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.

2023 Cadillac Lyriq vs Tesla Model Y, Audi E-Tron, Jaguar I-Pace | Specs compared

The 2023 Cadillac Lyriq is the latest electric luxury crossover to enter a quickly growing segment. It brings with it the company's trademark creased design language along with high-tech features and an impressive amount of range. The Cadillac also happens to have a price and specifications that put it square in the middle of a competitive group, so we had to line up the numbers to see how it compares. We've gathered up a selection of premium electric crossovers including the Tesla Model Y, Audi E-Tron and Jaguar I-Pace, all of which seem like the closest rivals for the Cadillac. We've assembled all the raw numbers in the chart below. We've also got some additional analysis below that. And now, onto the data. Power, range, efficiency Interestingly, the Cadillac is the least powerful of the bunch. This is a bit surprising considering that GM will have a 1,000-horsepower electric Hummer pickup coming out soon. But in the Lyriq, Cadillac only uses a single electric motor powering the rear wheels. While its 340 horsepower and 325 pound-feet of torque should be more than adequate, it falls short of all the dual-motor, all-wheel-drive competition. Because Tesla does not provide horsepower or torque numbers, we're not sure how much the base model makes. We assume it's close. The true power fiends will likely want the optionally available Model Y Performance, though. It also doesn't have publicized power numbers, but its 0-60 mph time of 3.5 seconds suggests its substantially more powerful than the other crossovers, here. Power is all well and good, but range is arguably more important for an electric car. The Tesla is on top, here. The base Long Range trim has an estimated range of 326 miles. The company doesn't specifically say how large the battery is for it or the Performance, which goes 303 miles. The Cadillac is close behind with a current estimate of more than 300 miles on its 100-kWh battery. Cadillac doesn't say whether that number is the gross amount or the usable amount. The Audi and Jaguar lag behind with less than 250 miles from their 95- and 90-kWh batteries, respectively. Audi is the only company that notes that the usable capacity is less than the total, which is a common strategy employed to extend the life of the battery and to maintain consistent ranges over time. 2020 Audi E-Tron View 13 Photos While not as broadly discussed as range, we also wanted to touch on efficiency.

Cadillac will build a Tesla fighter, sources say, as GM's leading EV brand

WASHINGTON — Cadillac is expected to become General Motors' lead electric vehicle brand as the largest U.S. automaker gears up to introduce a new model under that luxury marquee to challenge Tesla, two people briefed on the matter said Thursday. GM is set to announce Friday as part of an investor update that a Cadillac will be the first vehicle based on its forthcoming "BEV3" platform, the people said. The vehicle platform is the basis for vehicle underpinnings, including the battery system and other structural and mechanical parts. GM is not expected to disclose on Friday additional details, including precisely when the Cadillac EV will be built, whether it will be a crossover or sedan, or where it will be assembled, the sources said. A GM spokesman declined to comment. GM had previously focused on making electric vehicles under its mass market Chevrolet brand, including its plug-in Chevrolet Volt and battery electric Bolt. GM announced last year it was ending production of the plug-in Volt as well as a low-selling plug-in Cadillac CT6, even as it moved to boost EV spending. GM said in November as part of its restructuring efforts it was doubling resources for electric and autonomous vehicle programs over the next two years. Last month, two Ohio senators asked GM to commit to building all future electric vehicles for U.S. buyers within the country. GM said in 2017 it planned by 2021 to introduce a new dedicated flexible electric vehicle architecture and an advanced battery system to support the development of at least 20 new models in the United States and China. GM said in 2017 that a new electric vehicle platform in 2021 will serve as a base for at least nine derivatives, ranging from a compact crossover to a large seven-passenger luxury sports utility vehicle and a large commercial van. Johan de Nysschen, who was then Cadillac's president, told Reuters at the Detroit Auto Show in January 2018 the luxury brand will play a "central role" in GM's electrification strategy, including China. He added that Cadillac would be "at the forefront" of rolling out new electric vehicles in the United States and China. He left GM in April. This week, GM said Cadillac sales in China rose 17.2 percent in 2018, surpassing 200,000 units for the first time. GM Chief Executive Mary Barra has said that GM aims to sell 1 million electric vehicles a year by 2026, many of them in China, which has set strict production quotas on such vehicles.
