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 announces six new recalls, covering 3.5 million vehicles

General Motors has just initiated another crushingly large recall, this time affecting some 3.36 million vehicles built between 2000 and 2014 and sold in the US, Canada and Mexico. Once again, the issue surrounds the cars' ignition switches, which can be kicked out of the run position if they're carrying extra weight or if they experience a "jarring" event. In this particular case, though, GM will modify the keys, rather than the ignition itself.
A four-by-six-millimeter hole will be drilled into the key, which will more safely accommodate the weight of the key ring. As is usually the case, the work will be done free of charge. The recalled vehicles include the 2000 to 2005 Cadillac Deville, 2004 to 2005 Buick Regal LS and GS, 2004 to 2011 Cadillac DTS, 2005 to 2009 Buick Lacrosse, 2006 to 2008 Chevrolet Monte Carlo, 2006 to 2011 Buick Lucerne and 2006 to 2014 Chevrolet Impala. Only the Impala is still in production, and even then, it's only sold to fleet companies.
According to an official statement from GM, there have been eight crashes and six injuries due to this latest issue. As if this isn't a dire enough blow for GM, the company has announced five smaller recalls, covering 165,000 vehicles.

Here's your chance to own a 7.0-liter V8-powered, stick-shifted Cadillac Catera

Cadillac never stuffed a V8 engine into the Catera, the entry-level model it sold in the United States from 1997 to 2001, so American tuner Lingenfelter stepped in and offered to perform the conversion. One of the few cars it dropped an eight-cylinder into is for sale, and the bigger engine is just one of many modifications performed on it. Listed on auction site Bring a Trailer, this 2001 Catera lost its V6 soon after it was leased to its first owner in Warren, Michigan. Lingenfelter replaced the 3.0-liter V6 with a 5.7-liter V8 and ditched the automatic transmission in favor of a six-speed manual, but that wasn't enough; the owner sent it back for more. It left the shop again with a custom-built, 7.0-liter V8 between its fenders. It's essentially a Chevrolet Corvette C5.R-based block topped with LS6 heads, an LS6 intake, and a less restrictive exhaust. Its horsepower and torque outputs aren't available, unfortunately, but we assume the V8 easily doubles the stock Catera's 200-horse output. Cadillac marketed the Opel-built Catera as the Caddy that zigs, not as the Caddy that humiliates hot rods on a drag strip, so additional modifications were required to keep the V8's power in check. Highlights include a limited-slip differential, a lowered suspension with bigger sway bars, and beefier brakes all around. At one point in its life, this Catera also received 17-inch alloy wheels, a three-spoke steering wheel, and a sprinkling of V emblems. Although engine swaps are often hit or miss, this Catera has spent approximately 18 years and 40,000 miles with a V8 under its hood, so it's apparently a solid, well-thought-out build. It currently has 42,000 miles on its odometer, and it's located in Michigan. Bidding stands at $6,250 as of this writing, with five days left in the auction. It won't stay in the four-digit range for long, and it might end up costing as much as a late-model ATS-V, but when are you going to find another one like it?
