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.

2021 Cadillac Escalade's EPA highway fuel economy is worse than before

EPA fuel economy estimates for the 2021 Cadillac Escalade are out, and the news is mostly not good. The redesigned SUV sees slim to no improvement in the Feds' city ratings, and its highway numbers are considerably worse than before. These are estimates for the standard 6.2-liter V8. Figures for the no-cost-optional 3.0-liter turbodiesel six have not been released yet. Specifically, the rear-wheel-drive 2021 Escalade has estimates of 15 mpg city, 20 mpg highway, and 17 mpg combined. Compared to the outgoing 2020 version, powered by the same 6.2L V8, those numbers represent a 1 mpg improvement in city (the lone piece of good news) but are 3 mpg worse on the highway. With all-wheel drive, the 2021 Escalade can't even get out of the teens, with EPA ratings of 14 mpg city, 19 mpg highway, and 16 mpg combined. That's the same city rating as before and a 2 mpg decline versus the 2020 model's highway rating. For further comparison, cross-town rival Lincoln's Navigator with its 3.5-liter turbo V6 manages 16 mpg city and 22 mpg highway (RWD) and 16/21 with AWD. No one expects an ultra-large, body-on-frame, three-row SUV to achieve Prius-like levels of fuel efficiency, but it's pretty rare these days to see such backsliding with a fresh redesign. Here's hoping the diesel variant will have a happier story to tell. Related Video:

Junkyard Gem: 1998 Cadillac Catera

A decade or so after Ford tried to swipe some US-market sales from European luxury marques by selling the German-built Ford Scorpio with Merkur badging, General Motors opted to sell the German-built Opel Omega luxury sedan as a Cadillac. The Catera was a reasonably nimble rear-wheel-drive sedan with a 200-horse DOHC V6 engine, and its badge-engineered nature made it a much less costly gamble than, say, the Cadillac Allante, which had its bodies built in Italy and flown to Michigan for assembly. Unfortunately, it had no manual transmission option, and Americans who remembered the miserable US-market Opels of the 1970s were put off by the Catera's Opelness. Its $29,995 list price was quite a bit cheaper than that of the (slightly less powerful) $39,800 BMW 528i and a bit less than the (slightly more powerful) $33,585 Acura 3.2 TL's cost, but the Catera didn't sell in large numbers. This one made it to a respectable mileage figure, and the nice interior shows that it was well-cared-for during its 18 years on the road. The ads for the Catera featured a cartoon duck named Ziggy. Fast, fun, fiendishly flexible! By 2000, Cadillac had ditched the duck and was touting the Catera's value. Related Video:
