The family that turned Alpina into a legend just dropped an 800-hp Gran Turismo
Frank Stephenson penned it, Akrapovič shaped its sound, and Pirelli built bespoke tyres with BOV on the sidewall. Welcome to Fine Driving — at €198,900.
The family that once turned Alpina into a legend sold the brand to BMW and started over — under their own surname. Their first car, the Zagato, was a statement. The second one is the actual product. Meet the Bovensiepen 05 GT. Not just “another tuned BMW,” but a standalone Gran Turismo with an 800-hp plug-in hybrid powertrain, a body shaped by Frank Stephenson, and bespoke Pirelli tyres with BOV stamped into the sidewall.
Technically, the 05 GT is built on the BMW 5 Series platform and uses the M5’s powertrain — but in Buchloe they retuned it properly. A new air intake, a titanium Akrapovič exhaust, revised engine software — system output now stands at 589 kW, or 800 hp, with a crushing 1,100 Nm of torque. Zero to 100 km/h takes less than 3.6 seconds. Top speed is 305 km/h. Kerb weight is 2,555 kg, length over five metres. It’s a PHEV, and on the WLTP cycle it sips 5.3 l/100 km plus 17.0 kWh/100 km, with CO₂ emissions of 124 g/km. The engine was fine-tuned at the Papenburg and Nardò proving grounds — in summer and in winter.
The price bites. The Bovensiepen 05 GT starts at €198,900 in Germany including 19% VAT — roughly €50,000 above a standard BMW M5. That gets you Frank Stephenson’s new bodywork, the titanium Akrapovič exhaust (7.8 kg lighter than the standard stainless setup, with a bass-heavy sound to match) and a leather interior with a Lavalina® steering wheel. Want the full Lavalina cabin? Add another €20,000. Lavalina, by the way, is a barrel-dyed luxury suede sourced exclusively from carefully selected farms in southern Germany, Austria, Switzerland, and northern Italy.
The design was done by Frank Stephenson — the man behind the original BMW X5, the modern MINI Cooper relaunch, the Ferrari F430, and the McLaren P1. The grille is laser-cut stainless steel. At the rear, four oval titanium tailpipes. A wraparound design line runs along the entire lower body, tying bumpers and sills into a single visual whole — and the colour of that line can be matched to the paintwork. The wheels are 21-inch forged units with twenty milled spokes. The Pirellis are bespoke, developed specifically for this car, with BOV marked on the sidewall. The suspension gets modified support bearings, Eibach springs, and a strut tower brace. Every car is hand-built in Buchloe and carries a numbered production plate. “A treat for all the senses,” says Managing Director Andreas Bovensiepen. Hard to argue with that.
First customer deliveries are scheduled for the fourth quarter of 2026.
Earlier it was reported that G-Power pushed the BMW M5 CS to 900 hp and 333 km/h.
