2026 BMW M5: 717 HP Hybrid Super Sedan Review

The 2026 BMW M5 stands as a monumental achievement in performance sedans, fusing a potent plug-in hybrid powertrain with BMW’s signature driving dynamics. This G90-generation model boasts 717 horsepower from a twin-turbo 4.4-liter V8 paired with an electric motor, delivering supercar acceleration in a practical five-seat package.

Powertrain Revolution: V8 Meets Electric Boost

At the heart of the 2026 M5 lies a sophisticated plug-in hybrid system. The twin-turbocharged 4.4-liter V8 produces 577 horsepower on its own, augmented by a permanently excited electric motor adding significant torque for a combined 717 hp output. BMW claims a 0-60 mph sprint in just 3.4 seconds, though real-world tests suggest it could be quicker, echoing the previous non-hybrid M5’s 2.9-second feat despite added complexity.

The 18.6 kWh battery enables up to 42 miles of electric-only driving, chargeable at 7.4 kW via a home wallbox. In hybrid mode, expect 16-17 mpg combined, improving with disciplined electric use. However, full-throttle runs can drop efficiency to under 10 mpg, akin to a high-performance truck. A ‘Boost’ function via paddle shift unleashes maximum ferocity, flashing alerts in the head-up display for track-like surges.

• Combined output: 717 hp and massive torque for instant response.
• EV range: Practical for daily commutes, reducing fuel costs.
• Transmission: 8-speed automatic with launch control for repeatable launches.

Chassis and Handling: Taming the Heavyweight

Weighing around 5,251 pounds—nearly 1,000 pounds more than its predecessor—the M5 defies expectations with composed handling. All-wheel drive with rear bias, an active rear differential, and customizable traction settings allow rear-wheel-drive mode for tire-shredding fun or maximum grip.

The double-wishbone front and five-link rear suspension, paired with adaptive dampers, strike a balance between comfort and sportiness. Comfort mode absorbs bumps luxuriously, while Sport Plus firms up for precise cornering. Steering offers phenomenal directional accuracy but limited feedback, prioritizing stability over raw feel.

Braking shines with standard strong stoppers or optional $8,500 carbon-ceramic units that resist fade during aggressive driving. Wider track (3.0 inches front, 1.9 rear) and exclusive body panels enhance stance and aerodynamics, shod in 285/295 Hankook Ventus tires.

Striking Exterior Design: Aggressive Yet Elegant

The M5’s exterior evolves the 5 Series with M-specific flair. A massive horizontal grille features ‘Iconic Glow’ LEDs for nighttime recognition, flanked by large intakes and a motorsport-inspired apron. Widened fenders house 21-inch M double-spoke wheels, emphasizing the muscular track.

Side profiles reveal bespoke panels without add-on flares, culminating in a subtle rear diffuser and quad exhausts. Aerodynamic tweaks and optional carbon roof minimize weight in the lightest configs. This design signals power discreetly, blending luxury sedan poise with super-sedan menace.

Luxury Interior: Tech Haven for Long Hauls

Inside, the M5 elevates to near-M7 territory. Expansive massaging seats with thick bolsters offer endless adjustments; rear space impresses for adults. A slim dashboard flows into a carbon-fiber curl, with an ‘interaction bar’ of crystalline glass and ambient lighting that shifts red-blue in sport modes.

The flat-bottom steering wheel includes a 12 o’clock marker, and seatbelts flash matching stitching. BMW’s iDrive system integrates adaptive cruise, lane-keeping, and parking aids seamlessly, enhancing daily usability without intrusion. Despite some critiques on material feel, the cabin prioritizes ergonomics and tech.

• Seating: Supportive fronts, spacious rears with luxury features.
• Infotainment: Curved displays, wireless Apple CarPlay/Android Auto.
• Customization: Ambient lighting, optional red seats for flair.

Real-World Performance: Daily Driver or Track Monster?

Owners and testers praise the M5’s versatility. It cruises effortlessly on highways, with hybrid smoothness masking its V8 rumble until provoked. City driving benefits from EV mode and aids, though weight demands respect in tight maneuvers.

On twisty roads, chassis balance shines—nimble at speed, confidence-inspiring brakes, and AWD traction excel in all conditions. Fuel economy rewards plug-in use, but enthusiasts note it’s no lightweight dancer like past models; it’s a precise heavyweight.

Six-month ownership highlights reliability, though interior quality drew mixed views. Efficiency hovers realistically at 16-20 mpg mixed, far better than pure V8 predecessors when charged.

Pricing and Rivals: Value in the Super Sedan Segment

Starting around $120,000, the 2026 M5 undercuts some rivals while offering hybrid tech. Options like carbon brakes and ceramics push toward $150,000+. Competitors include Mercedes-AMG E63 (hybrid incoming), Audi RS7, and Cadillac CT5-V Blackwing.

Pros and Cons at a Glance

• Pros: Explosive acceleration, versatile hybrid system, luxurious ride/comfort, spacious interior, advanced AWD.
• Cons: Hefty weight impacts agility, numb steering feel, complex menus, thirsty under hard use.
