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 confirms 'Blackwing' name, manual gearboxes for pumped-up CT4-V, CT5-V

Cadillac officially confirmed Tuesday that the high-output variants of its new CT4-V and CT5-V sedans will be dubbed "Blackwing," sharing a nameplate with GM's stillborn twin-turbocharged V8. As an added bonus, company representatives said for certain that both of Cadillac's new super-sedans will be offered with a manual transmission, confirming long-standing rumors to that effect.  "The Blackwing name has come to represent the very best of Cadillac performance engineering, craftsmanship and technology," said Cadillac chief engineer Brandon Vivian. "The new CT4-V Blackwing and CT5-V Blackwing build on the brand’s respected legacy of ultimate-performance driving experiences and elevate them even further." Cadillac says the two Blackwing sedans, which are successors to the critically acclaimed ATS-V and CTS-V, will represent "the apex of Cadillac performance and driver engagement." The company also remained mum on just what to expect in terms of capability, teasing only the fact that both the CT4-V and CT5-V Blackwing posted quicker lap times in testing at Virginia International Raceway earlier this year than their predecessors did.   Rumors have pointed to the CT5-V Blackwing making use of the company's supercharged 6.2-liter V8, which also powered its predecessor. The 6.2 shares its architecture with the company's flagship, naturally aspirated V8, making it an economical choice for powering performance cars. The smaller CT4-V is likely to be motivated by a turbocharged 6-cylinder. They will also be available in limited numbers, though Cadillac's announcement did not elaborate on just how many (or few, as the case may be) will eventually be built, or how many model years to expect. The CT6-V, which carries the 4.2-liter V8 that shares the "Blackwing" name, saw only limited production before being axed.  The V8 itself may find a new home down the road, but for the time being, it's toast.  Cadillac assured us that more information on the new CT4-V and CT5-V Blackwing will be come along soon enough. For now, at least we know what they're going to be called.  Related Video:    

Cadillac developing stretched ATS-L just for China

To luxury automakers, long-wheelbase sedans are to China that crossovers and SUVs are to the US, so it isn't all that surprising any more when the latest sedan gets an extra couple of inches between the wheels to improve rear-seat comfort. According to Car News China, the next sedan to get the stretch will be the Cadillac ATS, which will increase the wheelbase by 10 centimeters (about four inches) to become the ATS-L.
Designed to go up against rivals like the BMW 335Li and the added-length Mercedes C-Class, the ATS-L will reportedly be built locally in China with an engine list that will grow as well. Currently, only the 2.0-liter turbo engine is offered in the ATS in China, but the ATS-L will get the full spectrum of ATS engines including the base 2.5-liter and the peppier 3.6-liter V6. This isn't the first time Cadillac has offered a China-specific stretched sedan either as the SLS dates back to 2006.
