The 2006 Chrysler 300c Srt8 emerged as a true embodiment of American muscle and luxury, echoing the spirit of the original HEMI®-powered Chrysler C300 from 1955, famously dubbed the “banker’s hot rod.” This high-performance sedan wasn’t just about straight-line speed; it was a meticulously engineered package delivering a potent combination of power, refined handling, and premium amenities. Introduced in 2005, the Chrysler 300C SRT8 immediately set a new benchmark for performance sedans, capturing the attention of enthusiasts and critics alike.
The Heart of the Beast: 6.1-Liter HEMI V-8 Engine
At the core of the Chrysler 300C SRT8 lies the formidable 6.1-liter HEMI V-8 engine. This powerplant was the first to grace an SRT vehicle and represented a significant leap in performance over the standard 5.7-liter HEMI. Boasting 425 horsepower (317 kW), it delivered a staggering 85 horsepower increase – a 25 percent power surge – making it the most powerful naturally aspirated V-8 engine Chrysler Group had ever offered at the time, even surpassing the legendary 1966 “Street HEMI” in horsepower-per-liter rating. Torque was equally impressive, registering at 420 lb.-ft. (569 N•m).

The engineering behind this powerhouse was rooted in HEMI tradition, particularly the hemispherical combustion chambers renowned for their power and efficiency. SRT engineers honored this legacy while pushing the boundaries of performance. They achieved the increased output through several key enhancements:
- Increased Displacement: By boring out the cylinder diameter by 3.5 millimeters, displacement grew from 5.7 liters to 6.1 liters.
- Higher Compression Ratio: The compression ratio was raised from 9.6:1 to 10.3:1, improving engine efficiency and power generation.
- Optimized Airflow: Redesigned cylinder heads with larger-diameter valves and reshaped ports, a custom intake manifold with shorter runners, and exhaust headers with individual stainless steel-encased tubes all contributed to enhanced engine breathing. A larger diameter exhaust system (2.75-inch) with 3.5-inch chrome tips facilitated efficient exhaust flow.
- Performance Camshaft and Higher Engine Speed: Performance-oriented camshaft profiles allowed for greater air intake and exhaust, while the engine’s peak power output speed was increased by nearly 20 percent to 6,000 rpm. Lightweight hollow intake and sodium-filled exhaust valve stems aided in heat dissipation.
To handle the increased power, the 6.1-liter HEMI was fortified with robust components, including a reinforced engine block, forged steel crankshaft, high-strength powdered-metal connecting rods, oil-cooled floating-pin pistons, and a modified oil pan for efficient oil return at high speeds.
The engine’s power was managed by a five-speed automatic transmission featuring driver-selectable AutoStick®, offering both automatic and manual shifting modes. A heavy-duty prop shaft directed torque to an upgraded differential and axles, ensuring durability and performance.
Ride and Handling: Engineered for Dynamic Performance
The Chrysler 300C SRT8 was meticulously tuned to deliver exceptional ride and handling across a spectrum of driving conditions. SRT engineers focused on creating a balanced chassis setup that would excel in both everyday driving and spirited performance scenarios.

Key enhancements to the ride and handling included:
- Performance-Tuned Suspension: Specially tuned dampers, tailored spring rates, and suspension bushings, along with larger diameter anti-sway bars, provided a firm yet controlled ride.
- Lowered Ride Height: New front and rear suspension knuckles lowered the ride height by one-half inch compared to the standard Chrysler 300C, improving aerodynamics and handling.
- Enhanced Electronic Stability Program (ESP): The ESP system was specifically calibrated to complement the Chrysler 300C SRT8’s performance handling characteristics, offering a balance of stability and driver engagement.
- 20-inch Forged Aluminum Wheels and High-Performance Tires: The Chrysler 300C SRT8 rolled on striking 20-inch forged aluminum wheels wrapped in high-performance Goodyear F1 three-season tires (four-season tires were optional), with staggered dimensions of 245/45/20 front and 255/45/20 rear for optimal grip and handling balance.
Braking Power: Benchmark Performance
Matching its impressive acceleration and speed, the Chrysler 300C SRT8 featured a braking system engineered for predictable and powerful stopping performance. SRT aimed for benchmark braking capabilities, setting a new standard for sedans in its class.

The braking system incorporated high-performance Brembo calipers on all four wheels, renowned in racing and high-performance applications. These calipers featured four pistons for consistent clamping force. The front rotors measured 360 x 32 mm vented, while the rear rotors were 350 x 28 mm vented. This robust system enabled the Chrysler 300C SRT8 to achieve a 60-0 mph stopping distance in approximately 110 feet and a 0-100-0 mph time in the mid-16-second range.
Interior Refinement: Performance and Luxury Combined
The interior of the Chrysler 300C SRT8 seamlessly blended high-performance cues with premium comfort and amenities. Power-adjustable sport seats in the front, featuring performance suede inserts (mirrored in the rear seats), provided enhanced support during spirited driving. Heated front seats with memory functions, coupled with an adjustable pedal cluster, ensured personalized comfort for every driver.

“Technical” leather trim adorned the steering wheel, shifter, and door pulls, offering a positive grip. SRT-specific trim accents were present on the steering wheel, door pulls, door trim, and center stack, adding to the unique ambiance. The instrument cluster featured comprehensive gauges, including a 180-mph (300 kph) speedometer, tachometer, and temperature gauges. A tire pressure monitoring display was standard for the 2006 model year.
Standard premium amenities included an AM/FM stereo with a six-disc CD changer and a six-speaker Boston Acoustics sound system with steering wheel-mounted controls. New options for 2006 included a 13-speaker Kicker audio system with a powerful amplifier and subwoofer, and a rear-seat DVD system with a flip-up screen. SIRIUS Satellite Radio and UConnect™ hands-free communication with Bluetooth™ technology were also available. Automatic dual-zone temperature control and an electronic vehicle information center with customizable features further enhanced the cabin experience. The interior color scheme was offered in Light Graystone/Dark Slate.
Exterior Styling: SRT DNA with Sophistication
The exterior design of the Chrysler 300C SRT8 clearly communicated its Street and Racing Technology DNA while maintaining the Chrysler brand’s sophisticated aesthetic. Modified front and rear fascias incorporated unique ducts to channel airflow for brake cooling. A specially designed rear deck spoiler, while refined in appearance, contributed to a 39 percent increase in rear downforce without increasing drag.
