- Authentic X5 designer Frank Stephenson styled the brand new physique equipment.

There’s a frequent false impression that BMW purchased your complete Alpina firm in 2022. In actuality, it solely acquired the model title. The family-run agency in Buchloe was subsequently rebranded as Bovensiepen and continues to help the autos it constructed by the top of 2025. On the similar time, the household behind Alpina’s 60-year legacy has moved forward with growing new vehicles of its personal.
Final yr, Bovensiepen teamed up with famend Italian coachbuilder Zagato to rework the M4 Convertible right into a carbon-fiber-bodied coupe, marking its first undertaking within the post-BMW period.

Do not Name It An Alpina
However this isn’t an Alpina. The Bovensiepen 05 GT goals to be much more of a grand tourer than BMW’s electrified wagon, because of suspension revisions targeted on consolation. From the Eibach springs to the brand new Pirelli tires, it options quite a few adjustments designed to ship a extra relaxed driving expertise, whether or not you are behind the wheel or using as a passenger.
The discreetly revised physique, that includes a stainless-steel grille and cut up rear spoiler, is complemented by new 21-inch cast wheels. Bovensiepen additionally suits an Akrapovič titanium quad-exhaust system that shaves 17.1 kilos (7.8 kilograms) from the usual setup. Admittedly, that is a drop within the bucket when you think about the automobile suggestions the scales at a hefty 5,632 kilos (2,555 kilograms) in European specification.
Leather-based Aplenty
Inside, the cabin feels instantly acquainted, as it’s largely carried over from the usual M5 Touring. Nevertheless, Bovensiepen has wrapped a lot of the inside in leather-based, extending the fabric to the middle console to raise the sense of luxurious. Simply as the outside may be completed in just about any shade possible, consumers have almost countless choices for customizing the leather-based upholstery.
Very similar to Alpina fashions historically obtained powertrain upgrades, Bovensiepen has additionally reworked the M5 Touring’s coronary heart. Along with the aftermarket exhaust system already talked about, the 05 GT options an upgraded air consumption and revised software program, unlocking 790 horsepower and a large 811 pound-feet (1,100 Newton-meters) of torque.
Satirically, the added muscle arrives at a time when BMW has needed to detune the European-spec M5 to adjust to the upcoming Euro 7 emissions normal. Within the EU, the combustion engine loses 41 horsepower, however an upgraded electrical motor totally compensates for the discount. Because of this, whole system output stays unchanged at 717 horsepower. Bovensiepen’s model delivers a further 73 horsepower and 74 pound-feet (100 Newton-meters) of torque in contrast with the donor automobile.
As you would possibly anticipate, the additional energy, upgraded leather-based, and Frank Stephenson-designed physique equipment come at a premium. The Bovensiepen 05 GT begins at €198,900 in Germany, making it €51,700 costlier than a base BMW M5 Touring. Deliveries are scheduled to start within the fourth quarter of this yr.
Motor1’s Take: As a lot as we like how the automobile is much less in your face than the BMW model, we are able to’t assist however wonder if it will have been much more fascinating with out the plug-in hybrid powertrain. An M5 Touring powered solely by a V8, serving as a non secular successor to the outdated B5, may have made the 05 GT the last word massive luxurious wagon.
However, it’s encouraging to see Bovensiepen carrying the Alpina story ahead, even when it now operates beneath the household title. A brand new BMW Alpina-badged 5 Sequence seems unlikely within the close to time period, because the precedence is on bigger, costlier autos. BMW’s first manufacturing ALPINA mannequin since buying the model title might be a facelifted 7 Sequence, due subsequent yr with each V8 and totally electrical powertrains.
