The 2021 Cadillac CT5 sedan with the available V6 engine has received slightly improved fuel economy ratings from the U.S. Environmental Protection Agency.
The 2021 model-year Cadillac CT5 with the turbocharged GM 3.0L LGY V6 engine and rear-wheel drive has an EPA-estimated fuel economy rating of 19 mpg city, 28 mpg highway and 22 mpg combined. An identically equipped 2020 model-year CT5, by comparison, was rated at 19 mpg city, 26 mpg highway and 21 mpg combined.
Versions with the 3.0L V6 engine and all-wheel drive also receive a slight improvement, rated at 18 mpg city, 26 mpg highway and 21 mpg combined. For 2020, the same model was rated at 25 mpg highway, though the city and combined ratings have remained the same year-to-year.
| Trim Level | Drive Type | 2021 MY MPG | 2020 MY MPG | + / – MPG |
|---|---|---|---|---|
| CT5 Premium Luxury RWD | City | 19 | 19 | - |
| Highway | 28 | 26 | +2 | |
| Combined | 22 | 21 | +1 | |
| CT5 Premium Luxury AWD | City | 18 | 18 | - |
| Highway | 25 | 26 | +1 | |
| Combined | 21 | 21 | - |
The performance-focused 2021 Cadillac CT5-V also gets a higher fuel economy rating than the 2020 model. Last year, the rear-wheel-drive Cadillac CT5-V was rated at 18 mpg city, 26 mpg highway and 21 mpg combined, but the 2021 model has a higher highway fuel economy of 27 mpg. All-wheel-drive models get a bigger increase, however, moving from 17 mpg city, 25 mpg highway and 20 mpg combined to 18 mpg city, 26 mpg highway and 21 mpg combined.
As a reminder, the GM 3.0L LGY V6 produces 335 horsepower and 400 pound-feet of torque in the Cadillac CT5 550T, along with 360 horsepower and 405 pound-feet of torque in the CT5-V. The engine is paired with a GM 10-speed automatic transmission in the sedan, along with standard rear-wheel drive or optional all-wheel drive.
| Trim Level | Drive Type | 2021 MY MPG | 2020 MY MPG | + / – MPG |
|---|---|---|---|---|
| CT5-V RWD | City | 18 | 18 | - |
| Highway | 27 | 26 | +1 | |
| Combined | 21 | 21 | - | |
| CT5-V AWD | City | 18 | 17 | +1 |

The 2021 Cadillac CT5 received a number of small changes from the 2020 model, including a new Diamond Sky Special Edition Package, a 12-inch reconfigurable color driver cluster and a revised selection of available exterior colors, among other revisions. Prices for the 2020MY sedan start at $37,890 USD for the entry-level Luxury model, which includes the standard turbocharged GM 2.0L LSY four-cylinder engine, the 10-speed automatic and rear-wheel drive.

Put the twin turbo 3.6 from the CTS V-Sport in it and now we’re talking!
C pillar looks terrible.
The rest is a great looking car..still kinda want it
It’s a little odd, but I think the C pillar in every other Cadillac sedan until now is even worse. The supersharp cutoff of the window is in stark contrast to almost every other car out there and I think conveys a lack of subtlety to the styling, rather like the vertical rear taillights (which I understand are meant to honor the glory days of Cadillac, but look antiquated with the highly crafted taillights that are present in most other cars these days, but kudos to Cadillac from starting a transformation away from them). I don’t think this C-pillar will survive past this iteration of the CT5, but I vastly prefer it to the “I’m not even trying” look. My hope is that they try something that borrows from BMW rather than the Accord.
Would be fine if it was actual Glass. GM just went the Cheap route on their Luxury Division vehicle.
Was this achieved through tuning?
The turbocharged 3.0L V6 sort of demonstrates that Chevrolet’s 6.2L V8 would be better as it is capable of better performance with it’s 490 hp output and with displacement on demand can still manage the same gas mileage as the turbo V6.
Not impressed. My 2006 Buick Lucerne with the Northstar V8 is rated about the exact same. Not much less power. Larger, more comfortable, just as nice looking and heavier. And it does it all with an old-fashioned 4 speed auto with overdrive. Tell me again why we need 6, 8, 9 or 10 speeds?
