8th March, 2005 Chrysler adds a 300C high-performance version to its international lineup
The new high-performance version of the already popular Chrysler 300C will begin to arrive in international showrooms in 2006 and will be available in both left- and right-hand drive. Because it will be available in RHD leads the Editor of Next Car to believe the 300C SRT8 will come to Australia. Sure, in Australia this new sporty Chrysler will be a low volume model. And that's the way it will be in all RHD markets! “The HEMI is a critical ingredient to the success of the Chrysler 300C,” said Dan Knott, Director — Street and Racing Technology (SRT), Chrysler Group. “With the new Chrysler 300C SRT8, we are now adding even more horsepower to the HEMI and even more performance to the Chrysler 300C.” Preliminary performance targets for the Chrysler 300C SRT8 are 0-100km/h in around 5-seconds, quarter-mile time (0.4 km) in the high 13-second range, and 0-160-0 km/h in the mid 16-second range. Top speed is electronically limited to 274 km/h. “With the Chrysler 300C SRT8, we’re delivering the ultimate performance sedan,” said Thomas Hausch, International Sales and Marketing. “With its world-class handling, benchmark braking, functional exterior enhancements, race-inspired interior appointments and a jaw-dropping 415 horsepower, we’re sure the 300C SRT8 will capture driving enthusiasts in Europe and other international markets when it goes on sale in 2006.” Powertrain The 415-horsepower SAE net, normally aspirated 6.1-litre HEMI engine is the highest specific-output engine ever offered by the Chrysler Group. Its 69.8 horsepower-per-litre rating exceeds even that of the legendary 1966 “Street HEMI.” Torque is rated at 410 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 Chrysler Group’s Street and Racing Team (SRT) set out to develop a more powerful HEMI for the Chrysler 300C SRT8, 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 SRT8’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 SRT8’s HEMI by 3.5 millimetres each, to increase the total displacement to 6.1 litres from 5.7 litres. 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 new Chrysler 300C SRT8’s 6.1-litre HEMI engine. Larger diameter valves and reshaped cylinder ports in the heads allow for maximised air flow. The intake manifold was designed with larger diameter runners for higher-speed tuning. Exhaust is routed through a larger-diameter (70 mm/2.75- inch vs. 63.5 mm/2.5-inch) exhaust system with 90 mm (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 per 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-litre 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-litre HEMI’s power is channeled through an A580 five-speed automatic transmission with specially calibrated AutoStick 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 SRT8 is conditioned for outstanding ride and handling across the dynamic range that customers are likely to experience. Chassis setup for the Chrysler 300C SRT8 is aimed at all-round performance with a number of enhancements, including tuned Bilstein 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 13 mm (one-half inch) from the Chrysler 300C. And, the Electronic Stability Programme (ESP) has been specially tuned for the SRT8’s performance handling characteristics. The Chrysler 300C SRT8 connects with the road via a new wheel and tyre assembly consisting of 20-inch forged aluminium wheels shod with high-performance Goodyear F1 three-season tyres (four-season tyres are an available option) with asymmetrical tread. Tyre 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 SRT8’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 SRT8 has 360 x 32 mm vented rotors, with 350 x 28 mm vented rotors in the rear. Design and amenities Befitting its high-performance character, the new Chrysler 300C SRT8 exterior styling is 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 SRT8’s exterior include body-colour front and rear bumper inserts, body-colour grille insert with chrome collar, body colour mirrors and door handles, and unique SRT badging. Two exterior colours are available: Bright Silver and Brilliant Black. The interior is offered in a Light Graystone/Dark Slate combination. Standard interior features of the Chrysler 300C SRT8 include front seats equipped with heat and memory functions, clad with performance suede inserts that secure occupants during spirited driving. Other features include an adjustable pedal cluster; “technical” leather trim on the steering wheel, shifter and door pulls; and special finishing on interior trim such as on the centre stack. Full instrumentation includes a 290 km/h (180 mph) speedometer, tachometer and temperature gauges. Premium amenities include a standard AM/FM stereo radio with six-disc CD changer powering a seven-speaker Boston Acoustics speaker system, with steering wheel-mounted controls. Also available as a Mopar aftermarket accessory is the UConnect™ hands-free communications system. The UConnect system uses Bluetooth® technology to provide wireless communication between the customer’s compatible mobile phone and the vehicle’s on-board audio receiver. Advanced voice recognition technology controls the UConnect operation, and incoming calls are broadcast through the vehicle’s audio speakers.
