When we shared with you the 2019 Cadillac CT6 powertrain lineup earlier this year, we did not have the power ratings for the new 2.0L turbo-charged engine (production code LSY). But now, the numbers are in – and they’re not that impressive.
The Numbers
According to official ratings from Cadillac and the Society of Automotive Engineers (SAE), the 2019 CT6 with the new, boosted four-cylinder engine will be make 237 horsepower at 5,000 RPM and 258 pound-feet of torque at 1500-4000 RPM.
Availability
The new 2.0L turbocharged engine on the 2019 Cadillac CT6 is available on the Luxury and Premium Luxury trim levels, both of which are rear-wheel-drive.
Comparisons
Notably, that’s 28 horsepower and 37 pound-feet of torque less than the 2.0L turbo engine (production code LTG) used in the 2016, 2017 and 2018 CT6. However, the torque on the new engine is achieved at as low as 1500 RPM, which is half as much as on the outgoing motor.
In addition, the new 2.0 liter is now mated to Cadillac’s new 10-speed automatic transmission, whereas the outgoing unit was paired with an 8-speed gearbox.
The next available engine in the 2019 Cadillac CT6 lineup is the naturally-aspired 3.6L V6 (production code LGX). This motor makes 335 horsepower at 6800 RPM and 284 pound-feet of torque at 5300 rpm.

Would like to see how it compare in performance ,gas mileage and refinement before making judgement. What I am hoping for is a more refined Engine without sacrificing very much or no decrease in performance or gas mileage. If they went to this Engine to just save gas it dosen’t make sense, because most people don’t buy these type of cars for gas saving.

Well, Motor Trend review in CT4 stated engine was coarse and grainy!
Alex Luft
In CT4?

It was hard enough for me when Cadillac the V6 standard equipment, I’m an old school Cadillac V8 guy. Making a 4 cylinder standard in a Cadillac is sacrilege as far as I’m concerned.
Van Straker
Completely agree, this was a typical dumb GM move. Now the CT6 appears to be cancelled…. GM is run by incompetants.
Brian A Clark
I agree, I think it should be a no cost option but one of their 6’s should be std. If someone wants the 4 they can order it which I doubt many will. Alex, any idea what the take rate is on the engine line up? I’d say 6’s are the biggest movers?
Alex Luft
From what I know, the 2.0L Turbo I4 and 3.6L NA V6 production on the CT6 is split up around 35-65.

I predict that with the LSY 2.0T with full bls. of torque at 1500 RPM with the 10 Speed transmission, performance will be similar to the ’18 models w/ the LTG setup. That might be good or bad to some on here give or take.
I’m more interested on the base Blackwing that will be available on Platinum and hopefully on the Sport model as well.

Man will GM put to rest the 3.6 in the Cadillac lineup.
Felix
How many 2.0’s did the CT6 sale compared to the V6’s? If possible I would like to know the amount of sales of the 2.0 ,the 3.0 and the 3.6 from introduction until now?
Alex Luft
Unfortunately, this is unknown. We have tried obtaining the data every which way imaginable, but to no avail.

Honda Civic Type R: 2.0L turbocharged I4, 306 hp, 295 lb-ft. …
Almost twice the power fo around a third of the price. This is just one of the reason why Cadillacs sales are in the toilet.
Dwight Looi
Rubbish engine + Start/Stop = unbuyable car. Yeah, go pander to the tree huggers and global warming coolaid drinkers. Sorry, GM, they buy electric cars anyway and won;t give you a second look.

BTW, the LSY 2.0T is utter rubbish. 258 lb-ft @ 1500 rpm is NOT 2000 rpm sooner than the outgoing LTG engine. The LTG engine makes 260 lb-ft by 1700 rpm anyway so you are looking at less than 200 rpm in spool up improvement for all the torque and power you lose.
Alex Luft
1. You can disable start/stop.
2. Not sure if you will feel a difference in the lack of on-paper power/torque of the LSY when compared to the LTG. I certainly didn’t.
Drive one.

This is ridiculous. The CT6 should not even offer a “four”…. Where the hell is the V8 that SHOULD be in this car. No wonder nobody takes this car seriously, including Cadillac/GM……
John Engelman
Big cars need V8’s. I have a Chrysler 300C with a 5.7 V8. It doesn’t Turbo’s or a supercharger,that car moves,and it doesn’t sound like the engine is working overtime to get it down the road. My 2018 CT6 Platinum doesn’t sound like a V8, but rather an engine straining to get the car down the road. The turbo lag is awful, and you hafta keep kicking it down to get it to go……sad, especially for $93,000……….
Diana
Question, I was told by a friend to leave the engine running on the new ct6 turbo for a few seconds before I turn off the engine
it helps keep the engine from any build up, is the true?
Alex Luft
Diana – this was a best practice for older turbo-charged engines but I’m not sure it has any impact on the modern turbo motors.
