Hotter Cadillac CT5-V could use the CTS-V's 6.2-liter V8

Cadillac is in the final stages of testing the high-performance variant of the CT5, prototypes are racking up miles all over the world, and a recent report sheds light on the engine screaming between its punched-out fenders. It's a V8, to no one's surprise, but it's not the twin-turbocharged, 4.2-liter unit many believed the sedan would use. Sources familiar with Cadillac's product plan told Car & Driver the hotter CT5 — whose name hasn't been revealed yet — will receive an updated version of the supercharged 6.2-liter V8 that powered the mighty CTS-V. It developed 640 horsepower in the firm's last German-bashing super-sedan, though where engineers will peg the CT5's output remains to be seen. It will roast the rear tires through a paddle-shifted automatic transmission. The publication explained Cadillac chose the 6.2-liter because it's more compact than the 4.2-liter Blackwing engine it developed for the CT6. The former features a pushrod design, while the latter gets twin overhead cams that make it taller and wider. The CT5 is a new model, but its Alpha platform is older than Cadillac's newest V8. Cadillac hasn't announced what will power the flagship CT5. The model is tentatively due out in showrooms before the end of 2020, so we expect to learn more about it in the coming months. Seeing it in the metal for the first time during the 2020 Detroit Auto Show in June isn't entirely out of the question. What's next? If the report is accurate, the much-hyped Blackwing may end up being an orphan engine. It was developed specifically for the Cadillac brand, and inaugurated by the CT6-V that recently went out of production. The many rumors claiming General Motors will put the engine in other models to recoup its investment are falling like dominoes. It won't fit in the CT5, so there's no reason to believe it will end up in the smaller CT4; its flagship version will likely arrive with a twin-turbocharged, 3.6-liter V6 borrowed from the ATS-V. An earlier report claims the next-generation Escalade won't use the Blackwing, either, because making it fit would cost too much. Looking beyond Cadillac, the only General Motors-owned brand that could use the Blackwing is Chevrolet, since we can't imagine the GMC Yukon will get it if the Escalade doesn't. The Tahoe/Suburban duo is off the table, too.

Here's your chance to own a 7.0-liter V8-powered, stick-shifted Cadillac Catera

Cadillac never stuffed a V8 engine into the Catera, the entry-level model it sold in the United States from 1997 to 2001, so American tuner Lingenfelter stepped in and offered to perform the conversion. One of the few cars it dropped an eight-cylinder into is for sale, and the bigger engine is just one of many modifications performed on it. Listed on auction site Bring a Trailer, this 2001 Catera lost its V6 soon after it was leased to its first owner in Warren, Michigan. Lingenfelter replaced the 3.0-liter V6 with a 5.7-liter V8 and ditched the automatic transmission in favor of a six-speed manual, but that wasn't enough; the owner sent it back for more. It left the shop again with a custom-built, 7.0-liter V8 between its fenders. It's essentially a Chevrolet Corvette C5.R-based block topped with LS6 heads, an LS6 intake, and a less restrictive exhaust. Its horsepower and torque outputs aren't available, unfortunately, but we assume the V8 easily doubles the stock Catera's 200-horse output. Cadillac marketed the Opel-built Catera as the Caddy that zigs, not as the Caddy that humiliates hot rods on a drag strip, so additional modifications were required to keep the V8's power in check. Highlights include a limited-slip differential, a lowered suspension with bigger sway bars, and beefier brakes all around. At one point in its life, this Catera also received 17-inch alloy wheels, a three-spoke steering wheel, and a sprinkling of V emblems. Although engine swaps are often hit or miss, this Catera has spent approximately 18 years and 40,000 miles with a V8 under its hood, so it's apparently a solid, well-thought-out build. It currently has 42,000 miles on its odometer, and it's located in Michigan. Bidding stands at $6,250 as of this writing, with five days left in the auction. It won't stay in the four-digit range for long, and it might end up costing as much as a late-model ATS-V, but when are you going to find another one like it?
