Cadillac Super Cruise gets system enhancements, more compatible highways

Cadillac is updating Super Cruise to make it available to use on more highways, and it will offer better performance, too. Previously, Super Cruise worked on about 130,000 miles of highways across the continent. This update expands that to 200,000 miles. That's because GM has mapped that many more miles to be compatible with its lidar mapping system. As for the performance update, Cadillac says there will be enhancements to the driver monitoring system. That's the key feature that separates Super Cruise from all the other systems out there, making it a truly hands-free experience. It's able to quickly tell whether your eyes are on the road, and it reacts accordingly. We asked for details about the improvements, but all Cadillac would tell us is that there are "slight refinements to the driver attention system to even more accurately detect driver attention." Perhaps it's related to reports of sun-related issues plaguing the infrared monitoring camera. We can't tell you for sure. As for the extra miles, Cadillac says some added highways now include limited intersections and traffic control devices. Basically, there may be a stoplight or some cross traffic thrown into the mix now. Since GM has actually gone and mapped these areas, the car will tell you to take back control when approaching a railroad crossing, pedestrian crossing, stoplight or stop sign. Cadillac included a map (above) depicting the original and new Super Cruise compatible highways. You'll notice there are a lot more highways in the midwest and southeast, in addition to almost being able to cross the entirety of Canada now. Things are still a bit sparse in the western part of the country, but there aren't as many highways out there anyway. Owners of 2018 and 2019 Cadillac CT6s can expect to get the upgrade, but it's not as easy as you may think. Folks will have to take their CT6 in to the Cadillac dealer, where the "system enhancement" will take place. However, that enhancement doesn't include the additional miles. Cadillac says that update will be sent out over-the-air throughout the summer and fall. Updates for Super Cruise seem to be coming out with regularity. Last year Cadillac updated the system for easier activation, better lane placement (for passing large vehicles) and added gauge cluster messages for more information. We happen to love using the technology here at Autoblog, and gave it our 2019 Technology of the Year award.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

2021 Cadillac XT6 adds 2.0-liter turbo and new base trim in second year

The 2021 Cadillac XT6 has been announced, and the three-row crossover is going through a few notable changes in its second model year. There’s a new base trim and base engine, and Cadillac has added tech features to improve the experience. Starting with the new engine: ItÂ’s the 2.0-liter turbocharged four-cylinder that was initially introduced in the XT4 as the base motor. Power output is the same as the compact crossover at 237 horsepower and 258 pound-feet of torque. ItÂ’s paired with the nine-speed automatic transmission and comes with front-wheel drive as standard — all-wheel drive is a $2,000 option. That engine only comes with the new base trim level: Luxury. Every other trim receives the 3.6-liter V6. The new Luxury trim (pictured above) is being added to the lineup as a base model to compliment the Sport and Premium Luxury trims. This will be the cheapest and most basic of the XT6s, but you can still option all-wheel drive. Features include 18-inch wheels, the eight-inch touchscreen infotainment system, black leatherette seats (heated and powered in front), brushed aluminum trim, tri-zone climate control and a number of other smaller extras along with a suite of driver assistance technologies. Cadillac is also adding wireless Apple CarPlay and wireless Android Auto to the lineup as standard equipment — they were standard previously but required the traditional wired connection. ThereÂ’s also a new 20-inch wheel for the Sport model, and three new color options: Dark Moon Blue Metallic, Wilder and Infrared Tintcoat. The XT6 LuxuryÂ’s base price is $48,990, including the destination charge. ThatÂ’s a fair cut below the 2021 Premium Luxury ($53,790) and the Sport ($58,190) trims, but you are losing out on the additional equipment and luxury those trims offer. Cadillac says the updated 2021 XT6 will land in dealerships this fall. Related video:
