Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Junkyard Gem: 1967 Cadillac Fleetwood Sixty Special Sedan

If you lived in North America in 1967 and you wanted to show the neighbors you'd clawed your way to the peak of the success pyramid, only one car would do: Cadillac Fleetwood. Today's Junkyard Gem is 4,685 pounds of General Motors luxury hardware, finally knocked off the road at age 53 by an unfortunate wreck and now residing in a Denver self-service wrecking yard. The Cadillac brand endured some rough years during the 1970s and 1980s, but rode high during the 1960s. The Fleetwood Sixty Special Sedan started at $6,423 in 1967, or just over $50,000 when figured using inflation-adjusted 2020 dollars. A Mercedes-Benz 250SE sedan set you back $6,385 that year, but it weighed barely half as much and packed just 148 horses against the Cad's 340. Really, you had to get a genuine Rolls-Royce to out-swank the Fleetwood-driving Joneses back then (the Lincoln Continental and Imperial didn't have quite the snob appeal at that time), and the Roller cost more than several Fleetwoods combined. This car has been around during its long life. On the windshield, we see 1980 and 1981 parking stickers from the Keeneland Club in Kentucky. This car was already 13 years old by that time, but still very classy. At some point, the car must have migrated to California. Here's a U.C. Berkeley sticker. This ancient In-N-Out sticker comes from the Southern California-only era of the famous hamburger chain. Sometimes it's tough to determine the reasons that an old car ended up in a place like this, but that's not a problem here. Let's hope the car's occupants had their belts on (lap belts only in 1967, but still better than nothing), because these old Detroit land yachts didn't have much in the way of energy-absorbing crumple zones. The paint and interior are quite rough, so this car depreciated from being worth perhaps a couple of grand to scrap value in an instant.  Cruise control was a very rare option in 1967, and this car has it. The famous Fleetwood triple-tone horns were still there when I got to this car. Under the hood, 429 cubic inches (7.0 liters) of super-smooth Cadillac pushrod V8. This engine grew to 472 and then 500 cubic inches during the following few years. The paint shows some great patina. Did I buy the horns? Of course I bought the horns — I always bring my trusty lightweight junkyard toolbox when I head out to shoot some Junkyard Gems. Related Video:
