Alpina XD4: which version to buy — 3.0 AT 388 hp vs 3.0 AT 394 hp
If you are choosing an Alpina XD4, the catalogue has two 3.0 AT diesel versions, not two different engines. Both are AWD, Automatic with 8 gears, SUV Coupe, 2993 cm³, Inline 6, Turbo.
If you are choosing an Alpina XD4, the catalogue has two 3.0 AT diesel versions, not two different engines. Both are AWD, Automatic with 8 gears, SUV Coupe, 2993 cm³, Inline 6, Turbo. The fork is generation timing and a handful of measured numbers: the 2 generation 3.0 AT (388 hp / 770 Nm, 2018-01-01–2021-05-31) versus the 2 generation restyling 3.0 AT (394 hp / 800 Nm, from 2021-06-01, stop not measured). Acceleration to 100 km/h is 4.6 s on both; top speed is 268 km/h on both. The restyling is +6 hp, +4 kW, +30 Nm, +100 kg kerb weight, +0.2 L/100 km mixed, +4 g/km CO2, and −90 kg payload. There is no third Alpina XD4 engine in this data set.
Search queries such as alpina xd4 for sale, alpina xd4 price, bmw alpina xd4 price, and alpina xd4 mobile de are common. This catalogue has no sale listings and no prices, so “which to buy” here means which 3.0 AT matches the numbers you actually need.
Generations: one Alpina XD4 line, two 3.0 AT specs
The Alpina XD4 in these data is one model with 2 generation coverage. Restyling is the same generation, not a new one.
2 generation (2018-01-01 to 2021-05-31). Body: SUV Coupe. Versions: 1 — 3.0 AT at 388 hp (285 kW) and 770 Nm. Production window is closed.
2 generation, restyling (2021-06-01, stop not measured). Body: SUV Coupe. Versions: 1 — 3.0 AT at 394 hp (289 kW) and 800 Nm. If you need a 2022 Alpina XD4 or later, this is the only row that can still be in production; the earlier 3.0 AT stopped on 2021-05-31.
Both generations share Diesel, 6 cylinders, Inline, 4 valves per cylinder, Turbo, Front, longitudinal, compression 16, bore × stroke 84 × 90, fuel Diesel, Automatic, 8 gears, AWD, 68 L tank, wheels 255/45 R20 and 285/40 R20, Independent, spring front and rear, Ventilated disc front, Disc ventilated rear. Ground clearance is not measured on either 3.0 AT. Fuel system is not measured on either. Eco class is Euro 6 on the 388 hp 3.0 AT and not measured on the 394 hp 3.0 AT.
Alpina XD4 specs and engine: both versions named 3.0 AT
Exact names from the database (do not rename):
| Version | Years | hp | kW | Nm | cm³ | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 3.0 AT (388 hp) | 2018-01-01–2021-05-31 | 388 | 285 | 770 | 2993 | Diesel | 6 | Inline | Turbo | Automatic, 8 | AWD |
| 3.0 AT (394 hp) | 2021-06-01, stop not measured | 394 | 289 | 800 | 2993 | Diesel | 6 | Inline | Turbo | Automatic, 8 | AWD |
Power band: 4000–5000 rpm on both 3.0 AT. Torque band: 1750–3000 rpm on both.
Power per litre and torque per litre
Displacement is 2993 cm³ on both, so specific output is a clean comparison.
- 3.0 AT 388 hp: 388 / 2.993 ≈ 129.6 hp/L; 285 kW / 2.993 ≈ 95.2 kW/L; 770 / 2.993 ≈ 257.3 Nm/L.
- 3.0 AT 394 hp: 394 / 2.993 ≈ 131.6 hp/L; 289 / 2.993 ≈ 96.6 kW/L; 800 / 2.993 ≈ 267.3 Nm/L.
The restyling 3.0 AT is +2.0 hp/L, +1.4 kW/L, +10.0 Nm/L. Relative to the first 3.0 AT: +1.5% power (6/388), +1.4% kW (4/285), +3.9% torque (30/770). The extra output is mostly torque, not peak horsepower.
Queries such as alpina xd4 hp and alpina xd4 engine resolve to these two peaks only: 388 hp or 394 hp, both Diesel Turbo Inline 6.
Performance: same 4.6 s and 268 km/h, different weight per horsepower
0–100 km/h is 4.6 s on 3.0 AT 388 hp and 4.6 s on 3.0 AT 394 hp. Maximum speed is 268 km/h on both. The catalogue does not show a sprint or top-speed gain for the restyling.
Kerb weight vs power:
- 3.0 AT 388 hp: 2045 kg / 388 hp ≈ 5.27 kg/hp (≈ 189.7 hp per tonne).
- 3.0 AT 394 hp: 2145 kg / 394 hp ≈ 5.44 kg/hp (≈ 183.7 hp per tonne).
The later car is +100 kg kerb (+4.9%) against +6 hp (+1.5%). Specific mass got worse by about 0.17 kg/hp. That is why 0–100 stays 4.6 s: the restyling 3.0 AT is stronger on paper and heavier in the same data.
