General Motors is making a big push for electrified vehicles over the next few years, and its 21st Century technology won't be limited to mass-market Chevrolets. One prime example is GM’s CT6 Plug-In, a gas-electric hybrid luxury flagship sedan from GM’s Cadillac brand. It's the only Cadillac you can buy in North America that isn't made here. The unique nature of this Cadillac means its biggest market isn't the USA — it's China, where the government is pushing electric vehicles hard in an effort to clean up the country’s choking air pollution, and where this PHEV is constructed. Cadillac is currently experiencing a 90% year-over-year sales growth in the People’s Republic versus a 4.6 percent drop in the U.S. over the same period.

The Cadillac CT6 combines a European luxury feel with a bold American design and plug-in technology. Adding together 2 powerful electric motors with a Lithium-ion battery and a high-output 2.0L Turbo 4-cylinder gas engine, this luxury plug-in variant is capable of 31 pure electric miles. The full-size premium sedan is fast for its larger size; it reaches 60mph in 5.2 seconds. Base price is around $75,000 before tax credits and a California State rebate.

The Car Connection's Brandon Turkus says: "The 2019 Cadillac CT6 offers all on paper that a flagship luxury sedan should. It's stylish, a technological leader, and it has one of the industry's most advanced semi-autonomous driver-assist systems. For 2019, it adopts a new twin-turbocharged V-8 engine. As cool as a 550-hp luxury sedan is, the CT6’s tauter, more stylish skin is what you’ll see first. The minor changes offer a timely mid-cycle update––new headlights and taillights and lightly updated fascias––but their cumulative impact is slight. The headlights scowl ahead, and along with the LED ribbons that flank them, complement the wider and slimmer grille. This is a very handsome car."

The CT6 battery comes in a 18.4-kilowatt-hour pack — around the same size as what’s in a Chevrolet Volt — and has enough juice to move the CT6 for about 31 miles on electric power alone. Once the battery is empty, the gas engine provides power to the wheels and electricity to the system to keep you going more than 400 additional miles at an average of 26 mpg. 

Car & Driver says: "Sleek styling and high-tech features help the CT6 shed the Cadillac clichés in an attempt to best its European rivals. A 265-hp turbo 2.0-liter inline-four and eight-speed automatic drive the rear wheels; a 335-hp 3.6-liter V-6 and 404-hp twin-turbo 3.0-liter V-6 have all-wheel drive. A plug-in hybrid boasts up to 31 miles of electric-only range. Onboard 4G LTE Wi-Fi is standard, as is Apple CarPlay and Android Auto. High-end options include a 34-speaker stereo and adaptive cruise control."

The Plug-In takes many of the options available in the Premium Luxury and Luxury configuration and makes them standard. The Driver Awareness and Convenience and the Enhanced Vision and Comfort packages are all standard. The Hybrid comes with 18-inch wheels and is only available in rear-wheel drive. Due to the large battery pack, you lose some trunk volume.

Reviewer Calvin Kim: “Under the hood, the CT6's segment-straddling identity is apparent. Turbocharged four-cylinder power is standard, and it's the same engine that's featured in the Cadillac's midsize CTS. You won't find that combination in any of its German competitors. But there's no doubt that the CT6 reaches new heights of luxury relative to its midsize brethren. Throw in generous rear passenger accommodations, top-shelf interior trimmings and a competitive starting price, and the CT6 becomes a legitimate challenger to the traditional leaders.”

Cadillac says the front seat comfort of its CT6 is “tailored for Ultimate Luxury. Sculpted, contoured and wrapped in rich cut-and-sewn leather with heating and ventilation. These available seats are designed to indulge you.”

Cadillac on the car’s quiet acoustics: “Of the many innovations that make the interior quiet, none is more important than an advanced body structure – a frame constructed using revolutionary alloys and fusion technologies. This effect is enhanced when driving electric.”

Cadillac on the car’s handcrafted materials: “Unmatched attention to detail. A curation of authentic, natural materials like rich perforated leathers, exotic wood trims and Galvano chrome accents are fit and tailored with handcrafted precision.”

Cadillac on the exterior design: “Strength and style are complemented by a powerful stance and iconic vertical lighting. Lines, curves and sweeping planes seamlessly mesh to create a look that is both hard to resist and impossible to mistake.”

Calvin Kim: "If you've decided to trade up from a smaller plug-in-hybrid to something in the luxury field, and you're still dedicated to the idea of driving something with an electrified powertrain, the CT6 Plug-In is a reasonable choice. It's a good step up from a Chevy Volt or Hyundai Sonata Plug-in Hybrid."
