Cadillac CT4: Which Version Should You Buy?
The Cadillac CT4 range is easiest to choose by working backward from three decisions: how much power you need, whether you want RWD or AWD, and whether you prefer an Automatic or Manual gearbox. The first and only generation is a Sedan produced from 2019 onward, with seven listed versions.
The Cadillac CT4 range is easiest to choose by working backward from three decisions: how much power you need, whether you want RWD or AWD, and whether you prefer an Automatic or Manual gearbox. The first and only generation is a Sedan produced from 2019 onward, with seven listed versions. The 2.0 AT offers 237 hp and the lowest measured kerb weight; the 309 hp 2.7 AT provides substantially more torque while retaining a four-cylinder engine; the 327 hp 2.7 AT is the strongest four-cylinder choice; and the 472 hp 3.6 V6 MT and 3.6 V6 AT sit at the performance end of the catalogue. Prices and sale listings are not included in the supplied data, so the comparison below focuses on what each version provides technically.
Cadillac CT4 generations: what changed?
The Cadillac CT4 has one generation rather than several generations to compare. The 1 generation began in 2019 and remains in production, according to the catalogue data. It uses a Sedan body and contains seven versions. The initial range, dated from 2019, comprises 2.0 AT and 2.7 AT variants with either RWD or AWD, plus a more powerful RWD 2.7 AT. The 3.6 V6 MT and 3.6 V6 AT versions are dated from 2021. Therefore, the significant change within this generation is the addition of the 472 hp V-shaped six-cylinder engine and a choice between Manual and Automatic transmissions at that output.
Cadillac CT4 engine options and specs
Every listed Cadillac CT4 engine uses Gasoline, Turbo boost and direct injection. Each cylinder has four valves, and the compression ratio is 10 across the range. The two four-cylinder engine sizes are 1998 cc and 2727 cc; the six-cylinder engine has a displacement of 3564 cc.
| Version | Power | Torque | Displacement | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 2.0 AT, RWD | 237 hp (177 kW) at 5000 rpm | 350 Nm at 1500–4000 rpm | 1998 cc | Gasoline, 95 | 4, Inline | Turbo | 8-speed Automatic | RWD |
| 2.0 AT, AWD | 237 hp (177 kW) at 5000 rpm | 350 Nm at 1500–4000 rpm | 1998 cc | Gasoline, 95 | 4, Inline | Turbo | 8-speed Automatic | AWD |
| 2.7 AT, RWD | 309 hp (231 kW) at 5600 rpm | 472 Nm at 1800 rpm | 2727 cc | Gasoline, 95 | 4, Inline | Turbo | 10-speed Automatic | RWD |
| 2.7 AT, AWD | 309 hp (231 kW) at 5600 rpm | 472 Nm at 1800 rpm | 2727 cc | Gasoline, 95 | 4, Inline | Turbo | 10-speed Automatic | AWD |
| 2.7 AT, 327 hp, RWD | 327 hp (240 kW) at 5600 rpm | 515 Nm at 1800 rpm | 2727 cc | Gasoline, 95 | 4, Inline | Turbo | 10-speed Automatic | RWD |
| 3.6 V6 MT | 472 hp (347 kW) at 5750 rpm | 603 Nm at 3500 rpm | 3564 cc | Gasoline, 95 | 6, V-shaped | Turbo | 6-speed Manual | RWD |
| 3.6 V6 AT | 472 hp (347 kW) at 5750 rpm | 603 Nm at 3500 rpm | 3564 cc | Gasoline, 95 | 6, V-shaped | Turbo | 6-speed Automatic | RWD |
The RWD and AWD forms of the 237 hp 2.0 AT have identical listed engine output, torque and eight-speed Automatic specifications. The same pattern applies to the 309 hp 2.7 AT: choosing AWD does not alter its listed 309 hp, 472 Nm or ten-speed Automatic gearbox.
Cadillac CT4 horsepower and torque comparison
Moving from the 237 hp 2.0 AT to the 309 hp 2.7 AT adds 72 hp and 122 Nm. Displacement increases by 729 cc, while the gearbox changes from an eight-speed Automatic to a ten-speed Automatic. This makes the 309 hp 2.7 AT the most direct step up for a buyer who wants more output without moving to the six-cylinder versions.
The 327 hp 2.7 AT uses the same 2727 cc displacement as the 309 hp 2.7 AT but adds 18 hp and 43 Nm. Both reach peak power at 5600 rpm and list peak torque at 1800 rpm. Since the 327 hp version is RWD only in this data, the 309 hp 2.7 AT is the relevant option when AWD is required.
