SUVs are BMW's most popular vehicles. And the X3 and X5 are BMW's most popular SUVs.

Why?

Because they include impressive spaces, features, speedy powertrains, lavish interiors, and modernized technology.

Also, unlike a lot of brands and models these days, new 2025 X3s and X5s are typically available.

That begs the question: which one is better?

BMW of Devon has the answer. Read on to find out!

Performance and Engine Options

BMW X3 Engine Specifications

The 2025 BMW X3 is equipped with a 2.0-liter inline 4-cylinder turbocharged engine, producing 255 horsepower. This engine allows the X3 to accelerate from 0 to 60 mph in approximately 6 seconds. For those seeking more power, the X3 M50 variant features a robust 3.0-liter inline 6-cylinder engine with 393 horsepower.

The M50 can go from 0-60 in 4.4 seconds. The X3 offers an 8-speed automatic transmission and comes standard with BMW's xDrive all-wheel drive system.

BMW X5 Engine Specifications

The 2025 BMW X5 offers a range of engine options - starting with a 3.0-liter inline 6-cylinder turbocharged engine that delivers 375 horsepower. It takes 5.3 seconds for it to go from 0-60.

For those seeking even more performance, the X5 M60i variant features a powerful 4.4-liter V8 engine with 523 horsepower. The top-of-the-line X5 M Competition's V8 engine can generate 617 horsepower and eclipse the 0-60 mark in 3.7 seconds.

Like the X3, the X5 includes an 8-speed automatic transmission and comes standard with BMW's xDrive all-wheel drive system. But unlike the X3, the 2025 X5 offers a plug-in hybrid model (X5 xDrive50e). The X5 PHEV gets up to 58 combined miles per gallon equivalent. That doubles the X3's maximum fuel efficiency, and more than doubles that of any other X5.

Interior Space and Comfort

Seating Capacity and Layout

Both the 2025 BMW X3 and X5 comfortably seat up to five passengers. However, the X5's interior dimensions are larger.

The X5 gives passengers 40.8 inches of front-row headroom. The X3's front-row headroom is 40.5 inches.

The X5 has 39.8 inches of legroom in the front and 37.4 inches in rear. The X3's legroom dimensions are 40.2 inches (front) - ironically more than the X5 - and 36.3 inches (rear).

That additional headroom and rear legroom enhances the overall luxury and comfort you'll feel inside the X5. This can significantly impact the overall passenger experience, particularly for families or those who often carry additional passengers.

The X3's cozier environment is great for two passengers and short family trips. And it's important to note that the 2025 X3 underwent a redesign that makes it over an inch longer and wider than previous years.

Cargo Capacity with Seats Folded

In terms of cargo capacity, the 2025 BMW X3 offers 62.7 cubic feet of space with the rear seats folded down. That's a lot of space for a compact SUV. But it pales in comparison to the X5. The 2025 X5 provides 72.3 cubic feet of total cargo space.

So, if you frequently transport large items like luggage, you'll be better off with an X5.

Both models have 40/20/40 split fold-down rear seat designs. This configuration comes in handy when carrying groceries, sports equipment, and other bulky items.

Features and Technology

Standard Audio and Infotainment Options

The 2025 BMW X5 boasts a 12.3" instrument cluster and 14.9" central information display.

Thanks to this year's redesign, the X3 also features a 14.9" central information display. Before 2025, the X3 had a 10.25-inch standard display.

Both luxury SUVs come with Apple CarPlay and Android Auto. However, the X5 has a standard HiFi sound system.

Safety Features Comparison

Safety remains BMW X3 and X5 priorities. Both models come standard with a comprehensive suite of advanced safety features. These include:

• Active Blind Spot Detection
• Lane Departure Warning
• Frontal Collision Warning with City Collision Mitigation
• Active Protection
• Active Driving Assistant
• Full LED Headlights

The 2024 BMW X3 and 2025 BMW X5 were both named a "Top Safety Pick+" by the Insurance Institute for Highway Safety. That is the highest rating a vehicle can achieve. Grades are based on crash test results and crash avoidance. 2025 X3 results are not yet available.

Pricing and Value

2025 BMW X3 and X5 Pricing Overview

The 2025 BMW X3 starts at $49,500 MSRP. That's for the base xDrive30 model. The X3 has one other trim level, the M50, that starts at $64,100 MSRP. Each come with standard all-wheel drive.

As the larger and more powerful SUV, the 2025 X5 starts at $65,700 MSRP. That's for the base sDrive40i, which is a two-wheel drive vehicle. Its all-wheel drive version, the xDrive40i, starts at $68,000 MSRP.

Pricing for the X5's three other trims are as follows:

• xDrive50e - $73,100 Starting MSRP
• M60i - $90,000 Starting MSRP
• M Competition - $124,800 Starting MSRP

Value for the Money

When comparing value for the money, the X3 offers a lower entry price and better fuel efficiency (excluding the X5 PHEV). That makes it the more cost-effective model.

The X5 provides greater luxury, performance, and space. If you prioritize those aspects in an SUV, the higher price is justified.

Conclusion and Recommendation

BMW X3 Best Use Cases

The 2025 X3 is best suited for individuals or small families who prioritize agility, efficiency, and a sporty driving experience. Its compact size makes it ideal for urban environments while still offering enough space for everyday needs.

The X3 is also a great choice for those looking for a luxury SUV with a modest price tag. Buyers who want a nimble vehicle that handles well in various driving conditions will love the X3.

BMW X5 Best Use Cases

The 2025 X5 is ideal for larger families or individuals who require more space and power. With its superior cargo capacity, advanced features, and powerful engine options, the X5 is better equipped for long trips and outdoor adventures.

It's also a better option for buyers who value luxury and are willing to invest in a premium vehicle.

Circling back to the question posed at the beginning - which is better, the X3 or X5? - the answer is ultimately up to you. Weigh their pros and cons against your needs and preferences.
