A flagship’s function is to face as the head of an automaker’s biggest efforts to this point. It has to supply one of the best of what the automaker itself affords, with value not factoring as a lot into the equation. The Cadillac CT6… form of falls into that class. (Some say it is the Escalade, however that is up for debate.)

Certainly, the CT6 scoops up most of Cadillac’s newest expertise, whether or not it is the semi-autonomous Tremendous Cruise, four-wheel steering or, within the case of this assessment, a giant ol’ plug-in hybrid battery. However this full-size luxurious sedan is not precisely constructed to compete with the flagships from Audi, BMW and Mercedes-Benz.

As a substitute, the CT6 carves its personal path. By chopping again in small however perceptible methods, the CT6 presents itself as extra of a worth purchase — particularly so with the plug-in hybrid. It brings quite a bit to the desk, and whereas it could not have the wow issue of its dearer rivals, it is nonetheless a compelling automotive.

Underneath the radar, in and out

Cadillac’s largest sedan is decidedly delicate. There aren’t any flashy exterior cues, just a few attention-grabbing shapes within the headlights (the operating lights resemble teardrop jail tattoos — in a great way) and a few intelligent chrome accents on the taillights out again. I am not a fan of the reverse lights being tucked into the underside of the bumper, which isn’t simple for taller automobiles to see. Cadillac additionally has this factor the place the scale of the wheels is barely barely proportional to the large physique round it — I famous this in my CTS V-Sport assessment from final 12 months, as effectively.

The inside would not pack S-Class high quality, nevertheless it’s good. The CT6 is a big luxurious automotive, so area is ample for each entrance and rear occupants, and the fortunate ones within the again get to get pleasure from a typical rear leisure system. My tester’s black-on-black-on-black-on-black leather-based inside feels cavernous, and supplies on the sprint and heart console solely really feel barely worthy of the $70,000-plus price ticket. That is the place the automotive falters most towards its opponents.

Gentle pouring in via the massive home windows and twin panoramic moonroof assist break up the inside’s darkness, however a excessive rear beltline eats into visibility via the rearview mirror. And talking of mirrors, can anyone inform Cadillac to surrender on the tiny-side-mirror development? For such a giant automotive, the CT6 has hilariously small aspect mirrors, that are simply plain dangerous for rearward visibility.

The PHEV system’s battery lives within the trunk, so as an alternative of the usual CT6’s 15 cubic ft, you are caught making do with simply 11. That limits what you possibly can put within the trunk, however golf golf equipment and suitcases will nonetheless match, simply not . Should you’re not planning any lengthy journeys, it handles weekly grocery duties simply tremendous.

Heck, you do not even get 4 tailpipes on this dangerous boy, simply the 2. It is delicate.

Hush, hush

Whereas it could lack the visible panache of its dearer tablemates, the CT6 Plug-In does provide a quiet experience. Cadillac’s noise isolation is stable, and when working on EV energy alone, the cabin stays hushed. A few of that credit score goes to the Goodyear Eagle Sport all-season tires, which have thick sidewalls (235/50 entrance, 265/45 rear) that do not get noisy till the higher finish of freeway speeds.

The CT6 drives on the European aspect of soppy, which is to say it is not pillow-soft like a Lexus, however nearer to the agency, composed feeling you get from German govt sedans. Potholes and different street hazards are simply dispatched and solely barely translated to the cabin, once more partly owing to the thicker soles on the Caddy’s sneakers.

The plug-in powertrain places out a commendable 335 horsepower and 432 pound-feet of torque. It will hustle properly on electrical energy alone, and retains the momentum when the two.Zero-liter four-cylinder fuel engine kicks in. The transmission is a fancy mess of planetary gears and clutches with a number of variable and stuck gear ratios, however in layman’s phrases, it mainly acts like a CVT. It sometimes reveals bizarre tendencies: typically the fuel engine kicks in and instantly revs excessive and loud. And whenever you’re working largely on gas-engine energy, you get a prolonged delay between pushing the pedal and feeling the acceleration.

