China Could Drive Demand for Autonomous Cars, VW Exec Says

  China Could Drive Demand for Autonomous Cars, VW Exec Says The company anticipates regulations that could incentivize autonomous driving.China is the world's largest new-car market, so it already holds considerable sway over the decisions of automakers. But when it comes to self-driving cars, China could be particularly important, Christian Senger, Volkswagen's head of electric mobility told journalists at the 2018 Geneva Motor Show.

Car design is far from a purely aesthetic pursuit. In addition to accommodating all manner of engineering needs, designers must work within tight regulatory constraints. In our hyperregulated modern world, the government dictates nearly every aspect of car design, from the size and color of the exterior lighting elements to how sharp the creases stamped into sheetmetal can be. If a designer is lucky, those rules are the same in the United States and Europe. Often, though, they’re not, leading to designs that adhere to the stricter stipulations of the two rulebooks. Because, as Joe Grace, head of concepts and innovation at Fiat Chrysler Automobiles, notes, if a vehicle isn’t designed from the outset with both markets in mind, “even changing the plastic pieces can be expensive.” We also spoke with Robert Lesnik, director of exterior design for Mercedes-Benz, and Christopher Chapman, senior chief designer for Hyundai Design North America, about the surprising specificity of rules dictating the look of your new car.

This $10,000 3D-Printed Electric Car Will Be on the Market in 1 Year

  This $10,000 3D-Printed Electric Car Will Be on the Market in 1 Year Consumers in China will be able to buy mass-produced, 3D-printed electric cars for under $10,000 by Q2 2019. The Italian company X Electrical Vehicle (XEV) will team up with Polymaker, a manufacturer of 3-D printing materials, to make the LSEV, which XEV claims will be the first mass-produced 3D-printed car. The company says it has already received more than 7,000 orders for the cars from the Italian postal service and from ARVAL, a vehicle-leasing service. The cars top out at 70 kilometers per hour (a little under 45 MPH) and have a range of 150 kilometers (just over 90 miles). A designer for XEV told South China Morning Post that China was the biggest market for their cars, and the company is in talks to set up a production line on the mainland. The cars reportedly take around three days to manufacture. Everything visible on the car except the windows, chassis, and seats is 3D printed.

1. Sheetmetal Edges

Most pedestrians have no clue how much they’ve affected car design. European regulations attempting to cushion a person’s impact with a moving car have led to taller hoods, which provide for more space between the head of a struck pedestrian and any hard engine component. Hyundai’s Chapman says that means the design of a car is “set up” at the base of its A-pillar, with shoulderlines rising and greenhouses slimming from there.

There are even regulations regarding the creases in sheetmetal. As Mercedes-Benz’s Lesnik explains: “Everything that could hit a theoretical body or head has to be soft.” Any sharp exterior line is an illusion made possible by talented designers and precision manufacturing processes. EU law dictates a minimum 0.2-inch radius for all edges on the front and rear fascias, with a sharper 0.1-inch radius allowed for all other exposed body panels. Even grilles and badges—basically everything above the doorsills—must have blunted edges. But brush bars, protruding tow hooks, and front fenders that expose parts of the front tires, like those on the new Jeep Wrangler, are welcome in America. (In Europe, a different front bumper fills that gap on the Wrangler.)

These Tiny-Wheeled Car Renderings Are Terrifying

  These Tiny-Wheeled Car Renderings Are Terrifying Some things just shouldn’t exist. Remember those weird renderings from February of those cars with unnaturally tiny wheels? Well, we have more nightmare fuel for your dreams with some new renderings that are as weird and otherworldly as before. It’s hard not to imagine these tiny-wheeled cars existing in some alternate dystopian universe that’s artificially flat and smooth. Maybe these cars live in a world where potholes are myths?© Motor1.

2. Rear Bodywork

Designers also like to pull in the bodywork aft of the rear wheel-well cutouts to show off a little tire tread—the sports-car equivalent of a plunging neckline. But European regulations dictate that fenders must cover the entire tread width as measured from 30 degrees forward of the tire’s top center to 50 degrees rearward. Black plastic fins like those you’ll find on the Jaguar F-type allow stylists to create that provocative view while still adhering to the letter of the law.

The McLaren P1’s arcing taillights can’t get much thinner. U.S. law requires a minimum of 7.8 square inches of illuminated surface area per brake light, 1.9 square inches of which must be visible 45 degrees off the car’s center and 15 degrees below the taillight’s horizontal centerline.

California eyes driverless car testing with passengers

  California eyes driverless car testing with passengers Less than a month after Uber's fatal accident in Arizona, California regulators issue a proposal for a pilot test of passenger-carrying autonomous vehicles.The state's Public Utility Commission on Friday issued a proposal that would authorize a pilot test program for autonomous vehicle passenger service. One version of the program would allow testing with a driver, and one without a driver.

Well obviously that is true, but cars have to adhere to laws and type approval regulations , which gives certain constraints. The location will dictate the placement of the filler nozzle. Pingback: Designers Imagine how Apple Car Might Look Like | Joseph Park.

4. Turn Signals

U.S. regs allow automakers to use the same element as both taillight and turn signal. In Europe, the turn signals have to be separate and amber in color. Some designers suspect the U.S. will soon follow suit, a development that FCA’s Grace tells us he’d champion. And he’s already preparing for the change, as the 2019 Ram 1500 sports amber turn signals.

Audi’s sequential signals illuminate too small an area when they first fire up, so in the U.S., they’re combined with a standard turn signal. Each turn-signal lamp (or bank of LEDs) must cover at least 3.4 square inches.

The U.S. requires all vehicles to have marker lights—amber lights mounted to the front fenders or integrated into the sides of headlight housings and red lights on the rear fenders. Europe doesn’t mandate markers for any car less than 19.7 feet long but does require redundant turn signals be installed along the sides of the vehicle.
