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 ELR production has stopped, Chevy Bolt coming in Oct.

It looks like General Motors' Cadillac ELR extended-range plug-in is out as the automaker prepares to go all in on the Chevrolet Bolt electric vehicle. The Caddy officially stopped production in February, Hybrid Cars says, citing Cadillac Product Communications Manager David Caldwell. There is still a "small quantity" of the coupe at dealerships, but this take on mashing up "luxury coupe" with "green vehicle" has about run its course. Caldwell and Johan de Nysschen, president of General Motors' Cadillac division, had already confirmed earlier this year that the ELR, which was first available as a 2014 model, wouldn't have any further generations, though weren't specific on when production would stop. The ELR uses an upgraded version of the first-generation Volt's powertrain to move the 4,000-pound beast, and while the Volt is now in its second generation (and this year's sales have more than doubled from a year earlier as a result), the ELR never received a similar upgrade. The ELR sold just 357 units through April. As a result, the ELR sold just 357 units through April, down almost nine percent from a year earlier. In all of last year, 1,024 ELRs were sold, compared to more than 15,000 units for the Chevy Volt, and that's after the ELR's price was cut by about $9,000 last April. The car also got about a 25-percent increase in power, but that didn't seem to do the trick when it came to boosting demand, even with the available $7,500 federal tax credit. Meanwhile, Hybrid Cars is reporting that the 2017 Bolt, which will feature a single-charge range of about 200 miles and is expected to retail for about $35,000, is likely to start production at GM's Orion Assembly Plant in October. While you wait, if you're already feeling nostalgic, check out our impressions of the ELR here.

GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.
