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.

2016 Cadillac ATS-V brandishes 450 horses and 6-speed manual

Details about the hotly anticipated 2016 Cadillac ATS-V are tumbling out, and they look to be everything we could ask for in a high-performance Caddy coupe.
According to Road & Track, the ATS-V will use a version of the twin-turbocharged 3.6-liter V6 from the CTS Vsport, but the wick will be turned up to 450 horsepower and 445 pound-feet of torque. In glorious news for driving enthusiasts everywhere, that potent mill will be available with either a six-speed manual or eight-speed automatic.
According to R&T, the engine has a heap of high-performance tech to let it make the extra ponies, including titanium connecting rods, two water-to-air intercoolers, titanium turbines for the turbos and an additional radiator dedicated to cooling the gearbox and electronically locking differential. Keeping it all planted are a set of Michelin Pilot Super Sport tires, and a suspension with 50 percent more roll stiffness.

Cadillac CTS-V, ATS-V special editions celebrate IMSA titles

This was Cadillac's first year of competition for its DPi-V.R. Daytona Prototype race car in the IMSA Endurance Championship, and it brought home both the manufacturer title and driver title. To celebrate the occasion, Cadillac has created special editions of its fastest road cars, the CTS-V and ATS-V, and their defining features are stickers. Yes, the most unique part of these special Cadillacs is a decal package. But it is an attractive one, with white, gray, silver and red accents inspired by the race car. They're complemented by either a black or white paint job and red side mirrors. The rear quarter windows also get little stickers of the race car's silhouette. Though the stickers are the defining trait of these special-edition cars, they aren't the only features. The CTS-V and ATS-V each come bundled with an array of other features such as a sunroof, the carbon fiber exterior accent package, and a red and black interior that features red-accented carbon fiber trim and Recaro seats. Available as additional options are an eight-speed automatic for the ATS-V, a performance data recorder and a suede steering wheel and shift knob. The other neat tidbit is that, if those extra features are must-haves, the IMSA edition ATS-V is the way to go. The $72,190 price for the sedan is almost $2,000 less than an equivalent standard ATS-V sedan. The regular ATS-V sedan also isn't available with the red and black interior. The special-edition ATS-V coupe starts at $74,390, which is a little over $1,000 more than an equivalent normal ATS-V coupe. Unfortunately for CTS-V buyers, the IMSA edition model, at $105,730, is pricier than optioning up a regular CTS-V. So in that case, you'll have to decide whether the decals and exclusivity are worth it.
