DevelopmentEdit

In May 2016, the first images of the new car were shown in a press release, with the photographs issued only focusing on the front half of the car, igniting speculation that the car would be the first mid-engined 911 race car.[5] Further reports by the German Auto magazine Auto motor und sport appeared to confirm the speculation, after it was revealed that Porsche had received a technical waiver from the FIA to move the engine forwards, and that Porsche had wanted to base its new GTE Class contender on the Porsche 918 Spyder, but it had been found to be too costly.[6] In October 2016, the unmarked car was spotted testing at the Sebring International Raceway, in Florida.[7] Spy photographs of the car showed a massive diffuser, compared to the current car being campaigned, and a series of air extractors located on the "window panel", suggesting it was mid-engined.[8]

The car was then launched at the 2016 LA Auto Show.[9] At the launch of the car, it was revealed that Porsche did not actually seek, and the car never required any waiver, as the car had been fully legal and within the 2017 GTE rules.[10]
