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.

More than 100 pink Cadillacs assemble for Aretha Franklin’s funeral today

Aretha Franklin's funeral service is under way today in Detroit, and plans call for a service of at least five hours featuring performances by stars including Stevie Wonder, Ariana Grande and Chaka Khan, speakers including former President Bill Clinton and the Rev. Al Sharpton, and at least 130 pink Cadillacs lining the road in front of the church. The gesture is a nod to Franklin's Grammy award-winning 1985 hit "Freeway of Love" and its lyrics about driving in a pink Cadillac. Crisette Ellis, the wife of Bishop Charles Ellis III of Detroit's Greater Grace Temple, said they were inspired by how police line up their cars during funerals for fallen officers. "My husband said, 'Wouldn't it be awesome if we could have a sea of pink Cadillacs parked on Seven Mile Road to greet Ms. Aretha Franklin as she arrives?'" she told NPR. Only in #Detroit. 130 pink Cadillacs drive in front of Greater Grace Temple ahead of #ArethaFranklin funeral. pic.twitter.com/qTTJtDXNvS— ROOP RAJ (@rooprajfox2) August 31, 2018 Ellis is an independent national sales director for Mary Kay Cosmetics, which famously rewards top sellers with pink Cadillacs, so she had a built-in base of people to call on for the favor. "They're coming from everywhere," she said. "They are coming from as far as Texas; Omaha, Nebraska; Florida; North Carolina; Maryland." The funeral, which officially kicked off at 10 a.m. EST at Greater Grace, caps a weeklong celebration of Franklin's life and songs, including a two-day visitation at the Charles H. Wright Museum of African American History and concerts. Performers also include Faith Hill, Jennifer Hudson and the Clark Sisters, while Tyler Perry and the Rev. Jesse Jackson are also scheduled to speak. HLN and the Word Network, plus several local Detroit television affiliates, plan to broadcast the funeral, and outlets including The Associated Press and USA Today plan to livestream it. Having sung at the inaugurations of three presidents — Jimmy Carter, Bill Clinton and Barack Obama — Franklin was an American institution. She was awarded the Presidential Medal of Freedom by then President George W. Bush in 2005. Clinton entered the church with his wife, Hillary, to loud applause and stood quietly by Franklin's open casket before the service started. Franklin's body was dressed in a golden sequined outfit. The funeral was closed to the public, but crowds of fans gathered outside, many dressed in their church best.

Cadillac Super Cruise, a hands-off review

Cadillac Super Cruise won't let you eat breakfast behind the wheel, climb in the back seat or any of the other stupid human tricks displayed on YouTube by Tesla owners. It even won't allow the car to change lanes on its own, like Tesla Autopilot. But it's a big step on the road to full autonomy, a huge convenience on long-distance road trips and a substantial technological triumph for Cadillac. In the simplest terms, Super Cruise is a lane-centering enhancement to adaptive cruise control (ACC). But Super Cruise is anything but simple. Its technical complexity — hence its long delay after first being unveiled five years ago — belies its straightforward operation and intuitive user interface, which I discovered on an almost 750-mile, 11-hour drive in a 2018 Cadillac CT6 between Dallas and Santa Fe to test the system. LOADS OF LIMITATIONS First, let's dispense with the details and disclaimers. Super Cruise is standard on the 2018 CT6 Platinum and a $5,000 option on other trim levels. Because Super Cruise is supported by OnStar — an OnStar operator will call to find out if first responders need to be sent in a worst-case scenario — a three-year OnStar Super Cruise Package is included with the system. Super Cruise has loads of limitations that are probably more concerning to GM's legal counsel than they were to me during my long drive. Some are no-brainers, such as not for use in construction zones or for driving on the shoulder. But the system can also be stymied by adverse weather, poor visibility and faded lane markings. Super Cruise only works on freeways with on and off ramps and a center divider. ACC and forward collision warning also need to be engaged, and the system's cameras and radar sensors can't be obstructed. To keep drivers from looking away from the road for too long — and to keep the system active — an infrared camera on top of the steering column keeps an electronic eye on the driver's seat. GM has over 100 patents alone on this Driver Attention System, including an algorithm that triangulates the nose, eyes and ears in case the camera can't see through sunglasses to make sure you're not nodding off. In addition to the car's visible sensors, another major component of the system is something you don't see: mapping software. But not the kludgy kind that powers in-dash navigation systems.
