Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

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.

Cadillac XT5 caught uncovered during photo shoot

It's only been a few weeks since Cadillac announced that its replacement for the SRX, the new XT5, is on its way. Now, we have images of it out in the open and completely free of camouflage. Obtained by a reader at Jalopnik's Opposite Lock forum, the Caddy was spotted during what user Saw930 believes was a photo shoot in New York's trendy SoHo neighborhood. There's only a pair of images, from the front and rear three-quarters, but it's enough to give us a very thorough overview of the exterior styling on the new CUV. In short, the design language that has been seen on Escalade, CTS, and upcoming CT6 has indeed made its way to the SRX replacement. The broad, egg-crate grille is perhaps the cleanest iteration of Caddy's latest styling, while the CT6-inspired headlights look sharp, as well. Expect a similar headlight pattern to the CTS, with strong LED character accents on the outside of the headlights that integrate seamlessly with the lower DRLs. In back, the taillights curve over the rear haunches and blend into an extremely strong shoulder line. It's a dynamic and aggressive piece of design that we'll need to see in person before signing off on. The rear bumper, meanwhile, is a nicely styled piece, complete with twin, integrated, rectangular tailpipes that flank a piece of (probably faux) skid plating. There's a similar off-road treatment in the front bumper, as well. While we wait for scour for more news on the XT5, have a look at the two images Saw930 captured and posted at Oppo and let us know what you think in Comments.
