QP5 GTS Specs are 444 hp from a 4.7 litre ferrari v8 found also in the Granturismo S, sport, mc stradale. Fantastic exhaust note but I think the Granturismo version was always a much nicer body paired with the same engine. (gts version 2009-2013)
QP6 GTS Specs are 530hp and 710 nm torque from a the engine which is a 3.8-litre 90° twin-turbocharged V8 from Ferrari F154 family also found in the Ferrari 488. The QP6 GTS has a weight of 1900kg, this is 100kg lighter than the QP5 GTS. 193 mph top speed. Sound is really nice as well for a biturbo. Another plus is this the engine can easily be ecu tuned stage 1 to 600 plus hp and 820nm plus torque.
Insignificant Parts like the window switches and sat Nav are from fiat/chrysler parts bin in the QP6 GTS 2014-present . However the QP5 GTS 2009-2013 sat nav and sticky switches were terrible and low quality, these bin parts are a huge improvement.
These "How It's Made" videos are sometimes a little frustrating because of little niggling inaccuracies brought about by guys with journalism degrees trying to present a technical subject. But nit picking aside, it is an interesting video.
I see that the newer cars don't use a cam cover gasket. Wonder if it works better or worse than the gaskets on the 4.2/4.7L V8.
