Which Buick Enclave version to buy: specs compared by generation

If the question is which Buick Enclave to buy, the catalogue numbers split the field into five bodies of work, not one “best SUV.” The current 3 generation (from 2024-06-01, SUV 5-doors) is the only pair with 333 hp, 442 Nm, a 2500 cm³ Gasoline engine, 4 cylinders Inline, Turbo, and an 8-speed Automatic — versions 2.5 AT (FWD) and 2.5 AT 4WD (AWD).

If the question is which Buick Enclave to buy, the catalogue numbers split the field into five bodies of work, not one “best SUV.” The current 3 generation (from 2024-06-01, SUV 5-doors) is the only pair with 333 hp, 442 Nm, a 2500 cm³ Gasoline engine, 4 cylinders Inline, Turbo, and an 8-speed Automatic — versions 2.5 AT (FWD) and 2.5 AT 4WD (AWD). That is the highest power and torque in the model line, and the smallest displacement. 0–100 km/h, top speed, fuel use, kerb weight, tank, and ground clearance for both 2.5 AT versions are not measured. If you need a timed sprint and a weighed kerb mass in the same row, the living catalogue still points at 2 generation, restyling 1 (from 2021-06-01): 3.6 V6 AT FWD does 0–100 in 7.2 s at 2233 kg and 314 hp; 3.6 V6 AWD AT is 7.5 s at the same 2233 kg. That 0.3 s is the measured cost of AWD on the restyled second generation. The pre-restyle 2 generation (2018-01-01 to 2021-05-31) 3.7 AT FWD is 7.3 s at 310 hp; its AWD twin is 7.7 s. The heaviest Enclave in the file is 1 generation, restyling 3.6 AT AWD at 2930 kg. The only top speed on record is 180 km/h, on 1 generation 3.6 AT 275 hp (FWD and AWD). There are no prices in this dataset, so “extra money” below means extra hardware as specified: gears, drive, boost, injection, fuel grade — not a sticker.

Generations: what actually changed in the numbers

Five catalogue generations sit on the same SUV 5-doors body type.

1 generation (2007-01-01 to 2013-12-31) has four versions, all named 3.6 AT, all 3564 cm³, 6 cylinders V-shaped, Front, transverse, 6-speed Automatic. Two are naturally aspirated (nadduv_en: No) at 275 hp / 202 kW at 6600 rpm and 340 Nm at 3200 rpm, multi-point injection, compression 10.2, bore × stroke 94 × 85.6, fuel 92. Two use Compressor at 286 hp / 210 kW at 6000 rpm and 340 Nm (rpm not measured), fuel 95, Euro 4. Kerb mass is 2260 kg (NA) or 2261 kg (Compressor). Ground clearance is 182 mm. Tank 83 l. 0–100 is 8.3 s on the 275 hp cars and 9 s on the 286 hp cars: the Compressor adds 11 hp and is 0.7 s slower to 100 km/h. Gross weight is measured only on the NA cars: 2910 kg FWD, 2930 kg AWD (+20 kg).

1 generation, restyling (2013-01-01 to 2017-12-31) keeps the 3.6 AT name and 3564 cm³ V-shaped 6, but switches to Direct injection (direct), compression 11.3, still 94 × 85.6, fuel 95, 288 hp / 215 kW at 6300 rpm, 366 Nm at 3400 rpm, 6-speed Automatic. Versus the 275 hp original: +13 hp, +26 Nm, compression +1.1. Versus the Compressor 286 hp: +2 hp and +26 Nm without Compressor. The restyle is much heavier: FWD 2908 kg versus 2260 kg (+648 kg); AWD 2930 kg versus 2260 kg NA AWD (+670 kg). Clearance rises from 182 mm to 194 mm (+12 mm). FWD 0–100 improves from 8.3 s to 7.8 s (−0.5 s) despite the extra mass. AWD 0–100 stays 8.3 s on restyle versus 8.3 s on the 275 hp original AWD. Wheels appear here: 255/65 R18, 255/60 R19, 255/55 R20. Rear brakes become Disc ventilated (front already Ventilated disc).