At the top of the range, the 3.6 V6 MT and 3.6 V6 AT each deliver 472 hp and 603 Nm. Compared with the 327 hp 2.7 AT, either 3.6 V6 version provides 145 hp and 88 Nm more. The choice between them is about the gearbox rather than engine output: one is a six-speed Manual, while the other is a six-speed Automatic.
Calculated from the supplied displacement and output figures, the 2.0 AT produces about 118.6 hp per litre. The 309 hp 2.7 AT produces about 113.3 hp per litre, the 327 hp 2.7 AT about 119.9 hp per litre, and each 472 hp 3.6 V6 version about 132.4 hp per litre. On this measure, the 3.6 V6 versions have the highest specific output, while the 327 hp 2.7 AT narrowly leads the 2.0 AT among the four-cylinder choices.
Cadillac CT4 performance, mpg, and economy
Acceleration from 0–100 km/h is not measured for any listed version. Top speed is not measured for any listed version. City fuel consumption, highway fuel consumption and combined fuel consumption are also not measured for all seven versions. CO₂ output and environmental class are not measured.
Because those measurements are absent, horsepower and torque should not be converted into unsupported acceleration or economy claims. The confirmed comparison is limited to the supplied outputs: 237–472 hp and 350–603 Nm. Every version has a 66-litre fuel tank and uses fuel labelled 95.
Cadillac CT4 dimensions, weight, and wheel sizes
Overall length, width, height and wheelbase are not measured in the supplied data, so a Cadillac CT4 dimensions or size comparison cannot be made from this catalogue entry. Ground clearance and gross weight are also not measured for any version.
Measured kerb weight is available for selected RWD versions:
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| 2.0 AT, RWD | 1570 kg | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 2.0 AT, AWD | not measured | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 2.7 AT, RWD, 309 hp | 1640 kg | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 2.7 AT, AWD, 309 hp | not measured | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 2.7 AT, RWD, 327 hp | 1640 kg | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 3.6 V6 MT | 1751 kg | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
| 3.6 V6 AT | 1800 kg | not measured | not measured | 66 L | 225/45 R17; 235/40 R18 |
The 309 hp and 327 hp RWD 2.7 AT versions both weigh 1640 kg, so the additional 18 hp and 43 Nm of the 327 hp version carry no measured kerb-weight increase. The 3.6 V6 MT is 49 kg lighter than the 3.6 V6 AT despite matching its 472 hp and 603 Nm.
Using the available RWD figures, the 2.0 AT carries about 6.62 kg per horsepower. The 309 hp 2.7 AT has about 5.31 kg per horsepower, while the 327 hp 2.7 AT improves that to about 5.02 kg per horsepower. The 3.6 V6 MT has about 3.71 kg per horsepower, and the 3.6 V6 AT has about 3.81 kg per horsepower. These calculations make the 3.6 V6 MT the strongest measured power-to-weight choice in the catalogue.
All versions list independent spring suspension at the front and rear. Ventilated disc brakes are specified at both ends, and the listed wheel sizes are 225/45 R17 and 235/40 R18 throughout the range.
Cadillac CT4 problems, engine noise, and reliability
Engine problems, engine-light causes, engine noise, repair procedures, air-filter information and reliability measurements are not provided. No version can therefore be ranked for reliability from the supplied facts. A buyer investigating a particular used car would need separate condition and service evidence; the catalogue data only supports a specification comparison.
Which Cadillac CT4 version should you buy?
Choose the 2.0 AT if 237 hp, 350 Nm and an eight-speed Automatic meet your requirements. Its RWD form has the lowest measured kerb weight at 1570 kg. Select between RWD and AWD according to drive preference; the AWD version’s kerb weight is not measured.
Choose the 309 hp 2.7 AT when you want 72 hp and 122 Nm more than the 2.0 AT, together with a ten-speed Automatic. It is also the most powerful specification in this data that offers both RWD and AWD.
Choose the 327 hp 2.7 AT when you want the strongest four-cylinder version. It adds 18 hp and 43 Nm over the 309 hp 2.7 AT without changing the measured 1640 kg kerb weight, but it is listed only with RWD.
Choose the 3.6 V6 MT when maximum output, a Manual gearbox and the best calculated power-to-weight ratio are the priorities. It provides 472 hp and 603 Nm at 1751 kg. Choose the 3.6 V6 AT when you want the same power and torque with an Automatic, accepting a measured 49 kg weight increase to 1800 kg.
The data contains no Cadillac CT4 price or Cadillac CT4 for-sale figures, so it cannot show what the extra output costs. On specifications alone, the 309 hp 2.7 AT is the flexible middle choice because it combines a sizable output increase with either RWD or AWD; the 327 hp 2.7 AT is the sharper four-cylinder choice; and the 3.6 V6 MT is the clearest performance choice by measured power-to-weight ratio.
