The BMW 8-Series Coupe has been joined on the assembly line at the Dingolfing factory in Germany, by its topless sibling, the new 8-Series Convertible.

The brand’s flagship open-top model is being built alongside the 5-Series and 7-Series at the site in Lower Bavaria, which received an investment of less than €100 million (~$114 million) to prepare for the new model family.

With rivals such as the Mercedes-Benz S-Class Cabriolet in its sight, the BMW 8-Series Convertible benefits from a multi-layered soft-top. It opens and closes at the push of a button in 15 seconds, comes in black as standard or Anthracite Silver as an option, and is said to minimize the weight of the car, while providing “superb acoustic insulation” from the outside world.
