The newly revealed all-electric Lexus LFA Concept is joining the expanding lineup of performance EVs that feature artificial engine sounds. Project manager Takashi Doi confirmed this with a simple “of course,” adding that “sound creation and development is very important.”
Why devote resources to a feature that isn’t mechanically real? Automakers continue to combat the long-held perception that EVs are “boring.”
One current approach is to reintroduce emotional cues into the driving experience, including simulated engine noises and gear shifts. Since most EVs use a single-speed setup, they typically don’t shift at all, with notable exceptions like the Porsche Taycan, which uses a 2-speed rear motor.
Regarding simulated shifts, Doi was more measured. He acknowledged that fun and emotional engagement are important during development, but not at the expense of performance.
If artificial shifts compromise capability, like the simulated gears in the Hyundai Ioniq 5 N, which slightly reduce real-world acceleration, the feature may be omitted from the production model.
However, the Ioniq 5 N is far from underpowered. Porsche’s Frank Moser even commended the car’s abilities, particularly when using N Grin Boost. With that level of validation for Hyundai’s approach, Lexus could draw inspiration when designing its own performance-focused EV.
Artificial sound carries particular relevance for this model, following in the footsteps of the original Lexus LFA, widely celebrated as one of the best-sounding cars ever made, often mentioned alongside legends like the Porsche Carrera GT and Mazda 787B.
Its 4.8-liter 1LR-GUE V10, co-developed with Yamaha with acoustics in mind, became a defining feature, elevating the LFA from modest initial sales to a cult-status halo car.
Despite the V10’s iconic reputation, the engineering team may steer away from pure nostalgia, instead creating a fresh sound identity for the electric era. As Doi explained, “Whether we try to follow traditional engine sounds or start with something new, it’s something to decide.”
He also noted that the project’s sound design was a “directive of Morizo,” the racing alter ego of Akio Toyoda, chairman of Toyota Motor Corporation. The discipline of EV sound design has advanced so far that automakers such as BMW have collaborated with multi-Grammy winner Hans Zimmer to compose acceleration audio for vehicles like the i4.
Lexus has yet to announce a production schedule for the electric LFA. Nevertheless, it has been confirmed that the concept is being developed on a core aluminum performance platform linked to the GR GT and GR GT3 programs.
