Pentagram aims to cut through the noise of EV sound design

What does an electric vehicle sound like when it goes from 0 to 60, when it signals a turn, when it’s powered down for the night? EV motors have fewer parts and are therefore incredibly silent, which presents safety concerns for drivers who recognize speed by sound and pedestrians who canÂ’t hear an approaching vehicle.  In 2019, regulators in Europe and the U.S. began requiring EVs to have warning sounds, but they left it up to the car manufacturers to choose those sounds. Many have taken the new legislation as an opportunity to not only create a branded sound, but also to stir up some marketing hype by enlisting famous musicians to compose the noise of an electric engine. Hans Zimmer created the Blade Runner-esque sound concept for BMWÂ’s i4 electric sedan, and, strangely, Linkin Park is creating EV sounds for BMW.  Sound designer Yuri Suzuki, a partner at design consultancy firm Pentagram, recently conducted a research project into the crucial role electric car sound has on a userÂ’s safety, enjoyability, communication and brand recognition, out of which he developed a range of car sounds. Suzuki says that while some automakers have chosen beautiful and interesting car sound designs, chasing celebrity clout is not the way to go when designing the sound behind serious machines.  “We really have to design carefully based on the psychological effects on a human,” Suzuki told TechCrunch. “ItÂ’s all about the relation between the human being and the machine itself.” Suzuki says smart sound design can help ease the difference between human and car by providing a shared language. Based on surveys he conducted, Suzuki came up with two new skeuomorphic electric engine sounds as well as adaptive sounds that reflect the time of day and the location of the drive.  His engine sounds are reminiscent of internal combustion engine revs, providing both drivers and pedestrians with a recognizable indication of speed increasing and decreasing. The sounds are placed at different pitches: one quite low, like a spaceship taking off; the other a bit higher, like a hovercraft vertically ascending. Audi, Ford and Jaguar Land Rover have also chosen to make futuristic copies of gasoline engines for some of their new electric vehicles.  SuzukiÂ’s sound design also includes in-car sounds, like powering on, turn signals or horn honking, that use AI to adapt to the time of day.

Drive pits Ariel Nomad against Suzuki bike

Ariel introduced the Nomad at the beginning of the year, which is basically an Atom converted to sand-rail duty with the addition of features like a composite cage and waterproof cockpit, Hella light bar, and Ohlins suspension with hydraulic bump stops. Evo reviewed it not long after, now Drive has got hold of it and put Steve Sutcliffe at the wheel, sending him to the Sweet Lamb Rally Center in Wales. The Nomad in this guise also gets a winch and BF Goodrich tires with a rear high-mounted spare. The motor is a US-spec, 2.4-liter Honda unit tuned to 240 horsepower and 235 pound-feet of torque, all going to the rear wheels only. The weight is just 1,477 pounds. For kicks, they sent Northern Irish motocrosser Graeme Irwin along to give Sutcliffe a point of reference. We're used to seeing cars battle bikes, and unless it's wet or the race goes to beyond 200 miles per hour the bike almost always takes it. Irwin was on his Suzuki RMZ-450, a bike with about 60 hp, but that, combined with Irwin's skills, was plenty enough to keep Sutcliffe hard at work. You can watch the dust fly in the video above.

Japanese motorcycles moving into forced induction

While turbocharging and supercharging may be nothing new in the automotive industry, motorcycle engines are almost always naturally aspirated. But even that's beginning to change. At the Tokyo Motor Show last week, two major Japanese companies showed off new forced-induction motorbike engines.
Kawasaki rolled in with a supercharged four-cylinder motorbike engine. It offered little in the way of details, disclosing only that the turbine blades were developed in-house to withstand the heat and vibration of spooling up at motorbike speeds.
Suzuki is taking a different approach, however. Its Recursion concept bike packs a turbocharged 588cc two-cylinder engine with a turbocharger and intercooler. The compact package churns out just under 100 horsepower and 74 pound-feet of torque, packaged into a motorbike that weighs just 384 pounds dry.
