Cadillac Blackwing models will finally be revealed in February

It's been a little over a year and a half since Cadillac reworked the V line of performance sedans and teased something above its regular V cars. In that time, we've seen camouflaged prototypes and a teaser for a manual shifter with a 3D-printed topper, but hardly anything about specifications. That should all change next month. The company released a teaser announcing the reveal of the Cadillac Blackwing variants of the CT4-V and CT5-V on Feb. 1. The teaser hardly shows anything of the cars except a brief shot of someone shifting, and what sounds like a fairly ferocious V8 exhaust note. Based on prototypes and rumors, we're expecting the CT5-V to use a supercharged 6.2-liter V8, rather than the unique DOHC turbocharged V8 from the CT6-V, and the CT4-V will likely have a turbocharged V6. The CT5-V has also been spied with quite a bit of tire, 305-mm in the rear and 275-mm in the front. Based on these car's similarly powered predecessors, the ATS-V and CTS-V, they should be extremely entertaining. Related Video:

2014 Cadillac ELR leases for $699 a month

Most Autoblog readers thought the $75,000 price tag on the 2014 Cadillac ELR was too high. If you can't swing the MSRP all in one go, how does a lease price of $699 a month sound? That's the amount that Cadillac is offering on the official ELR website, with some caveats, of course. First off, it appears that this lease price is for just for "current owners and lessees of all 1999 or newer GM vehicles." They will also have to pony up $4,999 at signing (all others will need $5,999). Second, the $699-a-month price is for a 39-month lease. Then, of course, "tax, title, license, dealer fees and optional equipment [are] extra" and "each dealer sets own price." Also, it appears that this lease deal is only good until the end of January. Cadillac started shipping the ELR plug-in hybrid coupe to dealers last month. There are two things to note in the fine print. The most surprising is that the payments are based on "a 2014 Cadillac ELR with an MSRP of $76,000." That's $1,000 more than the official MSRP announced in October. Then we get to the real kicker: The lease limits you to a mere 32,500 miles, which is just 833.3 miles a month. Well, 'limit' isn't the exact word, since you can certainly drive more. All you have to do is pay 25 cents per mile for each mile over 32,500. Drive the national average of 13,476 miles in a year? That comes to 43,797 miles over 39 months, which is 11,297 extra miles and an extra $2,824.25.

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."
