Company sources reportedly claim the convertible version of the Panamera will have just two-doors to try and keep its weight down and to maximise rigidity but it will retain much of its space in the rear.
The roof is likely to be a soft-top seen on Porsche’s other models, rather than a retractable hard top. It will reportedly cost €11,000 (£10,100) more than the saloon.
Porsche has not officially given the green-light for the Panamera convertible, although development chief Wolfgang Duerheimer hinted that more Panamera variants were possible.
“We have a broad range of 14 derivatives of the 911 that are very successful,” he told German media. “So it stands to reason we should diversify the line-up for the Panamera as well.”
