General Motors Co.’s Cruise AV is a production-ready car designed with no manual controls and built to operate autonomously.
GM has asked the U.S. Dept. of Transportation for permission to begin testing the fourth-generation electric car on public roads in 2019. The company envisions users summoning one of the vehicles with a mobile app that also enables them to preset the car’s interior temperature and radio station settings before being picked up.
The Cruise AV lacks a steering wheel or foot pedals, but it otherwise resembles a conventional car inside with standard forward-facing seats. One key difference: The dashboard has none of the usual instruments. Instead, a center-mounted display screen sits atop a few manual controls for ventilation.
GM has equipped the Cruise AV with five laser sensors, multiple cameras and an array of short-range, long-range and articulating radars. The car is capable of checking its path 10 times per second, calculating multiple future paths simultaneously and anticipating the movement of nearby objects, according to the company.
Safety features include two main computers that operate simultaneously and act as backups for each other. The car also uses multiple methods of pinpointing the vehicle’s location. The steering and braking systems have redundant actuators, power sources and computerized controls.
The cars also will use “geo-fencing” techniques that restrict their operation to a geographic area. GM says the cars will operate only over roads for which it has high-definition mapping data and only under “known” operating conditions.

Mustang Changes for 2018
On Tuesday Ford unveiled—using the social media channels of actor Dwayne Johnson (this has got to unnerve some of the auto buff book editors)—the 2018 Mustang, which has undergone some modifications: under the hood (the 3.7-liter V6 is giving way to a 2.3-liter EcoBoost four, and a 10-speed automatic is available), on the dash (a 12-inch, all-digital LCD screen is available for the dashboard), at the tires (12 wheel choices), on the chassis (MagneRide damper technology is being offered with the Mustang Performance Package), and on the exterior (three new paint colors). And while on the subject of the exterior, there are some notable changes—a lower, remodeled hood, repositioned hood vents, new upper and lower front grilles, LED front lights, revised LED taillamps, new rear bumper and fascia.
