GM Turbocharged 2.0L LSY Engine Could Get An Output Boost

The GM turbocharged 2.0L inline four-cylinder LSY gasoline engine is currently in use in a variety of different GM vehicles and brands, and now, GM Authority has learned that a higher-output variant of the LSY engine could be in the works.
According to sources familiar with the matter, GM may develop a new variant of the turbocharged 2.0L I4 LSY gasoline engine producing not only more horsepower, but more torque as well, with twist topping out at around 290 pound-feet, as compared to the 258 pound-feet produced by the current engine variant. To note, the LSY currently produces 228 horsepower, 235 horsepower, or 237 horsepower, depending on the application.
In addition to producing more power and torque, this higher-output variant of the LSY engine may also produce slightly higher emissions.
For those readers who may be unaware, the GM turbocharged 2.0L inline four-cylinder LSY gasoline engine gradually replaced the turbocharged 2.0L I4 LTG engine previously used in various GM products. Compared to the LTG, the LSY is less powerful, but is more refined and runs cleaner (lower emissions). For example, under the hood of the Cadillac ATS, the LTG is rated at 272 horsepower and upwards of 295 pound-feet of torque, as compared to the LSY’s 237 horsepower and 258 pound-feet of torque.
Just a few applications for the turbocharged 2.0L inline four-cylinder LSY gasoline engine include the Cadillac XT4, GMC Acadia, Cadillac XT5, Cadillac XT6, Cadillac CT5, Cadillac CT4, and Chevy Blazer.
Although four-cylinder engines were at one time considered “underpowered” for certain applications, modern internal combustion technology has made the configuration appropriate for a wide range of segments. One good example of this is the GM 2.7L I4 L3B gasoline engine, which recently got a substantial torque boost to a peak of 430 pound-feet. Under the hood of light-duty pickups like the 2022 Chevy Silverado 1500 and 2022 GMC Sierra 1500, the L3B is more than up to the task when it comes to all the usual pickup truck activities.

Great, that engine needs more power or a higher output version.
poor hamsters… *sigh*
GOOD! its a week dull engine. The LTG was so much better. The IMPROVED 2.0 is several steps backwards. Please, dont want to here AGAIN the torque peaks at lower RPM bla bla bla. LESS is LESS….
I had a 2017 Camaro with the LTG and 6 speed manual transmission and it felt as strong as an old school 327. I traded it in for a ZL1 for which I regret. I wish I had kept that car, it averaged 30 mpg if I kept my foot out of it.
The camaro LS needs the 2.7. It might even get better economy with the 2.7 as these “tri-power” engines have a low valve lift economy mode. In the Silverado, the 2.7 never has the chance to enter this mode. It’s always on boost. Same with the 2.0.
GM are being smart about this new Tripower I4. The LTG had LSPI issues that left many buyers bitter about their high end Cadillac purchases which at low mileage needed new replacement engines.
Now GM introduces the LTG successor in a low output version first, lowering the risk of LSPI while engineers work out production bugs and perfect a higher output 2.0T variant.
Honda can build a 2.0T with well over 300 hp that runs for hundreds of thousands of miles. Doubtful GM will ever engineer such a great small engine but at least they should be able to match the LTG’s output.
Bet that as they add EVs they can play the numbers game with the CAFE Rules allowing capable combustion engines to attain the HP they were designed for (resulting in higher emissions). Side thought… will the recent EPA hand slap allow CAFE to loosen?
Assuming it will still require premium gas. I don’t mind that in a Perfromance car, but a little hard to take in a daily driver.
The problem I saw was the lower power did not require lower octane. If they had dropped the power but they ran off 87 it would have been a. Acceptable trade off.
Turbo cars generally get better fuel economy with higher octane, so that lessens a bit of pain. *shrug*
In Canada, That high octane gas costs on average an extra 35 to 45 cents a liter… so roughly in the States that would cost an average of $1.40 to $1.80 a US gallon extra over regular fuel. Please tell me where the savings are??? I deliberately stayed away from 4-cylinder turbo motors when shopping for my new 2022 GMC Acadia AWD V6. I am very pleased with the gas mileage I am getting even when I put it in AWD “Sport” mode and take it for a serious “romp” It’s a fun ride for what it is.
