Developed in-house at Porsche’s R&D centre in Weissach, Germany, the twin-turbo V6 is understood to have a 90deg vee and a capacity of 3.0 litres. It is believed to be a variant of the 3.6-litre V6 that powers entry-level Cayenne and Panamera models.
Peak power and torque are said to be in the region of 370bhp and 400lb ft thanks to twin sequential Borg Warner turbochargers, an air-to-air intercooler system and other internal modifications, including a lower compression ratio than that of the normally aspirated 3.6-litre engine. That’s an increase of about 80bhp and 105lb ft over the non-turbo 3.6.
