: Electronic sensors that help prevent wheel

lockup. The optional ABS system offers improved steering control under

extreme braking and/or slippery conditions

* Electronic Stability Program (ESP): This available feature aids the driver in maintaining vehicle directional stability, providing oversteer and understeer control to maintain vehicle behavior on various road surfaces

* Energy-Absorbing Steering Column: Manual-adjust telescoping steering

column includes two hydroformed coaxial tubes that move relative to each other, which allows the column to move forward and provide more energy absorption during an impact

* High Intensity Discharge (HID) Lighting: This available feature provides 70 percent more light to increase driver visibility, using XENON bulb


* Occupant Classification System (OCS): The OCS measures the conditions for activation or deactivation of the passenger-side front air bag based upon the weight of the occupant

* Rear Park Assist: This available ultrasonic rear obstacle detection system signals through an audible warning and a rear overhead display to avoid

potential collisions

wenn ich dann in (hoffentlich vielen jahren) einen neuen gebrauchten brauche (wortspiel ahoi) dann wird der 300c srt8 mit sicherheit in die ganz enge wahl kommen...

Naja, da wart ich nun so lange, erfahre das mein Hemi erst Ende September bei mir ist, und nun kommt man mit einem SRT raus.... Also sowas.

Da hab ich doch zu früh bestellt.

Nix für ungut!

Hm, wenn ich mir da vorstelle, die Chrysler Mannen werden bisserl übermütig und bauen den HEMI in der alten Grösse auch noch.

426 cui HEMI neu. Da würds wohl heissen: Gute Nacht für alles, was sich da alles als Konkurrenz dahertraut.