2 generation (2018-01-01 to 2021-05-31) is two 3.7 AT versions, 3649 cm³, 310 hp / 231 kW, 361 Nm, 6 cylinders V-shaped, Front, longitudinal, Direct injection (direct), boost No, fuel 95, 9-speed Automatic. Displacement is +85 cm³ versus 3564. Power is +22 hp versus restyle 288 hp and +35 hp versus original 275 hp. Layout flips from Front, transverse to Front, longitudinal. Gears go from 6 to 9. FWD 0–100 is 7.3 s (0.5 s quicker than restyle FWD 7.8 s, 1.0 s quicker than original FWD 8.3 s). AWD is 7.7 s. Kerb weight, tank, clearance, wheels, fuel use, top speed: not measured.

2 generation, restyling 1 (from 2021-06-01) renames the engines 3.6 V6 AT and 3.6 V6 AWD AT. Displacement is listed as 3600 cm³ (not 3649, not 3564). Power 314 hp / 230 kW at 6800 rpm, torque still 361 Nm now at 2800 rpm. Cylinder layout in the data is Inline, 6 cylinders, Front, transverse again, Direct injection (direct), boost No, fuel 92, 9-speed Automatic. Versus pre-restyle 3.7 AT: +4 hp, −49 cm³, engine orientation back to transverse, fuel grade 92 instead of 95. FWD 0–100 7.2 s versus 7.3 s (−0.1 s). AWD 7.5 s versus 7.7 s (−0.2 s). Kerb 2233 kg for both drives — 675 kg lighter than restyle-1 3.6 AT FWD 2908 kg, and 27 kg lighter than original 3.6 AT 2260 kg. Tank returns at 83 l. This is the only generation with measured city/highway consumption.

3 generation (from 2024-06-01) drops to 2500 cm³, 4 cylinders Inline, Turbo, 333 hp / 244 kW, 442 Nm, 8-speed Automatic, fuel 92, Direct injection (direct), Front, transverse. Versus 3.6 V6 AT: +19 hp, +81 Nm, −1100 cm³, one fewer gearbox ratio (8 vs 9), four cylinders instead of six, Turbo instead of No. Specific output 333 / 2.5 = 133.2 hp per litre, versus 314 / 3.6 ≈ 87.2 hp/l on the restyled V6 and 310 / 3.649 ≈ 85.0 hp/l on 3.7 AT. 0–100, mpg, mass, tank, clearance: not measured.

Do not merge the four 1 generation 3.6 AT rows: 275 hp and 286 hp are different engines (No vs Compressor, 92 vs 95, 8.3 s vs 9 s). Do not merge the two 2 generation 3.7 AT rows: same 310 hp, different drive and 7.3 s vs 7.7 s. Peak torque on 1 generation, restyling 3.6 AT is 366 Nm5 Nm above the 361 Nm of both 3.7 AT and 3.6 V6 AT. The 3 generation 2.5 AT family then jumps +76 Nm over that restyle peak (442 − 366).

Specific output, litres as displacement/1000:

Turbo plus 4 cylinders is the only step that leaves the ~77–87 hp/l band.

Performance, gas mileage, 0–100

Measured 0–100 km/h, fastest to slowest:

1. 3.6 V6 AT FWD — 7.2 s 2. 3.7 AT FWD — 7.3 s 3. 3.6 V6 AWD AT7.5 s 4. 3.7 AT AWD — 7.7 s 5. restyle 3.6 AT FWD — 7.8 s 6. restyle 3.6 AT AWD, original 3.6 AT 275 hp FWD, original 3.6 AT 275 hp AWD — 8.3 s 7. original 3.6 AT 286 hp FWD and AWD — 9 s

2.5 AT and 2.5 AT 4WD: 0–100 not measured. Top speed not measured on every version except original 3.6 AT 275 hp FWD and AWD at 180 km/h.

AWD penalty where both drives exist:

Gas mileage is measured only on 2 generation, restyling 1. 3.6 V6 AT FWD: city 13.1, highway 9 (units as in the file: L/100 km style figures). 3.6 V6 AWD AT: city 13.3, highway 9.4. AWD adds 0.2 in the city and 0.4 on the highway. Combined consumption not measured. All other generations: city, highway, combined, CO2 not measured. Eco class is Euro 4 only on the two 286 hp 3.6 AT Compressor cars; elsewhere not measured.

Dimensions, weight, tank, wheels

Kerb mass, where measured:

3.7 AT, 2.5 AT, 2.5 AT 4WD: kerb not measured. Gross: original 3.6 AT 275 hp FWD 2910 kg, AWD 2930 kg; all later versions not measured. Payload arithmetic on those two: 2910 − 2260 = 650 kg FWD, 2930 − 2260 = 670 kg AWD.

kg per hp (kerb / hp), only where both exist:

The restyled first generation is the worst mass-to-power ratio in the file and still beats the original NA car’s 0–100 on FWD (7.8 s vs 8.3 s).

