Junkyard Gem: 1976 Cadillac Eldorado Convertible

Convertibles rode high well in 1960s America, with Detroit selling more than 500,000 ragtops in 1965, but sales collapsed by the early 1970s and tightening federal crash-safety regulations made it seem less worthwhile to even bother producing new ones. Chrysler halted convertible production after 1971, with Ford following suit by 1973. By the 1976 model year, the Cadillac Eldorado was the last new American car you could buy with a convertible top from the factory, and it appeared that none would ever be built again. I've found one of those "last convertible" Eldorados in rough-but-identifiable condition in a Denver junkyard. As it turned out, the convertible never really died in America. Car shoppers could still buy new European-made convertibles after 1976, coachbuilders modified new Detroit cars with factory-grade drop-tops, and then Chrysler began selling K-Car convertibles starting with the 1982 model year. Because the '76 Eldorado appeared to be the absolute end of the convertible line, however, buyers thought they were investing in a sure-fire collector car that would be worth vast sums in the not-very-distant future (this belief led to lawsuits against GM later on, when the Cadillac Division resumed production of the Eldorado convertible for 1984). While a one-of-200-made Bicentennial Edition Eldorado with red-white-and-blue trim really is worth plenty these days, an ordinary 1976 Eldorado in beat-up condition doesn't seem worth restoring. This car appears to have sat outside in Colorado with the top down for decades, filling with snow each winter and enduring high-elevation solar irradiation each summer. A 1960s GTO or Camaro might be worth fixing up after falling into this state of disrepair, but not one of 14,000 "last convertible" Eldorados made in 1976. GM's Unified Powerplant Package front-wheel-drive system, which used battleship-strength chains to transmit power to the drive wheels, proved to be extremely reliable on the street, joining the small-block Chevrolet engine and Hydra-Matic transmission in the pantheon of The General's Greatest Engineering Hits. Even gigantic motorhomes used this system. In 1976, the Eldorado got the last of the 500-cubic-inch (8.2 liter, or litre as GM's marketers spelled it) V8s, rated at a disappointing 190 horsepower and an impressive 360 lb-ft of torque.

Cadillac's semi-autonomous Super Cruise pushed back to 2017

It looks like General Motors is discovering just how difficult it is to bring autonomous vehicle technology fit for public consumption to market. The company has pushed back the launch of its semi-autonomous Super Cruise technology by several months. Originally promised by CEO Mary Barra for a fall 2016 debut, Super Cruise was supposed to be offered first on the new CT6 sedan. Automotive News is reporting that won't be the case, following a statement from GM confirming that the new system would be pushed to sometime in 2017. At the very least, that's a several month delay. GM cited the need to get the system right and keep owners safe, which prevented a firm date for Super Cruise's debut. Product boss Mark Reuss was more blunt, though, telling AN, "It will come out when it is ready." Super Cruise would be one of the earliest examples of driverless tech to be put into public hands, following the introduction of Tesla's semi-autonomous AutoPilot system in 2015. Most other automakers experimenting with the autonomous vehicles don't foresee public sales until early in the next decade, including Toyota, Renault-Nissan, and Volvo. Before Barra suggested a 2016 debut, GM originally aimed to introduce its semi-autonomous system in 2020. Related Video:

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:
