The Cadillac CT6 is the all-new flagship for GM’s luxury brand. Presenting a level of engineering and technology not seen before in a Cadillac product, the CT6 offers a compelling alternative to Europe’s finest luxury models.

Pricing and Equipment

The 2017 Cadillac CT6 is available in CT6 (Base), Luxury, Premium Luxury, and Platinum trims. Rear-wheel drive is standard; all-wheel drive is available.

Three engine choices are available. A turbocharged 2.0-liter four-cylinder engine making 265 horsepower and 295 pound-feet of torque is standard on base and Luxury rear-wheel drive models. A 3.6-liter V6 engine producing 335 horsepower and 284 pound-feet of torque is standard across the entire all-wheel drive range.

Also available with the Luxury, Premium Luxury, and Platinum models is a twin-turbo 3.0-liter V6 engine making 404 horsepower and 400 pound-feet of torque. All three engines are paired with an eight-speed automatic transmission.

Introduced in late 2016, the 2017 model arrives unchanged except for a pair of new exterior color choices. A plug-in hybrid variant arrives later in the model year.

  • The standard rear-wheel drive 2017 CT6 starts at $54,490. Choose all-wheel drive and your price rises to $56,490. This model makes an EPA-estimated 22 mpg in the city and 30 mpg on the highway.
  • The Luxury model starts at $61,390. This vehicle makes an EPA-estimated 18 mpg in the city and 27 mpg on the highway. Cadillac prices the Premium Luxury model from $64,590 and the Platinum edition from $84,490.
  • Choose the available twin-turbo V6 and that’s a $4,000 upgrade where available. Equipped models make an EPA-estimated 18 mpg in the city and 26 mpg on the highway.

Various upgrades, including packages, are available depending on the trim. The $2,950 Driver Awareness and Convenience package brings in features like front pedestrian detection, blind spot monitoring, rear cross-traffic alert, a panoramic power sunroof, navigation, and heated front seats. The Active Chassis package adds magnetic ride control and 20-inch wheels. (Prices do not reflect a $995 destination charge.)

Performance Pros

Cadillac CT6
  • Who needs a V8 when you have access to a twin-turbo V6 producing outrageous power? We knew the new engine was potent, but that’s not all: because of Cadillac’s weight-reducing efforts, it has barely over two tons of mass to move. We don't think you'll wish for a V8 when you get behind the wheel of this twin-turbo model.
  • Our reviewers sang praises over the CT6’s “grippy” handling, especially in models powered by the turbo four. At the same time, they realize more power is needed and say the rear-steer system is helpful with the larger engines.

Performance Cons

  • In a bid to offer something for everyone, the turbo four-cylinder engine found in the compact ATS is the base engine for the CT6. While we certainly can understand providing an efficient base engine, we think most customers will instead set their eyes on either V6 in an effort to find power better matched to this large sedan.

Interior Pros

Cadillac CT6
  • Tall people will find the CT6 roomy, front and back. Further, our reviewers noted that two rear passengers will find more room back there than up front up.
  • The trunk measures 15.3 cubic feet, which is smaller than the XTS. Yet, there is enough room to hold sufficient luggage for four for a long weekend getaway. And when you need to carry a long item, such as a lamp, a pass through to the cabin is present.
  • The available rear camera mirror takes some getting used to, but once you do, you’ll appreciate the expanded vantage point it provides.
  • Created exclusively for the Cadillac CT6, the 34-speaker Bose Panaray audio system, which is standard in the Platinum trim, should appeal to audiophiles. It supplies a level of clarity and precision that other top-shelf systems provide.

Interior Cons

  • We like the fit and finish of the CT6’s interior. We also think Cadillac could have gone for the wow factor regularly offered by competitors such as Audi and Mercedes-Benz. In short, our reviewers thought the aesthetics could have been warmer.

The Most Pleasant Surprise

Although not quite the size of the flagships presented by its top competitors, the CT6 offers a very reasonable starting price. Not many models in this segment begin in the $50,000 range and offer what you will discover in the CT6.

The Least Pleasant Surprise

The latest version of the CUE (Cadillac User Experience) infotainment system is present, but we’re still not keen on what is offered. Like us, you may find yourself using Android Auto or Apple Car Play instead.

The Bottom Line

In the CT6, Cadillac has thrown down the gauntlet, serving notice to Mercedes-Benz, BMW, Audi, and Lexus that it intends to go after the same customers these automakers prize. Quite easily, the CT6 is the best Cadillac we’ve seen in decades, a model offered with multiple powertrain and drivetrain choices in an effort to reach a variety of luxury sedan shoppers.
