BMW revealed the updated version of its colour-changing car technology at the Consumer Electronics Show in Las Vegas, expanding the concept from black and white to a full colour palette.

Developed with technology company E Ink, the exterior of the colour-changing car is divided up into 240 segments that can be individually controlled.

Commenters weren't completely sold on the project, though one called it a "Great getaway car!"

"This is probably an indication that automobiles are at the end of their cultural significance when automakers only have novelty left as a marketing approach," wrote another.

"Earlier [BMW] models were excellent. New ones? Less so," said a third.
