Junkyard Gem: 1981 Cadillac Eldorado with V8-6-4 engine

Skyrocketing fuel prices caused by geopolitical events in 1973 and 1979 led to gas lines, federal fuel economy requirements, and an increasing reluctance on the part of American car shoppers to buy big, thirsty Detroit luxury machines. General Motors had pulled off some amazing technological feats in the past — the small-block Chevrolet V8 engine and Hydramatic transmission being two extraordinarily successful ones — and so Cadillac's bosses figured that a combination of computer wizardry and clever mechanical engineering would give the 368-cubic-inch Cadillac V8 a cylinder-deactivation system and resulting superior fuel economy. Here's a very rare example of one of those 1981 Cadillacs, found in a California self-service wrecking yard. The idea behind the V8-6-4 was that computer-controlled solenoids would physically disengage the rocker arms for one or two cylinders on each engine bank under low-load conditions, converting the engine from a 368-cube V8 to a 276ci V6 or 184ci V4 (that's 6.0, 4.5 or 3.0 liters, respectively, for the metric-system aficionados among us). This sort of variable-displacement magic is commonplace today, but it was science-fiction stuff in 1981. An "MPG Sentinel" display on the dash would let the driver know how many cylinders were active at the moment, and the car would get Chevy Citation fuel economy with Cadillac luxury. The V8-6-4 was the standard engine in all 1981 Cadillacs (except for the Seville, which had the troubled Oldsmobile diesel engine as the base powerplant and the V8-6-4 as an option). Unfortunately, the V8-6-4 worked about as well as the Oldsmobile diesel: very poorly. Within a few years, most owners of these engines had disconnected the rocker-deactivation solenoids and just drove their cars as regular full-time V8s. This one has the snazzy "Cabriolet Roof Treatment" option, which boasted "textured elk grain" vinyl and could be had in one of 17 available colors. Front-wheel drive gave the early-1980s Eldorado plenty of interior space, despite its more proletarian Olds Toronado origins, and these velour-covered seats made for very comfortable road trips. The price tag started at $17,550, or about $51,650 in 2019 dollars. The 1981 Imperial went for $18,311, and that car was based on the same platform as the lowly Plymouth Volare. Meanwhile, A BMW 733i cost $28,945 and a new Toyota Cressida a mere $11,599. The 1981 Cadillacs were just a little too much ahead of their time, it turned out.

2015 Cadillac ATS, CTS recalled over brake issue

A problem with the brakes on the 2015 ATS and CTS has prompted Cadillac to issue a recall. According to the notice below from the National Highway Traffic Safety Administration, the issue revolves around the bracket that connects the brake pedal assembly and the rod that actuates the brakes. Even under normal operation, that bracket could fracture, impeding the ability to slow or stop the vehicle. That, as you're surely aware, could increase the risk of a crash. The issue affects a reported 2,163 vehicles in the United States. Owners will need to be bring their vehicles in to their local dealership to have those brackets replaced starting on August 1. See the complete recall notice below. RECALL Subject : Brake Pedal Bracket may Fracture Report Receipt Date: JUN 09, 2015 NHTSA Campaign Number: 15V358000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 2,163 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Cadillac ATS and CTS vehicles. The affected vehicles have a bracket between the brake pedal assembly and the rod that actuates the brakes that may fracture during normal brake pedal operation. CONSEQUENCE: If the bracket fractures, the driver would not be able to apply the brakes, increasing the risk of a crash. REMEDY: GM will notify owners, and dealers will inspect the vehicle and replace any affected bracket, free of charge. The recall is expected to begin August 1, 2015.

Cadillac Super Cruise wins the 2019 Autoblog Technology of the Year Award

Autoblog's 2019 Technology of the Year winner is Cadillac's Super Cruise. The SAE Level 2 semi-autonomous system allows for hands-free highway driving, reducing driver fatigue and improving safety. Additionally, Super Cruise packs in safeguards that force a driver to stay alert, bringing in a level of accountability not found in other Level 2 systems. Cadillac beat out Infiniti's VC Turbo technology and the EQ Boost 48-volt system from Mercedes-Benz, the other two finalists. General Motors mapped more than 130,000 miles of highways across the country, so Super Cruise always knows where you are. A camera on the steering column keeps an eye on the driver to make sure they're watching the road. Stray your gaze too long and the system forces you to take back over. Super Cruise has its limitations — it won't change lanes for you — but it is the most well-rounded and refined semi-autonomous system we've ever tested. There's no ping-pong effect as the car finds the center of the lane, and it always seems to leave a comfortable gap between you and the car ahead. Super Cruise launched in the CT6, which is ending production this year. But the sophisticated technology will migrate to other Cadillacs in 2020. The system is as easy to use as any other adaptive cruise control. Indicators in the instrument cluster and a light on the steering wheel indicate when and if the system is able to work. If you're off the defined grid, you can still use the car's regular adaptive cruise control — you just have to keep your hands on the wheel. Autoblog editors were also impressed with Cadillac's responsible approach to marketing the tech. The company doesn't even promote it as a Level 2 system, as it doesn't want to over-promise and under-deliver. Quite the opposite actually. Super Cruise simply works, and it works well. That's why it's our 2019 Technology of the Year. We'll present the award next week at the Detroit Auto Show. Come back for video of the event. Related Video:
