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.

These are the top luxury cars bought by people entering the segment for the first time

Let's say you just got a big promotion at work or the kids are moving out of the house, and you finally have some extra money. You decide to blow it all at once and treat yourself by upgrading your ride. Naturally, you look to a luxury automaker. What do you choose?
Models like the Audi A3 and Mercedes-Benz CLA-Class may be tailor-made to introduce buyers to the premium segment, but a new study finds that they don't garner the highest rates of non-luxury customer conquests. It turns out that a Volvo leads among folks moving up to a premium brand, and it isn't even one that's made anymore, at that.
A recent study by Polk and IHS Automotive looked at what models had the highest rates of buyers upgrading from a non-luxury segment. The information comes from its new vehicle registration data through April 2014. All ten top models boasted conquest rates of over 50 percent, but the Volvo C70 led the field with 68.01 percent of its customers coming from non-premium brands.

GM and LG Energy Solution will build their second battery plant in Tennessee

DETROIT — General Motors and South Korean joint-venture partner LG Energy Solution on Friday said they will build a second U.S. battery cell manufacturing plant, revealing plans for a $2.3 billion factory in Spring Hill, Tennessee. The planned 2.8 million-square-foot plant, scheduled to open in late 2023, will employ 1,300 people and will have production capacity of about 35 gigawatt-hours, similar to the companies' Ultium Cells joint-venture plant in Lordstown, Ohio, as they move to respond to the growing demand in the electric vehicle market. The plant's capacity would enable it to supply battery packs for more than 500,000 electric vehicles a year. "The addition of our second all-new Ultium battery cell plant in the U.S. with our joint venture partner LG Energy Solution is another major step in our transition to an all-electric future," GM Chief Executive Mary Barra said. The United Auto Workers on Friday called on GM to ensure the new plant is staffed with union-represented workers, which GM officials have said would be determined by the employees. LG Chem said in a regulatory filing that its LG Energy Solution unit will invest $933.5 million in the plant between this year and 2023. GM and LG Energy Solution will use a different, less-expensive battery chemistry in Tennessee than the one to be used in the Lordstown plant that opens next year, sources previously told Reuters. Sources have said the No. 1 U.S. automaker will need more battery plants beyond Tennessee to meet aggressive EV targets, including projected sales of more than 1 million EVs globally in 2025. GM's longer-range target includes halting sales of light-duty gasoline and diesel-powered vehicles by 2035. Most battery manufacturing is currently concentrated in China and Korea, while Tesla and Japanese partner Panasonic largely control most U.S. battery production. When it opens, the new GM-LG battery plant will supply batteries for the Cadillac Lyriq crossover EV that GM is slated to start building at its nearby Spring Hill assembly plant next year. LG is expected to supply the batteries from Korea until then. Supplier sources said a second Cadillac electric crossover, called Symboliq, is expected to join the Lyriq in production at Spring Hill in 2024, along with two new electric crossovers for Honda and its premium Acura brand. GM said in October it would invest $2 billion in Spring Hill to build EVs.
