In this comprehensive guide we’ll compare the size of the BMW X3 and BMW X5 highlighting both the benefits and potential drawbacks of each vehicle to help you make an informed decision. We’ll explore everything from exterior dimensions and interior space to driving dynamics. By the end of this article you’ll have a clear understanding of how these two popular models stack up.

Overview of the BMW X3 and BMW X5

The BMW X3 and BMW X5 are two SUVs in BMW’s lineup that cater to different kinds of drivers. While both vehicles share a similar design language the X3 is a compact luxury SUV while the X5 is a mid-size luxury SUV. This difference in class reflects their size weight and overall presence on the road.

BMW X3:

• Category: Compact luxury SUV
• Starting Price: Around $47,000
• Engine Options: Inline 4-cylinder and Inline 6-cylinder engines
• Seating Capacity: Up to 5 passengers

BMW X5:

• Category: Mid-size luxury SUV
• Starting Price: Around $66,000
• Engine Options: Inline 6-cylinder and V8 engines
• Seating Capacity: Up to 7 passengers with optional third row

Size Comparison: Exterior Dimensions

One of the most important considerations when choosing between the BMW X3 and BMW X5 is size. While both models offer the commanding road presence you expect from an SUV the X5 is noticeably larger.

Exterior Dimensions of the BMW X3

• Length: 185.9 inches
• Width: 74.4 inches (without mirrors)
• Height: 66.0 inches
• Wheelbase: 112.8 inches

Exterior Dimensions of the BMW X5

• Length: 194.3 inches
• Width: 78.9 inches (without mirrors)
• Height: 69.0 inches
• Wheelbase: 117.1 inches

As you can see the BMW X5 is about 9 inches longer and 4.5 inches wider than the BMW X3. It also has a slightly taller stance which contributes to its more imposing appearance on the road.

Pros of BMW X5's Larger Size

1. More road presence: The larger size of the X5 gives it a commanding look.
2. Greater interior space: We'll discuss this in detail below but the X5's size translates to a more spacious cabin.
3. Third-row seating: Available in the X5 which is not an option in the X3.

Drawbacks of the BMW X5's Size

1. Parking: The larger footprint can make parking in tight spaces a challenge especially in urban areas.
2. Fuel efficiency: A larger SUV generally means lower fuel efficiency compared to smaller models.
3. Price: The bigger size also means a bigger price tag. The X5 starts significantly higher than the X3.

Interior Space: Passenger Comfort

The interior space of an SUV is crucial for family trips long drives or even just daily commutes. Let's compare the passenger space offered by both the BMW X3 and BMW X5.

BMW X3 Interior Dimensions

• Front Headroom: 41.1 inches
• Rear Headroom: 39.1 inches
• Front Legroom: 40.3 inches
• Rear Legroom: 36.4 inches

BMW X5 Interior Dimensions

• Front Headroom: 40.8 inches
• Rear Headroom: 39.4 inches
• Front Legroom: 39.8 inches
• Rear Legroom: 37.4 inches

While the X5 is bigger on the outside the interior space is not vastly different at least for the first two rows. Both models offer plenty of headroom and legroom for passengers but the X5 does offer a little more rear legroom which can make a difference on long trips.

However the X5 has the added advantage of an optional third row of seats. While this third row is more suitable for kids or shorter adults it’s a valuable feature for larger families or those who frequently have extra passengers.

Pros of BMW X3's Interior Space

1. Ample space for 5 passengers: Even though it’s smaller the X3 still offers plenty of room for a family of five.
2. Cozy and compact feel: Some people prefer a snugger more car-like driving experience which the X3 provides.

Drawbacks of the BMW X3's Interior Space

1. No third-row option: If you need to seat more than 5 passengers the X3 won't work for you.
2. Less rear legroom: Taller passengers in the back seat may feel a bit cramped on long drives compared to the X5.

Cargo Space Comparison

Cargo space is another critical factor especially if you're considering an SUV for road trips or hauling gear.

BMW X3 Cargo Capacity

• Cargo Space Behind Second Row: 28.7 cubic feet
• Cargo Space with Seats Folded: 62.7 cubic feet

BMW X5 Cargo Capacity

• Cargo Space Behind Second Row: 33.9 cubic feet
• Cargo Space with Seats Folded: 72.3 cubic feet

The BMW X5 once again takes the lead when it comes to cargo capacity. With the second row up it offers about 5 more cubic feet of space than the X3. When you fold down the rear seats the difference becomes even more pronounced with the X5 offering about 10 cubic feet more than the X3.

