There is a widespread belief that BMW acquired the full Alpina operation in 2022. Actually, the purchase covered only the brand rights. The family business in Buchloe then became Bovensiepen and keeps servicing its cars until the close of 2025. Meanwhile the family that shaped Alpina over six decades has started work on fresh models.

Last year Bovensiepen partnered with Italian coachbuilder Zagato to turn the M4 Convertible into a carbon-fiber coupe, its first venture after the BMW transition. Now Andreas and Florian Bovensiepen, sons of late founder Burkard Bovensiepen, have enlisted Frank Stephenson to soften the look of the M5 Touring.

The mind behind the original X5 and the current Mini shows his skill remains sharp at 66. Stephenson, who also shaped several Ferrari and McLaren supercars, demonstrates his range reaches wagons too. Bovensiepen's new 05 GT carries the refined air once expected from a future Alpina B5 Touring.

Do Not Label It An Alpina

This model is not an Alpina. The Bovensiepen 05 GT targets a stronger grand-touring character than the electrified BMW wagon through suspension changes aimed at comfort. Eibach springs and fresh Pirelli tires join other updates meant to produce a calmer ride for driver and passengers alike.

The subtle body revisions include a stainless-steel grille and a split rear spoiler, paired with new 21-inch forged wheels. Bovensiepen adds an Akrapovic titanium quad-exhaust that trims 17.1 pounds from the original system. That saving is modest given the car weighs 5,632 pounds in European form.

Leather Throughout The Cabin

The interior stays close to the standard M5 Touring yet Bovensiepen covers large areas in leather, including the center console, to heighten the luxury feel. Exterior colors are nearly unlimited and the same freedom applies to leather choices inside.

Following the Alpina tradition of power upgrades, Bovensiepen has reworked the M5 Touring engine. Along with the new exhaust, an improved intake and updated software raise output to 790 horsepower and 811 pound-feet of torque.

The extra strength arrives while BMW detunes the European M5 for Euro 7 rules. In the EU the combustion engine drops 41 horsepower yet the electric motor offsets the loss, keeping total output at 717 horsepower. Bovensiepen adds 73 horsepower and 74 pound-feet over the donor vehicle.

The added power, extra leather, and Stephenson body kit carry a higher price. The Bovensiepen 05 GT opens at 198,900 euros in Germany, 51,700 euros above a standard M5 Touring. First deliveries start in the fourth quarter of this year.

What do you think?

Motor1's Take: While the car looks less aggressive than the BMW original, it might appeal even more without the plug-in hybrid system. A pure V8 M5 Touring, acting as a true successor to the old B5, could have positioned the 05 GT as the finest large luxury wagon.

Still, it is positive to see Bovensiepen extend the Alpina legacy under the family name. A new BMW Alpina-badged 5 Series seems unlikely soon because focus rests on larger and costlier models. BMW's first production ALPINA model after the brand purchase will be a revised 7 Series arriving next year with V8 and fully electric options.
