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 Blackwings will get manual transmissions and 3D-printed parts

Cadillac's upcoming 2022 CT4-V and CT5-V Blackwing will be the first GM production cars to utilize 3D-printed technology. In fact, the technology will be featured front and center on one of the cars' most hotly anticipated features — in a decorative medallion atop the shift knob of the manual transmission. Cadillac says that "additive manufacturing" (named as such because 3D printing accumulates tiny deposits of material to create the object) made the manual transmissions possible by reducing costs and waste. Aside from the medallion, the cars will employ two 3D-printed two HVAC ducts and an electrical harness bracket. "[The manual transmission is] something we know V-Series buyers want and itÂ’s something we knew we had to have, so we used innovative processes to make it happen,” said Cadillac performance variant manager Mirza Grebovic. Speaking of which, Cadillac commissioned a Harris Poll survey about manual transmissions and received some interesting results. For example, 66 percent of American adults surveyed know how to drive manual, and 55 percent said they've owned a standard shift car. Of those who don't, roughly 40 percent are either somewhat or very interested in learning. Interest is highest among two key demographics, 64 percent of those earning $75,000 or more in annual household income, and 62 percent of those ages 18-34. The findings seem to contradict what many automakers have said about lack of interest in manuals, with some declaring a sub-1 percent take rate when manuals are offered. Perhaps with a performance-oriented car such as the V-series, buyer preferences change. The mix of old school gearboxes and new school manufacturing techniques will result in what looks like a very potent car on paper. The CT5-V Blackwing is rumored to be powered by an updated 6.2-litter V8, while the CTS-4 Blackwing is said to be motivated by a turbo six. Neither will use the twin-turbo 4.2-liter V8 of their namesake, but they should prove to be worthy successors to the CTS-V and ATS-V. Related Video:

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
