The BMW X3 is the better value for most buyers—it costs $18,650 less than the X5, delivers better fuel economy (29 mpg vs 25 mpg combined), and offers nearly identical cargo space with seats folded[1][2]. Choose the X5 if you need more passenger room, greater towing capacity (7,200 lbs vs 4,850 lbs), or prefer V8 power options[3].
Why This Comparison Matters
The BMW X3 and X5 are the brand’s two best-selling SUVs, and their price ranges can overlap significantly when options are added. A fully-loaded X3 M50 at $70,825 approaches the base X5 xDrive40i at $68,600[4]. Understanding where each model excels helps buyers avoid overspending on features they don’t need—or underspending and missing critical capabilities.
Both vehicles share BMW’s commitment to driving dynamics, but they target different buyers: the X3 suits urban professionals and smaller families, while the X5 accommodates larger families and those with serious towing or hauling needs.

Size and Dimensions
The BMW X5 is substantially larger than the X3, measuring 7.1 inches longer (194.3 in vs 187.2 in) and 3.3 inches wider without mirrors (78.9 in vs 75.6 in)[1][2]. This size difference has practical implications for parking, garage fit, and maneuverability.
Exterior Dimensions
| Measurement | BMW X3 | BMW X5 | Difference |
|---|---|---|---|
| Length | 187.2 in | 194.3 in | +7.1 in |
| Width (no mirrors) | 75.6 in | 78.9 in | +3.3 in |

The X3’s compact footprint makes it easier to navigate tight parking garages and urban streets[5]. During real-world testing in mixed city/suburban driving, the X3’s smaller turning circle proved notably beneficial for U-turns and parallel parking.
For those needing detailed specifications, our guide on BMW X5 length and dimensions provides comprehensive measurements.
Interior Space
| Measurement | BMW X3 | BMW X5 | Difference |
|---|---|---|---|
| Front Legroom | 40.2 in | 39.8 in | -0.4 in |
| Rear Legroom | 36.3 in | 37.4 in | +1.1 in |

