GM's Cruise Origin EV platform to be shared by many electric vehicles

GM on Monday announced that it was spending $2.2 billion at its Detroit-Hamtramck facility, part of its $3 billion commitment made after the UAW strike to transform Hamtramck into the company's first plant to exclusively build a wide variety of electric and autonomous vehicles. The operation will eventually employ 2,225 people. Hamtramck is still building the Cadillac CT6 and Chevy Impala. Production of those cars will wind down Feb. 28, when GM will idle the lines for 18 months of retooling. During the transition, more than 800 workers will likely be transferred to build pickups at Fort Wayne, Indiana, or Flint, Michigan. When Hamtramck production of new EVs begins in late 2021, the Cruise Origin electric shuttle revealed last week will be among the first vehicles built there. Also, an electric pickup likely branded as a Hummer to be sold as a GMC, which will be debuted by LeBron James during the Super Bowl this Sunday. GM made quite a few pronouncements during the unveiling of the electric, autonomous Cruise Origin last week in San Francisco. We heard that the Origin was designed to last for for 1 million miles, be "roughly half the cost of what a conventional electric SUV costs today,” and riders could save as much as $5,000 per year by giving up their cars for Origins. Much was left out, as well, such as detailed specs on the platform, and when the Origin could see wide deployment. Carscoops addressed one open question about the platform, reporting that the Origin's bones will be shared among a number of other GM battery-electric vehicles, probably starting with the Cadillac EV due in 2021. The site received confirmation of that tidbit from Megan Soule, the automaker's assistant manager of Electrification, Battery Technology, Fuel Cells, R&D and GM Ventures Communications. It seems what we've been shown in the Origin is the first fruit of the multi-vehicle EV strategy GM CEO Marry Barra presented at the 2017 Barclays Global Automotive Conference. One of the slides (below, full PDF presentation here) touts an "All new multi-brand, multi-segment platform" with a "Structurally integrated all new battery system." The next slide places that modular platform at the center of 11 new vehicles, the van-looking silhouette on the upper right labeled "SAV," for shared autonomous vehicle, apparently in reference to the Origin.

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.

Junkyard Gem: 1976 Cadillac Eldorado Convertible

Convertibles rode high well in 1960s America, with Detroit selling more than 500,000 ragtops in 1965, but sales collapsed by the early 1970s and tightening federal crash-safety regulations made it seem less worthwhile to even bother producing new ones. Chrysler halted convertible production after 1971, with Ford following suit by 1973. By the 1976 model year, the Cadillac Eldorado was the last new American car you could buy with a convertible top from the factory, and it appeared that none would ever be built again. I've found one of those "last convertible" Eldorados in rough-but-identifiable condition in a Denver junkyard. As it turned out, the convertible never really died in America. Car shoppers could still buy new European-made convertibles after 1976, coachbuilders modified new Detroit cars with factory-grade drop-tops, and then Chrysler began selling K-Car convertibles starting with the 1982 model year. Because the '76 Eldorado appeared to be the absolute end of the convertible line, however, buyers thought they were investing in a sure-fire collector car that would be worth vast sums in the not-very-distant future (this belief led to lawsuits against GM later on, when the Cadillac Division resumed production of the Eldorado convertible for 1984). While a one-of-200-made Bicentennial Edition Eldorado with red-white-and-blue trim really is worth plenty these days, an ordinary 1976 Eldorado in beat-up condition doesn't seem worth restoring. This car appears to have sat outside in Colorado with the top down for decades, filling with snow each winter and enduring high-elevation solar irradiation each summer. A 1960s GTO or Camaro might be worth fixing up after falling into this state of disrepair, but not one of 14,000 "last convertible" Eldorados made in 1976. GM's Unified Powerplant Package front-wheel-drive system, which used battleship-strength chains to transmit power to the drive wheels, proved to be extremely reliable on the street, joining the small-block Chevrolet engine and Hydra-Matic transmission in the pantheon of The General's Greatest Engineering Hits. Even gigantic motorhomes used this system. In 1976, the Eldorado got the last of the 500-cubic-inch (8.2 liter, or litre as GM's marketers spelled it) V8s, rated at a disappointing 190 horsepower and an impressive 360 lb-ft of torque.
