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and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation.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.

Cadillac CT6 will get high-res streaming video rearview mirror

Cadillac is preparing a big upgrade to the humble rearview mirror, adding a streaming video function that it claims will improve a driver's field of vision by 300 percent. The new system will debut on the 2016 CT6 flagship. The streaming system, which eliminates the visual obstructions caused by passengers, headrests and the rear pillars, relies on a 1280-by-240-pixel TFT display and a high-definition camera to reduce glare and improve visibility in low-light conditions. That camera even addresses one of the big annoyances of today's camera systems, by adding a hydrophobic coating to keep the camera lens clear. The system can easily be switched off at the press of a button, at which point the driver has a simple electrochromatic mirror at his disposal. "The closest comparison to this kind of rear vision would be driving a convertible with the top down," Travis Hester, the CT6's executive chief engineer said in a statement. "The streaming video is a significant enhancement for the luxury customer interested in purposeful technology." Scroll down for the press release from Cadillac. Cadillac Adds Streaming Video to Enhance Driver Vision and Safety Display eliminates visual obstructions, increases rearward vision by 300 percent 2014-12-18 DETROIT – Cadillac late next year will add high-resolution streaming video to the function of a traditional rearview mirror, removing obstructions of passengers, headrests and the vehicle's roof and rear pillars. The streaming video mirror improves field of vision by an estimated 300 percent, or roughly four times greater than a standard rearview mirror. "The closest comparison to this kind of rear vision would be driving a convertible with the top down," said Travis Hester, Cadillac CT6 executive chief engineer. "In addition to the increased field of view, the technology eliminates any rear seat, rear pillar or passenger obstructions, allowing the driver an unimpeded view of the lanes behind and traditional blind-spots," Hester said. Thanks to a high dynamic range, the camera's video feed reduces glare and allows a crisper image in low-light situations, versus a traditional glass electrochromatic, or auto-dimming, rearview mirror. The in-mirror display is an industry-leading 1280 by 240-pixel TFT-LCD display with 171 pixels per inch, combined with a HD camera designed specifically to enhance rear view lane width and maximize low-light situations.

Cadillac recalls 17,500 SRX CUVs in Canada

When reporting on recalls, Autoblog generally tries to focus on the US market. However, a recent campaign in Canada seems important enough to be worth mentioning because it could eventually affect American drivers. General Motors is repairing 17,481 Canadian examples of the Cadillac SRX from the 2010-2015 model years because of the possibility of a loose nut in the rear suspension. For the moment, the automaker hasn't yet announced whether the CUV in the US would require a similar campaign.
The notice was dated September 18, 2014, on the website for Transport Canada, similar to the National Highway Traffic Safety Administration in the US. It says, "the rear suspension toe link jam nuts" might not have been sufficiency tightened, which could allow a rear wheel to turn "inboard or outboard" while driving. If this happens, it could cause a sudden change in handling. Canadian Cadillac dealers are inspecting the parts and replacing the toe link if necessary.
This campaign isn't listed on the GM's running recall tally from September, which includes exported models, but it does list four other campaigns for the SRX this year - three in this range of years and one for the 2004-2006 model. Autoblog reached out to the company to ask about the possibility of this recall expanding to the US and were told "We have not publicly announced US recalls" for the issues affecting the SRX. The New York Times was given a similar quote. Scroll down to read the notice from Transport Canada.