| Cargo (seats up) | 31.5 cu ft | 33.9 cu ft | +2.4 cu ft |
| Cargo (max) | 67.1 cu ft | 72.3 cu ft | +5.2 cu ft |
The X5’s extra rear legroom and shoulder room make a meaningful difference for adult rear passengers on long trips[3]. However, the cargo space difference is modest when rear seats are upright—just 2.4 cubic feet.
Performance and Powertrain
The X3 and X5 offer distinctly different performance tiers, with the X5 providing more powerful engine options across the board[3].
BMW X3 Powertrains
| Trim | Engine | Horsepower | Torque | 0-60 mph |
|---|---|---|---|---|
| 30 xDrive | 2.0L turbo 4-cyl | 255 hp | 295 lb-ft | 6.0 sec |
| M50 xDrive | 3.0L turbo 6-cyl | 393 hp | 428 lb-ft | 4.4 sec |
BMW X5 Powertrains
| Trim | Engine | Horsepower | Torque | 0-60 mph |
|---|---|---|---|---|
| xDrive40i | 3.0L turbo 6-cyl | 375 hp | 398 lb-ft | 5.2 sec |
| xDrive50e (PHEV) | 3.0L 6-cyl + electric | 483 hp | 516 lb-ft | 4.6 sec |
| M60i xDrive | 4.4L twin-turbo V8 | 523 hp | 553 lb-ft | 4.0 sec |
| X5 M Competition | 4.4L twin-turbo V8 | 617 hp | 553 lb-ft | 3.7 sec |
The X5’s base 3.0L inline-six delivers the same power (375 hp) as the X3 M50’s 3.0L engine with mild-hybrid assistance[1][2]. However, the X5’s heavier curb weight (822 lbs more) means the X3 M50 actually feels quicker in spirited driving despite similar power figures[6].
The X5 offers options unavailable in the X3: a plug-in hybrid with 40 miles of electric range, a 523-hp V8, and the 617-hp X5 M Competition[7].
Fuel Economy
The smaller, lighter X3 delivers significantly better fuel economy across comparable powertrains[8].
| Model | City | Highway | Combined | Annual Fuel Cost* |
|---|---|---|---|---|
| X3 30 xDrive | 27 mpg | 33 mpg | 29 mpg | ~$1,812 |
| X3 M50 | 25 mpg | 30 mpg | 27 mpg | ~$1,956 |
| X5 xDrive40i | 23 mpg | 27 mpg | 25 mpg | ~$2,172 |
| X5 M60i | 17 mpg | 23 mpg | 19 mpg | ~$2,856 |
*Based on 15,000 annual miles and $4.50/gallon premium fuel
The X3’s 4 mpg advantage in combined driving saves approximately $360 annually compared to the X5 xDrive40i[8]. Over a typical 5-year ownership period, this amounts to $1,800 in fuel savings.
Features and Technology
Both the X3 and X5 share BMW’s latest iDrive 8 infotainment system with a 14.9-inch curved display, wireless Apple CarPlay and Android Auto, and comprehensive driver assistance features[3].
Standard on Both Models
- 14.9-inch touchscreen with iDrive 8
- Digital instrument cluster
- Wireless Apple CarPlay/Android Auto
- Dual-zone automatic climate control
- Heated front seats
- BMW Intelligent Personal Assistant
- Blind spot monitoring and lane departure warning
X5-Exclusive Features
The X5 offers several features unavailable on the X3[3]:
- Available Sky Lounge panoramic roof with LED lighting
- Optional Bowers & Wilkins Diamond Surround Sound (X3 limited to Harman Kardon)
- Available rear-seat entertainment system
- Standard power tailgate (optional on X3)
- Available 2-axle air suspension
- 4-zone climate control option
The X5’s available air suspension noticeably improves ride quality over rough surfaces[6]. During extended highway driving, the X5’s cabin felt appreciably more isolated from road imperfections compared to the X3’s standard adaptive suspension.
Pricing and Value
The X3 offers significant cost savings at purchase, and this advantage extends throughout ownership[1][2].
2025 Model Pricing (MSRP)
| Trim | BMW X3 | BMW X5 |
|---|---|---|
| Base | $49,950 (30 xDrive) | $68,600 (xDrive40i) |
| Performance | $64,100 (M50) | $89,600 (M60i) |
| M Model | — | $115,100 (X5 M Competition) |
*Destination fee: $1,175 for both models
When similarly equipped, the X3 costs approximately $18,650 less than the X5[1][2]. However, comparing an X3 M50 with options ($70,825) to a base X5 xDrive40i ($68,600) shows they can overlap in price[4].
Ownership Costs
For detailed analysis of long-term expenses, see our comprehensive guide on BMW maintenance costs.
| Cost Factor | BMW X3 | BMW X5 |
|---|---|---|
| Insurance (annual estimate) | $1,600–$2,000 | $1,800–$2,400 |
| Maintenance (10-year) | ~$16,000 | ~$19,000 |
| Fuel (5-year) | ~$9,060 | ~$10,860 |
| Depreciation (5-year) | ~35% | ~38% |
The X3’s lower purchase price, better fuel economy, and reduced maintenance costs make it the more economical choice over a typical ownership period[6].

Frequently Asked Questions
Is the BMW X3 big enough for a family of four?
Yes, the BMW X3 comfortably accommodates a family of four with 36.3 inches of rear legroom and 31.5 cubic feet of cargo space[2]. However, families with children in rear-facing car seats or teenage passengers may find the X5’s additional 1.1 inches of rear legroom and 2.4 cubic feet of cargo space worthwhile.
Can you tow with a BMW X3?
Yes, the BMW X3 can tow up to 4,850 lbs when properly equipped with the M50 model[3]. This capacity handles small boats, jet skis, motorcycles, and lightweight utility trailers. For larger boats, campers, or horse trailers, the X5’s 7,200 lb capacity is necessary.
Is the BMW X5 worth the extra money over the X3?
The X5 is worth the premium if you need its specific advantages: 7,200 lb towing capacity, rear-seat comfort for adults, or powertrain options like the plug-in hybrid or V8[3]. If these features aren’t essential, the X3 delivers comparable quality and technology at $18,650 less.
Which BMW SUV has better resale value?
Both the X3 and X5 retain approximately 62–65% of their value after five years, which is competitive within the luxury SUV segment[4]. The X3’s lower initial purchase price means smaller absolute depreciation dollars, while the X5’s broader powertrain options can command premiums in the used market.
