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.

Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

What are the odds an actual Cadillac EV looks anything like this?

The Cadillac EV concept sure looks neat. It's all-electric, too, which is even neater. Unfortunately, it's a concept car, and when it comes to concept cars with Cadillac badges on them, it's best not to get too excited. For instance, you might recall this exquisite piece of automotive art. It was called the Elmiraj. You might recall the production version became the bold face of a new Cadillac and inspired a renaissance for the brand. Jay-Z drives one. Oh wait, no he doesn't. It was never made, nor was anything like it made. This is the Cadillac Escala. It has certainly inspired design cues on production Cadillacs, most notably the just-revealed XT6. However, besides those cues, it's a pretty anonymous large crossover. Hardly anything as stunning as the Escala. Now, perhaps the CT5 will be a dead-ringer, but we wouldn't get our hopes up. Then there's this, the Ciel. Not to be confused with an Acura CL, it was 100 feet long, a convertible and purple. This was also not made. OK, we can see why. And finally, this is the Cadillac Sixteen. As the name suggests, it had 16 cylinders. That's a lot. The most you can get in a Cadillac today is half that many. Now, to be fair, most manufacturers produce concept cars that have zero chance of production. They are meant to serve as inspiration for future designs, showcase future technologies or just draw attention to the brand. The problem with the Cadillac concepts is that they're not that fanciful. Those aren't pod-like Jetsons cars up there. They aren't this nonsense. They look like modern interpretations of the exact sort of grandiose cars Cadillac used to make. The very cars that made Cadillac the "Cadillac of the World." You know, like this. I'm not talking about literal tail fins and pink paint, but that's a CADILLAC. It's confident. It's its own thing. It doesn't need to beat BMW around the Nurburgring to prove something to someone somewhere. The Elmiraj was also a CADILLAC. The XT6 literally wears a Cadillac badge, but it could be anything. By contrast, Lincoln is doing a much better job of tapping into the spirit of its grand past with the Navigator, Aviator and suicide-doored Continental. Nowhere is that better seen than in the cabins of the XT6 and Aviator. One is swank. The other is not. But back to where we started: that EV concept. You'll note that it doesn't actually have a name.
