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.

GM recalling 8.4M cars, 8.2M related to ignition problems

General Motors today announced a truly massive recall covering some 8.4 million vehicles in North America. Most significantly, 8.2 million examples of the affected vehicles are being called back due to "unintended ignition key rotation," though GM spokesperson Alan Adler tells Autoblog that this issue is not like the infamous Chevy Cobalt ignition switch fiasco.
For the sake of perspective, translated to US population, this total recall figure would equal a car for each resident of New Hampshire, Rhode Island, Montana, Delaware, South Dakota, Alaska, North Dakota, the District of Columbia, Vermont and Wyoming. Combined. Here's how it all breaks down:
7,610,862 vehicles in North America being recalled for unintended ignition key rotation. 6,805,679 are in the United States.

Hotter Cadillac CT5-V prototype spotted with a manual transmission

Fans of the old Cadillac CTS-V (and high-performance sedans in general) may have something to be excited about. A series of interior photos leaked Tuesday reveal that prototypes of the forthcoming higher-output variant of the CT5-V Sedan have been equipped with a manual gearbox. Exclusive: Photos show the wilder Cadillac CT5-V will have a manual transmissionhttps://t.co/Ta8hZ804eg — The Drive (@thedrive) March 10, 2020 Photos obtained by our friends at The Drive show a partially camouflaged CT5-V prototype with a full interior and what appears to be a manual gear selector. While the shifter and its boot are partially obscured by a plastic covering, it's obvious that the knob is not the same one paired with Cadillac's automatic gearboxes, such as the one featured in our expertly augmented photo above.  This is not the first time the potential for a stick-shift option in the new, higher-end "V" cars has been floated. Rumors suggesting that the as-yet-unnamed higher-output CT4-V and CT5-V models might be so-equipped (at least optionally) circulated late in 2019. This, in addition to significantly higher power outputs and revised suspensions will set them apart dramatically from the base CT4-V and CT5-V, which are intended to compete with the likes of the Audi "S" line of vehicles.  CT4-V spied View 40 Photos GM has been quite cagey when it comes to details about these new models. We know they'll follow in the footsteps of previous-generation "V" cars, which were aimed squarely at Europe's powerhouse sport sedans. The hotter CT5 variant is expected to employ the automaker's 6.2-liter supercharged V8, which made 640 horsepower in the now-dead CTS-V.  We reached out to Cadillac for comment and were told by a spokesperson, "The ultra-performance variants of our Cadillac CT5-V and CT4-Vs are still under development.  We will have more details to share in the next few weeks and the CT5-V and CT4-V ultra-performance versions will debut later this year. Until then, I can only confirm that these cars will build on V-SeriesÂ’ respected legacy." Hopefully, GM won't make us wait too much longer for official details of these new high-performance models, including what we should expect in terms of powertrain availability and launch timing.
