This Year’s
Winning Autos

The Audi E-tron is the company’s first electric vehicle with a clean-sheet design, and it’s a science fair on wheels, with 300 all-wheel-drive kilowatts (402 horsepower) and 400 kilometers (248 miles) of range by European standards. (The less-generous U.S. estimate should come in at around 200 miles.) But although this electric SUV is complex, its operational mantra is ease and simplicity.

Each axle, front and rear, gets its own electric motor, to enable the all-wheel-drive that Audi fans demand. The 95-kilowatt-hour battery, built at E-tron’s factory in Belgium, packs 36 shoebox-size cells from LG into a rigidity-boosting structural member.

Engineers probe the performance of noisy bits that, when working together, may solve some problems better than quantum computers.

A large universal quantum computer is still an engineering dream, but machines designed to leverage quantum effects to solve specific classes of problems—such as D-wave’s computers—are alive and well. But an unlikely rival could challenge these specialized machines: computers built from purposely noisy parts.

This week at the IEEE International Electron Device Meeting (IEDM 2022), engineers unveiled several advances that bring a large-scale probabilistic computer closer to reality than ever before.

NYU Researchers Pave the Way for Future Shared Mobility

The C2SMART Center at NYU is tackling the most pressing issues in urban transportation

NYU researchers led by civil and urban engineering professor Joseph Chow are working in the area of micromobility, a category of transit that includes electric bicycles and scooters, which has grown in popularity in cities around the world.

The collection of technologies and markets that comprise so-called "shared mobility" now constitutes a $60 billion market, according to some estimates. This enormous growth has at least in part been driven by the aim of reducing vehicle carbon emissions to address climate change concerns.
