Undefined: BMW M5 Expert Review, 717Bhp Hybrid Saloon
Discover the seventh-generation BMW M5: a hybrid super-saloon blending blistering speed, advanced tech, and surprising practicality for modern drivers.
The seventh-generation BMW M5 redefines high-performance saloons with its plug-in hybrid powertrain, delivering 717 horsepower from a twin-turbo V8 combined with an electric motor. This G90 model weighs 2,510kg yet accelerates from 0-62mph in 3.5 seconds, offers a 40-mile electric range, and incorporates cutting-edge chassis tech for unparalleled road grip.
Powertrain Innovation and Performance
At the heart of the new M5 lies a sophisticated plug-in hybrid system pairing a 575bhp 4.4-litre twin-turbo V8 with a 194bhp electric motor, yielding a combined 717bhp. Power routes through an eight-speed M Steptronic transmission to all four wheels, with modes including Hybrid, Electric, eControl, Dynamic, and Dynamic Plus unlocking full potential.
In Electric mode, the M5 achieves up to 40 miles of zero-emission driving, ideal for urban commutes and reducing tax burdens with low CO2 emissions. Switching to Dynamic Plus unleashes the full output, propelling the car with explosive acceleration that belies its mass. Real-world testing reveals phenomenal throttle response, where the electric motor’s instant torque bridges any V8 lag, making launches feel sharper than predecessors.
- Key Performance Stats: 0-62mph in 3.5s; top speed over 190mph (limited); 717bhp combined peak power.
- Selectable 2WD mode sends all power to rear wheels for drift-capable fun on 21-inch rears.
- V8 growl enhanced by synthetic sound, though purists may crave more raw volume.
The gearbox shines in smoother settings for everyday use, while brake regeneration feels natural without harshness. This versatility transforms the M5 from efficient cruiser to track weapon at a button press.
Chassis Dynamics and Driving Experience
Despite its 2.5-tonne weight, the M5 handles like a much lighter machine thanks to four-wheel steering, adaptive M suspension, and vast 20/21-inch tyres. On twisty roads, it grips tenaciously, with precise steering and minimal body roll, making it forgiving yet rewarding for spirited drives.
Four-wheel drive provides confidence in wet conditions, while rear-biased torque distribution preserves M-car playfulness. The cabin feels substantial but not overwhelming, with a dashboard lower than rivals like Mercedes, aiding visibility and reducing intimidation for daily duties.
| Driving Mode | Power Output | Drivetrain | Best For |
|---|---|---|---|
| Hybrid | Balanced | 4WD | Efficiency & versatility |
| Electric | 194bhp | 4WD | Zero-emission runs |
| Dynamic Plus | 717bhp | 4WD/2WD opt. | Maximum performance |
Long-distance comfort is exemplary, as proven in endurance tests spanning hundreds of miles, where the adaptive dampers absorb imperfections without compromising agility.
Interior Comfort and Practicality
The G90 M5 expands on the standard 5 Series with greater rear legroom and headroom, accommodating adults comfortably on long trips. Up front, sport seats offer excellent support, wrapped in premium leather with M-specific stitching.
The curved dual-screen infotainment—14.9-inch touchscreen and 12.3-inch driver display—runs iDrive 8.5 with intuitive voice controls and augmented reality navigation. Ambient lighting and carbon-fibre accents elevate the cockpit feel, though the minimalistic design prioritises function over flair.
Boot space suffers from the PHEV battery: 466 litres in the saloon versus 490 in the i5 or 535 in an Audi RS7. Opt for the M5 Touring estate for 500 litres plus a fold-flat floor, enhancing family utility without diluting performance.
Safety Features and Reliability
Safety is robust, inheriting the 5 Series’ five-star Euro NCAP rating from the i5 test in 2023, excelling in vulnerable road user protection (86% score). Standard kit includes adaptive cruise, lane-keeping, and a 360-camera. The chassis, reinforced for high-speed stability, includes multiple airbags and automatic emergency braking.
Reliability data is emerging for this new model, but BMW’s M division history suggests strong build quality. Warranty covers four years/50,000 miles, with hybrid components backed longer.
BMW M5 Touring: Estate Alternative
For those needing more cargo, the M5 Touring mirrors saloon performance with added practicality. Its 500-litre boot expands to over 1,500 litres seats-folded, and the flexible PHEV system delivers similar e-range. Chassis tuning remains superb, balancing load-hauling with dynamism—arguably the most versatile M5 yet.
- Pros: Vast estate space; same hybrid punch; charismatic V8.
- Cons: Higher price; reduced saloon boot.
Ownership Costs and Running Expenses
Starting around £110,000, the M5 undercuts some rivals while offering PHEV tax perks. Fuel economy hits 30+mpg in hybrid mode with charging; electricity costs plummet running expenses. Tyres and brakes demand premium replacements due to performance.
Service intervals are 2 years/15,000 miles, with BMW’s app enabling remote diagnostics. Resale holds firm for M models, bolstered by hybrid appeal.
Rivals Comparison
The M5 dominates saloons like the Mercedes-AMG E63 (now hybrid too) and Audi RS7, outpacing in EV range and handling purity. Porsche Panamera edges in engine drama but lacks electric usability.
| Model | Power (bhp) | 0-62mph (s) | Boot (L) |
|---|---|---|---|
| BMW M5 | 717 | 3.5 | 466 |
| Audi RS7 | 621 | 3.6 | 535 |
| Mercedes E63 | 603 | 3.4 | 540 |
Technology and Driver Aids
Advanced M Driver tools include drift mode, lap timers, and customizable displays. Four-wheel steering shrinks the turning circle, aiding parking this five-metre beast. Wireless Apple CarPlay/Android Auto integrates seamlessly.
