Motor1’s latest video review of the 2025 BMW M5 G90 begins by addressing the elephant in the room—its 2,445 kg kerb mass—yet almost immediately shows that the figures fail to tell the full story. Wearing a plug-in-hybrid powertrain that marries a 4.4-litre twin-turbo V8 with a 194 hp electric motor inside the eight-speed automatic gearbox, the super-saloon unleashes a combined 717 hp and 1,000 Nm to all four wheels, burying scepticism beneath a torrent of torque. A floor-mounted 18.6 kWh battery affords roughly 40 km of silent running before the petrol unit joins in, the handover managed with imperceptible finesse according to on-board footage.
Chassis engineers offset the hybrid hardware’s extra 400 kg by widening the track and fitting Integral Active Steering, letting the rear wheels pivot subtly for tighter urban manoeuvres and greater high-speed stability. Adaptive M Suspension samples road data a thousand times per second to keep the body level, while a carbon-intensive structure drops mass where it matters most and lowers the centre of gravity for sharper turn-in. Optional carbon-ceramic discs add yet more stamina, and the brake pedal retains a progressive feel despite the heavy regenerative recuperation that feeds energy back into the pack.
Out on a ribbon of mountain tarmac, the camera captures a saloon that carves through bends with poise, the steering offering genuine feedback rather than artificial heft and the hybrid punch catapulting the car from rest to 100 km/h in an independently timed 3.5 seconds. Select Electric mode and the M5 glides through dawn traffic almost silently, preserving charge for later heroics thanks to an e-Control setting that ring-fences battery energy on demand. Within the cabin, a sweeping dual-screen display, sculpted M seats, and configurable drive-mode paddles deliver a cockpit that feels simultaneously luxurious and purpose-built, reinforcing the car’s split personality as subdued commuter and back-road missile.
BMW executives now admit they misread public reaction by revealing weight figures before anyone turned a wheel; the video proves why those early judgments were premature. By converting mass into grip, balance and zero-emission range, the M5 G90 demonstrates that clever engineering can turn a potential drawback into an outright advantage. After watching the footage, it becomes clear: this is a heavyweight that punches far above its class, redefining what an M-badged four-door can be in the hybrid age.
