Porsche is adding fuel to the persisting rumors that it’s working on a modern-day 928 GT coupe after our spies caught a test mule based on a shortened version of the next Panamera saloon in Europe.

A similar prototype wearing UK plates registered under Bentley’s name had been spotted in the past in Britain, indicating that it could be a mule for the next Continental GT, which will share its underpinnings with the Panamera II, but this one comes with Porsche registered plates.

The tester is riding on a shorter wheelbase version of Porsche’s new Modular Standard Platform (MSB) fitted under the chopped body of the G2-codenamed 2017 Panamera that will be revealed later this year, while a closer examination of the wheel arches shows that it might be running on wider tracks as well. It also has a wider rear wing at the back that doesn’t match the stock opening.

Should this be a case of Porsche developing a spiritual successor to the iconic 928 Coupe that remained in production for nearly two decades until 1995, the design of the car will probably incorporate styling cues from both the new Panamera and the 911 featuring a more geometric styling than the original. Such a car would compete with Mercedes-Benz’ S-Class Coupe, Bentley’s Continental GT and if another rumor concerning BMW comes into fruition, the 8-Series too.

Naturally, engine and transmission options would be shared with the higher end versions of the 2017 Panamera including its new twin-turbo 4.0-liter V8s in both rear- and all-wheel drive layouts.
