Zoox has given its custom-built robotaxi a makeover— and not just to make it look sharper. The Amazon-owned company revealed Wednesday a series of upgrades to the comfort and function of its electric, autonomous vehicle based on rider feedback and ahead of what it hopes will be a commercial launch later this year.

The core features of the Zoox robotaxi remain. The cube-like electric, autonomous robotaxi still lacks a steering wheel and other controls. The company kept the moonroof and starry night lights as well as the 40 cameras, radars, lidars, and infrared sensors, which help the robotaxi perceive the environment around it. And the vehicle still drives bidirectionally, has four-wheel steering, and can transport four people at speeds of up to 75 miles per hour.

Instead, Zoox has made a series of design and product tweaks required for a robotaxi that shuttles thousands of riders. At least, that is Zoox’s hope. On the inside, Zoox has added more padding and ergonomic curves to both the seats and headrests, and updated the color, material, and finish with a lighter palette of aloe-green seating and stone-grey flooring and trim.

The lighter color palette creates a calmer environment, according to Zoox. It also provides the kind of contrasting backdrop that makes it easy to spot common objects, like smartphones. Other interior changes include adding fluting on the charging pad to keep phones in place, enlarging the cupholders, and a more visible touchscreen.

On the outside, Zoox has relocated its bidirectional reflectors for better visibility and added a new speaker and microphone to the door interface as well as two-way audio capabilities. The company said the upgrades will improve communication with riders and other road users, as well as between Zoox Support and first responders.