Gross weight: 2550 kg (388 hp) vs 2560 kg (394 hp), only +10 kg. Payload (gross minus kerb):
- 3.0 AT 388 hp: 2550 − 2045 = 505 kg.
- 3.0 AT 394 hp: 2560 − 2145 = 415 kg.
The restyling 3.0 AT has 90 kg less payload. If you load people and cargo near the limit, the earlier 3.0 AT is the stronger number.
MPG and CO2: the 388 hp 3.0 AT uses less fuel in these figures
Consumption is L/100 km in the source (not US mpg).
| Version | City | Highway | Mixed | CO2 | Eco class | Tank |
|---|---|---|---|---|---|---|
| 3.0 AT (388 hp) | 7.8 | 6.3 | 6.9 | 183 | Euro 6 | 68 L |
| 3.0 AT (394 hp) | 8.3 | 6.4 | 7.1 | 187 | not measured | 68 L |
Deltas, restyling minus first 3.0 AT: city +0.5, highway +0.1, mixed +0.2 L/100 km, CO2 +4 g/km.
Tank range on mixed (68 L, arithmetic only):
- 3.0 AT 388 hp: 68 / 6.9 × 100 ≈ 986 km.
- 3.0 AT 394 hp: 68 / 7.1 × 100 ≈ 958 km.
About 28 km less mixed range on the same 68 L tank. Highway-only range: 68 / 6.3 × 100 ≈ 1079 km vs 68 / 6.4 × 100 ≈ 1063 km (−16 km). City: 68 / 7.8 × 100 ≈ 872 km vs 68 / 8.3 × 100 ≈ 819 km (−53 km). The city gap is the largest of the three.
If fuel and CO2 decide the buy, the 2 generation 3.0 AT 388 hp is the lower-consumption, Euro 6 row. The restyling 3.0 AT 394 hp is the higher-torque row with eco class not measured.
Dimensions and weight: what actually changed
Ground clearance: not measured on both 3.0 AT — it is not a selector in this catalogue.
Wheels: 255/45 R20 and 285/40 R20 on both. Tyre size does not split the choice.
Tank: 68 L on both.
| Version | Kerb, kg | Gross, kg | Payload, kg | Clearance |
|---|---|---|---|---|
| 3.0 AT (388 hp) | 2045 | 2550 | 505 | not measured |
| 3.0 AT (394 hp) | 2145 | 2560 | 415 | not measured |
The restyling 3.0 AT is the heavier kerb car. Gross barely moves. Suspension and brakes are the same English labels on both: Independent, spring; Ventilated disc / Disc ventilated.
Which Alpina XD4 version to choose
There are only two catalogue versions, both called 3.0 AT. Distinguish them by power: 388 hp vs 394 hp. There is no petrol Alpina XD4, no other gearbox, no other drive in these data. Alpina XD3 vs XD4 is a frequent search; this data set has no XD3 numbers, so that comparison is not measured here.
Buy the 2 generation 3.0 AT (388 hp) if you want the lighter kerb (2045 kg), higher payload (505 kg), lower mixed use (6.9 vs 7.1), lower city use (7.8 vs 8.3), lower CO2 (183 vs 187), Euro 6 on the card, and the same 4.6 s / 268 km/h. You give up 6 hp and 30 Nm. Production ended 2021-05-31, so this is the used-window car, not a current-production row.
Buy the 2 generation restyling 3.0 AT (394 hp) if you want the later car (from 2021-06-01, including a 2022 Alpina XD4 in calendar terms) and the higher Diesel torque (800 Nm vs 770 Nm). You pay in mass: +100 kg kerb, +0.17 kg/hp, −90 kg payload, +0.2 L/100 km mixed, +4 g/km CO2, eco class not measured. Sprint and top speed do not improve in the data.
What the later 3.0 AT “buys” in arithmetic: +6 hp, +4 kW, +30 Nm, +2.0 hp/L, +10.0 Nm/L, and an open end date. It does not buy a faster 0–100, a higher 268 km/h, a larger 68 L tank, different wheels, different AWD/Automatic 8 layout, or measured ground clearance. Relative to the first 3.0 AT, torque rose more than power, while kerb rose more than power, so weight per horsepower went the wrong way for a lighter feel.
UK / for-sale wording: searches such as alpina xd4 uk, alpina xd4 for sale uk, bmw alpina xd4 for sale, and alpina xd4 mobile de are listing queries. Prices are not in this data. Filter listings by the two 3.0 AT peaks: 388 hp and 770 Nm for 2018-01-01–2021-05-31; 394 hp and 800 Nm from 2021-06-01.
Reliability / problems: not measured in this data. Do not treat a missing problems section as “no faults.”
Review in one line from the numbers: the Alpina XD4 choice is not engine family vs engine family; it is whether 30 Nm and a later build date are worth 100 kg, 90 kg of payload, and 0.2 L/100 km mixed against an identical 4.6 s and 268 km/h 3.0 AT Diesel AWD Automatic.
