Based on the BMW M5 Touring, the limited-production vehicle offers a significant power increase, bespoke styling by a renowned designer, and extensive customization, positioning itself as a more refined and exclusive grand tourer.

The car is the second model from Bovensiepen, a company formed by the Bovensiepen family after BMW acquired the Alpina brand name in 2022. It follows the M4-based Zagato coupe introduced last year. The 05 GT retains the BMW M5 Touring's plug-in hybrid powertrain, featuring a 4.4-liter twin-turbocharged V8, but engineers have revised the software, intake system, and fitted a titanium Akrapovič exhaust to boost output.
