GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

2020 Cadillac CT4 spied completely undisguised for the first time

A few weeks ago, Cadillac gave us our first look at its new small luxury sports sedan in the form of the CT4-V. This was a bit unusual considering the company hadn't shown us the regular one yet, and the reveal is still off in the not-too-distant future. But we were lucky enough to catch a normal 2020 Cadillac CT4 parked at a local gas station completely and totally undisguised. Based on what we know about other recent Cadillacs and their trim and design, this CT4 is probably a Luxury or Premium Luxury trim, since it has plenty of bright chrome and red taillights instead of dark gray ones. The differences from the CT4-V are subtle. The mesh grilles of the V are swapped for a main grille studded with small Cadillac badge shapes and the lower grille has simple slats. The little air intakes by the lower sections of the running lights are smaller than the ones on the V. This car also lacks the V's side skirts and wider canards on the edges of the front bumper. There doesn't appear to be a rear spoiler either. While we've had a good look at the exterior of the CT4, we'll have to wait until the car's full reveal later this year to know what's under the skin. We do know that it will continue to use the Alpha platform shared with the CT5, Camaro and the old ATS and CTS. We suspect the base engine will be the same 2.0-liter turbocharged inline-4 from the CT5, which makes 237 horsepower and 258 pound-feet of torque. Since the CT4-V uses a turbo 4-cylinder that makes 320 horsepower and 369 horsepower, there might not be a V6 option for the regular CT4. The CT5's twin-turbo 3.0-liter V6 makes more power and torque, so that's out, and the old ATS's naturally aspirated V6 made 335 horsepower and 285 pound-feet of torque, which would be uncomfortably close the CT4-V's specs. But we could see a V6 of some sort in an even more potent V iteration of the CT4 later.

President Trump's new limo spotted testing at high speed

What you're looking at is no ordinary limo. Look past the swirly camouflage and you'll see what appears to be a Cadillac, but don't let those looks fool you. This is the new Beast, otherwise known as Cadillac One, and codenamed by the Secret Service as Stagecoach. This is the car that will shuttle President Trump to and fro. It's hard to get a sense of scale from these images, but this car is huge. It's very likely built atop a heavy-duty truck platform, which is necessary due to the thick armor-like bodywork that's hermetically sealed to keep POTUS safe and sound. It's hard to tell for certain, but it appears this Beastie is riding on Goodyear Regional RHS II tires, which would otherwise be used on trucks and buses. Translation: this thing is heavy. The Beast is ostensibly badged as a Cadillac, and it wears the latest version of Caddy's corporate grille, badge, and upright headlamps at the front. From the rear, there's a hint of Rolls-Royce Phantom, with rear glass that tapers elegantly into the deck lid. In between is a massive slab-sided passenger compartment that's rumored to seat as many as seven passengers. These shots were snapped at GM's Milford Proving Grounds. It seems The Beast is undergoing some high-speed tests, though high-speed here is relative. Those Goodyears are only rated for 70 miles per hour or so, and we doubt the big 8.1-liter gasoline-fueled V8 engine is geared to push the President much faster than that, anyway. Related Video:
