BMW M5 UK Road Test: 727bhp Hybrid, 42-Mile EV Range

The BMW M5 stands as a pinnacle of super saloon engineering, merging ferocious power with modern hybrid technology for an unmatched driving experience. This latest iteration delivers over 700 horsepower, electric-only range, and adaptive dynamics that make it a versatile performer on UK roads.

Powertrain Evolution: From V8 to Hybrid Supremacy

At the heart of the new BMW M5 lies a sophisticated plug-in hybrid system, pairing a 4.4-litre twin-turbo V8 with an electric motor to produce a staggering 727bhp and immense torque. This setup propels the car from 0-62mph in just 3.5 seconds, with a top speed exceeding 155mph when equipped with the optional M Driver’s Package.

Unlike its purely combustion-powered predecessors, this M5 introduces up to 42 miles of electric-only driving, ideal for low-speed urban commutes or tax-efficient company car use with a 9% BIK rating. The V8 retains its signature growl, but turbocharging ensures torque arrives early from under 2,500rpm, providing relentless pull without lag.

Drive modes abound: Comfort for serene cruising, Sport for sharper responses, and Track for circuit duty. Customizable M buttons on the steering wheel allow saving preferred setups, enhancing personalization. In EV mode, the M5 glides silently, transforming into a luxury EV until battery depletion triggers seamless hybrid operation.

Chassis Dynamics: Mastering Weight with Precision

Despite a kerbweight approaching 2.5 tonnes, BMW’s engineers have crafted a chassis that defies its mass. All-wheel drive with rear bias, an active rear differential, and selectable 2WD mode enable controlled drifts and explosive launches.

On twisty UK B-roads, the M5 excels with sharp steering and composed body control. Adaptive dampers soften for pothole-ridden surfaces in Comfort mode, yet firm up for spirited driving. The M Dynamic Mode offers traction calibrations from full AWD grip to rear-drive thrills, unlocking playful handling without compromising safety.

Braking is confident with standard M Compound discs, while lightweight options in CS variants further sharpen responses. The result is a car that feels lighter and more agile than its specs suggest, balancing track prowess with grand tourer poise.

Interior Refinement: Luxury Meets Performance

Step inside, and the M5 envelops occupants in premium materials and cutting-edge tech. The BMW Curved Display runs iDrive 8.5, offering intuitive controls via touchscreen and haptic feedback. Merino leather seats with heating, four-zone climate, and ambient lighting create a cockpit worthy of high-end saloons.

• 21/22-inch alloy wheels standard, filling arches aggressively.
• Bowers & Wilkins surround sound for immersive audio.
• Comfort access keyless entry and power tailgate for ease.
• 530-litre boot accommodates luggage despite hybrid battery.

Visibility is good for a performance car, with digital mirrors optional. Rear space suits adults for cross-country trips, though the Touring estate variant adds practicality for families.

Performance on UK Roads: Real-World Thrills

Firing up the M5 reveals its dual personality. In Comfort, it wafts along motorways at 70mph yielding 28mpg averages, sipping fuel efficiently. Push harder on undulating roads, and the hybrid system unleashes seamless acceleration, pinning occupants back with linear surge.

At circuits like Cadwell Park, economy plummets, but lap times impress with launch control and grip. Top speed runs demand the Driver’s Pack for 177mph capability, where stability shines. Wet UK conditions highlight AWD traction, preventing slip-ups during aggressive cornering.

Economy varies: 188mpg official figures reflect hybrid efficiency, but real-world mixed driving nets mid-20s mpg without charging. Regular DC fast-charging supports longer journeys, minimizing range anxiety.

Pricing and Ownership: Premium Costs Analyzed

Starting at £111,440 P11D, the M5 targets affluent buyers. Options like the Driver’s Pack (£2,200) and carbon ceramics escalate totals past £115,000. Running costs include low 9% BIK (£167-£334 monthly at 20/40% tax) and 35g/km CO2, a boon for fleets.

Residuals hold at 36% after three years, softening depreciation. Warranty and BMW service plans mitigate upkeep, though tyres wear quickly under hard use.

Competitors and Verdict: Does It Top the Class?

Rivals like Mercedes-AMG E63 and Audi RS7 offer similar power, but the M5’s hybrid edge and EV range set it apart. It’s heavier yet more controllable, prioritizing versatility over raw lightness.

Critics note the weight as a potential flaw, but advanced chassis tuning masks it effectively. For enthusiasts, it’s a technological marvel; for daily drivers, a refined cruiser.
