Serene and Mean: 2018 Cadillac CT6 Plug-In Test Drive

It’s an interesting bit of trivia that the the first hybrid vehicle was invented by Dr. Ferdinand Porsche, over a century ago. But it’s only in the last two decades that we’ve seen them catch on, and in that time the technology has helped revolutionize transportation. Just look at the amazing MPGe — or miles per gallon equivalent — numbers some automakers have been able to achieve. Starting out in economy cars, hybrid systems can now be found in everything from SUVs to full-size sedans — like the 2018 Cadillac CT6 Plug-In you see here. Years ago, buyers would’ve scoffed at the idea of a hybrid luxury sedan like this, but in 2018 it’s a reality, and after putting over 1000 miles on this car, I can tell you from experience that it makes perfect sense.

Cadillac has always been at the forefront of American luxury design, and since their inception in 1902, its goal has been to deliver an automotive experience that others would seek to emulate. And after 100 years in the business, it’s good to see that philosophy is alive and well in the new 2018 CT6 Plug-In. Bold design and sleek sheet-metal are combined to create a well-portioned shape for the luxury sedan of the 21st century. The large front grille and lower front callouts utilize brushed accents for a soft yet aggressive look, and sculpted vertical LED headlamps flank the large grille and flow into the front fenders, above the LED auxiliary driving lights.

Along side, embossed Cadillac shields reside in the front fenders, while large windows with brushed trim help to frame the CT6s low beltline. A set of 18-inch Ultra Bright Machined rims with a sterling silver finish fill out the wheel-wells, and out back, LED rear tail lamps are accentuated by the further use of brushed trim. The CT6 does not resort to over-the-top gimmicks, but instead relies on a smart shape with minor contrasting accents to set it apart from others in the segment.

The 16-way adjustable leather seats with heat and ventilation make the Cadillac CT6 a very easy vehicle to get comfy in. At 6’4”/240 pounds, not only did I find them extremely comfortable, but thanks to the great support, I managed an over 500-mile day without a hint of fatigue. As a whole the cabin is soft, meaning the materials used are easy on the eyes with great touch feel. Gone are the glossy, piano-black accents Cadillac used to be known for. Instead, we’re treated to rich wood, textured inserts, and beautifully trimmed leather surfaces. Rear seat room was beyond ample, and our CT6 even came equipped with the rear seat infotainment system with retracting 10-inch screens and built-in 4G LTE Wi-Fi.

Heated surfaces are offered in the rear as well, as are retractable sunshades for both the rear doors and rear window. A large panoramic glass roof also excels at keeping the cabin airy.

Comfort aside, the 2018 CT6 Plug-in is loaded with interior technology. The 12-inch color gauge cluster, for instance, can be configured in a variety of ways to showcase speed, electronic battery range, fuel, and much more. The colors are soft, and when combined with the HUD finding information when you need it is a snap. An additional 10-inch color touchscreen is positioned in the center console, and allows one access to the infotainment system, navigation, apps, vehicle settings, Apple CarPlay and more. It must also be said that the cabin is remarkably quiet, be it around town or on the highway. As this is a plug-in, trunk space has been compromised to the tune of 11 cubic-feet overall.

2018 Cadillac CT6 Plug-In RWD Performance

If you’ve ever been behind the wheel of a hybrid or electric vehicle, then you know the application of torque when you put your foot down is instantaneous. There’s no lag in initial power as with a combustion engine, and instead a simple WHOOSH of power that sends you forward is present. As a plug-in, the CT6 utilizes both a 2.0-liter turbocharged 4-cylinder-gas engine, along with a multi-drive electronic drive system. Working together that means a total combined power output of 335 horsepower and 432 lb-ft of torque. The transmission is what Cadillac calls an Electric Variable Transmission (EVT), but it’s basically a CVT (continuously variable transmission) with a different name.

The CT6 Plug-In also treats drivers to three different drive modes – Tour, Sport and Hold. Tour offers a balance between comfort and sport while optimizing EV range. Sport stiffens up the steering feel while enhancing acceleration and Hold stores battery life for later use. Speaking of which, the CT6 can be plugged in to deliver up to 31 miles of full-EV driving on a single charge. What’s even more impressive is that this 4,498-pound full-size sedan is actually quite quick. We’re talking about a total combined mileage rating of 62 MPGe, a zero-to-60 time just 5.2-seconds, and a top speed of over 150 mph. In my book, those numbers are pretty darn good.

It should be noted that the regenerative braking does take a little getting used to, but once mastered it almost becomes a game in regards to seeing how much energy you can store. Handling on the CT6 is also good with braking bringing the car down with a force that inspires confidence.

2018 Cadillac CT6 Plug-In RWD Overall

It’s not too often that a car surprises me, yet there I was rolling down the Pacific Coast Highway at dusk, getting amazing fuel economy and cruising in almost complete silence. The 2018 Cadillac CT6 Plug-In is an anomaly in the fact that it actually offers fantastic performance that’s actually kept under wraps by the civility of the driving experience. If you want power and handling, it’s all there, but most of the time, I was content to simply cruise in silence. This was a good one folks — I must say that I enjoyed my time with it immensely.
