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.

Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.

General Motors could turn Hamtramck into its electric pickup, SUV hub

Electric off-roaders could revitalize the Detroit-Hamtramck factory that General Motors previously announced it will close. While official details remain shrouded in secrecy, analysts believe the plant will be re-tooled to manufacture at least three electric models due out during the early 2020s. The plant's scheduled closure was one of the grievances the United Auto Workers (UAW) union cited when it embarked on a 40-day strike in September 2019. General Motors agreed to keep it open without shedding much light on what it planned to build there. Analyst at LMC Automotive told the The Detroit News they believe an often-rumored electric SUV that will resurrect Hummer's name, image, or both will be one of the models assigned to the Hamtramck plant. Battery-powered variants of the GMC Sierra and the Cadillac Escalade will be made there, too, as will an enigmatic van. LMC Automotive's Jeff Schuster believes the van will come first; it could enter production as early as 2021. The Hummer — which might also be offered as a pickup — will follow before the end of 2022, while the Sierra and the Escalade will both arrive in 2023. We're taking this report with a grain of salt, though, because only one of the aforementioned models has been announced by General Motors. Rumors of a Hummer resurrection emerged in the summer of 2019, just a few weeks before we heard unverified reports of a battery-powered variant of the next-generation Escalade. General Motors confirmed plans to enter the burgeoning electric pickup truck segment, which Ford, Rivian, and Tesla also have their sights on, but it hasn't detailed how or when. The van is a mystery. General Motors refused to comment on the report. It previously announced it will keep Hamtramck open, and invest $3 billion to build electric vehicles there. The investment will create 2,225 jobs. Inaugurated in February 1985, the Hamtramck factory has churned out a diverse selection of models over the past 34 years, including Cadillac's Eldorado, Seville, and Allante, the Oldsmobile Toronado, the Buick Riviera, and more recently, gasoline-electric Chevrolet Volt. General Motors announced plans to close Hamtramck in 2018, but it quickly backpedaled and extended its lease on life until 2020 by keeping the Chevrolet Impala and the Cadillac CT6 around for a few additional months.
