Rivian’s autonomy chief says lidar is ‘very affordable’ and a ‘no-brainer’ decision

• Rivian unveiled a version of its coming R2 model that comes installed with lidar.
• The company said the sensor will support its future plans to roll out fully autonomous driving.
• Rivian's autonomy chief, James Philbin, told Business Insider that using the sensor is a "no-brainer."

For Rivian's chief of autonomy, the decision to put in lidar for the EV company's coming R2 SUV was obvious.

James Philbin, Rivian's VP of autonomy and AI, told Business Insider that the price of lidar has decreased significantly enough in recent years to be able to put the sensor inside a personally-owned, mass-production vehicle.

"It's been on this incredible cost curve, where 10 years ago, it would be just unimaginable that you could put a lidar on a consumer vehicle. And now it's getting into that price point, kind of in the range of a radar," Philbin said. Radar, a sensor that uses radio waves, is commonly seen in modern cars that have an advanced driver-assistance system (ADAS) or blind spot detection.

Lidar is a sensor that uses laser light to measure depth. While it's historically been used for topography, the sensor has gained more visibility in the automotive world with the advent of self-driving cars.

Most notably, Waymo's robotaxis have multiple lidar sensors, including the spinning lidar on the roof of the vehicle. Waymo has said that lidar provides additional safety to the vehicle's AI driver.

On Thursday, Rivian announced a road map to fully autonomous driving, which includes building an in-house chip and installing a lidar sensor in the company's coming SUV, the R2.

Philbin, who previously worked at Zoox and Waymo, told Business Insider that lidar makes an autonomous system "more robust" and can help the company get to its self-driving goal "faster."

"It's very affordable," he said. "The performance it gives you for that cost is really amazing. And so to me, it's kind of a no-brainer that you would want more sensors and more modalities for something that's so safety critical."

Using lidar diverges from the strategy of Rivian's main EV competitor, Tesla, which has taken a strong stance on pursuing self-driving with cameras only.

Tesla CEO Elon Musk once called lidar an expensive "crutch."

In the late 2000s, during the days of the Google Self-Driving Car Project, a single lidar unit could come with a five-figure price tag. Today, industry leaders say a similar unit could cost a few hundred dollars.

Rivian employees, including Philbin, did not disclose the cost of the lidar unit in the R2 when asked by Business Insider.

R2 will first be launched without the sensor in early 2026. It's slated to be Rivian's cheapest car to date, with a starting price of $45,000. The company aims to launch an R2 with lidar in late 2026.

When asked what the cost difference was to put a lidar in the R2, Philbin declined to comment but said that it was "not a significant consideration."
