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.

Funning around with ZF's Smart, Advanced Urban Vehicles

ZF has a lot of experience building various electric vehicle parts, including transmissions, but it doesn't put them all together into one cute little package that often. The ZF Advanced Urban Vehicle changes that, and shows what the company can do when it takes bits and pieces of its admittedly cool tech and throws them all into the shell of an old Suzuki Swift. We got to control the all-electric beast at an event in Germany this summer, using nothing but a connected iPad. There were three headline technologies on the AUV (also called the Smart Urban Vehicle): the remote control Smart Parking Assist function, the all-electric rear-axle drive electric Twist Beam (eTB), and the PreVision Cloud Assist. PreVision Cloud Assist ZF had a short track set up for us to try out the PreVision Cloud Assist. The first time around the track, nothing was different. It's not supposed to be. The trick with Cloud Assist is that the car saves real-world driver interactions into its memory and, with the addition of GPS coordinates, starts to learn how to drive the route. Go to work the same way every day? If you're being assisted by a cloud, then all you have to do is steer. The car learns how fast it can take a turn and when it needs to slow down, with the idea here is to let the car move when it can, increasing the efficiency and range of an EV. You're still in charge in case of traffic ahead, but in open road circumstances, you won't need to touch the brakes or the gas. Just the steering wheel. On my second time around the demo track (which had data from other drivers who had tested the car earlier in the day), I kept my feet off the pedals, and the darn thing worked. It slowed me down when necessary to make a curve, but kept me at a brisk pace that felt a bit too fast but was in fact totally appropriate. Electric Twist Beam There's another bit of cool tech hidden near the front wheels. The car uses a MacPherson strut that was modified to offer a wider steering angle, up to 75 degrees, to be exact. ZF calls this the electric Twist Beam (eTB), and it gives the car an incredibly tight turning radius, about 6.5 meters. An axle like this could go into an EV or an ICE vehicle, but it makes a lot of sense in an electric car since it does have a major problem: it can't be powered. No worries, thought ZF engineers, who made the little SUV rear-wheel-drive by adding two electric motors.

Junkyard Gem: 2008 Suzuki Reno

Next time you're hosting a car-trivia night at your local junkyard/bar (hey, such places exist), you might try to stump your guests with a really tough one: What was the last US-market car to be designed entirely by Daewoo prior to the GM takeover? Sure, Americans could buy the Daewoo-badged Lanos, Nubira, and Leganza for a few years in the early 2000s, and the Verona was really just a slightly updated Leganza with Suzuki badges pasted on. The Chevy Aveo/Pontiac G3 was the descendant of the Lanos, but that special Daewoo sauce had been diluted by other GM flavors by the time it hit our shores. I say the answer is the Daewoo Lacetti — yes, that Lacetti — which was sold in the United States as the Suzuki Forenza (in sedan form) and Suzuki Reno (as a hatchback). Here's an example of one of the very last Renos you could buy here, found in a car graveyard near Denver, Colorado. The South Korea-built Reno never made much of an impression on the reviewers at this — or, I'm pretty sure, any — publication, despite having been styled by Giugiaro, though it was very reasonably priced during its 2005-2008 American sales run. My only experience driving the Reno comes from the time I rented one in South Carolina for just $9.98 a day. For that price, I thought it was a perfectly serviceable transportation appliance. Suzuki had been building cars for GM since the first Cultus hit American showrooms as the 1985 Chevrolet Sprint, and ties between the two companies became stronger as the 20th century became the 21st. They joined forces to buy bankrupt Daewoo in 2004, with American Suzuki selling the hastily-rebadged Nubira starting the next year. After a bit of excitement over the promising Suzuki Kizashi, American Suzuki filed for bankruptcy in 2012 and ceased selling cars here the following year. Don't feel too bad for Suzuki, though — in Japan, the company has had years of smash sales success with the Hustler, and of course Suzuki motorcycles and ATVs remain popular here. How much was this little Daewoo when new? With the base five-speed manual transmission, the MSRP on the base '08 Reno was $13,839, or about $19,425 in 2022 dollars. However, this car has the automatic transmission, an $1,100 option ($1,545 now).  You did get air conditioning and an AM/FM stereo in the base '08 Reno. This car has the optional CD player with AUX input. Honda had VTEC and Daewoo had D-TEC.
