The top-of-the-line Macan will be the first car powered by Porsche’s still-secret new twin-turbocharged V6 petrol engine, details of which are revealed here for the first time.

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.

Panamera 3.6 V6 (Porsche) and Cayenne 3.6 V6 (VW) , don't share the same engine

what's the difference? it's the some output...

The V6 Cayenne sources its engine from Volkswagen, using the company's veteran VR6 engine used in everything from the Golf, Passat and Touareg. It is built from an iron block and has its cylinders arranged in a 10.6 degree angle rather than a V-engine's conventional 60/90 degree bank. In a sense, it's a bit of an inline-six, but the cylinder angle puts it in between that and a V. It's also very tall and narrow, making it too tall to fit into the Panamera's engine bay.

The engine used in the V6 Panamera models is essentially the Porsche V8 engine with two cylinders chopped off. It's a 90 degree bank, aluminum engine sharing over 40 percent of its components with the V8 but has additional parts [such as a balance shaft] to ensure optimum performance for the V6's construction. Where the VW VR6 is tall and narrow, this one is wider and shallower as well as shorter in the front, hence the gap you see in the front of the Panamera's engine bay.
