Gone too Soon: 2018 Cadillac CT6 3.0TT Test Drive

As you may have heard by now, GM is in the process of closing seven plants and slashing its workforce by 15% as it prepares to discontinue several models. Unfortunately, one of those several models includes the Cadillac CT6 full-size luxury sedan. The Cadillac CT6 was just introduced to Caddy’s lineup in 2015 in an attempt to take on the likes of the BMW 7-Series and the Mercedes-Benz S-Class but due to recent cuts by GM – that attempt was very short-lived.

Of course, the Cadillac CT6 had a long way to go to be considered a serious contender in the large luxury sedan segment, but after recently spending a week with the CT6 3.0TT with the new Super Cruise tech, we’re sad to see it go.

Stick with us over the next minutes of days as we go over some interesting facts and details about the Cadillac CT6.

2018 Cadillac CT6 3.0TT Exterior

Cadillac has always stated that it isn’t attempting to go head-to-head with the likes of Audi, BMW, and Mercedes-Benz. Instead, the Cadillac feels it is more of a niche luxury brand and we certainly agree with that intention.

With that in mind, we think the real competition here is between the Cadillac CT6, Genesis G90, Lexus LS, and the Lincoln Continental. To us, the Cadillac CT6 looks the most aggressive and bold out of the aforementioned cars but the Lexus LS is definitely the sexiest. The CT6’s sharp angles and tough stance are clearly influenced by the CTS. The 2019 model year CT6 – which will be the last model year of the CT6 – stepped up the exterior design game even further.

Influenced by the Cadillac Escala Concept, the 2019 CT6 is unquestionably a very sharp looking luxury sedan and goes head-to-head with the best looking large luxury sedans in this segment… dare we say even the German competition. Unfortunately, due to the recent GM cuts, the 2019 model year CT6 won’t be able to prove itself.

2018 Cadillac CT6 3.0TT Performance

Power for the 2018 Cadillac CT6 3.0TT comes from a 3.0-liter twin-turbo V6 engine making a total of 404 horsepower and a maximum torque of 400 lb-ft of torque. Mated to an eight-speed automatic transmission, 0 to 60 mph comes in just five seconds flat with a top speed of 155 mph.

Here’s how it compares to its rivals:

  • Audi A8 V6: 335-hp / 0-60 in 5.6 / $83,800.
  • BMW 740i: 320-hp / 0-60 in 5.4 / $83,650.
  • Genesis G90 3.3T: 365-hp / 0-60 in 5.3 / $68,350.
  • Lexus LS500: 416-hp / 0-60 4.6 / $75,200.
  • Lincoln Continental 3.0T: 400-hp / 0-60 in 5.0 / $65,370.
  • Mercedes-Benz S450: 362-hp / 0-60 in 5.4 / $91,250.

As you can see above, the American large luxury sedans are easily focused on offering you the most bang for your buck when it comes to power and performance. Honestly, we’re pretty upset to see the CT6 go. When compared to all the large luxury sedans in this segment, the Cadillac CT6 delivers top-notch handling and acceleration. Even though the 8-speed automatic transmission holds it back just a bit, the CT6 with the 3.0L twin-turbo V6 offers outstanding driver pleasure. Keep in mind, the 2019 Cadillac CT6 3.0TT will come with a 10-speed automatic that should solve that minor issue.

Fuel economy wise, the 2019 Cadillac CT6 3.0TT averages a total of 18/26 mpg* (city/highway).

Last but not least, the 2019 Cadillac CT6 will also see the addition of the CT6-V which will be powered by a 4.2L twin-turbo V8 making 550 horsepower and a maximum torque of 627 lb-ft. The CT6-V will also be mated to a 10-speed automatic transmission. 0-60 mph numbers are yet to be announced.

2018 Cadillac CT6 3.0TT Safety

Let’s talk about Super Cruise. Unlike Tesla’s AutoPilot, which mainly uses cameras to read road markings, the Cadillac Super Cruise system uses LiDAR map data along with sensors, GPS, and cameras to control the car. Unlike other semi-autonomous cars which require the driver to touch the steering to make sure they’re paying attention, the Super Cruise system is the world’s first ‘hands-free’ experience. Now, that doesn’t mean you can take your eyes off the road and scroll through Instagram. You still have to keep your eyes on the road. Super Cruise assures this by reading the driver’s face and eyes through the infrared cameras in the steering. If it senses you looking away for five seconds, the system will give you various warnings to look straight. If you’re in the mood to push your luck, the system will slow down the CT6 to a smooth and safe stop.

Super Cruise is pretty easy to learn — we picked it up in 30 seconds. After you turn on adaptive cruise control, just push the Super Cruise button. Once the steering wheel light bar turns green – the Caddy is in full control and you can kick back and relax – just make sure you’re looking straight.

Even though the CT6 will end production after the new 2019 model year, Cadillac has said that Super Cruise will be coming to all models after 2020.

2018 Cadillac CT6 3.0TT Overall

It is unfortunate that the Cadillac CT6 has fallen victim to GM’s recent plant closures and job cuts. We were actually looking forward (and still are) to the 2019 model year redesign and along with it the addition of the 550-horsepower CT6-V. But that’s the last we’ll see of it. Prices for the 2018 Cadillac CT6 3.0TT Sport start at just $67,590**. Visit your local AutoNation-affiliated Cadillac dealer for a test drive today.
