The founders of BMW's tuning house Alpina, in collaboration with Italian design house Zagato, revealed a bespoke BMW M4-based grand tourer called Bovensiepen Zagato at Villa d'Este Concorso d'Eleganza on Lake Como.
The Bovensiepen Zagato delivers 443kW of power and 700Nm of torque from its turbocharged 3.0-litre inline six-cylinder engine, surpassing the power outputs of the standard M4 models.
The coachbuilt M4 boasts 0-100km/h acceleration in 3.3 seconds, a top speed of over 300km/h, and features a lightweight titanium exhaust system, bespoke Bilstein dampers, and three driving modes for varying dynamics.
The Zagato-designed body features unique body panels, 'double bubble' roof and rear window, stainless steel grille, carbon-fiber elements, and various branding details. Limited production is set to start after initial deliveries at the end of the second quarter of 2026.
