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.

We really want to use an eCrate to restomod an old GM car. Here's what we'd build

You hopefully saw the news today of GM's introduction of its Connect and Cruise eCrate motor and battery package, which effectively makes the Bolt's electric motor, battery pack and myriad other elements available to, ah, bolt into a different vehicle. It's the same concept as installing a gasoline-powered crate motor into a classic car, but with electricity and stuff.  This, of course, got us thinking about what we'd stuff the eCrate into. Before we got too ahead of ourselves, however, we discovered that the eCrate battery pack is literally the Bolt EV pack in not only capacity but size and shape. In other words, you need to have enough space in the vehicle to place and/or stuff roughly 60% of a Chevy Bolt's length. It's not a big car, but that's still an awful lot of real estate. There's a reason GM chose to simply plop the pack into the bed and cargo area of old full-size SUVs. Well that, and having a rear suspension beefy enough to handle about 1,000 pounds of batteries.  So after that buzz kill, we still wanted to peruse the GM back catalog for classics we'd love to see transformed into an electric restomod that might be able to swallow all that battery ... maybe ... possibly ... whatever, saws and blow torches exist for a reason.  1971 Buick Riviera Consumer Editor Jeremy Korzeniewski: If you’re going to build an electric conversion, why not do it with style? ThatÂ’s why IÂ’m choosing a 1971-1973 Buick Riviera. You know, the one with the big glass boat-tail rear end that ends in a pointy V. Being a rather large vehicle with a big sloping fastback shape, IÂ’m hoping thereÂ’s enough room in the trunk and back seat to pack in the requisite battery pack. That would likely require cutting away some of the metal bulkhead that supports the rear seatback, but not so much that a wee bit of structural bracing couldnÂ’t shore things up. The big 455-cubic-inch Buick V8 up front will obviously have to go. Remember, this was the 1970s, so despite all that displacement, the Riviera only had around 250 horsepower (depending on the year and the trim level). So the electric motorÂ’s 200 horsepower and 266 pound-feet of torque ought to work as an acceptable replacement.   1982 Chevrolet S10 Associate Editor Byron Hurd: OK, so the name "E-10" is already taken by a completely different truck, but let's not let labels get in the way of a fun idea.

GM says EVs are the future — but trucks are going to take it there

In the PowerPoint deck for the General Motors Capital Markets Day presentation, one of the more disturbing things comes early on, during GM President Mark Reuss' initial remarks, in an area where he is discussing the company's overall strength in trucks. The point being made is that GM has a truck for all and sundry. And there it is, a phrase on a slide that should send chills up the spines of those who still pine for the old Bob Seger "Like a Rock" Silverado ads: "Little bit country. Little bit rock 'n' roll." That's right. Donny and Marie. Somehow the Denis Leary snark in the F-150 ads is all the more appealing. The Capital Markets Day presentation was chock full of observations about electrification and automation (Reuss and CEO Mary Barra both noted that the corporation's vision is one of "Zero Crashes. Zero Emissions. Zero Congestion." Dan Ammann talked about the progress being made at Cruise Automation; Reuss rolled out the plan for an array of electrified vehicles, with a luxury EV and a compact SUV being the "Centroid Entries" for the modular bases of many others). But it is worth noting that there is no getting away from the power of pickups in the U.S. market, as that was the central topic in Chief Financial Officer Dhivya Suryadevara's comments, with "Truck Franchise" being flanked by "Key Financial Priorities" and "Financial Outlook." Clearly, to gloss the old phrase, the truck segment is where the money is. Suryadevra enumerated how the truck segment is significantly different than other types of light vehicles. Among her points: GM, Ford and FCA have more than 90% of market share. The truck parc has been growing and aging over the past 10 years. Customers are fiercely loyal to the segment—as in 70% of truck buyers are truck buyers. A good number of the vehicles are for commercial use (40 percent). Trucks are "less prone to. . .mobility disruption." Trucks offer high margins. Translaton: The segment is one that they're solidly positioned in. There are lots of old trucks on the road that will need to be replaced by new ones. Perhaps buyers may switch from a Sierra to a Canyon, but it will be a truck. If your livelihood depends on that type of vehicle, even if gas prices go up or the economy begins to go south, you're going to stick with it. Most of the country isn't San Francisco, so trucks will continue to be essential. And, well, they're profitable in the extreme.
