Markus Sitzler, the Team Lead Vehicle Periphery SUV-Engines, describes the sound as “the sonorousness you would expect from a V8, flavored with a dash of GT racing.” In other words, he says, “the Cayenne GTS Coupe doesn’t sound like a muscle man, it sounds more like a fit athlete.”
The sound is issued from an optional twin-branch sports exhaust system that features centrally located tailpipes. When compared to the previous sports exhaust system with the tailpipes located at the outer edges, the new Porsche Cayenne GTS Coupe releases a throatier sound. This is due to the special internal structure of the silencer, ultimately allowing for a clear acoustic underpinning to the 4.0-liter eight-cylinder engine’s sporty appearance.
So as to avoid unwanted damping, Porsche engineers separated the exhaust tracts from the “two cylinder banks, over the center silencer through to the rear silencer and the outlets to the open air,” explains Sitzler. The final result is a GTS sound that is quieter than under full load while also presenting rich bass tones. Depending on the percentage of the exhaust gas flow passes through the bypass, main tract, and silencer, the new sports exhaust system’s sound varies.
The new Cayenne GTS models now boast 620 Nm of torque, a 20 Nm increase from the predecessors. Within the 4.0-liter V8 Biturbo engine, the exhaust gas turbochargers are carefully arranged to save space within the cylinder V, allowing them to be installed lower in the vehicle. With the Sport Chrono package now fitted as standard to the GTS Coupe, the new Cayenne effortlessly sprints from 0-100 km/h in just 4.5 seconds. This is .6 seconds faster than its predecessor, an impressive cut.
The center sports exhaust system will eventually be available on the Cayenne Turbo Coupe and the Cayenne Turbo S E-Hybrid Coupe.
