GM Super Cruise beats Tesla Autopilot again in latest hands-free test

DETROIT — General Motors' Super Cruise once again edged Tesla's Autopilot in an evaluation of 17 vehicles equipped with active driving assistance systems (ADAS) by Consumer Reports, the testing organization said on Wednesday. A Tesla Model Y fitted with Autopilot finished "a distant second," the group said, to a Cadillac CT6 equipped with Super Cruise, which GM is rolling out to more than 20 vehicles — including its new Hummer electric pickup truck — over the next three years. Safety and insurance researchers have frequently warned of the risks of consumers overestimating ADAS systems' abilities, a misconception increased by some automakers calling their products Autopilot, ProPilot or Co-Pilot. In 2018, the Cadillac CT6 with Super Cruise scored higher than a Tesla Model 3 with Autopilot, in a Consumer Reports test of just four vehicles equipped with ADAS. In the latest test, conducted this summer on a track and on public roads, the Cadillac scored 69 points out of a possible 100, while the Tesla scored 57. A Lincoln Corsair equipped with Ford's Co-Pilot 360 system, finished third with 52. The critical difference in the Super Cruise system is a driver-facing infrared camera to make sure he or she is paying attention to the road and is ready to take over manual control when necessary, said Kelly Funkhouser, head of connected and automated vehicle testing at Consumer Reports. The group noted that Autopilot can shut off abruptly in some situations, while Super Cruise did a better job of notifying the driver when the system is disengaging. In recent European safety testing, a Tesla Model 3 with Autopilot placed sixth out of 10 systems, getting high marks for performance and ability to respond to emergencies, but falling short on its ability to maintain a driverÂ’s focus on the road.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

GM reworking mandatory OnStar plans for some 2024 models

For the 2023 model year, GM added its OnStar and Connected Services plan as standard equipment to a large number of Buick, GMC, and Chevrolet vehicles. Folding the $1,500 retail price into the MSRPs of models like the GMC Acadia and Buick Encore plumped up prices beyond the usual year-on-year bumps. Looks like there's a reversal in play for 2024, GM Authority reporting that many of the models fitted with OnStar and Connected Services — now called OnStar Premium — will step down to three years of OnStar Remote Access standard.   OnStar Remote Access comes with these features: Remote key fob, vehicle locate, and remote personalization through mobile and in-vehicle apps. Three additional features can be added to the plan: OnStar Guardian, in-vehicle hotspot, and Super Cruise. Owners can also upgrade to OnStar Premium if they choose.  Higher trims like Buick's Avenir and GMC's Denali, plus the GMC Hummer and the Cadillac Escalade will retain OnStar Premium as standard equipment. That suite starts with Remote Access and adds: Automatic crash response, stolen vehicle assistance and recovery, OnStar Guardian, in-vehicle app access, unlimited streaming, three years of Super Cruise on vehicles with the hardware, and six months of SiriusXM radio. The Escalade puts a cherry on top with three years Sirius XM instead of six months. The Remote Access plan normally charges $14.99 per month. We're not sure yet if GM will subtract the cost of OnStar Premium from the MSRP and add the $540 for OnStar Remote Access, or if the trial period comes free of charge. Even if that's what happens, the change could take nearly $1,000 off the MSRP of a car like the GMC Acadia before any 2024 increases. We'll know more as the 2024MY models roll out and prices are announced. Related Video 2022 Buick Enclave Avenir revealed
