2019 Cadillac XT5 Sport package isn't really that sporty

Between the just revealed XT6 three-row crossover and last year's XT4 compact, the stalwart midsize XT5 has been a bit neglected. But Cadillac is giving it a little love at the Chicago show with the introduction of the Sport package. Don't get too excited, though, because this package is just a trim group. Outside, the XT5 with the Sport package gets a black grille, LED lights all around, and the rear lights have clear lenses. These design cues line up with the existing Sport trims on the XT4 and XT6. The new lighting and trim are complemented by 20-inch dark gray wheels and side steps. Inside, buyers get a choice between an all-black or black and gray upholstered interior with diamond-cut aluminum trim and aluminum pedals. And that's all the package adds. The suspension isn't retuned. The 3.6-liter V6 still makes 310 horsepower and 271 pound-feet of torque. But if the looks are enough for you, you'll be able to add the package to either the Luxury or Premium Luxury trim levels, which sit between the base XT5 and top-level Platinum. Related Video:

Cadillac Celestiq flagship EV shows off its tint-shifting smart roof

GM has high hopes for its upcoming Cadillac Celestiq sedan, slated for release in 2023. The flagship EV is being built to help the brand recapture its reign as “the Standard of the World.” As such, itÂ’s expected to arrive packed to the gills with cutting edge, futuristic technology including an all-glass roof that can adjust its opacity anywhere between crystal clear and completely opaque with the mere flick of a switch. These roofs, dubbed SPD-Smartglass, have been designed and manufactured by Research Frontiers of Woodbury, New York, and are based on Suspended Particle Device technology that was originally created as a replacement for the manual sliding window shades aboard commercial aircraft, Research Frontiers CEO Joe Harary told Engadget. Some of the earliest examples of SPD window treatments can be seen on the 2011 Mercedes Benz SLK roadster and in the 2012 Mercedes S Class coupe, which were used to increase headspace while eliminating the physical window shade screens, as well as various McLaren models over the past decade. As the YouTube video below explains, Research Frontiers SPD tech relies on polyiodide nanoparticles to generate its tint effect. Magic Sky Control Using SPD-SmartGlass Technology “SPD technology is smart glass that allows you to change the tint of the glass,” Harary explained. “There's this film that we invented that has little nanoparticles in it, which you can control with a small electrical voltage. So, basically this film... that allows you to dial in whatever tint level you'd like.”  “The crystals are about three to five tenths of a micron in length and they act as induced dipoles so when you apply an electric field to conductive coatings in the film,” Harary continued, “ the particles will line up, and allow light to pass through. Then, when you remove the voltage, their natural tendency is to be in the dark state due to Brownian movement and that causes the glass to tint.”  As the tint partially blocks incoming photons, it also reduces the amount of glare experienced by the driver and the heat trapped within the vehicle — over 99.5 percent of light and 95 percent of heat, per a January press release from the company. The claim is, this allows vehicle occupants to stay comfortable for longer without having to turn on the A/C, as well as keep the interior up to 18 degrees Fahrenheit cooler overall, Harary said.

2020 Cadillac CT5 in New York: 7 questions with the chief engineer

Cadillac revealed the 2020 CT5 at the New York Auto Show, and we decided to sit down and have a chat with chief engineer Mike Bride to learn more about the car. You can read our reveal post here to get the full download, and then read on below to learn a bit more. Cadillac is still rather coy about any performance model to spawn from the CT5, but things appear to be looking up after our conversation that you can read below. Q: What's the driving nature of this car? Should we expect something similar to the CTS and ATS? A: Yes, you can see it's built off the rear-wheel-drive architecture. Our goal was to retain all of that fun-to-drive nature. Direct steering feel, responsive handling. Going forward, we ask how we can continuously improve, and that was really about driving more sophistication in the ride, a much more mannered car that's better for impact harshness and rolling isolation, really provides comfort when you want comfort over tire strips and heaves in the road. Really getting that level of isolation, but not compromising that handling and direct steering feel of the Cadillac sedans we've grown accustomed to. Q: How is this car different from the CTS underneath, and other Alpha platform cars? A: I would say this is a major revision. A lot of new parts, a lot of new part numbers, a significant evolution. In the suspension space, the links are all new, and there's been a lot of work done in isolation, so the bushings and strut mounts are all new. We've evolved the Alpha platform to now get the ride control and road isolation, the comfort aspects of it all. There are a lot of structural improvements like a changed wheelbase, an evolution in rear foot-swing and foot space from the fuel tank area to get in and out of the car better. As we developed this structure, it was about overall structural body stiffness, and impedance at the chassis attachments to really get that level of isolation from road inputs. We try to have a calm floor, a steering wheel that doesn't vibrate, and quiet to the driver's ear. Those were the paths we went after to really drive the structure to the right stiffness requirements, structural integrity, a lot of development into suspension bushings, tuning elements, strut mounts. We have a new damper technology, a ZF damper. It has MVS damper technology. It's a multi-valve system that provides less harshness from an NVH standpoint and a great optimization balance of motion control with ride inputs.
