Engineers at Ohio State University are developing a computer control system that improves the fuel efficiency of hybrid gasoline-electric vehicles. Road tests on a Chevy suburban SUV show a 50% increase in fuel efficiency. "The work demonstrates that energy-efficient hybrid cars can retain the high-performance feel of traditional gas-powered vehicles," says Giorgio Rizzoni, professor of mechanical engineering. Based on numerical simulations and in-vehicle tests, the engineers created a computerized control system that relies on algorithms for optimizing the power split between engine and electric motor.

Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
