Winning Autos

When I get my first knee-wobbling glimpse of the 488 Pista and its zesty racing stripes, I’m not thinking about technology, I have to confess. But when I strap aboard the Pista at Ferrari’s fabled Fiorano test circuit in Maranello, Italy, I’m soon saying grazie for the sheer technical prowess of the fastest V-8 Ferrari ever produced.

A midmounted, dry-sump, twin-turbo V-8 spools up 529 kilowatts (710 horsepower) from just 3.9 liters of displacement, in a Ferrari that weighs just 1,382 kilograms (3,047 pounds). That’s 6 percent lighter than a 488 GTB, the standard version of Ferrari’s midengine marvel. The diet that slimmed down the Pista included carbon-fiber wheels that weigh 40 percent less than standard rims.

For more than 25 years, Rory Cooper has been developing technology to improve the lives of people with disabilities.

Cooper began his work after a spinal cord injury in 1980 left him paralyzed from the waist down. First he modified the back brace he was required to wear. He then turned to building a better wheelchair and came up with an electric-powered version that helped its user stand up. He eventually discovered biomedical engineering and was inspired to focus his career on developing assistive technology. His inventions have helped countless wheelchair users get around with more ease and comfort.

The next wave of Moore’s Law will rely on a developing concept called system technology co-optimization, Ann B. Kelleher, general manager of technology development at Intel told IEEE Spectrum in an interview ahead of her plenary talk at the 2022 IEEE Electron Device Meeting.

“Moore’s Law is about increasing the integration of functions,” says Kelleher. “As we look forward into the next 10 to 20 years, there’s a pipeline full of innovation” that will continue the cadence of improved products every two years. That path includes the usual continued improvements in semiconductor processes and design, but system technology co-optimization (STCO) will make the biggest difference.

Solving Automotive Design Challenges With Simulation

Learn about low-frequency electromagnetic simulations and see a live demonstration of COMSOL Multiphysics software

1 min read

The development of new hybrid and battery electric vehicles introduces numerous design challenges. Many of these challenges are static or low-frequency electromagnetic by nature, as the devices involved in such designs are much smaller than the operating wavelength. Examples include sensors (such as MEMS sensors), transformers, and motors. Many of these challenges include multiple physics. For instance, sensors activated by acoustic energy as well as heat transfer in electric motors and power electronics combine low-frequency electromagnetic simulations with acoustic and heat transfer simulations, respectively.

Multiphysics simulation makes it possible to account for such phenomena in designs and can provide design engineers with the tools needed for developing products more effectively and optimizing device performance.
