Cadillac CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.

GM recalls Chevy Impala, Cadillac XTS for braking problem

Back in April, General Motors launched an investigation into braking issues affecting the 2014 Chevy Impala. Now there's a recall of both the Impala and the Cadillac XTS with which it shares its Epsilon II platform.
The issue apparently revolves around the electronic parking brake, which may not properly disengage. As a result, the rear brake pads could rub the rotor even while the vehicle is in motion, causing "significant heat, smoke and sparks." The earlier investigation had been launched following a complaint regarding the forward collision avoidance system, which is now either appears to have been unrelated or possibly a symptom of this larger issue.
The recall affects 2013-15 XTS models manufactured between February 14, 2012, and August 22, 2014, as well as 2014-15 Impalas manufactured between January 15, 2013, and August 22, 2014. The total number of affected vehicles reported by the National Highway Traffic Safety Administration comes to precisely 132,921 units, while The Detroit News reports a higher total of 205,000 units - the difference potentially coming down to the scope within the US and more broadly across North America. Dealers will contact owners to update the software in order to fix the problem.

2022 Cadillac CT5-V Blackwing First Drive Review | Peak oil

We may have embraced the coming of electrification. We may love a good, high-performance hybrid or EV. We could quite frankly not care less how a car makes power, so long as the end result is satisfactory. But man, nothing suits a big, square-shouldered American sedan quite like a V8. Question our commitment to Mother Gaia if you must, but the blat of a small block is the bass line in the song of American speed. And now onstage for the V8's farewell tour is the 2022 Cadillac CT5-V Blackwing, a midsize, manual-transmission luxury sedan that comes out swinging with a hand-built, supercharged 6.2-liter V8 making 668 horsepower and 659 pound-feet of torque. The CT4-V Blackwing may be great in its own right, but it's still down a pair of cylinders. The old Cadillac CTS-V (S not 5) was never the slimmest, sharpest or most luxurious sport sedan money could buy, but it always offered excellent performance for its price. It was also one of the few midsize manual transmission holdouts, at least until the third-generation V model debuted in 2016; for its brief run, it was offered only with the eight-speed automatic. Its spirit lives on in the CT5-V Blackwing, but Cadillac refined the formula significantly for its transition to the updated Alpha platform. The manual is back, it gained 28 horsepower and 29 pound-feet of torque, and the aerodynamics and braking were completely overhauled for this, the final iteration of the V8-powered Cadillac sport sedan. Apart from the larger footprint and all that comes with it, most of the Blackwing formula carries over almost unchanged to the CT5-V from its smaller CT4-V sibling. A six-speed manual gearbox is standard with a 10-speed auto available as an upgrade (which it truly is, in some ways). The electronically controlled mechanical limited slip differential, fourth-generation Magnetic Ride Control and various other tweaks made their way here too, but there are a few noteworthy deviations. Let’s start where the CT5-V stops: the brakes. Since the larger, heavier CT5 needs more braking capacity, its wheels grew an inch in diameter to accommodate a bigger set of stoppers. The wheels are wider too, the better to fit its Michelin Pilot Sport 4S tires in 275/35ZR19 (front) and 305/30ZR19 (rear) – 20 mm wider up front and 30 mm wider out back than the 18-inch tires on the smaller CT4-V Blackwing. Exclusive to the CT5 is a carbon-ceramic brake package that reduces unsprung mass by 53 pounds and rotating mass by 62 pounds.
