Cadillac CT5-V: which version to buy and why (specs compared)
If you are choosing a Cadillac CT5-V, the data split is simple: a 2990 cm³ 3.0 AT (355 hp in 2019 cars, 365 hp from April 2024) versus a 6162 cm³ 6.2 V8 (668 hp in both periods). Rear-wheel drive is the default; all-wheel drive exists only on the 3.0-litre cars. The 6.2 V8 is the only version with a measured top speed (322 km/h, 2019) and the only one with measured fuel use.

Prices are not in this catalogue. Search queries that add “Blackwing” still map onto these same named versions — the catalogue does not use that word.
Generations: what actually changed in 2024
The Cadillac CT5-V is one sedan generation, on sale from 2019-01-01 with no end date in the data. Three versions sat in the first period; three sit in the April 2024 restyling. Restyling is not a second generation.
1 generation (from 2019-01-01). Body: Sedan. Versions: 3.0 AT RWD 355 hp / 265 kW, 3.0 AT AWD 355 hp / 265 kW, 6.2 V8 RWD 668 hp / 491 kW. Fuel label: 95. Both 3.0 cars kerb at 1803 kg. The 6.2 V8 kerbs at 1879 kg, runs 245/40 R19 and 305/30 R19, and is the only CT5-V with measured economy: 18.1 / 11.2 / 14.7 L/100 km (city / highway / mixed) and top speed 322 km/h. 0–100 km/h is not measured on any 2019 version.
1 generation, restyling 1 (from 2024-04-01). Same Sedan. Versions: 3.0 AT RWD 365 hp / 268 kW, 3.0 AT 4WD AWD 365 hp / 268 kW, 6.2 V8 RWD 668 hp / 491 kW. Fuel label: 92. The 3.0 RWD still kerbs 1803 kg; AWD is now a named 3.0 AT 4WD at 1850 kg (+47 kg versus the restyled RWD 3.0 AT). The restyled 6.2 V8 kerbs 1939 kg — 60 kg heavier than the 2019 6.2 V8 (1879 kg) and 136 kg heavier than the restyled RWD 3.0 AT. Bore × stroke on the restyled 6.2 V8 is not measured. Top speed, 0–100, consumption, wheels, and ground clearance on the restyle cars: not measured.
What the restyle buys in numbers: +10 hp and +3 kW on every 3.0 (355→365 hp, 265→268 kW), torque unchanged at 542 Nm, fuel grade 95→92, and a 47 kg AWD penalty that did not show up as a weight delta in 2019 (both 2019 3.0 AT cars were listed at 1803 kg). The 6.2 V8 keeps 668 hp and 893 Nm; you lose the 2019 measured 322 km/h and the 18.1 / 11.2 / 14.7 figures, and you pick up 60 kg.
Cadillac CT5-V engine options and specs

| 3.0 AT | 2019 | 355 (265 @ 5600) | 542 @ 2400–4400 | 2990 | 6, V-shaped | AWD | 95 | 1803 |
| 6.2 V8 | 2019 | 668 (491 @ 6500) | 893 @ 3600 | 6162 | 8, V-shaped | RWD | 95 | 1879 |
| 3.0 AT | 2024 restyle | 365 (268 @ 5600) | 542 @ 2400–4400 | 2990 | 6, V-shaped | RWD | 92 | 1803 |
| 3.0 AT 4WD | 2024 restyle | 365 (268 @ 5600) | 542 @ 2400–4400 | 2990 | 6, V-shaped | AWD | 92 | 1850 |
| 6.2 V8 | 2024 restyle | 668 (491 @ 6500) | 893 @ 3600 | 6162 | 8, V-shaped | RWD | 92 | 1939 |
Compression: 9.8 on every 3.0 AT / 3.0 AT 4WD; 10 on every 6.2 V8. Bore × stroke: 86 × 85.8 on every 3.0; 103.25 × 92 on the 2019 6.2 V8; not measured on the restyled 6.2 V8. Valves per cylinder: 4 on all six versions.
Engine size and specific output (from the table only). 3.0 cars: 355 hp ÷ 2.990 L = 118.7 hp/L (2019); 365 hp ÷ 2.990 L = 122.1 hp/L (2024). Torque density: 542 Nm ÷ 2.990 L = 181.3 Nm/L. 6.2 V8: 668 hp ÷ 6.162 L = 108.4 hp/L; 893 Nm ÷ 6.162 L = 144.9 Nm/L. The 3.0 makes more horsepower and torque per litre; the 6.2 V8 makes 313 more horsepower than a 2019 3.0 AT (668 − 355) and 303 more than a restyled 3.0 AT (668 − 365), plus 351 Nm (893 − 542). Peak power arrives 900 rpm later on the V8 (6500 vs 5600). Peak torque on the 3.0 is a band (2400–4400); on the 6.2 V8 it is a point (3600).
Queries for “CT5-V engine name” and “engine sound” have no labels in this dataset beyond 3.0 AT, 3.0 AT 4WD, and 6.2 V8. Air filters, engine-bay photos, and crate engines for sale are not measured here.
Horsepower, torque, and kg per hp
2019 3.0 AT (either drive): 1803 kg ÷ 355 hp = 5.08 kg/hp. 2019 6.2 V8: 1879 kg ÷ 668 hp = 2.81 kg/hp. The V8 adds 76 kg (1879 − 1803) for 313 extra hp — 0.24 kg per extra horsepower if you treat the 3.0 RWD as the baseline. 2024 3.0 AT RWD: 1803 kg ÷ 365 hp = 4.94 kg/hp (0.14 kg/hp better than 2019 because power rose 10 hp at the same mass). 2024 3.0 AT 4WD: 1850 kg ÷ 365 hp = 5.07 kg/hp — almost the 2019 3.0 figure; AWD eats the restyle’s 10 hp advantage in mass terms. 2024 6.2 V8: 1939 kg ÷ 668 hp = 2.90 kg/hp, 0.09 kg/hp worse than the 2019 6.2 V8 solely because of +60 kg at unchanged 668 hp.
