Bovensiepen 05 GT: The 790bhp Luxury Estate That Carries On Where Alpina Left Off
Sometimes the most exciting automotive reveals happen without any fanfare at all. When journalists gathered in Austria to sample the new Bovensiepen Zagato, few could have predicted that a second, entirely separate Bovensiepen model would suddenly appear on the scene — one packing a jaw-dropping 790bhp and available to drive on the same day. That car is the Bovensiepen 05 GT, and it may well be one of the most compelling performance estates money can buy right now.
A Name You Might Not Know — But a Legacy You Definitely Do
If the Bovensiepen name doesn't immediately ring a bell, the family history almost certainly will. The Bovensiepens were the custodians of the legendary Alpina brand for decades, producing some of the finest BMW-based performance and luxury machines ever to turn a wheel. That all changed when BMW acquired the Alpina naming rights, repositioning the badge as a trim level for lavish versions of the 7 Series rather than a stand-alone engineering exercise built on a wide range of models.
Rather than fading quietly into retirement, however, the Bovensiepen family chose to carry on doing what they have always done best. The result is a new, independent marque bearing their own surname — and the 05 GT is among the first fruits of that reborn ambition. Anyone who spent time admiring the old Alpina B5 will find the conceptual DNA of the 05 GT immediately familiar, and that is very much the point.
What Is the Bovensiepen 05 GT?
At its core, the Bovensiepen 05 GT follows the same philosophy that made the Alpina B5 so beloved among enthusiasts and grand touring devotees alike. Start with a mainstream BMW platform — in this case the current BMW 5 Series — refine the aesthetics with a touch of sporting elegance, rework the suspension geometry with long-distance comfort firmly in mind, significantly increase power output, and then lavish the interior with the finest leathers and handcrafted details available. It is a formula that served Alpina extraordinarily well across multiple generations, and there is absolutely nothing wrong with sticking to a winning formula.
The 05 GT designation itself carries clear echoes of the old B5, with the "05" nodding to the 5 Series underpinnings. The "GT" suffix signals grand touring intent — this is emphatically not a track day weapon, but rather a continent-crushing express capable of moving four or five people and their luggage at extraordinary speed while keeping everyone on board supremely comfortable.
790bhp: Faster Than an M5 Touring
Let's address the headline figure head-on. The Bovensiepen 05 GT produces 790bhp, which places it comfortably ahead of the already formidable BMW M5 Touring in outright power terms. That is a remarkable achievement for what is, on the surface, a relatively restrained-looking estate car. The Bovensiepens have never been interested in building something that screams for attention at every traffic light; they have always preferred to let the engineering do the talking, and the 05 GT continues that tradition without compromise.
What makes that power figure even more impressive is just how discreet the 05 GT appears from the outside. Where rivals might festoon a high-performance estate with aggressive body kits, oversized wings, and shouty exhaust exits, the 05 GT carries itself with the kind of quiet confidence you might expect from a well-dressed professional rather than a weekend racer. In profile, it could almost pass for a well-specified standard 5 Series — perhaps a 530e M Sport — which is precisely the sort of understatement that Alpina customers always adored.
Suspension, Comfort, and the Art of the Grand Tourer
Power alone does not define a great grand tourer. The Bovensiepen 05 GT has been developed with a carefully revised suspension setup that prioritises ride quality and long-distance composure without sacrificing the dynamic polish needed to justify those performance credentials. The Bovensiepen family has always understood that the truly great performance car is one that can cover 600 miles in a single day without leaving its occupants exhausted, and that philosophy is woven into every aspect of the 05 GT's engineering brief.
- Revised suspension tuning focused on ride comfort and high-speed stability
- 790bhp power output exceeding the BMW M5 Touring
- BMW 5 Series platform providing a proven, refined foundation
- Handcrafted leather interior appointments in the Alpina tradition
- Subtle exterior styling that avoids ostentation while hinting at the performance within
Interior: Where Craftsmanship Meets Performance
Step inside the 05 GT and the Bovensiepen philosophy becomes immediately tangible. The cabin is trimmed with high-quality leather throughout, with attention to detail that reflects the family's long tradition of bespoke finishing. Customers can expect a level of personalisation more akin to a coachbuilder than a mainstream manufacturer, choosing from a range of hide colours, stitching patterns, and material combinations to create something genuinely unique. It is the kind of craftsmanship that justified Alpina's premium pricing for decades, and it translates seamlessly to the Bovensiepen brand.
The Alpina B5 Is Dead — Long Live the Bovensiepen 05 GT
With BMW having absorbed the Alpina name for its own flagship luxury saloon programme, many enthusiasts mourned the apparent end of the Bovensiepen formula. The arrival of the 05 GT makes it abundantly clear that those concerns were premature. The spirit, the engineering philosophy, and the extraordinary attention to detail that defined the Alpina B5 for a generation are alive and well — they simply carry a different badge now.
For anyone who has ever wanted a car that can embarrass almost anything on a motorway while attracting less attention than a standard company car, the Bovensiepen 05 GT deserves very serious consideration. It is fast, refined, beautifully built, and rooted in one of the most respected traditions in automotive performance tuning. The Bovensiepen legacy continues, and on this evidence, it continues in very fine style indeed.