Ground clearance: 182 mm on all four 1 generation 3.6 AT; 194 mm on both restyle 3.6 AT; not measured from 2 generation onward. Tank 83 l on 1 generation, 1 generation, restyling, and 2 generation, restyling 1; not measured on 3.7 AT and both 2.5 AT. Wheels only on restyle 3.6 AT: 255/65 R18, 255/60 R19, 255/55 R20. Suspension is Independent, spring front and rear on every version. Front brakes: Disc on original 3.6 AT, Ventilated disc from the restyle onward. Rear: Disc on original NA 3.6 AT, Disc ventilated on original Compressor 3.6 AT and on restyle 3.6 AT, Disc again on 3.7 AT, 3.6 V6 AT, and 2.5 AT.

Which version to choose

Buy 3 generation 2.5 AT or 2.5 AT 4WD** if the decision is “newest powertrain, highest hp and Nm, smallest engine.” 333 hp and 442 Nm from 2500 cm³ with Turbo is unique in this catalogue. Choose 2.5 AT for FWD or 2.5 AT 4WD for AWD; the data does not split their 0–100, mass, or mpg, so the drive label is the only measured difference. Accept that sprint, top speed, consumption, weight, tank, and clearance are not measured**.

Buy 2 generation, restyling 1 3.6 V6 AT** if the decision is the fastest timed Enclave and the lightest weighed one: 7.2 s, 2233 kg, 314 hp, 9-speed Automatic, FWD, fuel 92, city 13.1 / highway 9, tank 83 l. 3.6 V6 AWD AT is the same engine and mass with +0.3 s, +0.2 city, +0.4 highway. Specific output ≈ 87.2 hp/l; kg/hp ≈ 7.11**. That is the best measured kg/hp in the file.

Buy 2 generation 3.7 AT FWD if you want 310 hp, 3649 cm³, Front, longitudinal, 9 gears, fuel 95, and 7.3 s0.1 s behind 3.6 V6 AT, 22 hp above restyle 3.6 AT. Take 3.7 AT AWD only for AWD; it is 0.4 s slower. Weight and mpg not measured, so you cannot score kg/hp or fuel against the restyle-1 V6.

Buy 1 generation, restyling 3.6 AT FWD if you need the only generation with listed wheel sizes, 194 mm clearance (+12 mm vs original), Direct injection, 366 Nm (the six-cylinder torque peak), and a still-competitive 7.8 s. Know the cost in mass: 2908 kg, about 10.10 kg/hp, 675 kg heavier than 3.6 V6 AT. 3.6 AT AWD adds 22 kg and 0.5 s.

Buy 1 generation 3.6 AT 275 hp FWD or AWD if you want the lightest first-generation car (2260 kg), fuel 92, the only 180 km/h figure, compression 10.2, and 0–100 8.3 s without Compressor. AWD does not change the sprint on this pair. Gross weight is the only GVW in the catalogue.

Do not buy 1 generation 3.6 AT 286 hp for speed. Compressor and +11 hp versus the 275 hp 3.6 AT coincide with 9 s to 100, 0.7 s slower, same 340 Nm, kerb +1 kg. Euro 4 is listed only here. Fuel is 95 instead of 92. FWD and AWD share the same 9 s.

Reliability, engine problems, oil, filter jobs, and replacement cost are not measured in this file; search interest in those topics does not create failure rates. “For sale” and Avenir trims are not in the specification tables. What the extra hardware buys, in arithmetic only: AWD costs 0.3–0.5 s where it is timed after 2013 and 0 s on original 3.6 AT; Compressor costs 0.7 s versus NA 275 hp; restyling the first generation costs 648–670 kg and buys 13 hp, 26 Nm, 12 mm of clearance, and 0.5 s on FWD; stepping to 3.7 AT buys 22 hp and a 9-speed Automatic versus restyle 3.6 AT; restyling that second generation buys 4 hp, 92 fuel, 2233 kg, and the only mpg rows; 3 generation buys 19 hp and 81 Nm over 3.6 V6 AT by cutting 1100 cm³, two cylinders, and one gear, with Turbo, and leaves the stopwatch not measured.
