Revving Up the Future: BMW's Electric M3 and the Evolution of Engine-Like Sounds in EVs
BMW is set to release an electric M3 with impressive specs, including four motors, all-wheel drive, and a battery pack over 100 kWh, delivering power ranging from 700 to 1,300 horsepower. To ensure the electric M3 feels like a true M car, BMW recorded the sounds of its inline-6, V8, and V10 engines, mapping the emotional arc of their acceleration onto the amplified noises from the electric motors. This approach mirrors Ferrari's use of an accelerometer to capture real vibrations from the Luce EV's motors and gears, turning vibration into sound by amplifying frequencies that sound good and filtering out unpleasant ones.
While the concept of creating engine-like sounds for electric vehicles is not new, BMW's approach with the electric M3 aims to provide an authentic driving experience by incorporating a rev-limiter chirp that adds to the overall appeal of the vehicle. In contrast, other manufacturers have taken different approaches, such as Jaguar's futuristic hum in the I-Pace and Hyundai's inclusion of fake gearshifts and rev limiters in its N models. Dodge, on the other hand, opted for a more aggressive sound with its Fratzonic system, which simulates exhaust-like noise in its electric muscle cars. Despite mixed industry-wide reception to synthesized engine noises in EVs, aftermarket companies have started selling V8 soundtrack kits for EVs, indicating a demand for engine-like sounds among some owners.
In conclusion, BMW's innovative approach to incorporating engine-like sounds in the electric M3, along with Ferrari's unique sound design for the Luce EV, showcases a growing trend in the industry to enhance the driving experience of electric vehicles through synthesized noises. While opinions on this practice vary, it is clear that manufacturers are exploring different ways to create a more engaging and authentic driving experience for EV owners.
