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.

About 150 Cadillac dealers would rather leave the brand than sell EVs

Dealerships might hamper GM’s plans to electrify its cars. Wall Street Journal tipsters claim that roughly 150 GM dealerships in the United States have decided to drop the Cadillac brand and accept a buyout (ranging from $300,000 to over $1 million) rather than spend about $200,000 to upgrade the dealerships with charging stations, repair hardware and other equipment needed to sell EVs. Many of these dealerships only sell a few Cadillacs per month versus more for Buick, Chevrolet and GMC, but itÂ’s still a significant blow when GM has 880 Cadillac dealers in the country. Cadillac brand leader Rory Harvey confirmed to the WSJ that GM was offering buyouts, but didnÂ’t say how many dealers took them or how much they were worth. The exodus underscores the challenges for conventional car brands as well as the potential advantages for alternatives like Tesla. As brands like GM are heavily dependent on dealerships, they have to please owners to have a chance of strong sales — and thatÂ’s difficult when theyÂ’re not certain about demand, even without the pandemic. Tesla and other direct-to-customer EV makers arenÂ’t bound by physical stores and already have the infrastructure in place for service centers. Dealers might not have much choice in the future. California is banning sales of new gas-powered cars by 2035, and that will likely force automakers to electrify no matter how dealership owners feel. The buyouts now arenÂ’t necessarily temporary, but we wouldnÂ’t rule out some shops having a change of heart as the effective EV deadline approaches. Related video:
