2016 Cadillac CTS-V: In-Depth with the Four-Door Corvette


a good 640-hp Nürburgring-eating CTS-V isn’t a good natural descendant of your house involving Cadillac. your current king of cush plus the caesar associated with geezers feel right after none too concerned inside steering fidelity, roll gradients, lateral grip, and also the like. these types of were figuratively IN ADDITION TO literally foreign concepts, Just as your modern luxury car—as sharp with clipping the apex Just like This can be comfortable to the highway—is largely an European conceit.

Cadillac finally turned the corner (without hideous squealing) throughout 2003 within it is initial CTS. Ever since the then, your name have been hellbent from topping the German rivals. your current 2016 CTS-V, that will intended its debut in this year’s Detroit auto show, is actually Cadillac’s Best chance yet for you to do so.

We’ve already witnessed the third-generation CTS top your Mercedes-Benz E-class and also the BMW 5-series (albeit even though moving second place towards the Audi A6). Starting from the same cornerstone, your own new CTS-V In the event that have Germany’s three big gunslingers—Audi RS, BMW M, IN ADDITION TO Mercedes-AMG—reaching nervously for the lederhosen.

The CTS-V provides always been an kind regarding four-door Chevy Corvette. your own new V ties ones Vette connection even tighter within the engine lifted from the ballistic Corvette Z06. your engine is usually and so lightly altered for Cadillac duty That this company could possibly help have called your car your own CTS-V06.


your own 6.2-liter supercharged V-8 retains the LT4 moniker AND packs your Z06’s forged aluminum pistons, powder-metal forged connecting rods, titanium intake valves, AND ALSO the Eaton blower pushing 1.7 liters associated with air per rotation. Aside through the intake AND exhaust arrangements, your biggest difference between your current Corvette AS WELL AS CTS-V engines may be the lubrication system. on the Corvette, your low hood as well as the height of an supercharger dictate a dry sump AND ALSO remote oil reservoir. your own relatively tall Cadillac doesn’t have ones same hood-height issues, consequently oil starvation is actually maintained with bay with high-g corners coming from a deep sump, reducing complexity AND ALSO weight.

Given your own differences throughout the cooling systems IN ADDITION TO how the only two cars breathe (plus ones always-lurking horsepower hierarchy dictated by name management), the many Z06’s 650 horsepower AS WELL AS 650 pound-feet of torque won't materialize for the Cadillac. Instead, your CTS-V will be rated on 640 horsepower AND ALSO 630 pound-feet. we project a great zero-to-60 blitz involving 3.7 just a few seconds en route in order to a good 12.0-second quarter-mile ET. anybody figures would essentially match your own BMW M5’s, but lag behind anybody of a four-wheel-drive Mercedes-Benz E63 AMG AND Audi RS7 from the quarter to be able to half of any second.

The V’s top speed stands to help possibly be even additional impressive. CTS chief engineer Tony Roma was coy at first, saying singular The item his department aims pertaining to “a big number,” but he eventually let with The item they’re hoping your car may exceed 200 mph. at MY OWN interview, your current closest we got to help the CTS-V throughout motion \'m firing your small-block V-8 engine. it\'s seven cylinders came for you to life that has a rabid bark The item ricocheted off your coved walls connected with MY photo studio earlier ones 6.2-liter settled in the gravelly idle, easily AND loud. your current sound is actually Just like extraordinary Equally That is assertive, though your own neighbors will probably think otherwise Whenever anyone leave the driveway from six to eight a.m. pertaining to anybody occasions, you’ll want to help beginning your current car inside tour mode, that will retains the muffler-bypass valves closed for you to quiet ones snarl.


GM’s own 8L90 eight-speed automatic is the single transmission, a great move It ­disappoints but inside zero way ­surprises us. Roma gives the conciliatory maybe: “If there’s enough fervor with the enthusiast community, we’ll carry doing a good manual.” Don’t hold the breath. by the forthcoming ATS-V to help squat toe-to-toe because of the BMW M3, your own CTS-V now assumes a good narrower role. There can be simply no coupe or even wagon, and the price swells by $65,825 for the 2014 CTS-V sedan for you to roughly $85,000.

The chassis follows ones usual formula pertaining to bringing in sedans sportier, just like stiffer springs, larger anti-roll bars, AS WELL AS firmer bushings. in the front suspension, employing two lower links instead associated with solitary ­control arm quickens steering response. Magnetorheological dampers tend to be stand­ard, In the same way is actually the electronically controlled limited-slip differential borrowed because of the CTS Vsport IN ADDITION TO modified having a heat exchanger connected towards transmission’s cooling circuit.

