Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Suzuki Jimny gets confused by American guardrails

The reborn Suzuki Jimny 4x4 has faced some crosswinds in the time it's been on the market: It earned only three stars in its Euro NCAP test due to a badly-inflating driver airbag and troubles with pedestrian protection. The automatic emergency braking function also had some issues in NCAP testing, but now the Jimny's AEB system is facing an another problem — it appears to be confused by guardrails. Two German-market Jimnys had been shipped to Los Angeles for the World Car of the Year testing, Australian journalists found that on some corners of the California test route, the AEB was seemingly triggered by a guardrail in a curve in the road. The problem was found with both Jimnys, and Suzuki's Jimny chief engineer was present to look into the matter; later, Suzuki engineers were able to replicate the glitch with these particular vehicles on the same road. While U.S. sales of the Jimny are extremely unlikely, test data acquired on American roads still seems to be highly valuable for Suzuki, as tests in Japan could not replicate the problem. It appears the road condition, tilt angle, curve aspects and vehicle speed all conspired to puzzle the AEB system, which is now being evaluated for a software or calibration change. The jerky correction by the electronic stability program, audible on the CarAdvice video, happened at 45-55 mph, which is not overly fast for even the narrow and tall Jimny — it is possible that the AEB mistook the guardrail for another car. Suzuki stated: "There is a possibility that the (stability control) is instantaneously switched on (by) reacting to the vehicle sway when departing the S-shaped curve — and then consecutively switches on because the vehicle is circling the curve at high speeds. [...] The intervention of the stability control may give a sense of discomfort to the driver but is not an event that would disturb the vehicle's direction of movement." The driver safety assists are a good addition to the Jimny, of course, given that the 1980s second-generation truck was the subject of a beef between Consumer Reports and Suzuki North America due to its reported tippiness in corners.

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.