“My 2006 Buick Lucerne with the Northstar V8 is rated about the exact same.”
Allow me to fact check that.
2009 Buick Lucerne:
– Atmospheric 4.6L Northstar V8, 4-speed auto
– 292 horsepower, 288 pound-feet of torque
– 15 MPG city, 22 MPG highway, 18 MPG combined
2021 Cadillac CT5 550T Prem Lux:
– Twin-Turbo 3.0L V6, 10-speed-auto
– 335 horsepower, 400 pound-feet of torque
– 19 MPG city, 28 MPG highway, 22 MPG combined
The Cadillac CT5 makes 43 horsepower and 112 pound-feet of torque more, WHILE also being more efficient, to the tune of +4 MPG in the city, +6 MPG on the highway and +4 MPG combined.
Now, let’s revisit your original statement:
“My 2006 Buick Lucerne with the Northstar V8 is rated about the exact same.”
Rated “about the exact same?” Man, it is NOT EVEN CLOSE.
The CT5 also runs cleaner from an emissions standpoint, emitting about 38 percent less CO2. Had it been on sale today, the Lucerne would cost GM in EPA. It would also not be capable of being sold in China due to the stringent emissions laws enacted over the past 24 months, and getting more stringent still. All engines in the CT5 (except for the upcoming blown 6.2L V8 in the Blackwing) meet emissions reqs today and for the next decade (give or take, depending on how rapidly BIN gets advanced).
On top of the Cadillac being superior in power, fuel economy and emissions, there are also more qualitative elements that the specs/figures do not show. For instance, the CT5 is simply a much better driving car. It’s also a lot more agile and engaging, while being a lot safer. And it’s also loaded to the gills with technology (which adds weight). That’s what ten years of development progress has done. That’s the reason for a 10-speed gearbox and turbo-charged engines with advanced valving, aspiration and fuel delivery controls.
It’s not about defending Cadillac. It’s about facts, which have led us to the truth.
No. Your lucerne is a 15.0 car and we don’t don’t need to get into looks but they’re not comparable.
Fwd generally had less drivetrain loss and with the big tall gears they spun at a low rpm in the highway for decent mpg. With the 4 speed you have to pick the right speed to floor it or it’s going to be extremely uninspiring and lackluster. I wish people would stop claiming the 10 speed is for mpg. They stopped getting better mpg after the 6 speed. The extra gears are for optimal acceleration and power at any starting speed, driveability and mpg. It’s like your muscle car having 4.56 and 3.08 gears. It’s going to have the acceleration of the 4.56 and mpg of the 3.08.
They have also changed how they rate mpg and your car would be rated noticeably lower today.
@Mike: I’m not sure you got my point at all. Maybe you and the others are just too happy to defend Cadillac at all costs? Don’t take me wrong, I love Cadillac’s and I’m a GM guy overall. I ONLY used my ’06 Lucerne as a point of reference, and not a benchmark for crying out loud! So to be clear: My point is that the automotive industry has fallen flat on MPG increases. Yes the cars are safer today and that does add weight. But they have also found other weight savings in other areas. I’m not blaming anyone in particular, but only saying that I’m not impressed with this alleged increase when we have not gained any ground in 30 years now.
BTW, my Lucerne will take down 28 MPG all day long on the highway and there is certainly no lack of power or the right gear. For a 14 year old car with 163,000 miles, I’ll put it up against nearly anything on the market today in terms of power, refinement, quiet, features and MPG. Just saying.
I sure wish Cadillac would put the Escalade or Lyriq style interior in this vehicle before they cancel it.
I would love to own a Cadillac ICE with an interior that belongs in a Cadillac and not a Chevrolet !
Totally agree with you on the Interior Department. The Escalade interior should have been in every single new Cadillac the last three years.
28 city with a V? Impressive (or typo)
So now the 3.0 liter engine is actually rated more realistically. Funny how the EPA is robbing from some and giving back to others. Makes little sense.
Caddy makes only TWO midsized sedans and 4 grocery getters now ! No full sized luxury sedan, no coupe and no convertible ! better off with a Chevy, Buick or GMC !
