- A digital artist reimagined the wagon-only 05 GT as a four-door sedan.
- The render revives the spirit of the much-loved Alpina B5 in classic form.
- Bovensiepen’s real 05 GT makes 790 hp from an upgraded M5 hybrid V8.
As much as we love a wagon, the recent reveal of the limited-production Bovensiepen 05 GT built on the M5 Touring left everyone wondering whether the same recipe would work on a sedan. Independent digital artist Theophilus Chin answered the question himself, rendering a spiritual successor to the much-loved Alpina B5 in classic four-door form.
The real Bovensiepen 05 GT comes from the family that founded Alpina, built after the marque became an official sub-brand under the BMW Group. Based on the M5 Touring, its deliberately understated styling is the work of design veteran Frank Stephenson, and it sticks to the wolf-in-sheep’s-clothing formula that defined Alpina for decades.

So Theottle grafted the Bovensiepen’s custom bumpers and side skirts onto the M5 sedan. He carried over the multi-spoke forged alloys too, but swapped the wagon’s silver finish for a deep blue. The darker shade lets the silver bumper-intake accent and the quad tailpipes pop, while paying homage to the Alpina heritage of the tuner.

The Bovensiepen 05 GT is fitted with an upgraded version of the M5’s plug-in hybrid powertrain. The twin-turbo 4.4-liter V8 and the electric motor produce a combined 790 hp (589 kW / 801 PS) and 1,100 Nm (811 lb-ft) of torque. This represents an increase of 72 hp (54 kW) and 100 Nm (74 lb-ft) compared to the M5’s powertrain. The gains come from a reworked ECU, a revised air intake, and a titanium Akrapovic exhaust.

On performance, the wagon promises a 0-100 km/h (0-62 mph) sprint in 3.6 seconds and a top speed of 305 km/h (190 mph). A sedan version would theoretically edge ahead, thanks to the weight savings that come with it.
Will They Make It?
The Bovensiepen 05 GT wagon.
For now, Bovensiepen has no sedan version of the 05 GT on the cards, choosing instead to keep the car faithful to the Touring shape that started the whole project. Anyone holding out for a four-door will have to make do with Theottle’s renderings.
Still, we can always hope for an expanded lineup of BMW-based models in the coming years. Anything new would likely arrive once the Neue Klasse mid-lifecycle updates and next-generation cars have landed, carrying the brand’s fresh design language but stopping short of the hard-edged stance the M division builds its reputation on.
