There is a common misconception that BMW bought the entire Alpina company in 2022. In reality, it only acquired the brand name. The family-run firm in Buchloe was subsequently rebranded as Bovensiepen and continues to support the vehicles it built through the end of 2025. At the same time, the family behind Alpina’s 60-year legacy has moved ahead with developing new cars of its own.
Last year, Bovensiepen teamed up with renowned Italian coachbuilder Zagato to transform the M4 Convertible into a carbon-fiber-bodied coupe, marking its first project in the post-BMW era. Now, Andreas and Florian Bovensiepen, sons of the late Alpina founder Burkard Bovensiepen, have joined forces with Frank Stephenson to give the M5 Touring a subtler appearance.
The designer behind the first-generation X5 and the modern Mini proves he still has it at 66. Stephenson, who also penned several Ferrari and McLaren supercars, shows his talent extends to wagons as well. Bovensiepen’s new 05 GT looks every bit as classy as we imagine a next-generation Alpina B5 Touring would have been.

From the Eibach springs to the new Pirelli tires, it features numerous changes designed to deliver a more relaxed driving experience, whether you're behind the wheel or riding as a passenger.
The discreetly revised body, featuring a stainless-steel grille and split rear spoiler, is complemented by new 21-inch forged wheels. Bovensiepen also fits an Akrapovič titanium quad-exhaust system that shaves 17.1 pounds from the standard setup. Admittedly, that's a drop in the bucket when you consider the vehicle tips the scales at a hefty 5,632 pounds in European specification.
Inside, the cabin feels immediately familiar, as it is largely carried over from the standard M5 Touring. However, Bovensiepen has wrapped much of the interior in leather, extending the material to the center console to elevate the sense of luxury. Just as the exterior can be finished in virtually any color imaginable, buyers have nearly endless options for customizing the leather upholstery.
Much like Alpina models traditionally received powertrain upgrades, Bovensiepen has also reworked the M5 Touring’s heart. In addition to the aftermarket exhaust system already mentioned, the 05 GT features an upgraded air intake and revised software, unlocking 790 horsepower and a massive 811 pound-feet of torque.
Ironically, the added muscle arrives at a time when BMW has had to detune the European-spec M5 to comply with the upcoming Euro 7 emissions standard. In the EU, the combustion engine loses 41 horsepower, but an upgraded electric motor fully compensates for the reduction. As a result, total system output remains unchanged at 717 horsepower. Bovensiepen’s version delivers an additional 73 horsepower and 74 pound-feet of torque compared with the donor car.
As you might expect, the extra power, upgraded leather, and Frank Stephenson-designed body kit come at a premium. The Bovensiepen 05 GT starts at $198,900 in Germany, making it $51,700 more expensive than a base BMW M5 Touring. Deliveries are scheduled to begin in the fourth quarter of this year.
