BMW X2

Generations compared: what each change actually moved

BMW X2 has 3 generations in this catalogue: 1 generation (2017-10-01 to 2020-04-30), 1 generation, restyling 1 (2020-05-01 to 2023-09-30), and 2 generation (2023-10-01, stop not measured). Body label is SUV 5-doors on all three.

BMW X2 has 3 generations in this catalogue: 1 generation (2017-10-01 to 2020-04-30), 1 generation, restyling 1 (2020-05-01 to 2023-09-30), and 2 generation (2023-10-01, stop not measured). Body label is SUV 5-doors on all three. Ground clearance is 182 mm on every first-generation and restyle version that lists it, then 207 mm on every second-generation version — a +25 mm step and the only clearance change in the data.

Engine layout in the data moves from Front, transverse (1 generation and restyling 1) to Front, longitudinal (2 generation). That is a recorded layout change, not an inferred chassis story.

The M line is the cleanest cross-generation pair. M35i 2.0 AT xDrive (1 generation): 306 hp, 225 kW, 450 Nm, 1998 cm³, Gasoline, 4 Inline, Turbo, Automatic 8, AWD, 0–100 km/h 5.0 s, 250 km/h, mixed 7.1 L/100 km, tank 51 L, CO2 161 g/km, Euro 6, kerb 1610 kg, gross 2190 kg. Restyling M35i xDrive Steptronic: still 306 hp, 225 kW, 450 Nm, 1998 cm³, Gasoline, 4 Inline, Turbo, AWD, 5.0 s, 250 km/h, kerb 1610 kg, gross 2190 kg — but gearbox is Robotic 7, tank is 61 L (+10 L vs the first M35i), mixed consumption not measured, CO2 not measured, eco class not measured, compression ratio not measured. Second-generation M35i xDrive Steptronic: 300 hp (−6 hp), 220 kW, 400 Nm (−50 Nm), Automatic 7, AWD, 5.1 s (+0.1 s), 250 km/h, mixed 7.7 L/100 km (+0.6 vs first-generation 7.1), tank 54 L (−7 vs restyle 61 L, +3 vs first 51 L), kerb 1695 kg (+85 kg), gross 2270 kg (+80 kg), CO2 not measured. Specific output: 153.2 hp/L on both 306 hp M35i versions, 150.2 hp/L on the 300 hp car.

Plug-in 25e 1.5 DCT xDrive is the other named pair. First generation: 125 hp, 91 kW, 220 Nm, 1499 cm³, Plug-in, 3 Inline, Turbo, Robotic 7, AWD, 6.8 s, 195 km/h, mixed 1.9 L/100 km, city/highway not measured, tank 51 L, CO2 43 g/km, Euro 6, kerb 1805 kg, gross not measured. Restyling: 220 hp (+95 hp), 161 kW, same 220 Nm, same 6.8 s and 195 km/h, mixed 1.7 L/100 km (−0.2), kerb 1730 kg (−75 kg), still gross not measured, eco class not measured. Power per litre jumps from 83.4 to 146.8 hp/L; kg/hp drops from 14.44 to 7.86. The 0–100 time does not change with the +95 hp on this sheet.

Entry petrol in restyling 1 keeps the name 18i 1.5 DCT sDrive twice: distinguish them by power. One is 136 hp / 100 kW / 224 Nm; the other is 140 hp / 102 kW / 220 Nm. Both: 1499 cm³, Gasoline, 3 Inline, Turbo, Robotic 7, FWD, 9.6 s, 205 km/h, 7.0 / 5.1 / 5.8 L/100 km, tank 51 L, CO2 133 g/km, Euro 6, kerb 1415 kg, gross 2005 kg. The 140 hp car is 4 hp up and 4 Nm down versus the 136 hp car; 0–100, top speed, consumption, weight, and tank are identical.

Engines and specs

Version names below are exactly as in the database.

All listed engines sit Front, transverse through restyling 1 and Front, longitudinal in 2 generation. Gasoline and Plug-in versions that list injection use Direct injection (direct); first-generation diesels list injection as not measured; restyle 1.5 AT and all second-generation versions list Direct injection (direct). Fuel grade: Gasoline/Plug-in 95, Diesel Diesel. Eco class: Euro 6 where measured; not measured on restyle M35i/25e and on the whole 2 generation.

First-generation 18d family: four versions share 150 hp / 110 kW / 350 Nm / 1995 cm³ / Diesel / 4 Inline / Turbo. The buyer is choosing gearbox and drive, not displacement. 18d 2.0 MT sDrive is Manual 6 FWD; 18d 2.0 AT sDrive Automatic 8 FWD; 18d 2.0 MT xDrive Manual 6 AWD; 18d 2.0 AT xDrive Automatic 8 AWD.

Which version to choose

If 0–100 time is the ranking key: M35i 2.0 AT xDrive or restyle M35i xDrive Steptronic (both 5.0 s, 306 hp, 1610 kg). Second-generation M35i xDrive Steptronic gives up 6 hp, 50 Nm, 0.1 s, and 85 kg of kerb weight, and raises mixed use from 7.1 to 7.7 L/100 km. What the later M35i adds on this sheet: 207 mm clearance (+25), Front, longitudinal layout, Automatic 7 instead of Automatic 8 or Robotic 7, tank 54 L. Restyle M35i is the 61 L tank car if range from tank size is the extra.

