report engine options shrink to two for 2020 cadillac ct6

Cadillac’s CT6, which remains without a home after January 2020, will shed an engine offering for the upcoming model year.

The report comes by way of AutoVerdict, which got its hands on a 2020 CT6 order guide. Initially offered with a 2.0-liter four-cylinder for the base, rear-drive model, the CT6 range spanned a plug-in hybrid model (utilizing that same 2.0-liter), a 3.6-liter V6, twin-turbo 3.0-liter V6, and, as of 2019, a 4.2-liter Blackwing V8.

For 2020, only the naturally aspirated V6 and the Blackwing remain.

Last year, Cadillac dropped the hybrid option in America, leaving Chinese customers as the sole benefactors of the green option. In April, news came that the base 2.0L was gone, and with it the CT6’s only rear-drive build configuration.

Now, the order guides state that only the 3.6L and 4.2L will carry on for 2020. Cadillac’s Romulus, Michigan-built 3.0TT, which generated 404 horsepower and 400 lb-ft of torque in uplevel CT6s, disappears in favor of the more potent Blackwing, though power figures remain TBD. The detuned version of the engine found in the short-lived CT6-V will be standard fare in the range-topping CT6 Platinum.

As per Cadillac’s confusing, metric-centric power badging strategy, V8 models will carry a “800T” on the trunklid, while V6 versions see a “400.” These rounded-up figures signify the vehicle’s torque figure in Newton-meters. It’s possible there’s a better way to make other drivers envious, but Cadillac can do whatever Cadillac wants.

The 3.0TT may be gone from the CT6, but the engine soldiers on in the midsize CT5 — Cadillac’s replacement for the CTS. In that model, due out for 2020, it makes 335 hp and 400 lb-ft. It’s possible the engine will see further use in the brand’s lineup, though we’ll have to wait until the May 30th debut of the CT4 compact sedan, which, like the CT5, carries a V-badged performance variant.

    To me, this is a sweet looking car that does look like a Caddy. With the V-8, it would be a really nice ride. Agreed that dumping the turbo V6 was a terrible mistake. It may be the perfect engine for this car and probably had the potential to be even more powerful. Getting rid of the 2.0 makes sense because offering that engine on this car offended God, which is more risk than GM can afford right now.

    Given the historically adversarial relationship Cadillac engines have had with reliability, I would be VERY reluctant to purchase a Blackwing equipped car. ....I keep remembering the V8-6-4, the HT4100, the Northstar....and thinking the folks who got the 1976 Sevilles with the Olds or Chevy V8s lucked out.

  • Wjtinfwb How does the ICE mid-engine C8 platform work for... anything else? A sedan? SUV? With a mid engine configuration? A mid-engine SUV will have to be Suburban sized to offer the utility of a CRV. GM should dust off the Omega platform designed for the Cadillac CT6 for an SUV/Sedan offering with exceptional handling, Rear or AWD capability and acceptable space utilization. They also need to focus on interior fit & finish, trim choices and high quality final engineering and assembly. What GM doesn't need is another half-baked product with a storied and prestigious badge on the decklid and a premium price on the Monroney. No more Cimarron's, Allante's or X-cars needed to tarnish the reputation of Corvette.
  • InCogKneeToe BUILD It and they will come.By Build It, I mean a Vehicle that the Customer Wants and it works for them. It could be called Chevette for all that that matters. The Mach E's success isn't because it totes the Mustang on it.Just build what people want, the next Caravan/Taurus/Beetle/Maverick (truck).
  • YellowDuck Wait...how do you make a mid-engine crossover? Or even a 4-door coupe? Me not get.
  • 28-Cars-Later Thanks Corey. The head stud job on NOrthSTAR-T was $3K *years ago* as it involves an engine pull so rear wheel arch rust in and of itself isn't a show stopper. I'll be sure to check out the trunk as it may start to add up on deferred maintenance. Supposedly this was garaged so the underneath the rockers etc. should be decent but if those are shot its not gonna work.
  • Mark 2016 Hyundai Sonata Hybrid, G4NG engine with connecting rod bearing issues. Engine needs to be replaced, but Hyundai is denying warranty claim. I have all maintenance records from mile zero. It has been in Hyundai Service department 5 time in 4 months. They added the knock sensor and software update to let you know the engine is about to blow up. They kicked the can down the road doing patch work until the car was past the 120k extended extended warranty. I have that documentation too. So how can I join the class action law suit or find a Lawyer that handles these types of issues?