I have a 2020 CT5 with the V6 engine with 330 HP. Almost 80% of the 2020 CT5 cars came with the 4 cylinder engine.
I knew it was a dog and would only buy the V6 model. I love my car, but it wourld be such a disappointment with the 4 cylinder engine providing 238 HP.
What was GM thinking when they put such a DUD engine in a CADILLAC??????????????????
It’s how GM Kills brands, well, one of GM’s primary ways. After Killing Pontiac, Oldsmobile, Saturn, SAAB and trying desperately to Kill Opel and Lotus, GM turned It’s sights on Buick and Cadillac. They will be gone shortly. Its what GM does…
GM was thinking rhat the BMW m2 starts with a 2.0l that only makes 228HP yet sells a ton, we’re more stylish and powerful for a few bucks less. Why would we push more models with the V6????
I know we’re always comparing Cadillac to American cars, but the CT4/5 are going to be cross shipped with German cars, which unless you want to pay six figures are going to me less powerful than a standard American crossover.
Bmw does not follow sae testing and a 230hp bmw will nearly always walk away from a 250hp Cadillac. Is bmw underrating? Don’t know. But the fact is their 230hp is stronger than Cadillacs.
I’ve heard that BMW rates their horsepower based on wheel horsepower, while American cars generally use crank horsepower. Just as an example, the 6th gen Camaro with the 2.0l turbo LTG is rated at 275hp at the crank. At the dyno, that same 275hp is actually 230hp at the wheels, with transmission and other power losses. So if the BMW 228i is rated at 230hp wheel, it’s pretty much equivalent to 275hp crank.
So true. You would think there is someone at Cadillac or GM ho would say NO to a low powered Cadillac SUV but as usual the bean counters have the loudest voice at HQ.
I have a 2022 CT4 with the LSY. That engine provides more than adequate power in that car, with AWD.
Have you ever tried to do a 0-100kph or 0-60mph timer on the CT4? The old Cadillac ATS with the 2.0T LTG was doing about 5.5s. But the LTG had 40 more HP than the LSY.
I think my lawnmower has that motor… Maybe if I put a bigger turbo on it, it will go faster too…
Yes, for an base engine 700cid v20…..
Really? I look for gas mileage first & eliminate all premium gas recommended vehicles to begin my search for the best available vehicle. Then a test drive to see whether the power is adequate.
Me, I just look for a vehicle that all of my 6-foot 4-inch awesomeness can fit into comfortably. That usually means a truck or an SUV of some sort. Cars with sunroofs work too if I don’t mind snacking on insects during the trip.
nice, but won’t happen.
Stick it in a GMC Terrain and you’ll have a ton of happy customers.
I had the old LTG in an ’18 Equinox. The engine was real good for a small 4 cylinder, but the 93 premium it required was a PITA! The 3.6 V6 is a much better engine, fuel economy is similiar in similar vehicles, and requires 87.
Considering all the reasons we can’t get new cars and trucks and the fact we’re going all EV in the near future, isn’t this like betting on a dead horse.
It would be nice if they would focus on less out sourcing parts and make more of what they need them self. They have no control of how many cars they can build. It’s all controlled by out side companies.
They have extremely talented people who are as smart as anyone that the other companies have. Put them to work at GM owned companies that support GM with what they need.
Why are they so locked into two liters?
Higher emissions. Wonderful. That’s not going to help quiet down the EV supporters. Come on GM, throw us a bone. More ICE power but the same or lower emissions. I don’t want an EV and don’t want there to be any additional “evidence” for why should ultimately be the only cars sold.
Dan, I have the 18 equinox with the 2.0L and only put the 89 octane in it and I average 31 mpg in the summer. No knock just a lot of fun. I’ve been told u can use 87 with no issues, maybe a little less mpgs
