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.

The Beast 2.0: What the 2016 presidential election winner will ride in

The current presidential limousine, which is referred to as "The Beast," will be altered for the next President of the United States. Our photographers managed to capture the vehicle testing. " The Beast 2.0" will follow closely behind the current presidential limousine that's built upon a rugged commercial truck chassis and has a sedan-like body. Instead of wearing styling details from the now-retired Cadillac STS, the new presidential limo appears to borrow looks from the latest Escalade and the CT6 sedan. The bomb-proof prototype is wearing LED headlights, has a more angular grille that features Cadillac's wreathless crest, and ditches regular antennas for a shark fin unit. Other than these changes, the Beast 2.0 should still be able to house seven passengers and have enough protection to be one of the safest vehicles on the planet. The prototype looks like it's higher off the ground, as well, which should help the next president to avoid an embarrassing moment. There's no word on whether the Beast 2.0 will be ready in time for the next president presidential inauguration in January, but our photographers report that GM recently stepped up its testing for the limousine at its Milford Proving Grounds.
