How Peugeot keeps its new radar ‘under the radar’

Using rare alloy indium, Peugeot manages to evolve technology used for the humble car emblem

Adaptive cruise control. Lane keeping assist. Automatic emergency braking. We could list off 310 other modern “driver assistance” technologies, but the point is, to make all of the wizardry happen, vehicles often gain unsightly radar bumps, camera pods, and sensors.

Peugeot engineers thought there must be a better way: hide as much as possible behind the front emblem.

Problem? You can’t just put your radar behind a badge and expect it to work.
