Dodge Charger EV patents noise generator

THE VISCERAL aural appeal of a high-performance combustion engine at full noise is arguably one of the big attractions for rusted on petrol heads. So, it comes as no surprise that Dodge has taken measures to ensure its new fully electric Dodge Charger Daytona muscle car coupe doesn’t let the team down in this area.

With the launch of its new Charger in ICE and EV, two- and four-door configurations imminent, the Stellantis brand has developed what it calls a Fratzonic Chambered Exhaust that is designed to let passengers and presumably bystanders “feel the rumble” from the new BEV blaster.

Dodge is so pleased with the noise generator that it has a patent-pending on the device that the company says delivers a signature rumble and tactile sound wave output “shattering preconceptions of a typical battery-electric vehicle”.

It is a high-tech means to a basic instinct end featuring “dual bespoke, high-efficiency extreme bandwidth transducers coupled with dual Fratzonic Chamber-loaded passive radiators, housed in a custom enclosure and powered by a dedicated amplifier”.

The “Frat” has been calibrated to work in concert with input from both driver and vehicle to create a deep rumble that Dodge says aligns with its DNA.

Inputs arrive from the accelerator pedal position, vehicle speed and torque output, to create the Charger’s “unique” exhaust personality, says Dodge.

“Distinct vehicle tones provide essential driver connection and feedback, including at track and at elevated speeds, enhancing the immersive in-car feel,” the company said in its press release.

The intensity of the Fratzonic Chambered Exhaust is linked to higher performance... Drag, Drift, Donut and Track modes deliver an elevated acoustic output, and the device also reacts to several dynamic vehicle events including power up/power down, idle/rev, acceleration/throttle and the interestingly named PowerShot.

A Full Stealth mod is also available.

Power outputs for the all-electric Charger are circa 500kW running 800V electric architecture and 375kW with a 400V system.

Two-door coupe versions of Charger Daytona R/T and Charger Daytona Scat Pack will begin production about now (Summer 2024 in the US), while production of four-door Daytona models will begin in the first half of 2025.

Additional to the BEV models, 3.0-litre straight six-cylinder petrol-powered two-door Dodge Charger Sixpack HO and four-door Dodge Charger Sixpack SO models are scheduled to begin production in the second half of 2025.

The twin turbocharged Hurricane engine is good for close on 400kW.

“The world’s first Fratzonic Chambered Exhaust brings the raw rumble of iconic Dodge muscle to the next-generation, all-electric Dodge Charger Daytona,” said Dodge CEO Matt McAlear.

“We know our Dodge enthusiasts want that visceral feel you get when you drive a Dodge muscle car, and the Charger’s new Fratzonic system delivers the adrenaline-pumping spirit that they expect.

“It reacts to specific inputs and driving events, giving the driver a direct connection to their new Charger. Simply put, when you hear it and feel it, you will know it’s a Dodge Charger Daytona.”

The Fratzonic name is inspired by the Dodge’s brand’s historic Fratzog logo, the new symbol of Dodge brand next-generation vehicles and prominently featured on the all-new Dodge Charger.
