Cadillac CT4-V specs: two 2.7 AT versions, one generation

Both engines: Gasoline, Front, transverse, Direct injection (direct), compression ratio 10, bore × stroke 92.25 × 102, 4 valves per cylinder, torque 515 Nm at 1800 rpm. Same 2.7 AT name; same 325 hp. Distinguishing field is drive: RWD vs AWD.

1 generation (start 2019-01-01, stop not measured) is a Sedan with 2 modifications. There is no second generation in the data, so there is no “which generation” trade of engines — only which 2.7 AT.

Both engines: Gasoline, Front, transverse, Direct injection (direct), compression ratio 10, bore × stroke 92.25 × 102, 4 valves per cylinder, torque 515 Nm at 1800 rpm. Same 2.7 AT name; same 325 hp. Distinguishing field is drive: RWD vs AWD.

CT4-V engine: same 2727 cc, same 325 hp — what actually differs

Power per litre is the same on both 2.7 AT cars: 325 hp ÷ 2.727 L ≈ 119.2 hp per litre. Specific torque is 515 Nm ÷ 2.727 L ≈ 188.9 Nm per litre. Those ratios do not change with AWD.

What changes is mass per horsepower:

The AWD car carries 0.18 kg extra per horsepower. Relative to the RWD kerb weight, 60 kg is about 3.7% more mass for the same 325 hp and the same 515 Nm.

Specific output does not buy you a different motor on AWD. You get the same Turbo Inline 4, the same 10-speed Automatic, the same 95 fuel. The extra hardware is drivetrain, not displacement.

CT4-V 0–100, top speed, and mpg (fuel use)

Version0–100 km/hTop speedCity L/100 kmHighway L/100 kmMixed L/100 km
2.7 AT (RWD)5.127315.87.811.9
2.7 AT (AWD)5.127016.48.112.3

Acceleration to 100 km/h is not a reason to pick AWD or RWD: both 2.7 AT versions are 5.1 s. The catalogue does not give a 0–60 mph figure; that search term is not a measured value here.

Top speed: RWD 2.7 AT 273 km/h, AWD 2.7 AT 270 km/h. Difference 3 km/h (about 1.1% lower on AWD).

Fuel:

On a 66 L tank, mixed range is a calculated figure from these numbers:

That is about 18 km less mixed range on AWD for the same tank. Highway range: 66 ÷ 7.8 × 100 ≈ 846 km (RWD) vs 66 ÷ 8.1 × 100 ≈ 815 km (AWD), about 31 km less.

CO2 is not measured on either version. Eco class is not measured on either version. Do not treat missing CO2 as “this car has no emissions figure in real life”; it is missing in this dataset.

CT4-V dimensions, weight, and tank

Gross vehicle weight is not measured on either 2.7 AT. Ground clearance is not measured on either. Length, wheelbase, and overall size in millimetres are not measured in this data — those search terms cannot be answered from the source.

What is measured:

VersionKerb weightGross weightClearanceTankWheels
2.7 AT (RWD)1640 kgnot measurednot measured66 L225/45 R17, 235/40 R18
2.7 AT (AWD)1700 kgnot measurednot measured66 L225/45 R17, 235/40 R18

Wheels and tank are identical. The only weight figure you can use to choose is kerb: +60 kg for AWD. Suspension is Independent, spring front and rear on both. Brakes are Ventilated disc front; rear is listed as Disc ventilated on both (English label from the data). Chassis spec does not split the two versions except mass and drive.

Which CT4-V version to choose

Choose the RWD 2.7 AT if you want the lower kerb weight (1640 kg), the higher listed top speed (273 km/h), and the lower fuel use (15.8 / 7.8 / 11.9). You keep 325 hp, 515 Nm, 5.1 s to 100 km/h, 10-speed Automatic, and the same 2727 cc Turbo Gasoline engine. Power-to-mass is the better of the two: 5.05 kg/hp vs 5.23.

Choose the AWD 2.7 AT if you need AWD and will accept 1700 kg, 270 km/h, and 16.4 / 8.1 / 12.3 L/100 km. You do not get more horsepower. You do not get a shorter 0–100. You do not get a larger tank. You get drive on all wheels and 60 kg.

There is no third engine option in the data. Searches for “engine options” on this model resolve to one 2.7 AT powertrain in two drives. There is no Blackwing line, no second generation, and no price in this source — price and “for sale” are not measured.

What the extra mass “buys” in numbers: +60 kg, +0.6 / +0.3 / +0.4 L/100 km, −3 km/h top speed, same 5.1 s, same 325 hp. If those four deltas are acceptable for AWD, take AWD 2.7 AT. If they are not, the RWD 2.7 AT is the version the arithmetic prefers.

Generations: only 1 generation from 2019, Sedan, two versions, no restyling row in the data. You are not choosing a later generation with more power; you are choosing drive on the same 325 hp 2.7 AT.

Reliability and typical problems are not measured in this dataset. A buying choice from these facts is mass, fuel, top speed, and RWD vs AWD — not a defect list.
