The dream specification for a 2026 BMW M5 Sedan opts for Carbon Black Metallic, a shade that appears inky at dusk yet reveals subtle navy flecks under strong light. Factory wide-body arches, deep front intakes and a supercar-style rear diffuser remain free of additional carbon embellishments, maintaining a purposeful but understated stance. Jet-black 20/21-inch dual-spoke alloys tuck neatly beneath the extended wings, complemented by matching brake callipers that whisper, rather than shout, about the saloon’s intent.

Inside, Dark Violet and Black Merino leather pairs with polished Dark Oak veneer, achieving a balanced mix of sportiness and sophistication. Only two features enhance the base specification: the Driving Assistance Professional suite for semi-autonomous motorway work and M Drive Professional, which unlocks Dynamic and Dynamic + hybrid modes. Weight-adding frills such as a glowing grille, ceramic brakes or extra carbon trim are left on the shelf, preserving the car’s sleeper character and avoiding unnecessary complexity.

Power comes from BMW’s S68 4.4-litre twin-turbo V8 allied to an electric motor integrated within the eight-speed transmission. The petrol unit contributes 577 horsepower, while the motor adds 194, producing a combined 717 horsepower and 738 lb-ft of torque. Launch control sends the saloon to 60 mph in 3.4 seconds, yet the plug-in system also permits up to 40 miles of silent running and an electric top speed of 87 mph—ideal for early-morning departures or zero-emission urban trips.
This dual personality allows the latest M5 to devour challenging B-roads with rear-biased poise, cruise serenely when the drivetrain slips into electric mode, and carry four adults plus luggage in genuine comfort. Its most direct rival, the Porsche Panamera Turbo E-Hybrid, offers similar pace and plug-in versatility but at a higher outlay, underscoring the BMW’s compelling blend of performance, efficiency and everyday practicality.
