What are the pros and cons of the BMW X3?
The BMW X3's strengths are its model-specific performance and practicality; its trade-offs are size, complexity and the cost of high-specification variants.
Strengths
- The G45 earned five Euro NCAP stars in 2025, with the rating applying to the 20, 20d, 30e, 40d and M50 variants.
- The 570-litre combustion-model boot is square and expands to 1,700 litres; the 30e trades 110 litres for its battery.
- The 20d combines 197 hp, xDrive and a 2,500 kg maximum braked towing figure.
Weaknesses
- At 1,920 mm wide before mirrors, the G45 needs more care in older Luxembourg car parks than an X1.
- The 30e loses boot volume and only makes sense when it can be charged regularly.
- Large wheels and matched xDrive tyres make replacement costs materially higher than on a mainstream SUV.
Good to know before buying
- G01 diesels from the affected production windows should have proof that the BMW EGR-cooler campaign was completed.
- Check all four tyres for matching brand, model and similar tread depth because xDrive is sensitive to rolling-circumference differences.
- The G45 uses BMW Operating System 9; test profiles, phone pairing, cameras and driver-assistance functions before purchase.

What are the BMW X3 generations?
The current BMW X3 is coded G45. Luxembourg listings mainly span G45, G01, F25, whose platforms and powertrains should not be mixed when comparing specifications.
| Generation | Code | Years | Key change vs previous | Listings |
|---|---|---|---|---|
| 4th generation | G45 | 2024-present | Neue Klasse-inspired cockpit, 48V engines and a 30e plug-in hybrid | View G45 listings |
| 3rd generation | G01 | 2017-2024 | CLAR platform, wider cabin and the first X3 xDrive30e PHEV | View G01 listings |
| 2nd generation | F25 | 2010-2017 | More rear space, broader four- and six-cylinder range and standardised xDrive availability | View F25 listings |
| 1st generation | E83 | 2003-2010 | Original compact BMW SAV with mechanical xDrive and firmer road-focused chassis | View E83 listings |
The G01 is the value choice because it combines a conventional iDrive controller with a broad engine range. The G45 is roomier and more efficient, but its screen-led controls and higher used price require a careful test drive. A regularly charged 30e suits short mixed journeys; motorway-heavy users are better served by the 20d.
Which BMW X3 engine should you choose?
The X3 20d xDrive is the most balanced used choice for mixed Luxembourg and motorway driving; choose the 30e only with dependable charging.
| Engine types available | Petrol, Diesel, Mild hybrid, Plug-in hybrid |
|---|---|
| Engine codes | B48/B58 petrol, B47/B57 diesel; integrated electric motor on 30e |
| Power range | 190-398 hp (140-293 kW) |
| Transmission / drivetrain | 8-speed Steptronic; xDrive on current European models |
| 0-100 km/h | 4.6-8.5 seconds |
| Combined consumption | 6.5-8.3 l/100 km; 0.9-1.1 l/100 km weighted for 30e (WLTP) |
| CO2 emissions | 149-189 g/km; 21-26 g/km for 30e |
| Boot volume | 570 / 1,700 litres; 460 / 1,600 litres on 30e |
| Towing capacity | 2,000-2,500 kg braked, variant-dependent |
| Length / Width / Height | 4,755 / 1,920 / 1,660 mm (G45) |
| Wheelbase | 2,865 mm |
The 20d has enough torque for a loaded family car and can tow up to 2,500 kg in the specified G45 configuration. The 30e offers 299 hp and useful electric commuting, but its boot falls to 460 litres. The M50 is much faster, yet its 398 hp, tyres, brakes and insurance move it into a different running-cost bracket.
What are common BMW X3 problems?
The X3 has several VIN-specific campaigns rather than one fault affecting every car. The most important documentary check is completion of the EGR-cooler action on affected F25/G01 diesels.
- EGR cooler — F25/G01 four-cylinder diesels built April 2015-September 2016 and six-cylinder diesels built July 2012-June 2015, 2012-2016. Coolant could leak inside the EGR module, mix with deposits and in rare cases create a fire risk. Confirm campaign completion by VIN. BMW / EU documented campaign information
- Brake vacuum pump lubrication — Selected F25 X3 xDrive28i vehicles, 2012-2013. A BMW campaign addressed restricted vacuum-pump lubrication that could increase brake-pedal effort. Coverage is VIN-specific. BMW / EU documented campaign information
What to check before buying
- Match the VIN against BMW’s live recall checker and request invoices for completed campaigns.