Horsepower by year in this file: 2019 3.0 AT 355 hp; 2024 restyle 3.0 AT / 3.0 AT 4WD 365 hp; 6.2 V8 668 hp in both 2019 and 2024. There are no separate 2020 / 2021 / 2022 / 2023 / 2025 / 2026 power figures — those search years either fall inside the 2019–restyle window or are not measured.
Performance, mpg / L/100 km, and what is not measured
0–100 km/h: not measured on all six versions. Top speed: 322 km/h on the 2019 6.2 V8; not measured on both 2019 3.0 AT cars and on all three restyle versions. Fuel use: only the 2019 6.2 V8 — 18.1 city, 11.2 highway, 14.7 mixed L/100 km. All other versions: not measured. CO2 and eco class: not measured on every version. Tank: 66 L on every version. If mixed 14.7 L/100 km is applied only to the car that has it, 66 L ÷ 14.7 L/100 km = 449 km of mixed range on the 2019 6.2 V8. Range for 3.0 AT, 3.0 AT 4WD, and the restyled 6.2 V8 is not measured.
“What the extra engine buys” in performance terms, strictly from measured cells: the 2019 6.2 V8 is the only CT5-V with a number for top speed (322 km/h) and the only one with a number for consumption. Choosing a restyled 6.2 V8 keeps 668 hp and 893 Nm but those two measured performance cells become not measured.
Dimensions, weight, tank, wheels
Length, overall size, and ground clearance: not measured on every version. Wheel sizes: 245/40 R19 and 305/30 R19 on the 2019 6.2 V8; not measured on both 2019 3.0 AT cars and on all 2024 versions. Gross weight: not measured on every version.
Kerb weight, which is measured:
- Lightest: 3.0 AT RWD — 1803 kg in 2019 and in 2024.
- 2019 3.0 AT AWD: also 1803 kg (no listed AWD penalty).
- 2024 3.0 AT 4WD: 1850 kg (+47 kg vs restyled RWD 3.0 AT).
- 2019 6.2 V8: 1879 kg.
- Heaviest: 2024 6.2 V8 — 1939 kg.
Suspension on all versions: Independent, spring front and rear. Brakes: Ventilated disc front; Disc ventilated rear (label as in the data).
Which Cadillac CT5-V version to choose
Choose the 2019 3.0 AT RWD (355 hp) if you want the lightest kerb in the file (1803 kg), 95 fuel, and RWD, and you accept 10 hp less than the restyle. Same 542 Nm, same 10-speed Automatic, same 66 L tank as every other CT5-V. 0–100, top speed, consumption, wheels, clearance: not measured.
Choose the 2019 3.0 AT AWD (355 hp) if you need AWD on a pre-restyle car. In this catalogue it does not cost mass versus the RWD twin (both 1803 kg). Same 355 hp, same 542 Nm, same 95 fuel. Distinguish it from the other 3.0 AT by drive: RWD vs AWD, not by power.
Choose the 2024 3.0 AT RWD (365 hp) if you want the best kg/hp among the six-cylinder cars (4.94 kg/hp) at the same 1803 kg as 2019, plus 92 fuel and +10 hp / +3 kW. Torque does not rise. This is the arithmetic “restyle win” on the 3.0: more power, no extra kilos.
Choose the 2024 3.0 AT 4WD (365 hp) if you need AWD after April 2024. You pay 47 kg (1850 vs 1803) and land at 5.07 kg/hp — essentially the 2019 3.0 ratio. Same 365 hp and 542 Nm as the restyled RWD 3.0 AT. It is the only version whose name is 3.0 AT 4WD.
Choose the 2019 6.2 V8 (668 hp) if the decision is power and you want the only measured top speed (322 km/h) and the only measured fuel figures (18.1 / 11.2 / 14.7). Versus a 2019 3.0 AT: +313 hp, +351 Nm, +3172 cm³, +76 kg, still RWD, still Automatic 10, still 66 L, still 95 fuel, plus the only listed wheels (245/40 R19, 305/30 R19). Best kg/hp in the whole file: 2.81. Displacement is more than double the 3.0 (6162 vs 2990); specific output is lower (108.4 vs 118.7 hp/L).
Choose the 2024 6.2 V8 (668 hp) only if you need the restyle and 668 hp. Power and torque match 2019; mass does not (1939 vs 1879 kg, +60 kg, 2.90 kg/hp). Fuel becomes 92. Top speed, consumption, wheels, and bore × stroke: not measured. Versus the restyled RWD 3.0 AT you still gain 303 hp and 351 Nm and add 136 kg.
Do not choose on 0–100, mpg of the 3.0, 2026 horsepower, length, or price — those cells are not measured (or, for price and for-sale listings, not in this dataset at all).
Short rule. Same 1803 kg and you can live with RWD: restyled 3.0 AT (365 hp) beats 2019 3.0 AT (355 hp) by 10 hp with no weight cost. Need AWD after 2024: 3.0 AT 4WD, knowing 47 kg. Need 668 hp and measured speed/economy: 2019 6.2 V8. Need 668 hp on a restyle car: 2024 6.2 V8, knowing 60 kg more and no measured 322 km/h or 14.7 L/100 km.
