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 prepares to top its own 'Ring record with upcoming new CTS-V

It was a big deal back in 2008 when the original Cadillac CTS-V clocked a lap time of 7:59 at the Nürburgring, making it the fastest sedan ever to lap the Nordschleife to that date. Not many four-doors have bested that time since - the list consisting pretty much only of the Porsche Panamera Turbo - but now hot hatches are lapping faster than that, so you can bet that the new one will manage an even better time.
Now we've spotted the upcoming new CTS-based performance sedan several times before undergoing testing in locations around the world, but this is the first time we've seen it at the Nürburgring, apparently using the Goodyear Dunlop test facility as its base of operations (and still wearing Michigan manufacturer plates, incidentally). Considering how well the outgoing CTS-V performed and how much further you can bet Cadillac will push the envelop this time around, a new sedan lap record is almost a certainty - and we can only hope for an all-out war between Europe's performance sedan power houses to ensue.

Cadillac cancels its car subscription program after just two years

Cadillac is cancelling its Book by Cadillac subscription service, according to a report from the Wall Street Journal and confirmed to Autoblog by a Cadillac spokesperson. The $1,800 a month service has been in operation since early last year. The Cadillac spokesperson told us this: "Following nearly two years of service, Cadillac will temporarily pause the Book by Cadillac program effective December 1, 2018." This moves comes not too long after the decision to leave its New York City headquarters and return to Michigan. While Cadillac claims the disruption of service will be temporary, there's no defined plan to start the program back up again. The reason for the cancellation? The service ended up being more costly than Cadillac expected it to be. Owners will have 30 days from the time they're notified to turn their vehicles in. If this subscription service was your only transportation, then you better start looking for something else. The service was available in New York City, Dallas and Los Angeles. Subscribers could choose between five different Cadillacs: ATS-V, CTS-V, CT6, XT5 and Escalade. You'd be allowed up to 2,000 miles per month and 18 vehicle swaps per year through the concierge service. Cadillac would bring the car of your choice to you and take the old car away at your whimsy. The price included registration, taxes, insurance and maintenance costs. No long term commitment was necessary to sign up. This makes Cadillac one of the first manufacturers to end a nascent subscription service. If it starts back up again, expect it to look a bit different from the current program. Cadillac says it's using this experience to make strategy adjustments in the future. Whether that means a much more costly program for users, or no subscription program at all, we don't know. Plenty of other manufacturers still offer limited subscription programs in select cities. We highlighted some of the biggest ones in our vehicle subscription service guide here. It'll just be a waiting game to figure out if these modes of ownership take off going forward. For more information on Vehicle Subscription Services, check out the Complete Guide.