- On a cold diesel, look for coolant loss, warning messages or exhaust smell around the EGR system.
- Drive slowly on full steering lock and listen for transfer-case shudder; also confirm four closely matched tyres.
- Test the panoramic roof drains, powered tailgate, cameras, iDrive and every driver-assistance warning.
What does a BMW X3 cost to run in Luxembourg?
Running costs for a BMW X3 in Luxembourg depend heavily on homologated CO2, tyres, brakes and equipment. The road-tax numbers below are estimates, not invoice amounts.
Taxe sur les véhicules automoteurs (annual road tax)
| X3 20d xDrive (approx. 156 g/km diesel) | approx. €225 per year (estimate) |
|---|---|
| X3 20 xDrive (approx. 170 g/km petrol) | approx. €230 per year (estimate) |
| X3 30e xDrive (approx. 24 g/km weighted) | approx. €30 per year (estimate) |
| X3 M50 xDrive (approx. 189 g/km petrol) | approx. €290 per year (estimate) |
Basis: official Luxembourg CO2-based passenger-car tax method applied to representative homologated values. Minimum charges and the exact registration-certificate value can change the result; estimates only.
Servicing
Basis: BMW Condition Based Service documentation; vehicle-specific due items take precedence.
Real-world consumption
Basis: qualified mixed-use estimates, kept separate from the WLTP homologation figures above.
What are the best alternatives to the BMW X3?
These four alternatives cover the BMW X3's main use case but differ in space, driving character or electrification.
| Model | Body | Powertrains | Boot (l) | Euro NCAP | Key difference |
|---|---|---|---|---|---|
| BMW X3 | Five-door SUV | Petrol, Diesel, Mild hybrid, Plug-in hybrid | 460-570 | 5 stars (G45, 2025) | |
| Audi Q5 | SUV | Petrol, diesel, PHEV | 520 | 5 (2017) | A calmer ride and familiar controls, but less boot space than the combustion X3. |
| Mercedes GLC | SUV | Petrol, diesel, mild hybrid, PHEV | 470-620 | 5 (2022) | Comfort-led cabin and strong PHEV range; screen-heavy controls are also prominent. |
| Volvo XC60 | SUV | Petrol mild hybrid, PHEV | 468-483 | 5 (2017) | More understated and safety-focused, with less sporting steering. |
| Porsche Macan | SUV | Petrol or electric, generation-dependent | 480-540 | 5 (2024 EV) | Sharper handling and higher costs; the latest generation is electric-only in Europe. |

Which used BMW X3 should you buy?
Frequently asked questions about the BMW X3
How safe is the BMW X3?+
The BMW X3 result is 5 stars (G45, 2025). Check the exact generation because protocols and standard equipment change over time.
What is the boot capacity of the BMW X3?+
The relevant BMW X3 capacities are 570 / 1,700 litres; 460 / 1,600 litres on 30e. Powertrain and body style can change the usable space, so confirm the exact variant rather than relying on a range-wide figure.
Which BMW X3 engine is best for daily driving?+
X3 20d xDrive is the starting recommendation for the use described here. Short urban trips, annual motorway mileage, towing and charging access can justify a different engine.
Is the BMW X3 available as a hybrid or electric car?+
Yes, the BMW X3 range includes plug-in-hybrid versions. Compare boot space, charging behaviour and homologated data for the precise version.
How should a BMW X3 be serviced?+
BMW uses Condition Based Service on the BMW X3, so the car displays due items according to time, distance and monitored wear rather than one universal interval. Follow the vehicle-specific service record and verify brake fluid, filters, plugs or diesel items separately.
Is the BMW X3 better than the Audi Q5?+
Neither is better in every respect. The BMW X3 emphasises BMW’s driving position and powertrain tuning, while the Audi Q5 offers a different balance of cabin layout, ride and practicality; compare equivalent generations and engines.
Can I import a BMW X3 from Germany or Belgium?+
Yes, an EU-market BMW X3 can be registered in Luxembourg when its purchase, registration, conformity and tax documents are in order. Check VIN campaigns, equipment, homologated CO2 and service history before purchase because these affect registration and ownership costs.
