EU finds Jeep Grand Cherokee and Suzuki Vitara break emissions rules

AMSTERDAM — Fiat Chrysler's Jeep Grand Cherokee and Suzuki's Vitara diesel models both break emissions rules and must be fixed or face a ban on sales across Europe, the Dutch road authority ruled on Thursday. The RDW authority, acting as the reference regulator for across the European Union, said Jeep had developed a software fix and that the authority had ordered the company to recall the model across Europe to roll it out. It added Suzuki had yet to find a credible solution for the Vitara. "Suzuki must come with adequate improvement measures or the RDW will begin the process of revoking its European type approval," the RDW said in a statement, adding it had also started the process of revoking approval for the Jeep Grand Cherokee as a "precautionary measure." Regulators across the world have been testing diesel models since Volkswagen admitted in 2015 that it used illegal software to cheat U.S. emissions tests. The RDW said it had found both the Jeep Grand Cherokee and Vitara had used "prohibited emissions strategies" that led them to emit higher levels of harmful nitrogen oxide (NOx) on the road than under testing conditions. Dutch State Secretary for Infrastructure, Stientje van Veldhoven, said in a letter to parliament she would inform prosecutors of the RDW's findings. Fiat Chrysler and Suzuki could not immediately be reached for comment. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.
