BMW XM Review: High-Performance Plug-In Hybrid SUV Tested

content: The $160,000 Super SUV Dilemma

When shopping for ultra-high-performance SUVs like the Lamborghini Urus or Porsche Cayenne Turbo, BMW wasn't on the radar—until now. The 2023 BMW XM changes that as the brand's first standalone M Division SUV since the iconic M1 sports car. After testing this 644-horsepower plug-in hybrid, I discovered surprising strengths and critical trade-offs at this price point. Let's examine whether BMW's bold gamble pays off against established six-figure rivals.

Core Engineering and Performance Specifications

BMW's M Division engineered the XM as a ground-up performance machine, not a modified existing platform. Under the hood lies a 4.4L twin-turbo V8 paired with an electric motor, generating 644 horsepower and 590 lb-ft of torque. Independent testing by Car and Driver clocked a staggering 3.4-second 0-60 mph time—faster than BMW's 4.1-second claim. Power routes through an 8-speed automatic and standard all-wheel drive.

The plug-in hybrid system delivers 30 miles of electric-only range (up to 87 mph). EPA ratings sit at 14 MPG gas-only or 46 MPGe combined. For those craving more, the $185,000 XM Label Red bumps output to 738 horsepower.

Exclusive Design: Form Follows Function?

The XM's styling sparks intense debate. Its massive split kidney grille with illuminated outlines and sharp body creases create an aggressive, polarizing presence. After seeing it in person, I appreciate how darker colors mask busy lower body lines. Key dimensions reveal its purpose:

Feature	Specification
Wheelbase	Same as 3-row X7
Length	2.5" shorter than X7
Height	3" lower than X7
Wheels	Standard 23-inch alloys

The rear features stacked quad exhaust tips and prominent XM badging—noticeably absent are traditional BMW roundels on the tailgate. Functionality shines through with active aerodynamics, including functional front intakes for brake and engine cooling.

Luxury Interior With Compromises

Step inside, and the XM surrounds occupants with carbon fiber, metal trim, and quilted Merino leather. The curved display integrates a 12.3" digital cluster and 14.9" infotainment screen with wireless Apple CarPlay/Android Auto. Physical controls remain, including a volume knob and iDrive rotary.

Notable features:

• Heated/cooled massaging front seats (though massage function is underwhelming)
• Heated rear outboard seats
• Cup holders that heat or cool beverages
• Configurable M1/M2 steering wheel buttons for drive modes

Disappointments include the unintuitive gear selector and a fixed glass roof panel (no opening moonroof), making the cabin feel darker than competitors. Rear seats lack power recline despite the $160k price.

Driving Dynamics: Performance Meets Practicality

Behind the wheel, the XM's 6,000-pound weight disappears in corners thanks to active anti-roll bars and rear-wheel steering. The system counters body lean at high speeds and tightens low-speed maneuverability. Pushing hard on twisty roads reveals exceptional balance and grip, with the hybrid system delivering seamless power between the V8 and electric motor.

However, daily driving exposes flaws:

• Stiff ride quality from steel springs (no air suspension) and 23-inch wheels
• Throttle lag during moderate acceleration as the system decides between power sources
• Visibility challenges from thick rear pillars and the sloping roofline

Competitive Positioning and Value

The XM targets the Aston Martin DBX, Lamborghini Urus, Audi RS Q8, and Porsche Cayenne Turbo. Its plug-in hybrid system offers a unique advantage: silent electric commuting and explosive performance when needed. How key specs compare:

Model	HP	0-60 (sec)	Base Price
BMW XM	644	3.4*	$160,000
Lamborghini Urus	657	3.1	$239,000
Porsche Cayenne Turbo GT	631	3.1	$190,000

Final Verdict: Pros and Cons

Pros:

• Brutal acceleration with hybrid efficiency
• Flat cornering defying its weight
• Customizable M modes for personalized driving
• Practical cargo space (64 cu ft seats folded)

Cons:

• Unforgiving ride quality
• Throttle hesitation in daily driving
• Controversial styling won’t suit all tastes
• Missing luxury touches at this price

The XM succeeds as a statement vehicle that backs bold looks with legitimate performance. While rivals offer sharper dynamics, BMW’s plug-in hybrid approach brings unique flexibility. If you prioritize exclusivity and tech over ultimate ride comfort, it deserves a test drive.

Toolkit: Super SUV Buyer’s Checklist

1. Test ride quality on rough roads with 23” wheels
2. Verify charging access for daily EV use
3. Compare cargo space vs. Porsche Cayenne
4. Explore M1/M2 presets for one-touch driving modes
5. Negotiate included maintenance at dealership

Premium Alternatives:

• Porsche Cayenne Turbo E-Hybrid: Better ride, less power ($129,000)
• Audi RS Q8: Subtler styling, similar performance ($128,000)
• Lamborghini Urus Performante: Track-focused, $50k+ premium
