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.

GM to announce second U.S. battery plant, in Tennessee, with LG Chem, sources say

General Motors and South Korean joint-venture partner LG Chem will announce a second U.S. battery cell manufacturing plant on Friday, revealing plans for a $2.3 billion factory in Spring Hill, Tennessee, three people familiar with the matter said. The plant will use a different, more cost-effective battery chemistry than the one the companies will offer from the joint-venture plant they are building in Lordstown, Ohio, the sources said on Wednesday. The battery will be for the Cadillac Lyriq electric crossover vehicle that GM will begin building at its nearby Spring Hill assembly plant next year, the sources said. The timing of the Tennessee battery plant's opening is unclear, but there will be a period when the battery is supplied for the Lyriq by another LG facility until the Tennessee plant opens and it will not come from Lordstown, one of the sources said. GM would not confirm the details and declined further comment, and a spokesman for LG did not have an immediate comment. A Tennessee economic development spokeswoman also declined to comment. The No. 1 U.S. automaker previously said it was exploring the feasibility of another U.S. battery cell plant with LG's battery unit, LG Energy Solution, via its Ultium Cells LLC joint venture. Sources previously told Reuters that GM and LG Chem were in advanced talks with Tennessee officials, and that the plant there would be similar in scope to the $2.3 billion Lordstown plant. GM said in October it would invest $2 billion in Spring Hill to build EVs. The Detroit automaker said last year it was investing $27 billion in electric and autonomous vehicles over the next five years. Sources previously said GM would need more battery plants beyond the Tennessee one to meet aggressive EV targets. GM has set a target in January of halting sales of light-duty gasoline and diesel-powered vehicles by 2035. LG Energy said last month it planned to invest more than $4.5 billion in U.S. battery production over the next four years, including plans to build at least two new plants. LG had been embroiled in a high-profile dispute with rival South Korean firm SK Innovation in the United States after LG alleged SK stole trade secrets, but the companies settled that and other disputes with SK agreeing to pay $1.8 billion to LG.

2020 Cadillac XT5 makes its official debut, adding a new engine and improved tech

The 2020 Cadillac XT5 is here, and it’s new in some significant ways. To start, it gets a slightly revised look. We got a preview of it a month ago when Cadillac revealed the car in China, but these are official U.S.-specific photos now.  YouÂ’re looking at pictures of the XT5 Sport and Premium Luxury here. We mention this because Cadillac is continuing in its “Y” trim strategy of offering a Luxury, Premium Luxury and Sport version of their cars with noticeable design differentiation between each one. The Sport gets a darker appearance package with the XT4-like grille, as opposed to the Premium Luxury that is set to emphasize bright trim (i.e. chrome).  WeÂ’re expecting a noticeable change in the driving experience for the 2020 XT5, as the new base engine is the 2.0-liter turbocharged four-cylinder that debuted in the XT4. ItÂ’ll be making 237 horsepower and 258 pound-feet of torque in this application, just as it does in every vehicle GM is spreading it to. The 3.6-liter V6 is standard on the Sport (optional on Premium Luxury), and continues to make 310 horsepower and 271 pound-feet of torque. Both engines are paired with nine-speed automatic transmissions now — the V6 was paired with an eight-speed previously.  Cadillac has also spent some time with the suspension, giving the non-Sport trims “revised front struts and driveline enhancements to improve ride comfort and road isolation.” We like the sound of that. Then, the Sport trim is legitimately sportier than the Luxury trims. Cadillac has fitted its continuous damping control adaptive suspension, given it quicker steering, standard all-wheel drive and standard 20-inch wheels. All that should make it slightly more lively through the twisties. A smattering of tech updates are coming onboard for 2020. Cadillac added its rotary controller that lets you control the updated infotainment system via that device or through the touchscreen. Available wireless phone charging, revised USB ports and USB Type-C ports come on the 2020 XT5. Then youÂ’ll notice new interior color and trim gracing the interior surfaces, as well. Cadillac says there are more “authentic materials” than before, so hopefully that means less plastic. What Cadillac made no mention of in its release, is Super Cruise. ItÂ’s going to be coming to the recently revealed CT5 and CT4-V sedans, but Cadillac doesnÂ’t seem particularly keen to get it on the crossovers yet.
