The 2024 Dodge Charger Daytona EV will come equipped with the Fratzonic Chambered Exhaust system, which is designed to replicate the sensory experience of a V-8 engine in an electric vehicle. The system generates the sound and vibrations typically associated with muscle car rumble by adding noise, vibration, and harshness back into the driving experience. This is intended to appeal to traditional enthusiasts who appreciate the visceral feedback of a powerful engine.
The Fratzonic Chambered Exhaust functions as a noise-and-vibration-generating unit, utilizing custom-designed elastomer isolator bushings and high-efficiency transducers to create the desired sound profile. The system is similar in design to a subwoofer box but is patented for its unique combination of components. It operates primarily from an external unit at the back of the car, with some additional active noise management integrated throughout the vehicle.
The development team behind the Charger Daytona EV focused on making the system as loud and authentic as possible, aiming to capture the essence of a Dodge V-8 engine. By sampling various historical V-8 engines and evaluating different sound themes, they were able to create a low-frequency growl with a futuristic edge that closely mimics the original engine’s tone. The system is tuned to operate at 38 Hz, similar to the firing order of a Hemi engine, giving it a familiar sound to the driver.
The sound profile of the Fratzonic system is influenced by various driving parameters, including vehicle speed, motor speed, throttle position, and drive mode. Different drive modes can adjust the amplitude and volume of the sound to suit the driver’s preferences, with the ability to turn the sound off completely if desired. The system is powered by a dedicated 600-watt amplifier and energy consumption is comparable to that of a high-end audio system.
While the Fratzonic Chambered Exhaust system was developed specifically for the Dodge Charger Daytona EV, there is potential for it to be adapted for other vehicles in the future. However, the current focus is on creating a unique and immersive driving experience for Dodge muscle cars. The team behind the system aims to continue developing and refining the technology to enhance the EV market and provide a sense of familiarity for enthusiasts transitioning to electric vehicles.
Overall, the Fratzonic Chambered Exhaust system represents a significant innovation in the electric vehicle industry by bringing back the sensory experience of a V-8 engine to the Dodge Charger Daytona EV. By carefully engineering the noise, vibration, and harshness components, the system provides a unique and immersive driving experience that sets it apart from other electric vehicles on the market. As the EV market evolves, this type of technology may become increasingly important in maintaining the appeal of muscle cars and bridging the gap between traditional and modern automotive enthusiasts.
