Luminar lidar sensor aims to detect if you’re sipping a latte or crossing a road

The Volvo 360c concept unveiled in September 2018 previews the autonomous future of commuting. The Swedish automaker reaffirmed its commitment to building a fully autonomous car — one without pedals or a steering wheel — after 2021, and it has teamed up with sensor expert Luminar Technologies to reach its goal quickly, safely, and reliably.

“For the 360c to go from vision to reality, technology needs to be developed, legislation will need to evolve, and consumers need to be able to trust autonomy with proven safety,” Luminar Technologies explained. The company believes it has made a major a breakthrough in sensor technology that allows an autonomous car to see and identify objects located over 250 yards away.

Developed as a new technology from the ground up, Luminar’s lidar boasts a range that’s 10 times greater than the units currently in production. This gives an autonomous car like the 360c (pictured) the ability to identify objects at freeway speeds and react in a timely manner. For example, if a broken-down car is blocking a lane, a car equipped with Luminar’s latest lidar has the ability to see it, reduce its speed, and move over to the next lane in order to drive around it — just like a human driver would. The sooner a car analyzes a situation, the better it will handle it.

Luminar founder and CEO Austin Russel noted his firm’s lidar can also detect human shapes and actions, and it’s able to identify body parts like arms and legs. That means it can, in theory, tell whether a pedestrian is sitting down on a bench enjoying a latte or waiting to cross a busy road. Armed with this information, the car can decide whether to slow down and let the pedestrian cross or whether to keep going.

The breakthrough in sensor technology helps solve the first part of the autonomous car equation: technology. Ultimately, when autonomous cars will merge into the mainstream depends on when they’re legally allowed to carry passengers and when motorists feel comfortable giving up driving. Volvo wants to start an industry-wide conversation to solve these problems in a timely manner.

Henrik Green, Volvo’s vice president of research and development, told Digital Trends the firm aims to build a fully autonomous car on the as-of-yet-unveiled SPA2 platform after 2021. Volvo and Luminar both declined to provide a more specific time frame, but they stressed advancements like the new lidar speed up the development process. “Regardless of the ultimate timeline, Luminar will be able to accelerate the industry by at least five years and have fully autonomous vehicle platforms that work in city environments,” the company promised.

Volvo and Luminar will showcase their new sensor technology during the 2018 Los Angeles Auto Show. While Volvo isn’t bringing a single car to the event, it will have plenty to talk about.

The state of solid-state batteries: We may be on the cusp of an EV revolution
Factorial solid-state battery

Electric vehicles may have become a whole lot more popular over the past five years or so, but that’s despite some issues they still face regarding things like limited range and slow charging speeds. The result of these issues is that plenty of buyers are unsure about whether an EV might be for them. But there’s one technology that has been hailed as a savior for all of the EV issues related to batteries, and that’s solid-state battery tech.

This technology has been so hyped for so long that, at this point in time, it seems not only almost mythical, but as if we might never actually see it in the real world. So, what’s the state of solid-state batteries right now, and how far are we from finally seeing them and reaping their rewards? Here’s a look.
What are solid-state batteries?
What is a solid-state battery in the first place? Solid-state batteries keep the fundamentals of traditional battery design, offering an anode and a cathode with a porous separator in the middle, and a substance through which electrons flow from one side to the other. This, in turn, creates a circuit. But while a conventional battery is built with a liquid electrolyte solution on the inside, a solid-state battery instead makes the separator between the anode and the cathode the electrolyte itself.

Audi RS e-Tron GT Performance unveiled as a 912-hp electric sedan
2025 audi rs e tron gt performance specs pictures features

Audi's roster of past high-performance models includes the rally-winning Quattro and the V10-powered R8, but the new RS E-Tron GT Performance outguns them all. With up to 912 horsepower on tap, this electric sedan stands proud as the most powerful Audi ever built.

Starting with the RS E-Tron GT, which is related to the Porsche Taycan, engineers updated the front axle's electric motor and integrated a new, lighter electric motor into the rear axle to reach the 912-horsepower figure. Audi notes that this mammoth amount of power can only be unlocked temporarily when the launch control function is engaged, however. Other improvements helped the German company add horses to the E-Tron's cavalry, including a new chemistry for the 105-kilowatt-hour lithium-ion battery pack's cells and a revised cooling system.

Ram 1500 REV vs. Ford F-150 Lightning: Classic trucks go electric
Ford F-150 Lightning

The first Ram electric pickup truck is on the way. The Ram 1500 REV is set to be one of the most desirable electric trucks out there, thanks not only to the Ram name but also to its high-end specifications.

But, of course, it's certainly not the first electric truck out there. The Ford F-150 Lightning is a favorite among electric truck buyers, thanks to the fact that it continues that Ford F-150 legacy with a tried-and-true design coupled with new technologies.