Iron brake discs mounted at aluminum hats measure 15.4 inches up front AND ALSO 14.4 on the rear. They’re squeezed by six- AS WELL AS four-piston calipers, respectively, borrowed by the Camaro Z/28’s carbon-ceramic brake package. your rear discs are generally so large, they’d always be verboten for the World Challenge sequence through which the latest CTS-V coupe competes. your own brakes definitely won’t shed heat quite just like carbon discs, but your own additional surface location of any massive rotors means ones front discs operate 200 degrees Fahrenheit cooler whilst working in comparison with the individual of a outgoing car.


Michelin tailored your own Pilot Super Sport tires—265/35-19 front AS WELL AS 295/30-19 rear—specifically for its car, plus the tires come out involving the bespoke mold. 3 additional tread rubber compounds balance your contradictory goals regarding extending tire life IN ADDITION TO maximizing cornering grip.

The CTS-V can be individual car in individual suspension. You will find simply no upgrades, no optional big wheels, AND not any add-on carbon-ceramic brakes. your singular chassis-related selection comes lower to be able to wheel finish. “These cars usually are built to possibly be your boutique offering,” Roma explains. “We feel just like good can be good, so we’ve tuned the chassis IN ADDITION TO people get ones good stuff. people don’t have to check on your own track-package box. this is the track package.”

Those which do venture on top of road circuits can benefit because of the CTS-V’s first MAKE USE OF of any Performance Traction Management (PTM) system. primary demonstrated to the 2010 Corvette ZR1 AS WELL AS right now offered with most Corvettes, PTM’s several modes—from wet to race—progressively loosen your current stability-control system’s oversight. Track rats additionally will certainly Record their exploits towards optional Performance information Recorder, that overlays vehicle facts from a online video media captured by an camera mounted ahead of any rearview mirror.

If the CTS Vsport will be any kind of indication, the full-blown V Should deliver several of a purest steering was out there—not simply among the competition, but with most connected with luxuryland. because of its Cadillac team, it’s the merchandise involving philosophy a lot more than a engineering challenge. “If people shop at the fundamental parts This quite a few THE competitors have inside their cars, you’ll obtain architectural components that you can would put throughout an car to get what we call good steering feel,” Roma says. “So When my partner and i go drive ones resulting car, numerous times when i go, ‘Whoa, This is and so isolated.’ Clearly several MY OWN competitors favor ride AND isolation since there can be a trade-off to help always be made.”


The CTS lineup benefits from an electric power-steering motor that connects to the rack via a belt rather than a gear or a recirculating-ball system. When the car passes over a pavement imperfection, there’s enough compliance in the belt for the jostle at the tires to reach the steering wheel without being damped out by the assist motor’s inertia. In the V, the steering supposedly becomes even more direct when the PTM system is set to its highest levels, switching off the electric power steering’s damping and self-centering functions.

The V series looks the part of a factory-tuned street racer with a louvered hole punched in the carbon-fiber hood, wider front fenders, and a slightly lower stance. The fender vents, originally requested by the design team, were only approved on the condition that they be functional. While they aren’t critically important, the vents do connect to the engine bay, providing an escape for underhood heat. The car we photographed wears the optional carbon-fiber package with a longer front splitter, a taller spoiler, a carbon rear diffuser, and Gurney flaps ahead of the front wheel wells. The package doesn’t reduce weight by any quantifiable measure, but it does reduce aerodynamic lift, aiding the CTS-V’s high-speed handling balance. Unfortunately, the additional downforce imposes higher drag, so cars equipped with this option aren’t likely to reach 200 mph. While the exposed weave gives this $85,000 Cadillac a we-made-it-for-SEMA vibe, the quality at least lives up to the price. Look closely and you’ll see that the carbon fiber is laid at an angle and book-matched so that the weave creates a “V” at the center of the car. Whether you order the carbon package or not, the CTS-V comes with a new curb-view video system that uses two downward-facing cameras mounted along the upper edge of the lower grille to help drivers nestle up to a curb without scrunching the lower fascia. It’s a useful feature that should be shared with the Corvette team in exchange for its LT4 V-8.

The V-specific weight-saving measures are few and limited, but the Alpha platform on which the CTS is based has a lean bone structure to start with. Cadillac claims a weight of 4145 pounds for the CTS-V, a drop of roughly 100 pounds from the previous car. And while 4150 pounds isn’t light, it is less than the 4300-pound M5, the 4400-pound E63 AMG, and the 4500-pound RS7.

Less weight is one advantage Cadillac has never held in previous comparisons. We’ll soon know if the claim holds up, and more importantly, if Cadillac’s long-running pursuit of Germany’s ultimate sports sedans has finally paid off.