If mixed litres are the ranking key and a plug-in is acceptable: restyle 25e 1.5 DCT xDrive (1.7 L/100 km, 220 hp, 1730 kg, 6.8 s). First-generation 25e 1.5 DCT xDrive is the same 6.8 s with 125 hp, 1805 kg, 1.9 L/100 km — 95 hp less and 75 kg more for +0.2 L/100 km mixed. City and highway figures are not measured on either 25e.

If mixed litres without plug-in: first-generation 18d 2.0 MT sDrive at 4.6 L/100 km, 121 g/km CO2, 1500 kg, Manual 6, FWD, 9.3 s. Moving to 18d 2.0 AT sDrive keeps 150 hp and 9.3 s, adds Automatic 8, +35 kg, mixed 4.7 (+0.1), CO2 124 (+3). Moving to 18d 2.0 MT xDrive is AWD, 1580 kg (+80 vs MT sDrive), mixed 5.2 (+0.6), 9.2 s. 18d 2.0 AT xDrive is the heavy automatic AWD 18d at 1600 kg, 9.4 s, mixed 4.9. Restyle 1.5 AT undercuts those mixed figures at 4.3 L/100 km and 112 g/km, but 0–100 and top speed are not measured, and it is 116 hp / 270 Nm / 3 Inline Diesel FWD — the lowest power in the catalogue.

If diesel torque with more than 150 hp, first generation: 20d 2.0 AT is 190 hp, 400 Nm, 7.7 s, mixed 4.8, 1600 kg. 25d 2.0 AT xDrive is 231 hp, 450 Nm, 6.7 s, mixed 5.3 (+0.5 vs 20d), 1585 kg (15 kg lighter than 20d), 139 g/km versus 126. The 25d is the diesel that matches first-generation M35i torque (450 Nm) with 7.1 L/100 km petrol M35i versus 5.3 diesel.

If second-generation diesel: 18d Steptronic and 20d Mild Hybrid xDrive Steptronic share mixed 5.1 L/100 km and 80 L tanks. The 20d is +13 hp (163 vs 150), same 360 Nm, 8.6 s versus 8.9 s (−0.3 s), 207 versus 210 km/h, kerb 1705 versus 1600 kg (+105 kg). Drive field for both is FWD. Versus first-generation 20d 2.0 AT (190 hp, 7.7 s, mixed 4.8, 51 L, AWD), the later 20d is slower, thirstier on mixed, and FWD, with +29 L tank and +25 mm clearance.

If petrol without M, first generation: 18i 1.5 MT sDrive is the lightest (1395 kg) and the only Manual petrol. 18i 1.5 DCT sDrive (136 hp) is +20 kg, Robotic 7, same 9.6 s / 205 km/h / 5.8 mixed. 20i 2.0 DCT sDrive (190 hp) is 7.7 s, mixed 5.9, 1460 kg, FWD. 20i 2.0 AT xDrive (192 hp) is AWD, 1540 kg (+80 vs DCT sDrive), 7.4 s (−0.3 s), mixed 6.2 (+0.3), CO2 142 versus 134. Two horsepower and AWD cost 80 kg and 0.3 L/100 km mixed.

If petrol mild hybrid, second generation: the two 20i 1.5 DCT Mild Hybrid sDrive Steptronic cars. 170 hp: 8.3 s, mixed 6.6, tank 45 L, kerb 1570 kg, gross 2570 kg, wheels not measured. 156 hp: 9.0 s, mixed 6.7, tank 54 L, kerb 1490 kg (−80 kg), gross not measured, wheels 245/45 R19 and 245/40 R20 — the only wheel listing in the model. 28i 1.5 DCT Mild Hybrid sDrive Steptronic is the mid petrol: 241 hp, 400 Nm (same Nm as 2 generation M35i), 6.5 s, 240 km/h, mixed 6.7, 1725 kg, AWD, tank 54 L. Versus 2 generation M35i: −59 hp, same 400 Nm, +1.4 s, −10 km/h, −1.0 mixed L/100 km, +30 kg kerb.

If one car across generations with the same job: M35i is the only name that exists in all three generation rows (as M35i 2.0 AT xDrive then M35i xDrive Steptronic twice). 25e exists in 1 generation and restyling 1, not in 2 generation. 18i DCT exists in 1 generation and restyling 1. Diesel 18d/20d exist in 1 generation and 2 generation with different names and, in 2 generation, 80 L tanks and 207 mm clearance.

Problems and reliability

Problems, reliability, service intervals, and prices are not measured in this dataset. What is measured is the spec grid above: version names, power, torque, displacement, fuel type, cylinders, layout, boost, gearbox, drive, 0–100, top speed, consumption, CO2, weights, clearance, tank, and wheels. Where a cell is empty in the source, this article states not measured rather than filling it from elsewhere.
