Bovensiepen Automobile, the Buchloe firm set up by the Bovensiepen brothers after Alpina passed under BMW’s control in early 2026, has revealed its second model. The 05 GT follows the Zagato coupe and turns the BMW M5 Touring into a low-volume super-wagon.
Design
The exterior was reworked by Frank Stephenson, whose past credits include the first-generation BMW X5, the Ferrari F430 and the McLaren P1. The 05 GT gets new bumpers, a grille lettered with the Bovensiepen name, forged 21-inch wheels, Pirelli BOV tyres and Eibach springs.
Powertrain
The car is a plug-in hybrid built on BMW’s S68: a 4.4-litre twin-turbo V8 making 544 hp, paired with a 197 hp electric motor inside an eight-speed automatic and a 22.1 kWh battery good for 67 km of electric range on the WLTP cycle. In the donor M5 Touring the system produces a combined 727 hp. Bovensiepen lifts that to 800 hp and 1100 Nm through revisions to the V8 and an Akrapovic exhaust.
The result is 0-100 km/h in 3.6 seconds and a 305 km/h top speed.
Inside
The cabin is trimmed in Lavalina leather with a free choice of colour and stitching, a hood over the instrument binnacle, aluminium shift paddles and a numbered plaque.
Price and production
In Germany the 05 GT starts at €198,900 (about $214,800); the donor M5 Touring lists from €147,200. Deliveries begin in the fourth quarter of 2026, with output capped at up to 100 cars a year.
