Cadillac XT4-V on the way?

An anonymous photographer sent Cadillac Society two tightly cropped images of an XT4 crossover wearing two surprising badges. On the right, above the taillight, there's a 2.7 badge, In the lower right corner there's a V Series badge — the full-fat, multicolored V badge, not the monochrome V-Sport version. The images — assuming they're real — elicit more questions and no answers, the first being, is this the XT4 V-Sport that's been rumored since last October? Back then, GM Authority discovered front and rear images of such a vehicle hiding in plain sight, on a Cadillac site landing page. The backside of a thick-hipped XT4 is graced with the old V-Sport badge. We know the carmaker has split its V Series cars into two tiers, the lower intended to be less intimidating than before, the upper tier the continuation of the mongo V Series cars we've known and loved. The hints have been that the entry level will be called V Series, while the upper level takes the name "Blackwing," after the name of Cadillac's new 4.2-liter, twin-turbo V8 engine. With Mark Reuss himself having said, "We got rid of all the V-Sports," this supposed XT4-V offers more proof that V Series effectively represents a new V-Sport line. The only cosmetic giveaways to increased performance we can see are a carbon fiber trim in the license plate area, and an exhaust treatment similar to that on the recently introduced CT4-V. We're not certain what the 2.7 badge means for V branding on crossovers. The standard XT4 wears a 2.0 badge on the tailgate, representing its 2.0-liter four-cylinder with 237 horsepower and 258 pound-feet of torque. The XT5 gets a number, too, but the XT6 does not. GM's 2.7-liter four cylinder with 311 hp and 348 lb-ft first showed up in the Chevy Silverado, will get 320 hp and 369 lb-ft in the coming CT4-V, and has been predicted for the XT4-V. However, V cars — both Sport and Series — have never worn displacement badges. The new CT4-V and CT5-V go without numerical identifiers on their decklids. If there is an XT4-V on the way this year, we only have a few months before we see it and get some answers.

Hottest Cadillac CT4-V and CT5-V rumored to offer manual transmissions

We recently received one large detail to fill in the picture of the hottest versions of the Cadillac CT4-V and CT5-V, the sedans maybe or maybe not called Blackwing. As you know, due to a platform switch caused by cost cutting at parent GM, the 4.2-liter twin-turbo Blackwing V8 won't figure in the equation because it won't fit in the engine bay of either sedan. The new, gone-too-soon engine is too wide and too tall. The hottest V models will turn to stalwarts in the range, the CT4-V appearing to get the 3.6-liter twin-turbo V6 used in the departed ATS-V, the CT5-V working with the 6.2-liter supercharged V8 also put to use in the Chevrolet Camaro ZL1 and C7 Corvette Z06. But all of this could mean good news for three-pedal enthusiasts; both engines have been paired with manual transmissions previously, and Muscle Cars & Trucks says both of the coming flagship V models will get manual transmissions. We've expected a manual in the CT4-V. Not only did GM President Mark Reuss say, "Cadillac will make manuals in V-Series" during the launch of the milder V variants, but spy video of the CT4-V from last summer captured a camouflaged CT4-V looking and acting like a car with a manual gearbox. However, no one surmised that the CT5-V would get a manual, too. None of the bigger sedan's competition is sold with a stick shift, and the retired CTS-V with the same 6.2-liter supercharged V8 was only sold with an eight-speed automatic, while just one aisle over the Camaro ZL1 offered a six-speed manual and the Corvette Z06 a seven-speed manual. The last time Cadillac put a row-your-own in the midsize luxury scorcher was the second-gen CTS-V — the one that came in a wagon bodystyle, too — which paired a supercharged LS9 V8 derived from the C6 Corvette ZR1 and a six-speed Tremec manual. MCT doesn't cite any sources, so take this as rumor for now. It's possible to read Reuss' statement in line with this rumor, though. The assumption has been that the plural "manuals" referred to multiple stick shifts going into multiple CT4-V sedans, whereas he could have meant there will be two manual-equipped sedans in the V-Series range. We'll hope for the best and see what pops out of the transmission tunnels on both sedans when they debut later this year. Related Video:

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
