To our shock, the Speedtop isn’t the one coachbuilt BMW debuting this weekend on the Concorso d’Eleganza Villa d’Este. It won’t 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 based mostly in Buchloe, the place the most recent member of the BMW Group calls dwelling.
Primarily based on the M4 facelift launched final yr, the Bovensiepen Zagato contains a bespoke physique with the Italian design home’s signature double-bubble roof. Gone are BMW’s hanging kidneys, changed by a extra delicate 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 constructed from carbon fiber.
Even the trunk lid has been reshaped to accommodate a delicate ducktail spoiler, far much less hanging than the one on the M2 CS, additionally unveiled on the shores of Lake Como. The general styling leans towards an aesthetic grand tourer slightly than an aggressive coupe. The flexibility to roll down the rear-side home windows and the absence of B-pillars recommend the Bovensiepen Zagato is predicated on the M4 Convertible (G83), however with a set roof as a substitute.
Whereas the outside distances itself from its BMW roots, the cabin nonetheless screams M4. However although the inside is essentially carried over, Bovensiepen spends over 130 hours on every automobile to put in full Lavalina leather-based. Prospects can select from dozens of leather-based colours and pair them with Alcantara. In whole, the automobile requires 250 hours to finish and contains greater than 400 bespoke components. The rear bench reinforces our opinion that the automobile is predicated on the G83.
At this level, you’re most likely 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 provide 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 automobile is probably going the G83, the brand new coupe comes solely with all-wheel drive. By extension, it’s obtainable solely with an automated 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 cast wheels, Bilstein dampers, and an Akrapovic titanium exhaust system.
Bovensiepen will announce pricing particulars and manufacturing numbers within the fourth quarter of the yr. We think about will probably be considerably dearer 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 offered solely as Gran Coupes. The newcomer gained’t compete straight with these fashions, particularly given its possible increased value level.
