BMW X3 (G45 — Model-Year 2025)


After more than 3.5 million units sold, the fourth-generation X3 arrives with a “monolithic” design language, “Shy Tech” minimalist interior and an updated CLAR platform featuring standard 48 V mild-hybrid technology. The body grows by 34 mm in length and 29 mm in width (now 4 755 × 1 920 × 1 669 mm; wheel-base 2 865 mm). A powered tail-gate, Adaptive LED headlights (Matrix standard on M Sport) and the iDrive 9 curved display (14.9 in) with Panoramic Vision HUD are standard highlights.

PRO

PROWhy it stands out
Top-class space & flexibility40/20/40 sliding rear bench, flat floor, 570 L boot; new rail system with hooks and 12 V socket.
Broad powertrain menuDiesels for high-milers, balanced 20 xDrive mild-hybrid, 90 km-EV 30e plug-in, and the hot-hatch-quick M50.
Sharper dynamicsStandard adaptive suspension (M Adaptive Pro on M50), variable steering and +19 mm tracks cut roll by 8 %.
iDrive 9 infotainmentCurved Display + full-width AR HUD, “Hey BMW” voice and smartphone-style QuickSelect tiles.
Level 2+ driver aids210 km/h adaptive cruise, assisted lane change, remote parking; “Personal Pilot” L3 hardware on standby.
Real-world efficiency20d holds 5.3 L/100 km on motorway; 30e delivers 50–55 km EV even in winter.
Strong resaleX models are fleet favourites: 40d and 30e M Sport retain ~72 % of MSRP after three years.

CON

CONTypical comment
High mass (30e 1 970 kg)Battery raises centre of gravity; feels less agile than 20 xDrive.
Firm 21-inch M Sport wheels245/40-21 tyres transmit urban potholes; 20-inches ride better.
Pricey optionsCrystal Iconic Glow, AR HUD, B&W Diamond add €9–10 k to a base 20 xDrive.
Touch-only climateAwkward with gloves; iDrive rotary stays but no physical HVAC knobs.
I6 petrol oil useM50 needs ~0.6 L top-up every 4 000 km under spirited driving.
DC >50 kW essential for PHEV30e charges at 7.4 kW AC or 50 kW DC—slow chargers hurt long trips.

Verdict — BMW X3 (G45 MY 2025)

The fourth-generation X3 grows in size, adds standard mild-hybrid powertrains and a “tech-lounge” cabin with iDrive 9, yet keeps its well-rounded BMW DNA. In the crowded mid-size premium field (Audi Q5, Mercedes-Benz GLC, Volvo XC60, Lexus NX, Alfa Romeo Stelvio) no single model rules every category; the X3’s strength is its balance of space, driving feel and power-train choice. Here’s a critical rundown across ten key areas.

AreaWhere it leadsWhere it matchesWhere it trails
Design & image“Monolithic” lines, Iconic Glow grille, sharper M Sport kit than GLC.Standard Veganza trims are respectable.Cabin less flamboyant than GLC Hyperscreen or Volvo XC60’s portrait display.
Dynamics+19 mm tracks, variable steering, standard adaptive chassis: 8 % less roll; M50 does 0-100 km/h in 4.6 s.Stable braking, though long pedal travel on 20i/20d.At 1 970 kg the M50 feels less agile than Stelvio Veloce in tight bends.
Real-world efficiency20d at 5.3 L/100 km motorway; 30e ≈ 19 kWh/100 km in city EV mode.20 xDrive equals Q5 45 TFSI.40d drinks 0.5 L/100 km more than GLC 300d MHEV.
Charging experience30e battery pre-conditioning, HPC route planner via iDrive 9.50 kW DC: 27 min 10→80 %.Rivals with 60 kW+ (Stelvio REplug-in) or faster AC aren’t far behind.
Comfort & NVH67 dB at 130 km/h (acoustic glass); engine vibrations well suppressed.M Adaptive Pro on M50 excels.21-inch run-flats ride harsher than Q5 on air springs.
HMI / InfotainmentiDrive 9 boots < 3 s, QuickSelect tiles intuitive, panoramic AR HUD optional.iController remains.GLC Hyperscreen & Google-based XC60 look more “wow”.
Practicality570 L boot, bench slides 135 mm: class-leading.Big doors, low load lip.30e loses 100 L; no frunk.
Running costsService Inclusive 5 yr/60 k km at €990; 20d enjoys lower road tax.Standard 20-inch tyres €250 each.M50: 21-inch rubber €320 each + oil top-ups → TCO +11 % vs 40d.
Depreciation40d & 30e M Sport predicted ≥ 72 % after 36 mo.M50 projected 68 %.GLC diesels hold slightly better due to lower entry price.
Range & incentivesPetrol, diesel, PHEV in one body style; eco-bonuses on 30e in some regions.No full-electric yet (future Neue-Klasse iX3).

Who it suits

  • Active families needing space, AWD and low running costs (20d/20 xDrive).

  • Commuters with home charging: 30e delivers up to 90 km EV and tax perks.

  • High-mileage business users: motorway comfort, full ADAS, strong resale.

  • Light-M enthusiasts: M50 offers hot-hatch pace with SUV versatility.

Who should look elsewhere

  • Fast-charge EV travellers requiring >150 kW DC – consider Audi Q6 e-tron, Tesla Model Y LR.

  • Display fanatics – opt for Mercedes GLC Hyperscreen or Volvo XC60 Google cockpit.

  • Air-suspension seekers for towing or plush ride – Audi Q5 on air, Range Rover Velar.

Recommended spec

X3 30e xDrive M Sport + Innovation Pack + 20-inch wheels: sweet balance of punch, nightly charging, incentives and ride comfort; skip the noisier 21-inch run-flats.


The 2025 X3 isn’t the lightest or the flashiest, yet it blends top-tier cabin space, engaging dynamics and power-trains for every need. For buyers wanting a well-rounded premium SUV with genuine AWD, modern tech and sensible running costs, the X3 remains one of the segment’s most complete propositions.