If you wish to maximize your effectivity, slapping the shifter to M begins up a four-stage regenerative braking system. You’ll be able to “downshift” via more and more sturdy ranges of brake regen to cease easily, or you possibly can put it proper into its strongest setting and get 99 p.c of the way in which to one-pedal driving. Frequent use of the regenerative braking will not add a ton of vary, however each little bit helps, and attempting to one-pedal down the street makes issues a bit extra thrilling when you’re a raging nerd like I’m.

The CT6 Plug-In’s sizable battery offers it a 31-mile EV vary that is completely believable in temperate climates. However that vary was nearer to 25-27 miles once I examined it in a cold Michigan February, and you may lose a few mile of vary in a single day if the automotive is not plugged in. The CT6 will do a formidable 78 mph on electrons alone, however that massive battery additionally lends to massive cost occasions — almost four.5 hours on a Degree 2 charger. Over a pair hundred miles of combined use, displayed MPG hovered round 31. There is a mode to carry the battery cost at a given stage whereas driving — like when you’re on the freeway and wish to save your electrical energy for around-town stuff — nevertheless it must be chosen every time the automotive begins, so remember.

It won’t be a driver’s automotive, per se, nevertheless it’s nonetheless not too shabby when the going will get spicy.

Tech that could possibly be higher

Here is the true bummer — you possibly can’t get Cadillac’s wonderful semi-autonomous Tremendous Cruise system with the CT6 Plug-In. Tremendous Cruise works together with the CT6’s four-wheel-steering system, which is not fitted to this mannequin because of PHEV packaging constraints. So that you’re caught with extra conventional driver-assist methods.

These methods work tremendous, although. Adaptive cruise management is clean, however the ahead collision warning is a bit sensitive even on its least anticipatory setting, particularly whenever you’re attempting to maximise brake regeneration.

The CT6 Plug-In additionally lacks the newest iteration of Cadillac’s CUE infotainment system. It is nonetheless a lot highly effective, with a brand new slate of related apps and a typical 4G LTE Wi-Fi hotspot. However since that is the corporate’s flagship, Cadillac ought to have introduced its new system over right here. I do like the additional hybrid-only pages within the infotainment system, which lets me plot out charging methods and see how the facility is being routed in actual time. Apple CarPlay and Android Auto are right here, too, and so they’re pretty much as good as normal.

The configurable gauge cluster affords totally different layouts, all of which try to supply up as a lot simultaneous info as potential, which is nice for stopping distracting appears to be like on the infotainment display. The USB ports cost tremendous and are ample in amount, though the under-seat location of these ports within the rear aren’t instantly apparent, and would possibly trigger consternation whenever you’re driving three-up within the again.

How laborious may it have been to place the brand new CUE in right here?

How I might spec it

The CT6 Plug-In is barely out there in a single specification with a complete bunch of normal gear, so I suppose that is how I might spec it, as a result of I do not actually have a alternative. If I had the choice, I might add Tremendous Cruise for just a few thousand further. However I can not. Customary gear contains ahead and reverse autobrake, a panoramic moonroof, a head-up show, a 360-degree digicam system and parking sensors.

All the way down to brass tacks

Cadillac’s big-boy PHEV will set you again a cool $76,090 together with $995 for vacation spot. That sounds costly till you notice comparably outfitted BMW 730e iPerformance prices almost $15,000 extra. The outgoing Mercedes-Benz S550e — a refreshed model is coming quickly — has a good bigger worth disparity. The Cadillac’s closest competitor is the 2018 Lexus LS 500h, however even that one remains to be about $four,000 dearer. Not one of the aforementioned automobiles provide the identical stage of normal gear, both.

So the CT6 Plug-In is, the truth is, a worth proposition. Certain, it could not be capable of maintain a candle to the 7 Sequence’ driving dynamics, it is nowhere close to as fancy because the S-Class and nowhere close to as fairly because the Lexus. However when you’re prepared to just accept these sacrifices, you will find yourself with a delicate plug-in hybrid that gives wonderful vary, tons of inside area and a experience that is fairly darn Germanic. If that is your purchasing phase, the CT6 Plug-In is certainly value your time.
