BMW M5 2025 Review: 717bhp Hybrid Performance Saloon

The seventh-generation BMW M5 redefines high-performance saloons with its plug-in hybrid powertrain, delivering unmatched acceleration, electric versatility, and refined dynamics. Weighing in at over 2,500kg yet sprinting to 62mph in 3.5 seconds, this G90 model fuses a twin-turbo V8 with electric boost for 717bhp total output.

Powertrain Innovation: V8 Meets Electric Might

At the heart of the new M5 lies a sophisticated plug-in hybrid system combining a 4.4-litre twin-turbo V8 engine producing 575bhp with a 194bhp electric motor, yielding a combined 717bhp and 738lb ft of torque. This setup propels the car from 0-62mph in 3.5 seconds, slightly behind its predecessor but feeling explosively quicker in real-world scenarios due to instant electric torque fill.

Drive modes include Hybrid, Electric, eControl, Dynamic, and Dynamic Plus, with power fully unleashed only in the latter two. Select Electric for up to 40 miles of emission-free driving, ideal for urban commutes, or switch to 2WD rear-drive mode for tyre-smoking drifts with all power to the rear wheels. The eight-speed M Steptronic transmission shifts smoothly, especially in milder settings, while brake regeneration feels natural.

• Hybrid Mode: Balances petrol and electric for efficiency.
• Electric Mode: Silent, zero-emission runs up to 140km/h.
• Dynamic Plus: Full 717bhp with track-ready response.

The V8 retains a charismatic growl, enhanced by synthetic sound in Sport modes, though purists may crave more raw volume compared to rivals like the Porsche Panamera.

Chassis Dynamics: Precision Despite the Weight

Despite its 2,510kg kerb weight, the M5 handles like a much lighter machine thanks to advanced tech: all-wheel drive, four-wheel steering, adaptive M suspension, and massive 21-inch tyres. On twisty roads, it grips tenaciously, with razor-sharp steering and minimal body roll, making it feel agile and planted.

Throttle response is phenomenal, aided by the electric motor’s instant torque, ensuring the car lunges forward without hesitation. In Dynamic Plus, it transforms into a rear-drive beast for sideways fun, while everyday modes prioritize comfort with a compliant ride over B-roads.

This table highlights how the new hybrid edges out in usability while matching raw pace.

Design and Aerodynamics: Aggressive Yet Elegant

The G90 M5 boasts a wider stance, flared arches, and a massive kidney grille flanked by slim LED headlights. Its 5-metre length and low roofline create a muscular profile, with quad exhausts and a subtle rear diffuser emphasizing its M credentials. Aerodynamic tweaks, including active flaps, optimize efficiency and downforce.

Available as saloon or Touring estate, the latter offers 500-litre boot space versus the saloon’s 466 litres, compromised by the underfloor battery. The Touring appeals to families needing practicality without sacrificing thrills.

Interior Refinement: Tech-Laden and Spacious

Inside, the M5 feels premium and driver-focused, with a curved dual-screen dashboard (iDrive 8.5 infotainment and digital cluster). Carbon-fibre accents, M Sport seats with massage functions, and Alcantara trim elevate the cabin. Rear space is generous for a performance saloon, surpassing the M3, though the low dashboard aids visibility despite the car’s bulk.

Boot capacity lags rivals like the Audi RS7 (535 litres) due to PHEV hardware, but folding seats expand versatility. Ambient lighting and a panoramic roof enhance the luxurious vibe.

Fuel Efficiency and Running Costs

Official figures claim 30+mpg in hybrid mode, with low CO2 emissions (under 50g/km) minimizing tax. The 40-mile EV range suits short trips, reducing fuel stops on long hauls. Pricing starts around £110,000, competitive against Mercedes-AMG E63 or Porsche Panamera, with Touring variants up to £128,000.

Expect strong residuals and M servicing perks, though tyres and brakes will demand budget due to performance.

Safety and Reliability: Built to Endure

The related BMW i5 earned five Euro NCAP stars in 2023, with 86% for vulnerable road users—the year’s best. The M5 inherits adaptive cruise, lane-keep, and emergency braking, plus chassis reinforcements for high-speed stability. BMW’s reliability remains solid, with hybrid components warrantied robustly.

BMW M5 vs Rivals: How It Stacks Up

The M5 outpaces the Mercedes-AMG E63 S (603bhp) in EV usability and matches the Audi RS7’s practicality. Versus the Porsche Panamera Turbo S, it offers better value but less engine theatre.

• Pros: Explosive hybrid performance, sharp handling, spacious interior, EV range.
• Cons: Heavy weight, reduced boot space, high price.

Ownership Experience: Daily Driver or Track Toy?

Long-distance tests confirm comfort over 700 miles, with supple suspension and quiet cruising. It’s a versatile grand tourer, equally at home shredding tracks or ferrying families.
