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.

Combine a self-driving car with V2V, and here's what happens

Transportation engineers have started laying the groundwork for a traffic world in which cars communicate with other cars and infrastructure like bridges and traffic lights. How about an environment in which cars talk to pretty much everything and everyone? In a preview of its offerings at the upcoming Consumer Electronics Show, Delphi Automotive will deploy just such a concept. Engineers have designed a system that communicates with traffic signals, street signs, pedestrians, cyclists, even to fry pits and parking garages along a driver's route. To date, engineers and researchers across the auto industry have focused on the technical and safety-oriented foundation of future vehicle-to-vehicle communications, which could help cars share information about everything from traffic tie-ups to upcoming road hazards. Beyond those building blocks, many have projected that V2V could also include more consumer-focused features. Delphi's system, dubbed V2Everything, might be the first that combines those sorts of features in a tangible package. At CES in Las Vegas, scheduled to begin the first week of January, company officials say they'll demonstrate in real-world conditions how V2V technology can be used in an autonomous vehicle to provide a range of critical safety information and leisure and convenience options for riders. The first V2V technology installed on a production car is slated to appear on the 2017 Cadillac CTS. "We imagine a world with zero traffic accidents," said Jeff Owens, Delphi's chief technology officer. "To get there, we will need a convergence of active safety, sensor fusion, connectivity platforms and advanced software." Such software might allow a vehicle to start searching for and reserving parking spots at a programmed destination long before arriving. It could allow riders to place their McDonald's drive-through order from the road and have the food ready for pickup along the route. For the drive itself, the Delphi-equipped car can stay updated on the status of traffic lights around Las Vegas, and can anticipate yellow and red lights. Using smart-phone technology, the car can detect pedestrians and cyclists that may otherwise be hard to see. It can send messages to friends or family to notify them of a driver's location. Some of those features have been available on third-party apps or individually developed by automakers. But this system marries them together in a single system that is tailored for use in self-driving cars.

2019 Cadillac XT4 vs. other compact luxury crossovers: How they compare

After years of every other luxury car maker stocking their showrooms with trendy crossovers, Cadillac is finally joining the fray. Its latest addition is the 2019 Cadillac XT4, a tidy little crossover that proudly bears signature Caddy designs such as the tall slender taillights. And based on our first drive of the car, it impresses in many ways, such as its refined engine, classy interior and excellent ride quality. View 39 Photos That's good news for the little Cadillac, but it needs to stand out in a big segment. To see if it has any other areas where it shines, or maybe some where it's a bit dim, we decided to compare its specifications with those of four of the segment's bestselling compact crossovers, the Lexus NX 300, Acura RDX, Audi Q5 and BMW X3. And for good measure, we threw in the XT4's crosstown rival, the Lincoln MKC. View 15 Photos Here's a chart showing each of these vehicles' vital stats, including horsepower, torque, fuel economy, cargo space, passenger space and price. Further analysis follows. If you'd like to compare any of these vehicles with other luxury crossovers, be sure to check out Autoblog's Car Finder and Compare tools.

And don't be afraid to check these cars out in person at their respective dealerships. Engines, transmissions and fuel economy With the exception of the Lincoln MKC's optional 2.3-liter engine, every competitor here resorts to the same type of engine, a turbocharged 2.0-liter four-cylinder, for its propulsion. And unsurprisingly, they make similar power, in the mid-200 horsepower and mid-200 lb-ft of torque range. Of the 2.0-liter engines, the standout is the Acura RDX, which produces a hearty 272 horsepower and 280 pound-feet of torque. It's second in power only to the Lincoln's optional turbo 2.3, which makes 285 horsepower and 305 pound-feet of torque. The bottom of the pack is the Lexus with 235 horsepower and 258 pound-feet of torque, but the next least powerful crossover is the Cadillac XT4, with just two more ponies than the Lexus, and the same amount of torque. View 22 Photos Though the Cadillac is nearly the least powerful, it does get to claim the best fuel economy numbers, rated at 24 mpg in the city, 30 on the highway, and 26 combined with front-wheel drive.
