Think Your Car Door Sounds Nice and Solid When It Slams? It’s Faked

Automotive
The sound of your car’s door slamming is a lie. A trick. A clever ruse. And it’s all thanks to the engineers who designed your car. Your car doors are carefully designed to sound sturdier than they really are, reports Mel. You can thank psychoacoustics for this practice, which is the study of the mind’s perception of different sounds. Here’s an example: Ever experience the satisfying thud of closing a 1980s BMW door? There’s a heft to those doors that makes them feel solid. Substantial. You’re safe here. This car is well-made. Yet we all know that even high-end cars have lost a lot of that extra heft, largely thanks to advances in automotive safety, as AutoBead co-founder James Ford explained to Mel: Engineering the sound of a car door…

This 3-Wheel Electric Scooter Runs on Solar Power and Will Easily Get You Out of Traffic Jams

Automotive
This is the BICAR, a three-wheel electric scooter that runs on solar power and designed for sharing using a shared mobility program. It was developed by a research team at the Zurich University of Applied Science, led by Adrian Burri and Hans-Jörg Dennig. The fully electric-powered scooter goes up to 28mph (45 km/h). The BICAR’s energy self-sufficiency is guaranteed with solar power and includes a back-up system with swappable batteries and newly-created Battery Swap Stations. Riders can use a mobile app to “geo-localize” a BICAR or a Battery Swap Station, make a reservation, lock/unlock the BICAR and use their mobile phone and software as an information board and navigation tool while driving, according to the team. BICAR-sharing for short and medium distance traveling within a city is ideal for businesses…

China to get the electric Buick Velite 7 this year, so maybe the U.S. will finally get the Chevrolet Bolt EUV. General Motors announced today that later this year, the Buick brand will launch in China the all-electric Buick Velite 7 “SUV”.

Suzuki, Toshiba, Denso EV battery plans to be pushed back due to the pandemic

Automotive
The India joint venture of Suzuki Motor, Toshiba and Denso is likely to put on hold plans for a second phase of its project to manufacture batteries for electric vehicles, even as the work on the first phase is currently behind schedule, people in the know said. Lack of a well-defined electric vehicle policy and a slowing market for such vehicles have led the joint venture, Automotive Electronics Power (AEPPL), to go slow on the second phase, one of the people said. Earlier, Korea’s LG Chemicals had put on hold its project to produce lithium-ion batteries in India in collaboration with the Mahindra Group. AEPPL said the first phase of the project was delayed by a few months due to operating and logistical hurdles posed by the Covid-19 pandemic and…
