Chinese-made Cadillac CT6 Plug-In starts US sales

General Motors has started US sales of the Cadillac CT6 Plug-In after taking its first domestic deliveries of the China-produced sedan last month. The model is GM's first new plug-in hybrid in the US since the automaker discontinued sales of the ELR extended-range plug-in last year. The arrival and sales, first reported by InsideEVs, were confirmed by Cadillac spokesman Andrew Lipman. Not surprisingly, the sedan isn't cheap, as the CT6 Plug-In is priced at $75,095, or almost $12,000 more than the gas-powered variant, though that figure doesn't include federal and state tax credits for electric vehicles. For that tab, buyers get a 335-horsepower luxury car that can go 31 miles on electricity alone, and 0-60 miles per hour in a little over 5 seconds. The model gives GM three plug-in vehicles to sell to the American public, or the same number US competitor Ford offers. InsideEVs estimates that about 100 of the sedans have been delivered to US dealers, so the car remains a relatively low-volume affair. By comparison, GM's Chevrolet division has sold 5,563 Volt extended-range plug-ins and 3,092 Bolt electric vehicles through March. Cadillac sold 534 units of the ELR in 2016 after moving 1,024 the previous year. GM opted to produce the plug-in hybrid in China because of that country's receptiveness to new models that feature alternative and environmentally friendlier powertrains. Additionally, such production shortens the distance to the CT6's battery maker LG Chem, which is producing the car's battery packs in South Korea. On that note, GM has previously estimated that the Cadillac CT6 Plug-In will move more units in China than in the US. Related Video:

Remembering Pierre Cardin's automotive legacy

Pierre Cardin has passed away at age 98, and while the designer had a great impact on the world of fashion, he also brought his signature style to the automotive realm, chiefly with the unlikely partner of American Motors. At the dawn of the 1970s, AMC decided to seek out a little glamour for its freshly renewed product lineup by having famous fashion designers work their magic on AMC cars. The first model to get the fashion treatment was the Hornet Sportabout wagon, with a special Gucci edition that became available for 1972. Later that same year, Pierre Cardin's Javelin was introduced. The Cardin Javelin arrived midway through the '72 model year as an interior option package. The designer had submitted as many as 10 proposals to AMC, and the chosen selection was a black interior with a wild multi-hued stripe of silver, white, red and purple that grooved across the seats, touched the door panels and continued onto the headliner. "People should feel like they're sitting in a living room rather than a machine," the designer was quoted in ads introducing his eponymous Javelin. In a press release, AMC said, "Cardin takes an ultra-modern abstract approach to his interior design." The Cardin interior option package was available with specific exterior colors: Snow White, Stardust Silver, Trans Am Red, and Wild Plum. For the '73 model year, Diamond Blue was a new exterior color option. The Pierre Cardin option was only $85 and was offered exclusively on the Javelin SST, although it's reported that the Pierre Cardin option also appeared on a handful of Javelin AMX models. For 1973, you could officially get a Pierre Cardin Javelin AMX. A total of 4,152 were built over the two model years. AMC's next fashion special was the Matador coupe, but the automaker tapped Oleg Cassini for that gig. Pierre Cardin was not finished with the automobile business, though. In 1975, he put his touch on the Sbarro Stash, an obscure supercar based on the SV1, with the result displayed at the Paris auto show. The designer next customized a run of early-'80s Cadillac Eldorados, and this time the treatment extended beyond the interior. A redesigned front end featured hidden headlights behind a full-width horizontal-car grille but unfortunately made the already-considerable front overhang even longer; the rear treatment was similarly modified with the factory vertical taillights replaced with horizontal units.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
