To our shock, the Speedtop isn’t the one coachbuilt BMW debuting this weekend on the Concorso d’Eleganza Villa d’Este. It may not carry the roundel, however this new efficiency coupe is clearly an M4 with a beautiful physique penned by Zagato. Andreas and Florian Bovensiepen, sons of the late ALPINA founder Burkard Bovensiepen, have created a brand new firm bearing the household title. Unsurprisingly, it’s additionally primarily based in Buchloe, the place the latest member of the BMW Group calls house.
Based mostly on the M4 facelift launched final 12 months, the Bovensiepen Zagato contains a bespoke physique with the Italian design home’s signature double-bubble roof. Gone are BMW’s placing kidneys, changed by a extra refined chrome steel grille. Its black honeycomb sample is repeated on the massive air intakes. Whereas the M4 silhouette is immediately acquainted, the physique panels are all new, and most are made out of carbon fiber.
Even the trunk lid has been reshaped to accommodate a refined ducktail spoiler, far much less placing than the one on the M2 CS, additionally unveiled on the shores of Lake Como. The general styling leans towards a cultured grand tourer relatively than an aggressive coupe. The flexibility to roll down the rear-side home windows and the absence of B-pillars recommend the Bovensiepen Zagato relies on the M4 Convertible (G83), however with a set roof as an alternative.
Whereas the outside distances itself from its BMW roots, the cabin nonetheless screams M4. However despite the fact that the inside is essentially carried over, Bovensiepen spends over 130 hours on every automotive to put in full Lavalina leather-based. Prospects can select from dozens of leather-based colours and pair them with Alcantara. In complete, the automobile requires 250 hours to finish and contains greater than 400 bespoke elements. The rear bench reinforces our opinion that the automotive relies on the G83.
At this level, you’re in all probability questioning what powers it. The Bovensiepen Zagato makes use of a 3.0-liter inline-six engine, presumably the twin-turbo S58 from the M4. Nevertheless, it’s been tuned right here to supply 602 hp. That’s a rise of 79 hp over the M4 Convertible. Torque climbs by 50 Nm (37 lb-ft) to 700 Nm (516 lb-ft) in comparison with the usual mannequin. For the reason that donor automotive is probably going the G83, the brand new coupe comes solely with all-wheel drive. By extension, it’s out there solely with an computerized transmission.
For efficiency, it sprints from 0 to 62 mph (100 km/h) in simply 3.3 seconds, four-tenths faster than the G83. It tops out at over 186 mph (300 km/h) and weighs 1,875 kilograms (4,134 kilos), much like the droptop M4. Along with its new physique and upgraded engine, the Bovensiepen Zagato options bespoke 20-inch solid wheels, Bilstein dampers, and an Akrapovic titanium exhaust system.
Bovensiepen will announce pricing particulars and manufacturing numbers within the fourth quarter of the 12 months. We think about will probably be considerably costlier than an M4 Convertible, which begins at €112,700 in Germany. Deliveries are set to start within the second quarter of 2026. Whereas ALPINA provides the B4 GT and D4 S, each are bought solely as Gran Coupes. The newcomer gained’t compete instantly with these fashions, particularly given its probably increased value level.
