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.

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.

Suzuki recalls nearly 61k SX4s and Kizashis for shifting out of Park

Suzuki has discovered an issue with the gearshift lever on some of its vehicles, and has issued a recall in coordination with the National Highway Traffic Safety Administration to address the problem. The issue affects the the 2010-2013 SX4 and Kizashi models fitted with automatic transmissions manufactured between specific dates in 2009 to 2012. In the affected vehicles, the shifter could slide out of the Park position without the brake pedal being depressed, which needless to say could lead to the vehicle unexpectedly rolling away. All told, the recall affects an estimated 60,823 vehicles, the owners of which can expect to head from the manufacturer to bring their Suzukis in to their local dealership to have the shift selector assembly replaced entirely, starting January 19. Since Suzuki no longer sells new cars in the US, owners looking for dealers and authorized service points are advised to check out the company's service provider website tool here.
