Cadillac teases production ELR ahead of Detroit Auto Show

General Motors has just confirmed that the 2014 Cadillac ELR will make its official debut next month at the 2013 Detroit Auto Show. We've already seen the ELR testing earlier this year using the same range-extended electric drive system as the Chevrolet Volt, and based on the shadowy image above, we're happy to see that the coupe's styling has stayed pretty true to 2009 Converj Concept.
The two-door ELR will be built alongside the Volt at GM's Detroit-Hamtramck plant starting later next year. Aside from this info, Cadillac has remained tight-lipped on the specific details of the car. But all that will all change on January 15.
Until then, all we have to offer you is the press release posted after the jump.

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."

Hotter Cadillac CT5-V could use the CTS-V's 6.2-liter V8

Cadillac is in the final stages of testing the high-performance variant of the CT5, prototypes are racking up miles all over the world, and a recent report sheds light on the engine screaming between its punched-out fenders. It's a V8, to no one's surprise, but it's not the twin-turbocharged, 4.2-liter unit many believed the sedan would use. Sources familiar with Cadillac's product plan told Car & Driver the hotter CT5 — whose name hasn't been revealed yet — will receive an updated version of the supercharged 6.2-liter V8 that powered the mighty CTS-V. It developed 640 horsepower in the firm's last German-bashing super-sedan, though where engineers will peg the CT5's output remains to be seen. It will roast the rear tires through a paddle-shifted automatic transmission. The publication explained Cadillac chose the 6.2-liter because it's more compact than the 4.2-liter Blackwing engine it developed for the CT6. The former features a pushrod design, while the latter gets twin overhead cams that make it taller and wider. The CT5 is a new model, but its Alpha platform is older than Cadillac's newest V8. Cadillac hasn't announced what will power the flagship CT5. The model is tentatively due out in showrooms before the end of 2020, so we expect to learn more about it in the coming months. Seeing it in the metal for the first time during the 2020 Detroit Auto Show in June isn't entirely out of the question. What's next? If the report is accurate, the much-hyped Blackwing may end up being an orphan engine. It was developed specifically for the Cadillac brand, and inaugurated by the CT6-V that recently went out of production. The many rumors claiming General Motors will put the engine in other models to recoup its investment are falling like dominoes. It won't fit in the CT5, so there's no reason to believe it will end up in the smaller CT4; its flagship version will likely arrive with a twin-turbocharged, 3.6-liter V6 borrowed from the ATS-V. An earlier report claims the next-generation Escalade won't use the Blackwing, either, because making it fit would cost too much. Looking beyond Cadillac, the only General Motors-owned brand that could use the Blackwing is Chevrolet, since we can't imagine the GMC Yukon will get it if the Escalade doesn't. The Tahoe/Suburban duo is off the table, too.