Benefits of BMW X5's Cargo Space

1. More room for gear: Perfect for long road trips or outdoor activities.
2. Power tailgate: Standard on the X5 making loading and unloading easier.

Drawbacks of the BMW X5's Cargo Space

1. Bulkier to maneuver: With the added cargo space comes a larger vehicle that can feel more cumbersome in tighter areas.

Driving Dynamics and Performance

When it comes to driving dynamics both the BMW X3 and X5 deliver the sporty handling BMW is known for but they do so in different ways due to their size and engine options.

BMW X3 Performance

• Base Engine: 2.0-liter inline-4
• Horsepower: 248 hp
• 0-60 mph: 6.0 seconds
• Towing Capacity: Up to 4,400 lbs

BMW X5 Performance

• Base Engine: 3.0-liter inline-6
• Horsepower: 335 hp
• 0-60 mph: 5.3 seconds
• Towing Capacity: Up to 7,200 lbs

The BMW X5 offers significantly more power right out of the gate with its inline-6 engine and also has an available V8 engine for even more performance. The X3 by contrast starts with a 4-cylinder engine but offers a 6-cylinder engine in higher trims.

BMW X3 Driving Dynamics

1. Lighter and more agile: The X3’s smaller size makes it easier to maneuver in city traffic and tight spaces.
2. Great handling: For its class the X3 handles exceptionally well making it fun to drive on winding roads.

BMW X5 Driving Dynamics

1. More powerful engines: The X5 delivers more horsepower and better acceleration especially with the available V8 engine.
2. Smooth ride: Thanks to its air suspension (available on higher trims) the X5 offers a more comfortable ride over rough roads.

Fuel Efficiency

Fuel efficiency is a big factor for many buyers especially as fuel prices fluctuate. Because the BMW X3 is smaller and lighter it tends to offer better fuel efficiency than the BMW X5.

BMW X3 Fuel Economy

• City: 23 mpg
• Highway: 29 mpg
• Combined: 25 mpg

BMW X5 Fuel Economy

• City: 21 mpg
• Highway: 26 mpg
• Combined: 23 mpg

While the BMW X3 is more fuel-efficient the X5 doesn’t lag too far behind considering its larger size and more powerful engine options.

Real-Life Testimonial: Alex Collantes Weighs In

Alex Collantes a seasoned car enthusiast shared his personal experience with both models. According to Alex "I’ve driven both the X3 and X5 extensively and while the X3 offers a more nimble ride especially in the city the X5 feels like the perfect road trip vehicle. The extra cargo space and more powerful engine make a huge difference for long drives."

He added "If you're mostly driving solo or with a small family the X3 is probably all you need. But if you’re hauling more people or need to tow anything heavy the X5 just makes more sense despite the higher price."

Pricing and Value for Money

When it comes to pricing the BMW X3 and X5 are in different leagues. The X3 is the more affordable option starting at around $47,000 while the X5 starts at about $66,000.

What You Get for the Price

• BMW X3: Offers great value for those who don’t need the extra space or power of the X5. It still provides the luxury features and performance you’d expect from BMW but at a lower cost.
• BMW X5: The higher starting price gets you more space more power and more luxury features. However it may be more than you need if you’re not planning on using the third row or taking advantage of the added power.

Conclusion: Which One Is Right for You?

Choosing between the BMW X3 and BMW X5 ultimately comes down to your personal needs. If you’re looking for a more compact SUV with great fuel efficiency and a lower starting price the X3 is likely the better choice. However if you need more space power and towing capacity the X5 is the clear winner.

Key Takeaways:

• X3 is better for city driving smaller families and those looking to save on fuel costs.
• X5 is ideal for larger families long road trips and those who need more towing capability or luxury features.

Final Thought:

As Alex Collantes puts it “Both the X3 and X5 are fantastic SUVs but it’s really about what you need. If you’re not using that extra space and power the X3 is plenty of car. But if you want something more substantial the X5 won’t disappoint.”

Both vehicles have their pros and cons and neither is a bad choice. But your final decision should depend on your lifestyle and what you need from an SUV.
