The Bovensiepen 05 GT is a low-volume super-wagon and the second model from Bovensiepen Automobile, the Buchloe marque set up by the Bovensiepen brothers after Alpina passed under BMW’s control in early 2026. It follows the brand’s Zagato-bodied coupe and takes the BMW M5 Touring as its starting point.
At its heart is BMW’s S68 plug-in-hybrid system: 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. Where the donor M5 Touring produces a combined 727 hp, Bovensiepen lifts output 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.
The exterior was reworked by Frank Stephenson, with new bumpers, a grille lettered with the Bovensiepen name, forged 21-inch wheels, Pirelli BOV tyres and Eibach springs. 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.
Production is capped at up to 100 cars a year, with deliveries from the fourth quarter of 2026. In Germany the 05 GT starts at EUR 198,900; the donor M5 Touring lists from EUR 147,200.
