High-performance estate shares its powertrain with the BMW M5 Touring. Bovensiepen was founded by the family behind the Alpina brand. Updated bumpers, new wheels, and cabin tweaks set it apart visually. A year after Bovensiepen burst onto the world stage with its M4-based Zagato coupe, the company has its second car ready. The 05 GT starts life as a BMW 5-Series Touring, goes through a head-to-toe reengineering, and ends up with a power figure fit for a limited run M5. If you’re wondering why the 05 GT looks so much like an Alpina product, there’s a very good reason. Bovensiepen was created by the same family that founded Alpina, the tuning house BMW fully acquired in 2022, and is now releasing products of its own. For the 05 GT, the company recruited the expertise of famed car designer Frank Stephenson, giving it an understated look while still ensuring it stands out from a regular 5-Series. In essence, this is a successor to the old Alpina B5.

A set of 21-inch, 20-spoke forged wheels has also been installed and is wrapped in Pirelli tires created specifically for this car. The alterations continue along the sides with new skirts, while the rear gets a custom spoiler stretching down from the roof, a refined bumper, and quad tailpipes. For the most part it looks like a more restrained Alpina product, badging aside. Alpina may have mixed feelings about that, but a little extra competition in the tuned BMW space can only be a good thing Plug-In Power To Stun No doubt the most impressive thing about the 05 GT is the powertrain. While it looks understated and very similar to a basic 5-Series Touring, it actually uses the same plug-in hybrid, 4.4-liter twin-turbocharged V8 as the M5. Ordinarily, this setup packs 718 hp and 738 lb-ft (1,000 Nm) of torque, but thanks to a new air intake, a titanium Akrapovic exhaust, and some software tweaks, Bovensiepen has extracted 790 hp and 811 lb-ft (1,100 Nm). The luxurious estate can accelerate to 62 mph (100 km/h) in less than 3.6 seconds and reach a top speed of 190 mph (305 km/h). It tips the scales at 5,632 lbs (2,555 kg), making it 11 lbs (5 kg) heavier than an M5 Touring. Other performance-focused changes include tweaked suspension with new Eibach springs, modified support bearings, and a strut tower brace. There’s plenty to like about the car’s cabin, too. The German firm has re-trimmed the seats in new Lavalina leather, sourced from selected farms in Germany, Austria, Switzerland, and Italy. The steering wheel is also newly appointed in plush new leather, and, as you’d expect from a vehicle like this, buyers can choose from a slew of different leather colors to create their dream ride. Bovensiepen plans to start deliveries of the 05 GT in the fourth quarter of the year, with prices starting from €198,900 ($230,700).
