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.

2020 Cadillac XT5 light refresh shown in China ahead of U.S. reveal

We spied the lightly refreshed 2020 Cadillac XT5 not too long ago, but now we have official photos via China. Cadillac decided to reveal the mid-cycle refresh of its crossover on that side of the world, so the vehicle you're looking at here is a China-spec XT5. While this may be the case, many of the details unmasked about the vehicle will likely be seen here, too. Cadillac told us it will be able to confirm U.S. specifics in the near future. You may be wondering, what's different? Truthfully, there isn't much to the mid-cycle update from a visual perspective. The grille has been swapped for one that better matches all the other grilles in Cadillac's newest crossovers like the XT4 and XT6. Cadillac of China didn't include any photos of the rear for this light reveal. There are significant updates in other places, though. At least in China, Cadillac is giving the XT5 its new 2.0-liter turbocharged four-cylinder engine we first saw in the XT4. That engine produces a refined 237 horsepower and 258 pound-feet of torque. We can't say whether the crossover will or won't keep the 3.6-liter V6 option in the states, but adding the boosted motor won't come as a surprise. Along for the ride is GM's nine-speed automatic transmission that is paired to that four-cylinder. The interior looks largely the same, save for the addition of Cadillac's rotary knob to control the infotainment system. This follows suit with other newly-released Cadillacs that allow you to control the system with both the knob and the touchscreen. Another notable interior upgrade is the addition of the rearview mirror camera. Cadillac is clearly set on integrating this technology onto every car it makes, and we certainly don't have any qualms with that. One bit of tech that wouldn't be included for China but may present itself for the U.S. model is Super Cruise. We've been told to expect the driver assistance system to spread throughout the manufacturer's lineup, and the XT5 seems a perfect candidate for the tech. Watch out for more details and photos coming soon for the 2020 XT5, as Cadillac will be sharing more specifics on the U.S. version in due time.
