Mary Barra thinks GM is a leader in autonomous tech

Saying General Motors is "among the leaders" in autonomous vehicle technology, CEO Mary Barra rapped about her company's driverless work in an interview with USA Today. Barra covered a number of topics, including well-known efforts, like Cadillac's upcoming Super Cruise technology, as well as hinting at "a lot of efforts that are confidential." "Things are moving quickly in autonomous [cars] because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," Barra said. "Next year we're going to have Super Cruise on one of our Cadillacs. On highways you'll be able to take your hands off the wheel and feet off the pedals – with a very creative way to make sure the driver is alert and involved in the driving process." As for those "confidential" efforts, feel free to speculate. GM has recently confirmed that it'd be running autonomous Volts at its Warren, MI tech center, which certainly indicates that the company is playing with much more than Super Cruise. GM will need to continue to embrace autonomous driving, owing to both traditional competitors like Toyota, as well as non-traditional opposition, like Google and Apple. Speaking of its competition from Silicon Valley, Barra was asked about two of the region's biggest names – Apple's Tim Cook and Tesla boss Elon Musk. "I have tremendous respect for Tim Cook, and I don't really think he needs advice from me," Barra told USA Today with a laugh. And when asked about Apple's future as a "viable competitor," she said, "I have no insights other than what I read in the papers. But it would be foolish for me not to assume that they're going to." As for Mr. Musk's openness about future products and how it contrasts with GM's relatively closed attitude, Barra also gave a chuckle. "I'm sure you would like me to say yes. I think we're fundamentally different. Look at our volume and look at the segments where we compete. His product line – his two products – his scale, it's completely different." The rest of Barra's interview is certainly worth a read, and includes talk about the Volkswagen diesel scandal, GM's changed relationship with the National Highway Traffic Safety Administration, and Uber.

Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

Junkyard Gem: 1997 Cadillac Catera

GM's Cadillac Division was having a tough time in the early 1990s, with an onslaught of Lexuses and Infinitis pouring across the Pacific to steal their younger customers while high-end German manufacturers picked off their older customers. Flying an S-Class-priced model between assembly lines in Turin and Hamtramck hadn't worked out, so why not look to the European outposts of the far-flung GM Empire for the next Cadillac? That's how the Catera was born, and I have found a rare first-year example in a North Carolina car graveyard. Across the Atlantic, GM's Opel and Vauxhall were doing good business with prosperous European car buyers by selling them the sleek rear-wheel-drive Omega B (whose platform also lived beneath the Holden VT Commodore in Australia). Here was a genuine German design that competed with success against BMW and Audi on their home turf! So, the Omega B was Americanized and renamed the Catera. Opel wasn't a completely unknown brand to Americans at the time, since its cars were sold here with their own badging through Buick dealerships from the middle 1950s through the late 1970s (for a much shorter period, American Pontiac dealers attempted to sell Vauxhalls). Even after that, plenty of Opel DNA showed up in the products of U.S.-market GM divisions. The Catera was by far the most affordable Cadillac for 1997, with an MSRP starting at $29,995 (about $59,113 in 2024 dollars). Being a genuine German car, it looked much more convincingly European than the DeVille ($36,995), Eldorado ($37,995) and Seville ($39,995). Inspired by the ducks on the Cadillac emblem (they were really supposed to be martlets, mythical birds with no feet and occasionally lacking beaks), Cadillac's marketers went after youthful car shoppers with a whimsical animated duck named Ziggy. For the 21st century, the birds were removed from the Cadillac emblem in order to attract California buyers under 45 years of age. As we all know, the Catera flopped hard in the marketplace. What sold well in Europe turned out not to translate so well in in North America, especially when bearing the badges of such a historically prestigious brand. The Catera's engine was a 54-degree 3.0-liter V6 rated at 200 horsepower and 192 pound-feet. Just as had been the case with its predecessor, the Allante, no manual transmission was available.
