Koenigsegg introduces Quark Raxial Flux motor, David inverter and Terrier torque-vectoring e-drive unit

Green Car Congress

Even the rotor uses the renown Koenigsegg Aircore hollow carbon fiber technology (presently used in Koenigsegg’s rims, steering wheel, seats, etc). Weighing only 15 kg with a volume of 10 liters, the ultra-compact inverter kicks out 1300 ARMS AC at 850 V (DC) over 6 phases, with up to 750kW of power.

Chevrolet unveils Bolt EV Concept; 200+ electric miles for ~$30,000

Green Car Congress

The Bolt EV concept is also designed to support DC fast charging. The Bolt EV concept has practically no front or rear overhang; it thus makes the most of interior space and was designed to create a roomy environment for four that feels expansive. The modes adjust accelerator pedal mapping, vehicle ride height and suspension tuning.

Studying Climate Change with an Ice Radar Drone

Cars That Think

Modern instruments are often flown on de Havilland Canada DHC-6 Twin Otters, which are two-engine turboprops, or Basler BT-67s, which are modified Douglas DC-3s. Gathering more frequent data using just crewed flights is difficult—they are expensive and logistically challenging, and, in harsh environments, they put people at risk.
