GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

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.

Junkyard Gem: 1993 Cadillac Allante

The General's Cadillac Division had lost much of its status as a world-class styling and engineering innovator by the 1980s, while younger rich Americans signed on the line which is dotted for European luxury machines packed full of futuristic technology. Something needed to be done to win back the hearts of those buyers, and that something was the Cadillac Allante two-seater. Here's a final-model-year Allante, complete with one of the very first Northstar V8 engines, found in a Denver yard. The overhead-valve Cadillac V8 engine of 1949 shook up the automotive world, and the double-overhead-cam Northstar V8 of 44 years later had a similar effect. Finally, a high-revving, smooth-running modern V8 to compete with those pesky European and Japanese carmakers! Only the Allante got the Northstar at first, with other Cadillac models following soon after. After the underwhelming power output of the pushrod HT4100 V8s used in the 1987-1992 Allantes, the upgrade from 200 horses to 290 helped boost sales of the '93 to the highest annual figure ever achieved by the model: 4,670 cars. Unfortunately for GM, production costs of the Allante proved to be murderous in the long run. Shortened Eldorado frames were loaded onto specially-fitted 747s in Detroit and flown to Pininfarina's new Allante factory in Italy. After Pininfarina built the bodies, they got loaded onto the 747s, flown back to Detroit, trucked to the Hamtramck assembly plant, and given running gear there. GM called this system the "Allante Air Bridge" and it cost plenty. The cars looked both futuristic and Italian, which they were, but the Allante's price tag stood at heights far above those of the rest of the Cadillac line: $59,975 in 1993, or about $108,500 in 2020 dollars. You could buy a rear-wheel-drive BMW 850Ci with a 282-horse V8 and manual transmission for a mere 10 grand over the Allante's cost that year, or a Jaguar XJS convertible for just $56,750. The Allante had front-wheel-drive and a not-so-modern four-speed automatic transmission, which hurt sales among the enthusiast types who flocked to Cadillac showrooms for the CTS-V a decade or so later. No European machine of 1993 could top the Mars Base appearance of these vertically-arranged, all-pushbutton HVAC/audio controls, though.
