The electric vehicle revolution has brought many benefits, but one element that enthusiasts mourn is the disappearance of engine sounds. Lexus, known for creating some of the most emotionally stirring automotive acoustics in history, appears ready to tackle this challenge head-on with their upcoming flagship electric vehicle. The luxury brand is exploring ways to recreate the visceral audio experience that made their LFA supercar legendary.
The Art of Automotive Sound Design
Lexus has always understood that sound plays a crucial role in the driving experience. The engine and chassis for Lexus LFA was designed with acoustic performance in mind, with engineers focusing on what they called the “Angel Roar.” This attention to acoustic detail set Lexus apart from competitors and created an emotional connection between driver and machine.
The brand’s philosophy extends beyond simple noise generation. Only physical acoustic methods were utilized to give the driver a direct sensation of this engine’s characteristics. There is no electrical or electronic sound processing. This approach emphasized authenticity over artificial enhancement, creating sounds that felt genuine and connected to the vehicle’s mechanical operation.
Learning from the LFA Legacy
The Lexus LFA’s V10 engine remains one of the most celebrated powerplants in automotive history, not just for its performance but for its acoustic signature. Codenamed “1LR-GUE,” the musically tuned ten-cylinder mill revs to 9,500 rpm, creating a symphony that enthusiasts still celebrate today.
The engineer overseeing sound design at the time stressed the need to deliver solid first-, second-, and third-order sounds. This multi-layered approach to engine harmonics created complexity and richness that made the LFA’s exhaust note so memorable. The success of this acoustic engineering provides a template for recreating similar emotional responses in electric vehicles.
Modern Sound Engineering Techniques
Lexus has continued developing sound technology beyond the LFA era. No artificial sounds were created, but active noise cancellation helps mute undesirable noises. An intake sound generator and exhaust flaps deliver excitement while still meeting drive-by regs. This hybrid approach to sound management demonstrates the brand’s commitment to both regulation compliance and driver engagement.
The company’s recent work with the LC’s V8 engine shows their continued innovation in acoustic design. They’ve mastered the balance between meeting regulatory requirements and delivering emotional satisfaction, skills that translate directly to electric vehicle sound design.
The Electric Vehicle Sound Challenge
Electric vehicles present unique challenges for sound designers. Unlike traditional engines with mechanical components that naturally generate harmonics, electric motors produce minimal noise. This silence, while beneficial for noise pollution, removes an important sensory element from the driving experience.
Safety regulations also require electric vehicles to generate sounds at low speeds to warn pedestrians. Models equipped with automatically activated systems include the 2014 BMW i3 (option not available in the US), 2012 model year Toyota Camry Hybrid, 2012 Lexus CT200h, showing that Lexus has experience with mandatory warning sounds in hybrid applications.
Creating an Emotional Connection
The potential for Lexus to offer multiple engine sound options in their flagship electric vehicle represents more than just nostalgia. Different sounds can evoke different emotions and driving experiences. A V10 soundtrack might inspire spirited driving, while a more subdued tone could enhance relaxation during highway cruising.
This customization allows drivers to tailor their vehicle’s personality to match their mood or driving situation. The technology could potentially offer sounds inspired by famous Lexus engines, from the screaming LFA V10 to the smooth V8s that powered their luxury sedans.
Technical Implementation Possibilities
Modern electric vehicles possess sophisticated sound systems and processing power that make complex audio generation possible. Speakers strategically placed throughout the vehicle could create immersive soundscapes that respond to accelerator input, vehicle speed, and driving mode selection.
The system could integrate with the vehicle’s performance characteristics, ensuring that artificial sounds match the actual acceleration and power delivery. This synchronization maintains the authenticity that Lexus prioritized in their traditional engines.
Market Differentiation Strategy
Offering multiple engine sound options would differentiate Lexus from competitors who often provide single, generic electric vehicle sounds. This feature could attract traditional luxury car buyers who appreciate the emotional aspects of driving but want the benefits of electric propulsion.
The technology also positions Lexus as an innovator in the electric vehicle space while honoring their acoustic heritage. This balance between tradition and innovation aligns with the brand’s positioning as a luxury manufacturer that respects craftsmanship.
Future Development Potential
As electric vehicle technology matures, sound design may become an increasingly important differentiator. The EV supercar won’t have an exotic internal-combustion engine. Instead, its incredible performance will come courtesy of powerful electric motors, but it could still deliver the emotional impact through carefully crafted audio experiences.
The potential for downloadable sound packages, seasonal updates, or even collaborative soundtracks with audio engineers could create ongoing customer engagement. This approach transforms vehicle sound from a static characteristic into a dynamic, evolving feature.
Balancing Authenticity and Innovation
The challenge for Lexus lies in creating sounds that feel authentic while embracing the electric vehicle’s unique characteristics. Rather than simply mimicking traditional engines, the brand might develop entirely new acoustic signatures that celebrate electric propulsion while maintaining emotional resonance.
This approach could establish new standards for electric vehicle sound design, positioning Lexus as a leader in automotive acoustics for the electric age. The company’s track record with engine sound engineering provides credibility for tackling this complex challenge.
Frequently Asked Questions
Q: Will Lexus’s electric vehicle sound system work like traditional engine noise or will it be completely artificial?
A: Based on Lexus’s history with the LFA and recent LC models, they’re likely to avoid purely artificial sounds. The company has traditionally used physical acoustic methods and sound enhancement rather than electronic processing, so their electric vehicle system will probably blend authentic motor sounds with carefully engineered audio enhancement.
Q: What engine sounds might Lexus offer in their flagship electric vehicle?
A: While not officially confirmed, the possibilities could include sounds inspired by iconic Lexus engines like the LFA’s V10, various V8 configurations from their luxury sedans, or entirely new acoustic signatures designed specifically for electric vehicles. The “smorgasbord” approach suggests multiple options for different driving experiences.
Q: How would multiple engine sound options work in practice while driving?
A: The system would likely integrate with the vehicle’s drive mode selection, allowing drivers to choose different sound profiles for different situations. The sounds would synchronize with accelerator input, vehicle speed, and performance characteristics to maintain authenticity and avoid disconnect between audio and actual vehicle behavior.
Q: Are there safety or regulatory requirements for electric vehicle sounds that Lexus must consider?
A: Yes, electric vehicles must generate sounds at low speeds to warn pedestrians, and Lexus has experience with this from their hybrid models like the CT200h. Any sound system must comply with these safety requirements while also meeting noise regulations for residential areas and emissions testing facilities.
