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.

Recharge Wrap-up: BMW to test autonomous cars, Korea bans sales of BMW, Nissan, Porsche models

BMW will test autonomous cars on public roads by the second half of 2017. The German automaker, with partners Mobileye and Intel, will operate a fleet of 40 self-driving vehicles using a "scalable architecture" that will be made available to other automakers. The partners plan to offer products ranging from key components to "a complete end-to-end solution" for autonomous driving. Since parting ways with Tesla, Mobileye also recently announced it would provide its technology to Lucid Motors. For BMW, it all leads up to its fully autonomous iNext model slated for introduction in 2021. See the video above, and read more in the press release from Intel. South Korea has banned the sale of certain models from BMW, Nissan, and Porsche over emissions cheating. Following an investigation, regulators determined emissions testing documents to be falsified. The country's Ministry of Environment has fined the three automakers a total of $5.9 million, and revoked the certification of 4,523 vehicles across banned 10 models. Six of the models were still on sale, while the other four have been discontinued. Read more from Automotive News Europe. China's prices for the Cadillac CT6 Plug-in are significantly higher than those announced for the US. The plug-in hybrid version of the luxury sedan recently went on sale with the two variants priced at RMB 558,800 and RMB 658,800. At the time of this writing, that's $80,420 and $94,812. Cadillac announced it would bring the CT6 Plug-In Í– which is built in China – to the US in the spring of 2017, starting at $76,090 before federal and local tax incentives. Hybrid Cars points out that China's own generous incentives could help to make it more competitive. The offering of a charger with free installation as well as an eight-year warranty on the electric powertrain should help, too. Read more at Hybrid Cars. A Connecticut court has ruled in favor of Tesla's gallery showroom in Greenwich. Last May, the Connecticut Automotive Retailers Association brought the suit to block the showroom on Greenwich Avenue, which has now been dismissed by the Connecticut Superior Court. Tesla cannot offer test drives, sell cars, or operate a Supercharger at the location, but it can sell other branded items and educate the public about its vehicles. It's possible that the issue of Tesla's direct sales model could come up again this year in Connecticut state legislature. Read more at Teslarati .

2020 Cadillac CT4 revealed in non-V form

We got our first look at the 2020 Cadillac CT4 when its V variant made its debut a few months ago. Now the company is officially showing off the regular CT4 luxury sport sedans. They actually don't look all that different from the V, though - especially the CT4 Sport trim. The Luxury and Premium Luxury trims are distinguished by less aggressive ground effects and a grille studded with chrome pieces shaped like the Cadillac logo. The interior is similar, too, complete with an 8-inch touchscreen. Super Cruise will be made available on the CT4 later in 2020, including on the V model. Really, the big news is the powertrain as V6 engines have been dropped entirely from Cadillac's compact sedan. The base CT4 engine available in Sport or Luxury trim cars is a turbocharged 2.0-liter four-cylinder making 237 horsepower and 258 pound-feet of torque. Coupled to either rear- or all-wheel drive, it features cylinder deactivation and an eight-speed automatic transmission. Unlike in the old ATS, a manual transmission is not available. One notable mechanical difference between trims is the Sport trim gets standard Brembo brakes. Moving up from the 2.0-liter engine is the turbocharged 2.7-liter four-cylinder introduced on the CT4-V. Available on the Premium Luxury trims, its output is downgraded to 309 hp and 348 lb-ft of torque from the CT4-V's output of 325 hp and 380 lb-ft. It too has cylinder deactivation and can be had with either rear- or all-wheel drive. The only transmission offered is a 10-speed automatic. The V model also gets Brembo brake upgrades, and with rear-wheel drive includes Cadillac's magnetically controlled adaptive suspension. Cadillac will start taking orders for the CT4 later this year, but pricing has not been announced yet.
