2021 Cadillac CT4 Review | A joy to drive, a puzzle to compare

Cadillac's smallest sedan is arguably its most competitive. The question is, though, what does the 2021 Cadillac CT4 actually compete with? It has the price tag and interior in keeping with the growing number of sub-compact luxury sedans, yet its rear-drive layout and sophisticated chassis are more akin to sedans that are a size up. It sure drives more like a BMW 3 Series than something smaller and cheaper. Actually, it could easily be argued that the CT4 is a more rewarding sport sedan than BMW's benchmark – be it the Premium Luxury you see above or spicier CT4-V trim.  That's where the comparison ends, however. The CT4 is smaller, with a cramped back seat and rinky-dink trunk. Its cabin quality is lower and its engines less refined. Yet, it is sufficiently cheaper to justify all of the above. For the dwindling few who still prize communicative steering and an unflappable suspension in their entry-level luxury sedan, the CT4 is a terrific choice – no matter what you compare it to. What's new for 2021? The CT4 was all-new last year, so there are only minor updates for '21. A 12-inch HD instrument cluster is now available as part of the Technology package in top trim levels, while Cadillac's Super Cruise semi-autonomous driver assist system will be a late-availability option. Wirelessly connected Apple CarPlay and Android Auto are now standard. There's also a new Diamond Sky Special Edition that adds a unique color scheme and trim finishes.  What's the CT4 interior and in-car technology like? We've criticized the design and quality of other Cadillac interiors, and although the CT4's is awfully similar to those, its lower price and market positioning make it far more competitive and, well, palatable. It may not be as expressive as the Mercedes A- or CLA-classes, but for the money, we don't think you'll be disappointed. The infotainment system is controlled by an 8-inch touchscreen with a pair of redundant control knobs better suited to scrolling through playlists, radio stations or other menu functions. One is adjacent to the screen and volume knob, while the bigger one is on the center console. We like this setup quite a bit and appreciate the Cadillac's system's clean look and quick responses. The base setup includes wirelessly connected Android Auto and Apple CarPlay, plus Amazon Alexa integration and a choice of USB Type-A and Type-C charging.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

2020 Cadillac CT4-V, CT5-V revealed, less powerful than predecessors

Expectations have reached stratospheric heights for the 2020 Cadillac CT4-V and 2020 Cadillac CT5-V, and for good reason: Their ATS-V and CTS-V predecessors were potent sports sedans with gobs of power and handling and braking to match. Now the new sedans have been revealed, and they're not what we expected. They each lose two cylinders compared with the other vehicles, and on paper, they don't look as capable. But we do have hope that these won't be the end-all, be-all performance Cadillacs. First, let's look at the cars. The CT4-V will be the base of the V brand, and it's our first look at the small luxury sedan. It has a roofline and window treatment more like past Cadillacs, eschewing the C-pillar garnish of the CT5. It also naturally gets dark trim and headlights, a unique spoiler and quad tailpipes to distinguish it as a V. Under the hood is a turbocharged 2.7-liter four-cylinder that is based on the engine in the new Chevy Silverado. It makes 320 horsepower and 369 pound-feet of torque, a far cry from the ATS-V's 464 horsepower and 445 pound-feet of torque. Cadillac CT4-V View 12 Photos Power goes through a 10-speed automatic transmission only. Both rear-wheel drive and all-wheel drive are available. It gets a mechanical limited-slip differential whereas the ATS-V had an electronically controlled limited-slip differential a la Camaro ZL1. The brakes have four-piston calipers at each corner versus six-piston front units and four-piston rear units on the ATS-V, and the rotors are smaller. Magnetic Ride Control remains standard on the rear-drive version, but the all-wheel-driver version sticks with conventional shocks. The new CT4-V is about 200 pounds lighter than the ATS-V, though, and it has 50/50 weight distribution. Additionally, both the CT4-V and the CT5-V have Super Cruise available as an option. Moving on to the CT5-V, it looks like a regular CT5 but with dark trim and lights, quad tailpipes and a unique rear diffuser. Instead of the CTS-V's 640-horsepower supercharged V8, the CT5-V uses a twin-turbo 3.0-liter V6 making 355 horsepower and 400 pound-feet of torque. Changes made to the 3.0 for the CT5-V include a new intake system and new exhaust, and it revs higher too. Like the CT4-V, it comes with a 10-speed automatic and either rear-wheel drive or all-wheel drive. It does get the electronically controlled limited-slip differential.
