The naturally aspirated direct-injection V8 has just been given a mild upgrade with camshaft revisions, in order to produce 309kW and 515Nm for the Cayenne GTS.
Even though it is not the most powerful Cayenne - that honour goes to the Cayenne Turbo - Porsche describes the GTS as the most "emotional", emphasising the excitement generated by a non-turbo V8 engine.
"The naturally aspirated engine has the fast response; this is only (achieved) with naturally aspirated (engines)," says Bogl to questions about the pros and cons of the "atmo" V8.
"The disadvantage is the consumption."
Bogl says heading down the popular path of turbocharging had its benefits, including reduced weight.
"You can also make the down-size, smaller engines with the same output. The centre of gravity is lower, the consumption is lower."
There is a possibility the V8 engine could live on alongside a smaller turbocharged engine, such as the 3.0-litre twin-turbo, playing on the emotion Porsche emphasised when presenting the Cayenne GTS.
"Maybe we have both, it could depend on the model," says Bogl.
There is potential for the naturally aspirated V8 engine to be deployed in select markets.
"Maybe there are some markets that are not taking so much care about fuel consumption," says Porsche SUV chassis manager Markus Schieritz.
While it may be less efficient as a smaller boosted engine, Porsche points out that this generation Cayenne GTS uses 23 per cent less fuel than the previous-generation version, although much of the gain came from a lighter body.
The new Cayenne GTS weighs 2085kg and records an official fuel consumption rate of 10.7 litres per 100km with the help of idle-stop technology.
