Cadillac teases two new V-Series prototypes at the Detroit Grand Prix

We told you earlier this week that there would be more to come from Cadillac's V-Series of performance vehicles following the introduction of the brand's CT4-V and CT5-V performance sedans. We just didn't expect it to come quite so soon. Cadillac surprised attendees of the 2019 Detroit Grand Prix as two new prototypes took to the track for what we figure must have been demonstration laps in between other official race events. A CT4-based machine wearing funky blue camouflage joined a red-hued CT5-based prototype on the track, with driving duties split between Mark Reuss, president of General Motors, and Ken Morris, vice president of Product. Cadillac CT4 V-Series prototype View 3 Photos Exactly what's powering these prototypes is still a mystery, but we have our suspicions that these two beasts are putting down a lot more power than the 320-horsepower CT4-V and 355-hp CT5-V that underwhelmed enthusiasts earlier this week. We wouldn't be surprised if there was a version of Cadillac's twin-turbo Blackwing V8 engine under the hood of this V-badged CT5 prototype. Cadillac is being coy with further details, saying only that these two vehicles "represent the next step in Cadillac's V-Series performance legacy." So we'll just have to wait for now. But in the meantime, feel free to peruse the images above and speculate in the comments below.

Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.

Cadillac is doing a 'second installment' of the CT6-V for $92,790

After being all but certain the Cadillac CT6 would begin pushing American daisies June 1, the brand said "the CT6 was never meant to be fully on the chopping block." The same day we got that news, Cadillac began taking pre-orders for the CT6-V. Limited to 275 units and costing $88,790 after destination, orders came in so quickly that order books closed only hours later. Turns out the phrase "275 pre-order slots" was another slight miscommunication. Cadillac has announced continued production of the CT6-V, this time costing $92,790. In February, Cadillac Society confirmed with the automaker that the 275 figure only applied to pre-orders. It isn't clear how many CT6-Vs will be built in what the brand calls the "second installment," but it is clear that buyers who didn't get in early will pay more. Cars Direct was privy to a letter sent to dealers that said pre-order buyers "were rewarded with a special introductory offer by quickly raising their hand." Those slow on the draw have hopefully used the extra time to fish another $4,000 from their pockets. The elevated price buys the same car that was $88,790 two months ago - nothing has changed but the bottom line. The new MSRP puts more distance between the hot CT6-V and the $89,290 CTS-V. Conversely, the CT6-V with a Blackwing V8 beating 550 horsepower and 627 pound-feet of torque is now just $4,000 less than the coming Platinum V8 trim, which costs $96,790. That Platinum version gets a detuned Blacking putting out 500 hp and 553 lb-ft. The vague phrase "second installment" phrase makes us think Cadillac's not committing to a number so it can cap production at will depending on how this more expensive go-round fares. Still, it's good news for anyone who wanted the sedan new and didn't hit the buzzer quickly enough in January. As if all that weren't surprising enough, GM Authority reported that there's a second-gen CT6 in development. The outlet's sources say the new sedan will move to GM's VSS-R platform, the modular architecture that will replace both the Alpha and Omega platforms. The platform initialism stands for Vehicle Set Strategy - Rear-wheel drive. The car even has a codename: 7ESL, where 7 represents the architecture, E the segment, S the sedan body style, and L the Cadillac brand. Looks like the CT6 will be nothing but surprises this year.
