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.

2020 Cadillac CT4 spy shots reveal sedan-heavy approach in age of SUVs

You're looking at some pictures of the 2020 Cadillac CT4, which will be smaller than the upcoming CT5. And since they're both smothered in similar-looking camouflage, which is specifically intended to confuse, you might think they look pretty similar. In isolated photos, it's sometimes hard to tell which sedan you're looking at. In fact, when we first saw this car recently, we also thought it was a CT5. Here's how we know they're actually two different cars. Some background: The CT5 is slated to replace the CTS, and to try and find the balance that the old car couldn't achieve in the lineup. Cadillac's former CEO previously stated that this car would also fill in for the ATS, which is on its way out. Whatever it ends up being, it'll have to make a clear case for itself against the CT6 — it can't be too close in size and opulence, or they'll hurt each other in sales. And the CT5 can't be too small, or it will struggle against traditional midsize luxury cars. The CT4 could further complicate matters for the exact same reasons, just in a smaller package. How small can Cadillac make it? It seems poised to replace the wonderful-to-drive ATS, which was as allergic to sales as the XTS. This will give Cadillac a three-sedan lineup: CT4, CT5, and CT6. Let's hope there's enough differentiation between them to prevent consumer confusion and sales cannibalization — and that consumers understand the CT6's promotion via attrition to top dog in the sedan lineup. With all that out of the way, let's look more closely at the CT4 (above left) and CT5 (right). The CT4's greenhouse stops closer to the centerline of the rear wheels than the CT5's. That gives the CT5 a visually longer, leaner look, more of a semi-fastback arrangement. The CT5's rear vanity window should resemble the CT6's, with a glass element behind the door opening. The CT4 will have a more conventional vanity window in the door, like the ATS. Perhaps the quickest "tell" is the size of the side-view mirrors, which are rounder in the CT4 and leaner in the CT5. Out back, the CT4 has a lower cutout for the license plate than the CT5. The exhaust outlets are also different, although that may change for production. Remember, the big full-width rear lights are probably misdirection on the part of the GM camo team. The entire rear decklid of the CT4 has more roundedness to it, while the CT5's extra width gives it more room up top to spread the decklid out a little flatter.

2020 Cadillac CT4 Review & Buying Guide | Cadillac recommits to the small sedan

The 2020 Cadillac CT4 is a brand-new entry into the baby luxury sedan space, replacing the ATS. With an excellent rear-wheel-drive chassis and a performance-oriented “V” trim (to be topped by a yet-wilder “Blackwing” model), the CT4 is aimed at the enthusiast end of the segment. Cadillac fields the lone American entry in this class, meaning the CT4Â’s main competitors — the Audi A3, BMW 2 Series Gran Coupe and the Mercedes-Benz A- and CLA-Classes — are all European. However, since it's a bit bigger than those and features a rear-wheel-drive platform (all-wheel drive is available), it's hardly an apples-to-apples situation. The Genesis G70 is perhaps a closer comparable. In any event, the CT4 is a compelling, American alternative that delivers excellent comfort, interior quality and driving dynamics at a price that strongly challenges the various competitors from Europe. What's new for 2020? The Cadillac CT4 is new for 2020, alongside the bigger CT5.

The Cadillac CT4 packs the sort of high-quality materials and convenience features one expects from an entry-level luxury model. The seats are comfortable and supportive, and in higher-end models, the front buckets are offered with heat, ventilation and massage features. The CT4 also boasts what GM calls a “sound-optimized” interior coupled with active noise cancellation and amplification to mitigate unpleasant frequencies and enhance desirable ones. In all, we find the CT4Â’s interior much more compelling than that found in other recent Cadillac products such as the new XT4 crossover. The infotainment system is controlled by an 8-inch touchscreen with an optional rotary-control interface. The base setup includes Android Auto, Apple CarPlay and Amazon Alexa integration and offers USB Type-A and Type-C connectivity and charging. Upgrades include navigation and multiple Bose audio packages, all of which bring with them wireless device charging. How big is the CT4? Like many of CadillacÂ’s previous sport sedans, the CT4 is a bit of an oddball size-wise for the segment it targets, stretching more than a foot longer than the Audi A3 and nearly 9 inches longer than the BMW 2 Series Gran Coupe. However, this doesn't translate into a comparable interior space advantage because of the CT4 rear-wheel-drive platform.
