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.

Buy a Mosler Twinstar, the V16 Cadillac you almost wanted [w/video]

Cadillac was once famous for opulent, V16 luxury vehicles, but this bizarre 16-cylinder 1999 Eldorado that's for auction on eBay Motors isn't much like its ancestors. Dubbed the TwinStar, this beast features a Northstar V8 with 275 horsepower to drive the front wheels and a second Northstar with 300 hp is in the trunk to spin the rear axle. Each mill has its own four-speed automatic gearbox, and the result is a total of 575 hp of all-wheel drive fury in an incredibly weird package. The TwinStar's interior and exterior certainly don't hide the odd powertrain setup. To fit the engine in the trunk, the builders pushed the rear wheels further back and lengthened the wheelbase. There are also scoops low on each side to funnel air to the V8. Inside, there's a second ignition on the side of the center stack, and a digital instrument cluster replaces the glove box. It's sure to confuse any passenger you can convince to take a ride in this thing. Mosler, the supercar company known for models like the MT900, built five TwinStars, according to the auction. The seller links to the original review by Car and Driver, and the magazine noted that the sensation of the two engines working in tandem was rather odd. However, the TwinStar was a capable performer and ran to 60 in 5 seconds in its test. If you want to start your new year with the oddest vehicle possible, the TwinStar's auction sits at $5,600 with the reserve not met as of this writing, and it ends January 2, 2016, at 8:00 PM ET. If you can't wait that long, the dealer lists the car online for $39,900. There's also a spirited conversation on Bring a Trailer about this automotive oddity.

Cadillac chief says ATS convertible, wagon on the table

What we do know is that the ATS will wear at least one more bodystyle. That comes from Cadillac head Bob Ferguson, who answered "Absolutely" when Automotive News asked him about the possibility of another variant. What we don't know is what that bodystyle or styles will be.
We now have a sedan and coupe ATS, there's supposedly a V sedan coming. After that, a convertible is a likely option given that the man who just became the global product honcho at General Motors, Mark Reuss, admitted to having one already designed in 2012. The decision on it can't get out of the underworld and a wagon is the other option, but the droptop would seem to make the most sense if one considers the competitive set: the BMW 4 Series and Audi A5 convertibles are hot property and Mercedes is bringing a C-Class convertible. Meanwhile wagons are the sentimental utility vehicles that, refusing to die, seem forever destined for life support... CTS Sport Wagon, anyone?
Based on Ferguson's statements, it appears that what Cadillac definitely won't do is play model variant catch-up with the European luxury brands it has spent years hunting down, telling Automotive News, "We want to keep our focus on a limited number of vehicles and do them very well."
