Porsche is understood to be developing two-door coupé and cabrio versions of the Panamera designed to rival the BMW 8 Series and Aston Martin Vantage. 

According to reports, which senior figures at the firm have not denied, Porsche is developing the two variants of its grand tourer for a planned unveiling next year. The cars are designed to offer enhanced practicality and space over the 911 but still be considered as 2+2s rather than outright four-seaters. 

Asked about the possibility of such cars, Porsche design boss Michael Mauer, who designed the original Panamera, said: “As a designer there are no limits to what I can conceive. I believe it is the design department’s role to sketch and consider every model it can for the future so that we are ready should anyone wish to pursue a project. 

“But if you are asking me to confirm if such projects are on the way then you are going to be disappointed. It is not my role to consider such things.” 

Reports in German media suggest plans for the cars are already well advanced and speculate that they will sit on shortened versions of the Panamera’s MSB platform. Were a version of the 2015 Bentley EXP10 Speed 6 concept to be given the go-ahead (unlikely, given recent reports), it is possible that this too could use the platform, bringing a further economy of scale. 

There is also a suggestion the cars will not carry the Panamera name, to fit a sportier, less practical end of the market. But powertrain options are expected to be taken from the Panamera range and include a plug-in hybrid option, given the need to reduce overall fleet emissions and the fact that more than half of European Panamera buyers opt for that set-up at present.
