It has been one year since the discontinuation of the modern-day Dodge Challenger. With that being said, this week, we are looking back at our favorite versions of the modern-day Challenger, and the Dodge Challenger SRT-10 Concept is one of the most intriguing entries in the model’s storied history. Revealed in 2009, it was a bold experiment that combined a classic muscle car formula with cutting-edge engineering from Dodge’s performance division, Street and Racing Technology (SRT).
Powertrain and Performance –
At the heart of the Challenger SRT-10 Concept was a massive 8.4-liter V10 engine borrowed from the Dodge Viper. Producing 600 horsepower and 560 lb.-ft of torque, this powerhouse was mated to a Tremec TR-6060 six-speed manual transmission. The drivetrain setup included a 3.73:1 final drive ratio and a torque-sensing limited-slip differential, ensuring the Challenger could put its power to the ground effectively.
The engineering team didn’t stop at just boosting power. They adapted the Viper’s gear ratios and enhanced the Challenger’s driveline components, including a single-piece steel driveshaft and an all-aluminum differential, to handle the immense torque produced by the V10 engine. This configuration delivered thrilling acceleration and a visceral driving experience.
Suspension and Handling –
SRT engineers worked extensively to ensure the Challenger SRT-10 Concept was more than a straight-line missile. The car featured a significantly retuned suspension based on the 2009 Challenger SRT-8. The front included a multi-link short- and long-arm (SLA) setup with Bilstein mono-tube shocks, while the rear boasted an independent five-link suspension. Stiffer spring rates, a larger rear sway bar, reduced unsprung mass, improved handling, and improved ride quality.
To keep things under control during aggressive driving, the car’s braking system featured six-piston Brembo® calipers up front and four-piston calipers in the rear, paired with large two-piece vented rotors—390mm at the front and 355mm at the rear. The Challenger rolled on unique Alcoa forged aluminum wheels, measuring 20-inch x 9-inch in the front and 20-inch x 10-inch in the rear, wrapped in Pirelli P-Zero performance tires.
Exterior Design –
The Challenger SRT-10 Concept showcased a striking design with Tornado Red paint and a carbon-fiber hood and deck lid. Aerodynamic elements like a front splitter and a rear spoiler—inspired by the Dodge Viper ACR—enhanced downforce and high-speed stability. The hood featured a shaker-style intake system, providing both functional cooling and an iconic muscle car aesthetic.
Inside, the Challenger SRT-10 Concept combined race-inspired features with premium materials. Leather seats with additional bolstering and red-stitched accents matched the performance-oriented theme. Carbon-fiber accents adorned the interior, and the iconic red push-button starter from the Viper added a special touch. The instrumentation included a 180-mph speedometer and a large tachometer to monitor engine performance.
Legacy –
Although the Challenger SRT-10 Concept never made it to production, it demonstrated the potential of the modern Challenger platform. The experiment with high-performance engineering and bold styling laid the groundwork for future models like the 707-horsepower Challenger SRT HELLCAT and its successors. The Challenger SRT-10 Concept remains a fan-favorite, symbolizing the daring spirit of Dodge and its commitment to pushing boundaries in the muscle car segment.
